  • Patent number: 11911658
    Abstract: Disclosed are various embodiments of a golf training system. In one non-limiting example, a system includes a feedback device, a sensor, and a computing device. The computing device is configured to at least receive sensor data from the sensor during the golf swing of the user and identify a plurality of body movements in which each respective body movement corresponds to a stage of a golf swing sequence based at least in part on the sensor data. The computing device can also be configured to activate a plurality of feedback indicators according to the golf swing sequence for feedback to the user during the golf swing.

  • Publication number: 20240049993
    Abstract: The present disclosure describes systems and methods to evaluate auditory efferent function by exposing a patient to short-duration acoustic click stimuli to generate a click-evoked otoacoustic emission (CEOAE) occurring in each ear of the patient, and in response to exposing the patient to click stimuli, concurrently sampling outer hair cell activity (OHC) and medial olivocochlear reflex (MOCR; efferents) in each ear of the patient, monitoring the middle ear muscle reflex (MEMR) in each ear of the patient, and measuring a change in cochlear activity in the patient based on the CEOAE, MOOR, and MEMR of each ear of the patient.

  • Patent number: 11612798
    Abstract: Disclosed are various embodiments of golf training device that helps a golfer learn and coordinate lower body positions and movements with upper body movements, using a series of feedback signals. In one embodiment, among others, a system comprises a foot sensor that attaches to a Lead Foot of a user. The foot sensor is configured to detect a heel of the Lead Foot being raised. The system also comprises a leg sensor that attaches to a Trail Leg of the user, and the leg sensor detects a bend in the Trail Leg of the user. The foot sensor is configured to detect the heel being lowered at an instance after the detection of the bend in the Trail Leg. The system further comprises a feedback device configured to activate one or more feedback indicators after the detections of foot and/or leg movements.

  • Publication number: 20200238149
    Abstract: Disclosed are various embodiments of golf training device that helps a golfer learn and coordinate lower body positions and movements with upper body movements, using a series of feedback signals. These signals force a lifted Lead Heel and bent Trail Knee starting at the beginning of the backswing and force the downswing to begin by replacing the Lead Heel while the Trail Knee is still bent. In one embodiment, among others, a system comprises a foot sensor that attaches to a Lead Foot of a user. The foot sensor is configured to detect a heel of the Lead Foot being raised. The system also comprises a leg sensor that attaches to a Trail Knee of the user, and the leg sensor detects a bend in a knee of a Trail Leg of the user after detecting the heel being raised. The foot sensor is configured to detect the heel being lowered at an instance after the detection of the bend in the knee of the Trail Leg and while the knee remains bent.

  • Patent number: 9867572
    Abstract: Methods and systems for rapidly determining and displaying the depth of ear tip placement to improve the reliability of hearing tests may comprise in a hearing assessment system comprising a control system and a probe with a sealing ear tip, a microphone, and a sound source: measuring a pressure versus frequency of an ear canal, determining a first half-wavelength frequency of the ear canal using the measured pressure versus frequency and/or or from the phase of the ear canal reflectance, and calculating a distance between the hearing probe and an eardrum in the ear canal based on the determined first half-wavelength frequency. Subsequent measurements of the ear canal may be performed using the calculated distance. The calculated distance may be stored in a memory in the control system for the subsequent measurements of the ear canal. The calculated distance may be displayed on a gauge on the control system.
