Title: Power conservation based on hard disk rotational inertia
Inventor: KARDACH JAMES
IPC: G11B19/28
Filed: 2013-06-25
Abstract: Various embodiments are generally directed recurringly cycling the driving of a platter media of a hard drive with a motor, allowing rotation of the platter media to slow only to a threshold rotational speed to balance power conservation with delays in accessing data. A method comprises driving platter media of a hard drive to rotate at a selected normal rotational speed, retrieving data stored on the platter media when the platter media rotates at the normal rotational speed, ceasing to drive the platter media to rotate to allow the platter media to rotate under rotational inertia imparted to the platter media, monitoring a current rotational speed of the platter media, and resuming driving the platter media to rotate based on the current rotational speed falling to a lower threshold rotational speed selected to be less than the normal rotational speed. Other embodiments are described and claimed.

Title: Condition monitoring method and apparatus for high-voltage AC electrical systems
Inventor: Riccardo Giussani
IPC: G01R31/12
Filed: 2015-12-07
Abstract: A method for monitoring partial discharge activity in an alternating-current system, for example a variable-speed drive motor, comprises: obtaining a high-frequency signal in a conductor originating from partial discharge activity; sensing a low-frequency AC waveform 38 in the same conductor, and; capturing the digitized high-frequency signal as consecutive data blocks, capture being triggered by a timing signal 34 derived from the low-frequency waveform e.g. as shown in the figure, where comparator 42 detects zero-crossings. A phase-resolved partial discharge pattern may then be produced from the digitized data. A low-pass filter for the low-frequency signal may have an upper cut-off of at least 75Hz; the bandwidth of a winding which may obtain the high-frequency signal may have a lower cut-off of 1MHz. Also claimed is a sensor unit comprising a split-core current transformer with high and low frequency windings, sensing pulses in a high-voltage cable originating from partial discharge.

Title: Communication apparatus, control method, and program
Inventor: TAKESHI MATSUSHITA
IPC: H04W84/18
Filed: 2015-06-02
Abstract: A communication apparatus connects to a target device using a first communication method which may be, for example near field communication (NFC) or Bluetooth (RTM). The apparatus acquires communication information of a target apparatus through this communication link. It determines whether or not the target apparatus is connected to an access point to which the communication apparatus is connected. If it is determined that the target apparatus is not connected to the access point to which the communication apparatus is connected, the communication apparatus connects to the target apparatus using a second communication method (for example Wi-Fi Direct), different from the first communication method, to establish a direct communication link. If it is determined that the target apparatus is connected to the access point to which the communication apparatus is connected, the communication apparatus connects to the target apparatus via an access point using the second communication method (for example Wi-Fi). The embodiment describes setting up a peer-to-peer link between a mobile device and a wireless printer.

Title: Video data processing system
Inventor: DOMINIC HUGO SYMES
IPC: H04N19/513
Filed: 2017-03-15
Abstract: An apparatus and method for encoding frames of a source frame sequence of video image data includes circuitry 8 encoding source frames using reference frames 13 (e.g. downscaled), 14 (e.g. full resolution), and monitoring circuitry 15 configured to, when the encoding circuitry 8 is encoding a source frame using reference frame(s) 13, 14, monitor memory bandwidth being used. In response to the monitored memory bandwidth being greater than a threshold, the encoding circuitry is controlled to encode a subsequent part of the source frame using a modified video encoding process to restrict the memory bandwidth usage when using one or more reference frames 13, 14 when encoding a subsequent (remaining) part of a source frame. The threshold may be based on a target memory bandwidth used for encoding the whole source frame. A memory bandwidth measure may be based on data read from a cache and/or into the cache from a memory when using reference frames; a moving average or accumulated total of cache/memory accesses may be assessed. Reference blocks may be used. The modified encoding process may restrict the number of reference frames used, frame search area size, or search position.

Inventor: DARRAN MICHAEL HANDSHAW
IPC: G06K7/10
Filed: 2017-07-04
Abstract: An imaging sensor of an imaging reader senses return light from a target to be read by image capture 10 along an imaging axis 18 over a field of view that extends along mutually orthogonal, horizontal and vertical axes. Two aiming light assemblies are offset from the sensor, and direct an aiming light pattern at the target. The pattern has an aiming mark 60 in a central area of the pattern, and a pair of aiming light lines 50 that are collinear along the horizontal axis. The visibility of the aiming mark is enhanced by optically configuring the aiming mark to be different in brightness relative to a remaining area of the pattern such as by specially configuring aiming lenses 44 with regions of different optical power to form each aiming light line of non-uniform brightness. The aiming mark of enhanced visibility constitutes a prominent visual indicator of a center zone of the field of view.

Patent GB-2586081-A (GB)
Title: Signal processing
Inventor: JOHN KEITH SHEARD
IPC: G01C19/5776
Filed: 2019-08-02
Abstract: A method of demodulating a MEMS sensor pickoff signal from a vibrating resonator of said sensor, the method comprising: sampling the pickoff signal with an asynchronous ADC at a sampling rate of at least 50 times the resonant frequency of the resonator to generate a stream of samples; generating a first value by combining samples from said stream of samples according to a selected operation, said operation being selected in dependence on a synchronous clock signal that is synchronous to the resonant frequency of the resonator, said synchronous clock signal having a frequency at least twice the resonant frequency of the resonator; and counting the number of samples contributing to the first value. The increased sampling rate of the pickoff signal allows a much higher number of samples to be taken into account, thereby reducing noise. However, the ADC is not driven by a synchronous clock, but instead operates asynchronously from the resonator of the MEMS sensor. A lower frequency synchronous clock is used to keep track of which samples fell within particular sectors of the resonator cycle. This information can then be used to select an appropriate way to combine the samples.
