Patent GB-2481747-A (GB)
Title: Open hole frac system
Inventor: RICHARD BENNETT M
IPC: E21B33/10
Filed: 2010-03-26
Abstract: A fracturing operation is done in open hole without annular space isolation. The annular space is spanned by telescoping members that are located behind isolation valves. A given bank of telescoping members can be uncovered and the telescoping members extended to span the annular space and engage the formation in a sealing manner. Pressurized fracturing fluid can be pumped through the telescoped passages and the portion of the desired formation fractured. In a proper formation, cementing is not needed to maintain wellbore integrity. The telescoping members can optionally have screens. Normally, the nature of the formation is such that gravel packing is also not required. A production string can be inserted into the string with the telescoping devices and the formation portions of interest can be produced through the selectively exposed telescoping members.

Title: Operating a motor having the stator flux aligned with the rotor flux
Inventor: LYNN DAVID MARK
IPC: G01R31/34
Filed: 2012-01-12
Abstract: An electrical drive system 10 includes an electric motor 70 comprising an armature, which is mounted on a stator, and a rotor. The stator flux is aligned with the rotor flux to enable current to flow in the armature without inducing torque on the rotor shaft 80. The method may be used, for example, in testing the electrical drive system. The electric drive system can carry full rated current yet produce little or no torque, thereby increasing the current that can be tested during electrical drive test procedures, compared with prior-art procedures. The method may be used in heating the electric motor for example for the purpose of de-icing as it enable the electric drive system to carry full rated current yet produce little or no torque, thereby allowing the current to be used to generate heat in the motor.

Inventor: WORONOWICZ KONRAD
IPC: B60L5/00
Filed: 2012-04-23
Abstract: A land vehicle such as a rail vehicle or a road automobile is provided with electric energy by producing an electromagnetic field on a primary side located on the track, or at a stop, of the vehicle and receiving the electromagnetic field on a secondary side onboard the vehicle above the source of the electromagnetic field by magnetic induction. A primary side conductor assembly 11 carries an alternating current to produce the electromagnetic field and a magnetisable shield assembly 23 extends sideways of, and on the same level, as the conductor 11 to shield regions that are beyond the shield from the electromagnetic field. Similarly a secondary side conductor (fig 6, 21) may have a magnetizable side shield (fig 6, 23) to shield regions beyond the shield from an electromagnetic stray field produced while the conductor is carrying current. The shield may extend from sideways of the conductor and to a level above its lateral edge to shield areas at a higher level from the electromagnetic field. The magnetisable shield may be a U-shape and extend around three sides of the lateral edge of the conductor and redirect flux F around the edge of the conductor 21.

Title: Data processing apparatus and method
Inventor: ATUNGSIRI SAMUEL ASANGBENG
IPC: H04B1/707
Filed: 2013-02-11
Abstract: The invention discloses a spread spectrum communication system for framed data. It may be used to improve satellite broadcasting, e.g. DVB-S2 broadcasts. Payload data 222 of a frame is passed through a modulator to map the data onto modulation symbols. The output from this modulator is spread using a selected first spreading code S1 selected from a plurality of first spreading codes which have mutually different spreading factors. This allows payload data to be transmitted with a variable spreading factor. A header of the frame contains 231 physical layer signaling data (PLS) and an indication of the selected first spreading code. At least a portion of this header is spread using a second spreading code S2. The spreading factor of the second spreading code is greater than or equal to the spreading factor of each of the first spreading codes. This ensures that the header can always be received, even when the SNR is poor. The header may additionally include a start of frame (SOF) indication 203, spread using a third spreading code S3. The frame is modulated onto an RF carrier for transmission. There are transmitter and receiver embodiments.

Title: Auxiliary power tool handle
Inventor: GRIFFIN PAUL W
IPC: B25G1/00
Filed: 2012-07-25
Abstract: A handle for controlling a power tool by configuring the handle in either a straight or T- shaped position. In the straight position, the handle design serves as a rotational safety control that allows a user to control the rotational reaction of the tool by placing the user's hand in a position that is perpendicular to the main body of the tool. In the T-shaped configuration, the user can apply rotational force and longitudinal force more easily because the hand position is tangent to the tool base. A fastener couples a base of the handle to a band that grips the power tool and facilitates the user control.

Title: A data processing apparatus and method for performing a transform between spatial and frequency domains when processing video data
Inventor: SYMES DOMINIC HUGO
IPC: H04N19/625
Filed: 2013-05-07
Abstract: A data processing apparatus for performing transforms between spatial and frequency domains when processing video data comprises transform circuitry to receive N input values (i.e. relating to video data or transformed video data) and, for each input value, generating a set of M internal input values. The M internal input values are supplied to base circuitry 215 which performs an operation equivalent multiplying a matrix of the M internal input values by a matrix of coefficients (e.g. supplied from coefficient generation circuitry 220). The matrix of coefficients may be a Hankel matrix which is a square matrix with constant skew diagonals, where each element of the array identifies a coefficient. The matrix multiplication returns a set of M internal output values which are provided to the transform circuitry. At the transform circuitry, each set of M internal output values is used to derive an output value (i.e. relating to transformed video data or video data), corresponding to the original input value. The process is repeated to produce N output values, corresponding to the N input values. A method for performing transforms between spatial and frequency domains when processing video data is also claimed. The apparatus and method described can be used during encoding of video data to transform the data from the spatial to the frequency domain, or during decoding of video data to perform an inverse transform the data from the frequency to the spatial domain. The transforms performed may be a Discrete Cosine Transform (DCT) and Inverse Discrete Cosine Transform (IDCT) respectively. The conversion between N input values and M internal input values are performed using permutation circuitry 200 and adding/summation circuitry 210, with corresponding circuitry 225,240 to derive N output values from the M internal output values. The apparatus and method described are intended to enable more efficient processing of larger transform units (e.g. 32x32 blocks of pixel data) when encoding/decoding video data in accordance with the High Efficiency Coding (HEVC) standard.

Title: Server-rendering of graphics for remote client
Inventor: PJAK DAWID STANISLAW
IPC: G06F9/50
Filed: 2013-07-19
Abstract: A method for transmitting rendered 3d images to a remote client device 550 comprises rendering 720 server rendering elements to generate reference image data 580 and rendering 722 client rendering elements to generate a client auxiliary image data 582. Either the reference image and the client auxiliary image, or the reference image and auxiliary data are compressed 730 to generate compressed client data which is transmitted 740 over a network 570 to the client device 550. Whether the reference image is compressed with the client auxiliary image or the auxiliary data is dependent upon the relative amount of data representing the client auxiliary image and auxiliary data. A server system with a rendering subsystem to perform the method is also claimed. The method allows auxiliary rendering information to be separated from rendering information used to describe the reference image. The client device may alter the auxiliary data and generate a new image based upon the reference image and rendered scene information from the auxiliary data without creating additional network bandwidth or server workload.
