Abstract: A health monitoring system for an electrically-conductive tension member of an elevator system belt includes a transmitter including a transmitter coil configured for placement at the tension member, a receiver configured to be positioned at the tension member, and a controller operably connected to the transmitter and the receiver. The controller is configured to direct an alternating current through the transmitter coil resulting in the generation of a magnetic field and eddy currents at the transmitter coil, evaluate fluctuations in the magnetic field detected at the receiver. The fluctuations are indicative of wear or damage to the tension member.

Abstract: A sheave knurling tool is adapted to knurl a sheave while carrying a belt and coupled to a drive unit for rotation. The sheave knurling tool may include a body, an arm, a jack, and a knurling wheel. The body is detachably coupled to a support structure of the drive unit. The arm is pivotally engaged to the body about a pivot axis. The jack is adjustably coupled to, and extends between, the body and the arm. The knurling wheel is carried by the arm, and the jack is constructed and arranged to pivot the arm toward the sheave thereby exerting a biasing force of the knurling wheel against the sheave.

Abstract: The present disclosure relates generally to fusion proteins including gigaxonin coupled to a cell penetrant peptide. These fusion proteins can be used to treat GAN in a subject in need thereof. Administration of the fusion proteins allows for control of at least one of Galectin-1 (GAL-1) levels and phosphorylated vimentin protein levels, thereby mediating aggregation of vimentin and the formation of vimentin-free zones in cells.
