Abstract: Disclosed is a method for converting a SPICE format circuit description to a standard cell HDL netlist, such as Verilog, allowing simulation and verification in HDL format. SPICE elements may be converted to circuit functions and corresponding standard cells are then selected. The SPICE netlist is employed to define timing paths. Timing information from SPICE simulation is correlated with timing characteristics of the standard cells and a standard delay file is produced such that, when applied to the standard cells, timing approximates that of the SPICE simulation. The present invention may also employ SPICE to Verilog conversion wherein a SPICE netlist is converted to a Verilog standard cell netlist. Timing information from SPICE simulation is correlated with timing characteristics of the standard cells in the Verilog netlist and a standard delay file is produced such that, when applied to the standard cells, timing approximates that of SPICE simulations.

Abstract: A test vehicle for evaluating a manufacturing process for integrated circuits comprises a staircase of vias and traces arranged for maximum test coverage. The staircase may be combined with several functional cells to produce circuits that exercise many interconnections that may be designed at the minimum design parameters of manufacturing process. The accessibility of many testing methods allows an engineer to quickly find root cause failures and thus make improvements to the manufacturing process.

Abstract: A rectangular termination ring for a power distribution mesh is placed on the upper two layers of an integrated circuit and may be placed over some I/O circuitry. The strapping connecting the bonding pads to the termination ring are placed on upper levels of the integrated circuit, minimizing the via requirements and freeing space for additional circuitry. Further, the termination ring may be adapted to work in conjunction with L-shaped, as well as other power distribution meshes.

Abstract: A system for dynamic allocation of voice and data channels in a time division multiplexed telecommunication system is disclosed. Multiple time division multiplexed lines are provided between a Teleco central office and a number of remote terminals. The time division multiplexing provides multiple channels on each of the multiple DSL lines so that multiple POTS devices can be connected to a single remote terminal. In addition, the remote terminal provides a high speed data port for connection to a data device such as a computer, a router, a bridge, a switch or other similar devices. The multiple TDM channels on each DSL line are allocated so that all of the channels are available for transmission of voice signals and all of the remaining open channels are available for the transmission of data signals.

Abstract: The present invention includes maintaining the region of the proximal lens of a laparoscope at greater than ambient temperature in order to prevent fogging during use. Heating is accomplished using commercially available chemical heat packs generally used for heating boots or gloves, or by using electrically powered heating tape. The invention differs from other anti-fogging devices, which either immerse the distal lens region of the laparoscope in a warm fluid or treat this lens with anti-fogging solutions, in that above-ambient temperature is continuously maintained throughout the laparoscope, since it is known that a cool laparoscope fogs when placed in the vicinity of warm, wet patient tissue.

Abstract: A static random access element is comprised of three transistors and two resistors. Two transistors have their gates and drains cross connected to the respective drains and gates of the opposite transistor. Two resistors make the connection from a power supply to the drains of each of the two transistors. A first control line is connected at the junction of the two resistors. The source of a third transistor is connected to the gate of one of the first transistors and the drain of the third transistor is connected to a second control line and a power supply. The gate of the third transistor is connected to a third control line. The three transistor SRAM cell is more compact and requires fewer control lines than typical SRAM cells.

Abstract: Persistent reservations may be processed on an as-needed basis after a power cycle sequence. A computer storage device may have persistent reservations for various volumes that are to be deleted after a power cycle but before accepting any reservation I/O requests for those volumes. After a start up sequence, the device comes on-line prior to deleting the required registrations. Prior to the first reservation I/O request for the particular volume, the registrations are processed for that volume and the necessary registrations are deleted.

Abstract: Accurate models of the contact region of an integrated circuit resistor are created in a single function. The function incorporates many contact geometries into a single function that cannot otherwise be represented by a closed form solution. A method of creating the function uses regression over the simulation results for many combinations of input variables. The function may use the contact resistance, metal trace resistance, and resistive area resistance as inputs to calculate the resistor contact region resistance.

Abstract: An apparatus and method for the generation of ultrabright multikilovolt x-rays from saturated amplification on noble gas transition arrays from hollow atom states is described. Conditions for x-ray amplification in this spectral region combine the production of cold, high-Z matter, with the direct, selective multiphoton excitation of hollow atoms from clusters using ultraviolet radiation and a nonlinear mode of confined, self-channeled propagation in plasmas. Data obtained is consistent with the presence of saturated amplification on several transition arrays of the hollow atom Xe(L) spectrum (&lgr;˜2.9 Å). An estimate of the peak brightness achieved is ˜1029 &ggr;·s−1·mm−2·mr−2 (0.1% Bandwidth)−1, that is ˜105-fold higher than presently available synchotron technology.

Abstract: The present invention is a solar powered aeration system that incorporates a battery. The device can be used for improvement of water bodies for use in aquaculture systems, reservoirs, water storage tanks, fish tanks, artificial ponds and lakes, and the like. The device does not require connection to the electrical power grid and may be used in any location. Further, the device can be used during periods of low oxygen content, which is typically the period of day just before sunrise. Additionally, the device uses a laminar column of water to enhance circulation of the water body. Increased efficiency can be obtained by matching the diffuser to the pump size, which is important in solar powered applications.

Abstract: A system and method for dynamically generating the topology of a storage array network by linking information concerning hosts and clusters along with information about host port adapters. Namely, each host identifies itself to all controllers and provides information in a command that allows the controller to know which host and cluster, if applicable, is associated with the host port adapter through which the command was issued. In addition, the topology is automatically updated anytime there is a change on the network such as a new device was added or a host port adapter was replaced.

Abstract: An active heat sink uses a liquid coolant to transfer heat from a hot zone to a cool zone. The liquid coolant is propelled using a motor comprised of a plurality of external coils that are in magnetic communication with a plurality of magnets attached to a pump gear. The motor does not require any penetration of the liquid cavity. Further, the heat pump may have a temperature monitoring circuit to determine whether or not the pump should be activated.

Abstract: Discloses is a protective case for an electronic device that has a touch screen. The touch screen is protected with a membrane adapted to the specific contour and profile of the electronic device and allows the user to use the touch screen interface with no shortcomings. The protective case is further adapted to allow infrared and other communication signals while the device is secured inside the case. Further, electrical connections can be made through the case without affecting the protection afforded the electronic device inside.
