Title: Handling of non-correct block vectors generated for intra block copy coding mode
Inventor: CHRISTOPHE GISQUET
IPC: H04N19/90
Filed: 2015-06-08
Abstract: Decoding a block of pixels in a current image using an Intra Block Copy mode in which the current block is predicted from a predictor block in the current image as indicated by a vector associated to the current block. The decoding comprises generating a list of vector predictor candidates; obtaining an index from the bitstream indicating a vector predictor from the list; obtaining a vector from the vector predictor; determining whether or not the obtained vector meets a predetermined criterion 1223; and, obtaining a predictor block in the current image using either the obtained vector or another interpreted vector, depending on the determination step. Preferably the predetermined criterion is that the obtained vector is null, defines an area outside the causal area or the current image, or defined an area that is Inter predicted from another image. Preferably, if the predetermined criterion is met, the vector is modified in a way which may include subtracting the block size from the first component of the vector or setting the first component to some fixed real negative multiplier of the block size. In embodiments the candidate lists are the conventional AMVP 1202 or Merge 1201 candidate list. A corresponding encoding claim is included.

Title: Systems and methods for monitoring temperature using a magnetostrictive probe
Inventor: KE WANG
IPC: G01K11/22
Filed: 2014-11-17
Abstract: Systems and methods for monitoring temperature distribution in downhole equipment using magnetostrictive probes. In one embodiment, an ESP motor has a stator with a rotor and shaft rotatably positioned within the stator. Magnetostrictive sensors are positioned within the motor. Each magnetostrictive sensor has a transducer, a probe, and electronic circuitry coupled to the transducer. The circuitry generates an initial electrical signal that is conveyed to the transducer. The signal passes through one or more coils in the transducer, generating magnetic fields that induce an acoustic signal in the probe. The acoustic signal propagates through the probe and waves are reflected from reflection points in the probe. The transducer senses the reflected acoustic waves and provides corresponding electrical signals to the circuitry, which determines timing intervals associated with the reflected waves and uses this information to determine temperatures at one or more locations in the probe (hence in the monitored equipment).

Title: Methods and apparatus for detecting and preventing compressor surge
Inventor: MARCOS PELUSO
IPC: F04D27/02
Filed: 2017-03-22
Abstract: Apparatus for controlling a valve coupled to a compressor, comprising a transmitter and a controller. The transmitter determines a derivative process value 302 of the compressor, preferably from first and second pressure values, and transmits the value to the controller, which is separate from the transmitter. The controller compare the derivative process value to a threshold value 304, which preferably indicates the initiation of a surge event in the compressor. If the derivative process value fails to satisfy the threshold value 306, then the controller actuates a valve 312, so that an additional derivative process value 314 of the compressor determined by the transmitter satisfies the threshold. Also claimed is a corresponding method and a set of instructions in a machine-readable storage medium. Preferably, there are means to determine the reliability of the derivative process value 308. This involves obtaining derivative process values from at least three transmitters (402, fig 4) and comparing them (404), so that the functionality of sensors corresponding to the transmitters can be determined (408).

Title: Advanced V2X event dissemination
Inventor: PRAMITA MITRA
IPC: H04W84/18
Filed: 2018-02-01
Abstract: A host vehicle 200 (i.e. a car) packages sensed data into a first unit. It is determined whether a vehicle-to-infrastructure (V2I) connection is active or inactive. If the V2I connection is active a TRUE flag is appended to the unit. If the V2I connection is inactive a FALSE flag is appended to the unit. The first appended unit is transmitted over a vehicle-to-vehicle connection (V2V). The host vehicle may receive a second appended unit over a V2V connection. The second appended unit contains a TRUE or FALSE flag. If a FALSE flag is present the host vehicle transmits the second appended unit over the V2I connection. If a TRUE flag is present the host vehicle does not transmit the second appended unit over the V2I connection. The host vehicle may have a virtual map 200x. Comparison of a time stamp of the received second appended unit may be used in order to determine whether to update the host vehicles virtual map with data provided in the second appended unit. The invention provides ways of periodically synchronising maps between vehicles and base servers 300x.

Difference in tile shape and size between projection plane and image space creates distortion. Transformations may be applied to vertex coordinates. Distortions may differ in vertical and horizontal directions. Distortions may be applied using a single rendering pass.
