Title: System and method for the detection and transmission of downhole fluid status
Inventor: LI GAO
IPC: E21B34/06
Filed: 2016-03-09
Abstract: Systems and methods for signaling the detection of a fluid change in a wellbore can be used during wellbore operations, such as cementing a casing in the wellbore. The systems and methods involve using burst discs to provide a pressure pulse that can be detected uphole and there by provide a signal related to when a fluid change has reached a predetermined position in the wellbore. The burst discs can be activated to prevent fluid flow in a portion of the wellbore by a sensor that detects a property that is different between two fluids. Once activated, the pressure of the fluid on the burst discs subsequently ruptures the burst disc and creates the pressure pulse.

Title: Performing kernel striding in hardware
Inventor: WILLIAM JOHN GULLAND
IPC: G06N3/063
Filed: 2017-09-22
Abstract: Convolutional neural network (CNN) processing system 100 comprises: special‑purpose hardware circuit 110 including matrix and vector units 120, 140; and neural network implementation engine 150. The engine processes an input tensor of a CNN with stride greater than one, by: using an equivalent convolutional layer having stride one to generate a first tensor by convolving the input tensor and a kernel; generating a second tensor via element-wise multiplication and masking tensors to zero out additional elements of the first tensor which would not have been generated by the first layer; max pooling the second tensor to remove the zeroed out additional elements. Matrix unit 120 is a systolic array. The Hardware circuit stores input tensors and kernels in unified buffers and dynamic memories, respectively. Advantages comprise performing larger stride convolutions on an incompatible special-purpose circuit avoiding off-chip computations. Apparatuses can be field‑programmable-gate-arrays (FPGA) or application-specific-integrated-circuits (ASIC).

Title: Content delivery
Inventor: RORY TURNBULL
IPC: H04N21/6408
Filed: 2020-06-12
Abstract: A method of managing a network for delivering content to a client device 304, where content segments are delivered to a proxy 308 in a multicast group, before delivery from the proxy to the client device over unicast. The proxy intermittently leaves the multicast group to probe the network by making unicast request for content segments, receiving those segments over unicast from the content server and forwarding those segments onto the client device. This allows the client device to determine the maximum throughput between the content server and the client device via the proxy, and thus the client device can use its adaptive bit rate algorithms to determine if the network can support a switch to a higher bit rate stream, and request a higher bit rate stream accordingly. The higher bit rate stream can be serviced by the proxy joining or establishing a suitable multicast group.
