摘要:
A mobile device includes an inertial navigation system (INS) to measure inertial quantities associated with movement of the device, and estimate a kinematic state associated with the movement based on the measured inertial quantities. The device includes a light receiver to record light beams originating from lights at respective image positions in a sequence of images. The device photogrammetrically determines its position relative to the originating lights based on predetermined real-world positions and corresponding image positions of the lights. The device corrects the estimated kinematic state based on the photogrammetrically determined position, to produce a corrected estimated kinematic state.
摘要:
A device, system, and method are presented for detecting motion. The system may include the device and a first transmitter and a second transmitter configured to transmit a first set of wireless signals and a second set of wireless signals, respectively. The device may have a receiver configured to receive the first and second set of wireless signals, and may further include a processing unit that determines a first value and a second value indicative of fading attenuations experienced by the first set of wireless signals and the second set of wireless signals, respectively. The processing unit may further determine whether the first and second values are each consistent with motion of an object in proximity to the device. The processing unit may cause the device to output an indication of presence of the object if both values are consistent with motion of the object in proximity to the device.
摘要:
This document discloses one or more systems, apparatuses, methods, etc. for detecting a region (e.g., sub-meter) of interest (ROI) using radio signals. In an implementation, during training stage, multiple channel fading profile samples within a user defined ROI are received and stored in a portable device. During detecting stage, the portable device may implement a sub-meter ROI detection algorithm to perform the detection.

摘要:
Embodiments of a multi-radio communication device and method for enabling coexistence between a Bluetooth transceiver and a broadband wireless access network (BWAN) transceiver are generally described herein. In some embodiments, the BWAN transceiver is configured to transmit a reservation request to a BWAN base station to reserve an amount of time during which no uplink transmissions are scheduled. The reservation request is configured to allow the Bluetooth transceiver to receive packets from a Bluetooth device without interference from transmissions by the BWAN transceiver.
摘要:
In a multi-radio platform that operates in two networks, both the announced beacon intervals and the actual beacon intervals in one network may be periodically increased and decreased in defined amounts so that the beacons will not overlap scheduled communications with the other network. The determination of how much and how often to adjust these beacon intervals may be based, at least partially, on the minimum increments in which the beacons intervals are permitted to be adjusted, and on the scheduled communications intervals of the other network.
摘要:
A first radio in a wireless network may request a transmit opportunity (TXOP) of a certain duration, with the duration being based a likelihood that a TXOP of that duration would cause interference with a co-located second radio. The duration may be dynamically adjusted based on the likelihood of such interference.

Embodiments of systems and methods for time domain multiplexing solutions for in-device coexistence are generally described herein. Other embodiments may be described and claimed.
摘要:
Methods and systems to implement a physical device to differentiate amongst multiple virtual machines (VM) of a computer system. The device may include a wireless network interface controller. VM differentiation may be performed with respect to configuration controls and/or data traffic. VM differentiation may be performed based on VM-specific identifiers (VM IDs). VM IDs may be identified within host application programming interface (API) headers of incoming configuration controls and data packets, and/or may be looked-up based on VM-specific MAC addresses associated with data packets. VM IDs may be inserted in API headers of outgoing controls and/or data packets to permit a host computer system to forward the controls and/or packets to appropriate VMs. VM IDs may be used look-up VM-specific configuration parameters and connection information to reconfigure the physical device on a per VM basis. VM IDs may be used look-up VM-specific security information with which to process data packets.
