摘要： The invention provides a heat sink assembly having a positionable heat sink permitting the heat sink to be mounted to a substrate in more than one configuration. Various features are described for permitting multiple degrees of freedom in the arrangement of the heat sink assembly. Such features permit the heat sink assembly to be adapted to different environments. The heat sink assembly also has features such as a vane for directing air flow relative to the heat sink. Features for varying and maintaining pressure between the heat sink and a component to be cooled are also included.

摘要： A printed antenna structure for transmission of radio frequency energy in the gigahertz range that provides good dispersion characteristics and a relatively wide bandwidth using a thin substrate material. The antenna includes a thin printed circuit board having top and bottom surfaces. The bottom surface features an electrically conductive ground plane layer. The top surface features a microstrip feed line structure which is connected to a radiating element. The microstrip feedline extends over the ground plane but the radiating element does not. The radiating element has a main V-shaped segment for coupling radio energy over a wide spatial region, and a tuning stub is sequentially connected to the V-shaped segment. Overall, the printed antenna has an overall shape which resembles a hook in oder to minimize the space occupied on the printed circuit board.

摘要： The printed circuit board (PCB) header attachment station mounts a header (PCB) onto a PCB having pre-existing solder joints, such as underneath a direct mount IC chip. The apparatus applies a soldering paste to PCB lands configured to receive the pins of the header; nests the header component in stacked alignment with the PCB in order to bring the header pins into contact with the respective PCB lands; heats the PCB to a temperature approaching the reflow temperature of the solder in the pre-existing PCB solder joints; and actuates a compliant heating block or bar to heat the header pins to an extent sufficient for the pins to conduct enough heat to locally reflow the solder on the corresponding PCB lands without reflowing the solder in the pre-existing solder joints. The local reflow of the solder precludes solder reflow in the surrounding pre-existing joints which may coalesce under the direct mount IC chip and render the PCB defective.

摘要： There is provided a detector for detecting conductive contaminants entrained in an airflow. The detector comprises first and second electrically conductive meshes mounted in a spaced apart relationship to provide an operational gap. Each of the meshes is sized to provide a relatively large surface for substantially intersecting the airflow and is sufficiently porous so as not to substantially attenuate the airflow. The meshes form part of an energizable electric circuit wherein the operational gap constitutes a discontinuity of the circuit. The detector includes a capacitor connected in parallel to the portion of the circuit containing the operational gap for releasing a charge stored in the capacitor through the circuit discontinuity when one of the conductive contaminants simultaneously contacts the first and second meshes. The detector further provides for indication of a discharge of the capacitor and thereby the presence of one of the airborne conductive contaminants entrained in the airflow.

摘要： A thermo-electro sub-assembly comprises a gas supply, a first duct, a first heatsink adjacent a first device, a second duct, and a second heat sink adjacent a second device. The gas supply may be realized as a fan, a blower, or a compressed gas source. The first duct provides a passageway for delivering pressurized gas from the gas supply to the first heat sink. The duct may include a plurality of vanes for reducing the turbulence and air boundary separation within the duct. The first heatsink is in thermal communication with a first heat-producing device such as a microprocessor. In a preferred embodiment the heatsink comprises an axial shaped folded fin heatsink. The second duct is used to provide a pathway for the air leaving the first heatsink and delivers the air to the second heatsink. The second duct may also include a plurality of vanes for reducing turbulence and boundary flow separation within the second duct.

摘要： A central processing unit having at least one memory for storing instructions and data includes a program counter for storing program counter values. An execution unit retrieves and processes instructions located in the memory at addresses corresponding to the contents of the program counter. Multiple stacks independent of the memory are provided for storing program counter values. A multiplexer connects the program counter to each stack. A stack select register connected to a control input of the multiplexer enables the transfer of program counter values between the program counter and one of the stacks indicated by the contents of the stack select register. The central processing unit provides an efficient multi-tasking capability since the program counter state of each task can be stored in one of the multiple stacks.
