A thermostat is configured for automated compatibility with HVAC systems that are either single-HVAC-transformer systems or dual-HVAC-transformer systems. The compatibility is automated in that a manual jumper installation is not required for adaptation to either single-HVAC-transformer systems or dual-HVAC-transformer systems. The thermostat has a plurality of HVAC wire connectors including a first call relay wire connector, a first power return wire connector, a second call relay wire connector, and a second power return wire connector. The thermostat is configured such that if the first and second external wires have been inserted into the first and second power return wire connectors, respectively, then the first and second power return wire connectors are electrically isolated from each other. Otherwise, the first and second power return wire connectors are electrically shorted together.

A wafer level chip size package (WLCSP) and a method of manufacturing the same are disclosed. Lands are formed at the ends of redistribution layers. The redistribution layers excluding the lands and a first dielectric layer are covered with a second dielectric layer. After forming a first under bump metallurgy (UBM) layer on the land, a solder ball is reflowed to the first UBM layer. A second UBM layer is widely formed on the entire second dielectric layer that is the outer circumference of the first UBM layer and is connected to the redistribution layer through a via-hole. Therefore, the second UBM layer having a large area can be used as a ground plane or a power plane. In addition, the second UBM layer can electrically connect the redistribution layers physically separated from each other. Therefore, the plurality of redistribution layers can cross each other without being electrically shorted with each other.

A cooling device for a heat-generating electronic component such as a semiconductor integrated circuit element is provided. In particular, a cooling device using a thermoelectric conversion material is provided. A cooling device for an electronic component includes a thermoelectric conversion material disposed between two electrodes that function as a cathode and an anode and are electrically short-circuited. The thermoelectric conversion material is either a p-type material or an n-type material or a combination of p-type and n-type materials arranged alternately in series. This cooling device is brought into contact with an electronic component requiring cooling so that one electrode side in contact with the thermoelectric conversion material becomes a low-temperature side and the other electrode side becomes a high-temperature side. A temperature difference between the two electrodes causes the thermoelectric conversion material to produce a thermoelectromotive force which generates current to cool the high-temperature side.

Provided are a nano-scale LED assembly and a method for manufacturing the same. First, a nano-scale LED device that is independently manufactured may be aligned and connected to two electrodes different from each other to solve a limitation in which a nano-scale LED device having a nano unit is coupled to two electrodes different from each other in a stand-up state. Also, since the LED device and the electrodes are disposed on the same plane, light extraction efficiency of the LED device may be improved. Furthermore, the number of nano-scale LED devices may be adjusted. Second, since the nano-scale LED device does not stand up to be three-dimensionally coupled to upper and lower electrodes, but lies to be coupled to two electrodes different from each other on the same plane, the light extraction efficiency may be very improved. Also, since a separate layer is formed on a surface of the LED device to prevent the LED device and the electrode from being electrically short-circuited, defects of the LED electrode assembly may be minimized. Also, in preparation for the occurrence of the very rare defects of the LED device, the plurality of LED devices may be connected to the electrode to maintain the original function of the nano-scale LED electrode assembly.

A three-dimensional printing technique can be used to form a microphone package. The microphone package can include a housing having a first side and a second side opposite the first side. A first electrical lead can be formed on an outer surface on the first side of the housing. A second electrical lead can be formed on an outer surface on the second side of the housing. The first electrical lead and the second electrical lead may be electrically shorted to one another. Further, vertical and horizontal conductors can be monolithically integrated within the housing.

The present invention prevents breakage of a gate insulating film of a MOS device and provides a nitride semiconductor device having improved reliability. An SBD metal electrode provided between a drain electrode and a gate electrode is configured to form a Schottky junction with an AlGaN layer. Further, the SBD metal electrode and a source electrode are connected and electrically short-circuited. Consequently, when an off signal is inputted to the gate electrode, a MOSFET part is turned off and the drain-side voltage of the MOSFET part becomes close to the drain electrode voltage. When the drain electrode voltage increases, the SBD metal electrode voltage becomes lower than the drain-side voltage of the MOSFET part, thus the drain side of the MOSFET part and the drain electrode are electrically disconnected by the SBD metal electrode.

A shorting clip terminal connector assembly electrically shorts together terminals in a first connector body dependent on connection status of a first and a second connector body. A shorting clip terminal disposed in a shorting clip terminal cavity in the first connector body receives a protrusion disposed on the second connector body. When the second connector body is mated with the first connector body, the protrusion engages a lift element of the shorting clip terminal in the shorting clip terminal cavity thereon and urges the lift element to lift contact elements of the shorting clip terminal away from the terminals in the shorting clip terminal cavity enabling insertion of protrusion side walls intermediate the contact elements and the terminals in the shorting clip terminal cavity. The contact elements of the shorting clip terminal do not make electrical contact with the terminals and the protrusion side walls further shield the contact elements from making electrical contact with the terminals.

There is provided a small multi-band antenna that is capable of supporting multiple bands. A first sub-element (11) is disposed at a region where strength of electric field becomes relatively large while power is being fed on a main element (10) capable of irradiating a high-frequency signal of a plurality of frequency bands, and a second sub-element (12) is disposed at a region in which strength of electric field becomes relatively small while power is being fed on the main element (10). Then, the first and second sub-elements (11) and (12) are operated as passive reflective elements by putting one end portions of the first and second sub-elements (11) and (12) into an electrically open state by inputting a control signal of a first level to a switching mechanism (14), and are operated as electrically short-circuit elements that couple in high frequency with the main element (10) by grounding one end portions directly or via a predetermined resonance circuit by inputting the control signal of a second level. Thus, the high-frequency signal irradiated from the main element (10) is switched to any one of the plurality of frequency bands.

The contact is installed in a through aperture in a dielectric panel such that the contact points extend from opposed openings of the aperture. Optionally, the aperture is filled with a compliant, conductive elastomer.
