Abstract: A portable hearing screening and amplification device structured to be coupled to a headset includes: a housing, a plurality of buttons, a plurality of indicators, a microphone circuit, an output circuit, a power source, and a controller. Upon passing a background noise test, the portable hearing screening and amplification device is structured to transmit a plurality of hearing screening tones to the headset for a user for testing of the plurality of hearing screening tones and complete the hearing screening based on responses of the user related to the plurality of hearing screening tones, the responses including a number of hearing screening tones that the user has perceived during the hearing screening. Based on a determination that the number of hearing screening tones perceived is less than a prerequisite number, the portable hearing screening and amplification device is further structured to switch to amplification mode and provide amplification.

Abstract: A device for simultaneously monitoring the health of surgical drills and detecting proximity to critical structures during surgery is described herein. By using various sensors (e.g. microphones, accelerometers, temperature sensors, etc.), signals from the drill can be measured and analyzed. The processed signals can then be used to indicate the proximity of the drill bit to critical structures, such as the patient's brain, and identify drill health issues (e.g. worn bearings, misaligned rotational axis, etc.).
