Abstract: A touch-screen input/output device including a touch sensor, a display, a display control module, a touch sensor control module and a synchronizer module. The touch sensor is overlaid on a display. The display control module is communicatively coupled to the display and converts video data into a serial bit stream video display signal include one or more blanking intervals. The touch sensor control module is communicatively coupled to the touch sensor and determines touch events and location of the touch event on the touch sensor during one or more touch sensor scan cycles. The synchronizer module is communicatively coupled between the display control module and the touch sensor control module, and interleaves the one or more touch sensor scan cycles with the one or more blanking intervals of the video display signal.

Abstract: The present disclosure provides various approaches for smart area monitoring suitable for parking garages or other areas. These approaches may include ROI-based occupancy detection to determine whether particular parking spots are occupied by leveraging image data from image sensors, such as cameras. These approaches may also include multi-sensor object tracking using multiple sensors that are distributed across an area that leverage both image data and spatial information regarding the area, to provide precise object tracking across the sensors. Further approaches relate to various architectures and configurations for smart area monitoring systems, as well as visualization and processing techniques. For example, as opposed to presenting video of an area captured by cameras, 3D renderings may be generated and played from metadata extracted from sensors around the area.

Abstract: A method for reducing line display latency on a touchpad device is disclosed. The method comprises storing information regarding a plurality of prior touch events on a touch screen of the touchpad device into an event buffer. It further comprises determining an average speed and a predicted direction of motion of a user interaction with the touch screen using the plurality of prior touch events. Next, it comprises calculating a first prediction point using the average speed, the predicted direction, and a last known touch event on the touch screen. Subsequently, it comprises applying weighted filtering on the first prediction point using a measured line curvature to determine a second prediction point. Finally, it comprises rendering a prediction line between the last known touch event on the touch screen and the second prediction point.

Abstract: A passive stylus with a deformable tip is described herein. In one embodiment, a thin annular body configured to be hand-held with a chisel shaped tip disposed at the first end of the body is provided. The chisel shaped tip includes a deformable material such that the chisel shaped tip is operable to interface with a touch a sensitive surface with a detectable surface area when a first pressure is exerted on the body and translated to the chisel shaped tip. The chisel shaped tip is operable to interface with the touch sensitive surface with a second detectable surface area, this one different from the first detectable surface area, when a second pressure is exerted on the body and translated to the chisel shaped tip. The stylus may include a second tip on the back end for providing an erase function.
