Patents by Inventor Theodore Liber

Theodore Liber has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20050103130
    Abstract: The subject invention is directed to methods, processes and decisions on test outcomes for testing for faulty, therefor dangerous, performance of zero speed indicators that are used to control the opening of barriers guarding moving machine components. The indicators may be tested by removing them from the components during operation without shutting down production or in certain situations the indicators may be tested during the run down phase of the components caused by machine stop initiations. The tests allow to anticipate and hence prevent hazardous opening of barriers due to a faulty zero speed indication. Additionally, the invention is directed to testing of the insertion of motion interference devices in conjunction with zero speed indicators, both of which must perform correctly in order to permit the unlocking and opening of the protective barrier. There are included various exemplary devices for effecting the testing function.

  • Patent number: 5870317
    Abstract: This invention relates to a novel process with attendant methods and apparatus for testing interlocks on machine barrier guards or equivalent safeguards. The process simulates the breaching of the interlocked safeguard to test the interlock without shutting down the machine operation. Failed interlocks are identified and their status warned against. Furthermore, the associated barrier guards may be physically locked to prevent access to their protected space while allowing normal machine operations until maintenance is practical. The testing process makes possible the reliable interlocking of fixed guards and may be automated to prevent bypassing or sabotage of interlocked safeguarding systems.

  • Patent number: 5755357
    Abstract: A single, traveling actuator services multiple medication dispensing carousels to selectively dispense medication. The traveling actuator carries a tray that receives the dispensed medication. The tray flips to discharge the medication for patient use. The single actuator simplifies operation and reduces drop distance, thereby leading to a compact, low profile assembly.

  • Patent number: 5207642
    Abstract: An improved multiple fluid delivery system usable for the delivery of intravenous fluids to a patient from a plurality of fluid sources includes flexible tubing members for coupling the sources to a fluid junction member. The fluid junction member, wherein little or no interfluid mixing occurs, is coupled by an output conduit to a controllable pump. Output from the pump, via a further fluid flow conduit, can be coupled to the patient's catheter. The system can multiplex a plurality of different fluids. Spaced apart sequences of fluid quanta are injected into the output conduit from the fluid flow junction. The fluids are either mixed, or not, in the output conduit as desired. Operator interaction and control of the system can occur either through a display screen or by means of a bar code sensor. Hard copy records can be provided of fluid flow delivery schedules or other related information.
