Abstract: Scanning Tele cameras (STCs) based on two optical path folding element (OPFE) field-of-view scanning and mobile devices including such STCs. A STC may comprise a first OPFE (O-OPFE) for folding a first optical path OP1 to a second optical path OP2, an O-OPFE actuator, a second OPFE (I-OPFE) for folding OP2 to a third optical path OP3, an I-OPFE actuator, a lens, a lens actuator and an image sensor, wherein the STC has a STC native field-of-view (n-FOVT), wherein the O-OPFE actuator is configured to rotate the O-OPFE around a first axis and the I-OPFE actuator rotates the I-OPFE around a second axis for scanning a scene with the n-FOVT, wherein the lens actuator is configured to move the lens for focusing along a third axis, and wherein the first axis is perpendicular to the second axis and parallel to the third axis.

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 1 mm?L?100 mm, 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: Apparatus and methods are described for performing a procedure on a patient's eye. A robotic unit inserts an ophthalmic tool into the eye via an incision in the cornea, such that a tip of the ophthalmic tool is disposed within the eye and a remote center of motion location of the ophthalmic tool is disposed within the incision. The location and the orientation of the tip of a control-component tool are determined based upon data received from one or more location sensors, and the tip of the ophthalmic tool is moved within the eye in a manner that corresponds with movement of the control-component tool. Feedback is provided to an operator that is indicative of a disposition of the remote center of motion location of the ophthalmic tool relative to the incision. Other applications are also described.

The location and the orientation of the tip of a control-component tool that is configured to be moved by an operator is determined, based upon data received from one or more location sensors that are disposed on a control-component arm that is coupled to the control-component tool, and the tip of the ophthalmic tool is moved within the patient's eye in a manner that corresponds with movement of the control-component tool. Force feedback is provided to the operator via the control-component arm. Other applications are also described.

Abstract: Sterile barriers and sensor configurations for a medical device are described. The sterile barriers isolate internal components such as a battery pack or a sensor pack from the environment and the patient.
