Abstract: Systems and methods for reducing connection latency are described herein. More particularly, this specification relates to shortening connection latency between devices operating according to a Bluetooth protocol. Connection latency can be reduced by using the receipt of a wireless packet as a trigger for selectively accelerating a transmission rate of advertising packets. By selectively accelerating the transmission rate advertising packets, a connection interval between two devices can be shortened.

Abstract: A portable device such as a key fob includes a piezoelectric component, such as a vibrator or buzzer, and an accelerometer. Self-testing of the piezoelectric component in the portable device may be achieved by applying a test electrical signal to the piezoelectric component and determining whether a vibration is detected by the accelerometer. If a vibration is detected by the accelerometer, then a determination is made as to whether the vibration detected by the accelerometer matches the test electric signal applied to the piezoelectric component.

Abstract: A technique is provided for displaying pixels of an image at arbitrary subpixel positions. In accordance with aspects of this technique, interpolated intensity values for the pixels of the image are derived based on the arbitrary subpixel location and an intensity distribution or profile. Reference to the intensity distribution provides appropriate multipliers for the source image. Based on these multipliers, the image may be rendered at respective physical pixel locations such that the pixel intensities are summed with each rendering, resulting in a destination image having suitable interpolated pixel intensities for the arbitrary subpixel position.
