Abstract: A patch antenna system comprises a patch antenna and preferably two sets of strip-shaped parasitic elements arranged over the radiating edges of the patch antenna. The parasitic elements are spaced away from the patch antenna. Preferably, the material placed between the patch antenna and parasitic elements is selectively deposited to introduce an air gap between the elements and the antenna while also introducing mechanical support for the elements. This selective deposition of material also relaxes the requirements for high radio frequency (RF) performance, thereby reducing cost. One advantage of this solution is that it enables circular polarization to be achieved.

Abstract: A method and a system for implementing a mathematical algorithm in a neural architecture and transferring that neural architecture to an integrated circuit (IC) chip. The neural architecture has neurons that are capable of converting current to frequency, voltage to frequency, frequency to frequency and time to frequency. The neurons can have multi-sensor inputs (multiple synapses) for either scaling or inhibiting neuron outputs. The neural architecture-to-hardware conversion method is specifically tailored for neural architectures for image processing applications.

Abstract: This invention discloses a multispectral imaging system, DFPA (digital focal plane array), in the form of an integrated circuit of three structures each of which is implemented on a chip. The top structure consists of detectors capable of imaging in the visible to LWIR wavelengths. The middle structure of neuromorphic focal array contains ROI circuitry and inherent computing capabilities for digitization, convolution, background suppression, thresholding, and centroid determination of the ROIs. The bottom structure (dubbed common digital layer) is capable of additional image processing tasks and reconfiguring the neuromorphic focal array. In a simpler embodiment of the invention, the system only has the top two layers, with an external processor taking over the role of the common digital layer.
