Patent CA-2133292-A1 (CA)
Title: Tamper-evident closure
Inventor: DECELLES GILLES
IPC: B65D41/38
Filed: 1994-09-29
Abstract: A  tamper-evident  closure  is  disclosed  to  seal  a container having a threaded neck portion and an outwardly extending  annular  flange  adjacent  to  and  beneath  the threaded neck portion. The closure comprises a cap portion and a ring portion. The cap portion has a top wall and an annular skirt. The ring portion comprising an upper ring, a lower ring and a plurality of inwardly oriented wedges positioned between the upper and lower ring.   The ring portion is connected to the lower edge of the skirt so as to be easily breakable.  The plurality of inwardly oriented wedges are circumferentially distributed and spaced apart from each other between the upper and lower ring. Each wedge has an upper and lower edge connected along a thin folding lines to the lower and upper ring. Each wedge also has an inwardly and upwardly projecting apex positioned and sized to fit under the outwardly extending flange of the threaded neck portion of the container when the cap portion of the closure is fully screwed onto the threaded neck portion. In use, when the closure is screwed onto the container, the wedges are allowed to move radially outwardly thanks to the thin folding lines joining the wedges to upper and lower ring and thus the wedges pass over the flange of the neck. Then, the wedges return to their original position where the apexes extend under the flange. As soon as someone tries to remove the closure, the apexes of the wedges engage the flange of the neck and get lock onto the same, thereby causing the ring portion to separate from the skirt of the cap portion and fall, thereby providing an indication that the container has been open.

Patent CA-2141624-A1 (CA)
Title: Lift Truck Diagnostics
Inventor: SIMMONS JAMES M JR
IPC: G01R31/00
Filed: 1995-02-01
Abstract: The present invention features a diagnostic method for assessing intermittent failures which occur in the components and systems of material handling vehicles.  The material handling vehicle of this invention uses an on-board microprocessor and display to allow an operator to determine whether any intermittency is present in the internal systems.  The microprocessor is programmed to analyze each system during normal vehicular operation.  The program is divided into two vehicular modes, "normal operating" and "program".  During the normal operating mode, the vehicle operator is warned of a problem by different audible tones and patterns.  A fault code scrolls across the vehicle display screen, indicating the nature of the failure.  The program mode can then be entered to assess just where the problem is located.  The program mode is divided into three additional modes: "maintenance mode", "configure mode" and "learn mode".  The vehicle is selected for maintenance diagnostics during the program mode, and then switched back to the normal operating mode, where the intermittent failures can be diagnosed.  The maintenance mode is divided into three diagnostic surveys: output controls, digital input measurements for analyzing switches and encoders, and analog input measurements for testing voltages and potentiometers.  Each system in the vehicle can be analyzed by selecting the proper maintenance code.

Title: Maximum-Likelihood Sequence Estimator with Variable Number of States
Inventor: USHIROKAWA AKIHISA
IPC: H04B3/10
Filed: 1995-07-06
Abstract: A maximum-likelihood sequence estimator (MLSE) with a variable number of states.  A channel response estimator calculates channel responses from a received signal having a predetermined burst length and a reference signal. A controller checks the latest (L-th) response having a larger power than a predetermined threshold value of the channel responses and determines the L number of effective channel responses having the larger power.  A Viterbi equilizer with a variable number of states executes a maximum-likelihood sequence estimation on the basis of the trellis with M(L-I) states (M is a multi-value number of a modulation signal) using the L number of effective channel responses.  The MLSE is operated with the minimum number of states every burst to reduce an average processing amount without degrading characteristics and to achieve a low consumption power of receivers.

Title: Low fat, low calorie fat substitute
Inventor: BATEMAN KRISTINE
IPC: A23L29/269
Filed: 1994-06-10
Abstract: A low fat, low calorie substitute fat food stuff emulsion and method for making the same is disclosed, the emulsion substantially simulating the appearance, taste, texture, and mouth feel of traditional fat-filled foods. The emulsion can be easily substituted in 1 to 1 proportions for butter, margarine, shortening, oil, lard, cream cheese and other fats called for in many foods. Because of the ease and simplicity of using the emulsion, people on fat restricted diets can now eat normal foods without substantially altering the recipe. The percentage of emulsion in the final food product simply depends on the percentage of fat in the original fat-filled food. By using butter or margarine in conjunction with maltodextrin, the emulsion (1) avoids the high fat found in lard and/or shortening (2) retains much if not all of the texture maintained by the fat, yet (3) incorporates more natural products, avoiding certain chemicals commercially produced as emulsifiers which are often used in conjunction with fat substitutes.

Title: Integrated low complexity broadband multi-channel switch
Inventor: SAIDI HOSSEIN
IPC: H04L47/43
Filed: 1994-04-22
Abstract: A multi-channel, multi-casting switch (20) for an ATM network utilizes a particular nonblocking condition of the Flip Network (28), which is exploited to realize a multi-channel switching architecture that supports an arbitrary number of channel groups. Using a single nip Network (28) recursively, the resulting architecture becomes efficient in the sense that the crosspoint complexity is O(N log2N) for N inputs. The number of times the Flip Network (28) is used recursively is a function of the number of channel groups only. The architecture is internally nonblocking and bufferless. In multi-channel switching cells belonging to a single session can traverse over multiple channels and the architecture maintains cells in order by assigning a specific Gray code to each data cell in each group.

Patent CA-2171927-A1 (CA)
Inventor: MACHIDA YUTAKA
IPC: H04N19/91
Filed: 1996-03-15
Abstract: Important quantized coefficients of which absolute values are higher than a threshold-value are extracted from each of quantized coefficient streams into which a digital image signal is transformed, and an important quantized coefficient stream composed of the important quantized coefficients and zero-valued quantized coefficients is produced on condition that the number of important quantized coefficients and zero-valued quantized coefficients is equal to that of quantized coefficients in each quantized coefficient stream and positions of the important quantized coefficients in the important quantized coefficient stream are the same as those in a corresponding quantized coefficient stream. Also, a lesser-important quantized coefficient stream is produced by subtracting the important quantized coefficient stream from the corresponding quantized coefficient stream. High precision type error correction codes are added to each important quantized coefficient stream and are transmitted to a decoding apparatus, and low precision type error correction codes are added to each lesser-important quantized coefficient stream and are transmitted to the decoding apparatus. Therefore, an image having a superior quality can be reproduced with a high code efficiency.
