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.

A magnetic resonance technology is used to implement front and back proximity sensing capability for wireless devices such as a laptap device. For example, a high quality (Q) factor coil antenna may be embedded in a display, such as a liquid crystal display, of a first laptap device to detect other wireless devices (e.g., a second laptap) that are within coupling distance of the first laptap device. In this example, the second laptap device induces a sine wave signal to the first laptap device if the second laptap device is physically located at backside of the first laptap device. Otherwise, the second laptap device may induce a cosine wave signal to the first laptap device if the second laptap device is physically located at the front side of the first laptap device.

The RSSIs corresponding to wireless APs within an interior of a structure and represented in the location database.
摘要:
A location of a wireless device relative to a vehicle is determined using received data. Data may be received from the vehicle sensors. Data may also be received from the wireless device sensors of a wireless device. The presence of one or more persons may be determined using received data. A user-to-wireless device association may be detected based, at least in part, upon the presence of one or more persons in the vehicle and the location of the wireless device relative to the vehicle.

After receiving an indication that a co-located central point is receiving co-location interference, a scheduling algorithm may be initiated. The scheduling may include allocating equal number of central points within each WiMAX frame. Each central point is allocated into a minimum number of frames subject to WiMAX capacity constraints.

Embodiments may comprise logic such as hardware and/or code to adaptively control the transmission power for a wireless channel. In many embodiments, adaptively controlling the transmission power may reduce or, in some embodiments, minimize interference between the wireless display (WiDi) transmissions and other transmissions such as multimedia content streaming over another wireless channel to the notebook via a second generation (2G) channel, third generation (3G) channel, or a future long term evolution (LTE) channel.

摘要:
Methods and systems to permit multiple virtual machines (VMs) to separately configure and access a physical resource, substantially outside of a virtual machine monitor (VMM) that hosts the VMs. Each of a plurality of virtual machines (VMs) may access and configure the physical device through corresponding instances of a device driver that exposes controllable functions of the physical device within the VMs. VM-specific configuration parameters and connection information may be maintained for each of the VMs, outside of a VMM, to reconfigure or virtualize the physical device for each of the VMs with the corresponding VM-specific configuration parameters and connection information. Physical device virtualization augmentation features may be implemented within a combination of a physical device controller and a host device driver that executes outside of the VM.

A collocated radio coexistence method is disclosed. The method operates in the frequency domain to protect WiMAX downlink traffic from narrow band interference (e.g. harmonics) caused by other collocated radios, such as GSM 800 MHz, operating simultaneously with an 802.16-capable (WiMAX) radio in a multiple radio coexistence platform (MRP).
摘要:
In general, in one aspect, the disclosure describes a method that includes selecting an offset between start of communications of a first radio in a multi-radio platform (MRP) and start of communications of a second radio in the MRP. Synchronizing clocks of the first radio and the second radio to maintain the offset. Determining safe zones within the communications of the second radio based on configuration of the first radio and the second radio and the selected offset. The safe zones are locations that minimize conflicts between receiving operations of the first radio that are at fixed locations and transmitting operations of the second radio and transmitting operations of the first radio that are at fixed locations and receiving operations of the second radio.
