Abstract: The personal safety survival device includes a plurality of elongated inflation members that collectively form a triangular enclosure. The triangular enclosure has an opening at distal ends, which enables an end user to climb into the triangular enclosure. The personal safety survival device includes an auto-inflation system that inflates the triangular enclosure when triggered, and is to be used as a life raft that keeps the end user out of water, and safe from drowning. The auto-inflation system includes a CO2 canister in fluid communication with all the elongated inflation members. Each of the elongated inflation members include a manual inflate nozzle. When deflated, the personal safety survival device is able to be rolled up into a relatively small size, and includes a carrying strap as well as a pull cord.

Abstract: An apparatus and method for canceling variations in the beta for a bipolar junction transistor so that the diode equation can be employed to accurately measure the temperature of the transistor based at least in part on a ratio of two target collector currents and two measurements of the base-emitter voltage of the transistor. If the determined collector current of the transistor is relatively equivalent to one of the first and second target collector currents, the transistor's base-emitter voltage is measured and stored. An analog feedback circuit can be employed to change the determined collector current to be relatively equivalent to the first and second target collector currents. The analog feedback circuit can include an optional sample and hold component to further reduce power consumption and reduce noise. A digital circuit can be employed to change the determined collector current to be relatively equivalent to the first and second target collector currents.
