    • 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.

    • A method and system for beamforming a multi-element array using time delays is provided. The array includes transmit array elements and receive array elements. Each of the array elements includes a processor. Modulation and demodulation functions are performed at the processors of each array element. The modulation and demodulation functions utilize receive time offsets and phase shifts, and transmit time offsets and phase shifts, respectively. The receive time offsets and phase shifts, and the transmit time offsets and phase shifts are determined by a central processing unit in order to beam form received signals and transmitted signals, respectively. The array elements are arranged in a daisy chain fashion in order to facilitate communication of control parameters, communication of bits to be transmitted and distributed combining of demodulated baseband samples from one array element to another and communicating the combined samples to the central processing unit.

    • Techniques are disclosed for creating optical systems and assemblies that provide increased field of view (FOV) for light detection by coupling a flip-chip light sensor directly to a condenser lens. According to certain embodiments of the invention, an optical assembly can include a condenser lens with a substantially flat surface optically contacted with a substantially flat surface of a substrate of a flip-chip light sensor. The thickness of the substrate is such that the active area of the light sensor is disposed on a focal plane of the optical system. This enables accurate light detection and increased FOV over conventional techniques.
