Abstract: Procédé et ensemble de formation de plaques d'impression (2) à partir d'une couche de résine photopolymérisable (R). Ledit ensemble comporte un négatif (38) de masquage arrière placé entre des sources de lumière (42) et une plaque de support (28) sur la face de non impression de la couche de résine. Un substrat de connexion (4) est placé entre le négatif de masquage arrière et la couche de résine. Un négatif (44) de l'image ou des images à former sur la plaque d'impression est placé du côté de la couche de résine qui est destinée à former la surface d'impression (10) de la plaque. Les deux faces de la couche de résine sont exposées au rayonnement ultraviolet et le négatif de masquage arrière sert à permettre le durcissement de la résine uniquement dans les zones de la couche de résine où sont situées les surfaces d'impression. Par conséquent, une pluralité de surfaces d'impression isolées peuvent être formées sur la plaque, lesdites surfaces étant connectées ensemble par le substrat de connexion. De cette manière, il n'est pas nécessaire de produire un fond photopolymérisé sur les plaques d'impression, ce qui permet une récupération accrue de la résine une fois que la plaque est formée.

Abstract: In general the ultrasonic probe for improved fragmentation is comprised of a longitudinal shank (11) having a proximal end (12), a distal end (13), and a shaft (14). The shaft joins the proximal end, and the distal end. The proximal end of the longitudinal shank has a connector (15) for connecting the longitudinal shank to a source of ultrasonic vibrational energy. The distal end of the longitudinal shank may have a blunt or bullet nosed tip (16). The shaft has one or more grooves (17) near the tip which circumscribe the shaft of the longitudinal shank. The walls of the grooves provide surface area on the distal end of the probe in planes generally prependicular ot the axis of the probe. The additional surface area increases the tissue fragmenting surface area of the distal end of the probe without increasing the diameter of the distal end of the probe.

Abstract: An interactive fountain is suitable for installation in a spray or water park partially submerged in a swimming or wading pool. The fountain includes a body having an upper surface sized to support at least one user in a position standing or sitting thereon. The support structure may be formed in situ, or preformed off-site from precast materials. Two or more water nozzles are positioned within the support structure. The water nozzles are connected to a source of water under pressure, as well as to each other by means of a water conduit, whereby in use, water flows from the water source along the conduit and outwardly from each nozzle as a discharged jet, spray or other such stream of water. The water nozzles are configured to permit a user to partially or fully block or obstruct the nozzles, as for example, by the user putting his hand or foot over the nozzle such that when a nozzle is blocked, water is redirected to other non--obstructed water nozzles.

Granted: 2010-04-27
Abstract: The present invention is a radar system for detecting the presence of obstacles. The radar system includes at least one transmitting antenna and at least one receiving antenna. The transmitting antenna receives an input signal and transmits an electromagnetic wave. The electromagnetic wave reflects off an obstacle back to the receiving antenna. The receiving antenna captures the refilected electromagnetic wave and produces an output signal. The output signal is then combined with the input signal in a quadrature mixer. The resulting in-phase (I) and quadrature (Q) signals may be further processed and then transmitted to a processing system. The processing system uses a suitable algorithm, e.g., a back projection algorithm, to estimate the type and location of obstacles that reflected the electromagnetic wave. In an exemplary embodiment, the algorithm is adapted to discriminate between different sizes and locations of obstacles in order to determine if there is a hazard. Based on this information, the processing system then communicates with a visual and/or audible warning system in order to alert the driver about the obstacle if it has been determined to be a hazard.
