Abstract: A system, method, and communication device are disclosed. The system can include an optical interrogator and a phase-modulating communication device. The communication device can include a retro-optimized lens, a phase modulator, and a processor. The retro-optimized lens can be a non-imaging optical arrangement configured to minimize deviation between an incoming signal and a reflected signal used for return link communications. The processor can be configured to calibrate a modulation path length of the communication device based on a wavelength of the communication signal and can control an operation of the phase-modulator to send phase-coded messages to the interrogator. Optionally, the processor can perform a real-time phase calibration of the communication device using feedback from the interrogator.

Abstract: A system for implanting a wire antenna in a contactless smart card includes an ultrasonic implanting head with a voice-coil actuator to control the pressure at which a heated wire is forced into a plastic card substrate. The force produced by the actuator is proportional to the current in a coil winding in the actuator. A controller uses a feedback system to maintain a relatively constant applied pressure. The feedback system monitors the current in the coil and the controller issues electronic signals to increase or decrease the current in the coil in response to the monitored current.

A user generates a CAD drawing representative of a desired smart card design. A robotic system uses the information in the CAD drawing file, e.g., Cartesian coordinates representative of desired feature dimensions and locations on the card, to control robotic systems to produce the desired feature in a smart card assembly.

Abstract: In an embodiment, a weld head for use in bonding antennas to IC modules in a sheet of smart card modules includes an integrated test unit, e.g., a reader/writer (R/W) unit. The test unit tests the bonds between the antenna and the IC module in a selected card module by attempting to communicate with the IC module with low-wattage RF waves via the card module's antenna.
