  • Patent number: 10312979
    Abstract: A wireless access point device wirelessly communicates with a plurality of wireless client devices. The wireless access point includes a central processor subsystem and a plurality of transceiver devices each including a plurality of antennas, and a plurality of radio transceivers, each of the plurality of transceiver devices configured for deployment throughout a coverage area, each transceiver device being connected to the central processor subsystem via a respective cable. The central processor subsystem distributes in-phase and quadrature baseband samples across the plurality of transceiver devices associated with traffic to be transmitted and received via the plurality of transceiver devices in one or more frequency bands so as to synthesize a wideband multiple-input multiple-output transmission channel and a wideband multiple-input multiple-output reception channel. The access point transmit and receive functions are “split” or partitioned across the plurality of transceivers devices.

  • Patent number: 10159344
    Abstract: A pull-out drawer guide having a cabinet rail for attaching to a furniture cabinet, a drawer rail for attaching to a drawer, a roller carriage having rollers, which, during relative movement of the rails, roll on a guide face of the respective rail. The pull-out guide includes on the cabinet rail, an automatic retraction mechanism which, by means of a catch element, catches the drawer rail in a closure movement and moves it to a closed position relative to the cabinet rail. The cabinet rail has a stop element, and the drawer rail has an abutment element, wherein, at a catch position of the cabinet rail, a distance between the stop and abutment elements is smaller than a maximum length of movement of a coupling element of a force accumulator of the automatic retraction mechanism, the distance being parallel to a direction of movement of the drawer rail.
