  • Publication number: 20230199111
    Abstract: A system for data recording across a network includes a session border controller connecting incoming data from the network to an endpoint recorder. A load balancer is connected to the network between the session border controller and the endpoint and receives the incoming data from the session border controller, wherein the load balancer comprises computer memory and a processor configured to parse the incoming data into video data and audio data according to identification protocols accessible by the processor from the computer memory. A recording apparatus includes recording memory that receives the incoming data from the load balancer, stores a duplicate version of the incoming data in the recording memory, and connects the incoming data to the endpoint.

  • Patent number: 11300165
    Abstract: Electromagnetically-operated coupling device for selectively connecting and disconnecting a first rotating member and a second rotating member in a driveline of a vehicle is disclosed, wherein the first and the second rotating members are coaxial with each other and rotatable about a same axis of rotation. The coupling device comprises: an engagement sleeve provided with a control disk made of a ferromagnetic material, the engagement sleeve being axially slidable between an engaged position and a disengaged position; and a control system for controlling the sliding movement of the engagement sleeve between said engaged and disengaged positions. The control system comprises a pair of magnetic coils which are placed on opposite sides of the control disk, coaxially therewith, and are arranged to be selectively activated by an electric current to generate a magnetic force acting on the control disk to axially move the control disk, and therefore also the engagement sleeve, in either directions.

  • Publication number: 20210387259
    Abstract: Atomic Layer Deposition (ALD) and Molecular Layer Deposition (MLD) provide precise and conformal coatings that are employed to modify the properties of powders for additive manufacturing (AM). We have surprisingly discovered that use of a limited number of ALD cycles can impart improved flowability. In various aspects, the coating may provide one or more advantages such as novel material properties, increased flowability, improved sintering, enhanced stability during storage, and prevention of premature sintering.
