  • Patent number: 11934770
    Abstract: Embodiments described herein are directed to an annotation system having a remote processor, and a client processor in data communication with the remote processor. The client processor is adapted to send a first request for an electronic file to the remote processor, receive the electronic file from the remote processor, define at least one new annotation about the electronic file, and define at least one anchor associated with the at least one annotation. The at least one of the remote processor and the client processor is adapted to store the at least one anchor and the at least one annotation in an annotation file that is separate from the electronic file.

  • Publication number: 20240057895
    Abstract: A physiological monitor uses patterns of motion during strength training activity, e.g., as detected by a wearable monitor, to evaluate a degree of muscular, musculoskeletal, and/or biomechanical strain experienced by a user while engaged in strength training. The resulting strain may advantageously be quantified and used to provide coaching recommendations, update daily strain metrics, and take other responsive actions.

  • Patent number: 10003405
    Abstract: A Data Over Cable Service Interface Specifications (DOCSIS) Passive Optical Network (PON) system (DPON) makes optical subscribers appear as cable subscribers. In one embodiment, a Cable Modern (CM) proxy is located in an Optical Line Termination (OLT). The OLT implements a cable modem protocol stack that operates as the CM proxy and communicates with a back office system. The OLT translates the data retrieved by the CM proxy into Optical Network Unit (ONU) recognizable commands, and sends the translated data to the ONU. In a second embodiment, the CM proxy is located in the ONU. The ONU implements the cable modern protocol stack that operates as the CM proxy and communicates with the back office system. The ONU translates the data retrieved by the CM proxy into ONU recognizable commands and sends the translated data to the ONU.
