Abstract:
An electric lock system includes an electrically locking device including a memory unit, a first communication unit, an electric lock and a first processing unit, and a wireless communication device including a second communication unit, a second processing unit, and a second input unit. The memory unit stores an unlock code, a request code and a message. The first processing unit compares an input code with the request code and controls the first communication unit to transmit the message to the communication device if the input code matches the request code. The second processing unit controls the second communication unit to transmit an unlock request code to the first communication unit according to the message received by the second communication unit. The first processing unit compares the unlock request code with the unlock code, and unlocks the electric lock if the unlock request code matches the unlock code.
Abstract:
An electronic still camera is adapted for use with a portable computer which has a computer housing formed with a battery receiving chamber for receiving removably a battery pack therein, a power supplying device, and a set of first battery charging contacts mounted in the battery receiving chamber for connecting electrically the battery pack to the power supplying device so as to permit recharging of the battery pack when the power supplying device is active, and so as to enable the battery pack to supply electrical power to the portable computer when the power supplying device is inactive. The electronic still camera includes a camera housing having a size and shape conforming to the battery receiving chamber so as to be received removably therein, a rechargeable battery unit for supplying electrical power to the electronic still camera, and a set of second battery charging contacts for contacting the first battery charging contacts when the camera housing is received in the battery receiving chamber so as to permit recharging of the battery unit by the power supplying device when the power supplying device is active.
Abstract:
An embedded heat dissipating device mounting structure including a housing for an electronic instrument, the housing having an opening and two parallel side boards perpendicularly raised from the periphery of the opening at two opposite sides, a heat dissipating device mounted in the opening of the housing and secured to the parallel side boards and operated to carry heat out of the housing, the heat dissipating device having a cover shell which has backward springy hooks adapted for hooking on the parallel side boards of the housing at an inner side, and elongated flanges adapted for stopping against the parallel side boards of the housing at an outer side.
