Patent CA-2133858-A1 (CA)
Title: Reversing drive
Inventor: MCGUIRE BERNARD
IPC: F16H31/00
Filed: 1994-10-07
Abstract: A shaft is provided with a low speed oscillating progressive drive by means of hydraulic cylinders which operate a lever mechanism which may be clutched to and declutched from, the shaft. A pneumatic control system senses the position of the pistons of the hydraulic cylinders and provides a controlled oscillation of the cylinders. When the pistons cause the shaft to rotate in one direction a sensor causes the lever mechanism to be declutched from the shaft after a selectable number of degrees of rotation. The pistons continue their stroke to the normal limit where the lever mechanism is caused to be once more clutched to the shaft. This operation is continued producing an oscillatory progressive rotation of the shaft.

Abstract: A buoyancy compensator assembly for a diver is provided with a vest having an inner gas impermeable layer adapted to face  a  wearer  and  a  congruently  shaped  opposing  gas impermeable outer layer.  The peripheral edges of the inner and outer layers are sealingly bonded to each other.  The vest has an opening through   a back portion of the vest.   A backpack for removably retaining a longitudinally extending breathing gas tank has a baseplate generally disposed within the opening.  Attached to the periphery of the baseplate is an edge. The edge is disposed between and integrally bonded to the inner and outer layers whereby the layers form a chamber to be selectively inflated to adjust the buoyancy of the diver.  A restraining sheet is located between and alternately attached to the inner layer and outer layer to form aligned bands.  The sheet forces the inner layer to curve inward about the sides of the diver when the chamber is inflated.  The backpack is constructed so that when the breathing gas tank is strapped onto the backpack the baseplate curves to fit about the back of the diver.

IPC: G07B15/00
Filed: 1995-06-02
Abstract: A card system and method for accessing a public transit system that employs a card pre-encoded with trip data permitting a set number of trips on the transit system and a card processing unit to receive and process a card each time access to the transit system is desired. The card processing unit includes  a time write head to record the time of current use on the card and a time read head to retrieve the time of last use from the card. A microprocessor computes the difference between the time of current use and the time of last use.  A trip read head scans the encoded trip data to determine the number of trips remaining on the card and a trip write head is provided to write to the card to decrement the number of trips by a given amount after use.  The trip write head and the time write head are employed only if the difference between the time of current use and the time of last use is greater than a preset period.  The card system automatically handles access to the transit system and transfers from one transit vehicle to another within the transit system thereby permitting faster vehicle loading, reduced fare evasion and increased driver concentration on vehicle operation.

Abstract: A photographic printing apparatus for printing an image projected from a film on to a photosensitive material is disclosed. The apparatus has a lens system for forming the image of the film located at an exposing position on the photosensitive material, a lens-system drive mechanism for supporting and moving the lens system along an optical axis thereof, a temperature sensor for detecting an ambient temperature around the lens-system drive mechanism, and a control device connected with the temperature sensor and the lens-system drive mechanism. The control device has a memory for storing position correction information for the lens system at each possible temperature and a driver for outputting a correction operation signal obtained based on the correction information to the lens-system drive mechanism. Depending on an operation condition of the photographic printing apparatus, a timing of outputting the correction operation signal from the driver to the lens-system drive mechanism is determined.

Title: System and method for noninvasive hematocrit monitoring
Inventor: STEUER ROBERT R
IPC: A61B5/1455
Filed: 1993-04-12
Abstract: A system for determining the hematocrit transcutaneously and noninvasively. Disclosed are a finger clip assembly (6) and an earlobe clip assembly (10), each including at least a pair of emitters (1, 2) and a photodiode (3) in appropriate alignment to enable operation in either a transmittion mode or a reflectance mode. At least two, and preferably three, predetermined wavelengths of light are passed onto or through body tissues such as the finger (7), earlobe (11), or scalp, etc. and the extinction of each wavelength is detected.      Mathematical manipulation of the detected values compensates for the effects of body tissue and fluid and determines the hematocrit value. If a fourth wavelength of light is used which is extinguished substantially differently by oxyhemoglobin and reduced hemoglobin and which is not substantially extinguished by plasma, then the blood oxygen saturation value, is determinable independently of the hematocrit value. It is also within the scope of the present invention to detect and analyze multiple wavelengths using a logarithmic DC  analysis technique. In this embodiment, a pulse wave is not required. Hence, this embodiment may be utilized in states of low blood pressure or low blood flow.

Abstract: Dans le milieu de l'éducation plusieurs moyens sont mis en oeuvre afin d'attirer l'attention des jeunes. Ainsi plusieurs types de manuels, livres et techniques ont été essayé afin de réussir à obtenir et garder cette attention des étudiants tant recherchée. Le type de livre dont il est question ici consiste en une série de pages reliées en une marge. Les dessins sont sensiblement les mêmes d'une page à l'autre. Les sujets traités dans ces livres peuvent être très variés ils ont cependant une chose en commun. Ils contiennent au moins un élément statique, par exemple un arbre, et au moins un élément en mouvement, par exemple le soleil. L'objet statique se retrouve à la même place d'une image à l'autre, alors que l'objet en mouvement se déplace dans l'espace offert par la page. Les images lorsque regardées en séquences créé le mouvement du soleil l'opposant à la statique de l'arbre. Ce procédé de passation d'images en séquence dans le but de démontrer le mouvement en est un qui date de très longtemps. Cependant lors de recherches préliminaires selon une liste fournie par le bureau des brevets qui a été complété de recherche supplémentaire, le document breveté se rapprochant le plus près de ce type de matériel est le suivant. Brevet no. 725,054, émis le quatre janvier 1966 à monsieur Richard Finkel à Newton au Massachusetts, États-Unis. Ce type de matériel est toutefois très différend de celui que je vous présente ici. Ainsi, l'animation visuelle du livre de Mr.Finkel est basé sur une série de lamelles touché du doigt qui peut être supporter d'un texte.
