    Abstract: Systems and methods for eliminating or mitigating T-effects on Hall sensors. A system may comprise a magnet-coil arrangement for providing a relative movement therebetween to obtain a relative position, a Hall sensor for sensing the relative movement, a temperature sensor located in proximity of the Hall sensor for providing temperature sensing, and a controller having two or more channels coupled to Hall sensor and to the temperature sensor and configured to control the relative movement and to provide, based on the temperature sensing, a temperature correction input to the Hall sensor for compensating a temperature effect on the Hall sensor sensing.

    Abstract: Actuators for providing an extended two-degree of freedom rotation range to an optical path folding element (OPFE) such as a prism or mirror in mobile devices such as smartphones, comprising a yaw sub-assembly having a yaw rotation axis, a pitch sub-assembly carrying the OPFE, the pitch sub-assembly including a pivot rotation mechanism and having a pitch rotation axis; and a stationary sub-assembly, wherein the actuator is operative to rotate the OPFE in two rotation directions, a first rotation for yaw around the yaw rotation axis and a second rotation for pitch around the pitch rotation axis, and wherein the rotation for pitch includes rotation using the pivot rotation mechanism.

    Abstract: Rotation mechanisms for rotating a payload in two, first and second degrees of freedom (DOF), comprising a static base, a first rotation arm coupled mechanically to the static base through a first rotation joint and used for rotating the payload relative to the static base around a first rotation axis that passes through the first rotation joint, a second rotation arm coupled mechanically to the static base through a second rotation joint and used for rotating the payload relative to the static base around a second rotation axis that passes through the second rotation joint, and a follower member rigidly coupled to the payload and arranged to keep a constant distance from the second rotation arm, wherein the rotation of the first arm rotates the payload around the first DOF and the rotation of the second arm rotate the payload around the second DOF.
