The present invention relates to a display device comprising a mounting board and a display panel mounted on the mounting board and comprising a plurality of display modules arranged in an array, and further comprising a control module and a plurality of driving modules corresponding to the display modules. The control module is capable of controlling the driving modules to drive the corresponding display modules to extend. When the display device is powered on, the control module is electrically coupled to the driving module such that the driving module receives a signal from the control module and controls the display module to extend in response to the signal; when the driving module is started, the corresponding display module moves along with the driving module and automatically extends, facilitating the maintenance of the display device.

A transfer system for diagnosing a vehicle is provided. The system includes a conveyor that moves the vehicle and a transfer unit that is disposed an input or an output side of the conveyor to move the vehicle into a diagnosing region for vehicle diagnosis. The transfer unit includes a guide rail disposed in both sides of the diagnosing region and a moving body disposed along the guide rail. Swing arms are rotatably connected with a forward and a rear side of the moving body and are concentrated inward to be disposed forward and rearward of a lower portion of a tire. Free rollers are rotatably disposed at each swing arm concentrated inward to clamp the tire. A swing arm driving unit provides a driving force so that the swing arms are concentrated inward or unfolded outward. A moving body moving unit moves the moving body along the guide rail.

An ergonomic apparatus for handling a hinged lid that reduces force required to open the hinged lid and bending by a user, maintains the lid in an open position to prevent accidental closure of the lid, and assists with closing the lid. The apparatus has a horizontal member with an attachment means for removably coupling the apparatus to the hinged lid, a vertical member extending from a proximal end of the horizontal member, and a handle in operable communication with the vertical member. The vertical member and handle are configured relative to the horizontal member such that when the vertical member is positioned on a flat surface, the handle is raised above the flat surface by about 10 to 25 and the hinged lid is maintained in an open position having an angle greater than 90 relative to an opening the hinged lid was covering.

A modular jack head isolator apparatus offers a buffer between a pipe-jack stand head and a workpiece such as piping to mitigate potential damages facilitated therebetween. The apparatus uses major planar members joined by a vertex and hooks to situate upon the pipe-jack stand head by sliding the hooks thereon. The apparatus offers a telescoping member for each of the major planar members, fitting onto a wider pipe-jack stand head. A locking hinge can modularly alter the inclination between the first and second major planar members to suit any angle of the pipe-jack stand head or other V-groove implement. Further, the apparatus uses magnets to attract to the metallic pipe-jack stand and resist slipping therefrom. Thus, the apparatus addresses the immediate damage that transpires between the piping workpiece and the pipe-jack stand head while providing various features to make the apparatus substantially universal.
