Abstract: A method of estimating local oscillator leakage (LOL) for a radio frequency (RF) signal transmitter. The method comprises generating a transmitter wideband baseband signal (s(t)) with a direct current (DC) voltage element of the transmitter wideband baseband signal (s(t)) removed or blocked and an average of the transmitter wideband baseband signal (s(t)) set to zero. The method includes processing said transmitter wideband baseband signal (s(t)) to form a RF signal; processing the RF signal to obtain a receiver baseband signal (y(t)); and determining a magnitude of an average of the receiver baseband signal (y(t)) as comprising a magnitude of the transmitter DC offset.

Abstract: Described is a method and device for detecting a DTX state at a UCI receiver in a wireless communication system. The method comprises receiving a linear block encoded signal on an uplink at said UCI receiver and processing the received signal after resource element (RE) demapping to generate a soft bit sequence {right arrow over (s)}. The method includes selecting a plurality of bits in said generated soft bit sequence {right arrow over (s)} as comparison bits and comparing said selected comparison bits to corresponding bits in a reconstructed soft bit sequence {right arrow over (r)}. The reconstructed soft bit sequence {right arrow over (r)} is generated from a plurality of bits selected as reconstruction bits in said generated soft bit sequence {right arrow over (s)}. A comparison or correlation metric is determined between the comparison bits and the corresponding bits in the reconstructed soft bit sequence {right arrow over (r)}, and a determination is made of the occurrence of a DTX state by evaluating the determined comparison or correlation metric.

Abstract: Systems and methods in which a thermal conductive composite comprises a non-uniform heat absorption profile of a thermal reactive material are described. Thermal conductive composites herein may be utilized in thermal regulatory modules with a gradient structure configured to transfer heat energy away from an area near a heat source to an area with a relatively large latent heat absorbing capacity. Thermal conductive material may be provided in a frame structure having lower porosity in a first region more near a heat source and higher porosity in a second region more distant from the heat source. A thermal reactive material may be deposited so as to be disposed within the pores of the thermal conductive material frame structure wherein the density of the thermal reactive material in the first region of the thermal conductive composite is lower than that at the second region of the thermal conductive composite.

Abstract: Described is a method of determining a position of a mobile wireless device in a wireless communication network. The method comprises, for a plurality of clusters of transmission reception points (TRPs) associated with said mobile wireless device, measuring a parameter of first reference signals transmitted between said mobile wireless device and a single TRP from each cluster of TRPs. The method includes, based on the respective measured parameter of the first reference signals, selecting one cluster of TRPs from said plurality of clusters of TRPs. Position estimation information is determined from second reference signals transmitted between said mobile wireless device and a plurality of the TRPs comprising the selected cluster of TRPs. The determined position estimation information is used to determine a position for said mobile wireless device.

Abstract: Described is a method of identifying a short-circuit (SC) like event in a circuit breaker (CB). The method comprises sampling an incoming current to the CB to determine a maximum value of a slope of a curve of the incoming current. The method includes sampling the incoming current again before a level of the incoming current reaches a predetermined, preset, selected, or calculated SC threshold value THSC for the CB. The method involves determining from the sampled incoming current that a value of the slope of the incoming current has changed from its maximum slope value to a lower slope value to thereby determine that the incoming current is indicative of a SC like event and does not comprise a real SC event.

Abstract: Described is a method and device for detecting a DTX state at a UCI receiver in a wireless communication system. The method comprises receiving a linear block encoded signal on an uplink at said UCI receiver and processing the received signal after resource element (RE) demapping to generate a soft bit sequence s. The method includes selecting a plurality of bits in said generated soft bit sequence s as comparison bits and comparing said selected comparison bits to corresponding bits in a reconstructed soft bit sequence r. The reconstructed soft bit sequence r is generated from a plurality of bits selected as reconstruction bits in said generated soft bit sequence s. A comparison or correlation metric is determined between the comparison bits and the corresponding bits in the reconstructed soft bit sequence r, and a determination is made of the occurrence of a DTX state by evaluating the determined comparison or correlation metric.

Abstract: Systems and methods which provide data exchange using a distributed ledger, wherein data is exchanged off-chain and information for accessing the off-chain data is exchanged through the blockchain, are disclosed. Embodiments may provide a hybrid blockchain data exchange platform storing large amounts of data (e.g., IoT data) in a data server outside of the blockchain, wherein a data consumer may obtain data from the data server using a token obtained from the blockchain. Embodiments of a hybrid blockchain data exchange platform provide for accuracy and security of the data without requiring storage of the full contents of the data within the blockchain, and/or provide data exchange in which the irrefutability of the data exchanged is ensured.

Abstract: There is disclosed an apparatus for visually inspecting gemstones. The apparatus contains a first light source, a sample stage adapted to receive a gemstone thereon, and a rotating stage located below the sample stage. The rotating stage is adapted to rotate relative to the sample stage. Embodiments of the invention therefore provide a portable and automatic gemstone inspecting apparatus that provides multiple inspection methods centrally without the need to use other external devices.

Abstract: Described is a method of decoding a physical sidelink control channel (PSCCH). The method comprises: for a PSCCH candidate in a resource grid, processing a received demodulation reference signal (DMRS) in a subframe of said resource grid associated with said PSCCH candidate to determine one or more potential PSCCHs for decoding, each of said one or more potential PSCCHs being identified by resource block (RB) position in the resource grid and a corresponding DMRS cyclic shift (ncs) value. The foregoing step is repeated for at least one other DMRS in said subframe to determine one or more potential PSCCHs for said at least one other DMRS. Then, a subset L of PSCCHs is selected from said potential PSCCHs whereby said selected subset L of PSCCHs together with their corresponding DMRS cyclic shift (ncs) values are made available for use in a decoding process for the received channel signal.

Abstract: Systems and methods providing adaptive path planning techniques utilizing localized learning with global planning are described. The adaptive path planning of embodiments provides global guidance and performs local planning based on localized learning, wherein the global guidance provides a planned path through the dynamic environment from a start location to a selected destination while the local planning provides for dynamic interaction within the environment in reaching the destination, such as in response to obstacles entering the planned path. Global guidance may combine an initial global path with history information for providing a global path configured to avoid points of frequent traffic conflicts. Local planning may utilize localized deep reinforcement learning to direct interactions of an automated vehicle traversing the global path in a dynamic environment, such as in response to obstacles entering the global path. Sequential localized maps may be generated for deep learning models utilized by localized training techniques.
