Abstract: Aspects of the disclosure relate to computing technologies. In particular, aspects of the disclosure relate to mobile computing device technologies, such as systems, methods, apparatuses, and computer-readable media for improving orientation data. In one embodiment, techniques are described for filtering data associated with a sensor coupled to a computing device, by receiving a signal from the sensor, detecting a change in a variability of a first signal parameter from a plurality of signal parameters from the signal, and adjusting, based at least in part on the detected change in the variability of the first signal parameter, at least one filter parameter of a filter used to filter a second signal parameter from the signal.

Abstract: Embodiments of the present invention are directed toward providing refocusable image. Refocusable images are images that, after being captured, can be refocused, or adjusted to have a different focal length. The embodiments described herein can utilize a mobile user device, such as a smartphone, without the need for specialized hardware. A camera of the mobile device can be configured to take a series of images in succession over a short period of time in which the focal length of the camera is varied so that each image has a different focal length. An image stack is created by aligning the images, and images are processed to determine which image has the highest contrast (i.e., is in focus) for each region of the image stack. Embodiments can further include displaying a first image of the series of images.

Abstract: Aspects of the disclosure relate to computing technologies. In particular, aspects of the disclosure relate to mobile computing device technologies, such as systems, methods, apparatuses, and computer-readable media to improve the calibration data by taking into account the effects of change in temperature on motion sensors. For instance, different levels of error may be associated with a motion sensor at different temperature levels. In one implementation, the sensor measurement data associated with the various orientations at a temperature is used in determining the calibration data for that temperature.

Abstract: A mobile station determines its position using measured parameters of a wireless signal to improve a satellite positioning system (SPS) enhanced dead reckoning based position estimate. The mobile station uses SPS enhanced dead reckoning to estimate a current position. The mobile station receives wireless signals from a plurality of access points and determines the round trip time. The estimated position of the mobile station is improved based on estimated positions of the plurality of access points and wireless signal based distance estimates from the plurality of access points that are determined using a channel model and the round trip time for the wireless signals.
