Abstract: An inductive position detection configuration for stylus position measurement in a scanning probe comprises a stylus position detection portion arranged along a central axis in the probe. The stylus position detection portion includes a field generating coil configuration and top and bottom axial and rotary sensing coil configurations. The field generating coil configuration generates a changing magnetic flux, and coil signals indicate conductive disruptor element and/or stylus positions. A field generating coil coupling and crosstalk reducing configuration couples signal processing and control circuitry to the field generating coil configuration to provide a coil drive signal, and is configured to reduce crosstalk that would otherwise occur if the field generating coil configuration were directly connected to the signal processing and control circuitry without the field generating coil coupling and crosstalk reducing configuration.

Abstract: A peripheral nerve stimulator can be used to stimulate a peripheral nerve to treat essential tremor, Parkinsonian tremor, and other forms of tremor. The stimulator can have electrodes that are placed circumferentially around the patient's wrist or arm. Specific nerves in the wrist or arm can be targeted by appropriate spacing of the electrodes. Positioning the electrodes on generally opposing sides of the target nerve can result in improved stimulation of the nerve. The stimulation pattern may alternate between the nerves. Improved stimulation algorithms can incorporate tremor feedback, external data, predictive adaptation, and long-term monitoring data.

The dry electrodes may include a conductive base layer and a polymeric, plastic or rubber skin contact layer comprising a conductive filler. The filler may be a powder, fiber, conductive coating, etc.
