Abstract: Identifying a damaged tool, including capturing, by an optical scanner, images of a manufactured part machined by the damaged tool; determining, from the captured images by a data processor operatively coupled to the scanner, measurements of the part; and determining, by the data processor based upon the measurements, that the tool is damaged.

Abstract: An in-ear device with one or more proprioceptive features for providing an indication to a subject to help manage or reduce pain, discomfort, or other symptoms associated with TMJ disorder. In some embodiments, the one or more proprioceptive features are active and/or passive indicators. Also disclosed are methods of using optical scanning to create a three dimensional replication of the ear canal that is used to design a customized in-ear device.

Abstract: An in-ear device with at least one sensor configured to generate a signal to help a subject manage or reduce pain, discomfort, or other symptoms associated with TMJ disorder. Also disclosed are methods of using optical scanning to create a three dimensional replication of the ear canal that is used to design a customized in-ear device.

Abstract: An in-ear device with one or more proprioceptive features for providing an indication to a subject to help manage or reduce pain, discomfort, or other symptoms associated with TMJ disorder. Also disclosed are methods of using optical scanning to create a three dimensional replication of the ear canal that is used to design a customized in-ear device. In some embodiments, the in-ear device is customized based on the configuration of the subject's ear canal when the subject's jaw is in the therapeutic or optimal position.

Abstract: An in-ear device configured to help a subject manage or reduce pain, discomfort, or other symptoms associated with TMJ disorder. Also disclosed are methods of using optical scanning to create a three dimensional replication of the ear canal that is used to design a customized in-ear device. Also disclosed is a method of helping manage at least one symptom associated with TMD by customizing a series of in-ear device and modifying the devices over time, where each device in the series is customized to the subject.

Abstract: An in-ear device configured to help a subject manage or reduce pain, discomfort, or other symptoms associated with TMJ disorder. Also disclosed are methods of using optical scanning to create a three dimensional replication of the ear canal that is used to design a customized in-ear device. Also disclosed is a method of helping manage at least one symptom associated with TMD by providing an in-ear device for wear while the subject is awake and providing a bite guard for wear at night while the subject is sleeping.

Abstract: An in-ear orthotic with one or more features to help manage or reduce pain, discomfort, or other symptoms associated with temporomandibular joint disorder. Also disclosed are methods of using optical scanning to create a three dimensional replication of the ear canal that is used to design a customized in-ear orthotic to help manage one or more symptoms of temporomandibular joint disorder.

Abstract: Optical scanning with an optical probe composed of an elongated cylinder of transparent material mounted upon an optical scanner body; one or more sources of scan illumination mounted in the probe distally or proximally with respect to the scanner body and projecting scan illumination longitudinally through the probe; a radially-reflecting optical element mounted in the probe having a conical mirror on a surface of the radially-reflecting optical element, the mirror oriented so as to project scan illumination radially away from a longitudinal axis of the probe with at least some of the scan illumination projected onto a scanned object; a lens mounted in the probe between the radially-reflecting optical element and the scanner body and disposed so as to conduct to an optical sensor scan illumination reflected from the scanned object.

Abstract: An otoscanner including a conical laser-reflective optical element and a laser light source and the conical laser-reflecting optical element are configured so that the conical laser-reflecting optical element, when illuminated by the laser light source, projects a broken ring of laser light upon an interior surface of the ear when the ear probe is positioned in the ear and a diffractive laser optic lens and the laser light source and the diffractive laser optic lens are configured so that the diffractive laser optic lens, when illuminated by the laser light source, projects upon an interior surface of the ear a fan of laser light at a predetermined angle with respect to a front surface of the diffractive laser optic lens when the ear probe is positioned in the ear.
