  • Publication number: 20080291172
    Abstract: A keyboard type input device used in conjunction with a wristwatch or a portable telephone has multiple key positions provided as character entry keys. Each key corresponds to one key in the selected row of the conventional QWERTY keyboard. A second set of control buttons provide for the selection of which row of a conventional QWERTY keyboard are represented by the character keys in addition to other functions such as case shift, and alpha-numerical control functions. A selected row is shown on a display, as visual feedback. Alternatively the keys are implemented as LCDs with pressure sensors and the characters of the selected row are displayed directly on the corresponding key positions. The keyboard finds particular use in portable devices as it demands less space than traditional keyboards.

  • Publication number: 20070294551
    Abstract: A wireless remote control circuit with dual processing units and a method is provided, which includes a signal receiving unit, a first and a second processing unit. The first processing unit is connected to the signal receiving unit and switches between an activation mode and a sleep mode at a predefined time. The second processing unit is connected to the first processing unit and is preset in the sleep mode. The first processing unit provides a voltage to activate the signal receiving unit during the activation mode, and transmits a resume signal after obtaining a control signal. Then, the second processing unit enters an activation mode after it receives the resume signal, and enters the sleep mode again after its internal logic circuit completes its operation, so as to reduce the complexity of using a single processing unit to design a circuit and avoid huge power consumption of the circuit.

  • Publication number: 20070211783
    Abstract: An infrared thermometer includes a thermal conductor and a thermal adjuster to conduct suitable thermal flux into the sensor unit. A thermal conductive bushing is also mounted under the bottom of the sensor unit and touching the thermal conductor. The thermal fluxes conducting to the upper portion and the lower portion of the sensor unit are thus balanced suitably and quickly to remove the thermal noise and help the thermometer maintaining precise measurements from infrared radiation of the target.

  • Patent number: 6725385
    Abstract: A device connected to an interface has operational logic and power control logic. The device further has multiple power modes, including a first mode and a second, lower power mode. In the first mode, the operational logic is coupled to the interface, and is able to communicate over the interface. In the second mode, the power control logic is coupled to the interface, and the operational logic is decoupled, and substantially powered down. This provides a low interface power mode. In this mode, the power control logic monitors the interface for command activity. The power control logic returns the device to the first mode when the device must be in the first mode to process or reply to the command. The power control logic thus provides for the restoration of function from a low interface power mode without the need for a special “wake-up” command, thereby making the low interface power mode transparent to the host.

  • Publication number: 20020192289
    Abstract: A method is disclosed for cancer treatment based on using a solid polymer gel to completely block blood vessels of tumor. A polymer aqueous solution is injected into blood vessels and formed a solid gel in blood vessels of tumor by applying electromagnetic radiation or temperature source at tumor tissue to inducing crosslinking or phase transition. The tumor cells starve and perish because of without nutrients and oxygen provided by vascularization and metastasis can also be prevented because polymer gels blocks tumor cells to shed into blood circulation, when the blood vessels of tumor are completely blocked by the solid polymer gels. Also, anti-cancer drug including chemotherapy drug, radiation drug or anti-angiogenic drug can be mixed or conjugated with the polymer in polymer aqueous solution to be locally delivered to the tumor after polymer gel formation in the blood vessels of tumor of human or animal.
