Abstract: A monitoring system includes a wireless identification tag and interrogator. The tag includes memory that stores information associated with a person or object associated with the wireless identification tag. The interrogator wirelessly transmits an interrogation signal, which includes a sequence of interrogation codes, to the wireless identification tag. If one of the interrogation codes is associated with the wireless identification tag, the tag wirelessly transmits an acknowledgment signal associated with the tag. The interrogator receives the acknowledgment signal, which indicates that the wireless identification tag has been monitored within an area.

Abstract: A wireless high speed data communication system having a host radio station connected to a source of data. The host radio station transmits data to a radio repeater that is within a line of sight. The communication system may include numerous repeaters each of which is configured to communicate with each other within a line of sight. The repeaters are also configured to communicate with users by a direct electrical connection and a line of sight wireless connection. The users may also be electrically connected to a local area network for further distribution of the data.

Abstract: A device for taking aerial motion pictures, includes a camera (3) disposed at the upper end of a vertical periscopic tube (2) whose lower end (1) projects below a carrying airplane. An optical device is provided, adapted to effect vertical sweeping by pivoting about a horizontal axis. The periscopic tube (2) can pivot about its vertical axis and the camera (3) can pivot coaxially relative to the periscopic tube (2). The periscopic tube (2) is carried by a first turning plate (41) mounted rotatably on a fixed plate (40) and driven in rotation by a motor (43), whilst the camera (3) is carried by a second turning plate (51) mounted for rotation on a second fixed plate (50) and driven in rotation by a second motor (53).

Abstract: A combination flying toy/beverage can insulator comprising an insulating cylinder and weighted nose ring for fixing the center of gravity of the device at a point about 12% to 18% of the full length of the device distal from the leading edge of the device.

Abstract: There is disclosed a video game apparatus to be employed by a passenger of an airplane. The apparatus includes a tray which is mounted on the rear of an airplane seat. The tray has an internal hollow with a rectangular aperture on a top surface which surface faces the passenger when the tray is placed in a usable position. Located in the rectangular aperture is a TV display screen. Located in the internal hollow of the tray is a video game apparatus which operates to provide a video game display on the surface of said TV display screen. The surface of the tray containing the TV display screen also includes a plurality of control elements which are coupled to the video game apparatus to enable the passenger to operate the game. To energize the game, the tray contains a cable coupling assembly whereby when a cable is inserted into the assembly, the video game is energized to provide a display of a game selected by means of a selector switch also mounted on the top surface of the tray.
