Patent number: 7936265Abstract: A smartcard or other media detects the presence of chemical, biological, radiation, and/or explosive (CBRE) compounds or other items of interest on individuals handling the smartcard or other media. The exposure is stored such that, when the card is presented to a reader, the detection data is transmitted to the reader for appropriate processing by the system. In one embodiment, this invention provides a detection methodology which captures the fact that the holder of the detection device has been in contact with an item of interest without external power. The detector card is then able to alert appropriate authorities of that exposure when the device is presented to a reader in the normal course of the holder's business.Type: GrantFiled: May 19, 2008Date of Patent: May 3, 2011Assignee: Cubic CorporationInventors: Jon D. Macklin, Walter C. Bonneau, Jr., Raymond DeKozan, Joseph V J Ravenis, Bruce D. Roberts

Patent number: 7705712Abstract: A fast data transfer collection system using message authentication and contactless RF proximity card technology in non-contact storage and retrieval applications. The system is generally comprised of Host computers (application computer systems), Target radio frequency (RF) terminals, and a plurality of portable Tags (“smart” or “proximity” cards). A Host provides specific application functionality to a Tag holder, with a high degree of protection from fraudulent use. A Target provides control of the RF antenna and resolves collisions between multiple Tags in the RF field. A Tag provides reliable, high speed, and well authenticated secure exchanges of data/information with the Host resulting from the use of a custom ASIC design incorporating unique analog and digital circuits, nonvolatile memory, and state logic. Each Tag engages in a transaction with the Target in which a sequence of message exchanges allow data to be read(written) from(to) the Tag.Type: GrantFiled: May 19, 2006Date of Patent: April 27, 2010Assignee: Cubic CorporationInventors: Guy M. Kelly, Kevin J. Page, Don P. Plum, Joseph V J Ravenis, II

Patent number: 7437560Abstract: A secure communication link is established between a smart card and a remote central computer system through a network by using security functions at the smart card and the central computer system. A smart card communication device facilitates the exchange of data between the smart card and a local processor by modulating data signals sent from the local processor and demodulating signal transmitted from the smart card. The local processor couples the data signals to the network while maintaining the secure data in its secure state. The secure link can be used to perform a smart card transaction.Type: GrantFiled: July 23, 1999Date of Patent: October 14, 2008Assignee: Cubic CorporationInventors: Kevin J. Page, Don P. Plum, Guy M.

Patent number: 7376839Abstract: An access control system securely transfers identification and transaction information between an access reader and a contactless smart card over a contactless radio frequency link via an RF modem. The access reader contains a programmable microcontroller, DC/DC converter, regulator, Opto-Isolators and LEDS, and an RF modem. The smart cards contain identification or transaction data as well as reader programming and de-programming software, which is protected by appropriate security keys. An access reader having the appropriate security keys performs a one to one verification of data stored in the smart card to data from an identification device coupled to the access reader. Upon verification of the validity of the smart card, the access reader transfers identification and transaction information over a data link to any external processor or controller which controls access to a secured area.Type: GrantFiled: May 6, 2002Date of Patent: May 20, 2008Assignee: Cubic CorporationInventors: David R. Carta, Guy M. Kelly, Joseph V J Ravenis, II

Patent number: 6801787Abstract: A transceiver assembly is designed to receive a controller module or to be inserted into a controller module to form a portable smart card communication device. The transceiver assembly includes a transceiver and a connector to electrically connect the controller module to the transceiver. The controller module establishes a communication link between itself and a smart card by sending and receiving signals and data through the connector. Information is read from the smart card and forwarded to the controller module. Information is transmitted through the transceiver assembly and stored on the smart card. The controller module can easily be disconnected from the transceiver assembly for use with other transceiver assemblies.Type: GrantFiled: November 21, 2000Date of Patent: October 5, 2004Assignee: Cubic CorporationInventors: Kevin J.

Patent number: 6259769Abstract: A controller module is releasably received in a cradle portion of a transceiver assembly to form a portable smart card communication device. The transceiver assembly includes a transceiver and a connector to electrically connect the controller module to the transceiver. The controller module establishes a communication link between itself and a smart card by sending and receiving signals and data through the connector. Information is read from the smart card and forwarded to the controller module. Information is transmitted through the transceiver assembly and stored on the smart card. The controller module can easily be removed and used with other transceiver assemblies.Type: GrantFiled: May 4, 1999Date of Patent: July 10, 2001Assignee: Cubic CorporationInventors: Kevin J.

Patent number: 6010074Abstract: A collision resolution system and method for enhanced non-contact automated data collection. The data collection system generally includes a plurality of portable fare tags or token ("smart") cards and a stationary target terminal. Each tag exchanges a series of messages with the target terminal to establish a communication link for the transfer of financial or other data. Concurrently, each tag and the target terminal process the messages to provide collision resolution, thereby ensuring that only one tag, at any instance, establishes the communication link with the target.Type: GrantFiled: April 1, 1997Date of Patent: January 4, 2000Assignee: Cubic CorporationInventors: Guy M.
