Abstract: A tipper assembly includes a base configured to couple to a tailgate of the refuse vehicle and an actuator assembly comprising an actuator and a transmission device. The actuator may be coupled to the transmission device and may be configured to provide an input to the transmission device. The transmission device may be configured to reduce a speed of the input. The tipper assembly further includes an arm extending from and pivotally coupled to at least one of the actuator assembly or the base and an implement coupled to the arm. The implement may be configured to engage with a refuse container and facilitate the dumping of contents within the refuse container into an opening in the tailgate.

Abstract: A geodetic surveying instrument to move a measurement light beam into a desired measurement direction in space, comprising at least one movement axis which is motorized, providing a positioning of the measurement direction of the geodetic surveying instrument, and an instrument-encoder at the movement axis configured for deriving the measurement direction as a measurement value of the geodetic surveying instrument. The geodetic surveying instrument comprises a transmission link of the movement axis of the geodetic surveying instrument to a motor axis of a stepper motor, which transmission link is configured with a gear reduction and a slipping clutch arrangement, and wherein the stepper motor comprises a rotational motor-encoder on its motor-axis and is driven by a motor controller that provides a field oriented control of phase currents of the stepper motor, which field orientation is derived based on the rotational motor-encoder.

Abstract: Method for determining an operational parameter for an imaging device for imaging at least one part of a build plane, in particular for a determination device for determining at least one parameter of an energy beam for an apparatus for additively manufacturing three-dimensional objects, comprising the steps: determining at least one spot parameter that relates to an extension of a spot, in particular a spot of an energy beam, in a determination plane; determining a difference between the determined spot parameter and a nominal spot parameter; determining an imaging parameter of the imaging device based on the determined difference adjusting the imaging parameter based on the determined difference.

Abstract: Method for calibrating at least one apparatus (1) for additively manufacturing three-dimensional objects by means of successive layerwise selective irradiation and consolidation of layers of a build material which can be consolidated by means of an energy beam that can be generated via an irradiation element of an irradiation device (7) of the apparatus (1), wherein a determination unit (2) is provided for determining at least one parameter of radiation (3) inside a process chamber (5), wherein a calibration beam source (4) is arranged or generated inside the process chamber (5) of the apparatus (1), in particular in a build plane (9) or a region above the build plane (9), wherein at least one parameter, in particular the intensity, of radiation (3) emitted by the calibration beam source (4) is determined via the determination unit (2).

Abstract: System and method for automatically controlling a media receiver by instructing the media receiver to use a particular receiver connection and to play a selected media unit using one of a plurality of play modes according to characteristics of the media unit. Media units may be encoded using any of a variety of encoding formats. The media management system may interface with a media receiver to select media receiver connections in accordance with the media type of the media unit. The media management system may also interface with the media receiver to set media receiver settings for playing the selected media unit according to the media receiver settings selected for a play mode corresponding to the characteristics of the selected media unit.

Abstract: A percussion cymbal instrument is muted by using a dampening layer to reduce the sound and acoustic vibrations when struck. In a preferred embodiment, the muting system is comprised of a layer of flexible plastic adhered to a cymbal surface. When the cymbal is struck, the muting system dissipates the normal vibrations of the cymbal without hampering the natural look, feel, playability, or natural swinging motion of the cymbal.

Abstract: A ring-shaped percussion transducer for converting a striking impact into a representative electrical pulse triggering signal is suitable for mounting on the center axis of a percussion instrument. In a preferred embodiment, the transducer is formed of a piezo electric material of ring shape; protected on the top and bottom by thinner ring shaped washers; enclosed in a protective coating and mounted along the center axis of a percussion device which when struck transmits vibrations to the percussion transducer. The percussion transducer is connected to conventional downstream electronics so as to produce a sound responsive to the striking impact.
