Abstract: An intelligent lithium-battery-activating charging device is connectable between a charging power source and an application electrical device and contains an internal circuit that builds up a charging/discharging mode to correspond the charging power source to a lithium battery accommodated in the application electrical device. After a short time period of charging, which is short enough that the voltage detection circuit inside the application electrical device cannot properly respond, a time period of discharging follows and then discharging is stopped, so that the detection performed by the voltage detection circuit is delayed until the cycles of short time period charging and discharging are completed. If the detection shows the battery is not fully charged, then the charging operation starts again. During the charging process, ions are moved in one direction in one moment and then reversed in the next moment so that built up of deposition on electrodes can be avoided.

Abstract: An air compressor includes a chassis that supports thereon a motor, a transmission set, and a plurality of extendible barrels. The transmission set includes a clutch that is operatively coupled to the motor through a belt. Two eccentric rotation members are respectively arranged on opposite sides of and coupled to the clutch. Each eccentric rotation member is coupled to a crank arm, which has a moving end connected to the extendible barrel. The extendible barrel is provided with an air inlet port and an air outlet port. When the motor is set in operation, the transmission set drives the extendible barrels to move carry out reciprocal and axial compression to delivery compressed air. The present invention features easy maintenance and can carry out a noise-free operation.

Abstract: A tidal power generation device includes at least a chassis, a rail frame, and a chain support rack. A driver is provided at an end of the rail frame. The driver includes a connection bar. The chain support rack is set on the chassis and includes toothed wheels that support and operatively couple a chain that is coupled to the connection bar. One of the toothed wheels has a shaft that is supported by a one-way bearing and is operatively coupled to a first transmission axle by mated gears. The first transmission axle drives a second transmission axle, which is coupled to a dynamo. The driver is caused to move frontward by sea waves for driving the first transmission axle through the chain and the toothed wheels, so as to cause the rotation of the second transmission axle for transmitting torque to the dynamo to generate electricity.

Abstract: A current protection device comprises a substrate having an upper portion and a lower portion; a fusing layer installed between the upper portion and the lower portion; ends of the fusing layer exposed from the substrate; a cavity formed near surfaces of the fusing layer for providing a space to receive the fusing layer as the fusing layer fuses; and an end electrode having three layers including a silver thin layer, a nickel thin layer and a tin thin layer; the end electrode being formed as a conductive electrode. The method for forming the same is provided.

Abstract: A computer mouse with retractable cable is disclosed. The internal of the computer mouse contains coil spring, reeling disc, positioning bead and conductors. The lead wire once pulls, it is positioned and a second pull will restore back to its original position. The pulling of lead wire controls the required length of the mouse.

Abstract: A hot-plugging connector is provided for a hard disk drive (HDD), including an HDD plugging port and a connection port for an SATA cable and a power supply and further includes an HDD plugging indication device having a positive terminal that is supplied with power from a host machine and a negative terminal that is connected to a pin of the connector that is in connection with ah HDD plugging grounding line but is not in direct connection with a grounding line of the host machine. The hot-plugging connector further includes an HDD operation indication device having a positive terminal that is supplied with power from a host machine and a negative terminal that is connected to a pin of the connector that is in connection with an HDD operation grounding line but is not in direct connection with a grounding line of the host computer.

Abstract: An adaptation device includes a lower casing member including a connection interface and forming a bottom slot in a front bottom, at least one retention flange on side walls, and pivot receiving holes in rear portions of the side walls. A retention board forms a connection interface receiving opening in a front end, rotation shafts on a rear end, and pawls on a bottom. The shafts are movably received in shaft slots defined in a rotary board. Pivots are formed below the shaft slots for being received in pivot receiving holes defined in the lower casing member. The rotary board has a hold-down plate. With a hard disk drive placed on the retention board and connected to a connection interface, the cover and the rotary board are closed forward to have the hold-down plate holding down the hard disk drive. The cover is then moved backward for fixation.

Abstract: An antenna device includes an enclosure defining a receiving compartment and having a back forming a mounting seat for mounting to a fixture and an end forming a connector for connection with a coaxial cable. A reflection case, which is received in the enclosure, includes reflection plates set around the case and has a bottom stamped to form partially cut tabs that are bent upward by an angle of approximately 90 degrees. The diamond-shaped antenna is composed of two quadrilateral antenna boards received in the reflection case and fixed to the bent tabs and has a central portion to which a waveguide is coupled for connection with the connector of the enclosure through a coaxial cable. The enclosure is closed by a cover plate to protect the diamond-shaped antenna from direct exposure to severe weather.

Abstract: The ticket processing system utilizes RFID technique to record and access data in the parking tickets. The ticket processing system mainly contains at least a ticket reader positioned at the entry of the parking lot. A first antenna in the ticket reader writes data into a ticket having RFID chip and a second antenna at a ticket retrieval opening of the ticket reader erases data from the ticket. The ticket processing system further contains a number of third antenna at the various parking spots which records a spot number into the ticket to facilitate the later locating the whereabouts of the parked vehicle.

Abstract: A transmission cable assembly is connected between an ignition coil and a spark plug to transmit a high voltage generated by the ignition coil to the spark plug for ignition of a fuel-air mixture. The transmission cable assembly includes a transmission cable and a grounding unit. The transmission cable includes a high-voltage wire for transmission of high voltage and an insulation jacket wrapped around an outside surface of the high-voltage wire. The grounding unit is made of an electrically conductive substance and includes a grounding layer and multiple grounding wires. The grounding layer completely covers and tightly engages the insulation jacket. The grounding wires each have an end connected to an inside surface of the grounding layer.
