Abstract: An unmanned vehicle includes a vehicle body having an accommodating space, an arm assembly coupled to the vehicle body, and a floating member connected to a bottom surface of the vehicle body. The arm assembly includes a first rotating member, a second rotating member coupled to the first rotating member, and a propeller. The propeller includes a rotatable axle coupled to the second rotating member and extending along a rotating axis. The second rotating member can turn the propeller by rotating the rotatable axle about the rotating axis. The first rotating member can rotate and effect a movement of the second rotating member so as to selectively adjust the rotatable axle to align the rotating axis with a first axial direction and a second axial direction. The arm assembly can rotate relative to the vehicle body to selectively rotate into or out of the accommodating space.

Abstract: A printing-height increasable three-dimensional printer includes a base, an elevating shaft, an elevating platform, a first driving module, a working platform, a printing nozzle, and a second driving module. The elevating shaft is connected to the base. The elevating platform is slidably connected to the base. The first driving module is configured to drive the elevating shaft to make the base move along a direction, and is configured to drive the elevating platform to reversely move relative to the base along the direction. The working platform is slidably connected to the elevating platform. The printing nozzle is connected to the base and is configured to print on the working platform. The second driving module is configured to drive the working platform to move between the printing nozzle and the elevating platform.

Abstract: An unmanned vehicle includes a vehicle body and at least one arm assembly. The arm assembly is coupled to the vehicle body. The arm assembly includes a first rotating member, a second rotating member, and a propeller. The second rotating member is coupled to the first rotating member. The propeller includes a propeller rim encircling an outer edge of the propeller and a rotatable axle coupled to the second rotating member. The the rotatable axle extends along a rotating axis. The second rotating member is configured to turn the propeller by rotating the rotatable axle about the rotating axis. The first rotating member is configured to rotate and effect a movement of the second rotating member so as to selectively adjust the rotatable axle to align the rotating axis at least with a first axial direction and a second axial direction.

Abstract: An input device constructed in a carrier electronic apparatus comprises a letter button module and a number button module. The letter button module has a plurality of letter buttons to represent different letters respectively, and the number button module has a plurality of number buttons to represent different numbers respectively. The number buttons are separated from the letter buttons by being located in the intervals formed by adjacent rows of the letter buttons. The size, form, and color of the number buttons are different to those of the letter buttons.

Abstract: A rotary positioning structure is disclosed for a frame. The frame comprises a housing and a spindle hole disposed on the rear of the housing. The rotary positioning structure comprises elastic members and a rotary stand. Each of the elastic members comprises a tenon and the elastic members are arranged on a circular path surrounding the spindle hole. The rotary stand comprises a rotary shaft and a groove. When the rotary shaft is inserted into the spindle hole, the groove engages with the tenon so that the housing is supported in a first upright position by the rotary stand; also after said rotary shaft is inserted into said spindle hole and then the rotary stand is pivoted on the rotary shaft, the groove engages with another tenon of the elastic members so that the housing is supported in a second upright position by the rotary stand.

Abstract: A method and system are disclosed for decimating an indexed set of data elements to generate a decimated set of data elements. The indexed set of data elements are grouped into groups of at least two data elements per group. The indexes of the data elements in each group are used to address a look-up-table (LUT) that is pre-programmed to perform the decimation operation. For each group of data elements presented to address the LUT, a decimated data value is output from the LUT. The decimated data value is a function of the data values of the corresponding data elements addressing the LUT.

Abstract: A light guiding system for multiple areas is provided for a mobile communication device with a keypad module. The light guiding system includes a lighting source unit, a light guiding unit, and a control circuit unit. The lighting source unit has at least one light emitting member for generating a single lighting or a combined lighting. The control circuit unit is utilized for controlling the light emitting members of the lighting source unit to emit the single or combined lighting. The light guiding unit is provided for guiding the single or the combined lighting to a portion of or an entire area of the keypad module. Accordingly, the portion of the keypad module or the entire area of the keypad module is lit by the single/combined lighting. The different lighting areas of the keypad module provides a guiding effect that improves the using efficiency.

Abstract: Aspects of the invention may include a method updating a color look-up table (CLUT) for a next line of graphics before a current line of graphics has been completely read out of a graphics FIFO and assigned color pixel values. The method may include the step of formatting or arranging the CLUT into a plurality of sub-CLUTs. Each one of the sub-CLUTs may include pixel color values for each one of a plurality of pixels which may include a line of the graphics image data. Pixel color values may be read from within a first selected sub-CLUT, the first selected sub-CLUT comprising pixel color values for a first line of the graphics image data. The read pixel color value may be applied to the current first line of the graphics image data. While the read pixel color value is being applied to the current first line, pixel color values for a second selected sub-CLUT may be updated. The second selected sub-CLUT may include color pixel values for a second line of the graphics image data.
