Filed:

Apr 6, 2018

Appl. No.:

15/947055

Inventors:

- Tewksbury MA, US
Michael Bush - Arlington MA, US
Wayne Minter - Peabody MA, US
Neil P. Hagerty - Westford MA, US
Artur Malinouski - Boston MA, US

International Classification:

G01J 3/02
G01N 21/71
G01N 21/13

Abstract:

Devices and methods are disclosed that allow for analysis with simplified sample preparation. Of particular relevance is the analysis of wire samples (e.g., weld wires) using laser induced breakdown spectroscopy (LIBS) or optical emission spectrometry (OES). Representative devices can isolate a sample, such as in a sealed, inert environment in an analytical instrument. These devices may include first and second sample end attachments connected to a body, which has a connecting portion that may be configured for alignment with the face of the instrument. The body may also include a rotatable cap, and the sample end attachments may be joined to this cap (e.g., at opposite ends thereof) to allow adjustment of the angular position of the sample, relative to the connecting portion, which in use may be affixed to the instrument.

International Classification:

G01J 3/443
G01J 3/02

Abstract:

Methods and apparatus for laser induced breakdown spectroscopy (LIBS) sample chamber. An apparatus includes a sample chamber, a laser source connected to an excitation optics assembly, the excitation optics assembly connected to a first port on the sample chamber, a collimator assembly connected to a spectrometer, the collimator assembly connected to a second port on the sample chamber, and a first lens tube positioned on the first port and a second lens tube positioned on the second port, the first lens tube protecting the first port connected to the excitation optics assembly and the second lens tube protecting the second port connected to the collimator assembly from particles emitted when a laser pulse from the laser source ablates a surface of a target sample and generates a plasma.

International Classification:

B60R 19/16
B25J 19/00
B25J 19/06

US Classification:

701 23, 293 19, 901 1, 901 49

Abstract:

A roller assembly provides collision protection and stability to a mobile robot. The roller assembly includes a shaft forming an axis about which the roller assembly can rotate. The shaft has opposite ends configured to be supported by bearings in the robot. The roller assembly also includes an impact absorbing layer coaxially covering the shaft. It further includes a shell coaxially covering the impact absorbing layer having a lower coefficient of friction than the impact absorbing layer for providing low sliding friction.
