1. A seat belt system comprising:
a seat belt;
a retractor capable of retracting the seat belt; and
a controller operably coupled with the retractor to control movement of the seat belt, wherein the controller is configured
(a) to receive a command to enter a stop mode;
(b) to switch off a first set of components of the controller to enter a low power mode of operation;
(c) after expiration of a first time period, to switch on a first component of the first set of components to check for expiration of a second time period;
(d) to monitor for movement of the seat belt;
(e) if no belt movement is detected, repeating (b)-(d) until expiration of the second time period; and
(f) if no belt movement is detected before expiration of the second time period, to switch off the first set of components of the controller to enter a sleep mode of operation.
2. A method of transitioning a seat belt controller to a sleep mode, the method comprising:
(a) receiving a command to enter a stop mode;
(b) switching off a first set of components of the seat belt controller to enter a low power mode of operation;
(c) after expiration of a first time period, switching on a first component of the first set of components to check for expiration of a second time period;
(d) monitoring for movement of a seat belt;
(e) if no belt movement is detected, repeating (b)-(d) until expiration of the second time period; and
(f) if no belt movement is detected before expiration of the second time period, switching off the first set of components of the seat belt controller to enter a sleep mode of operation.
3. The method of claim 2, wherein (c)-(d) further comprise, after expiration of the first time period, switching on the first set of components of the seat belt controller and monitoring for movement of the belt monitor during a third time period, wherein (b)-(d) is repeated after expiration of the third time period without detection of belt movement.
4. The method of claim 2, wherein the second time period is approximately ten minutes.
5. The method of claim 2, wherein the first time period is less than approximately 350 milliseconds.
6. The method of claim 2, further comprising, if belt movement is detected before expiration of the second time period, switching on the first set of components of the seat belt controller to enter a full awake mode of operation.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A brake device for a motorcycle with a swing arm and an axle, comprising:
a worm wheel that meshes with the axle;
the worm wheel for meshing with a worm gear of a propeller shaft that transmits a rotational output outputted from an engine of the motorcycle;
a brake caliper for braking;
a brake caliper for parking;
a gear case cover that covers the worm wheel;
said brake caliper for braking supported on said gear case cover; and
said brake caliper for parking supported on said gear case cover;
wherein the brake caliper for braking and the brake caliper for parking are arranged separately above and below the swing arm of the motorcycle;
wherein the brake caliper for braking and the brake caliper for parking are arranged separately entirely above and entirely below the axle; and
further wherein, both the brake caliper for braking and the brake caliper for parking are arranged in front of the axle and not behind the axle.
2. The brake device according to claim 1, wherein the brake caliper for parking is a mechanical brake caliper.
3. The brake device according to claim 1, wherein the brake caliper for parking is arranged below the swing arm of the motorcycle.
4. The brake device according to claim 3, wherein the brake caliper for parking is miniaturized compared to the brake caliper for braking.
5. A brake device for a motorcycle with a swing arm and an axle, comprising:
a worm wheel that meshes with the axle;
the worm wheel for meshing with a worm gear of a propeller shaft that transmits a rotational output outputted from an engine of the motorcycle;
a brake caliper for braking;
a brake caliper for parking;
a gear case cover that covers the worm wheel; and
first and second mounting brackets integrally formed on said gear case cover, said first and second mounting brackets being forward of said axle, said first mounting bracket being above said swing arm and said second bracket being below said swing arm, said brake caliper for braking being mounted on said first mounting bracket and said brake caliper for parking being mounted on said second bracket;
wherein the brake caliper for braking and the brake caliper for parking are arranged separately above and below the swing arm of the motorcycle; and
further wherein, both the brake caliper for braking and the brake caliper for parking are arranged in front of the axle and not behind the axle.
6. The brake device according to claim 5, including said motorcycle.
