  • Patent number: 9553448
    Abstract: A system is described that turns off a high power, power supply when a device no longer needs high power. A low power, power supply or a rechargeable battery provides power to determine when the device again needs high power. The low power supply consumes a minimum possible power when the device does not need high power and the power rechargeable battery is not charged. That is, the high power and low power, power supplies are turned on or off based on the real time power consumption need of the device and the charged state of the battery. The power need of the device is monitored by a current shunt monitoring circuit and a control signal monitoring circuit.

  • Publication number: 20160366192
    Abstract: Automatically configuring a portable electronic device for accessing a site on a public network is disclosed. The method and system include establishing a connection to at least one server for establishing and maintaining website accounts, and sending information uniquely identifying the electronic device to the at least one server. The at least one server sends user account information to the device, including an account ID and password, created based on the electronic device information. The user account information is stored on the device for use the next time the device accesses the website, whereby the user does not have to enter account information in order to establish the ISP connection or the website account before accessing the public network or, if the user account is not completely set up, to establish the user account a next time the device connects to the at least one server.

  • Patent number: 9277613
    Abstract: Method and means for driving one or more LEDs. The method includes turning a power switch on to provide current through an inductor and the power switch, measuring voltseconds of the LEDs at a cycle time, comparing the measured voltseconds to a reference signal at an end of the cycle time, generating a signed discrete logical signal based on a difference between the measured voltseconds and the reference signal, and generating a control signal using the signed discrete logical signal to regulate a peak current through the power switch by keeping the cycle time voltseconds substantially constant. The reference signal may be proportional to a set average LED voltage.

  • Patent number: 5351446
    Abstract: Ingot-type semiconductor single crystals having diameters of more than 200 m can be sawed into thin wafers using an annular saw if the crystal is fed towards the cutting edge of the annular saw while rotating around its longitudinal axis. The method includes having a wafer sawed out in this way until a residual joint is created between a wafer and the end face of the ingot. Ingot and wafer are finally separated by means of a residue separation technique which leaves behind various central material projections on the ingot and the wafer. Particularly suitable for residue separation are torsion separation and separation by a wire saw. This procedure reliably prevents the frequently observable, uncontrollable breaking-off of the wafer in the final phase of the annular sawing if this is exclusively used as the method of separation.
