Abstract: A method of operating a mobile remotely controlled ground robot in difficult terrain. Rear driven tracked arms of the robot are pivoted rearward and upward to trail main driven tracks of the robot at a fixed angle relative to and above the ground. The main tracks of the robot are driven forward to traverse the ground. An obstacle is traversed by driving the main tracks to traverse the obstacle pivoting the forward end of the robot upwards and at least one of the rear driven tracks are driven and engaging the ground and/or obstacle to advance the robot forward over the obstacle and to prevent the robot from tipping over backwards.

Abstract: A system for removing parasites from fish includes a conduit through which individual fish pass, a plurality of arms associated with the conduit circumferentially spaced with respect to each other, and a spray nozzle for each arm connected to a fluid source for dislodging parasites from said fish. The nozzles are closely spaced with respect to the fish for more effective treatment. A pre-treatment substance may also be used.

Abstract: A system for removing parasites from fish includes a downwardly angled enclosed conduit through which individual fish freely pass, and two or more spaced sets of arms extending inward from the conduit. There is a spray nozzle for each arm connected to a fluid source for dislodging parasites from the fish. The arms are adjustable relative to the enclosed conduit depending on the size of the fish in the conduit for closely spacing the spray nozzles with respect to the fish without stressing or harming the fish.

Abstract: A battery powered remotely controlled robot is equipped with a drive subsystem for ground travel, a flight subsystem for flight operations, and an obstacle detection subsystem. The robot is configured so that during a mission the drive subsystem is energized to maneuver the robot on the ground for a majority of the mission. The robot is further configured so that upon detection of an obstacle, the flight subsystem is energized to traverse the obstacle. The fight subsystem is energized only to traverse obstacles thus saving battery power and increasing the mission time.

Abstract: A system and method for removing parasites from fish. Individual fish pass in a conduit and a plurality of arms are associated with the conduit circumferentially spaced with respect to each other. A treatment head unit for each arm for dislodging parasites from the fish. The arms are adjusted for closely spacing the head unit with respect to the fish.

Abstract: A ground pressure detonation device includes a housing, a foot coupled to the housing, and an oscillation subsystem associated with the housing configured to oscillate the housing such that the foot impacts the ground with sufficient oscillating force to ensure detonation of one or more pressure sensitive explosive devices in and/or on the ground.

Abstract: A video endoscope system includes a reusable control cabinet and an endoscope that is connectable thereto. The endoscope may be used with a single patient and then disposed. The endoscope includes an illumination mechanism, an image sensor, and an elongate shaft having one or more lumens located therein. An articulation joint at the distal end of the endoscope allows the distal end to be oriented by the actuators in the control cabinet or actuators in a control handle of the endoscope. Fluidics, electrical, navigation, image, display and data entry controls are integrated into the system along with other accessories.

Abstract: A food treatment system and method with a pressurization zone, a dwell zone, and a depressurization zone. A linear pocket feeder includes a number of sealed chambers each housing a food product driven through the pressurization zone, the dwell zone, and the depressurization zone in sequence. The pressurization zone includes at least one purge region to prevent dilution of treatment fluid and also treatment fluid injection regions to pressurize the sealed chambers in a controlled fashion. The depressurization zone includes treatment fluid ejection regions to depressurize the sealed chambers and remove the treatment fluid therefrom in a controlled fashion. The treatment fluid injection regions are in fluid communication with the treatment fluid ejection regions to conserve treatment fluid and to minimize power required for pressurization.

Abstract: An endoscopic imaging system includes a reusable control cabinet having a number of actuators that control the orientation of a lightweight endoscope that is connectable thereto. The endoscope is used with a single patient and is then disposed. The endoscope includes an illumination mechanism, an image sensor, and an elongate shaft having one or more lumens located therein. An articulation joint at the distal end of the endoscope allows the distal end to be oriented by the actuators in the control cabinet. The endoscope is coated with a hydrophilic coating that reduces its coefficient of friction and because it is lightweight, requires less force to advance it to a desired location within a patient.
