A device and a method for wavefront measurement of an optical imaging system, and a microlithography projection exposure machine that is equipped with such a device. The device has a wavefront generating unit that includes an optical element (1) with an object-side periodic structure (2), and a light source unit (20,21) for illuminating the object-side periodic structure with the aid of a measuring radiation. The device also has a detector unit that is arranged on the image side of the imaging system to be measured and that includes an optical element (3) with an image-side periodic structure, and a detector element (52, 52a, 52b) for detecting an overlay pattern of the imaged object-side periodic structure and image-side periodic structure. The wavefront generating unit is designed to restrict the angular spectrum (6) of the measuring radiation emanating from a respective field point (7), the design being such that the measuring radiation emanating from the respective field point illuminates only in each case a specific subregion of a pupil plane of the optical imaging system.

A replaceable cartridge has an at least one sharpened edge thereon and an at least one cartridge tab extending therefrom, the at least one cartridge tabs mating and penetrating and coupling with the at least one receiving section. And a locking mechanism is engaged when the replaceable cartridge is brought into proximity with the main blade body and the at least one receiving section is penetrated and coupled by the at least one cartridge tab.

A method and device for the production of books, including: moving book blocks successively along a conveying section of a book production line; supplying a stack of book cases to the book production line; identifying a marking on each of the book blocks and the book cases; transmitting an identified marking on at least one book case to a machine control of the book production line; assigning a dataset stored in the machine control for a sequence of book cases to the supplied stack; determining a sequence in the machine control for book blocks positioned on the conveying section; comparing the dataset for the sequence of the book cases to the sequence of the book blocks; and removing and / or supplying at least one book block from or to the conveying section if the sequence of the book blocks deviates from the sequence of the book cases using the machine control.

There is provided a device for electrically conductive contacting of a pipe having a band shaped metallic clamp (2) with two end parts (6, 7), wherein the clamp is equipped with parts of a closing device (11, 13, 14) at both end parts. The device has a separator (4) made from electrically conductive material, wherein the separator is deformable under pressure and wherein the separator is attached to the inner surface of the clamp. The device further comprises insulating material (3), wherein the clamp is embedded in the insulating material leaving free the inner surface required for making contact with the pipe. Furthermore, the embedded material leaves free both end parts of the clamp enabling a direct contact between both end parts in an assembly position of the device around the pipe.

The present invention relates to a pair of glasses with polarized or prescription lenses that can be adjusted to provide two different looks. Rotatable side arms connected to the main frame through a leg seat and a rotating secondary frame provide a mechanism to interchange the interior and exterior sides of the glasses. A correct lens orientation indicator on the secondary frame ensures correct configuration. In addition, the proposed mechanism offers two folding styles, in the first one both side arms are folded next to each other at the same side of the main frame. In the second, the side arms are folded on opposite sides of each other. Furthermore, the present invention provides a simple mechanism to turn smart glasses on and off. If the camera placed on the side arm is facing outwards, the smart glasses turns on. When the camera faces inwards, the smart glasses turns off.

A power factor correction (PFC) boost circuit. The PFC boost circuit can include a first switching device, a second switching device, a first gate driver coupled to the first switching device, a second gate driver coupled to the second switching device, and a PFC controller configured to control the first and second gate drivers. The PFC controller will utilize a new technique, referred to herein as “predictive diode emulation” to control the switching devices in a desired manner and to overcome inefficiencies and other problems that might arise using traditional diode emulation. The PFC controller is configured to operate in synchronous and non-synchronous modes.

A system, apparatus and methods for transmitting video and audio data over twisted pairs are described. A differential signal that contains video color information is transmitted over each twisted pair. Data representing digital samples of at least one audio signal is transmitted on two or more of the twisted pairs as a common mode signal.

A method and a turbine part having a coating with a matrix layer that includes a high temperature resistant hydrophobic polysiloxane filler, wherein the coating has superior mechanical strength and temperature resistance.

A hydraulic system for a vehicle, comprising a hydraulic actuation device for moving one or more moveable components of the vehicle. The actuation device comprises a hydraulic pump with an associated drive means, a reservoir for hydraulic fluid as well as one or more hydraulic actuators connected to the pump through hydraulic hoses. The hydraulic actuators act on the one or more moveable components. The pump is designed to supply pressurized hydraulic fluid to the one or more hydraulic actuators. A pressure ripple reduction device for reducing pressure ripples in the hydraulic fluid originating from the hydraulic pump is provided, having an expansion chamber.

The invention relates to mass spectrometers having secondary electron multipliers with series of discrete dynode stages. The invention particularly relates to an operation with extended dynamic measuring range and extended lifetime. The invention is based on not adapting the dynamic measuring range by control of the gain of the trans-impedance amplifier, nor controlling the multiplier operating voltage, which both are usually too slow, but alternating a number of active and passive dynode stages of a discrete dynode multiplier. Each dynode stage is connected to a discrete voltage supply circuit, being able to be de-energized and short-cut; the multiplier gain is feedback-controlled by energizing or short-cutting dynode stages, serially from the end of the multiplier, as a function of a last measured ion signal; and the multiplier has a single trans-impedance amplifier and a single analog-to-digital converter, measuring and digitizing the output current of the last active dynode stage.
