Title: Procede dynamique non invasif destine a mesurer une distance ou sa variation au moyen d'elements dielectriques
Inventor: BISSONNETTE MARC
IPC: G01B7/02
Filed: 2002-03-25
Abstract: L'invention concerne un procédé non invasif et un système permettant d'effectuer une mesure dynamique d'une distance ou de ses variations au fil du temps, cette distance constituant l'épaisseur, ou ses variations, d'un matériau diélectrique compressible situé entre une ou plusieurs autres couches diélectriques solides étroitement espacées d'épaisseur constante et une surface conductrice ou semi-conductrice. Le procédé consiste à place un capteur capacitif sur la couche extérieure du matériau diélectrique, ledit capteur étant constitué de deux plaques parallèles électriquement isolées l'une de l'autre, à soumettre la première plaque à un signal haute fréquence, à mesurer les valeurs de tension et de courant produites au fil du temps par le signal haute fréquence entre la plaque du capteur la plus proche de la surface de la couche extérieure du matériau diélectrique et la surface conductrice ou semi-conductrice, puis à en déduire la distance susmentionnée ou ses variations.

Title: Digital differential phase-shift keyed decoder
Inventor: PEISCHL MARK L
IPC: H04L27/233
Filed: 1989-10-24
Abstract: DIGITAL DIFFERENTIAL PHASE-SHIFT KEYED DECODER                      Abstract Digital circuits increase reliability of a decoder for differential phase-shift keyed signals.  A tapped delay line delays the input signal by a variable amount, substantially equal to one bit time of the modulated data, and provides the delayed signal to a multiplier for generating a product signal.  In response to changes in frequency of the  input signal,  a control system selects different taps of the delay line to provide the delayed signal for multiplication by the modulated input signal.  The control signal includes a feedback loop, wherein a phase difference between the signal at the selected tap and the input signal is used to change a count  in  an  up/down  counter.    A  tap  selecting multiplexer provides an output from specified taps in response to particular values of the count.

Abstract: ABSTRACT       The invention is an aid in breeding valuable horses where by a piece of plywood is used on a post with board fences to other posts so the breeder does not get hurt or injured nor can the stallion get hurt or injured; by the kicking out of the mare, if she is not in the proper heat cycle.  The operator stands to the left of the mare behind a swinging peice of plywood teasing the mare with the stallion and preparing the stallion to mount the mare if she is ready to be bred.      The mare has been so positioned by a rope on a ring over her neck and through the halter to a post.  She has a post and fence to her right and left side so she can-not get away from the stallion.  The colt, if she has one, is left at the mares right side near rear of the dam. This helps to calm the mare.     This invention can help the breeder in these ways.  (1)  This is a new invention so the breeder nor the valuable horse cannot get kicked and injured.  (2)  It can primarily be used by horse breeders mostly for STANDARDBRED OR LIGHT HORSES.  (3)  It is an excellent method to be used if the mare tends to be difficult.  (4)  Used for natural breeding of valuable horses.

Abstract: 1.         Cigarette pack, especially hinge-lid box.   2.1.       Known conventional cigarette packs, especially those with a hinge-lid box (10), an inner blank (29) made of tin-foil and possibly an outer wrapping made of plastics foil are not suitable for disposing of smoked cigarettes (waste-cigarettes 48). It is felt to be undesirable that smoked cigarettes are thrown away individually. This goes especially for "artificial cigarettes" which have recently appeared on the market.   2.2.       In order to achieve an improved waste-disposal, the present cigarette pack, especially as regards its em-bodiment with hinge-lid box (10), is provided with a waste compartment (47) for holding waste-cigarettes (48). Part of the inner blank (28), namely its rear-wall (30), forms a partition between the waste compartment (47) and a cigarette compartment (46). Smoked cigarettes are reinserted into the pack through an insert-opening (54).     2.3.       The cigarette pack practically does not differ from conventional cigarette packs regarding its dimensions and shape. But it still offers the possibility of dis-posing of the cigarette pack including all smoked cig-arettes as a whole.

Abstract: METHOD OF ADAPTIVE CONTROL FOR CLOSED THROTTLE    DOWNSHIFT IN AN AUTOMATIC TRANSMISSION            ABSTRACT OF THE DISCLOSURE         In an automatic transmission, clutch-to-clutch closed throttle downshifting is controlled by filling the on-coming clutch at a maximum pressure command for a set period while commanding the off-going clutch pressure to a low value and exhausting the off-going clutch before the end of the fill period.  At the end of the fill period the on-coming pressure is set to an initial value and then ramped up until turbine speed is pulled up due to off-going clutch slippage.  Then a closed-loop profile control period starts wherein the slip of the on-coming clutch is measured and controlled to a slip profile.  When synchronization of the on-coming clutch is detected, maximum pressure is commanded.  Parameters for controlling the quality of a shift such as on-coming clutch initial pressure and on-coming clutch fill time are automatically adjustable during vehicle use to correct shift aberrations which degrade shift quality.
