摘要： Systems and methods for providing self-healing integrated circuits. The method is characterized in that the behavior of a circuit or a device in response to an input signal is observed. One or more operational parameters or characteristics of the circuit or the device are derived. A corrective action to bring the operational parameters or characteristics of the circuit or device within a desired range is deduced, if needed. The corrective action can be the application of a correction signal or a modification of one or more parameters or characteristics of an element in the circuit. The calculated corrective action, if needed, is applied to bring the operational parameters or characteristics of the circuit or device within the desired range. Optionally, the operational parameters or characteristics of the circuit or the device after the correction is effectuated can be checked.

摘要： A radiator is formed by forming a multitude of slot antennas adjacent one another such that the spacing between each pair of adjacent slot antennas is smaller than the wavelength of the signal being transmitted or received by the radiator. The radiator achieves high efficiency by reducing the excitation of substrate modes, and further achieves high output power radiation by combining power of multiple CMOS power amplifiers integrated in the radiator structure. Impedance matching to low-voltage CMOS power amplifiers is achieved through lowering the impedance at the radiator ports. Each output power stage may be implemented as a combination of several smaller output power stages operating in parallel, thereby allowing the combination to utilize an effective output device size commensurate with the impedance of the radiator.

摘要： A space-based solar power station, a power generating satellite module and/or a method for collecting solar radiation and transmitting power generated using electrical current produced therefrom is provided. Power transmitters can be coordinated as a phased array and the power generated by the phased array is transmitted to one or more power receivers to achieve remote wireless power generation and delivery. In many embodiments, a reference signal is distributed within the space-based solar power station to coordinate the phased array. In several embodiments, determinations of the relative locations of the antennas in the array are utilized to evaluate the phase shift and/or amplitude modulation to apply the reference signal at each power transmitter.
