Title: Flash memory management
Inventor: MADHUSUDANAN KANDASAMY
IPC: G06F12/06
Filed: 2016-10-12
Abstract: The application aims to combine the advantages of using flash memory as a new tier of memory between DRAM and a magnetic spinning disk, and the load-store model of flash memory, without incurring the drawbacks of either method. It works by providing direct access to flash memory through a physical address space. The method 300 begins by first establishing a physical memory address, which includes a flash memory portion 310. It then detects, with respect to the physical memory address space, an access request 330. Finally, it then accesses, using a load-store technique, the flash memory portion of the physical address space 370. The load portion of the load-store technique works by copying a set of target data from the flash memory into a register, the store portion works by copying the target data from the register into the flash memory. The CPUs can also access the flash memory directly via a field-programmable gate array adapter.

Suitably, no additional current blocking switches are required between motor 230 and inverter 220. The switches may conduct in the off-state when reverse biased, and a negative gate source voltage applied to control the reverse conduction threshold voltage.

IPC: G06F21/51
Filed: 2017-01-20
Abstract: Disclosed is a method of evaluating installer packages to deny or allow the payload to be installed in a host computer. A first reputation of an installer is determined 604 based on contextual information including its source (e.g., its publisher), a cryptographic signature or certificate, the process or user that carried out its download, or if the installer has been vetted by a security policy, etc. Each of the computer objects is then be unpacked 606 for individual analysis 610 (e.g., a static analysis) regarding each object's compliance with a security policy, thereby producing a second reputation for each computer object. A decision 618 is then made whether to allow or deny the execution of the installer/objects, e.g., during an installation process, by reconciling 616 the first reputation of the installer and the second reputation for each computer object.

Inventor: Nick Tuson
IPC: G06T19/00
Filed: 2017-01-25
Abstract: A method of navigating viewable content within a virtual environment generated by a virtual reality system is disclosed. The virtual reality system comprises a display 13 for displaying the virtual environment comprising viewable content in a virtual reference frame to a user, and at least one head mountable sensor 14 such as an accelerometer or gyroscope for sensing a tilt of the user's head in a real reference frame. The method comprises the steps of moving the virtual reference frame relative to the real reference frame in response to the tilt of the user's head to present the viewable. Preferably, the rate or speed of movement of the virtual reference frame is governed by the tilt orientation and/or length of time the head is held in a tilt position. A control module 15 may present alternative interactions with the virtual reality system 10 by presenting two navigational modes, an input mode such as lists, menu options and a viewing mode presenting a portion or scene within the virtual environment both navigated using head tilts or head gestures.

Title: Fault detection based on brake torque and temperature
Inventor: ANDREW BILL
IPC: B64F5/60
Filed: 2017-01-26
Abstract: The fault detection system has a controller which, for at least one break during a braking event, receives information on the braking demand requested, the amount of torque reacted by the brake, wear condition of the brake, wheel speed of a wheel associated with the brake, and maximum brake temperature during the event; the controller calculates an expected maximum temperature based on the torque, wear and wheels speed information and determines whether there is a discrepancy between the expected temperature and the measured temperature, and between the braking demand and the measured torque; the controller generates one of three different alerts if there is a discrepancy in the temperature, torque or both. A temperature discrepancy may indicate faults relating to brake components such as a ruptured brake disc or hydraulic failure; a torque discrepancy may indicate faults relating to failure or incorrect operation of sensors, a discrepancy in both temperature and torque may indicate faults relating to a torque sensor. The controller may utilise predefined temperature discrepancy thresholds, from brake calibration data, and compare measured values from several consecutive flight cycles in its determination. A claim for an aircraft with sensors and the controller, and a method for detecting and diagnosing faults with an aircraft braking system are included.

Filed: 2016-10-11
Abstract: A radio frequency identification (RFID) tag reading system and method accurately and rapidly determine, in real-time, true bearings of RFID tags associated with items in a controlled area. Primary transmit and receive beams are steered over the area, and multiple secondary receive beams are substantially simultaneously steered to a plurality of bearings in the area. The highest signal strength of secondary receive signals from the secondary receive beams determines an approximate tag bearing of each tag. Two secondary receive beams at opposite sides of the approximate tag bearing in elevation are selected to obtain a pair of elevation offset signals, and two secondary receive beams at opposite sides of the approximate tag bearing in azimuth are selected to obtain a pair of azimuth offset signals. The elevation offset signals and the azimuth offset signals are processed to determine a true bearing for each tag in real-time.

Title: Modulators
Inventor: JOHN PAUL LESSO
IPC: H03M7/30
Filed: 2018-08-24
Abstract: A time-encoding modulator 100, such as delta-sigma modulator, receives an input signal Sin and provides at its output a time encoded signal Spwm. A comparator 101 is located within the forward signal path of a feedback loop of the TEM. Also in the loop are a filter 104 and a controllable delay element 106. A latching element (302, fig.3; 402 fig.4) may be located within the forward path to synchronise signal transitions to a clock signal CLK1. The delay element may be a digital delay line (401, fig.4a) or a counter-based delay (fig.4b), and is synchronised to the clock signal. The delay may be controllable as an integer number of clock periods. The introduction of a controlled delay allows the cycle period of the TEM to be controlled (CPC 506, fig.5). Dither may be applied. It is disclosed that cycle period control may also be effected by controlling the hysteresis of the comparator in the TEM (fig.11). It is stated that use of both hysteresis control and controlled delay in the loop of a TEM may allow desired cycle period characteristics, e.g. limit cycle frequency, to be achieved whilst potentially easing the requirements for the comparator and/or delay element.
