Abstract: An optical detection system includes a light emitting module, a test strip and a receiving module. The light emitting module includes a light source and a first light shielding unit. The first light shielding unit has a first aperture corresponding to the light source. The test strip includes a cassette and a light permeable test paper. The cassette has a first window, a second window and a sample opening disposed on one surface of the cassette. The first and second windows are disposed corresponding to each other and located on opposite sides of the cassette, respectively. The light permeable test paper is disposed in the cassette. The receiving module includes a second light shielding unit and a photo sensor. The second light shielding unit has a second aperture corresponding to the second window. The photo sensor receives the light beam from the light source and outputs a measurement signal.

Abstract: A handheld electronic device includes a casing, a touch panel, a display and a controller. Either one of the display and the touch panel is fixed onto the casing. The other one of the display and the touch panel is movably coupled to the casing and disposed above the casing or at the exterior of the casing. The controller is installed in the casing and electrically coupled to the touch panel and the display. The operation of the handheld electronic device depends on the positional relation between the display and the touch panel. While maintaining the operation and viewing quality, the cost and the level of complexity of the design of the handheld electronic device can be reduced to improve the product competitiveness effectively.

Abstract: An electronic pet system includes an electronic pet and a glove. The electronic pet includes a first central processing unit (CPU) and a wireless receiver. The glove includes a plurality of accelerometers, a wireless transmitter, and a second CPU. When the glove is moved, acceleration of the accelerometers will be measured. If the measurements of acceleration match a predetermined instruction, the electronic pet will be directed to make a move according to the predetermined instruction.
