The invention relates to a ceramic cooling and heating body for controlling the temperature of components, wherein the cooling and heating body consists of a plate-shaped support with a front side, an opposite rear side and side faces connecting the front side to the rear side, and metallizations, connected to the support, are arranged on the front side and/or the rear side, and the support has cooling elements. In order to be able to control the temperature of any electrical or electronic component, it is proposed according to the invention that a heating structure is affixed to the front side and/or the rear side.

A wax warmer includes a reservoir for receiving a wax melt, a housing defining an interior volume and configured to receive the reservoir, and a hermetically sealed heater engine positioned within the interior volume and in thermal contact with the reservoir.

A method for manufacturing an electrostatic chuck with multiple chucking electrodes made of ceramic pieces using metallic aluminum as the joining. The aluminum may be placed between two pieces and the assembly may be heated in the range of 770 C to 1200 C. The joining atmosphere may be non-oxygenated. After joining the exclusions in the electrode pattern may be machined by also machining through one of the plate layers. The machined exclusion slots may then be filled with epoxy or other material. An electrostatic chuck or other structure manufactured according to such methods.

An electric heating device includes a control portion adapted to control electric energy supplied to a heater, based on a before-heating temperature, which is a temperature of at least one of an object, the heater and a heat dissipation portion before the heater generates heat, the control portion is adapted to calculate the temperature of the object, based on the before-heating temperature and the electric energy supplied to the heater.

A wearable thermoregulation device, system, and method. A thermoelectric device is configured to controllably heat and cool a control surface. A power source is configured to provide power to operate the thermoelectric device. A wireless communications and control module is configured to wirelessly send and receive signals, and to control the thermoelectric device. A carrier structure carries the thermoelectric device, the power source, and the wireless communications and control module, and is configured to be removably carried on the body of a user such that the heated and cooled control surface is in direct contact with the user's skin.

Disclosed herein are methods for controlling light fixtures comprising unique color light sources with independently controllable luminous flux, comprising controlling a luminous flux of each of the light sources, wherein a spectral distribution of light emitted from the light sources upon being controlled according to settings within a plurality of setting is different between settings, and a color of light emitted from the light sources is similar or identical between settings. The methods may improve color rendering where a certain color of emitted light is required, e.g., where a certain prop or costume is better illuminated with one setting compared to another setting, drawing attention to certain objects in a scene, e.g., by choosing a setting which makes a certain object stand out, and/or providing an intriguing optical effect, e.g., by shifting between settings, which makes certain objects appear to change color while others appear to keep same color.
