Abstract: System and methods are provided for empirical analysis of remaining life in electromechanical devices. Sensors are positioned to generate signals representing sound energy emitted by devices, and digital sound data are stored corresponding thereto. The system classifies sound characteristics and their corresponding impact on wear rate over time via recurring analysis of the stored sound data. For a selected device, a wear state is estimated based on a comparison of current sound energy emitted therefrom with respect to sound data for a comparable group of electromechanical devices, and it may be ascertained whether certain classified sound characteristics are present in digital sound data corresponding to the selected electromechanical device. Output signals are selectively generated based on the estimated wear state and/or classified sound characteristics ascertained to be present, e.g.

Abstract: A system for percutaneous photobiomodulation (PBM) that can deliver light that is configured outside the body directly to target tissue is described. The system can be used to treat both chronic and temporary conditions with PBM. The system includes a light source and a controller that includes a memory storing a predefined dosing requirement and a processor to access the memory and signal the light source to generate a light signal for PBM of a target area within a patients body based on the predefined dosing requirement. In some instances, the system also includes a port to deliver the light signal received from the light source to the target area. The light source and the port can be connected by an attachment that can transmit the light signal from the light source to the port.

Abstract: Prioritizing a customer service agent's responses to customer messages. In one form, an expected response time target is determined based on a time interval between sending an agent response and receiving a customer response from a particular customer. In other forms, other objective factors, such as message intervals, customer properties, and message properties, are used to determine the expected response time target. In yet other forms, a customer conversation can be automatically closed if the customer does not respond within a predetermined maximum time interval.
