The present disclosure provides a system for regulating a temperature of a portion of an article of furniture, and methods of use thereof. The system may comprise at least one sensor configured to detect a biological signal of a user of the article of furniture. The system may comprise a temperature control device configured to change the temperature of the portion of the article of furniture. The system may comprise a processor configured to (i) designate, while the user is asleep on the article of furniture, a time for the article of furniture to wake up the user based on the biological signal of the user that is detected by the at least one sensor while the user is using the article of furniture, and (ii) change the temperature of the portion of the article of furniture by the temperature control device prior to the time.

A joystick for operating utility vehicles is provided. The joystick has a handle area, and the handle area has a substance-to-substance connection to a support element. At least three conductor elements are arranged on the support element. At least one conductor element is designed as a heating element, one conductor element is designed as a temperature sensor element, and one conductor element is designed as a touch-sensing element.

The present application discloses a heater and a smoking set including the heater. The heater includes: a base, having an inner surface and an outer surface; an infrared radiation layer, formed on the surface of the base; the infrared radiation layer is configured to generate infrared rays and at least heat an aerosol-forming matrix by radiation; a heating body arranged at the periphery of the base, and used to receive electric power from a power supply to generate heat. The heating body is configured to transfer the heat to heat the infrared radiation layer to generate the infrared rays. According to the present application, the infrared radiation layer is heated up by the heating body so that the infrared radiation layer generates infrared radiation to heat the aerosol-forming matrix, thereby reducing the preheating time of the aerosol-forming matrix and improving the user experience.

A holding apparatus including a holding substrate having a first main face on one side in a thickness direction thereof, and a heat generation section which is disposed in the holding substrate and generates heat when energized. The heat generation section includes a plurality of first heating elements arrayed in a planar direction orthogonal to the thickness direction of the holding substrate, and a second heating element disposed on a side toward the first main face in the thickness direction with respect to the plurality of first heating elements. Any one of the plurality of first heating elements is electrically connected to the second heating element in series through a first via extending in the thickness direction within the holding substrate.

A heating pad with a plurality of parallel connected heating circuits that are provided with a temperature control circuit. The parallel connected heating circuits are longitudinally separated from each such that a user may cut or sever the heat mat along predetermined cut points that are indicated on the exterior surface of the heat mat. In this way, the length of the heat mat can be adjusted in the field based on the application by simply cutting the heat mat along a predefined cut point.

A ceramic heater includes a ceramic plate in which inner circumferential side and outer circumferential side resistance heating elements are built in; and a cylindrical shaft joined to a rear surface of the ceramic plate. The long hole extends from a start point of the ceramic plate to a terminal position of the outer circumferential portion of the ceramic plate. The entrance portion of the long hole is a long groove. The long groove is provided to extend from the start point to an extended area. Terminals are provided at positions other than the long groove and in a shaft inside area.

A solid state heater and methods of manufacturing the heater is disclosed. The heater comprises a unitary component that includes portions that are graphite and other portions that are silicon carbide. Current is conducted through the graphite portion of the unitary structure between two or more terminals. The silicon carbide does not conduct electricity, but is effective at conducting the heat throughout the unitary component. In certain embodiments, chemical vapor conversion (CVC) is used to create the solid state heater. If desired, a coating may be applied to the unitary component to protect it from a harsh environment.

A transparent display system includes a transparent display, a touch-sensitive layer, and a heater layer. The touch-sensitive layer is connected to the transparent display and is configured to detect a touch-based input to the transparent display. The heater layer is connected to the transparent display and includes a trace array and one or more electrodes operable to activate the trace array to generate heat to heat at least a portion of the transparent display based on the touch-based input.

This present disclosure relates to a flexible heating device having a unique layered assembly structure including a flexible heat generating layer. The present disclosure also relates to a method of manufacturing the flexible heating device and method of use of the flexible heating device in various applications.
