Abstract: A system and an apparatus for positioning a plurality of flexible cleaning lances through tubes penetrating a tube sheet of a heat exchanger tube sheet, includes a smart lance tractor drive, a controller, and a tumble box connected to the controller operable to generate and/or distribute electrical power to the AC induction sensor from an air pressure source, supply electrical power to the controller and distribute pneumatic power to pneumatic motors for positioning the tractor drive on the positioner frame. The smart tractor drive includes sensors for detection of mismatch between expected and actual lance positions, sense lance insertion distance and lance removal and provide automated drive reversal operation to remove blockages within tubes being cleaned.

Abstract: A multiple flexible high pressure fluid cleaning lance drive apparatus includes at least a first drive motor having a first drive shaft, a spline drive roller mounted on the first drive shaft, a plurality of cylindrical guide rollers extending parallel to the spline drive roller, an endless belt wrapped around the spline drive roller and the plurality of guide rollers, and one or more follower roller modules each supporting a plurality of follower rollers for pressing against a single flexible lance. Each follower roller module independently presses its follower rollers toward the endless belt to grip the flexible lance sandwiched therebetween. Each module has an elongated block shaped housing having a central axis, a plurality of pneumatic cylinders and a piston rod carried in each pneumatic cylinder supporting a pair of spaced follower rollers that ride on the flexible lance captured between the endless belt and the follower rollers.

Abstract: Systems and methods are disclosed for communicating via a communications network with a load control system of a respective user environment, receiving information on the load control system via the communications network, displaying graphical user interfaces based on the received information, and controlling and configuring the load control system via graphical user interfaces by communicating via the communications network messages the load control system.

Abstract: In an auto vibrancy mode, a vibrancy value for a lighting load may be automatically determined based on a selected color setting for the lighting load. The automatically determined vibrancy value may also be configured to emit light from the lighting load at or above a target CRI value for the selected color setting. The selected color setting may be a CCT value on the black-body curve or an x-y chromaticity value. If the selected color setting is CCT value on the black-body curve, the automatically determined vibrancy value may be a pre-defined vibrancy value that is configured to emit light from the lighting load at or above the target CRI value for the selected CCT value. If the selected color setting is an x-y chromaticity value, the automatically determined vibrancy value may be based on the distance between the selected x-y chromaticity value and the black-body curve.

Abstract: An apparatus for sensing an obstruction within a tube being cleaned and repetitively advancing and retracting a flexible high pressure fluid cleaning lance within the tube is disclosed. The apparatus monitors drive roller/belt position and actual hose position, compares the belt (expected travel) to hose position (travel) and generates a position difference, or mismatch. If the mismatch is above a predetermined level, the drive motor direction is reversed for a predetermined time interval, and forward operation restored after the predetermined time interval; and the sequence of repeating the reversing and restoring operations is continued until the position difference or mismatch no longer exceeds the predetermined difference threshold.

Abstract: A differential gearing device includes a base gearing device and an actuator. The base gearing device including a first gear connected to a first output of the differential gearing device, a second gear connected to a second output of the differential gearing device, differential gearing connected to each of the first gear and the second gear, and a clutch connected between the first gear and the second gear. The actuator actuates the clutch to change a torque bias ratio between the first gear and the second gear.

Abstract: In a chip-on-array approach, acoustic and electronic modules are separately formed. The acoustic stack is connected to one interposer, and the electronics are connected to another interposer. Different connection processes (e.g., using low temperature bonding for the acoustic stack and higher temperature-based interconnect for the electronics) may be used. This arrangement may allow for different pitches of the transducer elements and the I/O of the electronics by staggering vias in the interposers. The two interposers are then connected to form the chip-on-array.
