Abstract: Disclosed is a golf ball retrieval device configured for retrofit to a putter grip. An exemplary embodiment generally takes the form of a cylinder having an interior space defined on one end, i.e. the golf ball receiving end, by a front diameter large enough to receive a golf ball and, on the opposite end of the interior space, i.e. the golf ball retention end, a rear diameter small enough to prevent a received golf ball from passing through. In some embodiments, the interior surface slopes from the front diameter back to the rear diameter. As such, one of ordinary skill in the art will recognize that the interior surface of some embodiments operates to substantially define a space in the shape of a frustum. Advantageously, embodiments of a golf ball retrieval device receive, retain, and release a golf ball by leveraging only gravitational forces.

Abstract: A basketball net may be constructed from fabric. Appropriate fabrics may include knit fabrics made from durable materials, such as nylon thread. Monofilament nylon in a knit fabric having perforations manufactured in the fabric, may provide resilient nets capable of stretching in two dimensions. Nets may be constructed in a shape resembling a frustum of a cone. The frustum may be constructed from multiple pieces. Fabric may be laid flat, and cut in tapered pieces, having the fabric oriented in a direction selected to provide the best performance in service. Segments may be hemmed together along more-or-less vertical lines on the edges of the frustum. The net is manufactured of a fabric selected to provide a substantial fraction of its overall area in a surface for receiving an image. However, a substantial portion of the overall area of the fabric of the net may be voids for providing resilient stretching and service.
