摘要:
The invention is a distribution block assembly that contains replaceable sleeves and pistons that are suitable for use at high fluid pressures. The conventional distribution block assembly can be altered to include end plugs and these replaceable sleeves having designated precise quantity of lubricant distribution so that the user can alter the distribution levels by changing the replaceable piston/sleeves and allowing for users to fix excessively worn pistons without having to dissemble the entire distribution block. The use of these piston/sleeve assemblies transforming conventional distribution blocks making them more versatile and reducing the costly expense of manually replacing of the entire distribution block.

An adjustable canopy bracket for adjustably supporting a canopy to a roll bar of a vehicle, including a lower bracket plate securely positionable about a lower portion of a roll bar member of the roll bar; an upper bracket plate securely positionable about an upper portion of the roll bar member, the upper bracket plate engageable with a forward portion of the canopy; and an adjustable height mechanism engageable with a rearward portion of the canopy, the adjustable height mechanism operable with a rearward portion of the upper bracket plate, wherein adjusting the adjustable height mechanism raises and lowers the rearward portion of the canopy to provide a desired angle of the canopy relative to the roll bar member. An adjustable canopy for attaching to a roll bar of a vehicle is also disclosed and claimed.

A method of performing spectroscopy in a Transmission Charged-Particle Microscope comprising: a specimen holder; a source, for producing a beam of charged particles; an illuminator, for directing said beam so as to irradiate the specimen; an imaging system, for directing a flux of charged particles transmitted through the specimen onto a spectroscopic apparatus comprising a dispersing device for dispersing said flux into an energy-resolved array of spectral sub-beams, the method comprising: using an adjustable aperture device to admit a first portion of said array to a detector, while blocking a second portion of said array; providing; using a radiation sensor in said flux upstream of said aperture device to perform localized radiation sensing in a selected region of said second portion of the array, simultaneous with detection of said first portion by said detector; using a sensing result from said sensor to adjust a detection result from said detector.

A system and method for transmission electron microscopy is provided. The sample can be examined from multiple directions using an electron beam in a transmission electron microscope. The sample has at least three observation faces that are not parallel to each other with the thickness of the sample orthogonal to each of the observation faces being less than 200 nm. The sample is mounted on a needle that is needle rotatable about more than one axis so the needle can orient at least three of the observation faces to be normal to the electron beam of the electron microscope for observation.

The present invention provides a plasma ion beam system that includes multiple gas sources and that can be used for performing multiple operations using different ion species to create or alter submicron features of a work piece. The system preferably uses an inductively coupled, magnetically enhanced ion beam source, suitable in conjunction with probe-forming optics sources to produce ion beams of a wide variety of ions without substantial kinetic energy oscillations induced by the source, thereby permitting formation of a high resolution beam.

A multiple laser sight system for an archery bow or the like configured so that the multiple laser systems can be calibrated together and having features such that the user can use one laser system during the day and one laser system during the light. The laser sight is further configured to not interfere with the optional use of conventional sighting pins and the use of evening infrared systems, like the prior art use of night vision goggles.

The invention relates to a method for analyzing the output signal of a silicon drift detector (SDD). A SDD is used for detecting X-rays emitted by a sample as a result of impinging radiation.The signal of a SDD comprises a number of randomly spaced steps, in which the step height is a function of the energy of the detected X-ray photon.The variance in step height is a function of the averaging time that can be used to determine the plateau between steps: averaging over a short interval results in more uncertainty of the plateau value than a long interval. By according a weight factor, a function of the variance such that a step with low variance (high reliability) is associated with a larger weight factor than a step with high variance (low reliability), measurement values with a low variance are emphasized. This results in better resolved spectra.

A check valve includes an internal liquid trap that prevents the backflow of gas and debris from degrading the valve. The internal liquid trap can be formed by internal passages within a valve housing. One embodiment includes a plurality of concentric fluid passages, connected by a set of radial conduits.

A transmissive lens in a charged particle beam column for detecting X-rays and light is provided. The final lens may include elements that are transmissive for X-rays for EDS imaging and analysis or elements that are transmissive for light for cathodoluminescent (CL) imaging and analysis. The final lens may be constructed and arranged to include elements that are transmissive for both X-rays and light for combined EDS and CL imaging and analysis.
摘要:
A computer-implemented method routes a video relay service call to a call queue corresponding to a preferred language after receiving an input from a user to initiate a video relay service call. The preferred language may be stored in connection with the phone number being called, and the system automatically routes the video relay service call to a call queue for one or more sign language interpreters fluent in the language associated with the telephone number. If there is no default language associated with the phone number being called, the caller can be asked for a language, or a default language can be used.
