摘要： 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.

摘要： Embodiments of methods and devices are disclosed for enabling network devices to join a network. These embodiments generally include a first network device, which is joined to the network, sending authentication information. If the authentication information is determined as valid by a second network device, the second network device sends a join request toward the first network device. During or after the joining process, the first and second network devices can share scheduling information. These embodiments enable a network to have additional security while consuming low amounts of power.

摘要： Systems and methods are provided regarding an optical communication system for both short- and long-range applications employing specialized diffusive elements. An interrogator unit can utilize a diffusive element that diffuses a portion of the laser beam for short-range applications. Other portions of the beam can have low divergence to enable long-range functionality as well. A response unit can utilize a diffusive retroreflector to help ensure sensors coupled to the interrogator unit detect a reflected beam. The interrogator unit can employ a plurality of sensors for sensing one or more response signals at a plurality of angles.

摘要： A drive circuit and method of controlling a quantum well modulator are disclosed. The drive circuit can be disposed in an optical transceiver having a quantum well modulator configured to retro-modulate an incoming optical signal. The drive circuit can include separate modulating and bias voltage sources. A level of the modulating voltage and the bias voltage can be determined based on an ambient temperature of the optical transceiver and can be adjusted to compensate for variations in the optical performance of the quantum well modulator. The quantum well modulator can be controlled in intervals. The modulating voltage can be applied to the quantum well modulator during a first interval. A current associated with the modulating voltage can be returned to the modulation voltage source during a second interval. A timing of the first and second intervals can be based on electrical properties of the quantum well modulator.

Embodiments include reading contactless data from a contactless device and associating it with information received from another source on the device. For example, associating a primary account number (PAN) and/or other information received from a contactless payment card's contactless interface with a PAN obtained from a magnetic stripe of the contactless payment card. The information can then be further associated with one or more products and/or a transit user account.

摘要： A system for achieving multi-axis angular alignment of devices includes a monolithic mount. The mount includes three sections arranged along a longitudinal axis. The first two sections are connected by two flexures that constrain the second section to rotate in relation to the first section in a first rotational degree of freedom. The second and third sections are connected by flexures that constrain the third section to rotate in relation to the second section in a second rotational degree of freedom. The first and second rotational degrees of freedom are different. Actuating screws contact bearing surfaces on the mount to actuate the rotations.

摘要： A laser safety device and method of protecting against harmful levels of radiation. The device includes a housing with first and second apertures. A photodetector generates a first signal corresponding to a level of radiation entering the housing through the first aperture. A control circuit receives the first signal and generates a drive signal based upon the level of the radiation. A reflector array which can include micro-electro-mechanical mirrors receives the drive signal and diverts a first part of the radiation away from an incident path extending from the first aperture to the second aperture. The reflector array allows a second part of the radiation to continue along the incident path at a safe level towards the second aperture. Optionally, the reflector array blocks the incident path so that substantially no radiation passes to the second aperture if unsafe levels are detected.

摘要： A system, method, and optical communication device are disclosed. The system can include a plurality of optically coupled nodes forming an optical communication network. Each node may include an array of pixel elements, each pixel element having an optical detector and an active optical source. The pixel array may be disposed in a backplane of a lens that is configured to map incoming optical signals to pixel locations in the backplane according to their respective angles of incidence and to minimize a deviation at each pixel location between incoming optical signals arriving at the optical detector and emissions from the optical source. The node may include a processor and memory. The processor can register senders in the optical network at locations in the pixel array and can generate routing information by which to route communications from the registered senders to other pixel elements for transmission to their respective destinations.
