摘要： A femto cell at a customer premises, such as an IP-based femto Base Transceiver System (IP-BTS), can be configured as a “private access” node intended to service a limited set of mobile stations. However, mobile stations not associated with the private femto cell may acquire and lock onto the femto BTS. To avoid service blockages in such cases, the private femto BTS will allow call access attempts by, and call deliveries to, a non-associated mobile station, despite the “private access” configuration. However, upon completion of call set-up, the non-associated mobile station is directed to initiate handoff, from the private femto cell coverage provided by the femto BTS into a cell coverage of a base station of the macro network, to conserve femto cell resources for use in servicing calls of the associated mobile station(s).

摘要： Methods, devices, and systems for demolding lens mold assemblies are described in which the lens mold assemblies are positioned below a puncher header each with at least one punch pin. The puncher header is then moved against the lens mold assemblies so that the at least one punch pin of each puncher punches through a lens mold layer of a first mold part to then push against a second lens mold layer of a second mold part to separate the two parts in a demolding process.

摘要： A programming method of a programmable logic device (PLD) to enable system recovery after power failure is provided. Key configuration bits controlling output enable signals of the PLD are programmed at a different time than all other configuration bits in the PLD. If those key bits are unprogrammed, the PLD behaves identically to a fully erased device. Thus, by programming the key configuration bits after all other bits are successfully programmed, any potential damage to the system is virtually eliminated. In this manner, if the main programming sequence is interrupted, the PLD will power up with partial internal activity, but no active output signals. Moreover, even if the interruption occurs during the programming of these few bits, the result is only a partial activation of output signals which is significantly better than the activation of output signals with incorrect functions.

摘要： A programmable interconnect is provided that includes a first plurality of lines, a second plurality of lines, and means for connecting one of the first plurality of lines to one of the second plurality of lines, wherein the means for connecting includes an antifuse and a diode. The diode in this configuration performs the equivalent logical function as an AND gate. Programing the antifuse determines the diode-AND gate function performed. In this manner, a programmable interconnect array in accordance with the present invention, formed using standard fabrication processes, provides an area-efficient implementation of a wide AND functionality.

摘要： The bit line for reading data in or writing data out from a CMOS integrated circuit latch is precharged to the trip point voltage of the latch (as determined by the latch's transistor design) shortly before the occurrence of a read operation. The precharging circuitry uses the latch circuit itself to generate the trip point, hence ensuring that the precharging circuit operates properly with regards to the latch characteristics in spite of temperature, voltage and fabrication process variations. The precharging circuitry ensures that during the operation of reading data from the latch, the bit line voltage never causes the latch to completely switch states, since at most the bit line voltage asymptotically approaches the trip point voltage. The precharging circuit is relatively simple, including only two logic gates and three other transistors.

摘要： A programmable logic device is presented comprising a global interconnect array whose lines are fed via programmable multiplexers to logic array blocks. The global interconnect array lines are fed to the multiplexers in a specific pattern which maximizes the user's ability to route a selected line to the output of a selected multiplexer, while at the same time maintaining higher speed and lower power consumption, and using less chip array than prior art programmable logic devices using programmable interconnect arrays based on erasable programmable read-only memories.

摘要： A paper tray having a bottom, front and rear walls extending upwardly from the bottom, and side walls extending upwardly from the bottom to define an open boxlike structure for storage of sheets of paper in readiness for use. A paper receiver is pivotably mounted on the tray for receiving sheets of paper after printing thereof. The paper receiver has a first position in which paper can be fed automatically from the tray to a print roller and a second position in which paper can be manually fed to the print roller. In the automatic mode, the paper is fed by a drive roller to produce a buckle at its leading position to insure alignment at the print roller and subsequent straight, unskewed feed. The paper receiver carries a conveyor belt driven from the print roller at a greater linear speed to insure positive feed of the paper from the print roller to a receiving station.

摘要： A method of stopping a feedback-controlled stepping motor having a stator and a rotor wherein the drive of the stator field is leading the rotor by more than one step and the rotor is rotating with an angular velocity within a first range of values is performed by decreasing the drive lead of the stator field from its slewing value to another value whereby the angular velocity of the rotor decreases below the first range and sensing for the decrease of the angular velocity of the rotor to within a second range of values so that when the angular velocity of the rotor is within the second range of values the rotation of the stator field is stopped to brake the rotor.
