[0002] 1. Field of the Invention

[0003] The invention relates to an electrical appliance equipped with a redundant battery enabled by a main power supply to charge standby cells, featuring convenience of operation at reduced cost.

[0004] 2. Description of the Prior Art

[0005] With most wireless peripheral or control means, such as, a wireless computer mouse, cordless trackball, cordless keyboard, or cordless telephone set for indoor use, it is standard practice to have them equipped with a primary cell, a secondary rechargeable cell or super capacitor, or similar energy storage means to drive associated circuits, and to eventually transmit signals to receivers, in one-way, i.e., simplex, or two-way, i.e., duplex mode of operations.

[0006] A drawback of the above-mentioned cordless peripheral installation is that due to gross power consumption, charging or replacement of cells is often required, which is especially annoying when the unit is suspended or on stand by for charging to functionable power. A computer, information-enriched household electric appliance, indoor cordless telephone set, or the main unit of an electric appliance is equipped with a reception circuit which drives a reception device, or a two-way transceiver device or has an A.C. or D.C. power supply which drives other interface devices. The power can be provided by the main power supply to a computer, information-enriched electric appliance, indoor cordless telephone set or electric appliance, or alternatively, indirectly from wired peripheral devices powered by the main power supply, such as a receiver or a keyboard or other wired peripheral device. The power source is connected to a power supply interface which supplies the load with power and, as an additional feature, charges one or more sets of batteries through ports PO in or on the main unit of a computer, information-enriched household electric appliance, indoor cordless telephone, other electric appliance, or notebook computer or monitor; or alternatively, in the form of one or more sets of redundant rechargeable batteries and ports P0′ installed on a wired peripheral device such as a keyboard or receiver set attached to a cord assembly, or in the form of one or more sets of redundant rechargeable batteries and ports P0′ on cordless peripheral equipment, wherein the power source is the main power supply.

[0007] The redundant battery and port P0′ for charging purposes according to the invention may be installed as a redundant set on the casing, receiver, keyboard, or other wired peripheral device associated with an electric appliance, or in or on a computer unit, an information-enriched household electric appliance, an indoor cordless telephone set, or installed into a cordless peripheral so that the main power supply can be supplied with low voltage D.C. or be in an A.C. line voltage which converts to a D.C. source through transformation and rectification to feed a redundant battery through a port P0′, or peripheral circuit. Power is provided to one or more sets of redundant batteries for charging purposes through a port P0′, which optionally resides in or on the main casing, monitor or receiver, so as to charge in turn the redundant energy storage device ESD101′ which consists of a secondary cell or super capacitor coupled thereto. The main power supply may further be coupled to a power supply interface serving as input to the cordless peripheral via the power supply output interface, to regulate the charging voltage and charging with respect to the energy storage device ESD101 in a cordless peripheral device, as well as actuation of control in the cordless peripheral device, or actuation of the emission circuit T101 or two-way transceiver RT101. Furthermore, the same battery and port P0′, of the one or more sets serves as redundant equipment for charging purposes. When required, the battery serves as an redundant energy storage device ESD101′.

[0028] As shown in FIG. 1, a block diagram of the circuit illustrates the preferred embodiment of the invention in the form of a redundant battery which connects to a main power supply and supplies an electric appliance with power not shown in the drawing, comprising:

[0029] A receiver circuit REC101 comprises an R.F., infrared or ultrasonic receiving circuit which further is comprised of solid-state electronic elements or electromechanical components to receive manually controlled or audio or video signals. The circuit REC101 is installed onto a receiver casing H101, i.e., the main casing of a computer, information-enriched household electric appliance, indoor cordless telephone set, electric appliance, a monitor unit, a notebook computer or a peripheral device such as keyboard. Once the computer or electric appliance accesses power by way of cord set CB100, the receiver circuit RC101 becomes a source of power to the one or more sets of redundant batteries and port P0′ for charging purposes, located within the receiver casing H101 and to the receiver itself. The received signal may be transferred to the main unit via cord set CB100, where the cordless interface is a two-way duplex mode. This receiver circuit REC101 may be replaced with a two-way transceiver RT101, where the main power supply is an A.C. system. The receiver circuit may be equipped with a converter for rectification of A.C. into D.C. to drive the receiver circuit and to serve as a source of charging power to the redundant battery through port P0′, or for feeding to the power output interface PS101.

[0030] A cord set CB100 is furnished between the power supply to a receiver, a main computer unit, an information-enriched household electric appliance, an indoor cordless telephone set or a monitor. For example, the cord set can include socket/plug sets of PS2, USB, IEEE1394 or other chosen interface specification to connect the power supply to the main computer unit, information-enriched electric appliance, indoor cordless telephone or monitor unit, or for direct connection inside a casing in symbiotic relation with the devices, so as to transmit signals and to supply the power needed to empower the redundant battery through port P0′ in the casing of a computer, other electric appliance or monitor, or other cord-bearing peripheral and relevant circuit.

[0031] A power output interface PS101 is composed of an electric power transmission means and installed onto an independently provided receiver casing, where the receiver is in a symbiotic relationship with the main unit or peripheral device. The interface may be installed on the main casing unit or on the casing of a monitor, a receiver or other peripheral device. The power output interface PS101 is preferably a like-electrode-on-like-electrode coupling with a power input interface PS102 on a cordless peripheral, whereby energy on the main unit is transferred to electric energy storage unit ESD101 in the cordless peripheral.

[0032] A power input interface PS102, in the form of an electric power transmitter composed of conductive contacts or a plug/socket assembly, couples the like-electrode couplings with the power output interface PS101 on the main unit casing, the monitor, the receiver or other peripheral, whereby the electrical energy delivered to the main unit is transferred to the electric energy storage ESD101 in the cordless peripheral or in the redundant electric energy storage ESD101.

[0035] 2. A means to transmit electric energy comprising means to superpose the power output interface PS101 with the power input interface PS102;

[0036] 3. A means to transmit electric energy by interposition of a supplemental magnet between the power input interface PS102 and the power output interface PS101;

[0037] 4. A means to transmit electric energy by mounting electromagnetically conductive contacts between the power output interface PS101 and the power input interface PS102;

[0039] 6. A means to optionally charge by the furnishing a power cord interposed between the power output interface PS101 and the power input interface PS102. The power cord and its corresponding plug/socket assembly can be removed, stowed away or wound inside the casing;

[0040] 7. A polarity error-proofing means permitting mutual coupling destined for the transmission of electric energy between the power output interface PS101 and the power input interface PS102, featuring:

[0041] (A) a series connection of a reverse isolation diode in the power supply circuit; or

[0042] (B) a polarity error-proofing geometry in the conductive contacts or plug/socket assembly; or

[0043] (C) a supplemental magnet sub-assembly in the conductive contacts or plug/socket assembly between the power output interface PS101 and the power input interface PS102, such that mutual attraction will result when coupling of the correct polarity is made between the output side and the input side of the power supply, but mutual repulsion would ensue if the coupling is unmatched due to a polarity error, thus achieving a polarity error detection effect.

[0044] A receiver casing H101 can be either independent or integral with the main casing unit, monitor or other peripheral, which houses the receiver circuit REC101 or two-way transceiver RT101. The receiver casing H101 is furnished with one or more sets of redundant batteries and ports P0′ for charging purposes, fitted with conductive contacts C101, C102, or a power supply plug/socket assembly, or adapted for power cord storage and may be concurrently furnished with an extension hub.

Where the cordless interface features two-way transmission/receiving capabilities, the peripheral circuit T101 may be replaced by a two-way transmission/receiving device RT101.

[0046] A cordless peripheral casing H102 is in the form of an independent housing complete with R.F., infrared or ultrasonic transmitting keyboard, mouse, trackball or other cordless peripheral devices.

There may be provided one or more sets of redundant batteries and ports P0′ for charging purposes, to be incorporated into relevant circuit structure in a redundant energy storage ESD101′ for the secondary cell or super capacitor. On the casing may be mounted a power input interface PS102 which consists of a plug/socket assembly or of conductive contacts C101′, C102′. There may be provided a power control REG101, or a redundant power control REG101′ specifically for power storage ESD101 or redundant power storage ESD101′ or for both in common service. The power storage ESD101 and redundant power storage ESD101′ are provided where needed. Power control REG101 or redundant power control REG101′ controls electric power coming from power output interface PS101, for the purpose of charging the power storage ESD101 or redundant power storage ESD101′.

To control the electric power that is fed to the power input interface PS102 on the cordless peripheral device, an illuminated display of the condition of charging control by current restriction or voltage restriction with respect to the energy storage ESD101 or redundant energy storage ESD101′ is included.

[0048] Any of the electric appliances defined in the foregoing is furnished with a redundant battery that is fed by a main power supply. The power control circuit, in addition to yielding control, regulation and display performances by means of conventional technique such as linear analogue circuit or wave interception circuit(PWM), may be executed by a series connection with zener diodes, or with any other diode having a zener effect and photo-emitting effect at the same time, so-called light-emitting diode to achieve in concurrent voltage degrading and display of current transmission state at the same time. The circuits below are examples featuring convenience at reduced cost.

Multiple sets of the electric energy storage ESD101 and the redundant electric energy storage ESD101′ are in series with the available power control REG101 and the redundant power control REG101′ before being placed in parallel across the D.C. charging power supply. The power control device is composed of a light-emitting diode LED101 (including one or more in series or in parallel) in forward series with the D.C. power source which produces a voltage degrading or light emission capability, as reflected in a charging condition. Optionally, a series connection with a current limiting resistor R101, may be chosen to protect from short circuits. Also, a forward series connection of an isolation diode CR101 is another option to prevent back flow.

In this instance, the zener diode is in series with the output terminal, and the voltage of the zener diode is taken as the level of the voltage degradation between the power source and the output interface. Optionally, a charging state display circuit comprising a photo-emitting diode LED102 and a current limiting resistor R102 connected in series may be in parallel across the output terminals.

The redundant battery and port P0′ receives power through the signal cord S100 on the main unit BS101, or from an auxiliary power supply PS200, which is a D.C. source of low rating voltage D.C. which is converted from line voltage. This is regulated by the redundant power control REG101′ to account for a source of power with which to enable the redundant battery and port P0′, and to provide randomized charging of redundant energy storage means ESD101′ on the main unit BS101 of the cordless phone or on a cordless hand-held cellular handset HY101. The main unit or handset may be installed with one or more sets of redundant batteries and ports P0′ for charging purposes, into which is to be loaded a redundant energy storage means ESD101′ serving both to charge and to discharge when needed;

[0068] (8) installed in the casing of a household cord-bearing phone set, shown in FIG. 20. Because for the need of multiple functions in cord-bearing telephone sets, certain models already have been provided with auxiliary power sources. In this case, the power supply of the main unit BS102 signal line S100 or an auxiliary power source PS200 of low voltage D.C. converted from line voltage may account for the power needed for charging purposes to the redundant battery or adaptor P0′ for charging purposes, in which case, randomized charging is made possible with respect to the redundant energy storage means ESD101′ as arranged, to the main unit BS102 or hand-held handset and assembly HY102 of a cord-bearing phone set and furthermore, may be provided where appropriate, one or more sets of redundant batteries and ports P0′ for charging purposes, into which is to be installed redundant energy storage means ESD101′ meant to charge and discharge when needed;

[0069] (9) it and the redundant energy storage means ESD101′ deployed in order may be any two or more of the devices or means, or arrangements disclosed in items 1 through 8 in this paragraph herein before.
