  • Publication number: 20120111638
    Abstract: An earth boring drill bit designed for a specific performance, within a finished product tolerance, using components built to a looser manufacturing tolerance. The bit may be assembled by selecting a leg from a plurality of pre-manufactured legs; selecting a bit body from a plurality of pre-manufactured bit bodies, the bit body having a slot for receiving the leg; placing the leg within the slot; and fixing the leg within the slot within the finished product tolerance by placing one or more shims between the leg and the slot. The shims may be used to adjust an axial position, a radial position, and/or a circumferential position of the leg with respect to the slot. The leg and the bit body may be selected, or produced, to ensure the bit will not meet the specification, given the manufacturing tolerance, without the shims.

  • Publication number: 20120114026
    Abstract: An apparatus interfaces a commercial-off-the-shelf (COTS)/off-the-shelf (OTS) modem for pulsed data communication using existing sensor aperture among radar platforms. The apparatus includes a demodulator for receiving a sequence of first pulse signals, at least one first pulse signal of the sequence of first pulse signals being modulated with an input signal. The demodulator includes a pulse regeneration module for regenerating a pulse timing of the sequence of first pulse signals and a pulse demodulation module for demodulating the sequence of first pulse signals to recover the input signal in synchronization with the pulse timing of the sequence of first pulse signals.

  • Patent number: 8176339
    Abstract: A method and system for managing peripheral connection wakeup signaling in a processing system supporting multiple virtual machines provides a mechanism by which ownership of a peripheral having system wakeup capability is transferred between virtual machines. The power management event signal is connected to a service processor input that in turn signals a hypervisor to direct the wakeup activity to a particular logical partition in which the virtual machine was last executing. The hypervisor can then determine whether or not to wake up the entire system, or portions thereof and can direct the power management event to the appropriate virtual machine. In particular the peripheral may be an Ethernet adapter supporting Wake-On-LAN capability. State initialization, which is typically ensured by system power cycling is provided instead by controlling power to the standby power source or in some instances by forcing an indication of a disconnect/reconnect of the wakeup signaling connection.

  • Patent number: 8173012
    Abstract: A vertical flexible oil flow director hose is used to recover, to guide, and to filter the spilled oil from its source beneath the sea floor to the surface of water and to accumulate the floating oil therein for being ready to be pumped into an oil tanker. The said hose extends in the sea all the way from the sea floor to the surface of water by connecting its lower end to a circular sinking weight block and its upper end to a hollow doughnut-shaped floating device. The said hose includes two main portions abutting each other, the lower portion is for guiding and displacing water out through the gaps or meshes. The upper portion is for continued guiding and accumulating the oil in its upper section. A gas-tight dome cap having an opening at its bottom may be used to cap the upper opening of the oil accumulator well in the floating object, for holding the gas as necessary. A gas-compressor and gas tank or tanks will be equipped on the oil tanker ready to take and to store the gas.

  • Patent number: 8174785
    Abstract: This application discloses a hard disk drive using a self-resonant frequency band of a Voice Coil Motor far above its operational frequency band to predict Rapid Off Track events before its head stack assembly can deliver the disruption to the slider writing a track. A circuit board and/or an integrated circuit are disclosed in various embodiments to predict the ROT events using the self-resonant frequency band and/or to respond to the prediction to suppress the slider writing.

  • Patent number: 8174041
    Abstract: A lighting unit comprises a packaging substrate (10) formed from a semiconductor, a channel (12) formed in the substrate and a discrete light emitting diode arrangement (34) in the channel. A surface region of the channel comprises doped semiconductor layers (20, 24) which define a light sensor. The arrangement provides a light sensor (which can be used to determine colour and/or output flux) for a LED unit, with the light sensor embedded in substrate used for packaging. This provides a low cost integration process and provides good registration between the light sensor and the LED output.

  • Patent number: 8174892
    Abstract: A method of reading sequential pages of flash memory from alternating memory blocks comprises loading data from a first page into a first primary data cache and a second page into a second primary data cache simultaneously, the first and second pages loaded from different blocks of flash memory. Data from the first primary data cache is stored in a first secondary data cache, and data from the second primary data cache is stored in a second secondary data cache. Data is sequentially provided from the first and second secondary data caches by a multiplexer coupled to the first and second data caches.

  • Publication number: 20120104295
    Abstract: A device for controlling an actuator includes an input interface that receives a plurality of input signals including a setpoint command signal and a feedback signal. An output interface provides a drive signal to the actuator. First, second, and third redundant loop controllers processes the setpoint command signal and the feedback signal to generate respective actuator control signals. A primary controller compares the actuator control signals to determine whether at least two are substantially similar. The device outputs the drive signal to the actuator according to an actuator control signals that has been determined by the primary controller to be substantially similar to another. Any one of the redundant loop controllers is hot swappable with a replacement loop controller such that loop controller redundancy is operatively maintained by the device in controlling the actuator while one of the redundant loop controllers is hot swapped.

  • Publication number: 20120106953
    Abstract: Dual laser-power-level control and calibration system for burst-mode and continuous-mode transmitter. A first signal path receives a transmit signal that also drives the transmit laser, and a second signal path receives the output of a monitor diode. The first and second signal paths include filtering so that the two signal paths have a similar frequency response. The upper and lower excursions in both signal paths are compared, and the power levels of the optical transmitter are adjusted based on those comparisons. Embodiments with one control loop and two control loops are disclosed.
