  • Patent number: 7134010
    Abstract: A network device is provided which includes a device input, at least one port, a frequency doubler, a data I/O device, and a programmable delay locked loop. The frequency doubler is coupled to the input and configured to receive an input signal and output an output signal having double the frequency of the input signal. The data I/O device is configured to output data based upon a reference clock signal. The programmable delay locked loop is coupled to the device input and configured to receive an input signal and to automatically output an output signal being a predetermined amount out of phase from the input signal. An external clock signal received at the device input is input to the frequency doubler. The output of the frequency doubler is input to the data I/O device as a reference clock. Data (e.g., from internal device logic) is output from the data I/O device to the at least one port.

  • Patent number: 7130995
    Abstract: A method and system for managing a secure network boot of a secondary server (server blade). The server blade sends a request, via an Ethernet switch, for a boot program to multiple Dynamic Host Configuration Protocol (DHCP) servers. One of the DHCP servers responds with an address of at least one Pre-boot Execution Environment (PXE) server that can upload a boot program to the server blade. Only if the responding DHCP server is on a list of known trusted DHCP servers will the Ethernet switch allow the server blade to receive the response from the responding DHCP server, thus allowing the download of a boot program from a PXE server.

  • Patent number: 7131011
    Abstract: A mechanism is provided for a personal computer to preserve user and system state data in the event of an AC power failure when the computer is in a standby state. When the AC power failure occurs, a switchover circuit connects a rechargeable energy storage medium, such as a rechargeable battery, to the power supply of the computer for powering components of computer, and the computer is awaken. A critical battery alarm is then issued to trigger the operating system of the computer to perform a transition into a hibernation state, during which the state data of the computer are persistently stored. The energy storage medium is disconnected from the power supply after the computer system has entered hibernation.

  • Patent number: 7127631
    Abstract: A single wire serial interface for power ICs and other devices is provided. To use the interface, a device is configured to include an EN/SET input pin. A counter within the device counts clock pulses sent to the EN/SET input pin. The output of the counter is passed to a ROM or other decoder circuit. The ROM selects an operational state for the device that corresponds to the value of the counter. In this way, control states may be selected for the device by sending corresponding clock pulses to the EN/SET pin. Holding the EN/SET pin high causes the device to maintain its operational state. Holding the EN/SET pin low for a predetermined timeout period resets the counter and causes the device to adopt a predetermined configuration (such as off) until new clock pulses are received at the EN/SET pin.

  • Patent number: 7124306
    Abstract: In a power on/off circuit apparatus, if a microcomputer malfunctions, an on/off operation of a power switch is executed, and thereby, the microcomputer is reset. A non-volatile memory stores an operating state of components just before the power switch is operated. Therefore, if the microcomputer malfunctions, without unplugging an AC cord, it is possible to reset the microcomputer by the power switch, and thus, to carry the components from a state just before the reset to the next operating state.

  • Patent number: 7124308
    Abstract: A reproduction apparatus comprising a communication unit adapted to receive digital data distributed by a distribution apparatus, a reproduction unit adapted to reproduce the digital data received by the communication unit, a prediction unit adapted to predict a reproducible time using remaining power of a battery before the reproduction apparatus requests the distribution apparatus to distribute the digital data, and a determination unit adapted to determine whether the digital data can be reproduced to the end or not based on the reproducible time predicted by the prediction unit. If the determination unit determines that the digital data can be reproduced to the end, the reproduction apparatus requests the distribution apparatus to distribute the digital data to be reproduced by the reproduction unit, and if the determination unit determines that the digital data cannot be reproduced to the end, the reproduction apparatus issues an alarm indicating that the digital data cannot be reproduced to the end.

  • Patent number: 7120815
    Abstract: Clock circuitry supplies synchronized clock waves to loads on plural integrated circuit chips. The clock circuitry couples the synchronized clock waves to regions of the chips. There is a first clock wave route in a first direction from a first chip to a second chip and a second clock wave route in a second direction from the second chip to the first chip. The routes have substantially the same geometry and are in close proximity to each other so they have substantially the same effects on clock waves propagating therein in opposite directions. A phase detector and lowpass filter on the first chip responds to (1) a clock wave source and (2) a clock wave derived on a chip other than the first chip, to supply, via a common mode line, a control for voltage controlled delays of the chips other than the third chip.

  • Patent number: 7120785
    Abstract: Improved approaches for enabling user accounts to be portable across different multi-user computer systems are disclosed. A user account created at a multi-user computer can be stored to an external, portable data store, thereby rendering the user account portable. The multi-user computer system, e.g., through its operating system, locates user accounts on not only in local storage of the multi-user computer system, but also in any removable data storage attached to the multi-user computer system. Hence, by coupling the external, portable data store to another multi-user computer, a user is able to login to any supporting multi-user computer and be presented with their user configuration and user directory. Since the data store that stores the user account is not only external but also portable, a user can simply tote the data store to the location of different multi-user computers.
