Abstract:

Provided herein are exemplary embodiments of a weighing device comprising a bladder and a plurality of contact switches printed on the bladder. The bladder comprises a top and a bottom sheet of a suitable non porous material. The contact switches are made by printing a conductive pattern on one side of the bladder and printing conductive elements with leads or traces on the other side of the bladder. The two sides of the bladder are heat sealed together along the periphery of the bladder with the conductive portions facing each other. An inflation port is also formed in the periphery. In operation, the bladder is placed under an individual to be weighed. Next, the bladder is inflated using a gas. Finally, monitoring circuitry coupled to the bladder measures and records the pressure at the time each of the switches open due to the separation of the conductive portions.

US Classification:

607 96

Abstract:

A heating system for a hyperthermia apparatus may include a heater having a plurality of independently controllable heater elements located on one or more surfaces of the heater, and a temperature sensor associated with one or more of the heater elements. Each of the surfaces may be proximate to a reservoir cartridge. The heating system may include a computing device in communication with the temperature sensor. The computing device may be configured to adjust an amount of electrical current to the one or more heater elements associated with the temperature sensor based on a temperature reading received from the temperature sensor.

Abstract:

A presence sensor system includes at least one resilient extending member defining an enclosed sensing volume. The sensing volume includes a fluid therein. A pressure within the sensing volume changes upon application of force to the extending member. The presence sensor system further includes a pressure sensor in fluid connection with the sensing volume, a processor system in communicative connection with the pressure sensor and a communication system in communicative connection with the processor system. In a number of embodiments, the presence sensor system is adapted to determine a pressure threshold associated with onset of presence after being placed in use.

US Classification:

73 2902, 374100, 374121

Abstract:

A method of monitoring a space to determine at least one change in state related to at least one activity includes analyzing an amount of water vapor in the air over time and relating a change in the amount of water vapor in the air over time to the at least one change in state. In a number of embodiments, the at least one change in state is related to a kitchen activity which causes a change in the amount of water vapor in the air. Changes in dew point over time may, for example, are determined. In a number of embodiments, changes in dew point over time are determined by measuring temperature and relative humidity over time and determining dew point from measured temperature and measured relative humidity. Changes in dew point over time may, for example, used to identify or distinguish the activity from a plurality of possible activities associated with the change in state. At least one of change in dew point, change in relative humidity and change in temperature over time may be used (either alone or in any combination thereof) to identify the activity associated with the change in state.

International Classification:

G01L 708
G01L 906

US Classification:

73727

Abstract:

A pressure transducer utilizes a diaphragm made, for example, of ceramic or the like having upper and lower surfaces. One surface of the diaphragm receives an elongated thick film resistor. Circuitry is connected to the resistor for measuring any changes in resistance due to strains or forces applied to the resistor. Pressures applied perpendicularly to the longitudinal direction of elongation of the resistor produces high outputs in the form of changes in resistance which can be used to calculate strains in the longitudinal and transverse directions as well.

International Classification:

F03G 706

US Classification:

60528

Abstract:

An actuator (A) includes a body (10) in which a plurality of chambers or bores (34) are defined. The bores are interconnected at an inner end by an elongated passage (30). A heater element (32) extends along the elongated passage. The elongated passage and the inner portion of each chamber or bore are filled with a polymeric material which expands and flows on heating, preferably undergoing a solid to liquid phase change. Extensible members (12), such as pistons, diaphragms, bellows, or the like, are mounted in the bores or wells. When the heater heats the polymeric material causing it to expand and flow, the extensible elements (12) extend under high force with limited travel. In one embodiment, the extension of the extensible members moves a thrust bearing (B) causing frictionally engageable plates (18, 22) of a friction member assembly (C) to engage.
