Abstract: A connector for electrically connecting to conductive structures formed on a semiconductor device includes a core including an isolation layer and signal vias and ground vias formed in the isolation layer; a first ground plane formed on a surface of or in the core and electrically connected to the ground vias; a first set of contact elements formed on a first surface of the core and electrically connected to the signal vias to form signal pins; a second set of contact elements formed on the first surface and electrically connected to a subset of the ground vias to form ground pins. The remaining ground vias without contact elements form buried ground vias. The first and second sets of contact elements are arranged on the first surface of the core to surround each signal pin by at least one adjacent ground pin and one or more adjacent buried ground vias.

Abstract: A method for controlling a heating, ventilation, or air conditioning (HVAC) system in a building. The method includes receiving environmental data of the HVAC system via a cloud network and generating an application based on the received environmental data of the HVAC system. The method further includes providing the application to a user interface via the cloud network. The application receives control instructions via the user interface and provides control signals to a plurality of HVAC equipment in the building to satisfy the control instructions.

Abstract: The present invention relates to a connector. The connector includes: a housing; a plurality of the terminals arranged thereon for electrically contacting with a board; a pair of arms extending from two ends of the housing, respectively; a first projection and a second projection formed on each of the arms; and a metal member arranged along the length direction of each of the arms, having a hold-down portion and a first recess for engaging with the first projection with a first buffer space existing therebetween. The metal member is spaced from the second projection by a second buffer space. When the hold-down portion is soldered to a board, the first projection or the second projection may remedy overwarp of the board or the housing.

Abstract: The invention relates to methods and apparatus for displaying documents created by a particular user to that user. A source of documents created electronically by the user is accessed and an automatic selection of a plurality of parts of documents is made according to selection criteria. The selected parts are displayed sequentially on a peripheral display means associated with the user.

Abstract: An X-ray protection device adapted to be incorporated into a monitor that includes a cathode ray tube actuated by a high voltage from a transformer powered by a low voltage power supply. The X-ray protection device includes a circuit which is coupled to a low voltage output of the transformer to obtain a signal from the transformer to represent the high voltage applied by the transformer to the cathode ray tube.

Abstract: A projection lamp capable of being easily assembled to a screw socket and is both extensively and pivotally adjustable. The lamp includes a lamp housing having a conductive threaded cap an two opposite inner guiding rails, and annular member having two opposite wings capable of being slidably positioned along the guiding rails, and a lamp body pivotally connected under the annular member and having a reflective shade and a bulb electrically connected to the threaded cap.
