Publication number: 20180348075Abstract: A power management system and method including a normally-open switch, an on/off circuit, a microprocessor, and at least one sensor to monitor a condition. The on/off circuit includes an on/off control gate-controlled switch device such as a PMOS device for system power, a flip/flop switch to respectively activate and deactivate the on/off control PMOS device, and a transition detection circuit connected to the normally-open switch. A single DC power source establishes a source voltage to power the on/off circuit and the normally-open switch. The transition detection circuit generates an “on” signal when the user initially activates the normally-open switch, and supplies the “on” signal to the flip/flop switch to change it to an “on” state to activate the on/off control PMOS device. While activated, the on/off control PMOS device enables system power from the power source to be provided to at least the sensor and the microprocessor.Type: ApplicationFiled: November 17, 2017Publication date: December 6, 2018Inventors: JORGE RUBINSTEIN, ROBERT M.

Publication number: 20180348077Abstract: A method comprises suspending a measuring element within a fluid and applying measuring power to the measuring element. Radiation loss compensation power is applied to a heating element. The radiation loss compensation power is selected to compensate parasitic radiative heat loss from the measuring element. Heat transfer from the measuring element into the fluid is evaluated and a property of the fluid is derived. A sensor which implements the method uses a resistive measuring element which is electrically connected to an evaluation circuit. The heating element is electrically connected to a power source. A processor receives an input from the evaluation circuit and calculates a property of the fluid while the power source provides radiation loss compensation power to the first heating element.Type: ApplicationFiled: June 1, 2017Publication date: December 6, 2018Inventor: Heinz Plöchinger
