Abstract: A device for retaining a bicycle chain on a sprocket includes a base plate defining a plurality of fastener openings centered on an origin. A center of each of the plurality of fastener openings is disposed at a first radial distance from the origin. The origin defines an axis extending substantially orthogonally from a plane defined by two lines extending from the origin and at least two centers of the centers of the plurality of fastener openings. A first guard is secured to the base plate and includes a first guard retaining surface including a first curved surface defined by a second radial distance from the axis that is greater than the first radial distance and a first guard guiding surface having a first end adjacent the first guard retaining surface and a second end distal from the first end. The first end is disposed at the second radial distance from the axis. The second end is disposed at a third radial distance from the axis. The third radial distance is greater than the second radial distance.

Abstract: A bicycle tail light or front light has a mounting base to connect to the bicycle, and an LED light unit for insertion into and removal from the base. The light unit includes a printed circuit board with LED driver and a rechargeable battery, all of which are encapsulated by a direct overmolding that forms a casing for the unit. For charging the light unit is pulled out from the base and plugged into a USB port. A tongue with USB blade at the back of the light unit functions to secure the light unit to the mounting base, and the attachment of the units switches power to the light unit. A motion detector on the PCB shuts off the LED if no motion is detected for several minutes, thus eliminating need for any exterior switch.

Abstract: A mounting system for a bicycle light, camera, bike computer, smartphone or other device has versatile application to front or rear of the bike, to fix the light or device in position at the desired orientation. The mounting system has a ball arm engaged by adjustable clamps, one on each of two ball ends of the ball arm, providing a wide range of adjustments to attach the light housing or device to different configurations of bicycle stems and to seat rails below the seat, accommodating a range of different spacings and angles.

Abstract: A method of installing a socket with a socket contact on an underwater plug with a plug contact is provided so as to establish conductive contact between the socket contact and the plug contact. The socket is disconnectably attached to a recoverable fluid exchange unit and the socket engages with the plug to establish the conductive contact between the socket contact and plug contact. The recoverable fluid exchange unit is then operated to substantially replace a first fluid within the socket with a second fluid from the recoverable fluid exchange unit.

Abstract: A valve actuator (1) is provided which comprises an actuator stem (4) extending from a housing (2) which contains a sleeve (17). The actuator stem (4) is driven so as to cause the sleeve to compress a stack of springs (22) within the housing until bolts (25) engage the sleeve, locking the springs in a compressed state. At the same time an armature (28) on the actuator stem is attracted to an electromagnet (29) within the housing. The actuator stem can then be driven to open or close a valve in a controlled manner without first compressing or releasing the springs. In an emergency, the electromagnet is switched off, releasing the armature thus unlocking the stack of springs. The released springs push the piston which partially retracts the actuator stem into the housing causing the valve to be closed.
