A sign assembly including a flip placard assembly, a placard support assembly, a flip assembly, hinges, flip placards, and placard supports such that the flip placards can be interchanged. A clear cover connected to a bottom placard support creating a compartment for additional messaging. A method of quickly interchanging flip placards for use in a nuclear facility or hazardous environment.

A display apparatus includes a display including a front surface configured to display an image and a rear surface provided with a mounting groove. The display apparatus further includes a rotation module including at least one body that is configured to couple to the display by being inserted into the mounting groove, the rotation module further including a drive motor configured to provide a driving force to rotate the display about an axis perpendicular to the front surface and the rear surface of the display. The display apparatus further includes a bracket configured to be mounted on a stand or a wall and to which the rotation module is coupled. The display and the rotation module are configured to lock together by the display and the rotation module being coupled.

A defense mobile device for securing a door during shelter-in-place situations. The device includes wheels rendering it mobile and stops that, when actuated, hold the device stationary. A panel has a ballistic core that resists bullets, a front face, an opening, and a cover positioned over the opening to overlay and enclose a door knob protruding through the opening. The front face forms, or has affixed to it, a writing surface. The panel pivots between a plurality of angled positions to facilitate writing and an upright position flat against the door. A locking rod, rotatably connected to the panel, pushes and pulls the panel between its angled positions and its upright position. A lever-locking mechanism or a twist-lock mechanism secures the device in place against or within a door frame and against the door.

An illuminated sign for use in a vehicle wash system, including a base, an upright member extending from the base and having an upper portion and a lower portion, and a head portion connected to the upper portion of the upright member. The illuminated sign includes at least one light source having a first mode and a second mode. The first mode is associated with a first group of vehicle wash services for treating an exterior of a vehicle. The second mode is associated with a second group of vehicle wash services for treating an exterior of a vehicle. The sign includes a sign controller in communication with the at least one light source. The sign controller is configured to enable the first mode in response to detecting a selection of the first group of vehicle wash services. The sign controller is also configured to enable the second mode in response to detecting a selection of the second group of vehicle wash services.

A low drag outdoor media façade display for mounting on a structure susceptible to instability when exposed to strong winds, having an array of radiating elements thinly dispersed about the façade area, held by an array of thin suspension elements, the elements are spaced apart leaving gaps, such that the total surface area of the elements is smaller than the total area of the façade display. A tilting mechanism, active or passive, is operational for tilting the façade display or at least one element thereof. The passive mechanism allows free tilt in response to wind blow, and the elements may include tails. The active mechanism is operational for altering wind load drag profile of the façade display to accommodate wind conditions. The display may be inflatable or collapsible sail-like. A display featuring a liquid spray curtain for refracting or reflecting light projections is a further measure for reducing wind load.

A sign including a frame configured to support a sign face. The frame includes a first section and a second section. The sign also includes a first bracket coupled to the frame, the first bracket defines a longitudinal axis, and a second bracket coupled to the first bracket. The second bracket is rotatable with respect to the first bracket, and the second bracket is movable between a first position in which the second bracket extends transverse to the longitudinal axis and a second position in which the second bracket extends along the longitudinal axis. The sign also includes a light bar coupled to the second bracket. The second section is movable with respect to the first section between an installed position and a collapsed position.

A bracket system for mounting a sign to a vehicle is described. The bracket system may be designed to attach to the hinges and lock rods of the left and right doors of a tractor trailer. The system may include a sign frame that includes a left horizontal bracket(s) that is connected to the left hinge(s) of the left door, a right horizontal bracket(s) that is connected to the right hinge(s) of the right door, a left lock rod bracket(s) connected to the left lock rod, and a right lock rod bracket(s) connected to the right lock rod. Left sign and right sign panels may be connected to the sign frame. The sign panels, the horizontal brackets and the lock rod brackets may be configured to swing open and closed with the respective doors. A multi-part clamp may be used to attach the lock rod brackets to the lock rods.
