Abstract: A system for tracking and monitoring at least one item in an environment includes at least one transmitter assigned a unique identification number for the item and attached to the item and at least one receiver for receiving a first data packet which includes the unique identification number from the transmitter. At least one node computer controls the receiver, receives a second data packet which includes said unique identification number and direction-of-travel code from the receiver, and determines a location of the item from the direction-of-travel code. A controller computer controls the node computer, receives the unique identification number and the location of the item from the node computer, and stores the unique identification number and the location of the item. A central computer facility coordinates the controller computer and collects and stores the unique identification number and the location of the item for exportation from the system.

Abstract: A method, system and light source provide concentrated illumination from a multi-fiber optical light guide suitable for use where intense illumination is needed. The light from a plurality of high-intensity light emitting diodes is physically coupled into a corresponding plurality of sub-millimeter diameter optical fibers. The optical fibers are combined with appropriate optics to form a flexible illumination system ideal for the intense illumination of small areas. This method and system are designed for applications such as medicine and dentistry where size, weight, wattage, lifetime, and operating temperature of the light source are important considerations.

Abstract: A system and method is provided for detecting carpal tunnel syndrome in a patient, utilizing a vibratory waveform having a discrete frequency and a variable amplitude. The system includes control circuitry (22) for generating an electrical signal having the discrete frequency and a computer (14), including a memory, for controlling the circuitry (22) to vary the amplitude of the electrical signal and to generate associated amplitude data for storage in the memory. The system also includes a speaker (20) for converting the electrical signal into the vibratory waveform. A finger (34) of the patient rests directly on the cone (32) of the speaker (20), so that the vibratory waveform is applied directly to the finger (34).
