| 20090041085 | Temperature responsive systems - A shape memory material activated device of the present invention uses a shape memory material activator to create a path through a shell wall of the device. The path through the shell wall may release a substance contained in the shell or allow a substance to enter the shell. The path may be created by fracturing, puncturing, exploding, imploding, peeling, tearing, stretching, separating, debonding, abrading or otherwise opening the shell and, may be permanent or reversible. The substance may be released in one location while the device is stationary or along a path while it is traveling, self-powered by the shape memory material activator. In addition, the substance may be delivered to an object upon contact with its surface. The self powering abilities allow these devices to be used as substance delivery devices as well as actuators, transporters, and energy conversion systems with modular characteristics and growth potential. The devices may be armed, prior to the beginning of their service life, to be placed in a state of readiness to release their substances once the path is created. Prior to arming they may be maintained at any temperature, incapable of releasing their substances. The devices according to the present invention may be used as temperature sensors or warning devices, drug delivery devices, and the like. | 02-12-2009 |

| 20120076172 | MICRO-ELECTRO-MECHANICAL-SYSTEM TEMPERATURE SENSOR - The present invention provides a micro-electro-mechanical-system (MEMS) temperature sensor that employs a suspended spiral comprising a material with a positive coefficient of thermal expansion. The thermal expansion of the suspended spiral is guided to by a set of guideposts to provide a linear movement of the free end of the suspended spiral, which is converted to an electrical signal by a set of conductive rotor azimuthal fins that are interdigitated with a set of conductive stator azimuthal fins by measuring the amount of capacitive coupling therebetween. Real time temperature may thus be measured through the in-situ measurement of the capacitive coupling. Optionally, the MEMS temperature sensor may have a ratchet and a pawl to enable ex-situ measurement. | 03-29-2012 |
| 20140177675 | HEAT DETECTOR WITH SHAPE METAL ALLOY ELEMENT - A temperature sensing system comprises a conductive tube, a shape memory alloy (SMA) element, and a detector.

| 20140334526 | TEMPERATURE-SENSITIVE LABEL - A temperature-sensitive label is described. The temperature-sensitive label has a temperature-sensitive system having a filiform shape memory member that has a first end portion having a terminal part fixedly secured to a first contact member, a second end portion having a terminal part restrained by a second contact member in a non-permanent way, and a central curved portion. The central curved portion is in the martensitic phase while the first and second portions are in the austenitic phase at a same environmental temperature above a critical threshold temperature to be monitored by the label such that in case of exposure to a temperature lower than the preset critical threshold temperature the end portions of the filiform shape member perform a phase transition, from austenitic phase to martensitic phase, which causes its irreversible disengagement from the restraint formed by the second contact member. The disengagement condition is optionally visible, for example, through a transparent window and/or monitored by an RFID system. | 11-13-2014 |

| 20090041086 | Furnace temperature monitoring device and method - A method for measuring the temperature at various locations in a furnace adapted to heat-treat a metal part commences by placing one or more devices at various location within the furnace. Each device is an inorganic/metallic skeletal structure residual from firing a mixture of binder and one or more of inorganic or metallic particles at a temperature that chars the binder to form the inorganic/metallic skeletal structure of a determined shape. A physical parameter of the skeletal structure determined shape is monitored after firing of the furnace. Then, the monitored physical parameter is compared to a plot of temperature versus the physical parameter to determine the temperature of the furnace at the various locations. | 02-12-2009 |

| 20130128924 | GAS-ACTUATED THERMOMETER - The gas-actuated thermometer is formed as a unitary, monolithic glass structure with a gas bulb at one end and an indicator tube extending therefrom. The bulb and tube are permanently and hermetically sealed to contain the actuating gas therein. A closed cell foam indicator resides in the indicator tube. The indicator travels along the tube in accordance with the expansion and contraction of the gas within the bulb and adjacent portion of the tube. A second gas or mechanical spring is provided in the opposite end of the tube to balance the pressure of the indicator gas. The indicator tube, and preferably also the bulb, are flattened to an elliptical or similar cross-sectional shape. This facilitates the fit of the device for use as an oral medical thermometer, and the wider cross section enables both Celsius and Fahrenheit temperature scales to be marked along the indicator tube. | 05-23-2013 |
