Abstract: Embodiments of the disclosure generally provide polishing pads having a composite pad body and methods for forming the polishing pads. In one embodiment, the composite pad body includes one or more first features formed from a first material or a first composition of materials, and one or more second features formed from a second material or a second composition of materials, wherein the one or more first features and the one or more second features are formed by depositing a plurality of layers comprising the first material or first composition of materials and second material or second composition of materials.

Abstract: Methods are disclosed for killing or knocking down pests selected from the group consisting of cockroaches, ants, bristletails, wasps, hornets, crickets, earwigs, centipedes, scorpions, sowbugs, pillbugs, and spiders. One sprays the pest directly with a solution that is at least 2.8% ester of a polyol (such as sucrose octanoate or sorbitol octanoate). The formulation is designed for use in kitchens, pantries and other areas of the home in which food items may be present. Spray bottle assemblies are also disclosed for delivering the material to the target pest in a desirable manner.

Abstract: A method and device for managing akinetic episodes of "freezing" and "start hesitation" experienced by individuals who suffer from Parkinson's disease and related disorders of the extrapyramidal nervous system projects a beam of light to facilitate mobility. The projection device, used alone or adapted to an assistive support such as a cane or walker, or to an item of clothing, projects a thin beam or discrete pattern of light using a laser, flash or other high-intensity light source to provide a luminous mark in the path of a standing individual. The mark is flashed at will by push-button control, and provides a visual cue to the operator encouraging him or her to step up and over the projected image. This cue breaks the freeze and permits the user to resume motion. Preferably a timer extinguishes the light after a brief interval. Circuitry may blink the light during the projection interval to enhance its efficacy.

Abstract: A stack flow rate measurement system and method utilizes the measured temperatures and pressures of the flue gases in a stack and the measured power supplied to a fan to calculate and display flue gas flow rate without direct measurement of gas velocities in the stack.

Abstract: A fan efficiency monitoring system and method utilizes the measured temperature and pressure differential a fan to calculate and display fan efficiency relative to the temperature differential in an isentropic process at the same inlet temperature and pressure differential. The computed fan efficiency is displayed proximal the fan or at a remote operator's station.

Abstract: A transportable modular assault vehicle water egress and bridge access/egress surfacing or trackway system wherein a plurality of rectangularly shaped planks or sections are joined by flexible hinge members and can be folded accordion fashion and suspended in a container for storing, transporting and rapidly deploying to provide a surfacing upon the shores or banks of bodies of water for the access and egress of military vehicles into and out of bodies of water during military operations.

Abstract: A device for sequentially exhibiting the individual charts in a stack of charts, each of the charts having a plurality of spaced notches along the lower edge thereof, the notches on consecutive charts being misaligned, comprising a display area having a lower shelf on which the stack of charts rest, the shelf being sloped forwardly and downwardly to direct the charts to and off the front edge thereof, a sliding comb assembly positioned adjacent the shelf, the comb assembly including a plurality of spaced teeth, the spacing between the teeth being the same as the spacing between the chart notches, the teeth extending upwardly and inwardly adjacent and along the front edge of the shelf to block movement of the charts off of the shelf except when the notches on a chart are aligned with the teeth, the comb assembly being slideable laterally relative to the shelf to align the teeth thereof with consecutive charts to deliver consecutive charts from the display area, and a spent chart magazine positioned to catch th
