  • Publication number: 20240076143
    Abstract: An end of arm tool (EOAT) assembly can include a tool base subassembly having a tool base attachment surface as well as a first and second mechanized tool subassembly, each being movably attached to the tool base subassembly along the tool base attachment surface. The mechanized tool subassemblies include an elongated body oriented orthogonally relative to the tool base attachment surface, and a holding member attached to its respective elongated body. The holding members can have an engaged position to pass beneath an object to assist with lifting of the object and a disengaged position that does not contribute to lifting of the object. Movement of the first and second mechanized tool assemblies along the tool base attachment surface can provide for opening and partially closing of a gap there between to laterally provide space for engaging with the object followed by squeezing the object for lifting.

  • Patent number: 10768320
    Abstract: A system of the present disclosure is capable of detecting, imaging and measuring both neutrons and gamma rays. The system may be portable and/or field deployable. The system may include two or more detector layer cases and a digital processing unit case. The system has a plurality of parallel plates each containing a plurality of detectors. The plates may have non-PSD organic scintillation detectors, scintillation detectors having pulse-shape discrimination (PSD) properties, and inorganic scintillation detectors. A first plate and a second plate are housed within detector layer cases. The scintillation detectors are used in connection to detect, image and measure neutrons and/or gamma rays.

  • Patent number: 8437149
    Abstract: A power supply produces one or more conditioned and scaled output voltages with low noise. The power supply has various components to produce a plurality of higher output voltages from a plurality of taps of a multiplier or multiple isolated outputs. Components include an internal reference voltage circuit or an external voltage that generates a reference voltage and a sine wave power oscillator circuit and resonant circuit that generates an alternating current and voltage. The power supply has a controlled current source circuit connected to the sine wave power oscillator circuit for regulating the power level to the sine wave power oscillator. A control amplifier circuit controls the current level to the controlled current source circuit based on the error between the sampled output and the reference voltage. The resonant transform connected to the sine wave power oscillator circuit generates one or more scaled output voltages on one or more secondary windings.
