Abstract: An ophthalmic laser surgical system for treating an eye includes a laser device, one or more cameras, and a computer. The eye has anatomical features, including the cornea with the anterior corneal surface. The laser device directs a laser beam towards the eye. A camera generates images of the anatomical features, including the anterior corneal surface. The computer facilitates docking a patient interface onto the eye by accessing eye information describing the eye. The eye information comprises an eye model describing the anatomical features. The computer determines from the eye model the predicted corneal surface position when the eye is aligned to dock the patient interface onto the eye. The computer detects from the images the actual corneal surface position prior to docking the patient interface onto the eye, and compares the predicted corneal surface position with the actual corneal surface position to detect misalignment.

Abstract: A multiple particle beam microscope and an associated method can provide a fast autofocus around an adjustable working distance. A system can have one or more fast autofocus correction lenses for adapting, in high-frequency fashion, the focusing, the position, the landing angle and the rotation of individual particle beams upon incidence on a wafer surface during the wafer inspection. Fast autofocusing in the secondary path of the particle beam system can be implemented in analogous fashion. An additional increase in precision can be attained via fast aberration correction mechanism in the form of deflectors and/or stigmators.

Abstract: A power tool for chiseling and drilling includes a housing, a motor disposed inside the housing, and a pneumatic percussion mechanism. An operation mode selector switch is disposed on the housing and has a first operation mode setting and a second operation mode setting where the first operation mode setting activates the pneumatic percussion mechanism and the second operation mode setting deactivates the pneumatic percussion mechanism. A valve has an inlet-port formed inside the guiding tube and an outlet-port formed outside the guiding tube where the valve is connected to the operation mode selector switch. The valve is closed in the first operation mode setting which disables an air exchange between the inlet-port and the outlet-port and the valve is open in the second operation mode setting which enables the air exchange between the inlet-port and the outlet-port.
