  • Publication number: 20200058152
    Abstract: A mixed reality system that includes a device and a base station that communicate via a wireless connection The device may include sensors that collect information about the user's environment and about the user. The information collected by the sensors may be transmitted to the base station via the wireless connection. The base station renders frames or slices based at least in part on the sensor information received from the device, encodes the frames or slices, and transmits the compressed frames or slices to the device for decoding and display. The base station may provide more computing power than conventional stand-alone systems, and the wireless connection does not tether the device to the base station as in conventional tethered systems. The system may implement methods and apparatus to maintain a target frame rate through the wireless link and to minimize latency in frame rendering, transmittal, and display.

  • Patent number: 9863443
    Abstract: A multistage ejector has a nozzle arrangement, which has at least three nozzles which are arranged in series in the direction of a longitudinal axis, wherein the nozzles are designed for passage of a throughflow of a fluid, wherein a fluid gap is provided between adjacent nozzles in each case, wherein at least two of the at least three nozzles are interconnected monolithically to form a nozzle string, and wherein the nozzle string is arranged at least partially in a sleeve and the nozzle string and the sleeve are detachably fastened to each other. The nozzle string and the sleeve are axially fastened to each other by fastening mechanism which acts in a positively locking manner.

  • Patent number: 9758323
    Abstract: Needle gripper features a gripper unit with a gripping surface facing a workpiece to grip, and a needle carriage with a gripping needle. The needle carriage moves into an active position extending the gripping needle beyond the gripping surface by one needle stroke depth, and in a passive position retracting the gripping needle, and features a drive unit with a drive actuator driven forward/backward along a drive direction that couples to the needle carriage so it moves into the passive/active positions by driving the drive actuator forward/backward. A setting device for setting the needle stroke depth includes a guide carriage displaceable perpendicularly to the drive direction along a guide direction, and a stop for the guide carriage. The drive actuator couples via connection arm to the guide carriage so when the drive actuator moves backward, the guide carriage moves in the direction toward the stop, which prevents further backwards movement.

  • Patent number: 8267386
    Abstract: A pneumatically actuated area vacuum gripper for gripping and, if necessary, separating workpieces is provided by the present disclosure. In particular, the vacuum gripper is used with thin, flexible workpieces, and has a suction chamber, which has a suction wall with perforations, to be placed on the workpiece. An ejector nozzle has a connection and an outlet, the ejection nozzle being connected to the suction chamber via its connection, and the outlet of the ejector nozzle opening to the outside or into an exhaust air duct, and the suction inlet of the ejector nozzle empties into the suction chamber, whereby the direction of the air stream in the connection coming from the suction chamber corresponds to the direction of the main air conveyance in the ejector nozzle.
