Abstract: A system and method for remotely monitoring a fleet of material handling vehicles is provided. The system and method include a remote monitoring station with a display interface and a server and one or more material handling vehicles with a sensor system and a vehicle controller with a processor and a memory device. The vehicle controller generates time-sequenced data based on received sensor data to create a composite image based on historical composite data and transmits the composite image in real-time to the display interface of the remote monitoring station.

Abstract: An oscillation reduction tool configured to prevent or reduce high frequency torsional oscillation by torsionally decoupling a rotary steerable system from a bottom hole assembly, which includes a drilling motor. The tool may convert high frequency torsional oscillation into an internal axial movement without axial displacement of the tool's outer housing. The oscillation reduction tool may flatten an amplitude of high frequency torsional oscillation spikes throughout a spring arrangement. The mechanical energy associated with the internal axial movement is reduced through an internal shock absorbing mechanism, such as fluid movement through a nozzle or annular space. The oscillation reduction tool functions to reduce high frequency torsional oscillation independent of the weight on the bit of the drill string.

Abstract: An apparatus and method for monitoring the status and health of a fleet of vehicles operating in a common space. A centralized monitoring operator receives status information and has the capability to independently interact with each vehicle in the fleet.

Abstract: A vibration assembly includes a valve above a rotor and stator. The rotor rotates within the stator as fluid flows therethrough. The valve includes a rotating valve segment, which rotates with the rotor, and a non-rotating valve segment each including at least one fluid passage. In an open position, the fluid passages of the valve segments are aligned and a fluid flows through the valve. In a restricted position, the fluid passages of the valve segments are partially or completely unaligned, thereby creating a pressure pulse that is transmitted through the drill string or coiled tubing above the valve. The valve may further include an inner sleeve and an outer sleeve surrounding the non-rotating valve segment. The inner and outer sleeves allow axial sliding but prevent rotation of the non-rotating valve segment. The assembly may further include a lower thrust bearing at a lower end of the rotor.

Abstract: A downhole vibration assembly includes a valve positioned above a rotor that is disposed at least partially within a stator. The rotor is operatively suspended within an inner bore of a housing and configured to rotate within the stator as a fluid flows through the vibration assembly. The valve includes a rotating valve segment and a stationary valve segment each including at least one fluid passage. The rotating valve segment rotates with a rotation of the rotor. In an open position, the fluid passages of the valve segments are aligned and a fluid flows through the valve. In a restricted position, the fluid passages of the valve segments are partially or completely unaligned, thereby temporarily restricting the fluid flow through the valve to create a pressure pulse. The unobstructed pressure pulse is transmitted through the drill string or coiled tubing above the valve.

Abstract: The present invention discloses a cutting guide that permits the use of a power saw in trimming roofing materials in the installation of those roofing materials. The cutting guide may be constructed as an accessory or as a contiguous roofing material cutting apparatus and generally comprises a mounting plate for coupling a power saw to the cutting guide, a post extending downwardly from the mounting plate in general alignment with a blade of the power saw, and a base that supports the power saw and cutting guide and which has at least one lateral edge that is arranged substantially parallel with the blade of the power saw at a predetermined offset distance therefrom. The cutting guide of the present invention may be readily configured to trim roofing materials such as shingles, membranes, shakes, or tiles in roof valleys, at ridges, and at the gable end of a roof.
