Patent CA-3018488-A1 (CA)
Inventor: HERSHEY BRADLEY L
IPC: A61N1/00
Filed: 2017-02-10
Abstract: An Implantable Pulse Generator (IPG) is disclosed that is capable of sensing a degree to which recruited neurons in a patient's tissue are firing synchronously, and of modifying a stimulation program to promote desynchronicity and to reduce paresthesia.  An evoked compound action potential (ECAP) of the recruited neurons is sensed as a measure of synchronicity by at least one non-active electrode. An ECAP algorithm operable in the IPG assesses the shape of the ECAP and determines one or more ECAP shape parameters that indicate whether the recruited neurons are firing synchronously or desynchronously. If the shape parameters indicate significant synchronicity, the ECAP algorithm can adjust the stimulation program to promote desynchronous firing.

IPC: D21G9/00
Filed: 2018-07-19
Abstract: A method is provided for decision support in regulating an adhesive coating applied to Yankee dryers, since it can be difficult to quickly measure relevant process characteristics and subsequently predict the amount of natural coating available in real time.  Online sensors are configured to continuously measure stock characteristics, and additional sensors provide actual stock flow rate and machine speed. A controller predicts potential natural coating application from a fibrous sheet generated from the stock to the Yankee dryer surface, substantially in real time, based on the measured characteristics and sensed actual machine values. An optimal adhesive coating feed rate is determined and displayed for operator decision support. The controller in an automatic mode is configured to regulate the adhesive coating feed rate based on a comparison of one or more determined optimal values associated with respective actual values.
