Abstract: A device including a platform and a drill connected to the platform. The device also includes a power source for powering the drill. The device also includes a cable connected to a cable reel and to the drill. The device also includes a stinger having a first end connected to the platform and a second end opposite the first end. The stinger includes a beam extending outwardly from the platform. The second end of the stinger connects to the cable. The stinger is configured to guide a position of the cable, relative to the platform, as the cable moves relative to the platform and relative to the stinger.

Abstract: A system including an engine connectable to a time variant working load. A motor is connected to the engine, and a variable frequency drive is connected to the motor. A system controller is connected to the variable frequency drive, and is programmed to command the variable frequency drive to change a selected mode of the motor according to an operational state of the engine. An electrical generation mode includes the motor operating as a generation load on the engine when the working load falls to an intermediate load below the operational load. A generation load combined with the intermediate load includes about the operational load. A standby mode includes the motor operating as a standby load on the engine when the working load about equals the operational load. A drive mode includes the motor applying mechanical power to the engine.

Abstract: A vehicle including a chassis and an engine connected to the chassis. The vehicle also includes a torque converter directly connected to the engine. The vehicle also includes a motor having a first side and a second side directly connected to the torque converter, opposite the engine. The motor further includes a rotor having an annular shaft cavity. The motor further includes a first diameter equal to or smaller than a second diameter of the torque converter. The motor is connected to the torque converter via the annular shaft cavity. The vehicle also includes a drive shaft directly connected to the motor, opposite the torque converter. The drive shaft is operatively disposed in the annular shaft cavity. The vehicle also includes a transmission connected to drive shaft. The vehicle also includes a differential connected to the transmission. The vehicle also includes wheels connected to the differential.

Abstract: A vehicle including a chassis and an engine connected to the chassis. The vehicle also includes an alternator connected to the engine and a drive system connected to the alternator. The vehicle also includes a number of wheel motors connected to the drive system. The vehicle also includes a number of wheels connected to the wheel motors. The drive system includes a number of modules. Each of the modules is directly connected to at least one other module of the modules. Each of the modules is interchangeable with another of the modules. Each of the modules includes one or more switches for controlling a mode of operation of each of the modules. The one or more switches of each of the modules are set to control an electrical interface between the drive system and electrical components of the vehicle, the electrical components including at least the wheel motors.
