Publication number: 20140289023Abstract: Techniques are provided herein that enable local fare processing for access control points (entry gates, turnstiles, etc.) in a transit or similar system that can detect fraudulent activity far more quickly than fare processing systems using traditional blacklists or whitelists—and even detecting fraudulent activity at a first occurrence. Embodiments take advantage of the relatively high communication speed and memory capacity of modern transit systems to generate a list of all applicable cards with usage data such as the time of last use, value, or other “one directional data,” provide it to each access control point in the system. The access control point, upon reading fare media, can then compare the data on the fare media to data on the list to determine whether fraud may be taking place. The access control point may then determine whether to allow access, flag the fare media, and/or take another action.Type: ApplicationFiled: March 20, 2014Publication date: September 25, 2014Applicant: CUBIC CORPORATIONInventor: Thomas Busch-Sorensen

Publication number: 20140287691Abstract: Systems and methods are provided for enhancing a signal for load modulation from reading a smartcard. According to such methods, an antenna signal is generated by transceiver circuitry. An antenna signal field associated with the antenna signal can be transmitted. A reference signal that is substantially constant in amplitude and phase and substantially in phase with a carrier frequency of the antenna signal can be generated. A modulated antenna signal can be received. The modulated antenna signal can include the antenna signal that has been modulated as a result of the presence of a smartcard within the antenna signal field. The reference signal can be subtracted from the modulated antenna signal to produce a resultant signal. The resultant signal may be provided to receiving circuitry of the transceiver circuitry.Type: ApplicationFiled: March 20, 2014Publication date: September 25, 2014Applicant: CUBIC CORPORATIONInventor: Thomas Busch-Sorensen

Patent number: 8350668Abstract: Techniques for protecting communication between a card reader and a contactless smartcard are disclosed. In one embodiment, a protocol transmitter includes a transmit circuit and a processor. The transmit circuit is configured to generate a blocking signal having a frequency used by the card reader to communicate with the contactless smartcard. The processor is coupled to the transmit circuit and configured to modulate the blocking signal according to a communication protocol of the contactless smartcard. A first antenna of the protocol transmitter is disposed a predetermined distance from the card reader and is coupled to the transmit circuit to radiate the blocking signal. Optionally, the processor modulates the blocking signal so as to simulate a data exchange between the card reader and the contactless smartcard.Type: GrantFiled: July 15, 2009Date of Patent: January 8, 2013Assignee: Cubic CorporationInventor: Thomas Busch-Sorensen

Patent number: 8240561Abstract: Techniques for authenticating a contactless smartcard in a card processing system are disclosed. A card reader measures an impulse response associated with the contactless smartcard during outbound modulation of an RF carrier and compares measured impulse data to reference impulse data. The reference impulse data can be stored at the card reader or obtained from the contactless smartcard in an encrypted form. Optionally, the card reader issues one or more challenges to the contactless smartcard in connection with a card transaction and verifies a response to the one or more challenges using calibration data. The card reader can determine the card's authenticity based on the impulse data, the response to one or more challenges, or a combination thereof.Type: GrantFiled: March 1, 2010Date of Patent: August 14, 2012Assignee: Cubic CorporationInventor: Thomas Busch-Sorensen

Patent number: 7116956Abstract: An RF power oscillator for contactless card antennas shapes a carrier signal at the operating frequency utilizing a delay circuit having a number of taps for delaying the carrier signal by different lengths of time. The delayed signals are input into a buffer and output through impedance elements to a node coupled to the antenna. The resulting waveform for a square wave input signal, and equal-length delay taps, is a trapezoidal wave output. Any input wave form can be shaped in a variety of ways depending upon the combinations of delay taps used. Since the buffer drivers for each delayed wave switch state at slightly different times, the amplitude and bandwidth of emitted electromagnetic interference (EMI) is reduced for the transmission circuit.Type: GrantFiled: September 11, 2003Date of Patent: October 3, 2006Assignee: Cubic CorporationInventor: Thomas Busch-Sorensen

Patent number: 5085772Abstract: A filter for filtration of fluids includes a filter cloth arranged in a housing with an inlet and an outlet. An acoustic field produced by an acoustic transducer, can act on the filter cloth. The invention the filter cloth is arranged substantially in a pressure node, i.e. a velocity antinode, of the acoustic field. As a result, a relatively inexpensive filter is obtained which is economical to operate due to the long durability of the filter.Type: GrantFiled: September 14, 1990Date of Patent: February 4, 1992Assignee: Eskofot A/SInventor: Thomas Busch-Sorensen
