A system for controlling a traffic warning triangle to avoid obstacles when moving towards a placement location includes a depth calculating module, a determining module, and a control module. The traffic warning triangle includes a binocular camera to capture real-time images of a path or road in front of the triangle. The depth calculating module compares and analyzes first and second images, captured at the same time, to calculate depth information between the binocular camera and an obstacle. The determining module determines whether the depth information is less than a threshold value. The control module adjusts a moving direction of the mobile warning triangle to avoid the obstacle in response to the depth information being less than the threshold value, according to a process. An obstacle avoidance method of the mobile warning triangle is also provided.

A multi-position illuminated signage panel comprising a mounting assembly anchored to a vehicle, a display assembly, and an intermediate assembly. The display assembly comprises an illumination panel and a sign insert for displaying a visual element. The intermediate assembly comprises a control unit for controlling the operation of the illumination panel, the control unit having a solar panel, rechargeable battery, motion sensor, light sensor, and control module. The illumination panel is positioned behind the sign insert and produces a back-light effect by emitting light which passes through the sign insert. The illumination panel can be activated when the motion sensor detects the vehicle's motion, and deactivated when the photosensor is exposed to light. The display assembly is hingedly connected to the intermediate assembly, which is in turn hingedly connected to the mounting assembly, allowing the multi-position signage panel to be configured in multiple display positions.

A placard with an image may be placed upon a rod such that a passenger of a vehicle may imagine interactions of the image with the changing surroundings of the vehicle. Ideally, the placard should be clear except of the image which may then appear on both sides of the placard. A hinged suction cup connection to the placard allows for reversibility of the placard and or the placard to continue being held on the window when in use. A tether may also be utilized to secure the placard to the rod.

A serving robot apparatus is disclosed. The serving robot apparatus includes a main body; a shelf horizontally supported by the main body; a first driving device configured to move the main body; a display comprising a front surface to display an image and a rear surface disposed to face a side surface of the main body; a link member comprising one end connected to the main body and other end connected to a rear surface of the display; and a second driving device configured to move the link member so that the display moves along the side surface of the main body.

The present invention discloses an electronic product and LOGO display method and system thereof, wherein, the LOGO display system comprises an IR emitting and sensing module, a LOGO projection module and a processing module. It emits an IR and detects an IR intensity reflected by a human body through the IR emitting and sensing module; then compares the IR intensity detected by the IR emitting and sensing module with a threshold through the processing module, controls the LOGO projection module to project the LOGO, when the IR intensity is larger than the threshold; it has achieved a personalized display for the LOGO, and attracted an attention from the user to the LOGO, which is more energy-saving and environment-friendly than the prior art of displaying the LOGO continuously after turning on the machine.

A display panel assembly includes a display panel including an array of LED (Light Emitting Diode) pixels, and includes a support assembly configured to hold the display panel near the rear window of the vehicle. In one embodiment, the support assembly for holding the display panel in the vehicle includes a first strap and a first hinge. The first hinge includes: a first flap having a first hole; a pivot; and a second flap having a second hole and a third hole. The first strap includes a fourth hole and a fifth hole located at a hinge end of the strap, and a sixth hole located at a cross beam end of the strap.

One embodiment of the present invention provides a display device from which a driver or a fellow passenger in a mobile body such as a vehicle can easily obtain desired information. One embodiment of the present invention is a display device including a display panel. The display panel is placed inside a mobile body including window glass. A film including a light-blocking layer is provided between the window glass and the display panel of the mobile body. By providing a driving unit controlling the display panel, the positional relationship between the window glass and the display panel is changed. Alternatively, by providing a driving unit controlling the film including the light-blocking layer, the positional relationship between the window glass and the film including the light-blocking layer is changed.

A method is provided for tracking and/or locating a delivery item transport equipment label. A delivery-item transport equipment label is scanned. At least one of a first identifier that is attached to a bracket or an RFID chip that is attached to the bracket is scanned to associate the delivery-item transport equipment label with the RFID chip. The RFID chip is scanned during use of a delivery-item transport equipment to which the bracket is attached. A location of the delivery-item transport equipment label is identified based on the scanning of the RFID chip.
