A system for dynamically projecting a logo onto a surface includes a light source, moveable lenses, and an actuator. The light source emits light toward the surface. The lenses are positioned with between the light source and the surface, with each lens having multiple transparent portions configured to permit some of the emitted light to pass through the lens in a corresponding light pattern. Each corresponding light pattern forms a different part of the logo. The actuator moves the lenses with respect to the emitted light in response to a control signal to thereby cause projection of the logo onto the surface. A vehicle includes a body having a door, road wheels in contact with a road surface, and the system which projects the logo onto the road surface proximate the door. The controller may be programmed to execute a method for projecting the logo.

This invention relates to the protection system for battery current collectors in cameras mounted on a gun, bow, or shooting device. More particularly, the present invention relates to the system of protecting the current collectors from fracture in a camera attached to a gun barrel or shooting device as a result of recoil and shock and vibration during shooting device discharge.

A sensor system comprising a housing, a movement apparatus to change an orientation of a directional sensor disposed inside the housing, and an indicator apparatus to present the orientation of the directional sensor to a viewer that is outside of the housing. The directional sensor may be a camera, and the indicator apparatus may indicate a field of view of the camera to the viewer that is outside of the housing.

A system including a drone having a projector to project an image from a projection origin. The drone also has a navigation unit to determine location information for the drone. A processor coupled to the drone includes a memory. Execution of programming by the processor configures the system to obtain a projection surface architecture for a projection surface. The projection surface architecture includes reference points that correspond to physical locations on the projection surface. Each reference point is associated with relationship data with respect to an architecture origin. The system also receives location information for the drone, adapts the relationship data responsive to change in the location information, adjusts the image using the adapted relationship data, and projects the adjusted image onto the projection surface.

A system is provided. The system includes a translucent display positioned such that a first face is a display face and that a second face is a projection face and at least one projector configured to project an image on the second face of the translucent display. The image is displayed on the first face. The system also includes at least one sensor configured to transmit a signal when triggered and a projector controller in communication with the at least one projector and the at least one sensor. The projector controller is programmed to receive a signal from the at least one sensor and instruct the at least one projector to project at least one image on the translucent display in response to the signal from the at least one sensor.

A lens driving device includes a lens carrier for maintaining a lens, a base for supporting the lens carrier, an first electromagnetic drive mechanism and an second electromagnetic drive mechanism which are mounted between the lens carrier and the base, and a front side spring component and a back side spring component which are connected with each other through connecting components. One of the front and back side spring components is connected with the lens carrier, the other of which is connected with the base. The lens driving device is difficult to damage when suffering from external force and is capable of playing the auto focus and shaking functions correction stably.

Provided are a projector playing control method, device, and computer storage medium, for addressing the problem in the prior art of inconvenient user operation caused by a display screen of the projector being used as an operation screen while a file is displayed on the operation screen. The projector control method comprises: when the projector receives a playing instruction, setting an icon corresponding to an application used to play the file as the content to be displayed on the operation screen of the projector, and displaying the icon, the icon being used to generate a control instruction according to the user operation, thus controlling the playing of the content outputted by a light source of the projector.

An autonomous travelling vehicle provided with an elevation apparatus on a chassis includes Wi-Fi antennas and cellular antennas that are columnar antennas and that are stood adjacent to an area for elevational motions of an elevation mechanism of the elevation apparatus.
