Abstract: An electrical connector includes a first female insert having pin engagable ockets and a second female insert having pin engagable sockets. The first insert is in electrical connection with the second insert. The socket inserts are connected via connector pins which are configured to fit within the sockets and between the socket members. The connector pins function to electrically connect the socket inserts and may include a locking extension for locking the pins in the sockets of the female inserts. The connector may also include a protective disk disposed between the socket inserts which envelopes the connector pins and protects them from damage.

Abstract: A single in-line fiber-optic rotary joint includes inner and outer concenc body portions which are rotatable relative to each other around a common longitudinal axis. An optical to electrical converter is mounted in the inner body portion and it is operative for receiving an incoming optical signal and converting it to a corresponding electrical signal. A light source mounted along the longitudinal axis of the inner body portion receives the converted electrical signal and emits a corresponding light signal along the longitudinal axis. A light detector is positioned along the longitudinal axis in the outer body portion wherein it receives the light signal and generates a corresponding electrical signal. The electrical signal from the light detector is received by an electrical to optical converter which converts the electrical signal back to an optical signal, thus establishing a complete pathway through the rotary joint.

Abstract: A flipper energy source for generating electricity includes a flipper or having an opening for engaging a foot and a body portion extending therefrom. The body portion includes fluid displacing surfaces which are adapted to be moved through the fluid for creating a propelling force via the movement. Such movement causes stress to be created on the surfaces of the body portion. The device further includes a piezoelectric element for converting the stress into electric power. The electric power thus generated is conditioned for use in powering electrical device(s), such as, for example, lighting, communications devices, battery rechargers, photography equipment and sonar transducers.
