Abstract: An ultrasonic lamp control method is provided. The control method includes the following steps. The ultrasonic lamp emits a first burst, and detects whether a first echo is received within a fixed period of time after the emission of the first burst. If the first echo is received within the fixed period of time, then the ultrasonic lamp neglects the first echo and emits a second burst. The ultrasonic lamp detects whether a second echo is received within the fixed period of time after the emission of the second burst. If the second echo is received within the fixed period of time, then the ultrasonic lamp enters a control mode.
Abstract: A method for swapping display contents between a first and a second screen. The first screen is a primary screen. A window is displayed on one of the first and the second screen. The method includes: calculating a window movement distance according to a relative position between the first and the second screen; performing swapping to set the second screen as the primary screen; obtaining a coordinate of the window after swapping; obtaining a first coordinate by adding the window movement distance to the coordinate of the window after swapping if the window is located in the first screen before swapping; obtaining a second coordinate by subtracting the window movement distance from the coordinate of the window after swapping if the window is located in the second screen before swapping; moving the window from one of the first and the second screen to the other.
Abstract: An integer division circuit with allowable error is described, what a signal processing apparatus includes a pointer, a first left shifter, a second left shifter, a subtractor, a multiplier, and a right shifter. The pointer searches for a most significant non-zero bit of a divisor and outputs a most significant byte value. The first left shifter performs a shift operation according to the most significant byte value, so as to generate a first exponential coefficient. The second left shifter performs a shift operation according to the most significant byte value, so as to generate a second exponential coefficient. The subtractor calculates a multiplier factor according to the divisor, the first exponential coefficient, and the second exponential coefficient and outputs the multiplier factor to the multiplier. The multiplier multiplies an input value with the multiplier factor and outputs a result to the right shifter. The right shifter outputs a calculation result.
