Title: Method and apparatus for forming a can end having an anti-peaking bead
Inventor: FIELDS BRIAN
IPC: B21D51/38
Filed: 1999-08-13
Abstract: An apparatus and method for forming a narrow, tightly radiused annular anti-peaking bead in a can end in a multi-station conversion press. In a first forming station, a metal blank is first drawn into a cup shaped blank having a side panel and then reformed by reversing the action of the drawing tooling so as to fold the side panel into an initial, relatively broad annular bead. The initially beaded can end is then transferred to a second forming station where its periphery is pre-curled and the annular bead is reworked so as to reduce its width and radii of curvature. The reworking of the bead is performed by free drawing a tool over the inner wall of the bead without drawing or bending the interior surface of the bead around a tool so as to avoid cracking or excessive thinning of the metal. The seaming panel of the can end is firmly clamped during the reworking to maintain control over the location of the bead. The can end having the reworked bead is then transferred to a third forming station for final curling of the seaming panel.

Title: System and method for gradual transition of local phone services from pstn to next generation network
Inventor: SMYK DAREK A
IPC: H04M3/00
Filed: 1999-12-08
Abstract: For any telephone service subscriber, local services could be offered based on either the packet switched next generation network NGN (402) or the PSTN  network (400). The network can be configured such that for each particular phone line, the line's services are based either on a PSTN's class 5 switch (418) or on an NGN's service manager SM (416). The local service provider, through software reconfiguration could quickly and efficiently move service subscribers' phone lines from class 5 switch (418) based local services to SM  (416) based services, and vice-versa. If a call origination is attempted from a phone connected to an access gateway, the SM (416) will instruct the network to handle the call differently depending on whether the services should be offered based on the class 5 switch (418) or the SM (416). If the services ought to be offered through the class 5 switch (418), then the SM (416) will establish a virtual local loop connection between the phone and the class 5 switch (418). Subsequently, the class 5 switch (418) will provide the dial tone, collect the dialed digits and proceed with establishing the call. The NGN simulates a traditional local loop. If the local services are offered for the customer through the SM (416), the SM (416) will fully control the call establishment and route the call bypassing the class 5 switch (418).

Title: Photosensor system and drive control method thereof
Inventor: NAKAMURA YOSHIAKI
IPC: H04N5/367
Filed: 2000-10-19
Abstract: A photosensor system having a photosensor array constituted by two-dimensionally arraying a plurality of photosensors includes a driver circuit for supplying a drive signal to the photosensors, and a controller for controlling reading operation of a subject image and sensitivity setting. Before the start of normal reading operation of a subject image, pre-reading operation of changing the image reading sensitivity at a plurality of stages for respective rows is executed. A row in an optimal image reading state is easily determined based on the dynamic range distribution of the lightness data of read image data or a dynamic range distribution from which an abnormal value deviating from the main change trend of lightness data is removed, and the linearly differentiated value of the dynamic range. An image reading sensitivity set for this row is set as an optimal sensitivity. This can simplify sensitivity setting processing and shorten the required time.

Abstract: The present invention relates to a flooring structure in which the beams (1,  8) of the flooring structure are not interconnected with one another apart from in certain discrete points, for example in bearing supports. In this instance, the bearing beams (1, 8) of the flooring structure do not dynamically co-operate with one another in any significant manner. As a result, improved footstep sound insulation will be obtained since the floori ng structure only reacts locally to a dynamic loading. The flooring structure emits only sound in an area close to the applied dynamic loading. In the flooring structure according to the present invention, the beams (1, 8) lie considerably closer to one another compared with that which has previously been normal for light wooden flooring structures. In one embodiment of the present invention, the beams (8) and/or studs (10) placed between the beams (1, 8) and floor panels (5) are provided with grooves (9). As a result of these grooves (9) torsional and compression rigidity at the anchorage points  with the floor are reduced, which gives improved footstep sound insulation compared with beams and/or studs without grooves.

Title: Flexible stent
Inventor: MAJERCAK DAVID C
IPC: A61F2/90
Filed: 2002-03-01
Abstract: A preferred embodiment of a stent provides a folded strut section that provides both structural rigidity and reduction in foreshortening of the stent mechanism. A flexible section provides flexibility for delivery of the stent mechanism. In a second embodiment, flexible section columns are angled with respect to each other, and to the longitudinal axis of the stent. These relatively flexible sections are oppositely phased in order to negate any torsion along their length. In yet another embodiment, the flexible connector can take on an undulating shape (like an "N"), but such that the longitudinal axis of the connector is not parallel with the longitudinal axis of the stent. Finally, a new method is disclosed for making stents. The method consists of performing a standard photochemical machining process of cutting, cleaning and coating the tube with a photoresist. However, unlike former methods, the photoresist image is developed on the surface of the cylindrical metallic tube, which results in a controlled variable etching rate at selected sites on the cylindrical metallic tube during the etching process. Further embodiments provide living hinge connectors and connections along the length of the radial strut member.
