Patent CA-2397856-C (CA)
Title: Stroller with spring-biased brake pins
Inventor: LAN RED
IPC: B62B7/04
Filed: 2002-08-13
Granted: 2005-05-24
Abstract: A stroller includes a frame assembly with a pedal-mounting rod, on which a brake pedal is mounted rotatably. When the brake pedal is turned downward, a coupling mechanism activates two resilient elements to bias two brake pins to project from two pin holes in two mounting seats. At this time, in case the brake pins are aligned with two of a plurality of brake holes in two rear wheels, they are biased into the two brake holes. In case the brake pins are deflected from all of the brake holes, they are biased to press against the surfaces of the rear wheels. Under such conditions, the rear wheels are rotated slowly by pushing the stroller so as to permit the brake pins to be biased into two of the brake holes.

Abstract: A colored music notation system and a method of colorizing music notation using seven colors that are easily distinguishable from one another, representing the seven unique notes in an octave. The color of a note may be chosen from a list of colors in CMYK format, with a tolerance of plus or minus ten points, preferably plus or minus five points in attributes for any of the colors. The colors may be reproduced by any printing method, including using a conventional personal computer. The colors are easily reproducible within acceptable tolerances on a wide variety of media and with a range of printing options, can be read under various lighting conditions, and do not make written music unpleasant to the eye. The colors are also sufficiently different to allow for easy recognition of common chord combinations by the recollection of simple groups of colors. In the preferred embodiment of the invention, notes affected by an accidental are the same color as the natural note to which they are related. The invention also provides a method for applying color to the keys a keyboard instrument.

Title: Active reduction of tool borne noise in a sonic logging tool
Inventor: PABON JAHIR
IPC: G01V1/48
Filed: 2003-08-25
Granted: 2014-09-30
Abstract: A sonic logging tool that can be positioned within a fluid-filled borehole includes an axially distributed active vibration control system to reduce tool borne noise. The tool includes an acoustic transmitter, an axial array of acoustic receivers, and actuator assemblies that are coupled to cancel tool mode vibrations at stations along the receiver section of the tool. In a preferred embodiment, force is applied in feedback mode based on tool mode vibrations sensed at each station. The force at each station is applied by a real-time computational algorithm using feedback. The feedback includes weighting to accommodate monopole or dipole tool mode vibration. The computational algorithm includes FIR processing of signals received from a vibration sensor assembly. The force applied at a given station is a function of tool mode vibration measured at that station and the predetermined values of a set of FIR filter coefficients associated with the given station. The predetermined FIR filter coefficients are determined by an iterative optimization technique. Alternatively, the force at each station may be applied using feed-forward.

Abstract: In accordance with various aspects, the present invention relates to methods and systems for sending an identity information document comprising selecting identity information from a self-identity information store for inclusion in the identity information document. The selected identity information is read from a self-identity information store. The identity information document is generated to include the selected identity information and one or more keys, and signed using a key associated with one of the keys included in the identity information document. The identity information document is then sent to a recipient. Receiving an identity information document comprises receiving a signed identity information document from an originator. A determination is made as to whether identity information in the identity information document is reliable. The identity information is saved in a recognized identity information store if the identity information is determined to be reliable. If the identity information is determined to be unreliable, an identity recognition number retrieved from the sender is compared to an identity recognition number generated by the recipient based on information in the received identity information document. If the identity recognition number is verified, the identity information is saved in the recognized identity information store.
