Title: Apparatus and Method for Adaptive Suppression of Vibrations in Mechanical Systems
Inventor: BENNING ROGER DAVID
IPC: G05B13/02
Filed: 1997-02-17
Abstract: A method and apparatus are provided for stabilizing at least one element of a mechanical system against echo-like responses to mechanical disturbances.  One or more error signals are provided by sensing the motion of the system at one or more points. At least one adaptive filter is operated in response to the error signal or signals, and in response to at least one non-advanced reference signal that is directly related to some motion of the system. The adaptive filter produces a corrective signal for driving a mechanical actuator, thereby to apply to the element a stabilizing generalized force. By non-advanced is meant that there is a zero or negative time-delay between the presence of a given signal at the reference-sensing location and the arrival of the same, or a similar, signal at the error-sensing location.  In particular embodiments of the invention, the reference-sensing location is the same as the error-sensing location.

Filed: 1995-08-16
Abstract: The invention is directed to a brush section (1) for an electric toothbrush, which includes a mounting tube (2) in which a shaft (7) arranged in the direction of a longitudinal axis (3) is received. Two bristle carriers (14, 15) are mounted for rotation about associated brush axes (24, 25). Further, means are provided, in particular two connecting rods (30, 31), to effect coupling engagement of the shaft (7) with the two bristle carriers (14, 15), such that a motion (36) of the shaft (7) effects a rotary motion (37, 38) of the two bristle carriers (14, 15) about the two brush axes (24, 25) . The two brush axes (24,25) are arranged in a plane approximately at right angles to the longitudinal axis (3) and define between them an approximately right angle. In this arrangement, the motion of the shaft may be a rotary motion about the longitudinal axis (3) or a longitudinal motion in the direction of the longitudinal axis (3).      Still further, the bristle carriers (14, 15) may be pivotally arranged by means of arms (60, 61), utilizing in particular the longitudinal axis (3) as pivot axis.
Patent CA-2203953-A1 (CA)
Inventor: SIMON ROBERT J
IPC: B41J2/165
Filed: 1997-04-29
Abstract: Ink concentration changes in continuous ink jet printing systems have been minimized by reducing evaporation rates. This has the effect of also minimizing airflow through the catcher The reduced catcher flow is not capable of completely removing air around the jets when the eyelid is closed, so this air becomes saturated with water vapor due to localized evaporation from ink drops. This, in turn, causes the air temperature to approach the ink temperature, which is greater than the eyelid seal temperature. The saturated air condenses on the eyelid and, over time, the condensate fills the volume and drips out of the eyelid, or causes shorts to the high voltage electrode. The formation of condensate on the eyelid is eliminated by providing a heater element formed into the eyelid.

Title: Optical communications system employing spectrally sliced optical source
Inventor: KOREN UZIEL
IPC: H04B10/272
Filed: 1997-07-02
Abstract: An apparatus and method provides optical multiple wavelength signals using a single, broadband optical source such, for example, as an LED, to generate many independent optical wavelength channels. An optical transmitter includes a wavelength channel defining assembly which resolves the broad spectrum pulses output by the source into discrete wavelength bands constituting respective pulses (i.e., wavelength channels) and which inserts a delay between the bands to define a sequence of individually addressable channels. In accordance with one embodiment of the invention, spectral splicing is achieved by a multiple channel filter, and insertion of the respective delays is achieved by individual fiber sections, each section having a length selected to introduce a particular delay, coupled to the output ports of the router. The inserted delays can be conveniently selected to separate adjacent wavelength channels and thereby minimize the likelihood of crosstalk. Pulses of the thus-resolved channels arrive at different times to a multiplexer which may be configured, for example, as a passive WDM multiplexer or as a star combiner. The resulting sequence of addressable wavelength channels may be supplied to one or more high-speed, broadband modulators, with each modulator being operable to modulate some or all of the channels.

Patent CA-2230573-A1 (CA)
Inventor: MCLEOD GAVIN THOMAS
IPC: E21B23/03
Filed: 1996-08-27
Abstract: Locking system (196) is provided for selectively locking an external sleeve (76) to a main body (74) of a downhole tool (14). Locking system (196) comprises a pair of opposed holes (198) formed in the main body (74). The holes (198) capture respective locking balls (200). A channel (210) extends from each hole (198) longitudinally about the outer surface of the main body (74). A spring (206) held within the main body (74) acts to push the balls (200) out of holes (198). Openings (212) are also formed in the sleeve (76) and disposed so that the balls (200) can protrude therethrough and contact the inner circumferential surface (28) of a drive sub (12) by virtue of the bias of spring (206). When the internal diameter of the drive sub (12) is relatively small, the balls (200) are pushed inwardly against the spring (206) and reside, at least partially, within holes (198). This prevents the balls from moving longitudinally about channels (210) thereby locking the sleeve (76) to the main body (74). However, when the internal diameter of the drive sub increases, the balls (200) are pushed radially outwardly by the spring (206) to the extent that they can then escape holes (198) and roll along channels (210). This allows the sleeve (76) to slide relative to the body (74).

Inventor: VANSTONE SCOTT A
IPC: H04L9/30
Filed: 1998-03-25
Abstract: A method for multiplication of a point P on elliptic curve E by a value k in order to derive a point kP comprises the steps of representing the number k as vector of binary digits stored in a register and forming a sequence of point pairs (P1, P2) wherein the point pairs differed most by P and wherein the successive series of point pairs are selected either by computing (2mP,(2m+1)P) from (mP,(m+1)P) or ((2m+1)P,(2m+2)P) from (mP,(m+1)P). The computations may be performed without using the y-coordinate of the points during the computation while allowing the y-coordinate to be extracted at the end of the computations, thus, avoiding the use of inversion operations during the computation and therefore, speeding up the cryptographic processor functions. A method is also disclosed for accelerating signature verification between two parties.
