Abstract: An autonomous deployment system is herein for functional utilization in the physical placement and deployment of a heating or thermal mat(s). The system is designed to enhance human productivity and ease deployment of the prior art thermal radiating or generating devices for the removal and or inhibition of accumulation of snow and ice. The deployment system as can be designed to operate autonomously with automatic controls and sensors to control both the thermal system and the technology of controlling a deployment system. The system is well suited to autonomously deploy and retract rolled membranes and or flexible materials out over a flat or sloped surface area. The inherent flexibility of the mat allows it to traverse gently curved surfaces.

Abstract: A control method for a microwave oven equipped with a tray installed in a cooking chamber to rotate a popcorn bag while having a popcorn cooking mode to cook popcorn. During cooking, rotation of the tray is temporarily stopped near the point of time when the popcorn bag is increased in size to a maximum size. Accordingly, problems caused by the fact that the popcorn bag comes into contact with the inner wall surface of the cooking chamber so that it cannot rotate are solved. The popcorn cooking mode is an operation mode to cook a popcorn product with corn grains packed in the popcorn bag in a state in which it is folded at least one time. The rotation of the tray is temporarily stopped near the point of time when the popcorn bag is estimated to achieve its maximum length as a folded portion of the popcorn bag is unfolded.

Abstract: A resistive heater having a doped ceramic heating element embedded either partially or completely within a matrix of undoped ceramic material. The ceramic may be silicon carbide, and the dopant may be nitrogen. Many of the advantages of the present heater stern from the fact that the materials used for the heating elements and the matrix material surrounding those elements have substantially the same coefficient of thermal expansion. In one embodiment, the heater is a monolithic plate that is compact, strong, robust, and low in thermal mass, allowing it to respond quickly to power input variations. The resistive heater may be used in many of the reactors and processing chambers used to fabricate integrated circuits, such as those that deposit epitaxial films, and carry out rapid thermal processing.

Abstract: Information handling system peripherals that use a heating element are protected from catastrophic failure due to overheating by a thermal failsafe associated with the heating element that fails the heating element if excessive temperatures are reached. For instance, the failsafe releases the vacuum from a heating element bulb so that the application of power to the filament of the heating element bulb oxidizes the filament resulting in failure of the filament and ceasing of generation of heat. The failsafe includes a melting agent, such as wax or solder, which seals an opening in the bulb unless a thermal runaway temperature is reached in excess of a desired operating temperature. Alternatively, the failsafe includes an expanding agent, such as a ceramic or a liquid-filled bubble, which releases the vacuum by fracturing an opening in the bulb at the thermal runaway temperature. The thermal runaway temperature is selected to induce failure before catastrophic overheating of the peripheral.

Abstract: A portable compact sauna wherein a user's body is warmed to sweating primarily by direct absorption of infrared radiation. Broad infrared radiation emitters or sources are placed around the inside of a narrow cabinet so as to be in close proximity to various parts of a seated user. Fins spaced apart less than finger-width on the emitters protect the user from contact with elevated temperatures in the emitters. The emitters, which lend themselves to easy cleaning, are heated by electric infrared heaters having a unique design which eliminates extremely-low-frequency (ELF) electromagnetic field (ELF) normally generated by AC energized electrical heater elements, to provide low extremely-low frequency EMF saunas able to utilize conventional-commercial electrical-energy sources. The emitters protect the heaters. Power wires for the heaters are arranged for low ELF EMF emission, too.

Abstract: The present invention relates to methodology of and apparatus for accurately positioning devices for performing endoscopic cannulation, papillotomy and sphincterotomy and similar procedures. The sphincterotome with a steerable or adjustable distal segment of the present invention allows the physician to control the position of the distal tip of the device independently of the endoscope and adjust for inconsistencies in the device and the anatomy. According to one embodiment of the present invention, a threaded portion of a cable assembly cooperates with a torque transmission element and a cog to enable the operator to rotate a cutting wire into a desired position relative to the catheter. Alternate embodiments allow the operator to fix the depth of a needle knife while allowing, if desired, accurate rotational positioning of the associated catheter. Threaded stabilizing elements, pivot elements and a steering wire may be used together or individually to accomplish these features.

Abstract: A grip heater has a tubular insulator that is designed to slip over a handlebar and has two interposed pairs of helical recesses. Each pair of helical recesses is formed by two parallel helical grooves and accommodates a heating element; the heating elements can have different resistances to provide differing degrees of heat when selectively connected to a voltage source. Preferably, the pairs of recesses overlap such that the heating elements reside in alternating grooves and cross over each other. The heating elements can be connected to a common ground to allow replacement of existing three-wire grip heaters. When a common ground is employed, the heating elements are preferably isolated where they cross.
