Abstract: A transparent pane with a conductive coating extending at least over a part of the transparent pane surface, in particular over a visual field of the transparent pane is described. The conductive coating is electrically connected to at least two strip-shaped bus bars such that after application of a supply voltage, a current flows over a heating field formed by the conductive coating. The conductive coating has an electrical resistance such that upon application of a supply voltage in the range from more than 100 volts to 400 volts, a heating output from the heating field is in the range from 300 watt/m2 to 1000 watt/m2. The at least two strip-shaped bus bars have a maximum width of less than 5 mm and are dimensioned such that a maximum electrical power loss per unit of length is 10 watt/m. Moreover, the at least two strip-shaped bus bars have a specific resistivity ranging from 2 ?ohm·cm to 4 ?ohm·cm.

Abstract: A silicon alignment pin is used to align successive layer of component made in semiconductor chips and/or metallic components to make easier the assembly of devices having a layered structure. The pin is made as a compressible structure which can be squeezed to reduce its outer diameter, have one end fit into a corresponding alignment pocket or cavity defined in a layer of material to be assembled into a layered structure, and then allowed to expand to produce an interference fit with the cavity. The other end can then be inserted into a corresponding cavity defined in a surface of a second layer of material that mates with the first layer. The two layers are in registry when the pin is mated to both. Multiple layers can be assembled to create a multilayer structure. Examples of such devices are presented.

Abstract: Disclosed herein is a motor terminal assembly comprising a terminal case comprising a terminal accommodation portion accommodate a terminal of another component, and a front end portion having a larger horizontal cross-section than a terminal hole so as to be caught by the terminal hole outside a bracket, and a body portion formed beneath the front end portion and having a smaller horizontal cross-section than the terminal hole so as to move in the terminal hole and A part of electrical connection means to be connected to a terminal a busbar terminal, and to be located at inside the terminal case. Consequently, it may be possible to prevent damage to the terminal and more effectively prevent the terminal from being inclined or biased in an initial state in which the terminal is inserted into a terminal hole.

Abstract: A signal transmitter with adjustable signal power includes a housing, a first adjustable metal shielding layer and a circuit board. The first adjustable metal shielding layer is disposed within the housing. The area of the first adjustable metal shielding layer consists of a first shielding area and a first un-shielding area. The first shielding area and the first un-shielding area are adjustable. The circuit board is disposed within the housing, and is located below the first adjustable metal shielding layer. The circuit board is electrically connected with the first adjustable metal shielding layer, and includes a signal emission chip. The signal emission chip is configured for adjusting signal emission power to emit a signal according to the first un-shielding area of the first adjustable metal shielding layer. A message generating system and a signal power adjusting method are disclosed herein as well.

Abstract: The invention relates to a method of rendering telecommunication devices ineffective, by creating a substantially radio frequency radiation-free environment by providing an interference generating pattern (IGP) adjacent to the environment in a position between the environment and a source of radio frequency radiation signals so as to substantially reduce, or interfere with such signals thus preventing typical operation of the wireless telecommunications devices. The IGP is generally one that is non-conductive and is or includes a diffraction grating. The IGP is positioned adjacent the environment between the environment and a source of radio frequency radiation signals. Preferably, the IGP is provided as a support member configured in the shape of a diffraction grating, and includes a paint or coating of a non-conductive material having a high dielectric constant thereon.
