Abstract: An inflatable down hole bag includes an inflatable body for holding an inflation fluid and a container for holding one or more substances. The container is disposed inside of the inflatable body and includes a closure for keeping the one or more substances in the container when the closure is in an inoperative state. The closure also releases the one or more substances from the container when the closure is in an operative state. Release of a substance causes an inflation fluid producing reaction within the inflatable body, thereby inflating the inflatable body. The container includes at least two separated chambers. Each chamber holds a respective one of the substances. The closure includes a stopper for closing a respective opening to one of the chambers. The closure further includes an actuator for removing each stopper from the respective opening so as to release each substance from each respective chamber.

Abstract: A waterfall sink has a series of contours as elevationally spaced apart upper steps separated by vertically extending walls extending from an upper surface of to a bottom surface to form a partial sink bowl. The bottom surface directs fluid from the partial sink bowl off a side edge to then downwardly proceed to a drain below the bottom surface. Many embodiments have a channel extending into a side surface along the side which receives the fluid from the partial bowl. Some embodiments have side steps which coordinate with the upper steps to form a continuous partial perimeter. Water from a faucet directed into the partial bowl proceeds above the bottom surface and over the side edge downwardly like a waterfall.

Abstract: A composite thermoplastic liner for use as a moisture barrier comprises a hollow tubular body made from a woven composite thermoplastic material configured to substantially block the ingress of moisture; and an opening at one end of the hollow tubular body for intake into the hollow of the hollow tubular body. In one aspect a welded closed opposite end forms a base configured to substantially block the ingress of moisture external to the hollow tubular body. In another aspect the woven composite thermoplastic material comprises an electrically conductive additive. In another aspect there is a gusset in at least one side of the hollow tubular body. The hollow tubular body is able to be flattened with the respective gussets formed from folds of the hollow tubular body, such that in the flattened state the tube is more readily stored in a narrow form, but is expandable when the gusset is unfolded.

Abstract: An object is to provide programs for reliable predictions of the day of ovulation. A process is executed in a program for predicting a day of ovulation on a computer, the process including calculating a predicted ovulation day data corresponding to a particular menstrual cycle by applying the particular menstrual cycle to a relationship between a period between a menstrual day and a day of ovulation and an average length of a menstrual cycle, the relationship being estimated based on data of a plurality of persons which have been previously obtained.

Abstract: In various embodiments, the disclosed wireless sensors comprise chemically-sensitive conductor traces that respond to variations in the polymer surrounding the sensors due to the change in proximity of the chemicals stored within the polymer vessels (e.g., degradation of the structural integrity of the polymer vessel). The sensors may generally be installed at the interface between the corrosion barrier and the structural layers of a polymer vessel comprising any FRP, PTFE, plastic, or other polymers. As the chemical stored within the polymer vessel degrades or permeates the corrosion barrier, the impedance measured by the sensor, in one embodiment, changes, which signals a change in the structural integrity of the polymer in which the sensor is embedded.
