Abstract: Performance improvement of an all-optical analog-to-digital converter (AOADC) addresses both RF and optical modeling of a leaky waveguide based optical spatial light modulator (SLM) using electro-optic (E-O) material. The E-O polymer provides improved sensitivity for SLM and achieves a broader bandwidth due to better velocity matching between RF and optical waves.

Abstract: A dynamic capacitive power transfer system for an elevator that can realize the real-time powering of the elevator when it is in the moving status. It includes a metal track along the building side as the power transmitter and a piece of metal at the elevator side as the power receiver. There is a gap between the transmitter and receiver, and up to kW power can be transferred wirelessly and efficiently to serve the air conditioner, lightning, and other electronic devices in the moving car. The steel wheels and ropes may be used to connect the moving car to the earth ground, which contributes to form the current returning loop. It eliminates the electric cables and the corresponding flexible cable carrier system for the linear movement.

Abstract: Low latency beamforming using phased antenna arrays is the key for practical deployment of envisioned millimeter wave (mmWave) Gbps mobile networks. This work aims towards reducing the overhead of the exhaustive sector-level sweep phase of the analog beamforming adopted in the IEEE 802.11ad standard. This system uses a reconfigurable antenna single RF chain in the sub-6 GHz new radio (NR) band to aid codebook-based beam selection in the mmWave band of the NR. The system exploits the congruence between the spatial propagation signatures of signals at both mmWave and sub-6 GHz frequencies to reduce the beam search space.

Abstract: The system uses natural language to paths of a transition diagram via answer set programming system and provides: an approach for mapping events described in natural language sources to a logical formalism; and integration of Natural Language Processing and constraint-based reasoning inspired by Reasoning about Actions and Change. The system further uses (a) a non-trivial variant of IR in which sources include sequences of events, and queries are made about the state of the world after such events; (b) the extension of techniques for representing dynamic domains to increase the flexibility of the reasoning processes in the presence of uncertainty; (c) a formalization of the IR task based on action languages; (d) an automated IR procedure based on Answer Set Programming (ASP).
Abstract: The present invention relates to a novel cathode employing a monoclinic sulfur phase that enables a single plateau lithium-sulfur reaction in, for example, a carbonate electrolyte system. The cathode is applicable to a variety of other types of anodes. Also disclosed are an electrode of a cell or battery and a battery including the cathode.
Abstract: A field-programmable analog array (FPAA) fabric includes a 6×6 matrix of configurable analog blocks (CABs). The implementation of programmable CABs eliminates the use of fixed analog subcircuits. A unique routing strategy is developed within the CAB units that supports both differential and single-ended mode circuit configurations. The bandwidth limitation due to the routing switches of each individual CAB unit is compensated for through the use of a switch-less routing network between CABs. Algorithms and methodologies facilitate rapid implementation of analog circuits on the FPAA. The proposed FPAA fabric provides high operating speeds as compared to existing FPAA topologies, while providing greater configuration in the CAB units as compared to switch-less FPAA. The FPAA core includes 498 programming switches and 14 global switchless interconnects, while occupying an area of 0.1 mm2 in a 65 nm CMOS process.

Abstract: Low phase noise signal generated in a small structure is required for communication and high-resolution imaging. A DBR based multi-mode laser is combined with mode-locking method to build frequency stabilized and tunable RF signal generator. The number of the output modes from each laser is adjusted using reflecting bandwidth of distributed Bragg reflector and electro-absorption (EA) modulator for amplitude control, while the phase section in integrated laser system provides frequency tuning. Mode-locking of 60 laser modes results in a highly frequency stable 10 GHz RF beat-notes with a calculated phase noise of ?150 dBc/Hz at 10 kHz offset frequency.
