Abstract: A gamma-ray analysis system is described for analyzing gamma-ray emitting radionuclides. The gamma-ray analysis system includes an analytical apparatus having a gamma-ray detector in operative communication with a modular and scalable shield assembly that encases a sample container having a sample to be tested. The detector communicates data to an electronic interface device that converts the data from an analog format to a digital format before a controller transmits the data to a central laboratory for further data processing, analysis and conclusion by qualified laboratory analysts. The controller runs an application software package on a graphic user interface that allows simple steps for conducting testing and data acquisition by the end user, while permitting real time data transmission between the field site and the central location. Functions were implemented for ensuring laboratory quality results while removing knowledge and experience requirements of an end user.

Mounting, using a connection between the service processor and the host system, the device within the host system, and performing the set of diagnostics on the host system.

Abstract: A mooring system for a floating structure (1) in which a floating structure or fixed tower is provided with a turntable (80). A floating structure is moored to the turntable via at least one rigid arm (51,51?) and two tension members (41, 41?). The rigid arm is provided on one end with a ballast weight (61, 61?) and includes a damping system formed of least two separated liquid tanks (70, 70?) that are partly filled with liquids and placed at the same distance from the horizontal center line (100). The tanks (70, 70?) are fluidly connected with each other so that liquid can be exchanged between the tanks damps a swinging yaw motion of the rigid arm (51, 51?) around the vertical axis of the turntable (80).

Abstract: Reinforced ground cover mats are used to facilitate the passage of heavy equipment and vehicles on wet or disturbed ground. The ground cover mats are comprised of boards contained within a peripheral metal frame having two substantially parallel opposing end members that are I-beams, the upper and lower horizontal flanges and vertical webs of which define an outer slot into which a reinforcing member is inserted such that the reinforcing member contacts the vertical web and upper and lower horizontal flanges. Flanged caps may be attached to the ends of the reinforcing member to retain a sling looped around the reinforcing member for pulling the mat.

Abstract: The invention is directed to reinforced ground cover mats which can be used to facilitate the passage of heavy equipment and vehicles on wet or disturbed ground. The ground cover mats are comprised of boards contained within a metal frame. A structural support in the form of an I-beam encases the boards and frame on one side, and a tubular member such as a pipe on the other side, thereby increasing the strength at the middle of the mat ends. Further, the tubular member can be modified at its ends to facilitate insertion of a sling and stacking of adjacent mats. The mat also comprises means for lifting, including passages through which chains or cable may be threaded, lifting shackle assemblies or pear link assemblies.

Abstract: The frequency of the pulse width modulator within a step motor control circuit is increased above a base frequency under defined conditions to enable more accurate construction of the phase current waveform for preventing mid-range resonance. The PWM frequency is stepped between frequencies by a fixed amount above the base frequency, to prevent the excitation of system harmonics and prevent step motor operational instability.

Abstract: The current in each phase of a multi-phase step motor is monitored and the excess phase current above the set point current, as required on a cycle-by-cycle PWM basis, is reduced thereby bringing each phase current down to the set point. The PWM frequency is automatically adjusted to maintain a minimum number of PWM edges within a portion of the current waveform. A maximum charge/discharge time is specified as a percentage of the PWM period. These provide an accurate independent current control within each phase of a multiphase step motor.
