摘要： A local oscillator (LO) module comprises a local oscillator and a feedback circuit. The local oscillator, biased at a supply voltage, generates a local oscillator signal having a duty cycle. The feedback circuit makes an absolute adjustment of the duty cycle of the local oscillator signal in response to a difference between a first voltage signal, representing a voltage level of the local oscillator signal, and a second voltage signal, representing a voltage level of a portion of the supply voltage corresponding to a desired duty cycle for the local oscillator signal.

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： A system and computer program product for managing the lifecycle of an object, where the lifecycle involves a plurality of states of the object, at least one transition between the plurality of states and at least one role who has authority to execute the at least one transition. At least one of the plurality of states, the at least one transition and the at least one role is mapped to Web Ontology Language (OWL) elements. The role related control information is obtained using the reasoning ability of OWL itself according to the above mapping. Furthermore, the lifecycle is managed according to the above role related control information. Using the principles of the present invention, the access control information of roles can be embedded into the lifecycle description and therefore the lifecycle management can be realized easily.
