System and method for detecting lower body positions, movements, and sequence in golf swing training
Patent number: 11612798Abstract: 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.Type: GrantFiled: November 2, 2021Date of Patent: March 28, 2023Assignee: PD Golf LLCInventors: James R.

SYSTEM AND METHOD FOR DETECTING LOWER BODY POSITIONS, MOVEMENTS, AND SEQUENCE IN GOLF SWING TRAINING
Publication number: 20200238149Abstract: 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.Type: ApplicationFiled: January 25, 2019Publication date: July 30, 2020Inventors: James R.

Patent number: 9867572Abstract: 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.Type: GrantFiled: September 10, 2014Date of Patent: January 16, 2018Assignee: ETYMOTIC RESEARCH, INC.Inventors: Mead Killion, Jonathan Siegel, Sumitrajit Dhar
