Patent CA-2471142-A1 (CA)
Title: Ressort a comportement controle
Inventor: MARCOTTE PIERRE
IPC: G05D15/00
Filed: 2004-06-25
Abstract: Ressort dont le comportement est régi par un actionneur qui en contrôle soit l'impédance, soit la force de contact. Une extrémité du ressort est fixe et l'autre est mobile. Le rôle de l'actionneur est d'appliquer une force sur l'extrémité mobile, laquelle forc e est calculée par un contrôleur. Le ressort est muni de capteurs de force, de position et facultativement d'accélération générant des signaux dont se sert le contrôleur pour effectue r ses calculs. Lorsqu'un objet entre en contact avec l'extrémité mobile et qu'une force extérieure est appliquée, le ressort réagit selon le mode de fonctionnement en opération. E n mode force, la force de contact est contrôlée et en mode impédance, l'impédance est contrôlée. Un tel ressort offre la possibilité de varier sa dynamique d'interaction avec son environnement. ~ titre d'exemple, il peut servir d'engin acrobatique pour la propulsion ou la réception d'acrobate ou comme suspension active d'un véhicule automobile.

Title: Earphone structure with a composite sound field
Inventor: YANG BILL
IPC: A61F11/06
Filed: 2004-07-30
Abstract: An earphone structure including one or more composite chambers is described. Each of the composite chambers includes sub-speakers. The sounds generated by these sub-speakers are uniformly distributed in the composite chamber and a composite sound field is generated by these sub-speakers. The sound field generated by each of these sub-speakers can be adjusted by re-locating the position of the sub-speaker, for example, by re-locating the sub-speaker, or by re-locating the sub-speaker in different angles, to generate the composite sound field. The sound field generated by the main speaker and the composite sound field generated by these sub-speakers can form a spatial sound with very good quality. By using of its physical characteristics of locations of these sub-speakers, the sound generated by the earphone has an uniformly diffusion sound pressure and a surround effect, which allows a user of the earphone to enjoy a sound field similar to that in a theater.

Title: Directional controller for a hearing aid
Inventor: JENSEN LARS BAEKGAARD
IPC: H04R1/32
Filed: 2000-06-23
Abstract: Change-over of the sound receiving characteristic of a hearing aid having spaced apart first and second microphone means (Fmic, Bmic) between the omnidirectional characteristic and a directional characteristic is effected by controlled attenuation and time or phase delay of signals derived from the signals (X front, X back) from the first and second microphone means before forming and overall combined signal (y) to be supplied to the hearing aid signal processor, whereby the overall combined signal (Y) is determined by Y = X front * (1 - omni * e-j.omega.T) + X back * (omni - e -j.omega.T) , where omni is an adjustable attenuation control parameter preferably in the range 0 <= omni <= 1 and T is a time delay corresponding to the acoustical delay between the first and second microphone means. In result, the change between the omnidirectional characteristic and any desired form of the directional characteristic is effected as a smooth change-over substantially without affecting phase relationship. Time delay and amplitude characteristic of the hearing aid.

Title: Detection of ferromagnetic objects approaching a magnet
Inventor: HOULT DAVID I
IPC: F02P17/00
Filed: 2003-04-15
Abstract: An apparatus for detecting a potentially dangerous ferromagnetic object carried inadvertently by a person approaching the magnet of a magnetic resonance imaging system uses the fringe field of the magnet and provides guide members defining a path along which the person is prescribed to pass. The path is generally or approximately parallel to the field at the path. At least one sense coil and generally two sets of sense coils are located on respective sides of the path so that the movement of the ferromagnetic object in the field of the magnet causes a voltage to be generated in the sense coil. The sense coils include vertical coil legs on each side of the path at spaced positions along the path defining a sensing zone having a height approximating the height to be sensed. An electrical measuring device measures the electrical signal and provides a warning indication when the electrical signal exceeds a predetermined value, either by its amplitude or by an integral over the movement of the person within the zone as detected by an independent sensor which senses entry into and exit from the zone.

Title: Efficient venting means for a circuit breaker
Inventor: FLEEGE DENNIS W
IPC: H01H73/06
Filed: 2005-03-31
Abstract: An arrangement for reducing pressure inside a circuit breaker caused by gas produced during an electrical interruption event, including a base, an interrupter assembly, and a trip unit base. A structure having a surface is positioned in the base at an angle relative to a vent opening of the interrupter assembly. The trip unit base includes a complementary structure opposing the structure to form a cavity. The base includes a chamber area adjacent to an opening of a vent chute that leads away from the circuit breaker. During an electrical interruption event, hot explosive gas, carbon, and molten metal debris are directed away from the vent opening of the interrupter assembly along the angled surface of the structure and toward the opening of the vent chute. In this manner, pressure in the circuit breaker is reduced during an electrical interruption event, and undesirable buildup of debris is reduced.

IPC: D21H17/27
Filed: 2005-05-27
Abstract: A method for making an opacity relevant grade paper or paperboard product, such as a communication type paper used for printing and writing applications, utilizes an effective amount of quaternized alkanolamine fatty acid ester compounds as an opacification aid to control the optical properties of the paper or paperboard product as a wet-end additive to a papermaking operation. Using the quaternized alkanolamine fatty acid ester compound can improve the opacity of the paper or paperboard product, maintain the opacity of the paper while reducing the use of other opacification aids, such as inorganic fillers and/or pigments, and allow for a reduction in paper grammage without a compromise in opacity. The improvements in paper optical properties are achieved without adversely affecting other characteristics of the paper product such as bulk value, tensile strength, tear index, and the like.
