Abstract:
A security mark having multiple optically orthogonal coaligned bar codes is produced using a reflection hologram visible substantially at only a first wavelength that is layered over a wavelength sensitive filter, which blocks light transmission at the first wavelength but transmits light at a second wavelength, and having beneath it an additional bar code visible through the hologram and the wavelength sensitive filter at the second wavelength. A validation means reads multiple holographic bar codes with light at the first wavelength by illuminating the hologram separately from multiple directions, and further reads the bar code beneath the wavelength sensitive filter by illuminating the mark with light of the second wavelength. By suitable choice of multi-directional and multi-wavelength illumination, multiple coaligned bar codes may be read in the same physical location with no mutual interference.
Abstract:
An electronic security key is particularly adapted to exchange electronic data with an electronic coin acceptor circuit of a coin acceptor to enable the coin acceptor for coin programming. The electronic security key includes an electronic security key circuit defined by subcircuits including (1) circuitry for exchanging electronic data with an electronic coin acceptor, (2) encryption generating circuitry for generating encrypted password data at a sufficient value to generate authentication data from at least a portion of the electronic data transmitted to the electronic security key circuit, and (3) circuitry for transmitting the generated authentication data to an electronic coin acceptor circuit to thereby enable the electronic coin acceptor circuit for coin programming thereof.
Abstract:
An electro-optical detection system for detecting objects within the boundaries of a monitored zone, comprises a plurality of LED emitter and photodetector pairs. Each emitter (12) emits a beam of pulses of light energy into the monitored zone, and its paired photodetector (14) detects light energy including light energy from the beam that is reflected from an object within the monitored zone and generates light detection signals. A controller (10) operates the emitter and photodetector pairs and evaluates the light detection signals to discriminate between light energy of beams reflected from an object within the monitored zone and other light energy. The controller can selectively adjust the evaluation of the light detection signals to adjust the effective boundaries of the monitored zone.
Abstract:
An electronic control system (10) for use in controllably unlocking a locked drawer. Portions of the system (10) are located in the vicinity (12) of the locked drawer and portions are located in a remote location ( 11 ). The system (10) includes an operator accessible switch (14) located in the remote location (11), which switch enables two separate, parallel, redundant unlocking mechanism paths. Each path includes a time delay unit (17) that delays the opening of the locked drawer until a predetermined period of time following activation of the system by the operator, in order to allow time for the operator to move from the remote location to the locked drawer. In addition to providing power to circuitry that unlocks the locked drawer, the system also provides from the remote location, and then decodes at the locked drawer location, an authorization signal. Without this signal, the unlocking circuitry will not unlock the drawer, even in the presence of power.
Abstract:
Methods of cashless gaming and player tracking use buttonless RFID technology at both gaming machines and gaming tables to transfer a predetermined denominated amount of credit from a remote network connected gaming account server to the gaming machine or table. Gaming machines have an Idle State, an anonymous credit state, and an identified credit state, each with specific methods for changing from one to another. Gaming tables have a keypad for the dealer, RFID readers at each seating position, and a transaction display visible to the dealer, the patrons, and an overhead security camera.
Abstract:
A system and method for enabling patrons at large-scale spectator events at confined venues having identifiable seats utilizes conventional or special hand-held, wireless communication devices to self-order food, drink and souvenir items from remote order fulfillment locations within the venue for delivery to identified seats. Hierarchical menus are provided for display of items for purchase on the devices. A seat identification code is associated with the order when transmitted via the existing telecommunications and Internet infrastructure. Receipt of the order is acknowledged, and a confirmation code is sent upon receipt of order delivery. There is automatic electronic payment for the order charged to a patron account that is established by prearranged means.
Abstract:
A token for use with a token operated device includes a plurality of predetermined optical characteristics. The plurality of predetermined optical characteristics are disposed in a substantially radially symmetrical manner with respect to the token, and each of the optical characteristics have the property of a facet wherein an effective surface normal of said facet is a line along a predetermined vector angle with an elevational angle ranging preferably between 30.degree. and 60.degree.. An azimuthal angle of the facet surface is other than substantially along a radial line of the token or substantially along a line tangent to an annular ring centered on the token such that a token operated device can validate the predetermined optical characteristics substantially independent of token orientation. A token testing apparatus includes a chute defined by a field adjustable pair of spaced token edge guides spaced a predetermined distance from each other such that each token passing through the chute is sensed along its center.
Abstract:
A method and apparatus are disclosed which allow for the detection of an object (14) by the generation of a radiated beam (18) and a subsequent reflection by the object (14) of a portion (20) thereof. The detection of particulate object material (16) due to a reflection of a portion (22) of the generated beam (18) is minimized.

Abstract:
A transceiver for reading RFID tags has a ferrite core antenna substantially circular in cross-section having a transmitting and receiving face producing substantially no RF energy below a plane of the transmitting and receiving face outside a peripheral surface of the ferrite core. A portion of the transceiver enclosure which passes through a mounting panel opening functions as light pipe for conducting LED indicator light in a substantially radially symmetrical manner to illuminate a sensing surface of the transceiver.
