Abstract: The invention discloses a method for realizing an arbitrary ultrasonic field. The method uses a pulsed laser generated by a pulsed laser machine, modulated into a specific two-dimensional or three-dimensional light field distribution by a phase-type spatial light modulator, and the specific distribution of light acts on photoacoustic media. Due to the photoacoustic effect, a sound field distribution corresponding to the light field will be generated in the photoacoustic medium. The sound field constitutes a two-dimensional or three-dimensional spatial sound source. The sound waves emitted by the sound source are transmitted through a certain distance. The expected ultrasonic field distribution can be formed on a surface or inside of samples. The invention can transform the coherent ultrasonic field distribution formed on the surface or inside of the target object, simply by adjusting the phase distribution diagram input to the spatial light modulator, which has great flexibility.

Abstract: A touch screen controller provides a host interrupt to a host device operating in a low power consumption mode. The touch screen controller uses gesture templates to detect gestures input via a touch screen. Each gesture template is associated with an event identifier, and each event identifier is associated an application. Each gesture template includes a template identifier, a matching threshold, a criterion, and coordinates corresponding to locations on the touch screen panel. If at least one of the coordinates corresponding to a gesture input via the touch screen satisfies the criterion included in a particular gesture template, the touch screen controller provides a host interrupt with the event identifier corresponding to that gesture template to the host device. In response to receiving the host interrupt with the event identifier, the host device exits the low power consumption mode and opens the application associated with the event identifier.

Abstract: A microwave or millimeter-wave balun is provided. The balun uses three edge-coupled lines along with a plurality of air bridges instead of two edge-coupled lines used in a conventional planar Marchand balun. The first edge-coupled line and the second edge-coupled line are substantially parallel, and the third edge-coupled line is disposed also substantially in parallel between the first edge-coupled line and the second edge-coupled line. The plurality of air bridges are transmission lines between the first edge-coupled line and the second edge-coupled line. The air bridges have total width longer than one half of the total length of the first edge-coupled line or the second edge-coupled line. By combining three edge-coupled-lines and a plurality of air bridges, the Marchand balun has a higher coupling coefficient and increases the operation bandwidth. The microwave monolithic integrated circuit (MMIC) mixer based on the balun can provide compact size compared to conventional ones.
