Abstract: Mold bottom for the manufacture by blow molding of a container that has a bottom that is equipped with a seat, with this mold bottom including a unit that has a molding face bearing the at least partial impression of the bottom of the container, with a pressure-release air vent being formed in the unit and emptying out, via an inner opening, on the molding face and, via an outer opening, into a pipe for exposure to air, with this mold bottom also including an insert that is provided with at least one projection housed in the air vent and that has a terminal face bearing the impression of at least one part of the seat of the container, with this insert being provided with an inner circuit for heat regulation of the projection and being mounted to move in relation to the unit.

Abstract: A plastic container (1) is provided with a body (5) and a bottom (6) that extends from a lower end of the body (5), the bottom (6) including: a peripheral base (7) defining a bearing surface (8); a concave arch (10) that extends from a central zone (11) to the base (7); and a series of main reinforcing grooves (13) hollowed into the arch, extending radially from the central zone (11) at least to the base (7) and dividing the arch into a series of angular sectors (15). Where each groove (13) joins each sector (15) of the arch (10) adjacent thereto it is bordered laterally by a reinforcing rib (18) projecting in relation to the sector (15).

Abstract: Implementations described and claimed herein provide systems and methods for flood hazard zone modeling. In one implementation, one or more relevant stream segments are identified from an input stream network. One or more cross profiles are defined for one or more selected points on the relevant stream segments, with the selected points located within a flood hazard area. A high resolution flood level elevation map is generated by interpolating flood level elevation from the selected points. A flood depth map is generated having a flood depth value for each of the selected points computed as a difference between the high resolution flood level elevation map and a terrain elevation. One or more flood zones are defined in the flood depth map. The flood zones have a positive flood depth for a return period.

Abstract: Container (1) made of a plastic material, provided with a base (7) including a standing ring (8) forming a support flange (9) and a diaphragm (11) extending from the standing ring (8) to a central portion (10), the diaphragm (11) being capable of standing in an outwardly-inclined position. The diaphragm (11) connects to the standing ring (8) at an outer junction (12) forming an outer articulation of the diaphragm (11). The diaphragm (11) connects to the central portion (10) at an inner junction (13) forming an inner articulation of the diaphragm (11). The diaphragm (11) is invertible with respect to the standing ring (8) from the outwardly-inclined position to an inwardly-inclined position. In the inwardly-inclined position, at least an inner portion (16) of the diaphragm (11) adjacent to the inner junction (13) is curved in radial section, with a concavity turned outwards.

Abstract: A tire pressure monitoring device and system includes a support or housing mounted to a rim of a wheel of a vehicle. A casing is movably secured to the support and a pair of spaced magnets are disposed within the casing. The casing is collapsible for varying the length of the casing in response to changes in the tire pressure to move the magnets relative to each other. A sensor is mounted a distance from the casing for sensing a presence of each of the magnets. A controller is in communication with the sensor to determine the length of the casing and the relative movement between the magnets to calculate any changes in tire pressure.

Abstract: A flexible built-in self-test (BIST) circuit is incorporated into an integrated circuit (IC) for testing one or random access memories or other memories embedded in an integrated circuit regardless of the number, size or test requirements of the memories. Input data from a controller that may be conveniently partitioned among components internal and external to the IC, supplies data to the BIST circuit indicating the size of the embedded memories to be tested and selecting from among several modes of BIST operation.

Abstract: A field programmable gate array (FPGA) and a decryption circuit are implemented within a common integrated circuit (IC) or within separate ICs enclosed within a common IC package. The decryption circuit decrypts an input FPGA program encrypted in accordance with a particular encryption key and then writes the decrypted FPGA program into the FPGA. Thus an FPGA program encrypted in accordance with a particular encryption key can be used to program only those FPGAs coupled with a decryption circuit capable of decoding the encrypted FPGA program in accordance with that particular encryption key. Since the decryption circuit and the FPGA are implemented in the same IC, or within the same IC package, the decrypted FPGA program the decryption circuit produces cannot be readily intercepted and copied.

Abstract: A built-in replacement analysis (BIRA) circuit allocates spare rows and columns of cells for replacing rows and columns of an array of memory cells in response to an input sequence of cell addresses, each identifying a row address and a column address of each defective cell of the cell array. The BIRA subsystem, including a row register corresponding each spare row and a column register corresponding to each spare column, responds to incoming cell addresses by writing their included row address into the row registers, by writing their column addresses into the column registers, and by writing link bits into the column registers. Each link bit links a row and a column register by storing row and column addresses of a defective cell. The BIRA subsystem also writes a “multiple cell” bit into each row register to indicate when the row address it stores includes more than one defective cell.

Abstract: A control arrangement for a fuel system having a fuel pump (13) for supplying fuel through a variable orifice flow metering valve (15) to an engine main fuel control (45), the control (45) controlling the fuel pressure differential across the orifice of the metering valve (15). A head sensor includes a movable diaphragm (51), a bypass valve (47) for diverting fuel from the fuel pump away from the metering valve (15), and a coupling between the diaphragm (51) and the bypass valve (47) whereby the bypass valve (47) opens and closes in response to diaphragm (51) motion. The metering valve orifice fuel pressure differential is applied across the diaphragm (51) so that a valve spool (55) may open and close to maintain the pressure differential across the metering valve (15) substantially constant. A bias spring (54) normally biases the spool (55) closed.
