摘要： The invention provides a method of manufacturing a user equipment comprising a wireless modem, a method of activating a user equipment as a wireless modem, and a corresponding server and user equipment. A processor is produced for executing wireless modem code to operate the processor as a wireless modem, the processor having a writeable, non-volatile memory for storing the wireless modem code but being produced with at least a substantive portion of said wireless modem code not installed on said memory or otherwise, thus rendering the processor inoperative as a wireless modem. The processor is assembled into a user equipment and supplied to an end-user still without the substantive portion of wireless modem code installed. In response to an indication from the end-user requesting activation of the user equipment as a wireless modem, at least said substantive portion of wireless modem code is then distributed to the end-user for installation on the memory the user equipment's processor.

摘要： A logic circuit latch including an input stage for receiving a logical input signal and a pair of differential amplifiers, each having an input operatively coupled to the input stage, and at least one of them having an output arranged to supply the logical output of the latch. Each of the differential amplifiers includes a transistor connected as a load, and an output of each of the differential amplifiers is coupled to bias the load transistor of the other differential amplifier. If the latch switches from the transparent state to the closed state while the logical input signal is transitioning between logical levels, the differential amplifiers drive up the logical output of the latch if the logical input signal transitions from a first to a second logical level, and drive down the logical output of the latch if the input signal transitions from the second to the first logical level.
