A system, as an engine with a crankcase containing oil or a fluid mixed with oil, has a reservoir containing liquid that extends up to a level of the fluid. A dipstick support structure supports a dipstick on it so that the dipstick extends into the fluid past the level of the fluid, and so that the dipstick is manually removable from the dipstick support structure by a user. An electrical system is connected with the dipstick, and the electrical system electrically senses the level of the fluid based on an electrical characteristic of the dipstick that varies with the varying level of the fluid when the dipstick extends into it. The electrical characteristic may be capacitance of the dipstick detected by sequential charging and discharging of the dipstick to produce a square wave electrical signal the frequency of which corresponds to the level of fluid.

Dipstick and electronic fluid level sensor

A file cabinet providing access to files from substantially all sides, and having at least one rotatable tier. Each tier includes a carrousel file support having a plurality of radially extending arms. Mounted to the outer terminus of each arm is a pivot arm assembly, each configured to rotate about a vertical axis between a retracted position and an extended position. Each pivot arm assembly is adapted to suspend a file container thereon to provide detachable storage.

Carrousel file

A file cabinet providing access to files from substantially all sides, and having one or more rotatable tiers, each tier containing a plurality of file containers. Each tier includes a central carrousel having a plurality of radially extending arms. Mounted to the outer terminus of each arm is a file support assembly, each configured to rotate about a vertical axis between a retracted position and an extended position. Each file support assembly is adapted to suspend a file container thereon to provide detachable storage. The detachable file containers each include a box having an upper frame which suspends the container from the file support assemblies. A top may be provided to close each container in a secure manner to protect the container's contents.
