Abstract: There is a pressing need for computer-implemented tools that can summarize and present the enormous amounts of public literature to facilitate analysis of gene expression data. The present invention provides techniques and systems for efficiently integrating public literature regarding gene function with data from gene expression profiling experiments. Information from literature databases relating to a particular set of DNA sequences of known expression pattern is retrieved, processed, cross-referenced and viewed to provide further information about a particular DNA sequence to facilitate its identification as a candidate gene.

Abstract: A liquid sprayer is provided. This liquid sprayer includes a bottle having an opening and a sprayer housing attached to the bottle. This sprayer housing includes an electrical motor, a voltage source for powering the electrical motor, a pump driven by the motor, a switch for completing an electrical circuit, a nozzle mechanism attached to the sprayer housing for spraying a liquid. The liquid sprayer also includes a deformable “pinched tube” mechanism which prevents liquid from flowing through the nozzle when the sprayer is not being used. The sprayer housing also includes a trigger movably connected to the sprayer housing for closing the switch, translating the piston and creating a leak-tight seal by squeezing the “pinched tube”.

Abstract: Symmetrical cross coupled PLL circuits provide pseudo-synchronization between two independent clock signals, especially for use in fault tolerant applications. Independent oscillators provide input signals to each of the PLL circuits. The PLL circuits include divide circuitry that provide output signals at some sub multiple of the input clock signals. The phase relationship between the output clock signals from the cross coupled PLL circuits is monitored by phase detector circuits. If the phase of one output clock signal is determined to be advanced relative to the other output clock signal, the phase of that output clock signal is retarded by temporarily increasing the divide ratio of the PLL circuit producing the phase advanced signal.

Abstract: A dropper tip which is adapted to be connected to a container for dispensing fluid, such as medications and like, from the container includes a body having first and second opposite ends and an inner wall defining a conduit therethrough. The inner wall smoothly diverges and gradually increases in inner diameter from the first end to the second end such that air bubbles are prevented from being permanently trapped along the inner wall. The inner wall is highly polished and may be made of olefinic material, silicone rubber material, or fluorocarbon, including, but not limited to, polytetrafluoroethylene (PTFE), carbon tetrafluoroethylene (CTFE), fluoroethylene propylene (FEP) or the like, to resist fluid wetting, facilitate fluid detachment therefrom and to reduce fluid film thickness therealong. The surface of the inner wall is smoothed to minimize surface roughness.

Abstract: An application accelerator unit (AAU) that is integrated as part of a data processor, such as an I/O processor (IOP) integrated circuit. In one embodiment, the AAU includes logic for improving the performance of storage applications such as Redundant Array of Inexpensive Disks (RAID). The AAU performs boolean operations such as exclusive-or (XOR) on multiple blocks of data to form the image parity block which is then written to the redundant disk array. Additionally, the AAU may feature adder logic configured to perform an addition such as a network header checksum calculation on each data packet. The AAU includes a memory-mapped programming interface that allows software executed by a core processor in the IOP to utilize the AAU for accelerating storage and networking applications as well as for local memory DMA-type transfers, using the chain descriptor construct.

Abstract: An apparatus and method of reducing power consumption in an integrated device having a first module with a mandatory operating frequency and a second module with a flexible frequency requirement. The integrated device is powered by a serial bus. The first module is segregated from the second module in the time domain by a frequency independent interface. The second module is then operated at a lower frequency when power conservation is needed. The operating frequency of the second module can be dynamically changed to improve performance of the second module when a power budget for the device permits.

The upper section also communicates with the lower section through its open bottom which is co-extensive with the open top of the lower section. A plurality of screens are provided in the lower section to form a series of chambers therein. The screens are positioned so that their top edges are below the plane of the bottom wall of a conventional, U-shaped gutter.

Abstract: A cache memory controller and method for dumping the contents of a cache directory and a cache data random access memory (RAM) are described. In order to dump the contents of the cache directory, access to the cache data RAM is disabled by disabling the cache controller. Then, address tags within the cache directory are read sequentially from a reserved register. In order to dump the contents of the cache data RAM, new addresses are allocated to data in the cache data RAM. This is done, for example, by blocking writes to the cache data RAM while enabling read access from the cache data RAM and both read and write access to the cache directory. A reserved block of cacheable memory within, for example, the main system memory, is accessed. When the reserved block of cacheable memory is accessed, address tags for addresses of the reserved block of cacheable memory are written into the cache directory; however, data from the reserved block of cacheable memory is not written into the cache data RAM.

Abstract: A PCI bus writes non-contiguous data in a maximum of two PCI bus write cycles. A Bridge is provided which can combine data within its write buffer such that non-contiguous data results. Some I/O devices on the PCI bus cannot handle non-contiguous data, so the Bridge detects non-contiguous data, and generates appropriate write cycles to the PCI bus to transfer this data in a contiguous fashion. The method described takes advantage of the multiple data phase capability of the PCI bus to transfer data at more than one address during one PCI bus write cycle, and optimizes these transfers to assure that all non-contiguous transfers can occur in only two PCI bus write cycles.

Abstract: There is disclosed a pail bailer having a continuous wall, an open top and a bottom that has a flood port formed therein and which is fitted with a flood screen and an internal flexible flapper valve overlying the flood port. The flapper valve is provided with a spacer bushing that permit it to flex away from the flood port when the pail bailer is lowered into water or other liquid to permit the water or other liquid to enter and fill the pail bailer. A handle is provided across the open top of the pail bailer and its ends are secured in diametrically opposed brackets enabling the handle to be rotated through an arc greater than 180.degree. or be locked within the brackets in vertical, coaxial alignment with the longitudinal axis of the pail bailer.

Abstract: An output pad for an integrated circuit includes circuitry to align the output with an on-chip clock signal, and to compensate the output such that it remains coincident with the on-chip clock signal even when changes occur in power supply voltage, manufacturing process and temperature. This output pad has a closed-loop feedback circuit which controls the delay of the output signal through a variable delay element. The loop adjust the delay until the clock edge of the on-chip clock signal is coincident with the output signal within a defined tolerance. The output pad self-compensates with every clock cycle, which is many times faster than any induced variation.
