Description
Field of the Invention
The present invention relates generally to containers and more particularly to a container for transporting, handling, and storing sensitive items wherein the environment of the container is monitored and recorded such that data regarding desired parameters relating to the environment may later be recalled.
Background of the Invention
Specialized containers for transporting, handling, and storing sensitive items are known. Such containers typically utilize durable outside shells, cushioned inner supports for the stowed sensitive items, and sealed openings to prevent the undesirable introduction of moisture. Cushioned external supports, i.e. air bags, as well as thermal insulation may likewise be utilized, when desired.
It is also known to individually monitor selected environmental parameters such as shock, temperature, and humidity so as to provide an indication of the levels of such parameters to which the stowed sensitive item is exposed. The monitoring of such parameters is accomplished utilizing dedicated separate autonomous monitoring devices.
The use of such dedicated separate autonomous monitoring devices requires that separate power sources, sensors, and recording means be provided for each device. As such, considerable redundancy in the hardware required for such monitoring exists.
Additionally, such dedicated separate devices must be individually installed, maintained, and read. Thus, use of such dedicated individual monitoring devices is comparatively complex and time intensive.
Additionally, it is known to seal containers housing critical or sensitive items so as to provide an indication that the container has been opened. Particularly, opening by unauthorized personnel can likewise be revealed, since authorized personnel typically are capable of resealing the container. However, no indication of the number of times that the container has been opened, either by authorized or unauthorized personnel, is provided.
As such, it would be beneficial to provide an easy to use, low maintenance, monitoring system for providing desired information regarding a variety of different environmental parameters and also indicating the number of times that the container has been opened, both by authorized and unauthorized personnel.
Summary of the Invention
The present invention specifically addresses and alleviates the above-mentioned deficiencies associated with the prior art. More particularly, the present invention comprises a container for transporting, storing, and handling sensitive items. The container comprises a housing within which at least one sensitive item is stowable and a monitoring system for monitoring a plurality of separate parameters to which the sensitive items are sensitive. The monitoring system records and provides data regarding the parameters to which the sensitive item is sensitive.
The monitoring system monitors a variety of different environmental parameters such as vibration, shock, temperature, humidity, magnetic field strength, unauthorized opening of the container, and attitude of the container.
Optionally, a display may be utilized to provide the data regarding the parameters to which the sensitive item is sensitive. The monitor may optionally additionally provide warning messages and/or instructions when the monitoring system receives an indication that an environmental parameter has exceeded a predetermined value.
For example, such warning messages may comprise messages indicating that a particular environmental parameter has been exceeded and that the contents of the container may no longer be usable or may require rework. Instructions may also be provided so as to mitigate further damage to the sensitive items housed within the container, provide information necessary for rework, or provide information on whom to contact or inform of the situation. Those skilled in the art will recognize that a variety of such messages, dependent upon the particular sensitive item being stowed within the container and the nature of the environmental parameter whose preset value is exceeded, are likewise suitable.
The housing preferably comprises a plurality of partitions defining a plurality of cells within which the sensitive items are stowable. The monitoring system preferably individually monitors each of the cells. Optionally, each cell may be individually configured such that the monitoring system monitors only desired environmental parameters therein. Thus, each cell of the container may be customized for containing a particular sensitive item.
The partitions preferably define inner and outer cells, the inner cells being configured to receive the sensitive items and the outer cells substantially containing the monitoring system.
The monitoring system preferably comprises a microprocessor, a memory, a self-contained power source such as a battery, a clock, and a plurality of sensors interconnected with the microprocessor. The sensors preferably comprise a vibration sensor, a shock sensor, a temperature sensor, a humidity sensor, a magnetic field sensor, an unauthorized opening sensor, and an attitude sensor. Those skilled in the art will recognize that various other sensors are likewise suitable, depending upon the particular desired environmental parameters to the monitor.
The monitoring system preferably comprises a port for downloading instructions regarding the parameters to be monitored. For example, a list of the individual parameters to be monitored, the preset levels for triggering messages, and the messages to be displayed could be downloaded from a host computer to the monitoring system via the port.
The port may optionally also be utilized for uploading the results of monitoring the environmental parameters. Thus, the results of the monitoring process may be uploaded to a host computer, then analyzed and/or a report prepared by the hose computer indicating the results of the monitoring process.
Thus, in use, sensitive items within a container are monitored during transport, storage, and handling thereof via a monitoring system which monitors a plurality of sensors which in turn sense parameters to which the sensitive components are sensitive. Data received from the individual sensors is recorded and provided for later display, uploading, etc.
Items having differing environmental criteria may be stored within different portions or cells of the container wherein the different individual cells of the container are environmental monitored accordingly. For example, a component particularly sensitive to temperature would be stored in a cell wherein temperature is monitored and a component particularly sensitive to shock would similarly be stored in a cell wherein shock is monitored. Those skilled in the art will recognize that various different combinations of sensors may thus be utilized in various different cells, as desired.
These, as well as other advantages of the present invention will be more apparent from the following description and drawings. It is understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.
