Abstract

In an embodiment, a device to convey wireless signal from one location to another which has a rechargeable power source comprised of a remote high-powered light emitting optical source for power generation, a resident high efficiency solar array for light capture and power generation on said device, and a super-capacitor array for power storage on said device. In one example, the light emitting optical source is a high flux LED picked for optimum wavelength for the solar array. The solar array is a high efficiency solar array. The super-capacitor array is configurable based upon the power requirements of the circuit. The wireless mode of communication could be infrared as shown in the prototype, Bluetooth, or some other wireless standard.

REMOTE INFRARED COMMUNICATION SYSTEM USING OPTICAL POWER SOURCE

FIELD OF THE INVENTION

[0001]               This invention relates generally, to wireless communication systems, and more particularly to, a remote infrared communication system. 

BACKGROUND OF THE INVENTION

[0002]                  There are many applications where it would be useful to wirelessly communicate an amount of data from one location to another.  Communication between the two locations where the receiver has immediate access to power and the transmitter is remote from any accessible power source can be very difficult due to access to power.  An added level of difficulty is operation in low light environment such as a scan room for example, which would generally preclude the use of solar power.

[0003]               Current solutions involve the use of connectors between the two locations for power and data transmissions or using a battery for the source of power at the remote location.  In the case of using connectors, the connectors are unreliable and tend to break down after a certain number of insertions.  In the case of using a battery for power, the battery needs replacement or recharging from time to time, which causes a need for service.

[0004]               As this need increases, a simple communication method with a renewable energy source, which does not require service over the usable life of the product, is very desirable.

DETAILED DESCRIPTION OF THE INVENTION

[0005]    Various embodiments of this invention provide a remote infrared communication system, example, for use in medical imaging.  However, the embodiments are not limited and may be implemented in connection with other wireless data communication systems.   

[0006]     Using a high intensity LED array directed upon a remote array of solar cells, it is possible to charge a super-capacitor network which will then provide power to a low power data monitoring and infrared transmission circuit.  The super-capacitor network is configured to support the power requirements of the circuit and can be recharged hundreds of thousands of cycles without a degradation of performance.  Upon full charge, the super-capacitor can power the circuit for days in a low power mode or for a much shorter time while in data transmission mode.  In the example shown in figure 1, we have used a microprocessor with an embedded oscillator and internal A2D for monitoring the parameters of interest.  The “data out” would then be modulated internally...
