Inventor: MALENFANT MARTIN
IPC: H05B43/00
Filed: 1997-11-03
Abstract: A lamp comprises (a) a set of light-emitting diodes each having a non linear voltage/current characteristic, (b) a source for supplying the set of light-emitting diodes with a dc voltage, and a feedback-controlled dc current varying non linearly with the dc voltage, and (c) a controller circuit responsive to an input voltage feedback signal for controlling the amplitude of the dc voltage. The lamp's improvement comprises a current-to-voltage converter for converting the dc current to a current-representative voltage signal, and a linearizing circuit. This linearizing circuit consists of passive filtering components having respective impedance values related to the non linear voltage/current characteristic of the light-emitting diodes for producing, in response to the current-representative voltage signal, the input voltage feedback signal varying linearly with the dc voltage although the dc current varies non linearly with the dc voltage. More specifically, the passive filtering components comprise a resistor having a first terminal receiving the current-representative voltage signal and a second terminal connected to an input of the controller circuit, and a capacitor having a first terminal connected to the resistor's second terminal and a second terminal connected to the ground. Accordingly, the input voltage feedback signal is produced on the interconnected resistor's second terminal and capacitor's first terminal.

Title: Novel uses for thyroid hormones or thyroid hormone-like compounds
Inventor: LAVIN THOMAS N
IPC: A61K31/19
Filed: 1996-06-07
Abstract: This invention relates to the use of topically applied thyroid hormones and thyroid hormone-like compounds which are receptor binding ligands, either agonists or antagonists, to improve the appearance of the skin and underlying subcutaneous fat and improve certain medical conditions when applied topically. These compounds can be used to treat skin conditions such as stria, cellulite, roughened skin, actinic skin damage, intrinsically aged skin, photodamaged skin, lichen planus, ichthyosis, acne, psoriasis, wrinkled skin, and to diminish the size and improve the appearance of skin scarring from surgical or naturally occurring wounds, and to reduce the incidence of hyperkeratotic scarring. These hormones or hormone analogs will also increase the rate of epithelialization and collagen production. The thyroid agonists and antagonists may also promote differentiation and amelioration of dedifferentiated skin in premalignant lesions. The thyroid agonists and antagonists can be active in all organisms which contain the thyroid hormone receptors, notably amphibians, birds and subjects. Combination with Vitamin D analogs glucocorticoid and retinoids will potentiateand modify the effects of the thyroid hormones for increased benefit.  Side effects of thyroid hormones which occur when the hormone is given orally and prevent usefulness for the above conditions are prevented when the hormone is topically applied.

Patent CA-2224951-A1 (CA)
Inventor: MCMILLEN TROY A
IPC: A61B17/04
Filed: 1997-12-16
Abstract: A device for forming a non-slip surgical knot for fastening tissue is disclosed. A partially tied knot which has a first loop and knot loops formed about the first loop to create a common loop core receiving the first loop is initially provided. The distal end of the suture filament from which the partially tied knot is made is passed through the tissue, and it is then fed through the first loop to form a tissue-fastening loop. When axial tension is applied on the proximal length of the suture filament while the knot loops are supported during the conversion step, the first loop and a portion of the suture filament are pulled through the common loop core. This eliminates the first loop and forms a distal loop positioned adjacent the common loop core. The device forms a non-slip knot, with a consistently high knot security without the need to provide a tension on the suture filament which exceeds the breaking strength of the suture.

Title: Integrated self diagnostic control system
Inventor: HALEY MAC
IPC: G05B19/05
Filed: 1997-12-22
Abstract: A self diagnostic system is integrated into an application program for controlling a machine or process. The application program is comprised of various logical segments that have to be solved by a logic solving engine. The diagnostic program will annunciate an event when the application program cannot execute a desired response by monitoring certain preselected and marked segments of the application program and allocating memory to save the result.. When an abnormal occurrence in these segments results in the desired event not occurring, the diagnostic system will determine what part of the logic expression controlling the event could not be completed. This information will be saved and used for annunciating the reason for the desired event not happening. The diagnostic system includes a special control module that is added to the application program.  This module is implemented as either an instruction added to the marked logic segment that is to be monitored in the case of a ladder logic system or as a subroutine as part of other types of sequential control methods. The data is recorded automatically, without application programming.
Patent CA-2230434-A1 (CA)
Inventor: ERCAN GURCHAN
IPC: G06V10/28
Filed: 1998-02-24
Abstract: A method of processing digital image information, including pixel intensity information, includes the steps of identifying a region of the image in which pixel intensities are similar to each other, but the median pixel intensity differs significantly from the median pixel intensity of other parts of the image; and modifying pixel intensities in the identified region so that the median for the region is closer to the median for the other parts of the image.      A related method of processing digital image information involves modifying pixel intensities according to a non-linear algorithm, with the result that one or more regions of the image have their median pixel intensities adjusted to a level which is closer to the median pixel intensity for other parts of the image. A composite digital image can be formed by obtaining first and second digital images of the same scene but with different exposure or light reception conditions so that one of the digital images has higher pixel intensity values than the other; identifying one or more regions on the first image which are less clear than the corresponding regions on the second image; and replacing the identifiedregions or the first image with the corresponding regions of the second image.

Title: Grating-assisted fused fiber filter
Inventor: LAUZON JOCELYN
IPC: G02B6/34
Filed: 1998-04-14
Abstract: A fused fiber filter coupler is disclosed characterized in that a long period grating is written in at least a portion of the waist of the coupler. The two fibers which make up the coupler have respective propagation constants .beta.fiber1 and .beta.fiber2 which are different and both fibers are singlemode at the wavelength of operation. In order for an efficient grating to be written in the waist of the coupler, the coupler must be photosensitive in at least a region of the waist. Since the propagation constant is a function of the wavelength and the period of the grating is given by the expression ~ = 2.pi.(.beta.fiber1 -.beta.fiber2), the filter may be tuned to a particular wavelength by adjusting the period of the grating. The filter so constructed acts in transmission and can discriminate wavelengths of the order of 1 nm. The filter is particularly useful in wavelength-rich optical communications networks to extract a particular wavelength from a signal or to add a particular wavelength to a signal (i.e. multiplexing and demultiplexing).

Abstract: For a better recognition of unrolled images of fingerprints, a picture is taken of the skin lines of two adjacent fingers (1, 2). The directions of both finger length axis (L1, L2) are determined according to an N standard direction and a guiding device (13) prevents fingers from rotating about their length axis, thereby allowing for a number of definite and substantially consistent partial images (B3, B4) of the completely unrolled fingerprint (A) to be captured and those images to be converted on the basis of assessment algorithms into a lowered data quantity, thus significantly improving recognition reliability, reducing the storage capacity needed and simplifying the assessment algorithms.

Title: Dsp decoder for decoding analog sr encoded audio signals
Inventor: BARNES CASPER W
IPC: G11B20/10
Filed: 1996-11-22
Abstract: A decoder capable of decoding audio signals encoded using analog noise reduction techniques, particularly Dolby SR, is implemented by means of digital signal processing. The typical decoding paradigm used by analog Dolby SR decoders is modified to overcome the problems caused by delay which is introduced by the digital implementation. A gain factor is factored out of the feedback transfer function and is placed in the forward signal path of each stage of the digital decoder. A single control circuit can then be used to generate coefficients which define transfer functions of each filter stage of the signal path. Linear interpolation techniques are used to limit the number of coefficient entries necessary to emulate the transfer function of an analog Dolby SR decoder. The digital decoder structure can be inverted to produce a digital encoder which is capable of implementing any noise reduction standard desired, including Dolby SR.

Title: System and method for storing and processing date information capable of spanning centuries
Inventor: CHAMBERS ROBERT M
IPC: G06F1/14
Filed: 1998-05-20
Abstract: A system for reading and writing overloaded dates is provided in which six digits are used to represent dates including century information in a manner which maintains sorting and indexing. A three digit prefix is determined from the year and century information using windowing if necessary, and a three digit suffix is determined from the day and month information. Furthermore, a system for reading and writing overloaded Julian dates is provided in which five digits are used to represent dates including century information in a manner which maintains sorting and indexing. An offset value is created by multiplying the maximum number of days in any year (plus 1), being 367, by the number of the year in the Julian date then adding the day portion. The year is windowed to derive a century that if true requires a value greater than 99 x 367 (36333) be added to the offset value to indicate a subsequent century. The process is revised to interpret such a date.
