## Background
BACKGROUND OF THE INVENTION
The present invention relates generally to a computer mouse and, more particularly, to a computer mouse having infrared light therapy.
Computers and other products using computer mice and other pointing devices are commonplace in both the business and personal settings. Typically, a user is required to direct movement of a cursor on a computer screen by physically moving the user's hand to move the mouse or by moving individual fingers to direct movement of a track ball. Repetitive stress injuries and other maladies, such as, arthritis, tendonitis, and carpal tunnel syndrome, may be further inflamed or exacerbated by using a computer mouse.
Light emitting diode (LED) technology is capable of delivering light deep into tissues of the body. Various wavelengths are said to be optimal for pain treatment and wound healing. LED technology has been shown to be helpful in relieving pain and in improving healing. However, therapy of repetitive stress injuries and other maladies described above often requires halting mouse movement while the therapy is applied.
It would therefore be desirable to have an apparatus capable of LED technology therapy while maintaining the ability to use a mouse, or other such computer peripheral, at the same time.
BRIEF DESCRIPTION OF THE INVENTION
The present invention provides an apparatus for promoting healing from repetitive stress injuries that overcomes the aforementioned drawbacks. A hand-held computer peripheral control apparatus, such as a computer mouse, has a motion sensing device for determining movement of the apparatus body relative to a reference point. The apparatus of the present invention also has a plurality of infrared LEDs that emit infrared light toward a user's hand.
In accordance with another aspect of the invention, a hand-manipulated computer peripheral includes a body having a first surface portion and a second surface portion. At least one motion sensing device is positioned adjacent to the first surface portion and is configured to determine movement of the body relative to a reference. The peripheral also includes a plurality of infrared LEDs positioned adjacent to the second surface portion and configured to emit infrared light toward a hand of a user.
In accordance with another aspect of the invention, a method of manufacturing a hand-manipulated computer apparatus includes attaching a movement detection device to a body of a hand-manipulated computer apparatus and configuring the movement detection device to monitor movement of the body relative to a surface. The method also includes attaching a bank of infrared LEDs to the body, and aligning the bank of infrared LEDs to emit infrared light toward a user's hand when the user's hand is positioned to move the body relative to the surface.
According to another aspect, the invention is embodied in a computer system including a computer and a mouse connected to the computer. The mouse includes a body, a movement sensing device positioned adjacent to the body and configured to detect planar translation of the body, and a plurality of infrared LEDs positioned adjacent to the body, each infrared LED oriented to emit infrared light in a direction toward a hand of a user.
Various other features and advantages of the present invention will be made apparent from the following detailed description and the drawings.

In one embodiment, as shown in FIG. 3a, at least a portion of top portion 20 is constructed of a material translucent to infrared light 34. The plurality of infrared LEDs 18 is positioned within an interior volume 36 of peripheral 10 and positioned to emit infrared light 34 exterior to peripheral 10.
In another embodiment, as shown in FIG. 3b, a plurality of apertures 30 are formed in top portion 20. The plurality of infrared LEDs 18 are aligned with the plurality of apertures 30 and may extend into or through the plurality of apertures 30.
FIG. 4 shows a cutaway view of the bottom of the peripheral 10. Peripheral 10 includes an electronics board 38 having a plurality of electronic components 40 connected thereto to provide the electrical functions of peripheral 10. An movement sensing device 42 determines planar movement of peripheral 10 relative to a surface such as a mouse pad (not shown). In a preferred embodiment, movement sensing device 42 is an optical transceiver comprising an LED emitter and a receiver to sense reflected light from the LED emitter. However, it is contemplated that movement sensing device 42 may be a ball 44 configured to optically or mechanically sense a movement direction of peripheral 10. Electrical functions of the left button 12, right button 14, and scroll wheel 16 are also provided via the plurality of electronic components 40.
A power bus 46 provides electrical power to the plurality of electronics 40 and to the plurality of infrared LEDs 18. Voltage on the power bus 46 is preferably supplied by a battery 48. Alternatively, voltage on the power bus 46 may be supplied via a USB connector 50 and cable 52 connected to a computer power supply (not shown). In a preferred embodiment, battery 48 is a rechargeable battery. A pair of contacts 54 is connected to the power bus 46 that couple with a pair of contacts 56 of a docking station 58. The docking station 58 provides recharging current to the rechargeable battery 48 to recharge the rechargeable battery 48 when the peripheral 10 is not in use.
Still referring to FIG. 4, peripheral 10 includes a controller 60 configured to control a powered state of the plurality of infrared LEDs 18. In a preferred embodiment, controller 60 is configured to control on and off powered state of the plurality of infrared LEDs 18. Switch 24 is connected to controller 60 and allows a user to input a desired powered state of the plurality of infrared LEDs 18. Controller 60 is preferably configured to control an on and off powered state of each infrared LED 18 individually. In this manner, the desired powered status may indicate that the controller 60 turn on all infrared LEDs 18, turn off all infrared LEDs 18, or control the infrared LEDs 18 according to a predefined pattern. It is contemplated, however, that controller 60 may be configured to control the powered state of a group or groups of infrared LEDs 18 as a whole.
FIG. 5 shows a schematic block diagram of a computer 64 preferably connected to peripheral 10 via a wireless communications link 66 between a wireless communication circuit 68 of peripheral 10 and a wireless communication circuit 70 of computer 64. Alternatively, peripheral 10 and computer 64 may be interconnected and communicate via USB communication circuits 72, 74. Controller 60 is configured to send cursor commands via wireless communications link 66 to processor 76 of computer 64 for cursor commands such as button clicks and cursor coordinate modification. Cursor commands sent to a cursor control 77 are determined from buttons 78 and motion sensor 80.
Switch 24 preferably includes a number of intermediate positions that may be used to set a timer 62. Preferably, timer 62 controls a time in which an individual or a group of infrared LEDs 82 remains in a particular powered state. For example, timer 62 may cause controller 60 to toggle the powered state of a group of infrared LEDs 82 to an off state upon the expiration of a time threshold. Alternatively, timer 62 may set a sequence delay time between the off state of one infrared LED and the on state of another infrared LED.
Controller 60 may set timer 62 according to a particular predefined pattern. For example, the predefined pattern may include turning on a group of infrared LEDs 82 and, after timer 62 reaches a threshold, turning off the group of infrared LEDs 82. The predefined pattern may also indicate a delay time between the turning off of a group of one or more infrared LEDs 82 and the turning on of another group.
Still referring to FIG. 5, alternatively or in addition to the controller 60 controlling the powered states of the infrared LEDs 82, computer 64 may programmed to control the powered states of the infrared LEDs 82 via wireless communications link 66. A computer program stored in memory 84 may cause the computer 64 to transmit instructions to peripheral 10 causing the powered states of the infrared LEDs 82 to toggle between on and off states. Display 86 may include a graphical user interface (not shown) allowing the user to set, via keyboard or cursor input, the on state, off state, and predefined pattern of the infrared LEDs 82.
The invention, as described above, stimulates a user's hand to aid in decreasing swelling, reducing inflammation, and reducing pain. The user is able to directly re-energize the body/hand at the cellular level, thus promoting a dispersion of pain and preserving the prophylactic effects of and the dramatic increase in blood flow in the region stimulated by the infrared LEDs. By combining the functions of a computer peripheral with that of infrared therapy, computer users may reduce pain, promote healing, and provide a curative methodology to their body/hand without the need to stop working, gaming, etc. for a session of therapy.
Therefore, the invention is directed to a hand-manipulated computer peripheral including a body having a first surface portion and a second surface portion. At least one motion sensing device is positioned adjacent to the first surface portion and is configured to determine movement of the body relative to a reference. The peripheral also includes a plurality of infrared LEDs positioned adjacent to the second surface portion and configured to emit infrared light toward a hand of a user.
