  • Patent number: 11979696
    Abstract: In some examples, a system includes an article of personal protective equipment (PPE) having at least one sensor configured to generate a stream of usage data; and an analytical stream processing component comprising: a communication component that receives the stream of usage data; a memory configured to store at least a portion of the stream of usage data and at least one model for detecting a safety event signature, wherein the at least one model is trained based as least in part on a set of usage data generated by one or more other articles of PPE of a same type as the article of PPE; and one or more computer processors configured to: detect the safety event signature in the stream of usage data based on processing the stream of usage data with the model, and generate an output in response to detecting the safety event signature.

  • Patent number: 11922892
    Abstract: The disclosed devices may include a driver circuit including a voltage boost circuit, a pulse modulation controller, and optionally a headroom processor. The voltage boost circuit may be configured to receive a device input voltage (such as a battery voltage) and generate a backlight drive voltage. The pulse modulation controller may be configured to provide a pulse modulation signal to the voltage boost circuit, and may include a digital circuit or an analog circuit. Example devices may include a backlight unit receiving the backlight voltage. The optional headroom processor may provide a headroom signal to the pulse modulation controller based on a headroom voltage determined from the backlight unit. Devices may further include a backlight unit including an arrangement of light-emissive elements, and may include display devices such as head-mounted devices. Various other methods, systems, and computer-readable media are also disclosed.

  • Patent number: 10079916
    Abstract: Systems, apparatuses, and methods for reducing inter-node bandwidth are contemplated. A computer system includes requesting nodes sending transactions to target nodes. A requesting node sends a packet that includes a register identifier (ID) in place of a data value in the packet. The register ID indicates a register in the target node storing the data value. The register ID uses fewer bits in the packet than the data value. The data value may be a memory address referencing a memory location in the target node. The received packet may also include an opcode indicating an operation to perform on the targeted data value.

  • Publication number: 20090172675
    Abstract: Systems for context switching a requestor engine during an atomic process without corrupting the atomic process. Typically an atomic process cannot be interrupted prior to completion and if it is interrupted, the process will terminated abnormally resulting in a corrupted transaction. Systems that allow for a controlled interruption of an atomic process without corruption with subsequent context switching are presented. The system consists of a context-switchable requester engine, a context switch controller, shared resource synchronizer, and a shared resource system. The system may also containing multiple local and remote context-switchable requestor engines as well as multiple local and remote shared resource systems. A method for context switching a requestor engine during an atomic process without corrupting the atomic process is also presented.
