Title: CMOS GOA circuit for reducing load of clock signal
Inventor: SHIJUAN YI
IPC: G09G3/36
Filed: 2016-05-25
Abstract: A CMOS GOA circuit for reducing the load of a clock signal, being provided with an input control module (1), a latch module (2), a reset module (3), a signal processing module (4) and an output buffer module (5). In the input control module (1), a clock signal (CK(M)) only needs to control second and fifth N-type thin film transistors (T2, T5) to be driven, so that the number of thin film transistors driven by the clock signal can be reduced, the load of the clock signal can be reduced, and the resistance capacitance delay and power consumption of the clock signal can be reduced. The latch module (2) uses the reverse-phase scanning driving signal (XGate(N-2)) of theN-2nd-stage GOA unit as an input control signal of a stage transmission signal (Q(N)), so as to solve the competition issue appearing when the stage transmission signal (Q(N)) is inputted, and uses the scanning driving signal (Gate(N+2)) or reverse-phase scanning driving signal (XGate(N+2)) of the N+2nd-stage GOA unit as a pull-down control signal of the stage transmission signal (Q(N)), so as to solve the competition issue appearing when the stage transmission signal (Q(N)) is pulled down.

Title: Entropy and value based packet truncation
Inventor: STEPHEN FRANK DONNELLY
IPC: H03M7/30
Filed: 2018-10-16
Abstract: Network packets may be captured by a network recorder or probe and stored in a storage device to create a history of packets. There is a need to store the captured data efficiently to preserve storage space. The invention analyses the captured packets to determine if they can be reduced in size before storing. Packets in a computer network are received via an input port and the header fields and starting point of the payload are identified. The entropy of the payload is estimated and compared to a threshold. A signal (e.g. entropy exceed signal) is generated indicating if a payload may be truncated or compressed. The value of a packet may be determined based on the header, and all or some of the data stored in the storage device based on its value and estimated entropy. The user may specify policies or rules for compressing or truncating the packets. The recorded packets may be used for incident investigation (e.g. hacking) or performance evaluation. By being economical with storage one can retain more information for less time or less information for more time. A data centre may be provided where a network recorder comprises daughter cards providing the invention.

Abstract: Methods and apparatus is provided for use in a medical procedure for image acquisition using a high-resolution imaging system, a three dimensional imaging system and a navigation system. A 3D imaging scan of an imaged portion of the surface of the patient is acquired using the three dimensional imaging system. Then, a first high- resolution imaging scan covering a first sub-portion of the imaged portion is acquired using the high-resolution imaging system, which is tracked by the navigation system. The 3D imaging scan and the first high-resolution imaging scan are combined to create an enhanced three dimensional image having contour lines to provide a visual representation of depth derived from depth information acquired from both the three dimensional imaging system and the high-resolution imaging system. Subsequent high resolution scans may then be stitched into the image and the updated image displayed in real-time.

The housing has a pair of apertures (4,5) each affording passage (20) for a corresponding knife inserted blade-first into the cavity. The cabinet has at least one pair of blade guides (4, 5, 26, 28) within the housing that are configured to engage with a knife to guide movement of the blade during insertion and removal of the knife. Within the cavity is at least one pair of carriages (34, 34') moveable along opposite first and second directions (36,36') relatively away from and towards a corresponding aperture. Each carriage carries an abutment (38) for making abutting contact with the corresponding knife shoulder during the guided movement of the blade. The pair of carriages are interlinked (40) whereby, in use, movement of a first carriage (34) in the first direction (36) caused by the abutting contact during insertion of a first one (2) of the knives through a first aperture (4) causes movement of a second carriage (34') in the second direction (36'), such that a second one (3) of the knives previously inserted into a second aperture (5) is moved outwards from the second aperture to assist removal of the second knife from the second aperture.

Title: Graphics processing units and methods for controlling rendering complexity using cost indications for sets of tiles of a rendering space
Inventor: JOHN HOWSON
IPC: G06T15/00
Filed: 2017-01-12
Abstract: A graphics processing unit (GPU) processes graphics data using a rendering space which is sub-divided into a plurality of tiles. The GPU comprises cost indication logic configured to obtain a cost indication for each of a plurality of sets of one or more tiles of the rendering space. The cost indication for a set of tile(s) is suggestive of a cost of processing the set of one or more tiles. The GPU controls a rendering complexity by controlling the number of samples rendered and which primitives are rendered in tiles based on the cost indication for those tiles. This allows tiles to be rendered in a manner that is suitable based on the complexity of the graphics data within the tiles. In turn, this allows the rendering to satisfy constraints such as timing constraints even when the complexity of different tiles may vary significantly within an image.

Title: Skive cut borehole screen end ring
Inventor: Jai K Koll
IPC: E21B43/10
Filed: 2018-07-19
Abstract: A borehole screen such as one with a wire wrap/ slip on screen on a base pipe with variable external dimensions features an end ring assembly that is one piece with a skive cut to allow fitment over a screen jacket that covers the wire wrap. The assembly has a cylindrically shaped component to go over the screen jacket and a radial component at one end oriented toward the base pipe. The assembly can be mounted over the base pipe without sliding the assembly over the end of a base pipe due to the skive cut. Relative sliding along the skive cut gets the desired dimension over the screen jacket to control sand inflow followed by the skive cut being sealed with a weld. The radial component is attached to the base pipe such that two welds complete the end assembly of the screen.
