Patent CA-2140142-A1 (CA)
Title: Document Counting Batching Apparatus with Counterfeit Detection
Inventor: CARGILL N ALLEN
IPC: G07D7/04
Filed: 1993-07-02
Abstract: An apparatus for counting and verifying documents (10) includes an improved stripper assembly (36a) and a digital control network (6A). The stripper assembly includes a friction belt (38) which is rotated counter to the direction that documents are fed into the apparatus. The tension of the friction belt may be adjusted by rotating of an eccentric member (117). The digital control network coordinates the operations of counting and verifying documents. A transport mechanism (2D) moves documents along a guide path (50) through the apparatus. Sensors (80, 82, 84, 86) are located along the guide path for determining optical and magnetic characteristics of the documents and producing signals relative thereto. The measured signals are sampled and digitized by an analog-to-digital converter (304) under the control of a microprocessor (302). Multiple samples of the sensor signals are accumulated within memory as each document passes adjacent to the sensors. The accumulated values are compared with reference values in order to verify each document after it has passed adjacent to the sensors. Documents are counted after verification. Individual piece counts and monetary values of such piece counts are provided.

Title: Ultrasonic measurement system for the determination of bone density and structure
Inventor: MELE RUGGERO
IPC: A61B8/08
Filed: 1995-01-13
Abstract: Electronic system     for measuring the density and structure of bone, in which an electronic central unit       is  equipped  with  ultrasonic  calipers designed to be applied to a segment of the human body (for example, a finger)  containing bone tissue to be examined.  The central unit     is designed to display on a screen       an image      of the ultrasonic signal transmitted through the bone tissue and highlight, on that image     ,  two vertical marker lines correlated with the velocity with which the ultrasound signals are transmitted through the bone tissue and the velocity  of  transmission  of  the  ultrasound  signals through soft tissue.  These vertical marker lines mark off the portion of the image that represents the ultrasonic signal received after passing through the bone tissue.  The amplitude of this signal depends on the absorption of the ultrasound when passing through the bone tissue.
Patent CA-2141684-A1 (CA)
Title: Concentrating and collecting optical system using concave toroidal reflectors
Inventor: BAKER GLENN
IPC: F21V14/00
Filed: 1993-07-29
Abstract: An electromagnetic radiation source (S) such as an arc lamp, is located at a point displaced from the optical axis (o) of a concave toroidal reflecting surface. The concave primary reflector (M1) focuses the radiation from the source at an off-axis image point that is displaced from the optical axis. The use of a toroidal reflecting surface enhances the collection efficiency into a small target (T), such as an optical fiber, relative to a spherical reflecting surface by substantially reducing aberrations caused by the off-axis geometry. A second concave reflector (M2) is placed opposite to the first reflector to enhance the total flux collected by a small target.

Abstract: Une famille de protéases endogènes des cellules de Streptomyces dégrade les protéines exogènes sécrétées par les cellules hôtes de Streptomyces. Les protéines précedemment non identifiées comprennent (1) une aminopeptidase tripeptidyle nommée "Tap", (2) une aminopeptidase tripeptidyle nommée "Ssp", (3) une X-Pro-Metalloendoprotéinase nommée "XP-Mep", et (4) d'autres protéases dérivées de Streptomyces qui dégradent certains substrats dans certaines conditions. On atténue la dégradation par inhibition sélective des protéases sécrétées ou au moyen de souches améliorées exemptes de protéases de dégradation ou présentant des protéases de dégradation défectueuses. On a mis au point un inhibiteur irréversible fondé sur le mécanisme et la spécificité de substrat de la protéase cible. On a également produit des hôtes exprimant des protéases. Lesdites protéases peuvent être utilisées dans des dosages immunologiques et pour l'extraction protéolytique de peptides et de polypeptides en vue d'améliorer la sécrétion de protéines exogènes.

Inventor: WURST WILLIAM C
IPC: H01S5/0683
Filed: 1996-07-22
Abstract: A low-cost monitor includes two comparators which are adapted to form a window comparator which frames a laser transmitter's normal range of operation. An apparatus for generating an amplified back-face-monitor voltage corresponding to the laser transmitter's optical output power level is coupled to the window comparator. A reference voltage is also coupled to the window comparator which defines the upper threshold of the normal operational range. A controllable variable voltage source is coupled to the window comparator and is used to define the lower threshold of the normal operating range, where this lower threshold has two associated threshold values as described above. The lower threshold is initialized to the first threshold value which corresponds to an end-of-life operating state of the laser transmitter. When the back-face-monitor voltage signal equals or drops below the first threshold value, an alarm signal is generated by the laser monitor, and the controllable variable voltage source is switched to a second state for providing a second threshold value which corresponds to failed operating state of the laser transmitter. As the optical output power level continues to decline with temperature and time, it eventually falls belows the second threshold and a second alarm is generated to indicate failure of the laser. A variable gain instrumentation amplifier is coupled to the generating apparatus and utilized to measure the optical output power of the laser transmitter.
