  • Publication number: 20060135178
    Abstract: A radio frequency transmission device including electronic circuitry. A digital logic circuit is alternate-able from a sleep mode to an active mode after a pre-determined time period, and back to the sleep mode immediately after transmission of a digital signal. The digital signal includes a unique and pre-determined sequence of fixed length pulses routed to a transmission circuit to transmit a radio signal in a specific frequency range. An output display signal from the output circuitry is displayed with an LED. An input circuitry is manually activated. A radio frequency signal is received with a receiver circuitry, sensed to determine if the received signal has a compatible characteristic of an expected signal. The radio frequency signal is converted into a digital form and sent to the microprocessor. Every associated transmitter device is tracked with a counter maintained by a microprocessor. Personnel, belongings and pets can be tracked with this device.

  • Publication number: 20050073810
    Abstract: The present invention provides a locking mechanism for an external optical disk drive. The locking member is positioned on the upper housing to release or lock the cover. The cover has a projection extending downwardly from its front end and three journals are integrally formed with the cover. Three grooves are defined on the upper housing and sized to receive three corresponding journals of the cover. Besides, both ends of a resilient member are respectively adapted to be received in hubs. The resilient member is restrained by the upper housing and the hubs. Viscous material can be applied between the hubs and the shallow shaft. When the locking member disengages from the opening of the cover, the cover will be opened smoothly due to the viscosity of the viscous material.
