  • Patent number: 8208961
    Abstract: A system for operating at least two subscriber identity cards has a subscriber identity module (SIM) controller generating a first voltage variable signal with a first voltage level to a first subscriber identity card during a first time period, generating the first voltage variable signal at a second voltage level to the first subscriber identity card during a second time period, receiving a first code indicating that generated voltage matches from the first subscriber identity card during the first or second time period, generating a first operating voltage with the first voltage level to the first subscriber identity card when receiving the first code in the first time period, generating the first operating voltage with the second voltage level when receiving the first code in the second time period.

  • Patent number: 8121643
    Abstract: A system for initiating operating voltages for subscriber identity cards is provided. The system includes a first subscriber identity card, a second subscriber identity card, an RF module, a controller and a Baseband unit. The controller initiates a first operating voltage of the first subscriber identity card and initiates a second operating voltage of the second subscriber identity, respectively. The Baseband unit cooperates with the first subscriber identity card to camp on a first cell and cooperates with the second subscriber identity card to camp on a second cell via the RF module.

  • Publication number: 20070100291
    Abstract: A safety syringe includes a barrel, a needle hub, a plunger, an elastic piston, and a pushing member. The barrel has a shoulder. The needle hub extends from the shoulder of the barrel, and is provided with a first engaging member. The plunger extends into the barrel, and is provided with a second engaging member. The piston is sleeved on the plunger, is disposed rearward of the second engaging member, is received in and is in frictional contact with the barrel, and has a hollow body, and a restricting member that extends radially and inwardly from the hollow body. The pushing member extends radially from the plunger. The plunger is movable together with the piston relative to the barrel to a first position, and is movable relative to the piston from the first position to a second position.

  • Patent number: 5771516
    Abstract: An exchange power hand tool includes a power section having a motor encased in a housing and two tool sections, respectively serving as a wrench and a jack actuator, alternately and exchangeably engageable with the power section to be driven thereby so as to provide one power hand tool with two functions. The power section has an output pinion mounted on the motor spindle to be engageable by a driving gear chain of the tool sections for transmission of torque from the power section to the tool section for selectively performing wrenching operation or jack actuation.

  • Patent number: 5740892
    Abstract: A torque transmission mechanism to be used in a power wrench includes a body driven by a motor, having a central bore to rotatably support therein a toothed end of an output shaft. The toothed end of the shaft has a pair of diametrically opposite teeth, each defined by two circumferentially opposite contact faces that extend along radii of the output shaft. The body has a radial notch communicating the bore with a coupling member pivotally received therein. The coupling member has two opposite wings alternately movable into the bore with the rotation thereof to selectively engage one of the teeth for driving the shaft. A centrifugal clutch is provided between the body and the motor to control the movement of the wings.

  • Patent number: 5566181
    Abstract: A radio communication system (200) employs a method (400) and system (200) for establishing a communication between communication units (212-217) using geographically distributed packet duplicators (203-205). The communication system (200) includes a system controller (201), a plurality of packet duplicators (203-205), a plurality of base sites (207-210), and a plurality of communication units (212-217). The packet duplicators (203-205), which provide interconnectivity between the base sites (207-210), are distributed throughout geographic regions (233-234) of the system (200). When the system controller (201) receives a request to communicate from one communication unit (e.g., 212) in a group of communication units (e.g., 212-215), the system controller (201) selects a packet duplicator (e.g., 203) serving a geographic region (e.g., 233) containing at least one communication unit in the group and uses the selected packet duplicator (203) to establish the group communication.
