Abstract: A process for manufacturing a reinforced membrane-seal assembly includes: (i) providing a carrier material; (ii) providing a planar reinforcing component having one or more first regions including pores and a second region including pores, the first regions being patches and non-continuous and the second region surrounding the first regions and being continuous; (iii) depositing an ion-conducting component; (iv) drying the ion-conducting component; (v) depositing a seal component; (vi) drying the seal component (vii) removing the carrier material. In embodiments, ion-conducting component fills the pores in the first regions and seal component fills the pores in the second region; steps (ii), (iii) and (v) can be carried out in any order; step (iv) is carried out subsequent to step (iii); step (vi) is carried out subsequent to step (v); and steps (iv) and (vi) are carried out subsequent to step (ii). Also disclosed is an assembly prepared by such process.

Abstract: A corrosivity associated with each of multiple locations near, on, or within a structure exposed to an environment that can corrode the structure is determined. Each of multiple sensor nodes is mounted at a corresponding one of the locations and measures environmental sensor information using one or more environmental sensors and corrosion sensor information using one or more corrosion sensors. The environmental sensor information is processed to obtain for the sensing node a first atmospheric corrosivity category value in accordance with a corrosivity classification system, and the corrosion sensor information is processed to obtain a second atmospheric corrosivity category value for the sensing node in accordance with the corrosivity classification system. One or more of the first and second atmospheric corrosivity category values is provided for use in determining a corrosion classification value for each of the locations.

Abstract: A sensing device includes a pair of contactless electrodes for placement on a coating on a surface of a structure or within or between one or more coatings on or over the surface of the structure. The electrodes function as sensors when activated to generate a current flow through the electrodes at multiple different frequencies. The sensing device also includes contactless control circuitry co-located with or separate from the electrodes that transmits impedance data generated from the activated electrodes. The impedance data is associated with corrosion condition information of the structure and/or the one or more coatings. A data collection system and display system useable with the sensing device are also described.

Abstract: A membrane, suitable for use in a fuel cell, comprises: (a) a central region comprising an ion-conducting polymeric material; (b) a border region which creates a frame around the central region and which consists of one or more non-ion-conducting materials wherein at least one of the one or more non-ion-conducting materials forms a layer; wherein the non-ion-conducting material of the border region overlaps the ion-conducting polymeric material of the central region by 0 to 10 mm in an overlap region.

Abstract: A kit provided for putting in place a regulation size baseball field in a suitably sized park, playground, pasture, sandlot or the like. The components of the kit are contained in a small compact duffle bag and comprise in addition to the bag, 3 regulation size bases, home plate, pitcher's plate, Velcro patches approximately 2 - 4" X 2 - 4", 5 metal stakes, a measuring tape marked along its length at 60 feet 6", 90 feet, and 127 feet 33/8". Preferably there is included in the kit, a brush for cleaning off home plate, an instruction sheet and a ball. The field is the regulation 90 foot square, with home plate, first, second and third base occupying the corners of the squares. Second base is 127 feet 33/8" from home plate, and the pitcher's plate 60 feet 6" from home plate along the same line of measurement. Each of the bases and plates has fixedly attached to the back surface thereof a Velcro patch with the fastening means facing out.

Abstract: A footstool for use by a guitar player. The footstool includes a foot support member, a first leg structure that is attached to the foot support member and delineates a compartment beneath the foot support member. The foot support member and the first leg support member are designed having a composite shape, such that when the footstool is inverted, the footstool conforms to, and facilitates being enclosed within a neck-end of a guitar carrying case. The footstool also includes a second leg structure designed for attachment within the compartment and is intended for use as an elevation adjustment mechanical arrangement for accommodating the guitar player's desired playing position. The compartment's length, depth and width are sized for receiving, and facilitating an unobstructed placement of the neck end (tuning peg end) of a guitar in the guitar carrying case.
