Abstract: An access node has a portal which performs interfacing between a wireless network domain and content/service providers in the Internet. On the wireless side the portal is linked with an SMSC, a CBC, and a USSD server for interfacing with and management of bearer stacks. Service functionality includes modular systems including a Push server, a Pre-paid calling server, and a location server in addition to internal portal functions. The latter provide for subscriber self-provisioning, customer care provisioning, subscriber device provisioning, and service provisioning. Thus, the node caters for both particular subscriber service and mobile device requirements.

Abstract: A facile process for the preparation of 4,6-dichloropyrimidine is provided, which utilizes quaternary ammonium salts or quaternary phosphonium salts as catalysts for the reaction of, for example, 4,6-dihydroxypyrimidine or 4-chloro-6-methoxypyrimidine with phosgene.

Abstract: A microbiocidal composition including a first component comprises a guanidine compound, a second component which comprises either prochloraz, propiconazole or iodocarb, wherein the weight ratio of first component to second component is in the range of from about 32:1 to about 1:16. The microbiocidal composition provides effective and broader control of micro-organisms in various industrial systems and for household products, agricultural products and biomedical products.

Abstract: An Address Generation Unit (AGU) for a processor such as Digital Signal Processor that includes a data memory addressable to obtain X and Y operands and a program decoder. The AGU is connected to the data memory and the program decoder and includes two Arithmetic Logic Units that are used to generate the X and Y operands. Each alu a has a triplet of registers associated there with and include a linear path of a first DBLC adder. The first DBLC adder has an A input, a B input, a carry input connected to receive a first control signal, and a summation output. The linear path further includes a by pass connection for by passing the first DBLC adder. A multiplexer selects either the summation output or the by pass as a linear output. Each alu also includes a modulo path that is in parallel with the linear stage. The modulo path has a series connection of a Carry Sum Adder (csa) and a second DBLC adder with a modulo output. A second multiplexer selects either the linear output or the modulo output as a result.

Abstract: 4,6-Dichloropyrimidine is prepared by treating 4,6-dihydroxypyrimidine with a chlorinating agent of the formula R.sup.1 R.sup.2 R.sup.3 PCl.sub.2 wherein R.sup.1, R.sup.2 and R.sup.3 are independently alkyl or aryl, or one or more of the groups R.sup.1, R.sup.2 and R.sup.3 is linked to a polymer support. Conveniently, the chlorinating agent may be prepared in situ by reacting the corresponding phosphine oxide with phosgene. Thus, in a preferred process, 4,6-dichloropyrimidine is prepared by treating 4,6-dihydroxypyrimidine with phosgene in the presence of a phosphine oxide.

Abstract: This application relates to analog to digital converters, particularly AD convertors of the successive approximation type, and to the reduction of power consumption and/or the size of active devices used in these converters. In particular, an analog to digital converter is disclosed in which an array of switched capacitors is decoupled from a comparator. Preferably, this decoupling is achieved using a small capacitor.

Abstract: A wire tying tool having a set of movable talons for channeling a loop of hard wire around a rebar joint or other object(s) to be tied with a wire knot at high speed; a heavy duty wire drive with a pullback feature to retract the loop under tension to tighten the loop around the joint; a clutch-controlled retractable reel to hold the tension on the hard wire on the reel; a spinner/cutter that extrudes a knot by turning, kinking, and cutting the wire (holding the cut ends under tension) and then spinning in complete revolutions to twist the wire into a knot while drawing the spinner away from the work surface. In a preferred embodiment a single reversible motor powers each of a wire drive, a talon drive and a spinner drive; logic and control elements control a sequence of operations of the various drives.

Abstract: The invention is a tester that uses a capacitive probe to test whether components that have multiple power and/or ground pins are correctly oriented relative to the signal-pin tracks on a circuit board. The tester connects, to the signal-pin track to which the pin under test is connected, a test-signal source that supplies to that pin a relatively high-voltage test signal. The tester actively guards the pin by applying to the remaining component pins, through the tester scanning system and its internal resistance, a signal that has the same voltage as that sensed by the capacitive probe. If the component is oriented such that one of the multiple power or ground pins is connected to the signal-pin track to which the test signal is applied, the test signal appears also at the other power or ground pins, since these pins are interconnected by a low impedance path through the component.

Abstract: A protective member for a display device such as an LCD display mounted in a display system provides protection to the display device against ultraviolet light and shock. In one embodiment, the protective member is mounted between the display device and at least one source of light energy which includes both ultraviolet light energy and visible light energy. In another embodiment, the protective member is used to actually fabricate the display device. The protective member blocks generally all of the ultraviolet light energy which has a wavelength of between 200 to 390 nanometers, while transmitting at least 90 percent of the visible light energy having a wavelength greater than approximately 410 nanometers. The protective member has a thermal coefficient of expansion (TCE) of between 45.times.10.sup.-7 /.degree. C. and 60.times.10.sup.-7 /.degree. C., so as to be useable with present day manufacturing processes for such display devices.
