    Abstract: The present disclosure provides a camera module for use in a portable electronic device. The camera module comprises a shiftable lens barrel comprising an objective assembly holding coaxially one or more lens elements defining an optical axis. The camera module has a retractable cover window. The lens barrel has an operative state and a collapsed state and the cover window has a corresponding extended and retracted position. The camera further comprises an actuator including a driving motor; a pop-out assembly actuatable by the actuator. The pop-out assembly includes a driving cam configured to be driven rotationally by the actuator, a carrier configured to receive the lens barrel and an image sensor configured to image a field of view of the objective assembly when the lens barrel is in the operative state.

    Abstract: Position sensing units, comprising a magnetic assembly (MA) having a width W measured along a first direction and a height H measured along a second direction and including at least three magnets having respective magnetic polarizations that define along the first direction at least a left MA domain, a middle MA domain and a right MA domain, wherein the magnetic polarizations of each MA domain are different, and a magnetic flux measuring device (MFMD) for measuring a magnetic flux B, wherein the MA moves relative to the MFMD along the first direction within a stroke L that fulfils 1mm ≤ L ≤ 100mm, stroke L beginning at a first point x0 and ending at a final point xmax, and wherein a minimum value Dmin of an orthogonal distance D, measured along the second direction between a particular MA domain and the MFMD, fulfills L/Dmin>10.

    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.
