Patent CA-2097515-C (CA)
Title: Fiber orientation sensor
Inventor: CHASE LEE M
IPC: G01L5/10
Filed: 1991-12-18
Granted: 2000-09-19
Abstract: A sensor (10) for detecting directional variations in a physical characteristic, fiber orientation angle and the degree of anisotropism of a moving sheet of material is disclosed. The sensor (10) has a support (12) for supporting the moving sheet (14). The support (12) defines an open region into which the moving sheet (14) is deflected by a deflector (16). Detectors (20) coupled to the support (12) detect and produce signals indicative of the force exerted on the support (12) by the deflected sheet in at least three different directions. Alternatively, the support (112) may be rotatable to allow detectors (120) coupled to the support (112) to detect and produce signals indicative of the force exerted on the support (112) by the deflected sheet (114) in a number of different directions. Each signal is processed to determine a physical characteristic, such as extensional stiffness, of the sheet of material in each of the at least three directions.

Abstract: A cashless gaming apparatus and method suitable for casinos. A player hands over money and an ID card to a clerk at a validation terminal. The clerk stores the ID number and the amount of money in the memory of the validation terminal. Then the clerk returns the ID card to the player for operating any one of a number of game terminals. The player then selects a game terminal which reads the player's ID card, whereupon the cash amount from the validation terminal is downloaded to the selected game terminal and the game terminal can then be played. If the player wishes to play another game terminal, the player actuates a cashout switch on the current terminal. The player then moves to another game terminal and the player's ID card is read into the second game terminal, whereupon the money remaining as a cash amount is downloaded to the second game terminal. The player can then play the second game terminal. When the player wishes to stop play of the game terminals completely, the player actuates the cashout switch of the last game terminal played. The player presents his ID card to the clerk at the validation terminal and the validation terminal reads the ID card. A ticket showing the card number and the cash amount is printed and the player is paid the cash amount on the spot. The printed ticket is then used for reconciliation.

Granted: 1995-07-18
Abstract: The ride (10) is capable of raising a rider (22) to a height of ten meters or more above the ground, and then releasing the rider to swing. It includes a support structure (12), a support line (16) secured to the support structure at one end, with an op-posed end secured to a rider, preferably to an attachment which is worn by a rider (20). A launch structure (26) is spaced from the support structure (12) and carries a launch line (24) which has an end (48) which is capable of being raised and lowered above the ground, and which is designed to be releasably attached to a rider attachment, so as to lift a rider from the ground. In operation the rider attachment with the support line attached is secured to the rider, the launch line is releasably secured to the attachment, and the launch line is activated to move the rider laterally and upwardly towards the top of the launch structure. When the launch line is released from the attachment which carries the rider, the rider swings downwardly at a high speed simulating the sensation of "body flight" in a pendulum like motion.

Patent CA-2174159-C (CA)
Inventor: SHAW DAVID GOODWIN
IPC: G10L21/0208
Filed: 1996-04-15
Granted: 2001-08-07
Abstract: Acoustic echos are canceled by employing a first echo canceler having a comparatively long first impulse response synthesis capability which is connected between a transmit path and receive path for generating  a first error signal and for canceling echo signals in the transmit path, and at least a second echo canceler having a comparatively short second impulse response synthesis capability connected in parallel with the first echo canceler between the transmit and the receive path.  The second echo canceler is supplied with the first error signal from the first echo canceler and is adaptively operating simultaneously with but independent of the first echo canceler to further cancel echos in the transmit path.  Specifically, the first echo canceler is intended to capture the substantially stationary and any  slowly  varying  components of the echo path impulse response, and the second echo canceler is intended to capture the more time varying, i.e., dynamically varying, component of the echo path impulse response.  I have recognized that in certain applications, the more time varying component of the echo path impulse response may exist in a relatively short time interval. For  instance, in the canceling of acoustic echos, the most time variation in the echo path impulse response results from the movement of objects and/or persons near either the microphone or the loudspeaker.   This movement results in significant changes in the early portion of the echo path impulse response.  Aligning the tap coefficients of the second echo canceler with this early portion of the echo path impulse response provides significantly enhanced echo cancelation  performance  over that achievable with only the first echo canceler. This is realized by placing a "short" fixed delay in series with the receive path signal to the second echo canceler. In other applications, the time varying component of the echo path impulse response still exists in a relatively short time interval, but the time varying component  relative to the overall echo path impulse response may change with time or may not be known a priori. Under these circumstances,  it is desirable to dynamically align the coefficients of the second echo canceler over the echo path impulse response. This is realized by employing a dynamically adjustable delay in series with the receive path to the second echo canceler. In one embodiment, the delay value is dynamically generated in response to the tap coefficient values of the first echo canceler.
