Abstract: A device for transporting strollers includes a base member having a plurality of compartments, a plurality of wheels for supporting the base member wherein two such wheels are mounted adjacent the rear portion and another wheel is pivotally mounted to the base member. A plurality of elongated straps are secured to the top surface and to a stroller positioned thereon respectively. The device further includes a mechanism for rotating at least two of the plurality of wheels and a hand-operable remote control unit for selectively transmitting RF signals to the rotating mechanism. The rotating mechanism includes a plurality of motors, at least one power source disposed within select ones of the plurality of compartments, a receiver for receiving the RF signals generated from the remote control, and a microprocessor electrically coupled to the receiver.

Abstract: A novel fault-tolerance technique for protecting against and correcting errors in packet data stream flow, preferably through not exclusively with closed ring sequential address generators and the like, through the use of pairs of independent but linked packet data flow paths enabling discarding of error data occurring in one path and substituting therefor corresponding correct data from the other path to enable continuation of the data stream flow without interruption and without error.

Abstract: Sensor assemblies, comprising one or more sensors for use in high-temperature environments such as an aircraft wing, include a thermally conductive retaining member in thermal communication with either the sensor or the environment surrounding the sensor. A housing assembly placed proximate to, and in thermal communication with, the retaining member defines a fluid passageway. During operation, fluid circulates through the housing to enhance the transfer of heat away from the sensor. Such heat transfer facilitates maintaining a sensor environment within the tolerance range of the sensor, thereby facilitating monitoring of the pressure fluctuation (or other sensor parameter) during operation of the aircraft.

Abstract: The present invention provides a method and apparatus for enabling a cluster of computers to appear as a single computer to host computers outside the cluster. A host computer communicates only with a gateway to access destination nodes and processes within the cluster. The gateway has at least one message switch which processes incoming and outgoing port type messages crossing the cluster boundary. This processing comprises examining certain information on the message headers and then changing some of this header information either to route an incoming message to the proper computer node, port and process or to make an outgoing message appear as if originated at the gateway node. The message switch uses a table to match incoming messages to a particular routing function which can be run to perform the changes necessary to correctly route different kinds of messages.

Abstract: The degree of saturation of a vapor in a chamber such as a curing oven is controlled by sensing the vapor dew point and varying the rate of removal of such vapor from the oven in response to a comparison of the sensed dew point with a predetermined dew point. This comparison may also be effected by comparing the difference between the actual dew point and oven temperature with a predetermined difference and controlling the rate of vapor removal in response to variations between the actual and predetermined differences. Alternately, a predetermined ratio between dew point and oven temperature may be maintained. By controlling the dew point of the vapor, i.e. degree of saturation, condensation in the oven is precluded while still permitting high solvent vapor concentrations which in turn facilitate recovery of solvent exhausted or removed from the oven.
