Abstract: A jumping toy and the methodology of creating a cascading arrangement of multiple jumping toys. Each jumping toy has a first segment and a second segment that are connected at a joint. The first segment and the second segment can rotate about the joint between a first configuration and a second configuration. Each jumping toy has a biasing element that biases the jumping toy toward its second configuration. Each jumping toy is stable in its first configuration and quickly transforms into its second configuration once it is slightly displaced out of its first configuration. The rapid change in configuration makes the bi-stable toy jump. A plurality of bi-stable toys can be overlapped into a cascading chain. The first toy in the cascading chain is triggered. The movement of the first toy triggers the next toy in the chain in a cascade.

Abstract: A bi-stable jumping toy that can be operated individually or with other jumping toys in a cascading chain. The toy has a first segment and a second segment that are joined in a scissor configuration. An elastic band extends between the first segment and the second segment. The elastic band biases the toy into the second configuration. However, the first segment and the second segment can be manually rotated into the stable first configuration. In the first configuration, the elastic band is stretched across the pivot axis and provides no rotational bias to either the first segment or the second segment. The toy is triggered by rotating the first segment and/or the second segment only slightly out of the first configuration. Once moved, the spring energy in the elastic band releases and the toy rapidly moves into its second configuration.

Abstract: A handheld grip assist device for use in gripping an object in a sanitary manner. The grip assist device has a clamshell construction, wherein two assemblies are joined at a hinge. The two assemblies have a rigid frame that support elastomeric panels. Movement between an open configuration and a closed configuration are controlled by engaging the grip assist device between a thumb and finger and using the muscles of the hand to open and close the grip assist device. In this manner, the grip assist device can be precisely controlled while preventing any direct contact between a gripped object and the skin of the hand. The grip assist device can be locked in its closed configuration, therein isolating surfaces on the grip assist device that could cause cross-contamination.
