Abstract: A system for wirelessly obtaining physiological data from a subject includes a sensor patch and a separate electronics package. The sensor patch is disposed on and adheres to the subject, and includes a first part of a releasable electrical connector. An electronics package includes a second part of the first releasable electrical connector, which is used to physically and electrically connect the electronics package to the sensor patch. The electronics package includes a flexible substrate, with shells set on this substrate. The shells enclose the electronics. The shells are connected by a flexible circuit board. Analog front end circuitry is placed in one shell, while the wireless transceiver is placed in the other shell.

Abstract: A waste-to-energy cogeneration system is described in various embodiments. The system can convert certain fuel-laden waste to thermal energy and electrical power. In certain embodiments, fuel-laden waste which has not been pre-filtered or pre-treated to remove particulates and water is deposited in the cogeneration system and prepared by the system for combustion in an unmodified diesel engine. The fuel-laden waste can comprise oils, greases and fats from food preparation which are contaminated with water and particulates. Thermal and mechanical energy produced by the engine are utilized to provide thermal energy and electrical power external to the cogeneration system.
