Abstract: A single-sprocket system for integration into a bicycle trainer, the system including a sprocket having teeth about a perimeter of the sprocket, a first planar side, and a second planar side, wherein the teeth of the sprocket are configured to engage a chain of a bicycle mounted to the bicycle trainer. The system further includes a first chain guide adjacent the first planar side of the sprocket, wherein the first chain guide is configured to re-engage the teeth of the sprocket with the chain when the chain has become disengaged from the teeth of the sprocket towards the first planar side, and a second chain guide adjacent the second planar side of the sprocket, wherein the second chain guide is configured to re-engage the teeth of the sprocket with the chain when the chain has become disengaged from the teeth of the sprocket towards the second planar side.

Abstract: An adapter apparatus for connecting a sensor device and a base device includes an RJ-45 connector pluggable into the base device. Among the RJ-45 contacts are a power supply contact and data contact for the base device as well as a ground contact. The adapter apparatus further includes an RJ-12 port capable of accepting an RJ-12 connector of the sensor device; among the RJ-12 contacts are a power supply contact and data contact for the sensor device as well as a ground contact. The adapter apparatus further includes a housing enclosing power supply, data, and ground wires for internally connecting the respective RJ-45 and RJ-12 power supply, data, and ground contacts.

Abstract: There is disclosed a chain tensioner system including a pulley for rotatably engaging a bicycle chain or belt, a pulley arm, upon which the pulley is mounted, the pulley arm movable between a closed position and an open position, a fixed tensioner arm, engaged with the pulley arm, and a tensioner element for connecting the fixed tensioner arm with the pulley arm, the tensioner element for keeping the pulley arm in either the closed position or the open position under tension provided by the tensioner element when the pulley arm is in either the closed position or the open position.

Abstract: There is disclosed an adjustable single-sprocket system including a sprocket having an opening for an axle, the sprocket having teeth about a perimeter of the sprocket, wherein the teeth of the sprocket are for engaging a bicycle chain, an adjustment dial, having an opening for the axle, the adjustment dial incorporating at least two adjustment ramps along a dial side closest to the sprocket, and a camming spacer, having an opening for the axle and including at least two camming ramps to engage with the at least two adjustment ramps to increase or decrease distance of the sprocket from the adjustment dial along a rotation axis about the sprocket as the adjustment dial is rotated about the rotation axis in a first direction or a second direction.

Abstract: A camera is disclosed comprising a substantially cylindrical camera body defining a longitudinal axis and a mounting system rotatably connected to the camera body, the mounting system comprising a base portion for mounting the camera to another object and at least one ring member arranged to surround the camera body and rotate around the longitudinal axis of the camera body during use.

Abstract: A digital video camera is disclosed comprising a substantially cylindrical camera body defining a longitudinal axis, and first and second user inputs arranged on a wall of the camera body, wherein one of the first and second user inputs is arranged on a side wall of the camera body in a plane that is generally parallel to the longitudinal axis, and the other of the first and second user inputs is arranged on an end wall of the camera body in a plane that is generally orthogonal to the longitudinal axis, one of the first and second user inputs being actuable to start recording and the other of the first and second user inputs being actuable to stop recording.

Abstract: A camera is disclosed comprising a mounting system including a base portion for mounting the camera to another object, wherein the base portion comprises a pair of levers arranged on top of one another to pivot in-plane to enable connection or disconnection of a mounting interface to the mounting system.

Abstract: A removable power pack for a camera is disclosed comprising a battery module and a data storage module housed in a common casing to form an integrated unit, wherein the casing exposes one or more electrical connectors for transmitting power and data between the power pack and a camera that receives the power pack. A waterproof camera is also disclosed comprising a camera body and a removable power pack installed in or on the body, the removable power pack including one or more electrical connectors for transmitting power to the camera once installed, and a sealing interface arranged between the camera and the power pack to prevent moisture from reaching the one or more electrical connectors.

Abstract: A lift mechanism includes a balance structure configured to hold an object, wherein the balance structure is rotateably connected to an arm structure at a pivot point. The pivot point is configured, and the object is positioned, such that the pivot point is substantially coincident with the center-of-mass of the object being moved. Weights may be selectively attached to the balance structure to adjust the center-of-mass. In one embodiment, the lift mechanism includes a base and an arm configured to rotate with respect to the base, wherein the arm is attached to the balance structure at the pivot point. In this way, heavy objects may be lifted, translated, and rotated into place safely in an efficient manner.
