Abstract: A solar cell for a solar cell array with one or more grid on a surface thereof, wherein electrical connections are made to the grids in a plurality of locations positioned around the solar cell; and the electrical connections extend to one or more conductors located under the solar cell. The conductors located under the solar cell are buried within a substrate, and each of the conductors comprises a low resistance conducting path that distributes current from the solar cell. The conductors are loops, U-shaped, or have only up or down pathways. The solar cell comprises a full cell that has four cropped corners and the locations are in the cropped corners.

Abstract: Systems and methods for performing logical semantic sentence comparisons and sentence-based searches. Training is performed by running an NLP pipeline on unstructured text comprising sentences and creating sentence matrix representations on the unstructured text; storing the matrix representations in an indexed database; combining the stored matrix representations; running an SVD on the combined matrix; storing the SVD components in the indexed database; reiterating through the output of the NLP pipeline the sentences of the unstructured training text to form a low-dimensional matrix conversion for each sentence for storage in the database based on the calculated SVD components. Subsequent query statements are run through the same process based and converted into low-dimensional matrix representations using the SVD components from training; the low-dimensionality query matrix is compared to the stored low-dimensional matrices to determine the closest relevant documents, that are returned to the user.

Abstract: A unidirectional sampling mixer utilizes a stepped phase modulation to shift the frequency of an input signal. An RF input signal is supplied to an RF input switch from an RF input port. An ordered set of phase shift values to be applied to the RF input signal and a set of times each element of which correspond to a time at which a phase shift value is be applied to the RF signal are determined. For each phase shift value within the ordered set of phase shift values, a controller controls the RF input switch to select an input of a phase shifting device and controls an RF output switch to select an output of the phasing shifting device. The input of the phase shifting device and the output of the phase shifting device are selected to apply the phase shift value at its corresponding time to the RF input signal. A frequency shifted signal is supplied to an RF output port from an output of the RF output switch.

Abstract: A system and method for spreading and de-spreading a signal at an antenna. A Direct Spatial Antenna Modulation (DSAM) system makes use of the spatial characteristics of a radiating antenna structure to directly alter a signal transmitted or received by the radiating structure. When used for transmitting data, a data stream maps a signal to different spatial points of excitation in the antenna structure, where each chosen configuration has different radiating characteristics including phase, amplitude, and polarization, which can be used to represent data symbols. A code spreading sequence is applied to switch the output of the DSAM antenna to spatial points in the antenna to spread an input signal. The code spreading sequence is applied to an antenna to de-spread a previously spread signal. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this Abstract.

Abstract: A Direct Spatial Antenna Modulation (DSAM) antenna structure makes use of the instantaneous electromagnetic field state of a radiating antenna structure to achieve direct modulation of a transmitted signal within the antenna. In contrast to existing amplitude and phase-only based digital modulation techniques, this innovative technique utilizes an inherent spatial modulation component, mapping data spatially to different locations in the antenna structure, where each location has different transmitting and receiving properties. This spatial component of the modulation can enable, for example, a unique increase in data transmission speed in a fixed spectral bandwidth with no increase in bit error rate over current phase and amplitude only modulation techniques. Additionally, the DSAM antenna structure affords important benefits in reduced hardware complexity, reduced supply current consumption, and relaxed amplifier linearity requirements.
