Abstract: A device and methods for displaying representations of objects, solids, and surfaces volumetrically in a medium containing one or more photochromic compounds comprising at least one UVA light source arranged to project a beam of UVA radiation and irradiate at least one portion of a display volume incorporating at least one display medium which includes at least one photochromic compound. The irradiance of the irradiated portion of the display medium being sufficient for clear-to-colored transitions of voxels of the display medium from a transparent state to a colored state. After a time period after the irradiation, the irradiated voxels activated in the colored state transition by a colored-to-clear transition into the transparent state.

Abstract: A microcatheter includes an inner polymeric tube defining an inner lumen. It includes a proximal section with an inner wire layer helically wound in a constricted state over the inner polymeric tube and includes an outer wire layer helically wound over the inner wire layer in a constricted state within the proximal section. It includes a distal section with a distal wire layer helically wound in a constricted state and having an outer diameter. The proximal and distal sections are joined. The outer diameter of the outer wire layer is substantially the same as the outer diameter of distal wire layer at the location where the proximal and distal sections are joined.

Abstract: A shingle including a flexible sheet; a photovoltaic panel attached to the flexible sheet; an electrical conductive path extending from a first side of the shingle to an opposite side of the shingle; a connector on one end of the electrical conductive path, and a mating connector on an opposite end of the electrical conductive path.

Abstract: In various embodiments of the present invention, tiered command-propagation methods are employed within client computers to ensure that monitoring-and-management-related commands are reliably propagated from server computers to client computers. When possible, command propagation is initiated by server computers through a notification process. When the notification process is inoperable, client computers poll one or more monitoring-and-management server computer for commands. When a failed or interrupted notification process is subsequently restored to operability, client computers automatically discontinue command polling and resume relying on server notification for command propagation.

Abstract: An interworking function (IWF) is coupled to a switch of a packet network and communicates with the network switch based on an Ethernet clock signal or some other type of clock signal. A primary reference clock (PRC) of the network generates a PRC signal, and a timing analyzer determines timing information indicative of timing relationships between the Ethernet clock signal and the PRC signal. The timing analyzer periodically transmits such timing information, and the IWF uses the timing information to generate a PRC signal that is traceable to the network PRC signal.

Abstract: The present invention relates to apparatus and methods for winding filament to create a structure. In one embodiment, the invention includes the application of filament to a rotating mandrel to create a desired shape. The invention includes the filament winding of both simple and complex shapes.

Abstract: An apparatus used with a range pole and survey instruments for leveling and setting elevations and a method of use of the apparatus. A frame holds a range pole, on an embed plate, without assistance of a surveyor's assistant while a surveyor communicates with an iron worker to effect elevation adjustments of the embed plate.
