  • Patent number: 8858494
    Abstract: A system and method for preventing an undesirable reverse rotation of an infusion pump assembly. The infusion pump motor includes a roller assembly, a coil, a rotor, a rotor position sensor, and a controller. The rotor is in communication with the coil, and the rotor is rotationally coupled to a roller assembly. If the pump is in not pumping, then the system monitors for reverse rotation of the pump, and if reverse rotation of the pump is detected, energizes the coil in a manner that holds the rotor in place. The system may also activate an indicator if reverse rotation is detected.

  • Patent number: 7722698
    Abstract: A method of determining the purity of oxygen present in an oxygen-enriched gas produced from an oxygen delivery system is disclosed. The oxygen delivery system includes at least one sieve bed having a nitrogen-adsorbing material disposed therein and configured to adsorb nitrogen from a feed gas introduced into the at least two sieve beds via a pressure-swing adsorption cycle. The method includes determining a quantity of nitrogen adsorbed by the nitrogen-adsorbing material by inferring an effective volume of the at least one sieve bed based on a pressure change of the at least one sieve bed.

  • Patent number: 7405538
    Abstract: A method of charging a NiMH or NiCd battery such that charging does not occupy a substantial amount of time and such that the operating temperature of the battery is reduced during the lifetime of the battery, thereby extending the life of the battery. This invention is a method of charging that is accomplished using a temperature differential method to continuously regulate the rate of charge injected into the battery. An amplifier is used to amplify the difference in temperature between one or more cases in which the battery is contained and ambient temperature. In this method, the greater the difference in temperature, the lower the charging current is injected into the battery. The method of charging may be incorporated into uninterruptible power supply equipment.

  • Publication number: 20080084049
    Abstract: A new type of inflatable cushion system in disclosed that does not need an external wrapper (or other similar feature) to maintain the cushion in the rolled configuration prior to deployment. Rather, a spot adhesive is added to an inflatable cushion as the mechanism for holding the cushion in the rolled configuration. The inflatable cushion has an inflatable region and a top edge. The spot adhesive is positioned on the top edge. This inflatable region of the inflatable cushion will also include an engagement area. In generally, the spot adhesive will engage the engagement area and holds the inflatable cushion in a rolled configuration prior to deployment. The adhesive may be double sided tape that is affixed directly to the cushion. The adhesive may also be a hook and loop fastener system, such as “Velcro” or any other suitable fastener.
