Abstract: In an electrocardiography measurement method and device, a signal processor determines a baseline value, a maximum wave amplitude value, and a minimum wave amplitude value in an electrocardiogram signal. When the signal processor determines that a difference of the maximum wave amplitude value minus the baseline value is less than a difference of the baseline value minus the minimum wave amplitude value, the signal processor performs a correction process for correcting the electrocardiogram signal.

Abstract: An electronic device comprises a body, a first image capturing element, a cover and a arm. The body comprises a first surface and a second surface, with the first surface opposite to the second surface. The first image capturing element is disposed on the first surface. The cover is connected to the body, movable between a first cover position and a second cover position, wherein the cover covers the first image capturing element when the cover is in the first cover position, and the first image capturing element is actuated when the cover is in the second cover position. The arm is connected to the cover, pivoting between a first position and a second position, wherein when the arm is in the second position, a recording medium is received on a first end of the arm, and the first image capturing element captures an image data therefrom.

Abstract: A handheld electronic product that is capable of automatically switching between operating modes includes a mouse module for outputting a mouse signal when operated on a plane surface, an angle detection module, and a control module. The angle detection module detects changes in angular orientation between the handheld electronic product and a horizontal plane, and outputs a detection signal. The control module switches to a mouse mode upon determining that the angular orientation indicated in the detection signal is a horizontal orientation, and to a non-mouse mode when otherwise. The control module controls output of the mouse signal when in the mouse mode, and disables output of the mouse signal when in the non-mouse mode.

Abstract: A keyboard structure with a keyboard input function and a sensor pad input function includes a motherboard module, a keyboard module, and a sensor pad module. The keyboard module is electrically connected with the motherboard module, and the keyboard module has a keyboard/sensor pad input function switch unit. The sensor pad module is electrically connected with the motherboard module, and the sensor pad module has a sensor unit disposed under the keyboard module. Therefore, the keyboard/sensor pad input function switch unit is switched in order to selectively use the sensor pad input function of the sensor pad module or the keyboard input function of the keyboard module.

Abstract: A hinge structure applied to a portable electronic device that has a first cover structure and a second cover structure, includes a receiving unit and a hinge unit. The receiving unit is formed on the first cover structure, and the receiving unit has at least one receiving space and two guiding tracks disposed on two opposite inner sides of the at least one receiving space. The hinge unit is disposed on the second cover structure. The hinge unit has at least one hinge body received in the at least one receiving space and two pivots respectively disposed on two opposite lateral sides of the at least one hinge body and slidably received in the two guiding tracks. Therefore, the first cover structure and the second cover structure pivot to each other and slid with respect to each other by matching the two pivots and the two guiding tracks.

Abstract: A portable computer system for expanding usage function includes an independent host unit and a function expansion unit. The host unit at least includes a motherboard module, a first power supply module, a display module, a wireless transmission module, and a first I/O interface module. The motherboard module, the first power supply module, the display module, the wireless transmission module and the first I/O interface module are electrically connected with the motherboard module. In addition, the display module has a built-in touch pad. The function expansion unit at least includes a keyboard module and a bracket module. The keyboard module is electrically connected with the motherboard module of the host unit. The bracket module is pivoted on the keyboard module, and the bracket module is detachably and electrically connected with the host unit.
