An electronic device includes a main body; at least one proximity sensor arranged in the main body to detect a motion of a user in a predetermined range from the main body. A memory arranged in the main body store a relationship table defining a relationship between an operation event and an executable function. The operation event includes: the times of the proximity of a user to the main body, the duration of a stationary state of the user relative to the main body, and the distance of the movement of a user with respect to the main body. In addition, includes a processor receiving data from the at least one sensor determining an operation event and executing an executable function according to the relationship table.
Abstract:
A clock range setting device including a horizontal counter, a filter unit, a clock detecting unit, a first infinite impulse filter (IIR filter), and a clock range modulator is provided. The horizontal counter counts a horizontal counter value. The filter unit obtains a lead clock of each teletext video signal according to a lead clock range, and generates a corresponding clock intermediate value. The clock detecting unit detects level changes of the lead clock of each teletext video signal according to the clock intermediate value, so as to generate a corresponding current clock cycle number. The first IIR filter generates corresponding number mean value according to the current clock cycle numbers sequentially received by the first IIR filter. The clock range modulator sets the lead clock range corresponding to each teletext video signal according to the current clock cycle number, the number mean value, and the horizontal counter value.
Abstract:
A tracking detection and alarm method which is applied to a navigation device use a number of positioning data points retrieved from a navigation module of the navigation device. A number of deflections and a number of average speeds that correspond to the position data points are calculated and generated. A number of maximum deflections are calculated and generated according to the average speeds. When a deflection of a positioning data point is greater than a maximum safe deflection thereof, one is added to a frequency of unsafe driving instances. When the frequency of unsafe driving instances is greater than a preset threshold value, an unsafe driving alarm is activated.

Numerical methods for simulating subsonic flows and solving inverse problems based on the new two-dimensional Euler equations in Lagrangian formulation. A transformation to derive the Euler equations in Lagrangian plane to simplify the computational grid and to minimize the numerical diffusion caused by the convective flux. Constructed is a numerical scheme, the dimensional-splitting with hybrid upwind flux operators, where the two-dimensional Riemann problem was solved in the Lagrangian plane. The method, solving the inverse geometry shape design problem in Lagrangian plane, gives the flow filed results and the geometry shape concurrently.
Abstract:
A light emitting diode and a fabricating method thereof are provided. A first-type semiconductor layer, a light emitting layer and a second-type semiconductor layer with a first surface are sequentially formed a substrate. Next, the first surface is treated during a surface treatment process to form a current-blocking region which extends from the first surface to the light emitting layer to a depth of 1000 angstroms. Afterward, a first electrode is formed above the current-blocking region of the second-type semiconductor layer, and a second electrode is formed to electrically contact to the first-type semiconductor layer. Since the current-blocking region is formed with a determined depth within the second-type semiconductor layer, the light extraction efficiency of the light emitting diode may be increased.
Abstract:
An electronic label system is provided which includes a data source having information to be displayed by an electronic label. An optical source such as an LED array broadcasts optical signals modulated with the data source data to plural electronic labels. Each electronic label has an optical receiver which receives the modulated optical signals and also receives unmodulated optical signals to supply power to an energy storage device. A mode switch switches the optical receiver between a signal reception mode and an energy storage device power-supplying mode. One or more bistable displays display the data received from the modulated optical signals. Through the use of bistable displays, the power consumption of the electronic label is greatly reduced while use of a single receiving element for receiving both the signal light and power storage light reduces the number of components needed to assemble the electronic label, thus reducing cost.
