Abstract: A computer system having a core logic chipset that functions as a bridge between an Accelerated Graphics Port ("AGP") bus device such as a graphics controller, and a host processor and computer system memory wherein a Graphics Address Remapping Table ("GART table") is used by the core logic chipset to remap virtual memory addresses used by the AGP graphics controller into physical memory addresses that reside in the computer system memory. The GART table enables the AGP graphics controller to work in contiguous virtual memory address space, but actually use non-contiguous blocks or pages of physical system memory to store textures, command lists and the like. Contiguous virtual memory address space must be allocated for the AGP device within the addressable memory space of the computer system, typically 4 gigabytes using 32 bit addressing.

Abstract: A self-aligning, anti-cross threading fastener having first and/or second members with lead threads having a curved surface feature from the minor diameter to the major diameter which allows the surface of the lead threads to cam over the mating threads of the other member and thereby aligning collinearly the longitudinal axis of the two members. The initial presentation angle of the two threaded members may be restricted and therefore enhanced by providing a protruding diameter feature.

Abstract: Magnetic particles are used as the solid phase to carry out immunoassay. In a reaction vessel, the magnetic particles are mixed with a sample containing TSH as an analyte and a labeled antibody. A chemiluminescent label material is bound onto the magnetic particles with an immunoreaction. A fluid including the above mixture is introduced to a chamber inside a flow through cell, the chamber being sized to have a width greater than a depth. The magnetic particles in the fluid are trapped by a magnet so as to be spread in the planar form over a predetermined area within the chamber, while useless materials are discharged outwardly of the chamber. The chamber is then filled with a buffer solution containing an attractant. By applying a voltage to electrodes disposed in the chamber, the label material on the magnetic particles is excited to emit an electro-chemiluminescence. The luminescence is detected by a photomultiplier.

Abstract: A system for allowing a peripheral device to be inserted directly into a port of a computer system while the computer system is powered on.

Abstract: A free-running microcontroller (i.e., one without any reset signal) is shown with special mode enable detect logic for placing the microcontroller into the test or special operations mode, without the benefit of a dedicated pin for such purposes. Rather, the instant invention implements the methodology of first applying a test voltage to indicate to the free-running microcontroller that the test mode is to be entered. Since the device has no reset signal to interrupt normal operation once it has begun, the test voltage is applied before the power supply V.sub.DD to ensure that the device enters test mode before it can enter normal operation.

Abstract: An improved reprogrammable memory device permits definition of a page within an array of memory cells which is variable in size, erasure of only that data contained within the defined variable page while uneffecting the remaining data in the array of memory cells and reprogramming the defined variable page.

Abstract: A computer system having a core logic chipset that functions as a bridge between an Accelerated Graphics Port ("AGP") bus device such as an AGP graphics controller, and a host processor and computer system memory wherein AGP transaction read requests are merged from the AGP graphics controller and retired when these requests are within a cacheline of the memory being accessed. The core logic chipset will request a memory cacheline read as it begins processing a current AGP transaction read request. Once the memory read access is initiated, the transaction read request will be popped off an AGP request queue in order to evaluate the next in order transaction request. If the next request can be partially or completely retired by the memory read access previously started, then the memory access that would have been normally required may be skipped and the data from the previous memory read access is used instead.

Abstract: A system for allowing multiple addressing modes while maximizing a number of available opcodes and addressable registers. The system has a processor architecture scheme which allows for encoding of multiple addressing modes through use of virtual register addresses. The system has an instruction set having a plurality of instructions. Each instruction has a plurality of bits wherein none of the plurality of bits in each of the plurality of instructions are dedicated bits for implementing different addressing modes. Each of the plurality of instructions are able to implement different addressing modes by addressing the virtual register addresses in the processor architecture scheme. Since no bits are required for implementing different addressing modes, the length of the opcode field and the register address field are determined by the number of opcodes and the number of addressable registers the user wishes to implement.

Abstract: A polymeric wave guide comprises a first layer of a polymer having a first refractive index, and the first layer contains retaining features or groves which will accept a second polymer. A second polymer is curable and is used to fill the retaining features has a refractive index which is greater than the polymer used to produce the first layer. The retaining features of the first polymeric layer are filled with the second polymer by pressing the second polymer into the retaining features by applying an advancing force to a flexible dispensing layer; this results in filling the retaining features and producing a thin over layer having a thickness of less than 1.5 .mu.m of the second polymer over the surface of the first layer. The method further comprises a step in which the second polymer is cured.

Abstract: A highly clean fluid treatment system having a small system volume is provided by using a Bernoulli holder to accomplish stable holding of a specimen in a simple configuration. A holder having a specimen hold face formed almost the same as a specimen or having a Bernoulli effect producing region and a region surrounding the Bernoulli region made of a specific combination of materials is used and fluid supply sources are connected to the holder for supplying one or more fluids containing a treatment agent of a specimen. Since a force for inhibiting a position shift occurs on the end face of the specimen 10, stable specimen holding is enabled. The space between the specimen and the holder where treatment is executed is narrow and fluid always flows from the treatment space to the outside. Therefore, the fluid treatment system of a small volume producing high treatment efficiency and minimizing the chances of recontamination of the specimen can be provided.

Abstract: A method for allowing flexible multiple access to a serial bus by a plurality of circuit boards. Before a circuit board can be used on a common serial bus with other circuit boards, a unique software address must be assigned to each circuit board. The unique software address is assigned by having a bus master device issue Assign Address commands which utilizes a unique serial number which is stored on each circuit board. The Assign Address command queries each of the circuit boards coupled to the serial bus and assigns a unique software address to each circuit board that fully responds. The Assign Address command is repeated for each circuit board on the serial bus until all of the circuit boards on the serial bus have been assigned a unique software address.

Abstract: A computer system comprising at least one processor and associated cache memory, and a plurality of registers to keep track of the number of cache memory lines associated with each process thread running in the computer system. Each process thread is assigned to one of the plurality of registers of each level of cache that is being monitored. The number of cache memory lines associated with each process thread in a particular level of the cache is stored as a number value in the assigned register and will increment as more cache memory lines are used for the process thread and will decrement as less cache memory lines are used. The number value in the register is defined as the "process thread temperature." Larger number values indicate warmer process thread temperature and smaller number values indicate cooler process thread temperature. Process thread temperatures are relative and indicate the cache memory line usage by the process threads running in the computer system at a particular level of cache.

Abstract: A transparent shield is attached to a template and workpiece and used to move the workpiece against an inverted router blade. The transparent shield prevents inadvertent contact of fingers or hands with the router blade, yet allows visual observation of the workpiece proximate to the router blade. A router table may support the workpiece being cut by the router blade. Handles may be attached to the transparent shield for holding thereof. Sensors in the router table may determine the position of the transparent shield in relation to the router blade and the router blade may be stopped if the transparent shield is not covering the router blade. A video camera may be positioned over the router table. The router table, router blade and transparent shield images may be tracked in relation to one another such that if the transparent shield is not covering the router blade, then the router blade may be stopped.
