Patent CA-2236255-A1 (CA)
Title: Ultrasonic energy delivery system and method
Inventor: CASTELLANO THOMAS M
IPC: A61B18/00
Filed: 1997-09-09
Abstract: An energy delivery system and method control the frequency of the power driving an ultrasonic device (24) to achieve more efficient power delivery. During operation of the ultrasonic device to deliver power to a patient site (16), the system and method automatically sweep the drive power through a frequency range, locate the series and parallel resonance frequencies, calculate the average of those frequencies and lock the power generator at that average frequency to drive the crystal. This frequency sweep procedure occurs automatically when the ultrasonic crystal is located at the patient site and the power generator operator presses the power-on switch to apply power. The method of tuning the power generator thus occurs when the crystal is at the site temperature and is transparent to the operator. The application of an external bio-layer to the crystal increases its bandwidth and its robustness. Mounting a temperature sensor (28) or sensors at the crystal permits monitoring of the crystal temperature and allows drive level control over the power generator to control the temperature at the crystal.

Patent CA-2254538-A1 (CA)
Inventor: REIMER ERNEST M
IPC: G01L5/00
Filed: 1998-11-26
Abstract: A collision deformation sensor for use within the crush zone of a vehicle consists of first and second spaced apart substrates for mounting to respective vehicle components, with a compressible carrier medium filling the space between the substrates. The carrier medium includes wave energy scattering centers dispersed within the medium to create a scattered energy volume, or alternatively a cavity, the inside surface of which is coated with a wave energy dispersion coating. A source and receiver of light or other wave energy communicates with the interior space. Single coupling and single processors are associated with the wave energy transmitters and receivers. The device operates on the principle whereby compression of the space between the substrates increases the intensity of a light or other wave energy, and this increase is detected by the receiver and signal processor, which in turn activates an air bag, or seat belt tightener or the like.
Patent CA-2254634-A1 (CA)
Title: Metallic fastening member and fabrication method thereof
Inventor: NAGAYAMA YUTAKA
IPC: F16B37/04
Filed: 1998-11-27
Abstract: A metallic fastening member of a one piece configuration formed of a metal material includes a shaft portion (32) and a flange portion (33) extruding outwards from a first end of the shaft portion. The shaft portion (32) includes a relatively thin-walled portion (34) to be caulked at a second end opposite to the first end. A female thread (36) is formed at an inner peripheral face of the shaft portion excluding the portion to be caulked (34). An annular groove (50) is formed at an outer peripheral face of the shaft portion (32) or at the inner peripheral face of the portion to be caulked (34), so that the shaft portion (32) has a partially thin wall. Since the wall of the shaft portion (32) is thinner at the annular groove (50), the metallic fastening member is fractured at that area to be separated into upper and lower pieces in the work of detaching the metallic fastening member from an object of fixation. Therefore, the metallic fastening member can be readily removed from the object of fixation to facilitate the recovery work for recycling purposes.

Abstract: A drive transmission for the feed rolls of a forage harvester includes a planetary gear set arranged such that an input shaft drives the sun gear while a further input shaft is provided by a reversible, variable speed motor that is connected to the ring gear of the planetary gear set so as to effect speed and direction changes in the output of the planetary gear set that is defined by the planet carrier. Thus, the length of cut of crop products fed to the cutterhead by the feed rolls is controlled by varying the speed of the motor in order to vary the delivery speed of the feed rolls.
