摘要： A method and apparatus for providing an oscillating signal within a transmitter/receiver circuit is described. The transmitter/receiver circuit may include an oscillator that generates an oscillating signal that may be provided to a low power, low gain mixer of the transmitter/receiver circuit along a shorter circuit path that includes low power circuitry, such as low power buffers and low power frequency dividers. The oscillating signal may also be provided to a high power, high gain mixer along a longer circuit path that includes high power circuitry, such as high power buffers and high power frequency dividers. Specifically, the low power circuitry is adapted to consume less power in an ON state than the high power circuitry in an ON state, and the shorter circuit path has a shorter electrical path length than the longer circuit path.

摘要： A transceiver for multi-standard operation (usable, for example, to communicate signals both of a first wireless communication standard and of a second wireless communication standard) has a mixer that receives a local oscillator signal generated by a local oscillator. A PLL of the local oscillator involves a VCO, a digitally programmable analog loop filter, a digitally programmable VCO supply voltage circuit, and a digitally programmable VCO varactor bias control circuit. In one aspect, the bandwidth of the analog loop filter is adjusted depending on the communication standard of the signal being communicated. In other aspects, the VCO supply voltage circuit and/or the varactor bias control circuit are configured in different ways to optimize PLL performance depending on the communication standard of the signal being communicated.

摘要： A resonator of a VCO includes a fine tuning main varactor circuit, an auxiliary varactor circuit, and a coarse tuning capacitor bank circuit coupled in parallel with an inductance. The main varactor circuit includes a plurality of circuit portions that can be separately disabled. Within each circuit portion is a multiplexing circuit that supplies a selectable one of either a fine tuning control signal (FTAVCS) or a temperature compensation control signal (TCAVCS) onto a varactor control node within the circuit portion. If the circuit portion is enabled then the FTAVCS is supplied onto the control node so that the circuit portion is used for fine tuning. If the circuit portion is disabled then the TCAVCS is supplied onto the control node so that the circuit portion is used to combat VCO frequency drift as a function of temperature. How the voltage of the TCAVCS varies with temperature is digitally programmable.

摘要： A luggage cart includes a supporting tray and a latching mechanism. The latching mechanism includes a top seat, a fastening member, an actuating member, a bottom seat fixed to the supporting tray, and a latch bolt. The fastening member has a flange cap portion adapted for securing to a luggage container, and a shaft portion formed with a first locking part. The latch bolt is mounted to the bottom seat and is slidingly engaged with the actuating member. The actuating member is movable to move the latch bolt from a locking position, where the latch bolt engages the first locking part of the fastening member, to an unlocked position, where the latch bolt is disengaged from the first locking part to permit removal of the fastening member.

摘要： The invention relates to a method for preparing silica modified by a silane coupling agent. The method comprises the following steps: preparing a kind of coupling agent sol solution by mixing the solvent, water, catalyst and coupling agent; uniformly dispersing silica into the sol solution by means of ultrasonic dispersion or shear dispersion to achieve a turbid solution with uniform dispersion and ideal particle size; and then stirring the turbid solution at a constant speed to make the coupling agent sol reacting with silica to prepare highly hydrophobic silica modified by the coupling agent through controlling the temperature and reaction time. The coupling agent sol solution is obtained by a sol-gel process and silica is uniformly dispersed in the coupling agent sol solution through combined action of various dynamic means to ensure the sufficient reaction between silica and coupling agent, thus to obtain silica modified by the coupling agent.
