Abstract: A parallel declarative data processing system comprises a number of data processing elements. A source program is initially produced in a high-level language such as HOPE, and then compiled to produce a set of packets, which are distributed to the processing elements for execution. 
     Expressions in the source program carry locality annotations, which specify the preferred locations for executing the expressions. These annotations are used to route the packets to particular processing elements. Thus, for example, it can be arranged that a specified set of expressions will all be executed on the same processing element.

Abstract: The call hand-over technique of this invention is characterized by the use of channel information from both the target base station (24b) and subscriber terminal (22) in determining which radio traffic channel will be used to hand over a call in progress from a serving base station (24a) to a target base station (24b). Calls are handed over to the radio channel which, of a set of channels under consideration by the subscriber terminal (22), contains the least amount of interference as measured by the subscriber terminal. The set of channels under consideration by the subscriber terminal is a subset of the entire set of channels allocated to the service. This subset is comprised of those channels having little interference, as measured by the target base station. The hand-over technique thereby assures that calls proceed on channels containing little interference from the viewpoints of both the target base station (24b) and the subscriber terminal (22).

Abstract: An information processing network (16) includes multiple processing devices (18,20,22,24) a main storage memory, and an interface (26) coupling the processing devices to the main storage memory (28). All processing devices contend for control of the interface on an equal basis, subject to a dynamically shifting sequence of priority rankings, invoked to resolve contentions for the interface or for one of a plurality of hardware class locks. The class locks are uniquely associated with different capabilities or classes of data operations, which reduces the number of contentions and allows multiple operations to proceed simultaneously. Arbitration logic (56,114,116,118) encompassing all of the processing devices is duplicated in each of the processing devices, and kept coherent through an interconnection of multiple data buses (58) One bus is associated with each processing device, receives the output of the associated processing device and provides the output to each of the other processing devices. A lock sequencer includes a store-tracking feature that minimizes the time that any processor, after losing a contention for a lock, is in a hold condition.

Abstract: A method is disclosed for the cyclic regeneration of a water softening system comprising an exchange medium in a tank which is in fluid communication with a brine storage tank. This method comprises the steps of filing the brine storage tank with refill No. 2 of softened water in a quantity sufficient to create sufficient brine for said exchange medium, said brine storage tank already containing refill No. 1 of softened water from a later step of the method. The exchange medium is subjected to backwashing No. 1 with water flowing counter the direction of water flowing therethrough during water softening operations. Next, brine from the brine storage tank is passed through the exchange medium. Water then is passed through the brine exchange tank. The exchange medium thereafter is subjected to backwashing No. 2 with water flowing counter to the direction of water flowing therethrough during the water softening operation. Finally, the brine tank is refilled with refill No. 1 of softened water to create brine in a quantity insufficient for completely brining the exchange medium.

Abstract: A serial clock generating circuit is configured to frequency-divide an input clock having a frequency which is a number times a serial data transfer rate, so as to generate a serial clock in phase with a received serial data. The serial clock generating circuit comprises an edge detection circuit for detecting a level change of a received serial data so as to generate a level change signal. Three registers stores different set values, and a latch latches one of the different set values. A decrementer decrements the value of the latch in response to each input clock, and a memory circuit holds an arbitrary value for defining a phase deviation discrimination area. A comparison circuit compares the value stored in the memory circuit with the value of the latch at each one input clock, and generates a coincidence signal when a coincidence is obtained. An area detection circuit discriminates a level change position on the basis of the level change signal and the coincidence signal and selects one of the registers to be set to the latch. A flipflop is coupled to the decrementer for generating a serial clock on the basis of the result of the counting of the decrementer.

Abstract: A mass biosensor method provides enhanced quantification of analyte concentrations in a sample. In a direct approach (200), an analyte is derivatized to form a analyte chelate and then specifically bound to a sensor (108). In an indirect approach (300), a complement of the analyte is derivatized to form a complement chelate which is then bound to a sensor. In a direct/indirect hybrid approach (400), an analog of the analyte is derivatized to form an analog chelate that is bound to a sensor in competition with the sample analyte. In all three approaches, mass measurements taken (at 204) as the ligand chelate attaches to the sensor permit the concentration of the analyte in the sample to be calculated. Once measurement is completed, a dissociation treatment is applied (at 205) to dissociate the derivatized species from the sensor so that the sensor can be reused. The effects of the dissociation treatment can be monitored (206-208) using phosphorescence detection. The results obtained during monitoring can be compared with a predetermined threshold to ensure complete dissociation while avoiding alteration of the sensor surface. This procedure permits precision renewal of a sensor to maximize the number of times a sensor can be used. Moreover, this method allows quantification to be performed using the same sensor and coating in place during calibration, minimizing systematic errors and enhancing quantification accuracy.

Abstract: An asynchronous handshake signal (111,151) is encoded in order to facilitate the transfer of the asynchronous handshake signal (111,151) from a first network segment (10) to a second network segment (30). On the first network segment (10), control signals and data signals are encoded as control symbols (122,125,128,130,132,135,138,140) and data symbols (123,127,129,133,134,137,139), respectively. The control symbols (122,125,128,130,132,135,138,140) and the data symbols (123,127,129,133,134,137,139) are transferred from the first network segment (10) to the second network segment (30) across an intercon - nection medium (41,42). In order to send a hand - shake signal (111,151) from the first network segment (10) to the second network segment (30), the handshake signal (111,151) on the first network segment (10) is sampled. When the handshake sig - nal (111,151) on the first network segment (10) is at a first signal level, a control symbol (122,125,128) of encoded control signals is sent across the intercon - nection medium (41,42). When the handshake signal (111,151) on the first network segment (10) is at a second signal level, a data symbol (123,127,129) of encoded data signals is sent across the intercon - nection medium (41,42).
