Abstract: A force or pressure transducer is includes a substrate, a dielectric material disposed on the substrate, a spacing member disposed on the dielectric material, and a resilient element disposed on both the dielectric material and the spacing member. A portion of the resilient element is separated from the dielectric material, and another portion of the resilient element is in contact with the dielectric material. The contact area between the resilient element and the dielectric material varies in response to movement of the resilient element. Changes in the contact area alter the capacitance of the transducer, which can be measured through associated circuitry.

Abstract: A method and apparatus for training a user to move in a desired movement pattern, especially for training a golfer to swing a golf club. One or more sensors are placed adjacent the user, for example pressure sensors under the user's feet and/or between the user's hands and a golf club. The sensors generate signals corresponding to the user's movement. A comparator and signal generator are used to compare a function of the user signals and a reference value, and to generate training signals which are communicated to the user, e.g. by radio frequency signals received by a headset worn by the user. In this way, the user senses, during the actual movement, training signals which represent a relationship between the actual movement pattern and a desired movement pattern.

Abstract: A sports training aid has a pair of foot sensors, insertable in a pair of shoes, which generate measurement signals indicative of weight applied to each of the foot sensors. The training aid compares the measurement signals with a specified range of values and produces audible sounds indicative of the relationship between those measurement signals and the specified range of values, thereby providing the training aid's user with immediate audible feedback regarding weight shifts. A grip sensing version of the sports training aid uses a grip pressure sensor which generates a measurement signal indicative of grip pressure applied to the handle of a swingable object, such as a golf club or baseball bat. When the user's grip pressure falls outside specified threshold values, audible tones are generated. In both versions, the user receives the audible feedback signals via a headset worn while using the sports training aid.
