Abstract: Hardware implementations of, and methods for processing, a convolution layer of a DNN that comprise a plurality of convolution engines wherein the input data and weights are provided to the convolution engines in an order that allows input data and weights read from memory to be used in at least two filter-window calculations performed either by the same convolution engine in successive cycles or by different convolution engines in the same cycle. For example, in some hardware implementations of a convolution layer the convolution engines are configured to process the same weights but different input data each cycle, but the input data for each convolution engine remains the same for at least two cycles so that the convolution engines use the same input data in at least two consecutive cycles.

Abstract: Hardware implementations of DNNs and related methods with a variable output data format. Specifically, in the hardware implementations and methods described herein the hardware implementation is configured to perform one or more hardware passes to implement a DNN wherein during each hardware pass the hardware implementation receives input data for a particular layer, processes that input data in accordance with the particular layer (and optionally one or more subsequent layers), and outputs the processed data in a desired format based on the layer, or layers, that are processed in the particular hardware pass. In particular, when a hardware implementation receives input data to be processed, the hardware implementation also receives information indicating the desired format for the output data of the hardware pass and the hardware implementation is configured to, prior to outputting the processed data convert the output data to the desired format.

Abstract: A downhole closed loop method for controlling a curvature of a subterranean wellbore while drilling includes controlling a direction of drilling such that the drilling attitude is substantially equal to a setpoint attitude. A setpoint rate of penetration is processed in combination with a setpoint dogleg severity to compute a setpoint attitude increment. The setpoint attitude may be adjusted by the setpoint attitude increment. The setpoint attitude may be incremented at some interval to control the curvature of the wellbore while drilling.

Abstract: We describe circuits and methods for compensating for gate kickback in electro-optic displays, in particular electrophoretic displays. In embodiments the method comprises compensating gate kickback comprising a change in voltage between a pixel electrode and a common electrode of the display arising from capacitive coupling between a gate drive line and the pixel electrode by offsetting a value of a common voltage on the common electrode by an offset value dependent on a difference between a magnitude of said positive gate voltage and a magnitude of said negative gate voltage.

Abstract: An apparatus for automatically detecting the presence of a reagent strip (14) having a body fluid sample disposed thereon and for inspecting the reagent strip (14) after the presence of the reagent strip (14) is detected is provided with a detection system adapted to automatically detect the presence of a reagent strip (14) at a reagent strip receiving area (12), a light source (64 or 68) adapted to illuminate the reagent strip (14) after the presence of the reagent strip (14) at the reagent strip receiving area (12) is detected, and a detector (66 or 70) adapted to receive light from the reagent strip (14) when the reagent strip (14) is being illuminated by the light source.

Abstract: A screw rotor machine for compressing air or other working fluid comprises a housing including two intersecting bores axes which together define a working space. The pair of intermeshing rotors are rotatably mounted one in each bore. The rotors have helical lands and intervening grooves whereby rotation of the rotors in connecting engagement is effective to compress the working fluid (or to expand the fluid if the machine is used as an expander). A low pressure port and a high pressure port formed in the housing at opposite ends thereof permits inlet and outlet of the working fluid. The grooves of the rotors each have a primary flank and a secondary flank. The tips of the primary flanks of both the male and female rotors are formed by parabolic arcs which generate major portions of one of the flanks of the opposite rotors. A major portion of the secondary flank of the female rotor is also a parabolic arc.
