Abstract: Disclosed are techniques for wireless positioning. In an aspect, a wireless device receives one or more radio frequency (RF) signals from a transmitter device, displays a first arrow and a second arrow on a user interface of the wireless device, a direction of the first arrow representing a first angle-of-arrival (AoA) estimate of the one or more RF signals, and a direction of the second arrow representing a mirror AoA estimate of the first AoA estimate, and displays one or more notifications on the user interface instructing a user of the wireless device to move the wireless device until the direction of the first arrow is aligned with the direction of the second arrow.

Abstract: This disclosure provides methods, devices and systems for reducing power consumption in neighbor awareness networking (NAN) devices. Some implementations more specifically relate to dynamically adjusting a NAN device link (NDL) schedule to reduce the idle duration of a NAN data interface (NDI). The NDL schedule identifies a number of NAN slots, per discovery window (DW) interval, during which an NDL is available for data communications between NAN devices. In some aspects, a NAN device may measure congestion on the wireless channel during each NAN slot within a DW interval and may dynamically update the NDL schedule based on the measured congestion. In some other aspects, a NAN device may measure throughput on the NDL during each NAN slot within a DW interval and may dynamically update the NDL schedule based on the measured throughput.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a first station (STA) may receive a first packet from a second STA at a first time-of-arrival of the first packet. The first STA may activate a strobe signal to store first sensor data at the first time-of-arrival, wherein the first sensor data corresponds to a sensor output of one or more sensors of the first STA at the first time-of-arrival, wherein the one or more sensors include an accelerometer, a gyroscope, a magnetometer, or any combination thereof.

Abstract: This disclosure provides methods, devices, and systems for minimizing ranging errors resulting from clock drift and/or frequency offsets between wireless communication devices such as a responder device and an initiator device. In various implementations, the responder device receives a request for a ranging operation from the initiator device. The responder device determines whether its temperature exceeds a threshold. When the responder device's temperature exceeds the threshold, the responder device determines a time period after which the responder device's temperature is expected to decrease below the threshold. The responder device transmits a response frame indicating the responder device's temperature and the determined time period. In some instances, the determination that the responder device's temperature exceeds the threshold indicates that ranging errors resulting from clock drift and/or frequency offsets between the responder device and the initiator device are greater than an amount.

Abstract: A break recommendation method, system, and non-transitory computer readable medium, include detecting a deviation between a current cognitive state of the user and a past cognitive state of the user during a predetermined amount of time for a document type based on a change in an eye gaze movement and a facial and emotional expression and recommending that the user takes a break from viewing the document for a predetermined amount of time based on the deviation being greater than a predetermined threshold value, where the deviation is related to the user viewing the document and the document type of the document.

Abstract: Methods, systems, and devices for wireless communications are described. Wireless stations (STAs) may be within the coverage areas of several of access points (APs). In such cases, STAs may detect some set of candidate APs for possible connection, and the STAs may perform some selection procedure to select an AP for connection. For example, a STA may score or rank available APs (e.g., APs within the set of candidate APs), and the STA may sort the candidate APs into different bins (e.g., categories) based on their respective scores (e.g., based on each AP's candidate score). Each bin may thus include one or more APs associated with some scoring range. A STA may then randomly (e.g., or pseudo-randomly) select an AP from the bin associated with a highest range of candidate scores, and the STA may connect to the selected AP.

Abstract: A method of polishing includes bringing a metal layer of a substrate into contact with a polishing pad, generating relative motion between the substrate and the polishing pad, and while the metal layer is in contact with the polishing pad and the substrate is moving relative to the polishing pad, alternating between supplying a first polishing liquid and a second polishing liquid to an interface between the metal layer. The first polishing liquid is abrasive-free and includes an oxidizer, and the second polishing liquid includes abrasive particles and a complexing compound to complex with ions of the metal of the metal layer.

Abstract: The present disclosure describes a method and an apparatus for techniques used for wireless local area network (WLAN) scanning in coexistence scenarios. For example, a method for is provided for WLAN scanning in which a scan of a WLAN is initiated at a wireless device configured to share an antenna for WLAN operations and Bluetooth (BT) operations while a voice call is in progress over the WLAN and packets from the voice call are routed between the wireless device and a BT device. A clear-to-send-to-self (CTS2Self) packet may be broadcast to reserve a communication channel for the wireless device after the scan is initiated. Moreover, a probe request may be broadcast after the broadcast of the CTS2Self packet, where the CTS2Self packet and the probe request are broadcast during a same WLAN interval of the WLAN operations and while the voice call is in progress over the WLAN.

Abstract: After determining that a P2P discovery process is to commence, at least a portion of the P2P discovery process is delayed to permit communication via a non-P2P communication link, and/or at least a portion of the P2P discovery process is not performed to permit communication via the non-P2P communication link. Communications are performed via the non-P2P communication link during a time period that, prior to the act of delaying the P2P discovery process and/or deciding not to perform the P2P discovery process, would have been allocated for the P2P discovery process.
