Abstract: Compressing and restoring data using a multi-level autoencoder and a correlation network. The multi-level autoencoder compresses (in the encoder section) and decompresses (in the decoder section) data streams, and a separate correlation network trained on groups of input data sets restores lost data by leveraging correlations between the data sets.

Abstract: A system and method for compressing and restoring data utilizing a variational autoencoder to enable homomorphic compression techniques is disclosed. Input data is compressed into a latent space using an encoder network of a variational autoencoder. Homomorphic operations are performed on the compressed data in the latent space. The latent space compressed data is decompressed using a decoder network of the variational autoencoder. The homomorphic operations can enable performing operations while the data is in a compressed form, and preserving results of those operations while the data is in a decompressed form.

Abstract: Artificial intelligence (AI) layer-based process extraction for robotic process automation (RPA) is disclosed. Data collected by RPA robots and/or other sources may be analyzed to identify patterns that can be used to suggest or automatically generate RPA workflows. These AI layers may be used to recognize patterns of user or business system processes contained therein. Each AI layer may “sense” different characteristics in the data and be used individually or in concert with other AI layers to suggest RPA workflows.

Abstract: A device includes a phase detector circuit, a charge pump circuit, a sample and hold circuit, a comparator, and a controller. The phase detector circuit detects a clock skew between a reference signal and an input signal. The charge pump circuit translates the clock skew into a voltage. A sample and hold circuit samples the voltage, at a first time, and maintain the sampled voltage until a second time. The comparator (i) detects a loop gain associated with the input signal based on the sampled voltage and the voltage at the second time and (ii) outputs a loop gain signal for adjustment of the input signal. The controller is coupled to the phase detector, the comparator, and the sample and hold circuit. The controller generates a plurality of control signals for automatically controlling operation of the phase detector, the comparator, and the sample and hold circuit.

Abstract: Methods and devices for coding point clouds using direct coding mode to code coordinates of a point within a sub-volume associated with a current node instead of a pattern of occupancy for child nodes. When direct coding is applied to two or more points in the sub-volume, the points are ordered based on one of their respective coordinate values in binary and pairwise coding of those coordinate values is carried out on a bit-by-bit basis starting from the most significant bit position. For example, the coordinate values relate to a direction in the Cartesian coordinate system, the location of the first point is represented by an x-direction coordinate value, a y-direction coordinate value and a z-direction coordinate value. The pairwise coding includes coding whether the bits are the same and, if so, coding the bit value.

Abstract: An electrically conductive material configured having at least one opening of various unlimited geometries extending through its thickness is provided. The opening is designed to modify eddy currents that form within the surface of the material from interaction with magnetic fields that allow for wireless energy transfer therethrough. The opening may be configured as a cut-out, a slit or combination thereof that extends through the thickness of the electrically conductive material. The electrically conductive material is configured with the cut-out and/or slit pattern positioned adjacent to an antenna configured to receive or transmit electrical energy wirelessly through near-field magnetic coupling (NFMC). A magnetic field shielding material, such as a ferrite, may also be positioned adjacent to the antenna. Such magnetic shielding materials may be used to strategically block eddy currents from electrical components and circuitry located within a device.

Abstract: A system and method for event-driven data communication using codebooks with protocol adaption. The system initiates with a request for propagation information from an application to a first transaction manager. The first transaction manager configures a packet describing its location, potentially containing one or more protocol appendices, or encoded data using a codebook. This packet is provided to the application for transmission to another application with a second transaction manager. Upon receiving a protocol request from the second transaction manager, the first transaction manager communicates using a selected protocol decoded from the protocol appendix. If the selected protocol is supported, the transaction proceeds, completing successfully. This system enables transparent encoding, negotiation, and selection of communication protocols, allowing efficient transactions between different transaction managers.

Abstract: An interleaved analog-to-digital conversion (ADC) system may have timing errors in a time domain that is corrected using phase compensation in a phase domain. The ADC system may include sub-ADCs, each receiving a clock signal, which is associated with a representation of a timing skew value, reflecting an undesired timing error. A mixer may have sub-mixers, each receiving a sub-ADC output signal and a compensated numerically controlled oscillator (NCO) value. A combiner may combine the sub-mixer output signals. A decimator may decimate the output of the combiner. Each timing skew value is in a time domain. A compensated NCO value is determined using a respective phase skew value. Each phase skew value is an offset value in phase and is not a value in time. Each phase skew value in a phase domain compensates the respective timing skew value in a time domain. Multiple ADC systems and methods are described.

Abstract: Techniques are provided for compacting indirect blocks. For example, an object is represented as a structure including data blocks within which data of the object is stored and indirect blocks including block numbers of where the data blocks are located in storage. Block numbers within a set of indirect blocks are compacted into a compacted indirect block including a base block number, a count of additional block numbers after the base block number in the compacted indirect block, and a pattern of the block numbers in the compacted indirect block. The compacted indirect block is stored into memory for processing access operations to the object. Storing compacted indirect blocks into memory allows for more block numbers to be stored within memory.

Abstract: A system and method learning-based lossless data compression. The system and method proposed allow for fast and efficient lossless data compression of a large variety of data types. The system and method have a variety of real-world applications, including deep learning solutions for telemetry, tracking, and command subsystems for satellites. Satellites and their control centers are incredibly spaced apart which makes data compression an extremely important process to transmit large sets of information in a low-latency, high-efficiency environment. The proposed system and method utilize probability prediction driven arithmetic coding which provides faster encoding times and higher compression ratios when paired with a long short-term memory system for data compression.

Abstract: The disclosure provides a data acquisition device. The data acquisition device includes a sensor that detects a physical quantity as analog data; a digital storage circuit that stores the physical quantity as digital data; a difference circuit that calculates a difference between a previous value of the physical quantity stored in the digital storage circuit and a current value of the physical quantity detected as analog data; and a comparison circuit that compares the difference with a predetermined threshold value; and a control unit. The control unit stores a value calculated by adding or subtracting a predetermined change amount to a previous value of the physical quantity stored in the digital storage circuit as the current value, when the difference exceeds or falls below the threshold value. Since the physical quantity is updated without executing A/D conversion, a decrease in the sampling frequency is suppressed.
