摘要:
An occupant weight sensor (1) for placement between a frame (7) fixed to the chassis of a vehicle and a second frame (8) supporting a vehicle seat has a sense element having a first body (12, 22, 28, 34, 50, 62, 64, 68) formed with a planar sense surface on which are mounted piezoresistors electrically connected in a Wheatstone bridge configuration. A post (12a, 22c, 28c, 34e, 50b, 62a, 64a, 68b) extends outwardly from the first body for attachment to the first frame. A second body is formed with a force transfer portion (14a, 24g, 30d, 36b, 52a, 70a) permanently attached to the first body along an outer periphery circumscribing the sense surface. The piezoresistors are electrically connected to conditioning electronics received in a chamber formed between the two bodies. The effects of parasitic loads on the sense element are minimized by selected placement of the piezoresistors on the sense surface. Several variations are disclosed for attaching the sensor to the first and second frames and both longitudinally and laterally extending electrical connectors are shown.

A compliant interface (14,16) for vehicular seat weight sensors minimizes parasitic stresses affecting sensor output. In one embodiment, an integral compliant interface (14) has an annular flange (14a) attached to a post extending from the sensor body with a first compliant member (14r) disposed between the annular flange and an upper elongated flange (14h) of a mounting bracket (14l) and a second compliant member (14s) disposed between the annular plate and a lower elongated flange (14k) to allow pivotal movement of the sensor limited by a motion stop member (14f) of annular flange (14b) engaging the lower flange. An overload cage (14u) may be placed over the sensor and attached to an additional flange (14l) to contain the sensor in the event of a failure of the mount in a catastrophic high speed crash. According to another preferred embodiment, an interface having upper and lower body members are formed with a sensor post receiving bore (16c) for attachment to the post. The body members are formed with spaced apart, radially extending face surfaces, each formed with an annular recess aligned with each other and with a compliant member received therein and fixed to the respective body members and extending beyond the face surfaces. The interface is received through a bore of a support plate to which the sensor is mounted with the compliant members engaging opposite face surfaces of the support plate allowing limited pivotal motion and with a compliant member limiting lateral movement of the interface relative to the support plate.

A source code editor is used to develop multilanguage documents while providing the advanced editing functionality of secondary editors and without requiring the programmer to explicitly open and interface with the secondary editors. The multilanguage document is presented to the user in a primary application view of the primary editor. Code segments written in different languages are identified and sent to the appropriate secondary editors, which in turn create secondary documents that are transparent to the programmer. As edits are made to the primary application view of the document, the edits are replicated by the secondary editors behind the scene. Functionality that is enabled by the secondary editors, such as syntax coloring, auto-completion, and validation is identified by the primary editor and replicated in the primary application view, so as to appear as if the primary editor is inherently configured with the leveraged functionality of the secondary editors.
摘要:
An occupant weight sensor (1) for placement between a frame (7) fixed to the chassis of a vehicle and a second frame (8) supporting a vehicle seat has a sense element having a first body (12, 22, 28, 34, 50, 62, 64, 68, 84) formed with a planar sense surface on which are mounted piezoresistors electrically connected in a Wheatstone bridge configuration. A post (12a, 22c, 28c, 34e, 50b, 62a, 64a, 68b, 84g) extends outwardly from the first body for attachment to the first frame. A second body is formed with a force transfer portion (14a, 24g, 30d, 36b, 52a, 70a, 94a) permanently attached to the first body along an outer periphery circumscribing the sense surface. The piezoresistors are electrically connected to conditioning electronics received in a chamber formed between the two bodies. The effects of parasitic loads on the sense element are minimized by selected placement of the piezoresistors on the sense surface. In one embodiment, attachment stresses of an electronic module assembly (88) are isolated from the sense surface by attaching the assembly to a support ring end wall (86a) welded to a portion of the first body removed from the sense surface and providing a control gap between the support ring and the sense surface. Several variations are disclosed for attaching the sensor to the first and second frames and both longitudinally and laterally extending electrical connectors are shown.
