The apparatus is independent of the applications that manipulates the anchors linked by the links being managed. Anchors linked may reside on the same or different computers on a network. Links managed comprise navigation links and include links. Links managed may be further extended with application defined links. Application defined links may or may not require support by additional application provided link maker programs. Application defined links may inherit linking operations managed from the navigation link, include link and other existing application defined links with or without override.

Abstract: In a communication system including a plurality of networked stations that communicate using a slow frequency hopping system, a method for encoding a packet of data in a transmitting station and decoding the data in a receiving station. In the transmitting station, the packet is divided into data segments. Error correction segments are added to correct the data segments. The segments are fragmented into a series of fragments, and a data error control field is calculated for each fragment and appended thereto. The data units including the segments are transmitted, and in a receiving station all or a portion of the bursts are received. The DEC field for each received fragment is calculated and compared with the received DEC field to determine whether each fragment is good or bad. If there are a sufficient number of fragments in each column, then the data can be reconstructed.

Abstract: A method and apparatus for providing a correctly signed result of a linear interpolation (LIRP) function in a compute controlled display system. A correctly signed LIRP evaluation may be performed by simply adding a bias to each of the operands of the LIRP function and subtracting the bias to the result. Adding the bias is achieved by inverting the high (sign) bit of each of the operands. Subtracting the bias is achieved by inverting the high (sign) bit of the result.

The reagents are input and withdrawn from opposite edges of the sample membrane. The present invention has a minimal dead volume as a result of the spacer arrangement.

Abstract: An integrated circuit which includes a pair of serially arranged P channel transistor devices connected with their source and drain terminals in series. The devices are constructed as N well devices in a P substrate. Using a pair of N well devices allows higher voltages to be divided and applied across the two devices without reaching the breakdown limits of either the oxide or the junctions between different portions of the devices used in the process. These devices have been found capable of transferring ten or more volts to circuitry for programming or erasing flash EEPROM cells even the they are a part of integrated circuitry designed for only 3.3 volt usage.

Abstract: An adaptive active filtering method and apparatus that detects changes in noise conditions and reduces the signal propagation speed as noise conditions worsen. This active filter has a level shifting inverter, which inverts the input signal and converts the logic levels of the input signal into chip logic levels. This inverted input signal is presented at the input of a driver inverter, which once again inverts the signal. This second inversion filters out input noise, because a voltage controlled device (which is attached to the driver inverter) reduces the switching speed of this inverter as the noise condition worsen; this reduction in switching speed reduces the propagation speed and thus filters out noise.

Abstract: An asynchronous transfer mode (ATM) network or the like providing for formation of resource hunt groups. The hunt groups are formed by devices of the same class (e.g., servers such as multicast servers) by devices registering with a central management supervisor (also referred to herein as a hunt group manager) through communication of hunt group registration requests over the virtual service path of the switches to which devices are attached. The central management supervisor communicates with an acknowledgement message back to the requesting device, again over the virtual service path. After formation of a hunt group, devices requiring the services of a device registered in the hunt group can communicate a request for establishment of a communication path to the central management supervisor. The central management supervisor then establishes a communication path with an available one of the devices in the hunt group.

Abstract: A circuit and method are provided for a pad efficient and speed efficient test of column leakage currents in silicon memory devices. Memory circuits are blocked into memory bit planes associated with individual I/O pins. Adequate testing requires that each column in each bit plane be tested for charge leakage characteristics. Rather than switching between I/O pins to test memory blocks associated with given pins, the switching circuitry is implemented on the silicon and is selectively coupled to the outputs of the bit planes on the chip. A single high voltage analog output pin is provided for test observations. This eliminates the need to ramp the testing system's voltages up and down and avoids the problems of hot switching between I/O pins.

Abstract: A method and apparatus employed in an X-ray apparatus for compensating for attenuation caused by a subject to perform an improved X-ray exposure. A table is created comprising entries accessible via power and attenuation values. Each of the entries includes a first value T representing a time for radiation in the system to reach a base ion count, and a second value C representing an offset ion count from the base ion count. A first set of entries in the table are referenced using a first power setting, and a first base ion count is determined based upon the first power setting, and a maximum radiation exposure is determined for the first power setting and a subject's mass. Then, an X-ray emitter is activated until a current ion count from a radiation sampling means has exceeded the base ion count or total radiation emitted has exceeded the maximum radiation allowed for the given mass of a subject.

Abstract: A football having an end appendage comprising at least one long, narrow strip of a flexible sheet material, e.g., cloth of flexible plastic, which functions as a tail when the ball is thrown or kicked and which provides directional stability for the football while in flight. When multiple strips are used which are formed of a rigidly flexible sheet such as MYLAR, the appendage also functions as a sound generator. When the football is thrown in a normal manner, the tail extends backwards, providing a slight drag to cause the back tip of the ball to align itself with the front rip, thereby resulting in the straight and accurate flight of the ball. One end of the appendage is preferably detachably/attached to an end of the football by interlocking hook and loop material, commonly known as VELCRO.

The bridge circuit includes a first set of switches and a second set of switches. When the first set of switches are activated, a positive current flows through a speaker load.

The modulation signal may be, for example, a plurality of pulse code modulated samples representing sound. The dynamic range reduction circuit modifies a selected signal to reduce the dynamic range of the sound reproduced based on the modulation signal. The selected signal is either the modulation signal or a reference signal.
