Abstract: A method and apparatus for controlling working fluid surge in a centrifugal compressor (10) include preventing surge by using a variable-speed prime-mover (14) to achieve a minimum desired surge margin. Surge prevention is also accomplished by continuously modulating a blowoff valve (52) to maintain an actual compressor pressure ratio at a predetermined target maximum value. Surge detection is accomplished by monitoring the time rate of change of the final stage discharge pressure.

Abstract: In a process for coating a substrate with phosphor particles, for example when coating phosphor particles on a fluorescent lamp glass, a polymer is deposited on the phosphor particles and the phosphor particles are entrained in a carrier gas with the polymer in a non-adhering state. The phosphor particles are then coated on the substrate with the polymer in an adhering state so as to retain the phosphor particles on the substrate. The coated substrate is then heated to a temperature above a decomposition temperature of the polymer so as to remove the polymer to form a coating of phosphor particles on the substrate.

Abstract: A signal processor such as an ADPCM decoder (128b) receives an input signal. As part of the CCITT Recommendation G.726 algorithm, an inverse adaptive quantizer (41) processes the input signal to provide a quantized difference signal d q (k). When enabled, a noise detector (50) samples signal d q (k) once for each of a predetermined number of received samples. The noise detector (50) adds the absolute value of signal d q (k) to a total energy estimate. At the end of the predetermined number of samples, the noise detector (50) compares the total energy estimate to a product of a noise threshold and the predetermined number. If the total energy estimate exceeds this product, then a noise indication is provided. In another embodiment (228b) a noise detector (250) compares an existing energy estimate signal d ml (k) computed by an adaptation speed control block (48) as part of the G.726 algorithm to an energy threshold to save processing time.

Abstract: A modular step exercise unit includes a plurality of individual steps. Each step is in the form of a base having a horizontal platform which comprises the upper surface of the base with depending sides forming an apron which terminates in a plane parallel to the platform so that the apron can be placed directly on a support surface, such as a floor. The steps may be made of differing size so that during storage or even in certain use conditions, steps which are not being used can be stored within the periphery of the apron of the largest step. A multi-level step can be formed by mounting a smaller step on a larger step. The individual steps could be used abutting each other or spaced from each other to provide a multi-level arrangement which includes individual steps and the floor. If desired the steps could be of the same size as each other which would eliminate the advantage of storing the steps within each other during non-use, but would have the advantage of providing a more symmetrical exercise unit by equal sized steps.

Abstract: The present invention provides mice and mouse cell lines having a homozygous or heterozygous deficiency in a gene encoding a neurotrophin receptor. In a preferred embodiment of this invention, mice and cell lines carry a trkB locus specifically targeted within its tyrosine protein kinase sequences. Mice homozygous for this mutation express gp95 trkB  receptor of unknown function but not the high affinity functional gp145 trkB  tyrosine protein kinase receptors. This mutation results in multiple CNS and PNS neuronal deficiencies and in a postembryonic lethal phenotype. Such genetically modified mice are useful in model systems for studying human diseases involving neuronal degeneration and neuronal cell loss, as well as in screening for genes, proteins, or other compounds that may prevent or impede neuronal cell death or stimulate neuronal regeneration.

Abstract: An electronic digital control system monitors and controls the operation of an engine fueling system. Signals activating injection for a plurality of cylinders are transmitted through a single line to a driving circuit for a single injector solenoid valve, while signals controlling accumulator fuel pumps are transmitted to pumping control solenoids. Injection signals are controlled to vary fuel delivery rate during an injection event. A back EMF sensing circuit measures valve opening delay and the control system compensates for valve delay. Variable cylinder-specific delays in the injection solenoid output signal pulses are programmed to compensate for a varying fuel line length to each injector nozzle. At startup, the control system pulses the pumping control solenoids to begin pressurizing the accumulator before engine angular position sensors provide an accurate indication of engine angular position to allow precise timed control of the pump. Pressure variations in the high pressure accumulator are monitored by the control system in conjunction with injection events, and pump equipment failures or weaknesses are detected based on the pressure variations. In alternative embodiments of the invention, a pre-biasing current using battery voltage is provided to the injection control valve prior to the desired time of an injection event, and the current is increased at the desired time of opening. An input allows signaling the control system when a load is to be applied to cause an immediate change in fueling levels, to prepare for load increases in electrical generation and other non-motive-power applications.

Abstract: A needleless injection site allowing infusion and withdrawal of fluid therethrough is disclosed. When a compatible blunt male fluid connector fitting is inserted, fluid flow is accommodated; but upon withdrawal of the connector, the injection site is sealed against fluid flow. The injection site includes an elastomeric plunger having first and second ends and having an annular seal portion at a selected distance from the first end, movably contained within a fluid passageway through a housing having first and second ends, and biased towards a first position in sealing contact with the housing at the first end. The housing also has at least one fluid bypass opening into the passageway intermediate the ends a selected distance from the first end. Insertion of a compatible male fitting in the first end of the injection site moves the plunger to a second position where the annular seal portion of the plunger is located adjacent the fluid bypass opening. This allows fluid flow through the passageway, bypassing the seal portion through the fluid bypass.

Abstract: A low voltage submicron CMOS circuit (10) for providing an output bandgap voltage (V BG ) that is substantially independent of temperature and power supply variations has been provided. The CMOS circuit utilizes parasitic transistors (28-30) to create a delta voltage that has positive temperature coefficient across a differential pair of NMOS transistors (14, 16). This delta voltage is then converted into differential currents which are amplified and mirrored and summed together to provide an output current (I O ) that has a positive temperature coefficient. This output current is then passed through a series network including a resistor element (52) and a parasitic PNP junction transistor (31) to provide a bandgap voltage of 1.2 volts wherein the voltage across the resistor element has a positive temperature coefficient and the voltage across the parasitic PNP junction transistor has an inherent negative temperature coefficient.

Abstract: A binary number is generated representative of net motion during a field interval of an interlaced video signal from which a field to field difference signal is derived having a sign bit and a group of magnitude bits. The magnitude bits are compared with a first threshold to provide a first threshold indicating signal which, with the sign bit, are applied via respective bus lines to each correlator of a group of five correlators. The correlators are addressed using variable moduo addressing to detect patterns representative of 2-2 pull down and 3-2 pull down film originated frames. Logic is provided for detecting when one and only one of the five correlators indicates film detection to verify film mode operation. Error reduction is further enhanced by comparing the field difference signal with a second threshold, higher than the first, to provide a second thresold indicating signal to each correlator via a second bus. Flags are produced for identifying film mode operation and for identifying also which of two adjacent fields are suitable for use in subsequent video processing such as de-interlacing or flicker reduction.
