Abstract: A device providing automatic control of temperature for an environment of a working station includes an air box, a baffle member, and a driving assembly. The air box is coupled to a machine defining a working space which the working station is in. The air box defines an opening. The opening allows cooling air to be introduced into the working space. The baffle member is slidably coupled to the air box at the opening. The driving assembly coupled to the baffle member drives the baffle member to cover the opening completely, to cover the opening partially, or to leave the opening uncovered in accordance with a difference between a current temperature of the working space and a desired target temperature of the working space. A related system and method are also disclosed.

Abstract: A camera-testing box for testing optical properties of an image-capturing device includes a box body, a light source, a photographic film, a mask, and a base. The light source is disposed inside the light-free box body. The photographic film is disposed on a side of the light source inside the box body. The mask is disposed on a side of the photographic film away from or facing the light source, and the mask includes a transparent area and a shielding area to reduce flare-causing light reflected by screws and other extraneous objects in the camera-testing box. The base is disposed inside the box body, and on a side of the mask away from the light source. The base supports the to-be-tested image-capturing device.

Abstract: A system for testing linear displacement of multiple linear motors simultaneously under various signals and electrical power supplies includes a testing device, a first processing device, and a second processing device. The first processing device outputs a first start signal to a plurality of first motors to control operation of the plurality of first motors. The second processing device receives a test start signal output by the first processing device, and outputs a first test trigger signal to the test device according to the test start signal. The testing device receives the first test trigger signal, and measures displacements of the moving end of the first motor according to the first test trigger signal.

Abstract: A test device for a lens module in respect of visible light and in respect of infrared light includes a test fixture and a display able to show both types of light in images captured.

Abstract: A multi-distance testing device includes a testing machine supporting a to-be-tested component, a first guide rail located on one side of the testing machine, a mobile platform connected to the first guide rail and capable to slide back and forth on the first guide rail, a fixing frame fixed on the mobile platform, a display screen fixed on the fixing frame and displaying test charts, a relay lens located between the display screen and the testing machine, and a control system electrically connected or signal connected to the display screen. The relay lens shortens a test distance to construct an infinite test distance in a limited space. The control system drives the mobile platform to move to the first designated position and controls the display screen to switch and display different test charts according to the distance between the display screen and the testing machine.

Abstract: A method of inspecting and controlling applied to a process of a testing a camera for correct color temperature in image-capturing includes: obtaining a first device identifier of light sources; obtaining a second device identifier of control devices; wherein each control device governs the opening or closing of a light source; associating the first device identifiers with each second device identifier, and generating a binding list; obtaining the second device identifier corresponding to a camera device; comparing the second device identifier corresponding to the camera device with the binding list, and recording the corresponding first device identifiers; wherein the camera device takes pictures under the light source corresponding to the first device identifiers to obtain image for analysis and analyzing whether image-capturing function of the camera is normal. A computer device and a storage medium for performing the above-described method are also disclosed.
