  • Patent number: 11685620
    Abstract: According to examples, an apparatus may include a guide frame, a standard position pawl movably attached to the guide frame, the standard position pawl to engage a standard pawl detent. The apparatus may also include a custom position pawl movably engaged with the guide frame, the custom position pawl to engage custom pawl teeth of a rack. The apparatus may further include a switch in movable engagement with the guide frame, the switch being movable between a first position at which the custom position pawl is maintained at a disengaged position with respect to the custom pawl teeth of the rack and a second position at which the custom position pawl is free to move between the disengaged position and an engaged position with respect to the custom pawl teeth of the rack.

  • Publication number: 20230063445
    Abstract: A rotation base has a base circular structure. A display backing has a backing circular structure. The backing circular structure is rotatably attached to the base circular structure to permit the display backing to rotate between landscape and portrait orientations relative to the rotation base. One of the base and backing circular structures defines a slot. The other of the base and backing circular structures defines a tab rotatably disposed within the slot.

  • Publication number: 20230021732
    Abstract: Examples of the present disclosure are directed toward a control panel display with rotatable mount. An example apparatus includes a control panel mount including a first surface to receive a control panel display and a second surface opposite the first surface. The apparatus further includes a rotatable mount including a first surface and a second surface opposite the first surface. A first hinge mechanism which is rotatable about a first axis may allow the rotatable mount to move between a first operational position in which the rotatable mount is disposed in contiguous contact with a top cover of the apparatus and a second operational position in which the control panel display is disposed within a recessed portion of the top cover. A second hinge mechanism may be rotatable about a second axis orthogonal to the first axis to change a display angle of the control panel display.

  • Publication number: 20210267371
    Abstract: According to examples, an apparatus may include a guide system including a first gear having teeth to engage with a first set of teeth, a second gear having teeth to engage with a second set of teeth, the first gear and the second gear to rotate in concert with respect to each other, and a first glide mechanism to slidably contact a first channel. In addition, the apparatus may include a panel to employ the guide system to be slidably mounted to a base structure, wherein the first gear and the second gear are to impede rotation of the panel about a first axis and the first glide mechanism is to impede rotation of the panel about a second axis.

  • Publication number: 20210112170
    Abstract: A modular scanner sub-assembly (SSA) is provided for use with scanners and multi-functional devices (e.g., multi-function printers). The SSA includes a tub and a flatbed imaging surface that is attached onto a top end of the tub. The modular SSA includes multiple scanner components that are operatively assembled within the tub to enable scanner functionality when the scanner or multifunction device is made operative.

  • Patent number: 8474254
    Abstract: A system and method for performing a floating function in an earthmoving implement of an earthmoving machine without physically connecting chambers within a hydraulic actuator that is adapted to raise and lower the earthmoving implement. The system includes a device for delivering a pressurized fluid to and receiving pressurized fluid from the actuator, a valve for compensating for differences in volume between chambers of the actuator, and an electronic control circuit that includes electronic sensors for sensing the pressures in the chambers of the actuator, and a controller for receiving outputs of the sensors. The controller calculates an amount of the pressurized fluid that, when delivered to or received from the actuator, achieves a substantially constant pressures in the chambers of the actuator and enables the earthmoving implement to float regardless of motion of the actuator.

  • Patent number: 8453441
    Abstract: A system and method for controlling the movement of an implement of an earthmoving machine. The system includes a hydraulic actuator adapted to move the implement. A variable displacement pump is coupled to the actuator for delivering a pressurized fluid to and receiving pressurized fluid from chambers within the actuator. A sensor generates an output based on the position of the actuator's piston or piston rod, and a controller controls the displacement of the variable displacement pump in response to the output of the sensor by executing an algorithm to reduce the flow rate of the fluid to and from the actuator's chambers and thereby reduce the velocity of the piston as it approaches an end of a piston stroke thereof and prevent the piston from impacting the actuator at the end of the piston stroke.

  • Patent number: 8191290
    Abstract: A displacement-controlled hydraulic system for installation on a multi-function machine, and multi-function machines equipped with the hydraulic system and having devices for propelling the machine, at least a first implement, and multiple actuators that perform multiple functions of the machine. The multiple actuators include first actuators that control the first implement and second actuators that control the propelling devices. The hydraulic system comprises multiple pumps for controlling the first actuators and optionally the second actuators, and valves that enable at least one of the pumps to sequentially control two of the multiple actuators and a corresponding two functions of the multiple functions performed thereby. None of the pumps sequentially controls the second actuators in combination with any of the first actuators.
