Patent number: 8128282Abstract: A microsystem component with a device (3) deformable under the influence of temperature changes is disclosed. The device comprises at least one first (4, 5) and second (8) element with differing thermal expansion coefficients and different thermal conductivities.

Publication number: 20100040113Abstract: A sensing system, sensing method, and method of producing a sensing system capable of providing a cumulative measurement capability, such as in the form of a RFID tag capable of measuring cumulative heat and humidity for continuous monitoring of storage and shipping conditions of various goods. The system includes integrated circuitry and a plurality of sensing elements, preferably having cantilevered bimorph beams. Each sensing element is responsive to an environmental condition so as to deflect toward and away from open contacts in response to changes in the environmental condition. Each sensing element produces a digital output when it contacts and closes its open contacts. The integrated circuitry interfaces with the sensing elements so that the digital outputs of the sensing elements are processed to generate a system output of the sensing system.Type: ApplicationFiled: October 8, 2009Publication date: February 18, 2010Applicant: EVIGIA SYSTEMS, INC.Inventor: Navid Yazdi

Patent number: 5215378Abstract: A dual temperature indicator providing visual indications when exposed to predetermined high or low temperatures. The indicator has a bulb with a capillary tube and an attached high temperature indicator structure. The bulb has a first liquid which also fills a predetermined portion of the tube. A separating substance and a second miscible liquid further fills a predetermined portion of the remainder of the tube. At a predetermined low temperature, the liquid in the bulb contracts causing the separating substance and a portion of the second liquid to move into the bulb to produce a visible color change. The high temperature indicator structure has an indicating member in contact with the capillary tube end and which provides a visual indication at a predetermined high temperature when the liquids expand upon an environmental temperature increase.Type: GrantFiled: April 17, 1992Date of Patent: June 1, 1993Assignee: Introtech, Inc.Inventor: Wendell J. Manske

Patent number: 4994780Abstract: An extended resistance temperature sensor formed of a plurality of lengths of pre-insulated resistance temperature detector (RTD) wire. The RTD wire is either unheated, self heated or is heated by means of strands of heater wire integrated with or placed closely adjacent to the RTD wire. The RTD wire itself, or together with the heater wire, is bonded together in one embodiment. Alternatively the RTD wire, or with the heater wire, may be encased in insulated shrink tubing, thin wall metal tubing or both. Connectors are provided to supply electrical current for heating purposes or to connect the RTD wire to detection circuitry, or both. Protective sheaths are provided over the connectors.Type: GrantFiled: May 2, 1988Date of Patent: February 19, 1991Assignee: Fluid Components, Inc.Inventor: Malcolm M. McQueen

Patent number: 4738706Abstract: The device comprises a three-dimensional grid of thermocouples which are immersed in a fluid, which is moving in a covered channel and has a temperature above that of its environment. Apertures in the sheathing of the channel can be progressively closed by shutters so as to control the cooling of the fluid through an outgoing radiation through the apertures. Burners with a variable intensity are placed within the channel and allow to heat up the fluid in the vicinity of each burner. The position of each shutter and the fuel flow to each burner are commanded severally, based on the values emitted by the ensemable of the thermocouples in order to obtain a homogeneous repartition of the temperature of the fluid, transversally with respect to the channel.Type: GrantFiled: August 13, 1986Date of Patent: April 19, 1988Assignee: Glass Advanced Technology CorporationInventor: Vittorio Picinelli

Patent number: 4415279Abstract: A method and a meter for measuring the quantity of heat abstracted from a circulating flow of liquid by a consumption unit. Indirect measurement of the volume flow rate of the liquid is made, while maintaining a sub heat flow (Q shunt) from or to the main heat flow transported by the flow of liquid and measuring the temperature at some points by means of temperature sensors (4). The volume flow rate of the flow of liquid is determined on the basis of the flow rate dependent heat transfer in the boundary layer (7) of the flow of liquid at the location, where the sub heat flow (Q shunt) leaves or enters, by determining the temperature differential (.DELTA.T.sub.i,b) across the boundary layer, and the sub heat flow (Q shunt) passing through said boundary layer (7). At least one absolute temperature of the flow of liquid is measured for correcting the temperature dependency of the material constants of the liquid involved in said determination of the volume flow rate.Type: GrantFiled: November 17, 1980Date of Patent: November 15, 1983Assignee: N.V.

Patent number: 4359637Abstract: With the heretofore known monitoring systems the parameters or magnitudes to be monitored are converted into electrical signals and transmitted, by means of electrical lines or conductors, to a central station. Because electrical signal transmitters are undesired, particularly in explosion endangered atmospheres or surroundings and, further, since spurious signals can be induced in electrical signal lines, proposals have already been made to utilize monitoring apparatuses working with optical signal conductors. The different embodiments of feelers of the invention, for optical monitoring apparatuses, enable monitoring the continuous change and/or exceeding a predetermined threshold, of electrical, mechanical and thermal parameters or the like.Type: GrantFiled: April 14, 1980Date of Patent: November 16, 1982Inventor: Benno Perren
