    • Aspects of the present invention are directed to the use of optical gain structures that include alternating layers of gain medium and transparent heat conductors in which the gain medium itself functions as a correction optic. The gain medium changes to an optimum or desired shape because of the thermal changes occurring as the materials of the optical gain structure(s) reach a desired optical output condition. At the desired optical output conditions, the gain medium conforms to a desired shape. The desired shape may be, for example, that of an optical surface of a transparent heat conductor. By designing the initial shape of the gain medium such that the physical contact with the transparent heat conductor is maximized at the desired optical output conditions, conductive heat transfer between the gain medium and heat conductor(s) is maximized at the desired optical output condition.
    • 本发明的方面涉及使用包括增益介质和透明导热体的交替层的光学增益结构,其中增益介质本身用作校正光学元件。 由于随着光增益结构的材料达到期望的光输出条件而发生热变化,增益介质变为最佳或期望的形状。 在期望的光输出条件下,增益介质符合所需的形状。 期望的形状可以是例如透明导热体的光学表面的形状。 通过设计增益介质的初始形状,使得与期望的光输出条件下的与透明导热体的物理接触最大化,增益介质和热导体之间的导电热传递在期望的光输出条件下被最大化。

    • The invention provides a handheld projector and a projection method thereof. The handheld projector includes a projection module, a control module, a detecting module and a steering module. The control module drives the projection module to project an image towards an object, which includes a cursor. The detecting module generates a shift signal according to shift of the handheld projector, and transmits the shift signal to the control module. The control modules drives the steering module to rotate the projection module towards an opposite direction of the shift of the handheld projector, so as to make the image projected by the projection module stay in a fixed position of the object. Through the invention, projected image is not easily shocked, and the user only need move the handheld projector when change of the cursor position is desired, and thus operation convenience is greatly enhanced.
    • 本发明提供了一种手持式投影仪及其投影方法。 手持式投影仪包括投影模块,控制模块,检测模块和转向模块。 控制模块驱动投影模块将图像投射到包含光标的物体。 检测模块根据手持投影机的移动产生移位信号,并将移位信号发送到控制模块。 控制模块驱动转向模块以使投影模块朝着与手持式投影仪的移动方向相反的方向旋转,以使由投影模块投影的图像保持在物体的固定位置。 通过本发明,投影图像不容易受到震动,并且仅当需要改变光标位置时用户才需要移动手持投影仪,从而大大提高了操作便利性。

    • An apparatus for determining multipath correlations among a search range of input data, and a method thereof. The multipath searcher comprises a pseudo noise (PN) code generator, a correlator, and a data combiner. The PN code generator generates a first PN code corresponding to a first multipath component of the input data, postpones a first period based on the search range, then generates a second PN code corresponding to a second multipath component of the input data. The correlator is coupled to the PN code generator, and correlates the input data with the first PN code and the second PN code to produce a first correlation and a second correlation. The data combiner is coupled to the correlator, receives the first and the second correlations to determine a primary multipath component with a higher correlation thereto.
