摘要： Disclosure is related to a light tracing method, and an apparatus thereof. According to one embodiment of the invention, the apparatus is such as an optical indexer. The method for determining a moving direction is performed based on an optical constructive or destructive interference pattern made by reflected lights received by a sensor chip. In particular, the coherent light may be preferably used in order to enhance the interference effect. In an exemplary embodiment, the method includes firstly the sensor pixels in the sensor chip receiving the reflected light, and calculating the energy. Next, within a time slot, the energy state of each sensor pixel can be calculated. A moving vector may be determined from a difference between the binary energy states of the adjacent sensor pixels. The binary energy state is based on a comparison between every sensor pixel and a statistic average within the sampling time slot.

摘要： Disclosure is related to an optical sensor array apparatus. According to one embodiment of the invention, multiple sensor pixels are arranged as an array and forming a sensor array. Every comparator circuit is connected to one sensor pixel so as to calculate its energy state. A light source such as laser is installed in the apparatus. A control circuit is provided to recognize the sensor pixels' energy states for determining the spatial interference difference made by the reflected ray. The sensor array apparatus may be adapted to various surfaces since the light intensity and exposure time is able to be modulated as a compensation mechanism.

摘要： Disclosure is related to a cursor control apparatus and a method for controlling the cursor. The cursor control apparatus essentially includes a light-emitting unit for emitting lights, a housing having a light passage thereon, a light-sensing unit and a control unit. The lights are emitted to outside the apparatus via the light passage. The light-sensing unit then receives the reflected lights from a surface via the passage, especially the lights reach a plurality of sensing cells arranged in an array. The control unit is used to control the energy of the emitting lights, and control the light-sensing unit to receive the lights. After that, the energy received by every sensing cell in an interval can be computed and find the spatial interference difference of energy. The difference is made to determine a moving direction, for example the cursor's movement with the movement of user's finger around the light passage.

摘要： An SCR provides for increased holding voltage by decoupling the pnp and npn parasitic bipolar transistors of the SCR. In one embodiment, a N+ region is placed between the n+ region and the p+ region normally associated with conventional SCR devices, to formulate a new resistance. The new resistance is manifested to allow more current to flow through the new resistance rather than through the SCR parasitic pnp bipolar transistor. Since the parasitic pnp bipolar transistor no longer turns on as strongly as it would otherwise without the low resistance path through the new resistor, the holding voltage of the SCR is raised.
摘要翻译： SCR通过去除SCR的pnp和npn寄生双极晶体管来提供增加的保持电压。在一个实施例中，N +区域被放置在通常与常规SCR器件相关联的n +区域和p +区域之间，以形成新的电阻。新的电阻表现为允许更多的电流流过新的电阻而不是通过SCR寄生pnp双极晶体管。由于寄生pnp双极晶体管不再像以前那样强烈地导通，而没有通过新电阻的低电阻路径，所以SCR的保持电压升高。
