    摘要: A method of implementing a time base change to a time-division multiplexec bitstream, for example an MPEG-2-compatible bitstream. The time base change is in response to a Time Base Change Flag. The bitstreams have video and audio packetized elementary streams, and each of these streams has a common time base. Each of the packetized elementary streams has a packet header, and packet data. The packet headers of the packetized elementary streams each contain a Presentation Time Stamp/Decoding Time Stamp flag field, a Presentation Time Stamp field, and a Decoding Time Stamp field. A time base change is indicated by a change in the PCR. The first step in changing the Time Base is receiving a discontinuity in the bitstream. This is used to disable synchronization of the video and audio bitstreams, and to mark a data byte in the bitstream associated with the Time Base Change Flag. The time base change is carried out and an interrupt is issued when the marked data byte arrives for decoding. This interrupt re-enables synchronization of the audio and video bitstreams.

    摘要: A tape feeder 200 includes a sprocket 201 having a plurality of teeth 202 for engaging holes of a tape. A pawl 205 engages selected teeth of sprocket 201. A first lever 203 is coupled to pawl 205 and a second lever 204 is coupled to first lever 203 and a source 208 of a driving force.

    摘要: A dual-pawl ratchet wrench mechanism is disclosed having a stop mechanism for limiting over-travel of a reversing lever for selecting drive directions. The stop mechanism is formed on a disc is selectively engageable with first and second pawls to move the pawls into and out of engagement with a ratchet gear to determine a torque drive direction, the ratchet gear capable of providing torque to a working piece in the selected drive direction. The design simplifies manufacturing. Additionally, the reversing lever is assembled with the mechanism in a manner to improve sealing.

    摘要: A dual-pawl ratchet wrench mechanism is disclosed having a stop mechanism for limiting over-travel of a reversing lever for selecting drive directions. In one form, the wrench mechanism includes a ball and spring assembly that cooperate with recesses to define proper positions for the reversing lever, and one or more ramps are provided between the recesses to promote tactile feel and to promote the reversing lever being rotated to a proper position. In some forms, the stop mechanism is formed on a stationary portion, such as a spacer or the wrench body, and a portion of the reversing lever. The design simplifies manufacturing, such as by simplifying assembly and minimizing the need for securements. Additionally, the reversing lever is assembled with the mechanism in a manner to improve sealing.

    摘要: A bi-directional, out-of-plane electrostatic comb drive apparatus including two electrically independent sets of stator comb tines; and a method for fabricating an out-of-plane comb drive with stacked sets of stator comb tines. A first set of stator comb tines is offset from a second set of stator comb tines. A set of rotor comb tines interleaves with both sets of stator comb tines. A first voltage applied to the first set of stator comb tines operates to pull the rotor tines toward the first set of stator comb tines. A second voltage applied to the second set of stator comb tines operates to pull the rotor tines toward the second set of stator comb tines, enabling bi-directional operation. A fabrication method is disclosed that enables fabrication of the first and second sets of stator comb tines that are mechanically and electrically independent and interleaved by the rotor comb tines.
