Abstract: Disclosed is a system for independently controlling the climate within a primary zone and at least one secondary zone of a building. The system comprises a primary packaged unit comprising a primary indoor coil and a primary variable speed indoor fan blowing over the primary indoor coil to serve the primary zone of the building. The system further comprises a secondary unit comprising a secondary indoor coil circulating the refrigerant and a secondary variable speed indoor fan blowing over the secondary indoor coil to serve a secondary zone of the building. The primary unit and the at least one secondary unit shares a common variable speed compressor, outdoor coil, and an outdoor fan that are disposed within the primary unit. First and second solenoid valves in the primary unit selectively control refrigerant flow to the primary and secondary units to enable independent control of the zones.

Abstract: A connector for electrically connecting to pads formed on a semiconductor device includes a substrate and an array of contact elements of conductive material formed on the substrate. Each contact element includes a base portion attached to the top surface of the substrate and a curved spring portion extending from the base portion and having a distal end projecting above the substrate. The curved spring portion is formed to curve away from a plane of contact and has a curvature disposed to provide a controlled wiping action when engaging a respective pad of the semiconductor device.

Abstract: A Flat Flex Connector (FFC) has connector flanges embedded in its insulated electrical traces. The flanges engage electrical circuits in a camera module such as a CMOS or CCD and are clamped into electrical engagement. The opposite end of the FFC makes electrical contact with another electrical device such as a semiconductor circuit. The assembly allows electrical connection of two or more devices in a confined space in which the electrical device are not easily aligned for electrical contact.

Abstract: A system for batch forming a sheet of spring elements in three dimensions is described. A spring element sheet containing spring elements defined in two dimensions is arranged between two mating die press plates. A force is applied to the mating die press plates to form the two-dimensional spring contact elements into three dimensions. Alternatively, configurable die press plates are used to selectively form a two-dimensional spring element sheet into three-dimensional spring contacts.

Abstract: An elastic contact array circuitized substrate includes a circuitized substrate provided with circuit traces, and an array of three dimensional contact elements joined to the circuitized substrate and electrically coupled to the circuit traces. In one configuration, the array of three dimensional contacts are formed in a spring sheet material having anisotropic grains whose long direction is selected with respect to the longitudinal direction of elastic contact arms, in accordance with desired properties. In another configuration of the invention, the circuit traces are formed integrally within the spring sheet material.

Abstract: A compliant, scalable, thermal-electrical-mechanical, flexible electrical connector. In one configuration, the flexible electrical connector comprises a flexible substrate, a first and second conductive layer, and a plating contiguously applied over the conductive layers and holes through the substrate. The first and second conductive layers are adhered to opposite sides of the flexible substrate and have a plurality of raised contact elements in registration with at least a subset of the holes. At least some contact elements on the first and second conductive layers that oppose each other are in electrical communication with one another by way of the plating.

Abstract: A scalable, low cost, reliable, compliant, low profile, low insertion force, high-density, separable and reconnectable connector for high speed, high performance electronic circuitry and semiconductors. The electrical connector can be used to make, for example, electrical connections from components such as a Printed Circuit Board (PCB) to another PCB, MPU, NPU, or other semiconductor device. A normalized working range for an array of elastic contacts of the interposer can be about 0.2 to 1.0. A reversible normalized working range is maintained through multiple connections and reconnections using a highly elastic material for the contact arms. In one aspect, a first electrical component having a first array pitch can be connected to a second electrical component having a second array pitch.

Abstract: There is disclosed lighting apparatus suitable for being positioned adjacent to an area or an object for indicating the location or orientation of the area or object. The apparatus is provided with a set of light emitters for emitting light and which are positioned side by side relative to one another. The light emitters are staggered for emitting the light outwardly from the apparatus at an increasing angle along the set relative to a plane of reference.

Abstract: An interconnect layer is fabricated using a tungsten hard mask by forming a tungsten based layer over an aluminum based layer. A photoresist layer is deposited over the tungsten based layer and patterned. The tungsten based layer is patterned by applying a fluorine-based etchant using the photoresist layer as an etch mask. Then the aluminum based layer is patterned by applying a chlorine based etchant using the tungsten based layer as an etch mask.

Abstract: A multi-media presentation system is disclosed for coordinating access to multi-media presentation data and related information. The multi-media presentation data typically includes text, image data and layout data. The related information is stored in an item header file, as well as in a number of records. The system includes a network of computers including computers dedicated to performing certain tasks related to obtaining multi-media presentation data and such related information. To coordinate the multi-media presentation process, the ability to modify content contained in an item file is limited while certain of the records that include useful information related to the same item file are separately available for other network staff members. The system also generates watch records to notify staff members of the current status of, availability of, or to provide other information related to, a multi-media object of interest.
