Abstract: A circuit protection device includes a first temperature sensitive resistor, a second temperature sensitive resistor, an electrically insulating multilayer, a first and second electrode layer, and at least one external electrode. The first temperature sensitive resistor and the second temperature sensitive resistor are electrically connected in parallel, and have a first upper electrically conductive layer and a second lower electrically conductive layer, respectively. The electrically insulating multilayer includes an upper insulating layer, a middle insulating layer, and a lower insulating layer. The upper insulating layer is between the first upper electrically conductive layer and the first electrode layer. The middle layer is laminated between the first temperature sensitive resistor and the second temperature sensitive resistor. The lower insulating layer is between the second lower electrically conductive layer and the second electrode layer.

Abstract: Aligning a detection or transmission module with an optical lens assembly on a chassis in a LiDAR system may include a transparent mounting block, for example a glass transparent mounting block. A first portion of adhesive may be applied between the transparent mounting block and the chassis, and a second portion of adhesive may be between the transparent mounting block and the detection or transmission module. Prior to curing the portions of adhesive, the detection and/or transmission module may be optically aligned with the optical lens assembly so that a path of a laser beam emitted from a laser module of the transmission module is oriented with an optical path in the optical lens assembly to a detection sensor of the detection module. The transparent mounting block allows for visual inspection of the cured first and second portions of adhesive through the transparent mounting block.

Abstract: Embodiments of the disclosure provide an interface module for a LiDAR assembly. The interface module includes a printed circuit board (PCB) and a first connector interface disposed on the PCB. The first connector interface is configured to be connectable to a laser emitter of the LiDAR assembly. The interface module further includes a second connector interface disposed on the PCB and a third connector interface disposed on the PCB. The second connector interface is configured to be connectable to a receiver of the LiDAR assembly and the third connector interface is configured to be connectable to a control module configured to control the operation of the laser emitter and the receiver. The interface module also includes a bracket where the PCB is affixed to. The interface module is positioned to a lateral face of the LiDAR assembly through the bracket.

Abstract: Embodiments of the disclosure provide an integrated transmitter-receiver module for a LiDAR assembly. The integrated transmitter-receiver module includes a laser emitter configured to emit optical signals to an environment surrounding the LiDAR assembly. The integrated transmitter-receiver module also includes a receiver configured to detect returned optical signals from the environment. The laser emitter and the receiver are pre-aligned to focus the returned optical signal on one or more detectors of the receiver and are disposed on a shared base wherein the shared base is configured to assemble the integrated transmitter-receiver module to the LiDAR assembly.

Abstract: A switch comprises a seat, a key body, a first elastomer, a second elastomer, and a cover. A neck portion of the key body has an assembling portion, and the assembling portion is installed with the light generator. As the key body is pushed, the second elastomer will contact the cover; the positive (negative) power connected to a conductive piece will be transferred to the positive (negative) end of the light generator. At the same time, the first elastomer contacts internal wires of a first receiving portion so as to provide negative (positive) power to the negative (positive) ends of the light generator. Then, electric signals are outputted and the light generator lights up.

Abstract: A method for reducing a gate length bias is disclosed. The method utilizes an additional blanket ion implantation process to adjust the etching property of the undoped conductive layer. According to the present invention, a polysilicon layer is used to form NMOS and PMOS gate electrodes so that the gate length bias between the NMOS gate electrodes and the PMOS gate electrodes can be effectively reduced.

Abstract: A game pad of the present invention is electrically connected to a mainframe through an interface for controlling a game software executed in the mainframe. The game pad includes a scanning circuit electrically which is electrically connected to a central controller, a push-button type direction control circuit, an induction type direction control circuit, a programmable push pad circuit and a gad control circuit. The scanning circuit is controlled by the central controller to scan the above-stated circuits, thereby selecting one of them. The induction type direction control circuit includes a sense device which consists of sensors. According to a relative position with a reference direction, each sensor generates and transmits a direction control signal to the sense device to thereby make the central controller read and scan the moving direction of the sense device. The selecting device is electrically coupled to the central controller for selecting a mode of direction control.

Abstract: A waterproof switch device is for use with an elongated actuator in a water containing chamber, and includes a top cover wall spaced apart from the chamber and having a bore for movement of the actuator in response to a reach of a predetermined water level. A rear wall and two engaging walls are integrally formed with the top cover wall to form an inner major surface. A groove forming wall is integrally formed with and extends from the inner major surface, and is spaced apart from the top cover wall so as to define an inserting groove therebetween. A switch body is mounted on and is spaced apart from the inner major surface, and has an actuated stud to make a switching action when depressed. A lever includes an actuating end disposed between the groove forming wall and the actuated stud, and a force transmitting end disposed under and moved downward by the elongated actuator to cause the actuating end to depress the actuated stud.
