Abstract: A modified back propagation (MBP) method designed to substantially enhance the computational speed of near-field microwave imaging and millimeter wave imaging. This method leverages two key factors to boost efficiency. Firstly, it employs path dimension reduction to diminish computational workload, accomplished by employing approximate path ranges. Rather than utilizing numerous highly precise path ranges to calculate phase shifts, this approach selects an appropriate range unit for approximate ranges, resulting in a significant reduction in computational workload with minimal impact on image quality. Secondly, it harnesses the power of an inverse fast Fourier transform along the frequency (wavenumber) dimension, representing frequencies as a minimum frequency plus increments. Through the combination of these two enhancements, the MBP method becomes applicable to real-time imaging systems, including but not limited to body security screening systems.

Abstract: The present disclosure describes a non-welded leaf spring battery cell connector which allows for unrestricted outgassing during Lithium-Ion thermal runaway. The connector also has a low-resistance electrical connection surface for applications with rough, uneven contact surfaces such as those on refurbished Lithium-Ion battery cells. The connector is compatible with both protected and unprotected Lithium-Ion cells, as it allows for up to about 5 mm of vertical travel to support varying battery cell lengths caused by battery protection circuits. The leaf spring connector for Lithium-Ion battery cells is made of a conductive sheet of metal, cut and folded into a leaf-spring connector for a removable, non-welded battery cell. The leaf spring connector has one or more areas of material removed, as to not block the flow of caustic gasses during emergency outgassing.

Abstract: Techniques and apparatuses are described for resource block-level index modulation. In aspects, a wireless transmitter modulates a first portion of data for a wireless receiver to provide modulation symbols that correspond to the first portion of the data. The wireless transmitter also selects, based on a value of a second portion of the data, respective index locations for one or more resource blocks by which to transmit the modulation symbols. The wireless transmitter then transmits the modulation symbols to the wireless receiver using the one or more resource blocks having the respective index locations to convey the first portion of the data and the second portion of the data to the wireless receiver. By so doing, the wireless transmitter conveys the second portion of the data without using additional time-frequency resources of a communication channel, which can be useful when concurrently transmitting small amounts of data to many wireless receivers.
