Abstract: An electronic device includes a substrate, a dimming unit, an antenna unit and a protective layer. The substrate includes a display area and a peripheral area, wherein the peripheral area surrounds the display area. The dimming unit is disposed in the display area. The antenna unit is disposed in the peripheral area. The protective layer is disposed in the peripheral area. In the top view direction of the electronic device, the protective layer overlaps at least part of the antenna unit, and is disposed on at least part of the antenna unit.

Abstract: A portable electronic device with camera function and an image capture method with auto exposure control. The disclosed method comprises the following steps: obtaining a pre-view frame from a camera module; dividing the pre-view frame into a plurality of blocks and calculating representative brightness values of the blocks; assigning weight values to the blocks according to the representative brightness values; obtaining a weighted brightness value by performing a weighted operation on the representative brightness values based on the weight values of the blocks; setting an auto exposure parameter of the camera module based on the weighted brightness value; and controlling the camera module for capturing images based on the auto exposure parameter.

Abstract: Systems and methods for measuring flow velocities, including ultrasound systems, are provided. A Doppler angle between a direction of ultrasound signals and an axis of a flow may be estimated to improve the accuracy of the flow velocity estimation that is based on Doppler effects. A sensor may be mounted on or in an ultrasound probe to obtain a reference orientation of the ultrasound probe and an orientation of the ultrasound probe relative to the reference orientation when the ultrasound probe is moved to other positions. The Doppler angle may be estimated based on the orientation of the ultrasound probe.

Abstract: A method for time display, and more particularly, a method that automatically changes the backdrop of time display according to a value of time, e.g. changing the backdrop according to hour, date, month, season, or year. Therein, the method includes: acquiring a value of time provided by a system; showing a backdrop picture according to the value of time; and displaying the value of time on the backdrop picture. Hence, the method can make time display full of variety and diversity to satisfy the recent requirements of people.
