Abstract: A system for use in a park attraction to provide collaborative driving experiences. The system includes a vehicle including a body with passenger seats, including a user input assembly proximate to each of the passenger seats, and further including a holonomic drive system adapted to move the body in any direction while riding on a driving surface of the park attraction. The system also includes a system controller (running an attraction/game control module) that operates to: (a) receive user input from each of the user input assemblies; (b) process the user input from each of the user input assemblies to generate a control vector associated with each of the user input assemblies; (c) combine the control vectors from all of the user input assemblies to generate a resultant vector; (d) generate a drive control signal from the resultant vector; and (e) transmit the drive control signal to the vehicle.

Abstract: A system for improving navigation of robots in a space with a plurality of pedestrians or other movable objects or obstacles. The system includes a traffic analysis assembly that has a traffic sensor(s) sensing movement of the obstacles in the space. The traffic analysis assembly further includes a processor running a flow module that processes (such as the Gunnar-Farneback optical flow algorithm) output from the traffic sensor to generate traffic analysis results, which include density values for the obstacles in the space and motion information for the obstacles in the space (e.g., speed and direction). The system includes a robot with a controller running a navigation module selecting a navigation route between a current location of the robot and a target location in the space using the traffic analysis result. The workspace is configured such that the obstacles such as pedestrians have unregulated flow patterns in the space.

Abstract: An augmented reality (AR) system that enhances an AR participant's experience by providing a visual effect with added depth. The AR system displays previously achieved by an AR HMD are augmented with a second layer of accessible depth. This added depth is achieved by including, in the AR space/real world environment, external stereo screens upon which 3D stereo content is projected by one or more 3D projectors. The AR HMD is equipped with an external 3D screen viewing assembly so the AR HMD allows an AR participant wearing the AR HMD to view images on the external stereo screens in stereo. The external stereo screens can be used to produce 3D imagery that may differ in depth from the depth of the fixed focal length images displayed to the viewer by the AR HMD. The AR system enlarges the AR participant's simultaneous angular viewing range to 55 to 160 degrees.

Abstract: Aspects described herein include a user display unit that determines a portion of a presentation currently being viewed by a user through a transparent display. For example, if the display area is a theater screen, only a portion of the screen may be viewable to the user through the transparent display. The display unit may display metadata on the transparent display with a spatial relationship to one or more objects in the presentation. For example, the display unit may output a text bubble near an actor in the presentation that provides an interesting fact about the actor which may overlay or occlude the presentation. In one aspect, if the object in the presentation moves or the display unit is reoriented, the display unit may move the metadata to maintain the spatial relationship between the object and the metadata in the transparent display.

Abstract: A safety platform for repair of a hydraulic elevator adapted to be attached to an underside of the elevator car to militate against vertical movement of the elevator car while repairs are being conducted on the hydraulic elevator.

Abstract: Circuitry compensating for inherent nonlinearities in the tuning voltage sensitivity of varactor tuners, thereby providing relatively constant AFC pull-in range throughout the band of operating frequencies, is shown. In both the VHF and UHF bands, the AFC system develops an error correction voltage in proportion to the tuning voltage. With respect to reception of VHF channels, a gain switching circuit operates to reduce the proportion of AFC error correction voltage developed on a High Band VHF channel, thereby compensating for increased tuning voltage sensitivity on High Band VHF. With respect to reception of UHF channels, a tuning voltage sensing circuit operates to effect an error correction voltage that is a greater proportion of the tuning voltage when the tuning voltage is above a pre-determined value corresponding to approximately channel 60.

Abstract: For the handling, especially sorting, of devices which at least partly consist of a ferromagnetic material, at least one switchable electromagnet in a fixed position produces an electromagnetic field which penetrates a first steady magnetic field and is dimensioned and timely switched according to the special handling process to be performed.
