Patent CA-2142398-A1 (CA)
Inventor: CHEN JUIN-HWEY
IPC: G10L19/00
Filed: 1995-02-13
Abstract: A speech coding system robust to frame erasure (or packet loss) is described. Illustrative embodiments are directed to a modified version of CCITT standard G.728. In the event of frame erasure, vectors of an excitation signal are synthesized based on previously stored excitation signal vectors generated during non-erased frames. This synthesis differs for voiced and non-voiced speech. During erased frames, linear prediction filter coefficients are synthesized as a weighted extrapolation of a set of linear prediction filter coefficients determined during non-erased frames. The weighting factor is a number less than 1. This weighting accomplishes a bandwidth-expansion of peaks in the frequency response of a linear predictive filter. Computational complexity during erased frames is reduced through the elimination of certain computations needed during non-erased frames only. This reduction in computational complexity offsets additional computation required for excitation signal synthesis and linear prediction filter coefficient generation during erased frames.

Title: Continuous Preparation of Non-Aggregated Edible Cores with Crisp Farinaceous Coatings
Inventor: LANNER DAVID ARTHUR
IPC: A23L25/00
Filed: 1994-02-10
Abstract: A tumbling bed of edible cores is formed which has a longitudinal axis extending from an entrance end to an exit end of the tumbling bed. Individual edible cores travel through the tumbling bed from the entrance end to the exit end by rotating in a generally helical path along the longitudinal axis of the bed. The edible cores are coated within the bed by repeatedly tumbling through both a wet zone(s) and a dry zone(s) formed within the bed. These wet and dry zones are formed, respectively, by spraying the surface of the tumbling bed with a hydrating liquid and by dusting the surface of the tumbling bed with a farinaceous powder. Both the wet and dry zones thus formed are generally rectangular, but not overlapping zones with the major dimensions  of these rectangular zones being substantially parallel to the longitudinal axis of the tumbling bed. Hydrating liquid and farinaceous powder are applied, respectively, to the wet and dry zones of the tumbling bed at rates which prevent aggregation of the edible cores and at rates which are suitable to form on the cores a dough-coating comprising flour, starch and sugar in a weight ratio of flour and starch to sugar of from about 05:1 to 30:1. The dough-coated edible cores are then cooked until crisp.

Title: Method of fabricating a preform for an amplifying optical waveguide, and an optical waveguide
Inventor: WEBER DIETER
IPC: C03C13/04
Filed: 1994-02-05
Abstract: There is a considerable need for optical fibre amplifiers for the wavelength range around 1300 nm for information transmission. The basic material for the amplifier light guide (10) needed therefor is to be silicon dioxide. The doping agents neodym and praseodym normally used for the desired wavelength range are, however, not suitable as they stand to obtain the required amplification.  According to the invention, neodym or praseodym is used in combination with fluorine, preferably as the compound NdF3 or PrF3. In a preferred production process, an easily evaporable complex is formed from NdP3 and a further compound, e.g. AIF3, and taken in vapour form to a substrate for a deposition from the vapour phase.

Title: Duplicated arrangement for atm switching system
Inventor: KURANO TAKATOSHI
IPC: H04L12/70
Filed: 1995-11-06
Abstract: In a duplicated arrangement for an ATM switching system, first and second store-and-forward buffers are provided for storing and forwarding an ATM cell stream and first and second counters are responsive to a timing signal for producing a first cell count and a second cell count representative of counts of cells stored in the first and second store-and-forward buffers, respectively. A detector is provided for detecting a difference between the first and second cell counts. A buffer controller controls the second store-and-forward buffer in accordance with the difference so that the count of cells in the second buffer approaches the count of cells in the first buffer. A protection switching circuit normally couples the ATM cell stream forwarded from the first buffer to an output port of the ATM switching system and coupling the ATM cell stream forwarded from the second buffer, instead of from the first buffer, to the output port in the event of a failure in the system.
Patent CA-2164039-A1 (CA)
Inventor: SEWELL FREDERIC D
IPC: F24F3/14
Filed: 1995-11-29
Abstract: An automatically controlled water spray-based air purification system having a humidification portion and a dehumidifying portion is operatively installed in an air handling unit used to recirculate air within a conditioned space.  A blower within the air handling unit housing operates to draw return air into the housing, flow the air across the entire air purification system, and then discharge the purified and humidified air back into the conditioned space. Upon sensing an excess humidification of the air, a humidistat operates a supply air/return air damper system to cause a portion of the air interiorly traversing the housing to bypass the humidification portion of the purification to thereby reduce the moisture content of the air discharged from the unit. A water spray portion of the purification system is served by a pump forcing water from a sump structure through a filter, with the spray water draining back into the sump after cleansing air traversing the purification system.  Upon a sensed demand therefor, an additive injector adds suitable chemical treatment material to the sump water, and a water pollutant monitor structure operates to backwash the filter upon sensing an undesirable pump back pressure increase or a buildup of particulate and gaseous pollutants in the sump water.

Patent CA-2170441-A1 (CA)
Title: Identification Card Verification System and Method
Inventor: KRISTOL DAVID MORRIS
IPC: G07F7/12
Filed: 1996-02-27
Abstract: A self-verifying identification card having an image area which may contain a portrait, a finger print, a retinal image, or all of these together with an image signature which is derived from scanned intensity measurements taken from the image area.  In the verification process, the image is scanned and aligned with respect to reference points corresponding to the original printing process which created the card, and intensity values, their averages, or any other function are compared to information provided by the image signature.  Mathematical transformations, such as a one-way hash, an encryption, a compression algorithm, or a truth table may be used to encode the image signature. Alignment markers aid in scanning the image and the image signature.  The use of average values aids in reducing noise and the use of comparison functions makes the process less sensitive to variations among scanners.  The verification may be done at the point of a transaction, for a standalone system, or may be referred to a centralized data base in a networked system for further inquiry.  In a networked system the image signature may be stored in the database.
