A miniaturized touch keyboard structure includes a keyboard and at least one touchpad. The keyboard includes a plurality of control keys and a blank key and the keyboard includes at least one control module arranged therein. The touchpad is directly arranged on the keyboard with one of control keys of the keyboard being converted into the touchpad. The touchpad is electrically connected to the control module. A relative position of the touchpad with respect to the blank key is such that the touchpad is located immediately leftward or rightward or both leftward and rightward of the blank key and the touchpad has a surface area that is smaller than or substantially equal to 2&#xd7;2 cm. Further, the touchpad has touch sensitivity and speed that are controlled by predetermined software.

Miniaturized touch keyboard structure

The forward tracking system contains a moving carrier and a remote control device. The moving carrier contains a control module, a frame, and at least a driving unit. The control module directs the driving unit to move or turn the moving carrier. The frame has a first and a second IR (infra-red) receivers to detect the user's turning left or right, and a first supersonic detector to detect a distance from the user. The remote control device contains at least an IR transmitter signally linked to the first and second IR receivers. When a user is in front of the moving carrier, the first and second IR receivers, and the first supersonic detector provide lateral movement and forward distance detection, so that the moving carrier automatically follows the user at a constant distance behind as the user moves straight ahead, or turns left or right.

Forward tracking system and control method thereof

The forward and lateral tracking system contains a moving carrier and a remote control device. The moving carrier contains a front frame, a first lateral frame, a second lateral frame, and at least a driving unit. The front frame has a first IR (infra-red) receiver and a second IR receiver for detecting left and right movement, and a first supersonic detector for detecting forward distance. The first lateral frame has a second supersonic detector and a third supersonic detector for detecting left and right movement, and a third IR receiver. The second lateral frame has a fourth supersonic detector and a fifth supersonic detector for detecting left and right movement, and a fourth IR receiver. The remote control device contains at least an IR transmitter signally linked to the IR receivers.

Forward and lateral tracking system and control method thereof

A foldable trolley includes a chassis frame, which includes a front wheel set and a rear wheel set between a slidable plate is arranged for driving the rear wheel set to collapse toward the front wheel set. The first frame is coupled to a first driver device and is mounted on the slidable plate. The second frame is coupled to a second driver device and connected to the first frame. The first driver device drives the first frame to bend toward the front wheel set and the first frame drives the slidable plate to move simultaneously so as to have the rear wheel set to collapse towards the front wheel set. The second driver device drives the second frame to bend toward the rear wheel set so as to achieve an effect of multiple-stage folding to effectively reduce the overall size after folding.
