Abstract: Ultra-wideband (UWB) tags can be used as part of a high-resolution motion capture system that may not require a cost or a complexity that is typically associated with visually based motion capture systems. The UWB based motion capture uses a bundle of UWB tags, which in a possible implementation, can be affixed to body parts of a user to sense motion of the body parts. The absolute positions of each UWB tag can then be determined by reconstructing a skeletal topology from a Euclidean distance matrix based on inter-tag ranging measurements using handshake signals of a UWB protocol.

Abstract: Composite lithium ion batteries having an anode with an anode collector and a composite anode material, a cathode with a cathode collector and a composite cathode material, a separator positioned between the anode and the cathode, and an electrolyte in contact with the anode and the cathode. Advantages of the composite lithium ion batteries include lower DC impedance, faster charging times, more reserve capacity between 3.0V and 2.5V, and an increased volumetric energy density relative to lithium ion batteries that do not include the described composite material electrodes.

Abstract: A computer-implemented method includes receiving a two-dimensional (2-D) side view face image of a person, identifying a bounded portion or area of the 2-D side view face image of the person as an ear region-of-interest (ROI) area showing at least a portion of an ear of the person, and processing the identified ear ROI area of the 2-D side view face image, pixel-by-pixel, through a trained fully convolutional neural network model (FCNN model) to predict a 2-D ear saddle point (ESP) location for the ear shown in the ear ROI area. The FCNN model has an image segmentation architecture.

Abstract: A system for passive alignment of fibers to an interface of a photonic integrated circuit (PIC) includes an input frame, an actuator, and an output frame. The actuator arranged to apply force along a force axis to the input frame. The output frame including a tip for picking up a plate and transferring the force thereto, the output frame being connected to the input frame such that the output frame may tilt relative to the input frame and the output frame is elastically biased relative to the input frame into a position wherein the tip is aligned on the force axis.

Abstract: The present disclosure describes various aspects of complementary 2(N)-bit redundancy for single event upset (SEU) prevention. In some aspects, an integrated circuit (104) includes a data storage element (206) to store a data value, another data storage element (202) to store a complementary data value, a multi-bit data storage element (e.g., a 2-bit storage element, (204)) to store both the data value and the complementary data value, and voting logic (124) that may enable a complementary data storage scheme with inter-circuit redundancy to prevent SEU. Additionally, the voting logic of the integrated circuit may enable detection and correction of data value errors and/or enable programming of voting logic criteria, which may be implemented dynamically based on a type of SEU failures that are detected or corrected.

Abstract: A micro light-emitting diode, micro-LED, is configured to provide increased light-extraction. The micro-LED (300) according to the present disclosure has a lateral dimension less than 20 micrometres and comprises: a light-emitting layer (106), an output facet (308), an optical interface (via a mirror 114) parallel to the light-emitting layer, and a non-vertical sidewall (102) forming an angle with respect to a normal of the light-emitting layer. The layer (106) emits light (310) comprising a first light (312) in a first trajectory that escapes the micro-LED through the output facet (308) without reflecting off the optical interface and a second light (314) in a second trajectory that reflects off the optical interface and the non-vertical sidewall (102) and escapes through the output facet. The disclosed micro-LEDs may further include one or more of: cavity effects, light guiding, total internal reflection at low-index layers, mirrors, and micro-optics.

Abstract: Implementations set forth herein relate to an automated assistant that can initialize execution of an assistant command associated with an interpretation that is predicted to be responsive to a user input, while simultaneously providing suggestions for alternative assistant command(s) associated with alternative interpretation(s) that is/are also predicted to be responsive to the user input. The alternative assistant command(s) that are suggested can be selectable such that, when selected, the automated assistant can pivot from executing the assistant command to initializing execution of the selected alternative assistant command(s). Further, the alternative assistant command(s) that are suggested can be partially fulfilled prior to any user selection thereof. Accordingly, implementations set forth herein can enable the automated assistant to quickly and efficiently pivot between assistant commands that are predicted to be responsive to the user input.

Abstract: A user equipment (UE) determines that a protocol data unit (PDU) session comprises an adaptable PDU session. The UE determines whether a current energy mode of the UE comprises an energy-saving mode. In response to determining that the current energy mode of the UE comprises the energy-saving mode, the UE establishes the adaptable PDU session in a non-always-on mode; and in response to determining that the current energy mode of the UE does not comprise the energy-saving mode, the UE establishes the adaptable PDU session in an always-on mode. Further, the UE can initially establish a mode of a plurality of adaptable PDU sessions as the non-always-on mode, when connecting to a certain type of network.

Abstract: A distributed unit (DU) of a distributed base station, where the distributed base station that includes the DU and a central unit (CU), can perform a method for managing early data transmission (EDT) with a user equipment (UE). The method includes: performing (1402), while a radio connection between the UE and the DU is not active, a random access procedure, including receiving, from the UE, an uplink message formatted in accordance with a protocol for controlling radio resources; sending (1404), to the CU, a DU-to-CU message including the uplink message; receiving (1406), from the CU, a CU-to-DU message when a validity of the uplink message has been verified; generating (1408) a contention resolution ID for the UE; and transmitting (1410), to the UE, the contention resolution ID for EDT without transitioning the UE to a connected state.
