  • Patent number: 8492162
    Abstract: An electronic system for tracking and monitoring articles to be subjected to a sterilization cycle is disclosed. The method uses a sterilization indicator and electronically links sterilization information with the articles subjected to the sterilization process. The indicator allows a sterilization cycle to be monitored without the need for a user to subjectively distinguish between color, quality or intensity of display patterns.

  • Publication number: 20090313071
    Abstract: An automated system for management of information and distribution of materials associated with sterilization procedures includes a network server and client computers that communicate via a computer network. The client computers are distributed among sterilization facilities that require sterilization services. The network server exchanges a variety of information with the sterilization facilities. In response to information from client computers, the network server may trigger distribution of materials to sterilization facilities, and generates reports for record-keeping or cost-accounting purposes. The information distributed by the network server may pertain to the operation, maintenance and control of sterilization equipment, characteristics and capabilities of sterilization materials, and expert technical advice.

  • Patent number: 7122150
    Abstract: A system for determining the efficacy of a sterilization process and communicating that determination to a remote device. The system includes a sterilization sensor and a reader adapted to receive that sterilization sensor. The sterilization sensor has an indicator that undergoes a predetermined optical change when exposed to a sterilization process. The reader has an illumination source for illuminating the sterilization sensor, a color sensor for evaluating the condition of the illuminated sterilization sensor, and an interpretation circuit for interpreting the output of the color sensor to determine whether the optical change has taken place. The reader also has a communication circuit for communicating data from the interpretation circuit to the remote device. In the preferred embodiments, the sterilization sensor is disposable and the reader is reusable.

  • Patent number: 7039990
    Abstract: Apparatus and methods for stretching one or more zones of a web are disclosed. Webs including stretched or activated zones are also disclosed. Each of the zones in the web is stretched in the cross-web direction, i.e., the direction transverse to the down-web direction. The stretching it can be performed continuously as the web is advancing through the apparatus in the down-web direction. The stretching can occur in the absence of physical contact with the stretched zone of the web. Strain induced on the stretched zones can be introduced gradually over a stretch distance. The strain may increase at a linear rate. The stretching methods and apparatus may be used to activate an elastic zone or zones within a web.
