A servo motor controller capable of eliminating inconvenience that the position of a shaft or the like of a servo motor is detected or set erroneously due to influence of noise or the like is provided. A servo motor controller that detects Z-phase signals of an incremental-type encoder that detects rotation of a servo motor to perform driving control of the servo motor includes: a position detection unit that detects a reference position of a rotating shaft of the servo motor on the basis of the Z-phase signal of the encoder; a signal interval detection unit that measures intervals of a plurality of detected Z-phase signals; and an abnormality determination unit that determines that the Z-phase signal is abnormal when the interval measured by the signal interval detection unit is equal to or larger than a prescribed threshold.

An example inspection robot may include a drive module structured to engage a top tube of a vertically arranged layer of tubes, at least one telescoping pole, and a lowering mechanism operationally coupled to the at least one telescoping pole and structured to selectively extend or retract the at least one telescoping pole, thereby providing a selected vertical position of a sensor carriage assembly. The sensor carriage assembly may be coupled to the at least one telescoping pole, and structured to accept at least one of a plurality of sensors.

A solar tracking mounting system is provided. The tracking system has an anchor comprising a pile and a riser bracket fastened to the top thereof, wherein the riser bracket is configured to provide adjustable mounting points, a chord assembly coupled to with the riser brackets, wherein the chord assembly is configured to pivotability tilt, a kicker connected to the anchor assembly, wherein the kicker is configured to connect the chord assembly to the pile, a vertical actuator connected to the kicker and the chord assembly, wherein the vertical actuator is a rack and pinion linear actuator configured to amplify a torque received from a motor and pivotably tilt to the chord assembly to a desired angle while tracking a direction of a light source, and a driveshaft connected to the motor and the vertical actuator. A jack screw may also be provided therein for actuation.

A fluid delivery system including an articulated fluid delivery unit (FDU) comprising, in preferred embodiments, first and second boom sections concatenated in articulated fashion to a turret. A stinger assembly is provided at a distal end of the FDU. The stinger assembly includes a fluid connection adapter for connection to a mating fluid connection housing assembly provided on a wellhead. Independent control of rotation at each of multiple axes on the FDU allows an operator to establish a measured directional bearing at each axis, such that a set of directional bearings values defines the FDU's current spatial position. In preferred embodiments, the FDU may learn a desired spatial position by storing the set of directional bearings values corresponding to that spatial position. The FDU may then return to that stored spatial position robotically when instructed to recall and take up again the corresponding set of directional bearings values.

A linear electrical machine comprising a frame with a level reference plane and an array of electromagnets, connected to the frame to form a drive plane at a predetermined height relative to the reference plane. The array of electromagnets being arranged so that a series of electromagnets of the array of electromagnets define at least one drive line within the drive plane, and each of the electromagnets being coupled to an alternating current power source energizing each electromagnet. At least one reaction platen of paramagnetic, diamagnetic, or non-magnetic conductive material disposed to cooperate with the electromagnets of the array of electromagnets so that excitation of the electromagnets with alternating current generates levitation and propulsion forces against the reaction platen that controllably levitate and propel the reaction platen along at least one drive line, in a controlled attitude relative to the drive plane.

A dual drive pressing apparatus for plural pressing heads is disclosed. The dual drive pressing apparatus includes a platform, a first rotation plate, a second rotation plate, a return set and a switch set. While the first rotation plate is driven by a first driving force, the first rotation plate rotates with the second rotation plate to a selectively specific angle relative to the platform, and the set of pressing columns is selectively aligned with a corresponding pressing head. While a second driving force is provided by the switch set to resist the resilience of the return set and push against the end of the supporting cylinder to move towards the second surface, the supporting cylinder of the second rotation plate drives the fourth surface separated from the first rotation plate, and the set of pressing columns on the third surface pushes the corresponding pressing head set.

An inspection apparatus and methods for inspecting horizontal tubes in an industrial environment are disclosed. The apparatus can include a drive module including a pair of wheels to engage a top tube of a vertically arranged layer of tubes, a telescoping pole, a sensor carriage assembly coupled to the telescoping pole, and a lowering mechanism operationally coupled to the telescoping pole to selectively extend or retract the telescoping pole providing a selected vertical position of the sensor carriage assembly.

In a method and device for the cyclic digital transmission of a position value of a moving object with inertial mass, the value range of the transmitted position value is restricted such that no complete rotation or, in the case of a linear motion, other complete period caused by mechanical conditions may be mapped, and the actual position is formed by detecting value-range exceedances in an evaluation unit.
