Abstract: A pixel circuit acts as a sensing element in a sensing device. The pixel circuit includes a sensing electrode, a first gate electrically connected to the sensing electrode, a second gate in electrical communication with the first gate, and a readout device that is electrically connected to the second gate. An input voltage applied to the sensing electrode is amplified between the first gate and the second gate, the amplification being measured as an output signal from the readout device to perform a sensing operation. For example, the output signal may be relatable to pH, analyte measurements, or other properties of sample liquids analyzed by the sensing device. A sensing device may include multiple pixels disposed on a substrate, each pixel including said pixel circuit. Driver circuits controlled by control electronics are configured to generate signals that selectively address the pixels and to read out voltages at the sensing electrodes.

Abstract: A system for providing print device dynamic status indicator feedback includes a print device, and a status indicator feedback unit. The print device includes a print engine and one or more status monitors. The status indicator feedback unit includes a display device, a light emitting module, a processor in communication with the light emitting module, and a computer-readable medium containing programming instructions. The system may receive information corresponding to one or more current machine states of the print device from the one or more status monitors of the print device, determine a priority level associated with each of the one or more current machine states, identify a machine state associated with a highest priority level, identify a dynamic feedback pattern associated with the identified machine state. The dynamic feedback pattern includes a visual pattern. The system may and instruct the light emitting module to emit the visual pattern.

Abstract: A cargo body of a refuse truck includes a support frame and a bed having a storage volume supported by the support frame. A container handling apparatus includes a primary lift arm for lifting a container lift platform using an actuation system. The primary lift arm is pivotally connected to the support frame at a pivot location between the support frame and the primary lift arm. The actuation system includes a hydraulic cylinder including an actuation rod that is used to move the primary lift arm between raised and lowered positions. A clevis member is connected at an end of the actuation rod. The clevis member has an arm link connection portion that pivotally connects to an arm linkage at a pivot location between the clevis member and the arm linkage and a traveler portion including a traveler member that moves along a guide track as the actuation rod is extended and retracted. The pivot location between the clevis member and the arm linkage is offset from the traveler member.

Abstract: Methods and systems for assembling and using a hydraulic pallet jack box actuation system for a refuse truck are disclosed. The system includes an assembly that supports a pallet jack box sized and configured to contain at least a portion of a pallet jack. The assembly includes a top portion including a linkage connection portion that connects to a cross member of a truck frame, a bottom portion that includes a pallet box support member configured to be raised and lowered between the truck frame and a ground, and a hydraulic cylinder disposed between and connecting the top portion and the bottom portion. The hydraulic cylinder includes a top cylinder portion and a bottom portion configured to extend between an extended position to place the assembly in an extended configuration closer to the ground and a retracted position to place the assembly in a retracted configuration.
