Abstract: A valve assembly comprising a valve body, a valve housing, and a spring member coupling the valve body to the valve housing. The spring member is configured to align the contact surface of the valve body with the valve seat inside the valve housing. The spring member can be located on the discharge side of the valve body. The valve assembly may be disposed in a fluid end of a positive displacement pump that is operated to flow a wellbore servicing fluid into a wellbore.

Abstract: An example electronic security tag attachable to an item includes a tag body member, a connecting member having a pin portion releasably engageable with the tag body member, the pin portion extending along a first axis. The electronic security tag further includes a locking member to lock the connecting member to the tag body member. The locking member includes a clutch mechanism movable parallel to the first axis between a first position in contact with the pin portion and corresponding to a locked state and a second position corresponding to an unlocked state. The locking member further including a rotational drive member configured to rotate and interact with a plunger member of the clutch mechanism to move the clutch mechanism from the locked state to the unlocked state.

Abstract: A vehicle safety system is for preventing child abandonment in a vehicle. The vehicle safety system may include a controller coupled to a flow sensor, a temperature sensor, and a seat sensor. The controller may be configured to detect when the vehicle is in a fueling state based upon the flow sensor, detect occupancy of a child safety seat based upon the seat sensor, and detect when a driver side door is in an open state based upon a driver side door sensor in the vehicle. The controller may be configured to when the driver side door has entered the open state, when the child safety seat is occupied, and when the vehicle does not enter the fueling state within a time period, then cause the vehicle to enter an alert state.

Abstract: A hardware accelerator that is efficient at performing computations related to tensors. The hardware accelerator may store a complementary dense process tensor that is combined from a plurality of sparse process tensors. The plurality of sparse process tensors have non-overlapping locations of active values. The hardware accelerator may perform elementwise operations between the complementary dense process tensor and an activation tensor to generate a product tensor. The hardware accelerator may re-arrange the product tensor based on a permutation logic to separate the products into groups. Each group corresponds to one of the sparse process tensors. Each group may be accumulated separately to generate a plurality of output values. The output values may be selected in an activation selection. The activation selection may be a dense activation or a sparse activation such as k winner activation that set non-winners to zeros.

Abstract: A hardware accelerator that is efficient at performing computations related to a sparse neural network. The sparse neural network may be associated with a plurality of nodes. One of the nodes includes one or more sparse tensors. The accelerator may compress the sparse tensor to a dense tensor. The sparse tensor may also be structured so that the dense locations in the tensor are blocked or partitioned. The accelerator may transpose the weight tensor and align the partitions of the tensor with the hardware architecture. The structured tensor has a balanced number of active values so that the active values can be processed by an efficient number of operating cycles of the accelerator. The accelerator may also perform bitwise and operation to determine the location of dense pairs in two sparse tensors to reduce the number of computations.

Abstract: A hardware accelerator that is efficient at performing computations related to a sparse neural network. The sparse neural network may be associated with a plurality of nodes. An artificial intelligence (AI) accelerator stores, at a memory circuit, a weight tenor and an input activation tensor that corresponds to a node of the neural network. The AI accelerator performs a computation such as convolution between the weight tenor and the input activation tensor to generate an output activation tensor. The AI accelerator introduces sparsity to the output activation tensor by reducing the number of active values in the output activation tensor. The sparsity activation may be a K-winner approach, which selects the K-largest values in the output activation tensor and set the remaining values to zero.

Abstract: A device for supporting a patient's arm includes a rail clamp configured to be secured to a rail or other structure on a table such as an operating table. The rail clamp includes a clamp body and a socket configured to receive a base on an attachment such as a lateral brace. The base may be inserted longitudinally in the longitudinal socket on the rail clamp. The base may comprise an arm brace. The base is moveable in the longitudinal socket such that the arm brace may be raised or lowered relative to the rail clamp. The arm brace may be used when a patient is lying prone or laterally on a table.

The controller may be configured to if the vehicle does not enter the fueling state within a first time period, then cause the vehicle to enter a first alert state, and if the vehicle does not enter the fueling state within a second time period greater than the first time period, then cause the vehicle to enter a second alert state.

Abstract: A method and system is presented for coordinating the transmission of supplemental digital data to accompany broadcast data, and in particular, analog radio broadcasts, among a plurality of broadcasters. The supplemental digital data may provide information about the particular broadcast data being transmitted (i.e. cut data) or may be supplemental to such data (i.e. news, weather and traffic data). The supplemental digital data to be presented is sorted based on particular algorithms which may take into account broadcaster-specified criteria such as target audience, time of day, type of broadcast data presented, and the like. The supplemental digital data may be audio data, visual data, or audio-visual data for presentation with the broadcast data. The supplemental digital data may further be advertisement data. The advertisement data may be sold by the broadcasters or the party coordinating the IBOC transmission of the supplemental digital data.
