    摘要： A vehicle brake assembly includes a sensor that detects the amount of movement of certain components within the brake assembly. In the preferred embodiment, a rotary sensor is coupled directly with the generally S-shaped cam member and provides signals that indicate the total amount of rotary movement of the cam member during braking applications. These signals provide information indicative of the amount of slack or stroke during braking applications and provide indications of the conditions of brake linings associated with the brake shoes within the brake assembly. The sensor information preferably is communicated to a vehicle operator in a manner that indicates whether an inspection or maintenance of the braking system is advisable

    摘要： A brake shoe assembly includes a backing plate and a brake lining. The brake lining has an interface surface abutting the backing plate and a frictionally engaging surface that frictionally contacts a vehicle. The brake lining is provided with a temperature measuring system embedded therein which may measure the temperature directly on the frictionally engaging surface of the brake lining material by way of a heat pipe. The temperature measuring device communicates with a control that activates a signal when a predetermined abnormal degree of heat is generated on the frictionally engaging surface of the brake lining. Thus, a fault in the braking mechanism is indicated.

    摘要： An isolator to prevent transmitted vibrations includes a ring which fits within a shaft opening of a housing. A bearing is received within the isolator and a shaft is received within the bearing. The vibrations are decoupled from a vibration transmission path by the different material of the isolator. The isolator is preferably manufactured of a rigid laminate material dissimilar to the housing material. Another embodiment of the present invention integrates the isolator directly into the bearing assembly. By manufacturing the outer member of the bearing assembly of the laminated material, the outer member similarly breaks the transmission path of vibrations without the need of the additional member. Noise is thereby substantially prevented from reaching, and from being amplified by, the housing. This greatly reduces the resulting noise and vibration.

    摘要： A brake shoe assembly includes a brake lining and a brake lining wear sensor. The brake lining has a predetermined thickness which gradually wears away as the brake shoe assembly is used to brake a vehicle. The brake lining wear sensor has a pair of spaced electrical conductors and an electrical resistance located across the pair of spaced conductors for indicating the thickness of the brake lining. The brake lining wear sensor is positioned to wear away concurrently with the brake lining, thereby continuously changing the electrical resistance across the pair of spaced conductors. In this manner, the electrical resistance across the pair of spaced conductors is used to determine the thickness of the brake lining. The brake lining wear sensor can be assembled in alternative embodiments as disclosed.

    摘要： A window sliding mechanism such as that which is used in passenger car doors incorporates a system to reduce friction between a window and its respective seal. A channel provided with air holes is fitted along the window edges that ride within a conventional seal. Alternatively, the air holes could be provided in the seal itself. Air is supplied to the air holes by way of a reservoir or small pump attached to the window sliding mechanism. Controlled air flow reduces the friction generated during window travel. In another embodiment, the system to reduce friction is an oscillating device provided to a conventional window sliding mechanism. The oscillating device is powered by a low cost piezo device. The oscillating device would cause the window to vibrate, thereby reducing the friction generated during window travel.

    摘要： A pressure detector including a fiber optical cable woven through a ladder-like structure which is then encapsulated and surrounded by a cover. Light transmitted through the fiber optic cable is diminished to a value less than a threshold value upon the occurrence of microbending caused by pressure applied at any location along the length thereof. The rungs of the ladder-like structure are sized and spaced to provide a proper locus about which microbending may be produced. In addition, the rungs may be round in cross-section and/or otherwise shaped to enhance the sensitivity of the system.

    摘要： Four embodiments of a reluctance type rotational speed sensor are disclosed. In the first embodiment, an annular magnet circumscribes a sensing coil having a unitary rotor nested within it, and is disposed between two elements which comprise the stator. In a second embodiment, a magnet is disposed between two halves which comprise a rotor, the entire assembly nesting within a sensing coil and being disposed between the two stator elements. In the third embodiment, the rotor carries multiple magnets in an axially opposed position with respect to teeth formed on the stator. The magnetic flux in the magnetic circuit increases and decreases as the rotor magnets alternate between aligned and non-aligned positions enabling measurement of angular speed in accordance with the increase and decrease of magnetic flux. Any of the first three embodiments may be used, with minor modifications, in environments where a rotating shaft turns within a stationary bore, or where a rotting bore turns about a stationary shaft. The fourth embodiment incorporates the features of the first three and further includes a caliper-like stator and coil assembly which may be removed for service without requiring extensive disassembly.
