1. Technical Field
The exemplary disclosure generally relates to wireless control devices, and particularly relates to a multi-functional wireless control device having integrated mouse and remote control capabilities.
2. Description of Related Art
Display devices such as projectors, liquid crystal display-televisions, etc. are widespread used in meeting rooms, classrooms etc. for providing visual displays. These display devices are often connected to and controlled by computers to implement some complex operations.
Generally, these display devices (e.g. projectors, liquid crystal display-televisions) are often controlled by wireless control devices. However, the wireless control device connected to the corresponding display device cannot control the computer mutually connecting with the display device. As such, other control devices such as mouse and keyboard are needed to control the computer, which may bring inconvenience to users.
Therefore, there is room for improvement within the art.
Many aspects of the exemplary multi-functional wireless control device can be better understood with reference to the following drawings. These drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the exemplary methods. Moreover, in the drawings like reference numerals designate corresponding parts throughout the several views. Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like elements of an embodiment.

The bottom surface 124 may include a battery receiving portion 1242, a switch 1244, a reset key 1246 and a locating diode 1248 thereon. The battery receiving portion 1242 is configured to assemble a battery therein for providing power supply to the multi-functional wireless control device 100. The switch 1244 is configured to be pressed to send out a switching signal to the control module 140 to switch between the remote controlling mode and the wireless mouse mode. The reset key 1246 is configured to reset the wireless mouse mode. The locating diode 1248 is a laser photodiode configured to send out light when working in wireless mouse mode.
The end surface 126 may include an infrared module 1262 and an indicating diode 1264 thereon both electrically connecting with the control module 140. The infrared module 1262 is configured to trigger and communicate with a digital processing device (e.g. computer, projector, etc.) by sending out infrared signals when working in remote controlling mode, for controlling the digital processing device by operating the remote operating keys 128. The indicating diode 1264 is configured to send out visible rays as a projector laser pointer.
The control module 140 and the processing unit are both assembled and disposed within the shell 120. The control module 140 is a digital signal processor (DSP) configured to process and modulate the signals generated by the operating body 110 to control and establish communication between the operating body 110 and the receiving unit 160.

The mouse key module 146 is configured to receive the corresponding controlling signals generated by the mouse keys 130 (operated by the operator) and transmit the corresponding controlling signals to the control module 140. The displacement sensor 148 is a laser sensing module electrically connecting with the locating diode 148 and the control module 140. The displacement sensor 148 is configured to sense/detect the shift/movement of the light sent out by the locating diode 1248 to determine the coordinates information of the operating body 110 (used as a wireless mouse) and transmit the shift/movement coordinates information to the control module 140. The encoder 150 electrically connects with the control module 140 and is configured to convert the triggering signals into the wireless transmitting codes to avoid frequency interference and transmission interruptions. The transmit module 152 is a dual band antenna module working in frequency of 27.045 MHz and 27.145 MHz in the exemplary embodiment and is configured to communicate with the receiving unit 160 wirelessly. The timer 154 electrically connects with the control module 140 and is configured to set a time to leave the operating body 110 on standby mode or asleep mode.

In use, when the multi-functional wireless control device 100 works in remote controlling mode, the infrared module 1262 and the remote operating keys 128 are used. Then, the user may operate the corresponding remote operating keys 128 of the operating body 110 to trigger and control the digital processing device (e.g. computer, projector, etc.). As the remote operating keys 128 are operated, the controlling signals generated simultaneously are transmitted to the control module 140 for processing. The control module 140 processes the signals and then transmits them to the receiving module 164 of the receive unit 160 by the infrared module 1262, for establishing wireless communication between the operating body 110 and the receiving unit 160. The infrared module 1262 sends out infrared signals to the receiving module 164 of the receiving unit 160, to trigger and control the digital processing device (e.g. computer, projector, etc.).
When the multi-functional wireless control device 100 is needed to work as a wireless mouse, the switch 1244 is operated to choose the wireless mouse mode. Then, the signal channel convertor 144, the mouse key module 146, the displacement sensor 148, the encoder 150, the transmit module 152 and the timer 154 are used. When the multi-functional wireless control device 100 works in wireless mouse mode, the signal channel convertor 144 activates the wireless mouse mode and searches for the proper signal channel and communicating frequency to establish communication between the operating body 110 and the digital processing device (e.g. computer) by the receiving unit 160. When the user moves the operating body 110, the locating diode 1248 sends out light projected on a table to form optical signals. The displacement sensor 148 senses/detects the optical signals generated by shift/movement of the light sent out by the locating diode 1248 and transmits the shift/movement coordinates information to the control module 140. The control module 140 processes the signals and transmits them to the receiving module 164 of the receive unit 160 by the transmit module 152, for controlling the digital processing device. When the user operates the left key 132, the right key 134 and the roller 136 of the operating body 110, the left key 132, the right key 134 and the roller 136 generate the corresponding triggering signals. The triggering signals are transmitted to the encoder 150 to convert the triggering signals into the corresponding wireless transmitting codes and transmit the wireless transmitting codes to the control module 140. The control module 140 processes the signals and transmits them to the receiving module 164 of the receive unit 160 by the transmit module 152, for controlling the digital processing device. The receiving module 164 transmits the wireless transmitting codes to the digital processing device by the interface 162.
It is to be understood that the displacement sensor 148 could also be an infrared sensing module, accordingly, the locating diode 1248 could be an infrared photodiode.
It is to be understood that the interface 162 could be a PS/2 data transmitting port.
It is to be understood, however, that even through numerous characteristics and advantages of the exemplary invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
