Title: Receiver and method of receiving
Inventor: SAMUEL ASANGBENG ATUNGSIRI
IPC: H04L27/26
Filed: 2015-07-22
Abstract: A receiver to detect and recover payload data received as Orthogonal Frequency Division Multiplexed (OFDM) symbols, each frame including a preamble including multiple bootstrap symbols, one or more of the bootstrap symbols carrying signalling data represented as a relative cyclic shift of a signature sequence which has been combined with the one or more of the bootstrap symbols. A bootstrap processor detects the signalling data from the bootstrap symbols using an estimate of the channel transfer function determined from one or more of the bootstrap symbols, and a demodulator circuit recovers the payload data from the payload symbols using the signalling data. The bootstrap processor comprises a channel shaper, which convolves a time domain copy of the signature sequence with the estimate of the channel impulse response to generate a channel shaped signature sequence 1538, a cross-correlator and a cyclic shift detector 1524. The convolving step may be performed by an equivalent step in the frequency domain of multiplying 1530 the estimated channel transfer function and the signature sequence 1536. A cross-correlator is configured to cross-correlate the useful part of each of the one or more bootstrap symbols with the channel shaped signature sequence, and the cyclic shift detector is configured to estimate the signalling data conveyed by each of the one or more bootstrap symbols by detecting a cyclic shift of the signature sequence present in each of the one or more bootstrap symbols from cross-correlation peaks.

IPC: G06F9/38
Filed: 2016-06-16
Abstract: An instruction bundle may be fetched from a first memory (e.g. instruction cache) or a second memory (e.g. instruction scratchpad RAM). A fetch from the second memory takes a predetermined fixed plurality of processor cycles.

Fetching the instructions in advance avoids the need to stall the instruction fetch unit while waiting for instructions to be fetched from the slower second memory. The instructions may be associated with threads, and the threads may be assigned to a first mode or second mode depending on whether the associated instructions are available in the first memory or second memory.

Title: A quantum communication system
Inventor: JAMES DYNES
IPC: H04B10/70
Filed: 2014-06-23
Abstract: This application concerns a quantum communication system comprising a transmitter 1 which is connected to a receiver 17 by an optical fibre 16. The transmitter and the receiver each include an interferometer, each comprising first and second paths, and a phase modulator in the first or second path. The transmitter transmits pulses in pulse pairs 13, 14, which have mutually orthogonal polarization. When the optical fiber exhibits polarization mode dispersion (PMD) this can cause an additional time difference, δt, to emerge between the orthogonally polarized pulses, which degrades desired interference in a receiver. At least one of the interferometers includes a variable delay line 60 to eliminate δt. The variable delay line is controlled by a controller which receives an input (e.g. QBER) indicating the degree of interference of light pulses. The variable delay line permits coarse control and a fibre stretcher 28 provides fine control. The variable delay line may take the form of an electronic delay line 60. An attenuator (70, Fig. 6) may be provided in one arm of one of the interferometers.

Abstract: A generated power control system and control method for an intelligent micro-grid with medium energy storage. The control system mainly comprises a wind-solar hybrid power generation system, a solar thermal power generation set with medium energy storage, and a micro-grid power control system. The control method comprises: a micro-grid centralized control center receives in real time a power instruction transmitted from a micro-grid dispatching automation system, and collects in real time the generated power of the wind-solar hybrid power generation system; an energy management system calculates an optimal power distribution scheme of a micro-grid.

By means of the control method, the technical defects, such as uncontrollability, discontinuity, and large fluctuation of wind energy and solar generated power that are caused by the change in an external environment, can be overcome, the generated power of the micro-grid is stabilized, electric energy of a new energy can be consumed to the greatest extent, and the problems of "wind curtailment" and "light curtailment" in the new energy can be effectively solved.

Title: Current sensor for biomedical measurements
Inventor: JUANPING YUAN
IPC: G01R19/00
Filed: 2017-12-22
Abstract: A current sensor for biomedical measurements comprises switched capacitors 103 & 105, in series across amplifier 101, and switched capacitor network 120 between amplifiers 101, 111. Switches 107 & 109 may be controlled by complementary clocks (A, B: 211, fig. 2), e.g. switch 107 being closed while switch 109 is open so capacitor 103 is reset while 105 charges. The clock signal occurs when charging current passes a threshold determined by comparators (201 & 203, fig. 2). When input current is small and higher frequency amplifier output 111, being linearly related to input current in dependence on the capacitances involved, provides a low noise current measurement. For relatively larger current, flip-flop outputs (207 & 209, fig. 2) provide a frequency output proportional to input current. The dynamic range is therefore widened. Since no external reset or sample clock is required, bandwidth is not limited by sample rate.

Title: I/0-Abstracted field device configurations
Inventor: LARRY O JUNDT
IPC: G05B19/418
Filed: 2016-10-12
Abstract: An I/O-abstracted configuration is defined for a field device that has not yet been assigned or allocated to communicate via a particular I/O device, and the field device (and optionally portions of the process control loop of which the field device is a part) is commissioned based on contents of its I/O-abstracted configuration. The field device's I/O-abstracted configuration is stored in an instance of a device placeholder object, which may be common to multiple types of devices and multiple types of I/O. A property of the device placeholder object may be exposed based on the value entered for another property, and the device placeholder object may store abstracted values as well as explicit or discrete values that are descriptive of the field device and its behavior. Upon I/O-assignment or allocation, values held in the device's I/O-abstracted configuration may be transferred to or otherwise synchronized with the device's as-built configuration.
