Abstract:
A diagnostic system is described that includes semiconductor diodes, a multiplexer, and waveguide structures to create an output light beam. A lens system directs this beam onto a user's body part containing blood for measurement. A software application processes the measurement data to generate physiological information, operating on a control system that may feature a touchscreen, proximity sensor, and wireless transceiver for transmitting data. A host system receives and stores this wireless data, processes it with control logic (including voice recognition software in some embodiments) to determine the user's status, records the status, and outputs it to one or more remote display devices.

Plain-Language Overview of Independent Claims:

• Claim 1: This claim describes a diagnostic system that uses multiple semiconductor diodes as a light source.

A lens system directs this beam onto a patient's blood-containing body part for measurement. A software application processes this measurement to generate physiological information, running on a control system that can receive voice and manual inputs, and includes a touchscreen, proximity sensor, and wireless transceiver. A host system receives, stores, and processes this wireless data to determine the user's status, records it, and communicates it to remote displays.
