Abstract: A method of measuring frequency interference between adjacent cell sites in a wireless telecommunications system. The method includes selecting a frequency in a cell site to be used as a beacon frequency. The method also includes activating the beacon frequency in the cell site and recording, at a telecommunications switch, a signal strength of the beacon frequency as measured by a first wireless device operating in the cell site and a signal strength of the beacon frequency as measured by a second wireless device operating in another cell site. The method further includes determining the frequency interference between the cell site and the other cell site based on the signal strengths.

Abstract: A memory array comprising a plurality of storage elements and a logic circuit. The memory array may be configured to (i) receive a plurality of input data streams, (ii) store each of the plurality of input data streams in one or more of the storage elements in response to a plurality of control signals and (iii) present a plurality of output data streams in response to the plurality of input data streams. The logic circuit may present the plurality of control signals in response to the fullness of each of the plurality of storage elements.

Abstract: A Static Random Access Memory (SRAM) comprises an input/output pin and driver means connected to the input/output pin. The driver means are configured to drive the input/output pin to a voltage potential using a first current, and are further configured to hold the input/output pin at approximately the voltage potential using a second current. In one embodiment, the driver means may comprise a driver unit for driving the input/output pin to the voltage potential, a bus hold circuit for holding the input/output pin at the voltage potential and a control unit connected to the driver unit and the bus hold circuit. The control unit may activate and deactivate the driver unit and the bus hold circuit.

Abstract: A H.sub.2 /F.sub.2 power generating system is disclosed. The system is particularly useful in producing power in military and space vehicle applications because of its high energy density and long shelf life.

Abstract: A cantilever spring (16) and a method for temporarily coupling a semiconductor package (36) to a transmission line (14) by means of the cantilever spring (16). The cantilever (16) has first and second pressure points (22, 32) that contact the transmission line (14). A force is applied to a third pressure point (32) which moves the first and second pressure points in opposite directions along the transmission line (14). In addition, the force on the third pressure point moves an end (21) of the cantilever spring (16) in a direction away from the transmission line (14). A lead (37) from the semiconductor package (36) contacts a portion of the end (21). Electrical signals are transmitted between the semiconductor package (36) and a tester via the cantilever spring (16) and the transmission line (14), wherein the electrical signals are for testing a semiconductor device (30).

Abstract: Processes are described for preparing pharmaceutical 9-carbamoyl-9-aminoalkylfluorenes and intermediates in their preparation.

Abstract: There is described a process for preparing an enamine of formula (IX): ##STR1## where R.sup.2 is a carboxylic acid protecting group and R.sup.3 is the residue of a carboxylic acid derived acyl group and where R.sup.5 and R.sup.6 are the same or different C.sub.1-4 alkyl or C.sub.7-10 aralkyl groups; or taken together with the adjacent nitrogen atom form a heterocyclic ring containing from 4 to 8 carbon atoms and optionally a further heteroatom selected from oxygen and nitrogen; by reacting a compound of formula (XII): ##STR2## with an amine of formula HNR.sup.5 R.sup.6, the reactant of formula (XII) being prepared by reaction of an appropriate enol derivative with a phosphorus reagent. The enamines of formula (IX) are useful in the preparation of 3-hydroxycephalosporins.
