    摘要: A method, apparatus and system provide for efficient use of communication resources for providing broadcast services in a communication system. A receiver receives a first broadcast controller identification from a first base station, and a second broadcast controller identification from a second base station. A controller coupled to the receiver determines whether the first and second broadcast controller identifications are associated with use of a common set of broadcast parameters. A transmitter transmits a request for transmission of a new set of broadcast parameters when the first and second broadcast controller identifications are not associated with use of the common set of broadcast parameters. After receiving the new set of broadcast parameters, the receiver uses the new set of broadcast parameters for receiving broadcast services.

    摘要: An optical lithography method is disclosed that uses double exposure of a reusable template mask and a trim mask to fabricate regularly-placed rectangular contacts in standard cells of application-specific integrated circuits (ASICs). A first exposure of the reusable template mask with periodic patterns forms periodic dark lines on a wafer and a second exposure of an application-specific trim mask remove the unwanted part of the dark lines and the small cuts of the dark lines left form the rectangular regularly-placed contacts. All contacts are placed regularly in one direction while unrestrictedly in the perpendicular direction. The regular placement of patterns on the template mask enable more effective use of resolution enhancement technologies, which in turn allows a decrease in manufacturing cost and the minimum contact size and pitch. Since there is no extra application-specific mask needed comparing with the conventional lithography method for unrestrictedly-placed contacts, the extra cost is kept to the lowest. The method of the invention can be used in the fabrication of standard cells in application-specific integrated circuits (ASICs) to improve circuit performance and decrease circuit area and manufacturing cost.

    摘要: A focus adjusting mechanism (50) for use in a portable electronic device (100) with a lens module (40) is provided. The lens module includes a lens barrel (42) and a lens barrel holder (44). The lens barrel is threaded into the barrel holder. The focus adjusting mechanism includes a driving member (52), a follower (54) and a transmission rod (56). The driving member has a plurality of circumferential teeth (5242) formed thereon. The follower has a plurality of linear teeth (5472) formed thereon. The linear teeth engage with the circumferential teeth for transforming the rotation of the driving member to the linear movement of the follower. The transmission rod is disposed between the follower and the lens barrel to transform the linear movement of the follower into the rotation movement of the lens barrel relative to the lens barrel holder.

    摘要: Various techniques for synchronizing illumination with an audio signal are disclosed. According to one aspect of the techniques, an audio signal continuously is received and processed one phase or period at a time in an analyzing or detecting unit. From one phase of the audio signal, a set of light controlling parameters are determined from a look-up-table. These light controlling parameters are used to adjust duty cycles of square waves used to drive a plurality of light sources such that the illumination produced is in accordance with the audio signal.

    摘要: A method is provided for securing a PMIP tunnel between a serving gateway and a new access node through which an access terminal communicates. A PMIP key hierarchy unique to each access terminal is maintained by the gateway. The gateway uses a first node key to secure PMIP tunnels when authentication of the access terminal has been performed. A PMIP key is generated based on the first node key and the PMIP key is sent to the new access node to assist in establishing and securing a PMIP tunnel between the gateway and the new access node. Otherwise, when authentication of the access terminal has not been performed, the gateway generates a second node key and sends it to an intermediary network node which then generates and sends a PMIP key to the new access node. This second key is then used to secure the PMIP tunnel.
