Abstract: In an embodiment, the invention provides an apparatus for comprehensive vision and audio screening, the apparatus including a housing having left and right separated compartments. Each of the left and right separated compartments contains a distance- and contrast-adjustable component of a stereo display that can be switched to be transparent with a rear display providing background and see-through capability, a semitransparent mirror, a lens with built-in camera, an LED module, a light source with a set of filters, a light module, and a component of a stereo speaker. The apparatus further includes a communication module, an accelerometer, a three-axis gyroscope, a light detector, a processor; a memory storing firmware, and a power supply component having a rechargeable battery and a charging component.

Abstract: Disclosed is an apparatus for therapy of cognitive impairment. In an embodiment, the apparatus includes a headwear cognition therapy unit comprising a housing having a display, a camera, a microphone, a speaker, a communication module configured to exchange data with an external service unit, an accelerometer, a three-axis gyroscope, and a memory storing data comprising firmware. The firmware is configured to use the speaker and the display to implement cognitive therapy and to detect when a patient is moving and switch the unit from VR mode to AR mode or transparent mode such that the patient can see his/her surroundings.

Abstract: A system for comprehensive multisensory vision, hearing, and cognitive screening includes a headwear test unit comprising a configurable video, audio, and hand-gesture capable testing device. The system further includes an identification, anonymization and security module, a patient interface, an operator interface, a communication module, and a unit charging and calibration module and/or station. An adaptive real-time compiler compiles sequences of optometric hearing and cognition tests. A cloud-based web service module is configured for storing encrypted personal optometric information. A machine learning module is operatively connected to the cloud-based web service module.

Abstract: A vibration detector suitable for field use and associated systems and methods are disclosed. A representative apparatus includes a vibration sensor in contact with the vibrating structure. The vibration sensor can be in contact with the vibration isolators to eliminate the frequencies of the operator's hand. In some embodiments, a contact force between the vibration sensor and the vibrating structure can be measured using, for example, contact resistors. Since the sensitivity of the vibration sensor can be a function of the contact force, the vibration amplitude measurements can be adjusted for a known contact force to improve the precision of the vibration amplitude measurement.

Abstract: A system and method for analyzing a device that includes a mass configured for motion. The system includes a tri-axial accelerometer disposed to detect acceleration vectors of the device and to output three channels of acceleration data, and a user interface receiving the three channels of acceleration data. The user interface is configured to correlate the three channels of acceleration data with a reference frame defined by three orthogonal axes intersecting at a vertex, and includes a display and a selector. The display shows sets of options that represent dispositions of the device with respect to gravity, placements of the tri-axial accelerometer with respect to the device, and orientations of the tri-axial accelerometer with respect to the device. The selector selects one device disposition option, one tri-axial accelerometer placement option, and one tri-axial accelerometer orientation option.
