Abstract:
A hand-held electronic device with calculation operating functions, including a main body, a plurality of number keys disposed on the main body, a display, and at least M operation keys, is disclosed. The display is used for displaying an operation indicator area, a highlight, and a numeral area. Operation indicator area includes N operator indicators arranged in M directions around the reference point. The highlight is used to indicate the selected operator indicator. Numeral area is used to display various numbers. M operation keys are respectively corresponding to M directions of the operator indicators. As one of the M operation keys is triggered, the highlight shifts along the corresponding direction to choose the operator indicator and to perform the corresponding operating functions.
Abstract:
A hand-held electronic device with a plurality of operating functions, comprising a main body, a plurality of number keys disposed on the main body, a display and at least M buttons is provided. The display displays an operation indicator area and a numeral area. The operation indicator area has N operator indicators respectively corresponding to N operators arranged in one or more than one layers along M directions emitted from a reference point. The corresponding operator indicator is indicated by a highlight while one of the operating functions is operated. The numeral area is for displaying the operation value and a result value. Wherein when one of the M operation keys is triggered, the highlight shifts along a corresponding direction to select one of the N operator indicators to perform the corresponding operating function on the operation value. Thereafter the result value is obtained and displayed on the display.
Abstract:
The welding filter device includes a light sensor, a microprocessor, a liquid crystal display, and a user interface. The light sensor senses light to generate a welding signal and a light source intensity signal. The microprocessor comprises a determining module, a control module, a regulating module, and a storage module. The determining module receives the welding signal and determines whether to activate a welding mechanism. The control module receives the light source intensity signal and outputs a control signal. The liquid crystal display presents a first display status according to the control signal. The user interface is used to generate a setting signal; wherein when the liquid crystal display presents the first display status, the regulating module receives the setting signal to regulate the settings so that the liquid crystal display presents a second display status. Furthermore, a method for controlling the welding filter device is also disclosed herein.
Abstract:
A method for detecting operations of a power storage device is disclosed. The power storage device includes an electricity storage unit for storing power output from an electronic device or outputting power to the electronic device. The method includes detecting current between the electricity storage unit and the electronic device to determine whether the electricity storage unit is malfunctioned and causes short circuit, and generating an alarm signal when the electricity storage unit is malfunctioned and causes short circuit.
Abstract:
The present invention relates to a fan control system. The fan control system includes a first micro controller, a second micro controller and a first logic circuit. The first micro controller provides at least one first control signal. The second micro controller is connected to the first micro controller. The second micro controller detects operational status of the first micro controller, and provides at least one second control signal. The first logic circuit receives the first control signal and the second control signal to process logic operation and to generate at least one driving signal to fan. The fan control system of the invention utilizes two micro controllers, when one of the two micro controllers malfunctions, the first logic circuit allows the other micro controller to continue proper operation of the fan, thereby preventing the problem of insufficient heat dissipation that results from malfunction of the single micro controller of a conventional fan control system.

The hollow ceramic casing is fixed on the main body to form a receiving space. The LED chips is received in the receiving space. The package colloid is filled in the receiving space for covering the LED chips.
Abstract:
A lamp body is an enclosing structure that encloses a blue light-emitting crystal to form a LED structure. In a method of manufacturing frame body of the LED, resin, titanium, and fluorescent powder are mixed uniformly to constitute a composition of frame body, then the composing materials being placed into a mould for processing a thermally pressing procedure to thus form a frame body. By the blue light emitted from the blue light-emitting crystal, the fluorescent powder of the frame body may be excited to emit uniform yellow light, which may be further mixed with the blue light to become white light.
