Abstract: An optically transparent force sensor that may compensate for environmental effects, including, for example, variations in temperature of the device or the surroundings. In some examples, two force-sensitive layers are separated by a compliant layer. The relative electrical response of the two force-sensitive layers may be used to compute an estimate of the force of a touch that reduces the effect of variations in temperature. In some examples, piezoelectric films having anisotropic strain properties are used to reduce the effects of temperature.

Abstract: Dynamically modelling geospatial words in social media, in one aspect, generates a word set based on frequencies of words occurring in GPS annotated text data generated by a GPS-enabled device containing latitude and longitude coordinates. Locations are partitioned by mapping GPS coordinates in the GPS annotated text data to a set of discrete non-overlapped locations. A text stream contained in the GPS annotated text data is segmented into time windows. Footprints of locations in time windows are generated. Geospatial weights associated with words in the word set may be generated based on localness of words determined based on the footprints. Words in a text message are extracted and scores are determined for the set of discrete non-overlapped locations associated with the words.

Abstract: A method of calibrating a force sensor that includes an input surface and an array of sensing elements. The input has a number of test locations and is deformable under applied force. The force sensor is mounted in a predetermined test orientation. For each test location of the plurality of test locations on the input surface of the force sensor a predetermined test force to the test location. An element calibration value is measured for each sensing element of the array of sensing elements of the force sensor. An (x, y) deformation map of the input surface of the force sensor corresponding to the application of the predetermined test force to the test location is determined based on the measured element calibration values.

Abstract: An augmented reality display system used to diminish (for example, obscure, obfuscate, hide, make less distracting, block out, “white wash” and/or make less discernible) certain portions of a base image (for example, a user's view of a part of the real world as seen through eyeglasses). Some examples of visual subject matter that can be diminished include: (i) driver distraction phenomena; (ii) advertising; and/or (iii) subject matter the user is not authorized to view.

Abstract: Systems for detecting an amount and/or location of a force applied to a device using a piezoelectric film are provided. One example system can include a transparent piezoelectric film for generating an electric charge in response to a deformation of the film. Electrodes positioned on opposite surfaces of the piezoelectric film can be used to detect the generated electric charge and determine an amount and/or location of force applied to the film based on the generated electric charge. In another embodiment, the system can include a capacitive touch sensor for determining a location of a touch event on the device.

Abstract: A system can include a display, a first device, and a second device all operatively connected to a controller. The first and second devices each use or share at least a portion of the display area. The controller is adapted to transmit during a pixel refresh time period of the display a first signal that is received by the first device. The first sync signal indicates a first time period in which a first operation can be performed in the first device. The controller is also adapted to transmit a second sync signal that is received by the second device indicating a second time period in which a second operation can be performed in the second device. The second time period can be during the pixel refresh time period or outside of the pixel refresh time period.
