Abstract: Integrated circuit devices, methods, and circuitry for implementing and using a systolic array are provided. Such circuitry may include processing elements arranged in a triangular systolic array. The processing elements may receive an input matrix and perform Cholesky decomposition in a first stage, triangular matrix inversion in a second stage, and matrix multiplication in a third stage to produce an inverse of the input matrix as an output matrix.

Abstract: Systems and methods are disclosed for enhancing network performance by using modified traffic control (e.g., rate limiting and/or scheduling) techniques to control a rate of packet (e.g., data packet) traffic to a queue scheduled by a Quality of Service (QoS) engine for reading and transmission. In particular, the QoS engine schedules packets using estimated packet sizes before an actual packet size is known by a direct memory access (DMA) engine coupled to the QoS engine. The QoS engine subsequently compensates for discrepancies between the estimated packet sizes and actual packet sizes (e.g., when the DMA engine has received an actual packet size of the scheduled packet). Using these modified traffic control techniques that leverage estimating packet sizes may reduce and/or eliminate latency introduced due to determining actual packet sizes.

Abstract: A gas seal for a pipe joint in an exhaust system configured to receive an exhaust gas flow from internal combustion (IC) engine includes a seal element. The seal element includes an outer surface and an inner surface arranged concentrically about a first axis. The outer surface is configured to seal against a pipe of the exhaust system. The gas seal also includes a flow-guide element fixed to the seal element at the inner surface of the seal element. The flow-guide element defines an aperture having a shape configured to direct and focus the exhaust gas flow away from the first axis. An exhaust system and a vehicle having such a gas seal are also disclosed.

Abstract: An automotive battery module with one or more battery cells and a coolant loss detection and remediation system cooperative with coolant that is configured to provide thermal management of the battery module. Coolant levels in or around the battery module may be detected, while cooperation with a controller permits corrective action in the event that a leakage of coolant is detected. The controller senses a coolant level sensor which is located in a coolant reservoir to determine when the coolant level drops below a predetermined level. When the coolant level is determined to be low, the controller reports the low level condition and takes remedial action. The controller also has a set of enablement conditions that must be satisfied before the controller senses the coolant level sensor.

Abstract: A turbocharger compressor includes a compressor housing having a housing wall that includes a shroud that defines a central air channel and a compressor inlet in fluid communication with the central channel and an inlet duct. It also includes a compressor wheel configured to draw air into the compressor inlet from the inlet duct and create a main airflow in the central air channel axially toward a compressor outlet. The compressor also includes a bypass channel that extends between an opening in the main channel located between the compressor inlet and compressor outlet proximate the compressor blades and the compressor inlet. The compressor also includes a deflector that includes a deflector surface that is configured to direct a bypass airflow in the bypass channel, and flowing in a direction from the main channel toward the compressor inlet, into the compressor inlet axially and radially inwardly toward the compressor wheel.

Abstract: A vehicle includes a body component, a rechargeable energy storage system (RESS), a traction motor, a coolant reservoir having an inlet, and a bracket. The traction motor is electrically connected to the RESS and delivers motor torque for propelling the vehicle. A lobed cap covers the inlet. The bracket extends between the lobed cap and the body component. The bracket defines an opening having radially-inward projecting tabs, each of which engages a different axial side wall of the cap between different adjacent lobes of the lobed cap to prevent rotation and removal of the lobed cap. A method includes providing the above bracket, routing a lobed cap of a coolant reservoir through the opening after installing the cap to the reservoir such that the tabs engage a different axial side wall of the cap between different adjacent lobes of the lobed cap.
