  • Patent number: 8010926
    Abstract: Power, routability and electromigration have become crucial issues in modern microprocessor designs. In high performance designs, clocks are the highest consumer of power. Arranging clocking components with regularity so as to minimize the capacitance on the clock nets can help reduce clock power, however, it may hurt performance due to some loss of flexibility in physically placing those components. The present invention provides techniques to optimally place clock components in a regular fashion so as to minimize clock power within a performance constraint. A rectangular grid is created and clock distribution structures are assigned to the grid intersection points. Latches are then located around the clock distribution structures to minimize an overall distance for connections between the latches and respective clock distribution structures. The horizontal and vertical pitches of the grid may be independently adjusted to achieve a more uniform spread of the clock distribution structures.

  • Patent number: 7911263
    Abstract: A dormant mode target semiconductor device within a leakage current target unit is identified for mitigating leakage current to prevent it from reaching catastrophic runaway. A leakage current shift monitor unit is electrically connected to the output node of the leakage current target unit and collects leakage current from the selected target semiconductor device for two consecutive predefined temporal periods and measures the difference between the collected leakage currents. A comparator receives and compares the outputs of the current shift monitor unit and a reference voltage generator. The comparator propagates an alert signal to the leakage current target unit when the leakage voltage output from the leakage current shift monitor unit exceeds the reference voltage, a condition that indicates that the leakage current is about to approach catastrophic runaway levels.

  • Patent number: 7082725
    Abstract: In recent decades within the building industry, there has been a trend toward mass production of building components. The trend has included every part of structures except for the concrete slab the building is built on. The “Threshold Tray and Clip System” uses mass-produced products to be applied to construction of slabs and foundations, allowing sill steps to be built in rough openings with pre-fabricated form parts. The forms remain in the concrete and are permanent. This means that consistent results can be expected. Other mass-produced products, such as door systems, will fit into rough openings more accurately. Over-all quality of the structure will be increased.

  • Patent number: 7004094
    Abstract: A system for reducing skin friction drag includes a user-controlled drag reducing substance and components for introducing the substance at or near the surface of the object for which skin friction drag is desired. In a fluid injection system embodiment, a pressurized injectant source supplies an injectant, an injector device injects the injectant near the surface of the object for which drag reduction is desired, a hose or conduit directs flow of the pressurized fluid from the source to the injector device and a control device enables a user to control the flow.

  • Patent number: 6859967
    Abstract: An overlay mattress has a plurality of internal elevating means, such as inflatable bladders, for raising selected portions of the mattress to achieve a wide range of patient positions. A fluid such as air may be supplied from a conventional surgical room air supply, a compressed canister, or a compressor to inflate the bladders. A fluid distribution system controls the flow of fluid to desired bladders. The overlay mattress may be used in conjunction with conventional surgical tables and mattresses. A thermal control means is also included in the overlay mattress to regulate a patient's body temperature. A pressure shifting means is also included to reduce the risk of bedsore formation.

  • Patent number: 6857480
    Abstract: A head edger apparatus for producing a centered, uniform, repeatable cut around sprinkler heads (or similar objects), without marring or damaging the sprinkler heads includes a body, a plurality of cutting members releasably and adjustably attached to the body, a non-slip boot rotatably mounted to the center of the body. The body may be securely engaged to a rotatable shaft of a motorized trimmer. Rotation of a trimmer shaft causes the body to rotate. Cutting portions of the cutting members travel in a circular orbit having a determined radius, cutting a circular path as they travel around the sprinkler head. The boot is positioned on the top center of the sprinkler head, protecting the sprinkler head and providing a stable support around which the cutting members travel.

  • Patent number: 6289033
    Abstract: An environmentally controlled heating system for heating metal alloy billets wherein a trolley system carries the billets through the chambers of the induction heating system in crucibles that are pushed or pulled by actuators. The billets enter the system through a load-chamber and travel through a main chamber to a heating area where the loaded crucibles pass through a series of induction heating coils. The heated billets leave the heating area through a dump-chamber where they are delivered to a forming system. The empty crucibles reenter the main chamber and travel back to the loading area to receive another billet. The heating system is controlled through a computing device for monitoring and controlling the system, preferably a programmable logic controller. A vacuum system evacuates air from the chambers, and an inert gas system back-fills the chambers with an inert gas. A gettering system continually cleans the inert gas.

  • Patent number: 6209598
    Abstract: The sign covering of the present invention is an all weather covering for concealing the insignia side of a sign, and more particularly a roadway sign. The covering is made of a weather resistant fabric, such as polypropylene, and is light enough for a single person to install. The sign covering does not damage the sign nor is it susceptible to the elements. Typically, straps affixed to a sheet covering the insignia side of the sign hold the cover in place. The straps are tied at the back of the sign using a cord fitted through the eyelets of grommets positioned at the free end of each strap and into the corresponding grommets that are positioned at the opposite edge of the sheet. Once securely attached, the sign cover effectively hides the insignia side of the sign from view.

  • Patent number: 6092149
    Abstract: A magnetic disk drive with a caching system includes an intelligent interface to communicate with a host, a magnetic disk and a cache memory to buffer data transferred to and from the host. The caching system maximizes drive performance based on past access history. The caching system alters execution of commands by coalescing commands or executing internal commands in parallel. The caching system anticipates data requests by using a prefetch to store data that may be requested. The caching system divides the cache memory into segments to store multiple streams of data. The number of segments may be continuously adapted according to the types of access to maximize performance by maintaining a segment for each sequential stream of data. The caching system uses a dynamic priority list to determine segments to maintain and discard. Each segment is monitored to determine access types such as sequential, random, and repeating.
