摘要： Disclosed a transmission apparatus in a CDMA mobile communication system. Transmission frames each have a plurality of time slots, and each of the time slots includes two data parts having the same length, a midamble intervening between the data parts, and a guard period for dividing the consecutive time slots. The transmission apparatus modulates the frames into a radio signal with a modulation signal and transmits the modulated radio signal using a plurality of antennas. A power amplifier amplifies the radio signal. A controller generates a switching control signal in a guard period of time slots of a frame associated with the radio signal amplified by the power amplifier. A switch switches the amplified radio signal from the power amplifier between a first and a second antenna in response to the switching control signal.

摘要： A circular stapling instrument (100) includes a casing (110), an anvil assembly (112), a staple driver (156) and a locking mechanism. The anvil assembly (112) is configured to move back and forth between an open position away from the casing (110) and a closed position adjacent the casing. The staple driver (156) is configured to move within the casing from a pre-fired position to a fired position. The locking mechanism is configured to, whenever the anvil assembly (112) is in the open position, automatically lock the staple driver (156) in the pre-fired position preventing the staple driver from being moved to the fired position. The locking mechanism is also configured to, whenever the anvil assembly (112) is in the closed position, automatically unlock the staple driver (156) from the pre-fired position to allow the staple driver to be moved to the fired position.

摘要： Communications systems are disclosed having a transmitting apparatus for transmitting a signal to a receiving apparatus, the transmitting apparatus comprising transmitting means for transmitting a plurality of directional transmission beams to the receiving apparatus via different transmission paths, each transmission beam carrying a transmission signal. The transmitting apparatus may include coding means (58) for coding the transmission signals carried by the transmission beams, the coding means (58) being arranged to code the transmission signal carried by one transmission beam differently from the transmission signal carried by another transmission beam. The transmitting apparatus may receive a feedback signal (122) indicating the quality of the various transmission beams and transmit a data signal only in selected transmission beams. A time advance may be selectively applied to some of the transmission signals so that the transmission signals arrive at a receiving apparatus in time synchronism.
