Abstract: A quantum key distribution system may include a transceiver including a state randomizer to impart a random state transformation to one or more qubits of a generated faint pulse and a quantum bit encoder to reflect the faint pulse back to the transceiver with one or more encoded bits.

The transceiver may include three or more detectors to measure the return pulse at time-gated timeslots associated with possible paths of the return pulse. Reception of the faint pulse from the quantum bit encoder as the return pulse triggers a detector in a first known subset of the detectors, while reception of a faked-state pulse from a third party as the return pulse results in a non-zero probability of triggering of a detector in a second known subset of the detectors.

Abstract: Covalent organic frameworks (COFs) usually crystallize as insoluble powders and their processing for suitable devices has been thought to be limited. Here, it is demonstrated that COFs can be mechanically pressed into shaped objects having anisotropic ordering with preferred orientation between the hk0 and 00l crystallographic planes. Pellets prepared from bulk COF powders impregnated with LiClO4 displayed room temperature conductivity up to 0.26 mS cm?1 and stability up to 10.0 V (vs. Li+/Li0). This outcome portends use of COFs as solid-state electrolytes in batteries.

Abstract: The invention pertains to methods for monitoring the operational status of a home automation system through extrinsic visual and audible means. Initial training periods involve capturing image and audio data representative of nominal operation, which is then processed to identify operational indicators. Unsupervised machine learning models are trained with these indicators to construct a model of normalcy and identify expectation violations in the system's operational pattern. After meeting specific stopping criteria, real-time monitoring is initiated. When an expectation violation is detected, contrastive collages or sequences are generated comprising nominal and anomalous data. These are then transmitted to an end user, effectively conveying the context of the detected anomalies. Further features include providing deep links to smartphone applications for home automation configuration and the use of auditory scene analysis techniques.

Abstract: A system of sensors integrated into toys for monitoring free play activity of a human subject wherein patterns in play activity automatically are weighted into a pattern for identification of behavioral milestones, developmental progress and/or behavioral disorders. Specifically, accelerometers detect movement of toys which determine: (1) if the toy is being played with; and (2) the intensity in which the toy is moved. Pressure sensors detect the level and location in which a child may hold a toy. Synchronized with an audiovisual record of the play therapy session and a computer-generated avatar representation of the physical object, this data is integrated to find peak levels of behavior giving clinicians more efficient analytical tools.

Abstract: A method for pre-processing files that can improve file compression rates of existing general-purpose lossless file compression algorithms, particularly for files on which traditional algorithms perform poorly. The elementary cellular automata (CA) pre-processing technique involves finding an optimal CA state that can be used to transform an original file into a format (i.e., an intermediary file) that is more amenable to compression than the original file format. This technique is applicable to multiple file types and may be used to enhance multiple compression algorithms. Evaluation on generated files, as well as samples selected from online text repositories, finds that the CA pre-processing technique improves compression rates by up to 4% and shows promising results for assisting in compressing data that typically induce worst-case behavior in standard compression algorithms.

Abstract: A smart, human-centered technique that uses artificial intelligence and mixed reality to accelerate essential tasks of the inspectors such as defect measurement, condition assessment and data processing. For example, a bridge inspector can analyze some remote cracks located on a concrete pier, estimate their dimensional properties and perform condition assessment in real-time. The inspector can intervene in any step of the analysis/assessment and correct the operations of the artificial intelligence. Thereby, the inspector and the artificial intelligence will collaborate/communicate for improved visual inspection. This collective intelligence framework can be integrated in a mixed reality supported see-through headset or a hand-held device with the availability of sufficient hardware and sensors. Consequently, the methods reduce the inspection time and associated labor costs while ensuring reliable and objective infrastructure evaluation.
