Abstract: A caliper for a fixed twin rotor disc brake includes a relatively fixed body, two yokes movable axially with respect to the body, formations defined on the yokes for receiving four brake pads for respective application to rotor sides, and an actuator adapted to urge the yokes relatively axially. One of the yokes is operable to urge two of the four brake pads in a first axial direction, the other of the yokes is operable to urge the other two of the four brake pads in a second, opposite axial direction. The four brake pads are positioned on a first side of the actuator in the first axial direction.

Abstract: A system and method is provided for resolving a pivot point via touchless interaction. It applies to situations where one end of a rigid object is inaccessible but remains stationary at a pivot point, while the other end is free to move and is accessible to an input pointing device. As an example, the rigid object can be a leg bone where the proximal end is at the hip joint and the distal end is at the knee. The system comprises a wand and a receiver that are spatially configurable to touchlessly locate the pivot point without contact. The receiver tracks a relative displacement of the wand and geometrically resolves the location of the pivot point by a spherical mapping. The system can use a combination of ultrasonic sensing and/or accelerometer measurements. Other embodiments are disclosed.

Abstract: A system and method of touchless interaction is provided for resolving a pivot point of an object where direct placement of a sensor at the pivot point is not practical. It applies to situations where the pivot point of a rigid object is inaccessible but remains stationary, while the other end is free to move and is accessible. The system maps the object's pivot point by way of an external sensor that detects constrained motion of the rigid object within a hemispherical banded boundary. It can also detect a geometric pattern and acceleration during the constrained motion to compensate for higher order rotations about the pivot point. Other embodiments are disclosed.
