Abstract: Techniques described herein relate to a method for identifying downhole conditions during a drilling operation using a vibratory separator. The method includes calibrating a sensor system attached to the vibratory separator by periodically measuring the G-force acting on the vibratory separator functioning under steady-state operating parameters. The method also includes determining the relationship between the G-force acting on the vibratory separator and the flow rate and rate of penetration (ROP) for the drilling operation by measuring the G-force acting on the vibratory separator functioning under different non-steady-state operating parameters.

Abstract: An intrinsically-safe sensor system, as well as a method for assembling the intrinsically-safe sensor system and a method for monitoring sound corresponding to a source using the intrinsically-safe sensor system, are provided herein. The intrinsically-safe sensor system includes a number of sensors, including a microphone, as well as a processor for processing sensor data obtained from the sensors. The intrinsically-safe sensor system also includes a memory component for storing the sensor data obtained from the sensors, a power source, a communication connection for communicably coupling the intrinsically-safe sensor system to a remote computing system, and a connector including internal and external connection regions for internally and/or externally connecting one or more additional devices to the intrinsically-safe sensor system on demand.

Abstract: Methods of increasing efficiency of plunger lift operations and hydrocarbon wells that perform the methods are disclosed herein. The methods include monitoring an acoustic output from the hydrocarbon well. The methods also include calculating a plunger speed of a plunger of the hydrocarbon well as the plunger travels toward a surface region and calculating a discharge duration of a liquid discharge time period during which liquid is discharged from the hydrocarbon well.

Abstract: A system and method for the ultrasonic autonomous detection of a leak in a component are disclosed using at least one source sensor, at least one ambient sensor and a processor. Based upon the detection of high frequency sounds from the sensor, the processor can determine whether or not a leak is present.

Abstract: In one aspect of the present invention, there is provided a video game system including a game controller, a video display and a hand-held control unit. The game controller is coupled to the control unit and the video display. The control unit houses an accelerometer that senses the tilt of the control unit with respect to an axis. The accelerometer produces an acceleration signal indicating the tilt of the control unit with respect to the axis. The game controller processes the acceleration signal to control the movement of a game character on the video display. In another aspect of the present invention, there is provided a video game system that further includes a light sensor housed in the control unit. The light sensor detects one or more light pixels from the video display and produces a detection signal to the game controller. The game controller determines from the detection signal the light pixels detected from the video display.

Abstract: In one aspect of the present invention, there is provided a motion simulator for a video game. The motion simulator includes a base and a platform supported on the base. The platform has first and second sides. First and second motors drive respective first and second shafts. First and second cams are mounted to the respective first and second shafts. First and second cam followers are connected to the platform proximate the respective first and second sides. The first and second cam followers rest on the respective first and second cams such that rotation of either the first or second shaft causes vertical movement of the platform.
