  • Publication number: 20180049837
    Abstract: A smart probe for use during an implantation procedure to provide a desired spacing between the implanted device and a body part while measuring the pressure exerted by the implanted device on the body part to ensure that the implanted device incorporates a desired tension, and thereby a desired pressure, on the body part. Also, a procedure for using the smart probe during the implantation procedure is disclosed.

  • Publication number: 20140342342
    Abstract: One aspect of the present disclosure relates to a system that can provide user-centric training. The system can include a touch screen that can be configured to receive a touch input from a user. The system can also include a non-transitory memory that stores instructions and a processor that can be configured to execute the instructions to at least: receive the touch input (that corresponds to a first node of a concept map related to a question) from the user in response to the question; create a user generated concept map based on a connection between the first node and a second node of the concept map related to the question; and score the touch input based on the connection in response to the question.

  • Patent number: 7343796
    Abstract: A microvalve sensor for sensing fluid flow therethrough and generating an electrical signal indicative thereof comprises: a housing connectable inline with a fluid passageway; a microvalve disposed in the housing to permit fluid to flow unidirectionally through the housing, the microvalve including: a substrate; an insulating layer disposed over the substrate, the substrate and insulating layer including an orifice to accommodate fluid flow through the housing; and a diaphragm element disposed over the insulating layer, the diaphragm element including: a solid center portion having an area sufficient to cover the orifice, and an outer portion surrounding the center portion having a plurality of apertures for passing fluid from the orifice through the housing, the outer portion being affixed to the insulating layer around a periphery thereof, the diaphragm element and substrate forming opposite plates of a capacitor having a capacitance which changes with fluid flow through the housing; and a circuit coupled a

  • Patent number: 5906676
    Abstract: An apparatus and method of reclaiming particles of powder material from a powder spray system (100) having an inlet passageway (190) of a collection subsystem (104) in fluid communication with an interior of a spray booth (108). An airflow conduit (250) extends between a trough (140) located under a conveyor belt (130) which in turn is located below the spray booth (108) and the inlet passageway (190) of the collection subsystem (104). Airflow through the airflow conduit (250) is augmented by a compressed air injector (280) disposed in the airflow conduit (250) and oriented so that it ejects compressed air in the direction of the inlet passageway (190). In this manner, particulate matter (overspray) settling in the trough (140) becomes entrained in an airstream (252) flowing into the collection subsystem (104). The collection subsystem (104) suitably includes a cyclone separator (170) and a filter stack (200).
