An LED pump light with multiple phosphors is described. LEDs emitting radiation at violet and / or ultraviolet wavelengths are used to pump phosphor materials that emit other colors. The LEDs operating in different wavelength ranges are arranged to reduce light re-absorption and improve light output efficiency.

LED packages, and LED lamps and bulbs, are disclosed that are arranged to minimize the CRI and efficiency losses resulting from the overlap of conversion material emission and excitation spectrum. In different devices having conversion materials with this overlap, the present invention arranges the conversion materials to reduce the likelihood that re-emitted light from a first conversion materials will encounter the second conversion material to minimize the risk of re-absorption. In some embodiments this risk is minimized by different arrangements where there is separation between the two phosphors. In some embodiments this separation results less than 50% of re-emitted light from the one phosphor passing into the phosphor where it risks re-absorption.

The invention relates to sweat activity measurement, e.g. for determining a physiological state of a subject, embodied by a method as well as a kit with an immittance measuring circuit and electrodes with contact electrolyte. Sweat activity is considered a transport phenomenon and can be defined as a flux, e.g. gram water per skin area per second. Prior art methods determining water absorbed per gram dry stratum corneum measures skin moisture and do not truly reflect sweat activity.

An anti-rewet press fabric for paper and board machines includes a barrier layer such that during compression in the press nip, the water is forced through the barrier layer, but is prevented from flowing back to the paper web during expansion. The barrier layer comprises a continuous material possessing, for example square, rectangular, tetrahedral, circular or oblong conical inclusions with a smaller opening on the bottom than on the top of the structure. Each of these “funnels” effectively constitutes a one-way valve and creates a vacuum to prevent re-absorption of water by the paper sheet. Under pressure, the structure of the barrier layer allows water to flow into the cones and out of the smaller opening in the bottom. Upon expansion, the smaller opening in the bottom of the structure restricts backward water flow and creates a vacuum on the other side. The vacuum increases water retention in the press fabric and prevents rewetting of the paper sheet. Another embodiment of the invention is described herein, wherein the barrier layer exists as a separate fabric fed through a press section. In this embodiment, the “separate fabric” can just be the “conical inclusion sheet” itself. That is, the sheet itself constitutes an inventive belt having anti-rewet properties.
