Abstract: A personal care article includes a resiliently stretchable outer cover. In a first embodiment, a first zone of the outer cover is embossed forming a pattern of embossments providing a first set of desired properties pertaining to stretch of a portion of the outer cover. A second zone of the outer cover is not modified to provide the first set of properties and thus has different stretch properties than the first zone. In a second embodiment, a first panel is secured to a resiliently extensible second panel. A first zone of the second panel can have a pattern of embossments securing the second panel to the first panel. The embossments cause the first zone to have different stretch properties than a second zone of the second panel that is not embossed thereby to impart the set of stretch properties. In a third embodiment the second panel is pre-stretched to a predetermined degree of elongation before securement to the first panel.

Abstract: A tampon for feminine hygiene having an absorbent core and a cover disposed around the core which is permeable to body fluids, the cover being provided with flexible barrier strips which are spreadable from the tampon surface.

Abstract: This invention relates to a recording node for receiving energy-related consumption meter data, for calculating consumption amount and consumption rate, and for storing such information. The invention further relates to networks into which the recording node is incorporated, or which can otherwise be accessed by the recording node. The recording node receives signals from a meter and calculates a current consumption rate value and a predicted consumption value for a time interval. At the end of the time interval, values calculated for the interval are stored in memory in the recording node and the recording node resets and begins calculating values for the next time interval. Price data may be received at the recording node from an external source, over a network, such as a distributed network, which includes the recording node. Consumption values and price data stored in the recording node are available to other nodes in the network. The network preferably does not include a central processor.

Abstract: This invention pertains to metal-air electrochemical cells wherein one or more air entry ports is located in the bottom of the cathode can, to provide for entry of oxygen-rich air into the cathode can, where the oxygen participates in the chemical reaction whereby the cell produces electrical energy. In this invention, multiple small air entry ports are provided. Generally, the use of multiple ports distributed over the bottom of the cathode can, opposite the reaction surface of the cathode assembly, while not increasing the overall open area of the ports, results in an increase in the ratio of the cell limiting current to the rate at which moisture is lost from the cell. Accordingly, moisture loss as a function of electrical energy produced, is reduced.
