The elevator has a car movable vertically within a shaft between lower and upper end positions and a drive system coupled to a traction system for controlling movement of the car. A limit switch which is open when the car is in a selected distance range from one of the end positions. The limit switch forms part of a power line supplying power to the drive system for controlling movement of the car in a direction towards that end position in an inspection operation. Thus movement of the car is prevented only in that direction when the car is in the selected distance range in an inspection operation.

The invention relates to a household cooking appliance which includes a receptacle (2). The inside of the receptacle (2) is provided with a cutting tool (4) which is driven by a motor (15). The receptacle (2) is closed by a removable cover (3) comprising a bracket (34) acting on a safety part (7) when the bracket (34) of the cover (3) is turned toward an operating position. The safety part (7) moves between an idle position and an activated position. The safety part (7) is returned to the idle position via a return mechanism (72). When the bracket (34) is on the operating position (34), the safety part (7) is brought t to the activated position. The safety part (7) comprises a metal braking shoe (76) rubbing against a transmission belt (16) rotatingly integrated to the cutting tool (4) when the safety part is in a rest position. The shoe (76) is arranged apart from the belt (16) when the safety part is in an activated position.

The invention discloses a method and system for establishing a security system based on a domain mechanism. The method includes the following steps of configuring domain management information, setting related information of a resource object, configuring and registering a failure diagnosis routine, starting the failure diagnosis routine, establishing a domain environment, initializing a securitycore, executing scheduling and running software, intersecting a software calling security API of a security domain with the security core, intersecting a software calling ordinary API of an ordinary domain with the security core, and regularly detecting the current system state through the security core. The system comprises system domains and application domains. The application domains include the security domain and the ordinary domain. The smaller the domain value of software is, the higher the authority is; software with high authority can have access to the software itself and resourceswith lower authorities, and software with the same authority can have access to one another. The domain mechanism is sufficiently used, and security isolation is achieved; the individualized securitysystem of different grades can be established; control is flexible, and strength is reasonable; hardware characteristics are not depended on, and portability is high.

The invention provides a method for creating a secret key as interconnecting a GERAN with an enhanced UTRAN. The method comprises the following steps of: obtaining a safety related parameter to an enhanced SGSN of the enhanced UTRAN service from the GERAN when a user device is moved to the enhanced UTRAN from the GERAN, generating an empty secret key of the enhanced UTRAN according to the safety related parameter, and/or generating the empty secret key of the GERAN for the enhanced SGSN of the enhanced UTRAN service and sending to the GERAN when the user device is moved to the GERAN from the enhanced UTRAN. The invention provides a system for creating a secret key as interconnecting GERAN with enhanced UTRAN.

The invention provides a fault detector which is used for detecting modification of internal data of an intelligent card by various external attacks in application of high safety performance intelligent cards and stimulating corresponding protection measures to ensure that the intelligent card works in the safe and reliable state.

The invention relates to the technical field of escalators, in particular to a safety system structure of an escalator. The safety system structure comprises an upper engine room control board and a lower engine room control board, wherein the upper engine room control board is arranged in an upper engine room, and the lower engine room control board is arranged in a lower engine room. A first chip electrically connected with the upper engine room control board is mounted on the upper engine room control board, a second chip electrically connected with the lower engine room control board is mounted on the lower engine room control board of the lower engine room, and the first chip is electrically connected with the second chip through a safety bus. The safety system structure is high in safety, less in wire consumption, low in cost and more stable.

The invention discloses an oil drum transportation vehicle for mechanical part machining. The oil drum transportation vehicle comprises a weighing bracket, a hydraulic telescopic machine, a cylinder holding ring connecting frame, a protecting hook telescopic module, a reversing speed reducer, a support frame and a control mechanism; the two sides of the weighing bracket in the width direction arein buckling connection with one end of the cylinder holding ring connecting frame through fixed blocks; the protecting hook telescopic module is in locking connection to the surface of the other end of the cylinder holding ring connecting frame; the control mechanism is connected to the surface of one side of the weighing bracket by screws; the support frame is welded at the bottom end of the weighing bracket; movable wheels are fixedly connected to the bottom end surface of the support frame; weighing rollers are connected to the bottom end surface of the weighing bracket through rolling shafts; the cylinder holding ring connecting frame comprises a cylinder holding ring frame, a cylinder holding ring and a locking rope; one end of the cylinder holding ring frame is movably connected to the internal surface of the weighing bracket; and the other end of the cylinder holding ring frame is movably connected with the reversing speed reducer through a rotating shaft.

The invention discloses a water tank garbage disposer. The water tank garbage disposer comprises a tank body, a water inlet device, a crushing knife and a drainage pipe. The crushing knife is arrangedin the tank body and comprises blades and a motor; the tank body is integrally connected or closely connected with the water tank; the path of the drainage pipe is provided with an electric control drainage valve; and a partition plate is arranged between the crushing knife and the drainage pipe, the partition plate faces the radial direction of the crushing knife, and the partition plate is provided with filter holes. The water tank garbage disposer further comprises a central control circuit board, and the motor, the electric control drainage valve and the water inlet device are connected with the central control circuit board. By means of the garbage disposer independent of the water tank, the water tank and the garbage disposer can work at the same time, solid garbage generated by thewater tank can be disposed in time, the garbage disposal efficiency is improved, the electric control drainage valve enables the garbage disposer to independently store water, the water consumption is reduced, and the sanitary quality in the garbage disposal process is improved. The garbage crushing effect is further improved by arranging the partition plate and the filter holes formed in the partition plate.
