Title: An interconnect and method of operation of an interconnect
Inventor: PETER ANDREW RIOCREUX
IPC: G06F13/40
Filed: 2015-01-12
Abstract: An interconnect for connecting a plurality of master devices and a plurality of slave devices comprises hazard management circuitry to serialise transactions to overlapping addresses; gating circuitry ensuring ordered write observation (OWO) behaviour at an interface to one or more of the master devices, the gating circuitry receiving write address transfers of write transactions and performing a gating operation to gate onward propagation of the write address transfers to the slave devices in order to ensure the OWO behaviour. The gating circuitry performs the gating operation under control of the hazard management circuitry. The interconnect may further comprise deadlock avoidance circuitry to gate onward propagation of write address transfers of write transactions. The benefit for this interconnect is that, for write transactions that are subjected to hazard checking by the hazard management circuitry, this removes the need to implement any other processes to specifically manage OWO behaviour for those write transactions.

Filed: 2015-09-02
Abstract: Method, computer program implementation and system to encode data to be written to a memory which comprises writing first data 512 to a memory and then reading the same first data 514 and further analysing to determine if an error is present 516, as caused by electron fast de-trapping for example; encoding second data based on the analysis of the first data 518, the encoded data written to a position (or cell) adjacent to the actual error (if found), and writing the encoded second data to the memory at the particular position 520. The memory may be a non volatile memory system (NVM) such as a solid state drive including a three dimensional flash memory comprising a plurality of word lines having single level or multi-level cells. The reading of the memory may be based on a predetermined threshold which may be a read voltage level threshold. The analysing stage may further comprise of a comparison of the first read data to a copy of the first data which is different (not similar) to the first data. Analysis also indentifies the error position of the memory cell such that the position of the second data is adjacent the identified error position, and which could be located at a different word line. The encoding may be performed by a flash memory controller. The second data may be written to memory at the position to cause intentional inter-cell interference (coupling) with the first data.

IPC: H02S50/00
Filed: 2016-02-25
Abstract: A micro-inverter which maximises the power output for an array of solar cells, comprising a logarithmic method of determining the maximum power point (MPP) of a solar panel, a two-phase inverter, an isolation stage controlled using the MPP tracking information, a zero voltage switching device with self-adjusting frequency, and ability to convert DC to AC, to feed to the AC mains supply.

Each display controller (21) also receives position information relating to a change in lateral position and/or stacking order position of one or more bounded regions that are to be displayed at least partly on that display panel (21). If the display controller (24) determines that it does not have knowledge of display data in the bounded region (S2, S3, S4, S5) to be displayed on the display panel for which the position information was received, it obtains that knowledge from another display controller (24) that has such knowledge. The display controller (24) then processes the display data for the portion of the complete image utilizing the knowledge obtained from another display controller (24), and outputs the processed display data for the portion of the complete image to the corresponding display panel (21).

Title: Optical pressure sensor
Inventor: RALF-DIETER PECHSTEDT
IPC: G01L27/00
Filed: 2012-03-16
Abstract: Disclosed is an optical pressure sensor comprising a sensor head 14 including both a pressure sensing optical cavity 22 and a temperature sensing optical cavity 24. An interrogator 20 is optically coupled to the sensor head and arranged to generate a signal representing pressure 30, said signal being temperature corrected. The interrogator comprises first 18 and second 19 optical analysers arranged to detect the responses of the pressure and temperature sensing cavities respectively. The first analyser outputs a signal at a greater rate than the second analyser. The design is intended to alleviate the temperature sensitivity of pressure sensors caused by thermal expansion and changes to material properties at elevated temperatures. The pressure-sensing cavity may be a physical cavity whereas the temperature-sensing cavity may comprise material. The two cavities may be adjacent to one another and may be Fabry-Perot cavities. The response of the second analyser may include a response to pressure, and therefore an iterative procedure may be required to evaluate both properties.
