Abstract: Techniques for CSC detection and selection include generating a radio frequency (RF) field that defines a range of communication for the CSC reader, transmitting a signal in the RF field, and detecting a modulation in the RF field indicating that a first CSC is within the RF field and has responded to the signal. The modulation is inspected for collision, wherein collision occurs if more than one CSC within the RF field responds to the poll signal. After determining that the modulation does not contain a collision, a halt command is transmitted to the first CSC instructing the CSC to only respond to one or more specific commands.

Abstract: Systems and techniques are presented for determining the position of a mobile device. The mobile device receives two beacon packets transmitted at varying power levels by a first beacon and determines received signal strength (RSS) levels for the beacon packets. A maximum distance and a minimum distance are determined based on the power levels that the packets were transmitted at and the RSS levels that the packets were received at. An area around the first beacon is determined based on the distance range. The mobile device receives two additional beacon packets transmitted at varying power levels by a second beacon and determines RSS levels for the beacon packets. A distance range between the mobile device and the second beacon is determined and an area around the second beacon is determined based on the distance range. The area of overlap between the beacons is where the mobile device is positioned.

Abstract: 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.

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.

Abstract: 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.

Abstract: A method for fabricating a grid-stiffened panel which incorporates a network of fluid channels and passageways into the ribs and face sheet is described. The method is comprised of a base tooling assembly, an expansion tooling assembly, a composite prepreg, plugs, a face sheet and a network of valves and pumps, wherein the prepreg is draped over said expansion tooling and assembled with the base tooling assembly to form a rib structure. Channel plugs are placed therein such that gaps between adjacent expansion tooling blocks are filled, and the entire rib structure assembly is autoclaved. The face sheet may be comprised of a plurality of layers, whereby channels are machined into the lower layer(s). The upper layer(s) are bonded to the lower layer(s) to seal the channels, and said face sheet is bonded to the rib structure.
