  • Publication number: 20240378062
    Abstract: Within an integrated circuit including a processor system and a data processing array, one or more kernels in the processor system are executed in response to a scheduling request from a host data processing system. The one or more kernels receive configuration data for implementing trace or profiling of a user design executable by a plurality of active tiles of the data processing array. Using the one or more kernels, selected tiles of the plurality of active tiles of the data processing array are configured with the configuration data to perform the trace or the profiling. Trace data or profiling data is generated through execution of the user design by the data processing array. The one or more kernels provide the trace data or the profiling data to the host data processing system.

  • Publication number: 20240378358
    Abstract: Hardware event trace windowing for a data processing array includes executing a user design using a plurality of active tiles of a data processing array disposed in an integrated circuit. A trace start condition is detected subsequent to a start of execution of the user design. In response to the trace start condition, trace data is generated using one or more of the plurality of active tiles of the data processing array. A trace stop condition is detected during execution of the user design. In response to the trace stop condition, the generating the trace data by the one or more of the plurality of active tiles is discontinued.

  • Publication number: 20240354223
    Abstract: Event trace includes implementing a design for a data processing array of a target integrated circuit (IC) by, at least in part, adding a trace data offload architecture to the design. One or more selected tiles of the data processing array used by the design as implemented in the target IC are configured to generate trace data based on user-specified runtime settings for performing a trace. During execution of the design by the data processing array, trace data as generated by the one or more selected tiles of the data processing array is conveyed to a memory of the target IC using the trace data offload architecture. A trace report is generated from the trace data using a data processing system coupled to the target IC.

  • Publication number: 20240347948
    Abstract: A replaceable DIN connector receptacle is provided that may be removably attached to a connector board and coupled with medical equipment in the field, without requiring the connector board or the equipment in which the DIN connector receptacle is housed to be opened. The replaceable DIN connector receptacle allows easy service and maintenance of medical equipment in the field. Relative to convention, DIN connector(s) are removed from the housing of the remaining medical equipment, placed in its own separate housing that is dedicated to just housing the DIN connector(s), and placed in electrical communication with the medical equipment through a dedicated wired or wireless connection.

  • Patent number: 12109158
    Abstract: Systems, devices and methods are described for mounting medical equipment on IV poles, bed rails and other supporting structures in medical facilities including operating rooms and critical care sections. A system including a mounting hanger and corresponding equipment housing is disclosed that allows quick mounting and dismounting of equipment from a supporting structure.

  • Publication number: 20240330144
    Abstract: Offloading trace data from an integrated circuit (IC) can include receiving, by a high-speed debug port (HSDP) trace circuit, streams of trace data from a plurality of compute circuits of different compute circuit types. The compute circuits and the HSDP trace circuit are disposed in a same IC. Compute circuit type identifiers are included within the trace data. The compute circuit type identifiers specify the compute circuit type from which respective ones of the streams of the trace data originate. Debug trace packets (DTPs) are generated from the trace data and transmitted over a high-speed communication link to a trace data storage device (TDSD) external to the IC. Within the TDSD, trace data from the DTPs are stored in a memory of the TDSD.

    Abstract: A connector receptacle for connecting with a corresponding connector plug coupled with electrodes being used for performing EMG procedure on a patient is provided. The receptacle includes a first ball bearing pressing against a first end of a housing of the plug and, preferably, a second ball bearing pressing against a first end of the housing of the plug when the plug is connected to the receptacle for exerting a retention force against the plug. The first and the second ball bearings are pressed against the first and the second ends respectively by using a spring force generated, for example, by a retention band.

  • Patent number: 11949188
    Abstract: Systems, devices and methods are described for connecting multiple electrical connectors as a group with corresponding receiving sockets, or connection ports, in a medical device. A multiple electrical connector plate acts as an intermediate connector for quickly engaging or disengaging a group of electrodes with the corresponding device as a single unit. The connection plate includes multiple sections that allow a connector to be snapped securely in place on the connection plate such that the connector does not pull or push free from its snapped in location, resulting in group handling of electrical connectors that is less time consuming, reduces errors and positively impacts the quality of medical care.
