Abstract: A height indicator as provided on an articulating support arm at a workstation. The height indicator has a scale and a needle moves up and down the scale as a platform of the support arm is raised or lowered relative to a base.

Abstract: An adjustable keyboard support mechanism includes a mounting bracket for attachment to a support surface, a platform for supporting a keyboard thereon, a support arm operably connected to the mounting bracket and the platform, and a locking mechanism for restricting height adjustment of the platform with respect to the support surface. The locking mechanism includes a center arm pivotable with respect to the platform and slidable with respect to the mounting bracket, a plurality of frictional members sandwiching and frictionally engaging the center arm, thereby restricting the sliding movement of the center arm with respect to the mounting bracket, and a wedge assembly actuable by pivoting movement of the platform and engageable with the frictional members to both restrict and allow height adjustment of the platform relative to the support surface.

Abstract: A storage and security case for a personal computer comprises a housing with fold over side platforms, which operate a mechanism to raise and lower a support platform within the case to cover a personal computer stored within the case or expose the personal computer. The side platforms provide additional functions such as a storage tray for various materials and a mouse platform.

Abstract: An improved brake and tilt adjustment control mechanism for a keyboard support platform includes a telescoping shaft connect between the keyboard platform and a housing supported on linkage arms that support the platform and connected the platform to a desk or support surface. The shaft is engaged by an encircling coil spring retained in the housing to lock the mechanism. Flexing the spring release locking mechanism and permits adjustment of the tilt or attitude of the keyboard platform to the linkage arms.

Abstract: A keyboard support arm assembly includes the keyboard platform having a planar surface and upon which is projected a virtual keyboard the projection being by means of a projection device having virtual image capability and having the capability of reading on a site-by-site basis the position and existence of or status of any manual digit input signal.
