Abstract: Fluid sensing devices including a layer of fluid absorption and distribution material are provided. The layer includes a porous fibrous nonwoven matrix for absorbing fluid from the object to the first major surface of the layer and laterally distributing the absorbed fluid throughout the layer and to a second major surface of the layer opposite the first major surface. Hydration sensors are disposed on the second major surface of the layer to measure a hydration level.

Abstract: According to one embodiment, a method of making an abrasive layer on a backing is disclosed. The method can comprise: providing dispensable magnetizable abrasive particles and a distribution tool, wherein the distribution tool is configured to receive the magnetizable abrasive particles therein, and wherein the distribution tool is configured to impart at least one of a predetermined orientation and alignment of the magnetizable abrasive particles, positioning a backing adjacent to the distribution tool and spaced therefrom by a gap, applying a magnetic field to at least the backing and a portion of the gap between the backing and the distribution tool, and transferring the magnetizable abrasive particles from the distribution tool to a first major surface of the backing, wherein the magnetic field is applied during the transfer of the magnetizable abrasive particles.

Abstract: Flexible, stretchable RFID tags are formed by a pocket that is formed from one or more substrates and layers of adhesive, and an electronic circuit that is located within this pocket. The RFID tags can include a stretchable substrate and an electronic circuit attached to the stretchable substrate by one or a finite number of discrete spaced apart attachment locations. When the pocket is formed by relatively thick adhesive layers adhering together one or more flexible substrates to form an internal cavity, the electronic circuit is located within this cavity and either is not adhered to any of the substrates of the cavity, and is free to move about within the cavity, or the electronic circuit can be attached to a substrate by a thin layer of adhesive.

Abstract: A data communication apparatus, system, and method are described. The data communication system comprises a transceiver disposed on an entrance port to an enclosure, such as an underground enclosure. The transceiver includes a housing, the housing mountable to the entrance port, wherein the transceiver is configured to communicate with a network outside of the underground enclosure. The data communication system also includes a monitoring device disposed in the underground enclosure that provides data related to a real-time condition within the underground enclosure. The data communication system also includes a sensor analytics unit to process the data from the monitoring device/sensor and generate a processed data signal and to communicate the processed data signal to the transceiver.

Abstract: A system for use in wirelessly monitoring a pipeline such as a natural gas pipe. The system includes a locator configured to wirelessly transmit power and a subsoil sensor marker located adjacent the pipe and configured to wirelessly communicate with the locator. The sensor marker includes a microcontroller, a memory module, a sensor configured to sense the presence of a gas, and a power module. The power module is configured to harvest a sufficient amount of the power wirelessly transmitted from the locator in order to operate the microcontroller to take a measurement via the sensor, save the measurement in the memory module, and wirelessly transmit the measurement to the locator.

Abstract: A shoe degradation sensor assembly includes a first sensor disposed in or proximate to a material layer of a shoe between a foot space and an outer surface of the shoe, and an electrical contact assembly operable to removably electrically connect the shoe degradation sensor assembly to a reader. The material layer changes in at least one physical property with degradation to the shoe, and the first sensor is configured to indicate the changing physical property of the material layer thereby indicating a degree of degradation to the shoe.
