Title: System for Coupling External Leads to a Multitap Transformer
Inventor: HAYS ERIC L
IPC: H01R11/26
Filed: 1996-11-26
Abstract: A coil assembly for use in an inductive apparatus, is comprised of a conductive material, either copper or aluminum, continuously wound around a circular or rectangular shape. At a predetermined number of turns, a terminal or tap is formed in the conductor. The tap is essentially a bump in the conductor that will protrude from the coil and be accessible to make connections to it after the coil assembly is complete. The insulation of the conductor is removed from the outside edge of the bump to form a point of contact. A C-clamp, formed from spring steel or other conductive material, functions to secure an external conductor having a lug attached to an end of conductor to the formed terminal. A bolt through the lug is secured by a tapered depression in the C-clamp that functions as a nut. The C-clamp includes an extension that provides additional pressure between the point of contact and the lug to make an electrical contact with a portion of the formed tap and the lug. To provide an anti-rotation feature, the C-clamp also has corner ends that are formed downward over the lug.

IPC: B60R21/16
Filed: 1995-09-13
Abstract: In a system (10) and method for controlling actuation of a vehicle passenger safety device in response to events possibly requiring actuation of the safety device, a differential measure (m1(t)) is generated (18) based on stored consecutive values for vehicle acceleration while a measure (m2(t)) correlated with the progress of the events are generated (26 and 30) by providing as input to a first accumulator (24) either a weighted transitory value for received acceleration, or a weighted alternative value that is equal to twice a first predetermined threshold value (x1) minus the transitory value. The differential measure (m1(t)) is thereafter combined (32) with the progress measure (m2(t)) to effectively "damp" or weight the former as a function of an event progress, whereupon the resulting combination is accumulated in a second accumulator (34) to obtain a measure (m3(t)) predictive of event severity, with the safety device being actuated when the predictive measure (m3(t)) exceeds a second predetermined threshold (x2).

Title: High-Speed Polarization Scrambler with Adjustable Chirp
Inventor: HEISMANN FRED LUDWIG
IPC: G02F1/035
Filed: 1997-03-18
Abstract: Two separate electrooptic phase modulators are used in a modified Mach-Zehnder interferometer to vary the absolute and relative optical phases of two orthogonally polarized modes of an input signal independently of each other. A conventional Y-branch splitter on lithium niobate splits the input signal equally into the two waveguide phase modulators and an external polarization splitter recombines the two phase modulated signals in orthogonal polarization states.  The polarization in the interferometer is maintained by connecting the outputs of the two phase modulators to polarization maintaining fibers.  An alternate embodiment of the present invention uses an additional 3-dB directional coupler to mix the two phase modulated signals before they are combined in orthogonal polarization states.

Filed: 1997-05-22
Abstract: The invention discloses a humidifying device which consists in a thermally conductive casing which is adapted and correctly dimensioned to fit over a conventional electrical radiator without preventing it from heating the ambiant air simultaneously. The casing is destined to be at least partially filled with water, and upon the radiator generating heat, the water temperature will gradually increase and water will evaporate into the ambiant air through outlets in the top of the casing due to the heat being conducted through the radiator and casing to the water. The water vapor outflow rate can be selectively adjusted by means of a pivotable heat deflector or alternately by adjusting the distance between the radiator and the casing. A sponge member filled with bactericide is inserted into the casing and is submerged in water.

Patent CA-2210195-A1 (CA)
Inventor: CHENNAKESHU SANDEEP
IPC: H04B17/00
Filed: 1996-01-19
Abstract: Characteristics of the radio channel are used to establish key sequences for use in encrypting communicated information.  These characteristics are the short-term reciprocity and rapid spatial decorrelation of phase of the radio channel.  The keys can be established with computations equivalent to a bounded distance decoding procedure, and the decoder used to establish a key may be used for processing the subsequent data transmission.  Compared to classical and public-key systems, an alternative mechanism for establishing and sharing key sequences that depends on a physical process is provided in which each party need not generate a pseudorandom quantity because the necessary randomness is provided by the temporal and spatial non-stationarity of the communication channel itself.  By using a channel decoder, the probability of two users establishing the same secret key is substantially unity, and the probability of an eavesdropper establishing the same key is substantially zero. Also, the number of possible keys is large enough that finding the correct one by exhaustive search is impractical.

Abstract: L'emballage et même le suremballage des produits de consommation est une pratique courante dans les pays industrialisés. Comme ces emballages sont formé s essentiellement de polymères non-biodégradables, ils causent actuellement des problèmes environnementaux. Ces problèmes environnementaux sont retrouvés non seulement dans les pays industrialisés mais aussi dans les pays en voie de développement. Cette situation a favorisé le développement de différent films, plus écologiques, à partir d'éléments biodégradables à base de polysaccharides, de protéine et/ou de lipides. Nous avons mis au point un film protéique biodégrada ble formé a partir d'un sel de la caséine. D'origine laitière, la caséine est abond ante et pourrait même être récupérée des laits invendus. Le processus de polymérisation est induit par irradiation gamma. En effet, l'interaction de radicaux hydroxyl avec les tyrosines présentes dans la protéine crée une liaison covalente (bityrosine). L 'ajout d'agent plastifiant est indispensable afin de produire un film plus souple et mo ins friable. La présence de glycérol n'inhibe pas la formation de bityrosine. Elle protège la protéine de la dénaturation causée par l'irradiation, augmente le pouvoir déform ant et diminue la résistance à la rupture du film. Les essais de biodégradabilité, con duits dans nos laboratoires, ont démontré que le film produit par irradiation gamma es t accessible aux attaques enzymatiques de Pseudomonas fragi.

Title: Receiver with analog and digital channel selectivity
Inventor: SUOMINEN EDWIN A
IPC: H03H17/02
Filed: 1998-01-26
Abstract: A radio receiver for receiving radio frequency (RF) signals includes an analog down-converting and filtering section for down-converting and selecting the RF signals to an intermediate passband and a stopband which substantially determine the widest bandwidth of operation of the radio receiver. An analog-to-digital converter converts the intermediate frequency signal to a sampled digital signal. A digital filtering section, responsive to the sampled digital signal, includes wideband and narrowband digital filters for providing wide bandwidth and narrow bandwidth baseband quadrature output signals for the widest bandwidth of operation and a narrow bandwidth of operation at a frequency within a passband. The wideband digital filtering is designed to only provide a modest amount of additional stopband attenuation with a significantly sharper transition band rolloff from passband to stopband. When this limited digital filtering is applied to the signal that has already been subjected to the analog filtering, the selectivity of the overall receiver frequency response is improved. The receiver may be used for multi-bandwidth operation by simply adding digital filtering to define any narrower passband of interest. This allows bandwidth switching to take place without any changes to the analog circuitry. Simultaneous processing of both wide and narrow modes of operation may be done in the digital signal processor (DSP) performing the digital filtering.
