Abstract:
Method of making a droplet-generating device. In the method, a first-droplet generating device may be produced. The first droplet-generating device may include a molded portion created at least in part with a mold and also may include a plurality of droplet generators each formed at least in part by the molded portion. A set of droplets may be generated with each of one or more of the droplet generators. A property of at least one set of generated droplets may be determined. The mold may be modified based on the property. A second droplet-generating device may be produced that includes a molded portion created at least in part with the modified mold.
Abstract:
Methods and systems for fabricating platelets of a monochromator for X-ray photoelectron spectroscopy (XPS) are disclosed. For example, a method of fabricating a platelet of a monochromator for X-ray photoelectron spectroscopy involves placing a crystal on a stage of an X-ray measuring apparatus, the crystal having a top surface. The method also involves measuring, by X-ray reflection, an orientation of a crystal plane of the crystal, the crystal plane beneath the top surface of the crystal and having a primary axis. The method also involves measuring a surface angle of the top surface of the crystal by measuring a light beam reflected from the top surface of the crystal.
Abstract:
A lifting connector to facilitate the Sifting of wear parts used on earthmoving equipment is mechanically secured to a hole in the wear part. The wear part has a latching formation to maintain the head of the connector in a preferred orientation so that it is in the proper service position for connecting the lifting connector to a lifting device. The wear part can be safely maneuvered onto and off of the earthmoving equipment while secured to the lifting device.

Abstract:
A self-calibrating powered air purifying respirator (PAPR). The PAPR comprises an electric motor mechanically coupled to a blower, an air flow sensor, and a controller coupled to the air flow sensor and to the electric motor. The controller is configured to automatically execute a one-time self-calibration by driving the electric motor to a predefined operation point, receiving an indication from the air flow sensor, determining a reference parameter based on the indication from the air flow sensor, and storing the reference parameter, wherein after completion of the one-time self-calibration the controller controls the electric motor based on the stored reference parameter.

Abstract:
A method of measuring the performance of a spectroscopy system comprising obtaining a plurality of component spectra for each component of a set of components that are to be identified by the system, the component spectra obtained for variations of at least one factor that affects the component spectrum. Sample spectra and then simulated, each sample spectrum simulated for a corresponding potential sample using at least one different component spectrum and/or a different amount of at least one of the component spectra to that used to simulate the other sample spectra. The sample spectra are analysed to obtain, for each sample spectrum, a measured quantity and/or quality for a characteristic of the corresponding potential sample and a measure of performance generated based upon the measured quantities and/or qualities. The invention also concerns apparatus for carrying out this method.
Abstract:
An exposure apparatus is equipped with a table (WTB) which holds a wafer (W) and is movable along an XY plane and has a grating (RG) provided on its rear surface, an encoder (70A) which irradiates a first measurement beam on the grating (RG) from below and measures a first position information of the table when the table moves in a predetermined range, and another encoder (80A) which has a head section (62A, 62C) provided in a frame (BD) and irradiates a second measurement beam on a different grating (39 1 , 39 2 ) on the table from the head section and can measure a second position information of the table, concurrently with measurement of the first position information by the encoder (70A) when the table moves in a predetermined range. A controller drives the table, based on position information having a higher reliability of the first and the second position information.
