Abstract: A power over ethernet lighting system includes a plurality of nodes electrically connected to a power/communication bus. Each of the nodes includes a PoE interface, a micro-controller and a PoE driver electrically connected to a PoE luminaire. At least one of the nodes is an emergency management node that includes a rechargeable battery and a PoE battery charger. The system has a maintained mode in which the PoE luminaire of each of the nodes is powered by electricity from the power/communication bus as controlled by the respective micro-controller, which is powered by one of the bus and the rechargeable battery. The system has an emergency mode characterized by a power loss on the power/communication bus, with the PoE luminaire of the emergency management node powered by the rechargeable battery as controlled by the micro-controller, which is also powered by the rechargeable battery.

Abstract: A steering assembly for an in-line roller skate having at least two wheels and at least one horizontally rotatable wheel mechanism for steering. Attached under the sole of a boot, are two planar members that coincide to the general shape and size of the sole. The members are flatwise horizontally, centrally rotatable to each other. A linkage mechanism allows horizontal rotational motion to be transmitted from the sole fixed drive planar member, to a front rotatable wheel mechanism mounted on the underside of the base planar member. Characteristic of ice skates, a level oriented rotational motion of the foot steers the direction of the skate. The horizontal boot-to-wheel rotary motion, provides solid, variable steering for controlled turns, while all wheels are in contact with the riding surface. When the skate is not in contact with the riding surface, a flexible alignment mechanism is then free to restore the steering assembly to the straight line motion of the skate.

Abstract: Method comprises (a) applying to a supporting surface a coating comprised of a photosensitizable water-soluble polymer, a soluble dichromate photosensitizer for the polymer, a soluble vanadate, and particles of the pattern material; (b) exposing the coating to a pattern of actinic radiation until exposed portions of the coating are rendered insoluble; (c) and flushing the exposed coating with an aqueous solvent to remove soluble portions of the coating, while retaining the insoluble portions of the coating in place.

Abstract: The inner surface of a faceplate panel of a cathode-ray tube is cleaned and then precoated with water-insoluble, organic, polymeric particles, the precoating having a weight of 0.08 to 0.80 and preferably 0.20 to 0.40 mg/cm.sup.2. A subsequently applied phosphor-photobinder coating is exposed to a light image and then developed with a turbulent quantity of aqueous liquid. The phosphor-photobinder coating exhibits improved adherence during the developing step due to the presence of the precoating.
