Title: Curb-inlet storm drain systems for filtering trash and hydrocarbons
Inventor: STELPSTRA STEPHEN C
IPC: E03F5/14
Filed: 1999-02-17
Abstract: A modular insert for curb-inlet storm drains creates a composite collection system for trash and for oil or other hydrocarbons and related chemicals. A hopper (110) contains a multitude of irregular, macroscopic fragments (130) of a hydrophobic, compliant, oil-absorbent, copolymer material having high surface area. Preferably, the material is formed with a binder in a novel extrusion process. The fragments are held in place by a removable bottom plate (140), which allows replacement of the filtering fragments (130) , and an internal basket (120).  Trash and debris are collected in the internal basket (120). The hopper (110) is configured to be suspended in a storm drain (100) adjacent to a curb inlet on a bracket and can be installed or serviced through a conventional manhole entry. The hopper (110) has side cutouts (116, 117) that permit lateral overflow from one of the modular units to an adjacent one.

Title: A method and device for despreading an offset signal
Inventor: KLANG GORAN
IPC: H04B1/707
Filed: 1999-03-05
Abstract: A method and a device are disclosed for despreading incoming signals in a receiver for DS-CDMA systems (DS-CDMA = Direct Sequence Code Division Multiple Access) using Offset-QPSK spreading as the transmitting spreading format combined with arbitrary data modulation formats, such as BPSK and QPSK data modulation formats. The receiver has a PN generator (3; 11) for generating a unique PN sequence signal [s(k)] divided into a real and an imaginary component. The input sampled complex valued numbered signal is divided into inphase and quadrature components. The invention is characterized in that the inphase and the quadrature components (yI and yQ) of the input signal are downsampled to provide either two complex samples per chip period or one complex sample per chip period in which later case the downsampling instants are delayed by a quarter of a chip period. Each downsampled complex signals is correlated with the corresponding segments of the complex PN sequence signal of the receiver. The correlation values obtained for odd and even complex samples of the downsampled input signal are summed, in the case when two samples per chip are provided after downsampling.

Abstract: A construction system is used for the erection of a building on a floor slab (12). The system includes a set of structural wall panels (16), bottom connector plates (14) for mounting the panels on the floor slab and side connector plates (18) for connecting adjacent panels. The connector plates seat in slots (40, 46) in the edges of the panels. The bottom connector plates (14) are readily mounted on the floor slab using conventional fasteners, for example nails, screws or bolts. A wall panel may then be set on one or more bottom connector plates and fastened in place using, for example a nail or screw through the wall panel and the connector. Other wall panels are also supported on bottom connector plates and adjacent panels are coupled using side connector plates that fit into the aligned side slots in the panels. The panels are connected to the side connector plates with fasteners extending into the panels and through the connector plates. The panels are pre-drilled to accept the fasteners or otherwise marked to indicate the proper fastener locations. The preferred structural wall panels are constructed as stud wall frames (24) with inner and outer skins (22, 20) of an appropriate sheet material and, where desired, an insulated core. The panels may be equipped with doors or windows, suitably framed. Using this system, the basic structure of the building is set up by erection of the walls. The building may be completed with a set of roof trusses, roofing on the trusses and additional panels that extend from the tops of the structural panels to the roof where required.

Title: Leak-resistant cryptographic indexed key update
Inventor: KOCHER PAUL C
IPC: G06Q20/34
Filed: 1999-07-02
Abstract: Methods and apparatuses for increas-ing the leak-resistance of cryptographic systems using an indexed key update technique are disclosed. In one embodiment, a cryptographic client device maintains a secret key value as part of its state. The client can update its secret value at any time, for example before each transaction, using an update process that makes partial information that might have previously leaked to attackers about the secret no longer usefully describe the new updated secret value. By repeatedly applying the update process, information leaking during cryptographic operations that is collected by attackers rapidly becomes obsolete. Thus, such a system can remain secure (and in some embodiments is provably secure) against attacks involving analysis of measurements of the device's power consumption, electromagnetic characteristics, or other information leaked during transactions.  The present invention can be used in connection with a client and server using such a protocol. To perform a transaction with the client, the server obtains the client's current transaction counter. The server then performs a series of operations to determine the sequence of transformations needed to re-derive the correct session key from the client's initial secret value. These transformations are performed, and the result is used as a transaction session key. The present invention includes a sequence of client-side updating processes that allow for significant improvements in the performance of the corresponding server operations.

IPC: F21V13/04
Filed: 1999-09-27
Abstract: Une source de rayonnement électromagnétique (S0), telle qu'une lampe à arc, est située en un point décalé par rapport à l'axe optique d'une surface réfléchissante toroïdale et concave (M1). Le réflecteur primaire concave (M1) concentre le rayonnement provenant de la source (S0) au niveau d'un point image hors-axe déplacé par rapport à l'axe optique. L'utilisation d'une surface réfléchissante toroïdale permet d'augmenter l'efficacité de collecte dans une petite cible, telle qu'une fibre optique, par rapport à une surface réfléchissante sphérique, par la réduction sensible des aberrations induites par la géométrie hors-axe. Un deuxième réflecteur concave (M2) est placé à l'opposé du premier réflecteur (M1) de manière que le flux total collecté par une petite cible (T) soit encore accru. Dans un mode de réalisation, l'invention concerne des dispositifs dans lesquels le carré de la distance hors-axe divisé par le rayon de courbure est inférieur ou égal à l'étendue de la source de rayonnement électromagnétique (y¿o??2¿/r<s¿o?).
