Abstract: A content detection device is provided. The content detection device includes a first sensor and a controller. The first sensor is disposed near a space. The controller is coupled to the first sensor and detects a state of the first sensor. The controller performs a determination operation to determine whether an object is disposed in the space according to the detected state of the first sensor.

Abstract: A hydroponic device includes a water tank, a drain pan, a hydroponic module and a light emitting diode module. The water tank delivers water to the drain pan via a drain pump. The water is then dispensed to each pot body of the hydroponic module. Each pot body includes an inner pot and an outer pot. Water inside the inner pot will flow to the outer pot through the draining hole. Water will flow out of an overflow outlet and re-enter the water tank if the water level is higher than the overflow outlet. The light emitting diode module is disposed above the hydroponic module.

Abstract: A portable computer includes a computer body and a keyboard. The keyboard includes a plurality of keys and a space bar. The space bar includes a base frame, a touch pad, an elastic element and a key switch. The touch pad is elevatably disposed on the base frame, and one surface of the touch pad can provide a cursor of the portable computer. The elastic element is disposed between the base frame and the touch pad, and elastically supports the touch pad. The key switch is disposed on the other surface of the touch pad. When one of the keys is clicked, the computer body disables the touch pad and enables the key switch.

Abstract: An electronic device is disclosed, which includes a touch display module, a frame for placing the touch display module, plural elastic pieces extended from a sidewall of the frame, a casing, a fastener, and plural adjusting screws. The fastener fastens the frame to the casing. The adjusting screws are inserted in the elastic pieces and are screwed in the casing. The depth of the adjusting screws screwed in the casing can be adjusted for adjusting a relative height between the touch display module and the casing.
