A rollover sensing system (12) that may be used in the determination of when to deploy restraints in a vehicle is disclosed herein. The rollover sensing system (12) may include lateral acceleration sensors (22), a roll rate sensor (18), and a roll angle detector (20). A control circuit (16) determines a roll moment of inertia as a function of lateral acceleration, a trip point length as a function of the lateral acceleration, and a trip point angle as a function of the lateral acceleration. The control circuit (16) also determines a rollover threshold in response to a roll rate signal, a roll angle signal, the trip point length, the roll moment of inertia, and the trip point angle. The control circuit (16) further generates a control signal for a deployment circuit in response to the rollover threshold.

A vehicle light emitting display device is provided with at least one light source which can be controlled to turn on and off and a light reflecting member disposed in front of a driver of a vehicle. The vehicle light emitting display device forms a virtual image which can be observed by the driver, by emitting light of the light source from lower side of an instrument panel of the vehicle toward the light reflecting member. The vehicle light emitting display device is further provided with a forward and rearward movable mechanism that freely moves a position, at which light is emitted from the light source toward the light reflecting member, in a forward and rearward direction which is a travel direction of the vehicle.

The invention discloses an operating platform and relates to the technical field of wind power generation. The operating platform aims at solving the problems that an existing operating platform is high in manufacturing cost and low in production efficiency and influences layout of components in a tower frame. The operating platform is detachably connected with a lifting lug embedded in a concrete shell ring inner wall. The operating platform comprises a first platform box and a plurality of first platforms, a side wall of the first platform box is provided with first openings for the first platforms to penetrate, and lengths of the first platforms extending out of the first platform box are adjustable.

Described herein is a sprocket for interfacing with a perforated material, such as a chain. The sprocket includes a hub and a material-interfacing plate. The hub is shaped to fit around an axially extending shaft, and includes a plurality of hub portions each shaped to fit around a portion of the shaft; and a retaining portion and a hub interlocking portion, each disposed on at least one of the hub portions. The material-interfacing plate has a periphery that is shaped to interface with the perforated material, and includes a plurality of plate portions each shaped to fit around a portion of the hub; and a plate interlocking portion shaped to interlock with the hub interlocking portion and disposed on at least one of the plate portions. The material-interfacing plate is in a secured position when the plate interlocking portion and the hub interlocking portion are interlocked with each other. The interlocked plate and hub interlocking portions prevent the material-interfacing plate from sliding radially off the hub and the retaining portion prevents the material-interfacing plate from sliding axially off the hub when the material-interfacing plate is in the secured position.

A structural analysis apparatus automatically sets a boundary between an entire model and a detailed model to thereby obtain a highly accurate solution without intervention by an operator and with fewer man-hours and shorter calculation time. An iso-surface creation step creates a field iso-surface from an analysis result of a mesh model. A detailed mesh model creation step uses the field iso-surface created by the iso-surface creation step to create a detailed mesh model of a part of the mesh model. An analysis step uses the analysis result of the mesh model to perform analysis of the detailed mesh model created by the detailed mesh model creation step. An analysis evaluation step evaluates the analysis result of the detailed mesh model based on the analysis result obtained by the analysis step and analysis result of the mesh model.

The invention discloses a double-layer film bag device applied to injection pipe sealing in a water bursting sand layer. The device comprises an injection screen pipe; the front part of the injection screen pipe is provided with a conical piercing end; opposite outer side faces of the back half part of the injection screen pipe are respectively provided with an iron pipe and a rubber pipe; one end of an inner-layer film bag is fastened to the outsides of the iron pipe and the injection screen pipe; the outlet of the iron pipe is formed in the inner side of the inner-layer film bag and in the outer side of the injection screen pipe; one end of an outer-layer film bag is fastened to the rubber pipe and the injection screen pipe; the outlet of the rubber pipe is arranged in the inner side of the outer-layer film bag and in the outer side of the inner-layer film bag; the other ends of the inner-layer film bag and the outer-layer film bag are fastened to the injection screen pipe; a first grout blocking layer is formed between the inner-layer film bag and the injection screen pipe; a second grout blocking layer is formed between the outer-layer film bag and the inner-layer film bag. The invention also discloses a method for implementing the device. According to the device and the method, the problem of injection pipe sealing in the water bursting sand layer is researched, and problems that sealing slurry is easy to scatter under the moving water condition, a single-layer film bag is easy to damage and the injection screen pipe cannot reach design depth are solved.

A vehicle door sash structure includes a holding unit. The holding unit includes a guide locking portion arranged in a region of a run channel opposed in a vehicle inner-outer direction to a tip end rim of an inner beam portion in a state of temporary attachment after completion of attachment of a molding to an outer beam portion. The guide locking portion is inclined in a direction to guide the run channel to a position of completion of attachment while coming into contact with the tip end rim of the inner beam portion by an input of an attachment force in a direction to attach the molding to the run channel in the state of temporary attachment.

The invention discloses a construction method for a station side wall by a covered top-down excavation method, comprising the following steps of: using at least two movable type formworking jumbos and a Wisa panel of which two sides can be used for at least 80 times in an inverted way according to the height of the station side wall, and meeting the construction requirement by load-carrying checking computations; installing the formworking jumbos in site: assembling the formworking jumbos, walking the formworking jumbos, and adjusting the formworking jumbos in site; and casting a wall body, etc. The construction method has the beneficial effects of being simple in technology, high in operability, less in working hour consumption, high in material use ratio, good in apparent quality, and obvious in waterproofness; and the problem of the conventional technology for constructing the station side wall such as long working hour consumption, low material use ratio, bad apparent quality, more serious water leakage phenomenon, and the like can be solved.

The invention provides a Gaussian N75 printable wide and narrow newspaper transformation method. Through the steps of triangular plate cutting, base platform hole expansion, moving quantity modification and main paper leading roller group transformation, the narrow-width newspaper printing requirements with great dimension differences can be further met on the basis of maintaining the original wide-width newspaper printing, in addition, the cost of the transformation method is low, and in addition, the wasted work hours are few. In addition, the invention simultaneously provides a printable wide and narrow newspaper double-width rotary press, which is different from ordinary products, through adopting a novel triangular plate structure, a main paper leading roller structure, a transmission structure and a design of sufficient triangular plate horizontal moving quantity, the fast regulation can be realized, so the narrow-width newspaper printing requirements with great dimension differences can be met.
