Abstract: A position of a user equipment (UE) may be determined using downlink based solutions (e.g. OTDOA), uplink based solutions (e.g. UTDOA), or combined downlink and uplink based solutions (e.g. RTT). The serving gNBs may request neighboring gNBs to produce downlink reference signal transmissions to a target UE and/or measure uplink reference signal transmissions from the target UE. The serving gNB may receive the uplink reference signal measurements from neighboring gNBs and obtain an own uplink reference signal measurement and forward to the UE or another network entity all the uplink reference signal measurements. The UE may use the uplink reference signal measurements, along with the UE's own downlink reference signal measurements to determine RTTs. The serving gNBs or another entity may keep the uplink reference signal measurements and may determine RTTs after receiving the downlink reference signal measurements from the UE.

Removal of the manually applied force may lock the distal tip portion in its then-current configuration. The non-motorized and non-ratcheting actuation mechanism may include a clutch mechanism actuatable in response to an electrical signal generated in response to sensing a user-applied force to the actuating mechanism by a strain gauge.

Abstract: A method of enabling a user of a computing device to provide input via a viewport displayed on a display monitor. The viewport is displayed over a first region of the graphic user interface (GUI), and a second region of the GUI is displayed within the viewport. When the user positions the system pointing indicium at the first region of the graphic user interface, the system pointing indicium is placed into the second GUI region, while a separate viewpoint pointing indicium is displayed over the viewport. When a user provides an input, the input is applied at the current position coordinates of the system pointing indicium.

Abstract: Techniques described herein are directed to improving the positioning of a target user equipment (UE) using an enhanced repeater disposed in a wireless network. In some embodiments, the enhanced repeater may include logically distinct user equipment (UE) functionality and distributed unit (DU) functionality. The UE functionality may enable setup with other entities of the network, e.g., an upstream location management function (LMF), such that the enhanced repeater is recognized as capable of positioning. The DU functionality may enable generation of downlink positioning signals (e.g., DL-PRS) at the enhanced repeater so as to obviate relaying of DL-PRS generated elsewhere in the network. The enhanced repeater may perform uplink measurements based on uplink positioning signals receive from the target UE, and report the uplink measurements to the LMF, enabling the LMF to calculate the position of the UE with fewer errors than if the uplink positioning signals were simply relayed.

Abstract: A method for ascertaining at least one eye state of at least one person situated in a defined spatial region. At least one light beam is directed, in a scanning manner, into the defined spatial region using a light source of a scanning laser feedback interferometry sensor. The defined spatial region has, in the horizontal direction, at least the dimension of a width of a head of the person. A modulation of the power of the light source of the laser feedback interferometry sensor is measured as a function of at least one light beam reflected back by at least one eye of the person situated in the defined spatial region. The at least one eye state of the at least one person situated in the defined spatial region is ascertained as a function of the modulation of the power of the light source, using a processing unit.
