Abstract

The invention relates to a power-saving method of an optical position guiding device (or generally called optical mouse). The method is disclosed to control the frequency of a sensor fetching an image in accordance with the moving speed of the optical position guiding device, meaning that the image-fetching frequency is determined by the variations of the horizontal displacement value and the vertical displacement value so as to save the power of the optical position guiding device. Furthermore, while entering a sleep mode, it is unnecessary for the optical position guiding device to generate a current within a fixed period of time, which is used to drive the image sensor for monitoring if the optical position guiding device moves. Instead, a displacement sensor, such as the mechanical displacement activation device, is utilized to generate a current to interrupt the sleep mode, attaining the power-saving goal.

Conversely, the movement needs to be slower, but the life and power to drive the LED light source and capture the frequency of the image, you can also know when the capture = S electricity. This time period is in step S3. When the first image is equal to the master, the higher the power consumption, the higher the power. And the displacement value and one of the vertical axis vertical displacement === When the image, that is, the horizontal and no specific displacement detected after a specific time, when 0, that is, no displacement, the power saving mode of the optical position guidance device =, That is to enter a power saving mode step S30 for a first waiting period; the main steps of the process include: step S 3 1 for a second waiting period; step S 3 2 for entering an intermittent mode; and steps S34.

1227393 五、發明說明（3) 力，經過此段時間後，使該感應器擷取影像以確定該光學位置引導裝置是否移動（S32);反之，其會進入該間歇模式，此時仍是會固定一段時間後，使該感應器擷取影像以確定該光學位置引導裝置是否移動（S34)。其中，該間歇模式之固定時間係短於該休眠狀態之固定時間。故，習知技術之光學位置引導裝置只有在未移動時才會進入省電模式，然，不管是間歇模式與休眠狀態，都會在一固定時間後產生一電流一驅使該感應器擷取影像，此固定時間愈長則愈省電，但是愈難有機會被喚醒，以監測該光學位置引導裝置是否移動，雖以一間斷時間來控制該感應器進行擷取影像，但還是極為耗電，由於目前藍芽技術曰漸成熟，所以於電流之控制上更為重要，以延長無線光學位置引導裝置使用之時間。因此，如何針對上述問題而提出一種新穎光學位置引導裝置之省電方法，不僅可改善傳統光學位置引導裝置不分移動快慢而使用相同之影像擷取頻率之缺點，更可使用位移觸發裝置改善喚醒機制以提高省電功能，長久以來一直是使用者殷切盼望及本發明人念茲在茲者，而本發明人基於多年從事於相關產品之研究、開發、及銷售實務經驗，乃思及改良之意念，窮其個人之專業知識，經多方研究設計、專題探討，終於研究出一種光學位置引導裝置之省電方法改良，可解決上述之問題。【發明内容】1227393 V. Description of the invention (3) Force, after this period of time, make the sensor capture an image to determine whether the optical position guidance device is moving (S32); otherwise, it will enter the intermittent mode, at this time it will still be After being fixed for a period of time, the sensor is used to capture an image to determine whether the optical position guidance device is moved (S34). The fixed time of the intermittent mode is shorter than the fixed time of the sleep state. Therefore, the optical position guidance device of the conventional technology only enters the power saving mode when it is not moved. However, regardless of the intermittent mode and the sleep state, a current will be generated after a fixed time to drive the sensor to capture images. The longer this fixed time is, the more power is saved, but the harder it is to have the opportunity to be awakened to monitor whether the optical position guidance device is moving. Although the sensor is controlled with an intermittent time to capture images, it still consumes very much power. At present, the Bluetooth technology is gradually mature, so it is more important to control the current to extend the use time of the wireless optical position guidance device. Therefore, how to propose a novel power-saving method of the optical position guidance device for the above problems can not only improve the disadvantages of the traditional optical position guidance device using the same image acquisition frequency regardless of the speed of movement, but also use the displacement trigger device to improve wakeup The mechanism to improve the power saving function has long been the user ’s eager hope and the inventor ’s intentions, and the inventor is thinking and improving based on many years of experience in research, development, and sales of related products. Ideas, poor personal expertise, through various research and design and special discussions, finally developed an improved power-saving method for optical position guidance devices, which can solve the above problems.

Invented the vertical bit rate of the power-saving party of the present invention. When the threshold value of the bit is shifted horizontally, that is, the lifting guide device does not fix the state of the power-saving party's trigger device. Take like. In order to set the guidance and guidance device at the optical position used by the change in the value, the main method of entering the Ming Dynasty is to shift the value horizontally, that is, to decrease the value and capture the fast moving sensor of the sensor. The secondary method of the Ming is to reduce the position of the device according to the value of the change in order to generate a large number of positions that do not need to generate a guide device and interrupt the mobile opticalization of the device, which mostly guides the position of the so-called power-saving position. The capture is slow, the purpose of capturing is to compare the amount of the image, and the vertical sensor shifts the value to take the image to control the image frequency to provide an image, and to control the frequency of the change in the capture of the constant displacement. The purpose is to provide Using a displacement sensor to turn off the sleep to drive can move the current through driving any electric current with or without a sleep mode. In this way, the amount of the image of the water sensor value of the light student is greater than that by which Power-saving optical 'for example mode, which senses the position of the displacement sensor to level out the displacement capture image change frequency, The upper door is guided by the method of the light image: mechanical and enter the sensor to capture the value of the device and the frequency of the image is less than the lower and the water threshold is the time position frequency. The advantages and effects of light in order to generate images. An optical position of the present invention is not to mention the use of the optical position to guide X 'to control the frequency of the image captured by the sensor. # Sa ” The horizontal displacement value and the vertical displacement ^ U determine the frequency of capturing the image. Because the user is still moving or moving very slowly, this saves the NVC _ knife. Furthermore, the optical position is used to guide the installation of the search. , Which generates a current in a fixed time to

Description of the invention (8) Capturing an image ’can achieve the goal of more power saving. The present invention uses a displacement sensor to sense the state of the optical position guidance device in a sleep state, so when a user moves the optical position guidance device again, a current can be input to interrupt the sleep mode 'and drive The sensor directly captures images (S 2 5). Finally, please refer to the fourth diagram A, the fourth B diagram, the fourth C diagram, the fourth D diagram, and the fourth E diagram, which are schematic diagrams of a mechanical structure to wake up the sleep mode according to a preferred embodiment of the present invention; As shown in the figure, in the fourth diagram A and the fourth diagram B, when the metal ball 1 1 0 of the mechanical structure 100 moves through the user, it will collide with a contact point 1 2 0 next to it. This mechanism generates a current to drive the sensor to manipulate the image, and as shown in the fourth figure C, it is transmitted. When the metal ball 11 0 is moved, it will touch a frame 1 3 0 to generate a current. Figure D, which shows an electric current generated through the contact between an upper cover 140 and the lower cover 150 through the movement of the upper cover, and the fourth E drawing, the upper cover 1440 and the lower cover 150 Through a floating design, when moving, the upper cover 140 and the lower modification 150 are connected to each other to generate a current. However, such structures are endless. For example, micro-electromechanical technology is directly placed on the semiconductor. In the manufacturing process, or adding a displacement sensor to the semiconductor, so long as it is produced through the displacement sensor A wake-up contact structure and function, the scope of the invention should be Ming.
