Abstract: A bicycle with one or more brake lights, brake levers configured to activate integral pressure switches upon depression wherein said integral pressure switches are configured to trigger a BLE transmitter to send a BLE signal to one or more BLE receivers in communication with the one or more brake lights thereby actuating the same. The brake light can be mounted on the bicycle seat or seat post or can be integrated into a helmet design or retrofitted to an existing helmet. The bicycle system includes turn signals actuated using BLE signals. A mobile device may be incorporated into the system to utilize BLE signals to wirelessly control gear shifting of the bicycle responsive to a rider's physical condition (e.g., heart rate) in combination with bicycle conditions (e.g., crank torque) and environmental conditions (e.g., wind speed and direction).

Abstract: A tactical rail incorporating integral conductive elements positioned in rail channels or grooves wherein the conductive elements are powered by a single battery. Accessory mounts incorporate conductive elements positioned to contact the conductive elements in the rail grooves thus receiving electric current from the conductive elements and delivering the same to the connected accessories. A rubber O-ring strip or gasket may be removably positioned over the conductive elements positioned in the rail grooves thereby preventing the system from shorting out and protecting the conductive elements from external conditions, including moisture. When needed, portions of the O-ring strip may be cut-away to accommodate the conductive elements of one or more accessory mounts.
