Title: Connector having improved high-voltage surge performance
Inventor: NORTE DAVID A
IPC: H01R13/405
Filed: 2000-08-10
Abstract: The high-voltage surge performance of a Centronic connector (100) is improved through increasing the free-air distance (120', 120") between adjacent pins (102', 102") by tapering the portions of pin bodies (301', 301 ") that extend outwardly from the insulating molding (101 ) of th e connector. The bodies may taper either monotonically (FIG. 5) or concavely (FIG. 7). Additional improvement is obtained by extending the tapered pin-body portions into the molding (FIG. 6) and/or by making the molding with ribs (800) that extend outwardly between adjacent pins (FIG. 8) or by thickening the molding.

Title: Sleeper sofa with an air mattress
Inventor: LARSON TROY W
IPC: A47C17/22
Filed: 1999-03-11
Abstract: A sleeper sofa (10) incorporating an air mattress (40) including a telescoping mattress frame for supporting a mattress support subassembly consisting of hinge panels (31). The hinges (150) used to connect the panels limit the range of motion of adjacent panels (31) to plus or minus 90° from a coplanar arrangement. The panel (34) that defines the seating surface may be supported in the seating position by a pair of side rails (39a, 39b) that lack significant structure in the seating plane. This panel (34) may also include a set of sinuous springs (136) clad in padding. The air mattress (40) used in the sleeper sofa can be a multi-chamber design in which the outer edges (43a, 43b) are inflated to a higher pressure to prevent the user from rolling off the edge. The mattress may also include a longitudinal divider portion (49) inflated to a higher pressure, between individually pressure controlled sleeping portions (45a, 45b) to prevent one user from rolling from a high pressure sleeping area to an adjacent low pressure sleeping area.  The mattress may also include a cover (51) with internally attached elastomeric straps used to assist mattress deflation in specific areas of the mattress such as the foot end.

Title: Network image view server using efficient client-server, tiling and caching architecture
Inventor: CRONIN JOHN C
IPC: G06F17/30
Filed: 1998-02-12
Abstract: A computer network server using HTTP (Web) server software combined with foreground view composer software (50), background view composer software (80), view tile cache (60), view tile cache garbage collector (70) and image files (90) provides image view data to client workstations (20) using graphical web browsers to display the view of an image from the server.  Problems with specialized client workstation image view software are eliminated by using the internet and industry standards based graphical web browsers for the client software. Network and system performance problems that previously existed when accessing large image files from a network file server are eliminated by tiling the image view so that computation and transmission of the view data can be done in an incremental fashion. The vied tiles are cached on the client workstation to further reduce network traffic. View tiles are cached on the server to reduce the amount to view tile computation and to increase responsiveness of the image view server.

Title: Method for increasing thermal convection speed in a thermofusible polymer
Inventor: BAFFELLI GIANNI
IPC: B29B13/02
Filed: 1999-09-01
Abstract: The invention concerns a method for increasing thermal convection speed in a thermofusible polymer, in particular a polyethylene terephthalate, enabling to increase the speed of heat transmission by thermal convection in said polymer, by exposing it simultaneously to at least a thermal radiation source and ultrasonic vibrations. The ultrasonic vibrations are preferably applied intermittently on a surface of the polymer by means of a sonotrode supplied by an ultrasound generator, either directly, or via a liquid in contact with the polymer. Thus the physical characteristics of the polymer can be improved and the heat transmission speed can be varied depending on its form, mass and type.

Title: Deteriorated filament detection
Inventor: PETTERSSON AKE
IPC: H05B47/23
Filed: 1999-10-19
Abstract: A method and an arrangement providing detection of deteriorated lamp filaments (3) in a lamp circuit (11) fed by constant current, in particular for a lamp supervision system for airfield lights. A change in a constant current fed through a lamp circuit (11) is initiated, whereby the lamp filament resistance is determined once in conjunction with the change in current and once a time period later. A difference between the resistance determinations constitutes the deterioration of a lamp filament (3) in comparison with a threshold value.  Hence, no record of previous resistance determinations have to be stored, and lamps (4) can be replaced when the difference matches the threshold value.
