Abstract: An adjustable toilet footrest assembly has a main footrest and a height-adjusting accessory, wherein the height-adjusting accessory is removably attachable to the top of the main footrest and wherein the height-adjusting accessory is nestable to the underside of the main footrest when not in use.

Abstract: The present disclosure is directed to adjustable toilet footrests while using a toilet. In one example, an adjustable toilet footrest has a foot platform having at least two telescopic legs extending therefrom, wherein the telescopic legs have a locking mechanism that allows for the height of the platform to be selectively adjusted to a user's desire.

Abstract: The present disclosure is directed to inflatable toilet footrests while using a toilet. In one embodiment, an inflatable toilet footrest comprises a foot surface having a back concave curvature sized so as to conform to a toilet, a sidewall extending downwardly from the foot surface creating an airtight seal with the foot surface, a bottom portion connected to and creating an airtight seal with the sidewall, and an air valve.

Abstract: A mechanical page turner using a removable rack with space page turning bars operated by preloading the rack with pages of a musical score or the like, mounting the rack in the page turning apparatus and then moving the rack by a spiral rod driven by an electric motor from one portion of the apparatus to another.

Abstract: An automated system for rapidly and safely evacuating used fluid from the drain plug opening of a fluid receptacle and replenishing the fluid receptacle with fresh fluid through the same drain plug opening. The automated fluid changing system includes an evacuation means for withdrawing the used fluid from the drain plug opening, a dispensing means for dispensing fresh fluid into the fluid receptacle through the drain plug opening, valve means for controlling the flow of fluids into and out of the fluid receptacle, and electronic control means which is in communication with the valve means, the evacuation means, and the dispensing means for automatically directing each phase of the fluid changing procedure. The evacuation means includes a suction pump for applying a suction force to withdraw the used fluid. The dispenser means includes a pump for dispensing the fluid into the fluid receptacle under pressure.

Abstract: A fluid exchange apparatus for the transfer of fluids from a first containment area to a second containment area, including a total fluid reconciliation process, whereby the same amount of fluid transferred from the first containment area to the second containment area is replenished into the first containment area, or is replenished to a preset amount. The fluid exchanger includes an evacuation section having a vacuum pump therein, and a fill section. The fluid being vacated from the first containment area is transferred to the second containment area by vacuum pressure introduced into the first containment area. An air purge is used to drive fluid out of the fluid passages/filters into the first containment area. The pressure may be developed internally to the fluid exchange apparatus or externally thereto. CPU controlled electronics are utilized to measure, monitor, and control, via a user interface screen, the fluid exchange machine.

Abstract: A solid state control panel system utilizing optical coupling between a graphic control panel and a hand-held probe is disclosed. Separate light emitting control diodes and display diodes are utilized on the graphic panel. In response to a coded optical coupling between selected light emitting diodes on the panel and a light sensitive diode in the probe, various switching functions are performed. The system provides three different types of coding for each complete switching operation, namely, time coding, polarity, and pulse sequence coding. The probe includes means to inform the operator when proper optical coupling occurs; and is so constructed mechanically that it can be operated by pressure engagement with the panel, or as a gun. The system is structured to provide various types of switching functions, including the provision for selecting any one of a plurality of individual switches in its present state for display and control with each selected switch having a multiplicity of states.
