Abstract: A portable training device to be used by one practicing the game of tennis or golf. The training device includes a stand to rest on a flat surface, an adjustable hoop through which a tennis ball or a golf ball is hit, and a hoop support extending between the stand and the hoop. The adjustable hoop is rotatable between a vertical position, standing upwardly from and in axial alignment with the hoop support, and a horizontal position, facing the flat surface in perpendicular alignment with the hoop support. The length of the hoop support is adjustable so that the distance between the hoop and the stand can be correspondingly adjusted to meet the needs of the user.

Abstract: A portable training device to be used during sports and non-sports related practice activities. The training device includes a stand to rest on a surface, an adjustable hoop through which an object is moved during practice, and a hoop support extending between the stand and the hoop. In one embodiment, the adjustable hoop is rotatable between a vertical position, standing upwardly from and in axial alignment with the hoop support, and a horizontal position, facing the flat surface in perpendicular alignment with the hoop support. The length of the hoop support is adjustable so that the distance between the hoop and the stand can be correspondingly adjusted to meet the needs of the user.

Abstract: A record/playback module includes a case and an electronic circuit supported by the case for recording an audio message under control of a user and thereafter automatically playing the audio message in response to a change in ambient light. The electronic circuit has a RECORD mode of operation in which the electronic circuit records the audio message and a PLAY mode of operation in which the electronic circuit plays the audio message. The electronic circuit includes a first switch for initiating the RECORD mode of operation and a light sensitive subcircuit for initiating the PLAY mode of operation. The light sensing subcircuit is adapted to initiate the PLAY mode of operation when a second switch is in a first switch position and the ambient light increases, and when the second switch is in a second switch position and the ambient light decreases.
