Abstract: A method for touchless gesture recognition is provided. The method includes transmitting ultrasonic signals via a speaker. The method includes generating ultrasonic signals. The method includes receiving the reflected ultrasonic signals from an object via two or more microphones. The method includes computing a frequency shift according to the reflected ultrasonic signals. The method includes identifying a gesture that corresponds to a movement of the object according to the frequency shift. The method includes performing a function that corresponds to the gesture.

Abstract: An intervertebral implant is a porous structure formed of a plurality of metal balls, and the intervertebral implant includes a bone support area and a bone growth area. The bone support area and the bone growth area each have a plurality of connecting holes, and a porosity of the bone support area is smaller than that of the bone growth area.

Abstract: An optical scanning module with linear CMOS image sensor (linear CMOSM) applied to scanners or multi-function printers is disclosed. The optical scanning module includes a light source for emitting light, a reflection mirror group, a focus lens group, and a linear CMOS image sensor having at least one linear CMOS image sensor unit and one A/D analog-digital converter. The light source can be a cold cathode fluorescent lamp (CCFL), a Xenon lamp or linear LED. Light emitted from the light source projects onto an object being scanned. Then the light reflected by the object being scanned becomes scanning light, passing through the reflection mirror group and the focus lens group and being focused on the linear CMOS image sensor for being converted into electrical signal. By A/D conversion of the linear CMOS image sensor unit in the linear CMOS image sensor, signal is sent out in USB or LVDS format so as to achieve high scanning speed, low distortion, large depth of focus and convenient transmission.

Abstract: The present invention is generally related to an anti-leaking cartridge and anti-leaking ink. The anti-leaking ink comprises: an organic solvent, which is selected from the group consisting of diethylene glycol, triethylene glycol, triethanolamine amine extra pure, polyethylene glycol 200, and ethylene glycol and functions with at least one seal member for avoiding leakage; at least one dye dissolved in the organic solvent; a buffer solution maintaining the pH value of the anti-leaking ink in between 6.0 to 8.0; an antibacterial avoiding that the properties of the ink is changed; surfactant, which homogenizes the aquas of ink and the organic solvent; and de-ionized water.

Abstract: A portable electronic device with fat measuring function and a fat measuring method thereof are provided. The portable electronic device includes a first button, a second button and a fat-measuring controlling circuit. The first button and the second button are made from a conductive material. The fat-measuring controlling circuit is coupled with the first button and the second button respectively. When the user touches the first button and the second button, the fat-measuring controlling circuit measures an electrical signal between the first button and the second button to generate the user's body fat rate.
