    Abstract: A disc brake testing apparatus comprises operating means operable to operate pad moving means of the disc brake to urge pads of the brake towards the disc thereof. The operating means operable to urge the pads against the disc with a higher pressure sufficient to cause the pads to maintain constant contact with the disc and apply a significant braking force thereto. In order to simulate conditions which cause disc thickness variation, the operating means is alternatively operable to urge the pads against the disc with a lower pressure selected to cause the pads to make intermittent contact with the disc during each revolution of the disc.

    Abstract: Aspects of the present invention provide an optical leveling system and method. Embodiments of the present invention utilize a pendulum having an opening through which light can pass to create varying light patterns in response to movement of the pendulum relative to an enclosure. The varying light patterns are detected and utilized to determine the position of the pendulum relative to the enclosure, which can be expressed as degrees and increments of degrees of deviation from a level condition. Embodiments of the present invention can be utilized, for example, to remotely monitor whether a mainframe computer system is level and, if necessary, alert service personnel.
