Apparatus for transferring electric power from a mobile unit placed in various orientation on a stationary unit

[0001] This application is a Continuation-in-Part of U.S. patent application Ser. No. 12/343,464 filed on Dec. 23, 2008.

[0002] This application claims priority benefits from U.S. patent application Ser. No. 12/343,464 filed on Dec. 23, 2008, which claims priority benefits from U.S. Provisional Patent Application No. 61/019,301, filed on Jan. 7, 2008, herein incorporated by reference in its entirety.

[0003] The present invention relates to an apparatus for transferring electrical power from a source plane to a receiving device placed in various orientations on this plane.

[0004] Many of today's electronic devices are portable and some of them are even equipped with rechargeable batteries.

[0005] If a battery less electronic device is used, it must be connected to a power supply, i.e. 110V/220V AC power outlet.

[0006] When an electronic device equipped with rechargeable batteries is being used, the operating time of the device is limited to the available charge provided by at least one rechargeable battery. After the depletion of the batteries, the device must be connected to a power supply, i.e. 110V/220V AC power outlet in order to continue to operate and to recharge the batteries in the device.

[0007] There are a number of problems associated with conventional means of powering or charging these devices:

[0008] The devices have to be plugged into mains 110V/220V AC power outlet and hence if several are used together, they take up space in plug strips and create a messy and confusing tangle of wires.

[0009] The locations of the power outlets are fixed and the number of outlets is usually limited.

[0010] U.S. Pat. No. 3,521,216, (1970), which is incorporated by reference for all purposes as if fully set forth herein, taught the use of plug and socket assembly incorporating magnetic means for attracting and holding a plug in a socket.

[0011] There is thus a widely recognized need for, and it would be highly advantageous to have a power outlet plug and socket that do not require any alignment at all.

[0012] The prior art does not teach or suggest such a tool.

[0013] An apparatus for transferring electrical power from a source plane, to one receiving device or to a plurality of receiving devices placed in various orientations on this source plane according to the present invention can overcome the described limitations.

[0014] The apparatus includes a planar stationary unit set and at least one mobile unit set.

[0015] According to one embodiment the planar stationary unit set includes conductive plates embedded in the form of a grid in a non-conductive matrix.

[0016] An example for the matrix material could be plastic but the matrix could be made of any material that is non-conductive.

[0017] An example for the conductive plates embedded in the matrix material could be copper, but the conductive plates embedded in the matrix could be made of any material that is conductive.

[0018] Each of the plates is connected to a power grid through a switch that is normally open. i.e., there is no voltage on the plates.

[0019] Half of the plates are connected to the phase port of the electrical power grid and the other half are connected to the zero port of the electrical power grid.

[0020] The port names used hereinafter are symbolic only and are not intended to limit the application of this invention to a specific type of electrical current. The present invention may also be used with a positive port and a negative port as used in direct current (DC) power supplies.

[0021] In the case of a two dimensional stationary unit set, the plates are arranged in grid formation so that the four nearest neighboring plates of each plate are connected to the opposite port as the port that the plate itself is connected to.

[0022] All the switches of the phase port are connected to a signal-receiving device and they can be turned on if in their proximity there is a device that transmits a specific signal to the receiving device.

[0023] This transmitting device can transmit the signal (or code) through any form of transmission such as magnetic transmission, electromagnetic transmission, electrostatic transmission (capacitance), radio frequency (RF) transmission etc.

[0024] All of the switches of the zero port are connected to a signal-receiving device and they can be turned on if in their proximity there is a device that transmits a specific signal (or code) to the receiving device.

[0025] This transmitting device can transmit the signal (or code) through any form of transmission such as magnetic transmission, electromagnetic transmission, electrostatic transmission (capacitance), radio frequency (RF) transmission etc.

[0026] The phase port switch cannot be turned on by the same transmission that turns on the zero port switches and the zero port switches cannot be turned on by the same transmission that turns on the phase port switches.

[0027] According to the above embodiment, a mobile unit set that is comprised of two large conductive plates is embedded in a planar and non-conductive frame.

[0028] The plates in the mobile unit set are significantly bigger than the distances between the plates in the planar stationary unit set so that if placed on the planar stationary unit set, each of the two plates in the mobile unit set covers several plates embedded in the planar stationary unit set.

[0029] The distance between the plates in the mobile unit set is greater than the largest dimension of the plates in the planar stationary unit set so that no plate in the planar stationary unit set can be in contact with both plates in the mobile unit set.

[0030] The width of the non-conductive frame surrounding the conductive plates is grater than the largest dimension of the plates in the planar stationary unit set so that no plate in the planar stationary unit set can touch a plane and extend beyond the frame at the same time. This is required for safety reasons: it is not permissible that a live plate would be exposed; hence, the mobile unit set must cover it.

[0031] Behind each plate in the mobile unit set there is a transmitting device as mentioned before.

[0032] Each transmitting device in the mobile unit set is transmitting a different signal (or code).

[0033] One transmitting device is transmitting the signal (or code) that causes the phase port switches to turn on.

[0034] The opposite transmitting device is transmitting the signal (or code) that causes the zero port switches to turn on.

[0035] The plate that has the transmitting device that is transmitting the signal (or code) that causes the phase port switches to turn on is called the “phase plate”.

[0036] The plate that has the transmitting device that is transmitting the signal (or code) that causes the zero port switches to turn on is called the “zero plate”.

[0037] Following is a summary of the stages of the method according to the present invention:

[0038] When the mobile unit set is placed on the planar stationary unit, both its zero plate and the phase plate are in contact with plates that are connected to the phase port and with plates that are connected to the zero port in the stationary unit.

[0039] Of the plates that are in contact with the phase plate, only the switches that are connected to the phase port are switched on and thus an electrical connection is established between the phase plate and the phase port through the live plates.

[0040] Of the plates that are in contact with the zero plate, only the switches that are connected to the zero port are switched on and thus an electrical connection is established between the zero plate and the zero port through the live plates.

[0041] When any other device or being touches the planar stationary unit, and is in contact with the plates, it is not in electrical contact with the phase port or the zero port because the switches between the plates and the phase and zero ports are not on, thus, the exposed plates in the stationary unit are not “live” and are safe to touch.

[0209] Referring now to the drawings, FIG. 2a is a side view schematic illustration of an exemplary, illustrative embodiment of a magnetic switch phase assembly 40, according to the present invention.

[0210] FIG. 2b is a partial cut-away side view schematic illustration of an exemplary, illustrative embodiment of a magnetic switch phase assembly 40, according to the present invention.

[0211] The figure depicts the elements comprising the magnetic switch phase assembly 40, and the way they are arranged with regards to each other, while omitting the magnetic switch phase assembly voltage element spring 40g, (not shown in the present illustration), and the magnetic switch phase wire 40j, (not shown in the present illustration).

[0212] The magnetic switch phase assembly 40 has a magnetic switch phase assembly housing 40h, which is electrically non-conductive, a magnetic switch phase assembly contact element 40a, designed to conduct electricity when in contact with a mobile unit phase assembly 20, (not shown in the present illustration), and is located at one outer edge of the magnetic switch phase assembly 40, a magnetic switch phase assembly shaft 40c, which is electrically non-conductive, is located in the middle of the magnetic switch phase assembly housing 40h, on which other elements may travel over, such as a magnetic switch phase assembly voltage element 40b, receiving an electrical voltage by means of a magnetic switch phase wire 40j, (not shown in the present illustration), and a magnetic switch phase assembly magnet 40e, attached to a magnetic switch phase assembly magnet spring 40f. The magnetic switch phase assembly 40 is sealed at the opposite end of the magnetic switch phase assembly contact element 40a by a magnetic switch phase assembly housing end disk 40i.

[0213] FIG. 2c is a partial cut-away side view schematic illustration of an exemplary, illustrative embodiment of a magnetic switch phase assembly 40, according to the present invention.

[0214] This figure depicts the magnetic switch phase wire 40j. In normal operation the magnetic switch phase assembly voltage element spring 40g ensures that there is a first gap 40z between the magnetic switch phase assembly contact element 40a, and the magnetic switch phase assembly voltage element 40b, such that there is no electrical contact between them. Should a suitable (and strong enough) magnetic force be applied to the magnetic switch phase assembly magnet 40e and to the magnetic switch phase assembly voltage element 40b, it will overcome the strength of the magnetic switch phase assembly magnet spring 40f, and the magnetic switch phase assembly voltage element spring 40g, creating a physical contact which enables an electrical current to flow between the magnetic switch phase assembly contact element 40a, and the magnetic switch phase assembly voltage element 40b.

[0215] Magnetic switch phase wire 40j can also be omitted, and the magnetic switch phase assembly voltage element spring 40g can be used as an electrical conductor in its place.

[0216] The magnetic switch phase assembly 40 can have a magnetic switch phase assembly symmetry axis 40l.

[0217] According to another embodiment of the present invention the magnetic switch phase assembly 40 includes no magnetic switch phase assembly magnet 40e and a suitable stronger magnetic force is applied to the magnetic switch phase assembly voltage element 40b, at the proper time.

[0218] FIG. 2d is a partial cut-away side view schematic illustration of an exemplary, illustrative embodiment of a magnetic switch phase assembly 40, according to the present invention.

[0219] The illustration shows force F1 which applies to the magnetic switch phase assembly voltage element 40b, while so long as it is not over powered by an opposite force, there will be no contact between the magnetic switch phase assembly voltage element 40b and magnetic switch phase assembly contact element 40a, and force F2 which applies to the magnetic switch phase assembly magnet 40e, while only applying a stronger force in the opposite direction will enable movement of the magnetic switch phase assembly magnet 40e in the direction of the magnetic switch phase assembly voltage element 40b.

[0220] Despite including the word “phase” in the magnetic switch phase assembly 40 and related components' names, it is to be understood that this is not to limit the use of the present invention to be used with alternating current type of electricity, but it can be used with other types of electricity, such as direct current.

[0292] FIG. 14a is a schematic diagram of a means of supplying DC voltage to at least one planar stationary unit set 101, according to the present invention.

[0293] The mains outlet plug 71 is plugged into an electrical power supply socket (usually a standard wall power outlet) and the AC to DC converter 72 converts the power coming from the outlet (usually 110V/220V AC voltage) to a much lower DC voltage (usually, not more than 20-30V, but could be more or less than that). The planar stationary unit voltage regulator 73 is used to regulate and maintain a constant supply voltage to the at least one planar stationary unit set 101 even under high load currents.

[0295] The planar stationary unit sets 101 (not shown in the present illustration) supply a certain voltage level that may not fit the voltage requirements of the receiving electronic device. Therefore, it is required to regulate the incoming voltage to the appropriate voltage levels using the mobile unit voltage regulator 74.

[0296] FIG. 15 is a top view schematic illustration of an exemplary, illustrative embodiment of an apparatus for transferring electrical power 100, according to the present invention.

[0297] The figure also depicts several dimensions crucial to the safety of the apparatus for transferring electrical power, according to the present invention.

[0298] The apparatus for transferring electrical power 100, according to the embodiment described at the present illustration, includes a planar stationary unit grid 201, which is comprised of a plurality of planar stationary unit sets 101, and a mobile unit set 102, also depicts several dimensions crucial to the safety of the apparatus for transferring electrical power, according to the present invention.

[0299] The embodiment of the mobile unit set 102 in the present illustration is different from other embodiments of the mobile unit set 102 described earlier only in its size and dimensions. The operational principles remain the same.

[0300] Planar stationary unit phase assemblies 10 and mobile unit phase assembly 20 serve in this instance for conducting a positive current, while planar stationary unit zero assemblies 11 and mobile unit zero assembly 21 serve in this instance for conducting a negative current and are set in a non-conductive planar stationary unit plus and minus assembly sets grid body 202a.

[0301] The dimension d3 is the largest cross section width dimension of the planar stationary unit phase assembly 10, and the dimension d1 is the largest cross section width dimension of the planar stationary unit zero assembly 11

[0302] The dimension d2 is the minimal distance of the mobile unit phase assembly 20, and from the mobile unit zero assembly 21 to the mobile unit set body edge 102b.

[0303] The dimension d4 is the distance between the mobile unit phase assembly 20 and the mobile unit zero assembly 21.

[0304] Dimensions d1, d2, d3, and d4 are measured from the top view, as depicted in the present illustration on the sides of the planar stationary unit set 101 and the mobile unit set 102 facing each other in the power transferring condition.

[0305] In order to prevent accidental contact between a live plate in the planar stationary unit grid 201 and a person, there must be sufficient insulation around the mobile unit phase assembly 20 and around the mobile unit zero assembly 21.

[0306] This is achieved by making the non-conductive mobile unit set body 102a large enough to overlap any live plates in the planar stationary unit grid 201. Therefore, the dimension d2 must be larger than each one of the dimensions d1 and d3.

[0307] In order to prevent any shorts between the mobile unit phase assembly 20 and the mobile unit zero assembly 21, the distance d4 between them must be large enough so that no live power plate in the planar stationary unit grid 201 may touch both plates in the mobile unit set 102 simultaneously.

[0308] This is achieved by making the distance d4 between the mobile unit phase assembly 20 and the mobile unit zero assembly 21 larger than d1.

[0309] This description refers to the case where all the dimensions of the planar stationary unit phase assemblies 10, and the planar stationary unit zero assemblies 11 of the planar stationary unit grid 201, are identical to each other.

[0310] The mobile unit set 102 depicts a case where the mobile unit phase assembly 20, is greatly larger than any single planar stationary unit phase assembly 10 and planar stationary unit zero assembly 11.

[0311] In such a case, it is not possible to use the planar stationary unit ground element 12 and the mobile unit ground element 22, as they would cause shorts between one of the contact elements in the mobile unit set 102 contact elements in the planar stationary unit grid 201.

[0312] Such a mobile unit set 102 (compared to a single planar stationary unit set 101) ensures that there will always be at least one planar stationary unit phase assembly 10 under the mobile unit phase assembly 20, and at least one planar stationary unit zero assembly 11 under the mobile unit zero assembly 21, with no regards to the orientation of the mobile unit set 102, on the plane seen in the top view of the present illustration, when placed on the planar stationary unit grid 201.

[0313] Although the invention has been described in conjunction with specific embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, it is intended to embrace all such alternatives, modifications and variations that fall within the spirit and broad scope of the appended claims.
