Abstract: Remotely controlled rescue systems and associated methods and kits are described. An example embodiment of a remotely controlled rescue system includes a vehicle, a storage container attached to the vehicle, a cord disposed within the storage container, a personal floatation device attached to the vehicle, and a controller. The vehicle includes a first motor, a support frame, a main body formed of a material that is buoyant in water, a second motor, and a bottom plate formed of a material that is buoyant in water. The first motor is attached to the support frame and produces ground propulsion. The second motor produces marine propulsion and is attached to the bottom plate. The cord has a first end attached to a portion of the remotely controlled rescue system.

Abstract: A remote throttle control device for snowmobiles includes a throttle coupler for releasable mounting to a snowmobile throttle controller. The throttle coupler mounts to a first end of a flexible push/pull cable. A manually operable remote actuator is mounted to an opposite second end of the push/pull cable. The remote actuator is for pushing or pulling the push/pull cable, so as to respectively push or pull the throttle coupler for actuation of the throttle controller when the throttle coupler is mounted to the throttle controller. The remote actuator is mounted to a pull handle. A strap is mountable at one end to the handle and at its opposite end to the ski of the snowmobile so that the ski may be pulled on by a user while the user simultaneously remotely controls the snowmobile throttle.

Abstract: A snowmobile includes a mountain strap for allowing a rider to shift his or her weight on the snowmobile to a greater degree in order to improve the handling characteristics of the snowmobile when traversing steep terrain or turning tightly at elevated speeds. The snowmobile includes a steering assembly and a handlebar connected to the steering assembly. The handlebar includes a central mounting portion, upright portions extending generally upwardly from each side of the central mounting portion, grip portions extending generally outwardly from the upright portions, and curved portions formed between the upright portions and grip portions. A mountain strap is provided comprising a core member having first and second ends which extend around the handlebar and are connected to the core member to form loop portions. The loop portions are positioned at the curved portions of the handlebar.

Abstract: A self-propelled ice rescue device component, as well as the device itself. The component includes (a) a main support frame; (b) a motor attached to the main support frame; (c) a power source connected to the motor for driving the motor; (d) a control mechanism attached to either the power source or the motor or both; (e) a flexible cord member having a first end and a second end, the first end being attached at least to the control mechanism said second end being remotely located from the main support frame so as to be freely useable by an operator; (f) a plurality of rotator members driveably connected to the motor; and, (g) a connector on the main support frame for attaching the self-propelled ice rescue device component to a floatable base platform. The device itself is one which encompasses the aforesaid component with a floatable base platform removably or permanently attached thereto. In one preferred embodiment the floatable base platform is a ladder with floatation devices thereon.

Abstract: An exhaust gas cleaning device of an internal combustion engine wherein a secondary-air supply passage is connected to an exhaust system of the engine and a reed valve means is provided in the intermediate part of the secondary-air supply passage for opening in response to the pulsation pressure of the exhaust gas in the exhaust system to supply secondary air for cleaning exhaust gas to an exhaust passage and burn the unburnt components present in the exhaust passage thereby to clean exhaust gas. A desired amount of secondary air is supplied to each of a plurality of exhaust systems so that the exhaust gas cleaning efficiency as well as the reliability and durability of the reed valve means are improved and moreover a good external appearance is obtained.
