1. A safety system for an elevator, comprising:
slip detection means for detecting a slip between a drive sheave and a main rope;
a safety gear mounted to a car, the safety gear being electrically operated by an actuator to cause the car to make an emergency stop regardless of whether a running direction of the car is upward or downward; and
a safety gear controller for cutting power supply to a hoisting machine motor and causing the safety gear to make a braking operation upon detection of the slip between the drive sheave and the main rope by the slip detection means,
wherein the slip detection means comprises a slip detection circuit for judging occurrence of the slip between the drive sheave and the main rope when a rate of reduction of a motor torque of the hoisting machine motor becomes larger than a predetermined value during normal running of the car.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1-10. (canceled)
11. A combination sensor module for a vehicle, comprising:
at least two sensor submodules disposed in the combination sensor module and able to be connected to an electronics system of the vehicle, the at least two sensor submodules being able to be operated independently of each other.
12. The combination sensor module as recited in claim 11, wherein the at least two sensor modules are able to be operated independently so that one of the at least two sensor submodules is set up to continue operating in case of a defect or a malfunction of the other one of the at least two sensor submodules.
13. The combination sensor module as recited in claim 11, further comprising:
an interface module, the at least two sensor submodules coupled to the interface module for communication purposes, and the interface module to provide at least one of the functions from the group consisting of: energy supply, diagnosis, signal conditioning and interface functionality for the at least two sensor submodules.
14. The combination sensor module as recited in claim 11, wherein at least one of: i) each of the at least two sensor submodules is developed as a 3D sensor module, and ii) the at least two sensor submodules are jointly developed as a 6D sensor submodule.
15. The combination sensor module as recited in claim 11, wherein each of the at least two sensor submodules is developed as a sensor module from the group consisting of:
rollover sensor module, pitch rate sensor module, ESP sensor module, 3D rate-of-rotation module, and triaxial acceleration sensor.
16. The combination sensor module as recited in claim 11, wherein the at least two sensor submodules are developed to be galvanically separate of each other, and disposed in the combination sensor module.
17. The combination sensor module as recited in claim 11, wherein the combination sensor module is configured so that it is operable as a 6D sensor module when the at least two sensor submodules do not have any defect, and the combination sensor module is operable at least as a 3D sensor module if one of the at least two sensor submodules has a defect.
18. An automobile, including a combination sensor module, the combination sensor module including at least two sensor submodules disposed in the combination sensor module and able to be connected to an electronics system of the vehicle, the at least two sensor submodules being able to be operated independently of each other.
19. A method, comprising:
providing a combination sensor module in a vehicle, the combination sensor including at least two sensor submodules disposed in the combination sensor module and able to be connected to an electronics system of the vehicle, the at least two sensor submodules being able to be operated independently of each other; and
using the combination sensor.
20. The method as recited in claim 19, wherein the using step includes operating the combination sensor module as 6D sensor module when the at least two sensor submodules do not have any defects, and operating the combination sensor module at least as a 3D sensor module when one of the at least two sensor submodules has a defect.
