  • Patent number: 6956472
    Abstract: There is disclosed an automobile hang tag for use in parking control and the like with an integral radio transponder, together with interrogator apparatus associated therewith in a system for parking control or other purposes. The detection range for the RFID interrogator and transponder is at least about six meters (20 feet) to enable rapid control monitoring of parking facilities from a moving vehicle through the back window or front windshield of parked vehicles. Reliable and trouble-free monitoring of the hang tags in a customary rear view mirror location is facilitated by employing directional antennas in the RFID hang tags, increasing the antenna gain while suppressing false signals and noise and improving the range-to-power ratio for the system. The RFID hang tags may be battery powered but are preferably unpowered RFID transponders.

  • Patent number: 4909399
    Abstract: There is disclosed a ticket rack for tickets to performances of sports events in a readily accessible manner which is modular in form so that the modules can be arranged together providing many individual compartments for respective rows, sections or the like of theaters or arenas. The compartments are arranged in rows and columns similar to office desk pigeonholes, but are obliquely oriented for greater convenience, and a particular feature of the apparatus provides removable vertical dividers or partitions between certain of the compartment columns whereby their widths may be adjusted to accommodate two or more different widths of admission tickets. Thus the racks may not only be combined in a manner to best facilitate selection of particular tickets in a particular theater or arena, but also each rack module may be adjusted for different sizes of tickets by rearranging the removable partitions.
