Title: Check pointing a shift register
Inventor: PHILIP DAY
IPC: G11C19/28
Filed: 2015-07-08
Abstract: Method and hardware structures for check pointing a main shift register (102 figure 1) one or more times. The main shift register may be a Global History Register (GHR), storing information on the status of predicted microprocessor conditional branches (jumps). The hardware structure includes a circular buffer 1502 used to store the data elements most recently shifted onto the main shift register (GHR) which has an extra data position for each check point and an extra data position for each restorable point in time; a pointer 1560 that identifies a subset of the data positions of the circular buffer as active data positions; an update history shift register 1504 which has a data position for each check point (2202,2204,2206) which is used to store information indicating whether the circular (ring) buffer was updated in the same clock cycle as a particular check point trigger event; and a check point generation logic (1404, figure 2) that derives each check point by selecting a subset of the data elements stored in the circular buffer based on the information stored in the update history shift register 1504. The check point trigger may be an instruction sent to an execution unit for execution. Check point generation logic can therefore derive appropriate check points based on the information stored in the update history register and the history stored in the extended shift register. The hardware structure may comprise logic configured to determine in each clock cycle whether a check point trigger event has occurred, and if so, determine if the circular buffer is in the current cycle: and if this is the case, shift information (1) onto the update history shift register indicating shift register has been updated (see figures 8 or 12). If there is no update of the circular buffer alternate information (0) is shifted onto the update history shift register. A computer program defining a processor comprising the hardware structure is also included.

Title: Sensing methods for wireless communication devices
Inventor: ROY RON
IPC: H04W74/08
Filed: 2016-09-29
Abstract: Selecting a set of subframes for monitoring in a wireless communication is performed using a variety of methods. In one aspect the subframe selection is based on a cost metric. The cost metric takes into account: a probability of missing detection of a transmission with periodicity p from another mobile device; an average number of transmissions with periodicity p that are expected from another mobile device within a predefined transmission period of the mobile device; and a number of transmission cycles of the mobile device that need to occur in order to have a single potential collision with each periodic transmission from said at least one other wireless communication. Further aspects provide selecting subframes contained within a selected number of fixed duration time windows (for instance 100ms). The invention provides a trade-off between avoiding future collisions and battery life.

Patent GB-2563055-A (GB)
Title: Ice protection system
Inventor: Ian Stophers
IPC: B64F5/30
Filed: 2017-06-01
Abstract: The ice protection system has an actuator 10 coupled to a structure 30, such as an aircraft. A controller 20 connected to the actuator generates a drive signal (fig.1) to cause vibrations in the structure. The drive signal is a frequency chirp or sweep over a period of time, controlled so the vibrations propagate through the structure coinciding at an area 40 remote from the actuator (i.e. slower traveling low frequency vibrations are generated before faster traveling high frequencies), to remove ice and/or other accretions such as dust, dirt or other detritus. The controller may generate the drive signal as a sequence of pulses switching between fixed positive and negative values, shortening the width of the pulses between zero-crossing positions. Pulse widths of pulses at or adjacent resonant frequencies of the actuator may be shortened. The controller may be connected to a number of actuators, each driven with its own drive signal. The controller may generate the drive signals based upon processed vibration data received from sensors (fig.4,50) recorded during a calibration pulse. The processing of the vibration data may include time reversal, extrapolation and/or interpolation. A switched amplifier may be used between the controller and the actuator.
