Abstract: The present invention relates to an obstacle detection device, adapted for an autonomous mobile system, which comprises: a conducting wire, a first unit and a second unit. The first unit further comprises a first conducting part, electrically connected to an end of the conducting wire; and the second unit further comprises a second conducting part, electrically connected to another end of the conducting wire other than that connecting to the first conducting part. As an abnormality, such as the autonomous mobile system comes into contact with an obstacle, or misses a step, is happening and detected by the obstacle detection device, a reactive force will be generated to force the two conducting parts to contact with each other so as to enable an electrical conduction for issuing an electrical signal to the control unit of the autonomous mobile system and thus enabling the autonomous mobile system to react with respect to the abnormality.

Abstract: An obstacle and cliff avoiding system is disclosed, which is substantially a movable chassis having at least a displacement sensor arranged thereon. In a preferred embodiment, each displacement sensor is tilted by a specific angle with respect to a surface detected thereby while being driven to move in circle by a rotating apparatus for enabling the same to scan a defined fan-like area or the circular area around the chassis in a circulating manner. As each displacement sensor is tilted by the specific angle and is initiated to issue a working signal, the paths of signal emission and reception of each sensor are defined by the specific angle, whereas the reflected working signal received by the sensor is sent to a control unit to be compared with the working signal so that the control unit is able to evaluate whether there is an obstacle or a drop in front of the moving direction of the movable chassis and thus control the chassis to maneuver around the obstacle or the drop.

Abstract: The present invention provides a complementary metal-oxide-semiconductor (CMOS) image sensor structure and the potential reading method employing the same. The integration area composed of the photo diode and the photo gate is applied to receive the light emitted from the light source. The sensitivity is changed via the operation of controlling the gate voltage of the photo gate. Moreover, the variance of the potential is read many times. The characteristic of the potentials under different conditions in different times having the same dark current and fixed pattern noise is utilized. The dark current and the fixed pattern noise can be eliminated by calculating their difference. Higher sensitivity in low illumination and lower sensitivity in high illumination can be obtained by calculating their summation, so as to increase the dynamic range.

Abstract: A complementary metal-oxide-semiconductor image sensor structure and associated layout method. A gate polysilicon layer of a reset transistor isolates the illumination region of an optical diode from field oxide layer corners of the image sensor so that current leaks between the illumination region and field oxide layer corners are minimized. Each side of the polysilicon layer also extends to and connects with a neighboring polysilicon layer. This expands the illumination region and increases fill factor of the layout.

Abstract: The present invention provides a process for determining the spacing between a heater and a showerhead. First, at least one variable capacitor is placed between the heater and the showerhead, such that the spacing between the heater and the showerhead is in a predetermined relationship to the capacitance of the variable capacitor. Then, the capacitance of the variable capacitor is measured, and the spacing between the heater and the showerhead is converted from the capacitance. The determination process of the present invention can be conducted at high temperature above 350° C., and the spacing can be determined without opening the deposition chamber. This makes the entire process very convenient and the cost can be saved.
