Title: Method for data recovery on a data carrier with overlapping data tracks and device thereof
Inventor: PANTEL LOTHAR
IPC: G11B20/18
Filed: 2015-03-02
Abstract: A method of data recovery on an overlapping track storage medium which has a write width at least twice the read width 5, wherein if a defective section 22 of a track is detected, track management data and/or similarity comparison is used to determine if a nearby track holds equivalent data to the defective section due to the width of the write element, if so at least part of the data from said nearby track is used complementarily or as a substitute for the defective section. The neighbouring track may be a guard track 14 of the storage medium. The storage medium may be a shingled magnetic recording medium. The storage medium may be broken into bands 21 wherein the overlap direction switches part way through the band. The guard track may be relocated such that it is situated in the same location as the defective section. If comparison between the two tracks is used then the similarity of the tracks may be compared to a threshold to determine if the neighbouring track should be taken as holding the same data.

The heat spreader may further include alignment tabs 30 and may have low surface roughness in the area of gold plating.
Patent GB-2544489-A (GB)
Title: Branch prediction in a data processing apparatus
Inventor: Alexander Alfred Hornung
IPC: G06F9/38
Filed: 2015-11-17
Abstract: Disclosed is an apparatus with instruction fetch circuitry 10 and branch target storage 14 to store entries of source and target addresses for branch instructions 18. Stored with each entry is a confidence value. When a current address matches a source address in an entry, and the confidence value exceeds a confidence threshold 20, then instruction fetch circuitry retrieves a predicted next instruction from the target address in the entry. The apparatus also has branch confidence update circuitry 16 that increases the confidence value of the entry on receipt of a confirmation of the target address and decreases the confidence value on receipt of a non-confirmation of the target address. When the confidence value meets a confidence lock threshold 22 below the confidence threshold and non-confirmation of the target address is received, a locking mechanism with respect to the entry is triggered. The locking mechanism may mark the entry as locked, cease updating the confidence value of the locked entry and prevent issuance of the signal to fetch the predicted instruction.

Title: Allocation of tiles to processing engines in a graphics processing system
Inventor: JONATHAN REDSHAW
IPC: G06T15/00
Filed: 2015-12-21
Abstract: Primitive fragments are processed in a graphics processing system using a rendering space sub-divided into tiles. Texturing and/or shading is applied to the fragments by processing engines (216) in the system. A cache (218) (e.g. a multi-level cache) in the system stores graphics data for the fragments, the cache including multiple cache subsystems (220). Each subsystem is coupled to a respective set of one or more processing engines. A tile allocation unit (224) in the system operates in one or more allocation modes to allocate tiles to the processing engines. The allocation mode(s) include a spatial allocation mode in which groups of spatially adjacent tiles (e.g. 2x2 groups) are allocated to the processing engines according to a spatial allocation scheme, which ensures that each group of spatially adjacent tiles is allocated to a set of processing engines coupled to the same cache subsystem. Fragments in spatially adjacent tiles thereby get sent to processing engines coupled to the same cache subsystem, improving cache efficiency. One or more of the allocation modes may include a load balancing allocation mode in which tiles are allocated to engines based on computational loads of the engines.

Title: Discharge port of a screw compressor
Inventor: SCOTT MICHAEL BRANCH
IPC: F04C29/12
Filed: 2014-10-10
Abstract: An improved discharge port of a rotary screw compressor is described. A discharge port of a screw compressor generally includes a restrictive portion to help prevent a leakage of working fluid back to a suction side of the compressor. The improved discharge port is configured to have a restrictive portion with a reduced size compared to a restrictive portion of a conventional discharge port, resulting in an enlarged opening of the discharge port compared to a conventional discharge port. The improved discharge port can help discharge the compressed working fluid more quickly than a conventional discharge port, reducing and/or avoiding over-compression of the working fluid. The efficiency gained due to the enlargement of the opening may be more than the efficiency loss due to leakage of working fluid back to the suction side, resulting in a net efficiency gain of the compressor.

Title: Synchronisation of audio and video playback
Inventor: ROSS BURRIDGE
IPC: H04N21/43
Filed: 2014-05-08
Abstract: Playback of audio content is synchronised with displayed video content based on at least one ultrasonic synchronisation signal received during display of the video content. The ultrasonic synchronisation signal encodes a time code through modulation of one or more ultrasonic carrier signals 410-1 to 410-8, where a first ultrasonic carrier signal which has been amplitude modulated to encode a logical "1" or a logical "0" in each of a plurality of data-carrying segments 412. Each of the data carrying segments is followed by a non-data-carrying segment 414, in which the amplitude of the first ultrasonic carrier signal does not exceed a predetermined threshold. A playback point in the stored audio content is then determined based on the determined timecode, and the stored audio content is played to the viewer from the determined playback point such that the audio content is played in synchronisation with the displayed video content.

Title: Enhancing engine performance to improve fuel consumption based on atmospheric ice particles
Inventor: Nicholas Race Visser
IPC: G01S13/95
Filed: 2016-10-21
Abstract: Systems and methods for controlling an aircraft engine based on solid ice water content 512 (e.g. ice crystals from cirrus clouds). The method includes identifying (306, figure 3) by processor(s) one or more points (420, figure 4) along an aircraft flight path (410), receiving (308, figure 3) reflectivity measurements 502 for each point (420, figure 4) obtained using an onboard device (e.g. radar 112 or lidar, figure 1), determining (310) ice water content estimate 512 for each point (420) based at least in part on reflectivity measurements 502, and controlling (312) at least one component of the aircraft engine (e.g. variable bleed valve) based at least in part on ice water content estimate 512 for at least one point (420). The system and method may result in fuel economy and savings and may particularly be used during icing conditions since large amounts of ingested ice water can require more energy for conversion to vapour during combustion. Reflectivity measurements 502 may in part be obtained from other aircraft or based on weather data. Ambient temperature measurements 504 may be obtained using a temperature sensor (116, figure 1). Water content detection mode can be activated based on ambient temperature threshold.

Filed: 2014-12-19
Abstract: An electronic apparatus comprising certification means to certify a mounted battery, and control means such that, if a first processing is started before certification processing by the certification means is completed, the first processing is stopped S715 if the certification processing by the certification means is subsequently completed S709 and the certification is not successful S710, and if a second processing is started before the certification processing by the certification means is completed, the second processing is continued if the certification processing by the certification means is completed after the start of the second processing, and the certification is not successful (showing the battery is counterfeit or not genuine). Preferably, first and second processes continue if the battery is deemed to be authentic.
