Abstract: A computer cursor control apparatus operating in either the mouse mode or the non-mouse mode is determined by the switch signal. When the computer cursor control apparatus is operating in the mouse mode, the cursor-moving module calculates the cursor-moving signal and outputs it on the monitor of a host for display. On the other hand, when the computer cursor control apparatus is operating in the non-mouse mode, the cursor-moving signal and the pressuring signal, generated by the cursor-moving module and pressure sensing unit respectively, are packaged together and outputted to the host. In response to the cursor-moving signal, the host displays a moving trace on the monitor, with the thickness of the moving trace varying based on the pressuring signal.

Abstract: A computer cursor control apparatus operating in a mouse mode or a non-mouse mode in response to a switch signal is provided. When operating in the mouse mode, the computer cursor control apparatus outputs a wireless signal to a wireless signal receiving unit for determining the displacement of the computer cursor control apparatus to generate a cursor-moving signal, and then display the cursor-moving signal on the monitor of a host. On the other hand, in the non-mouse mode, the pressuring signal is packeted into the wireless signal transmitted from the computer cursor control apparatus such that the host receives not only the cursor-moving signal through the wireless receiving module, but also receives the pressuring signal. In addition, the host displays the cursor-moving signal on the monitor as a moving trace with a thickness depending on the pressuring signal.

Abstract: A laser pointing device having a laser safety apparatus is provided. The laser pointing device includes a laser sensor and a switch. The laser sensor is coupled to a laser diode and a controller. The switch has an end coupled to a power, and another end electrically coupled to the laser diode. When the laser pointing device is placed on a surface, the switch is in an ON state such that the power and the laser diode are electrically connected/When the laser pointing device is away from the surface, the switch is in an OFF state such that the power and the laser diode are electrically disconnected.
