Abstract: Systems and methods are provided for modulating laser treatment on the eye. In use, an eye of a patient is scanned using a laser scanning system to produce a scan result. A mapping of the eye is created based on the scan result. Additionally, a modulated treatment of the eye is created based on the mapping. Further, a laser illumination light beam is delivered to a first location on the eye of the patient in accordance with the modulated treatment.

Abstract: A method for a media environment driven content distribution platform includes obtaining synchronization data and ancillary data pegged to instants in the synchronization data, and communicating the synchronization data and the ancillary data pegged to the instants in the synchronization data such that subsequent alignment of the synchronization data to the content synchronizes the ancillary data pegged to the instants in the synchronization data derived from the content to the content.

Abstract: The subject disclosure relates to a machine apparatus. The machine apparatus may perform work on one or more work pieces. The machine apparatus may be augmented or reconfigured to work on a plurality of different work pieces in specific and unique configurations.

Abstract: There is provided a method for a machine learning based method of analysing drug-like molecules by representing the molecular quantum states of each drug-like molecule as a quantum graph, and then feeding that quantum graph as an input to a machine learning system.

Abstract: A method for efficient plasma etching of surfaces inside three-dimensional structures can include positioning an inner electrode within the chamber cavity; evacuating the chamber cavity; adding a first inert gas to the chamber cavity; regulating the pressure in the chamber; generating a plasma sheath along the inner wall of the chamber cavity; adjusting a positive D.C. bias on the inner electrode to establish an effective plasma sheath voltage; adding a first electronegative gas to the chamber cavity; optionally readjusting the positive D.C. bias on the inner electrode reestablish the effective plasma sheath voltage at the chamber cavity; etching the inner wall of the chamber cavity; and polishing the inner wall to a desired surface roughness.

Abstract: A cutting unit mounting device includes a ball through which a yoke extends laterally. The yoke is attached to the cutting unit, and the ball is pivotably mounted in a ball housing attached to a lift arm. A releasable lock pin engages and secures the ball within the ball housing in a mowing position or a service position. The ball housing has stops to limit the pivoting of the ball and yoke with respect to the ball housing. A releasable lock pin engages notches in the ball to engage and secure the ball in the mowing position or service position with respect to the ball housing.

Abstract: A ball joint assembly for attaching a cutting unit to a yoke includes a two piece ball positioned around the yoke, and a ball housing attached to the end of a lift arm and mounted over the two piece ball and securing the two piece ball to the yoke. The ball housing may have stops limiting angular movement of the two piece ball and the yoke with respect to the ball housing.

Abstract: A cooling enclosure is mounted to the frame of a grass mowing machine adjacent the engine cooling fan of an internal combustion engine. The engine cooling fan draws ambient air across the controllers and batteries in the cooling enclosure. The cooling enclosure includes a one piece molded plastic structure that holds and supports batteries and electronic controllers at positions spaced from its bottom surfaces. One or more removable or hinged panels cover the top of the structure.

Abstract: A grass mowing machine has a frame with an adjustable width toolbar including a center section and left and right outer sections telescoping into the center section. A pair of cutting units are mounted to lift arms pivotably connected to outboard ends of the outer sections of the adjustable width toolbar. A hydraulic lift cylinder is mounted between an inboard end of each lift arm and the adjustable width toolbar at a selected mounting point in the center section. The mounting point of the center section is aligned with a mounting point in one of the outer sections to provide a specified toolbar width suitable for the cutting units.

Abstract: A mechanism for offsetting cutting units for a grass mowing machine includes lift arms that pivot between a first lowered position in which the cutting units are offset to the left of the traction vehicle, a second lowered position in which the cutting units are offset to the right of the traction vehicle, and a raised position intermediate the first and second lowered positions. Each lift arm has a first pivot axis and a second pivot axis parallel to the first pivot axis.

Abstract: A mounting device to connect a rotary cutting deck to a lift arm includes a bracket having a first pivoting connection and a second pivoting connection parallel to the first pivoting connection. The first pivoting connection is connected to the lift arm and the second pivoting connection is connected to the rotary cutting deck. The pair of pivoting connections allow the deck to pitch. The bracket may be channel shaped and may have an opening or slot through which the lift arm extends. Additionally, a T-shaped pivot pin provides a third pivoting connection between the lift arm and bracket, the third pivoting connection being perpendicular to the first and second pivoting connections.

Abstract: A cryogenic vacuum rf feedthrough device comprising: 1) a probe for insertion into a particle beam; 2) a coaxial cable comprising an inner conductor and an outer conductor, a dielectric/insulating layer surrounding the inner conductor, the latter being connected to the probe for the transmission of higher mode rf energy from the probe; and 3) a high thermal conductivity stub attached to the coaxial dielectric about and in thermal contact with the inner conductor which high thermal conductivity stub transmits heat generated in the vicinity of the probe efficiently and radially from the area of the probe and inner conductor all while maintaining useful rf transmission line characteristics between the inner and outer coaxial conductors.

Abstract: A height of cut adjustment system for a reel type grass cutting unit includes adjustment screw mechanisms mounted at each corner of the cutting unit. Linkages between the adjustment screw mechanisms permit driving all of the adjustment screw mechanisms synchronously from a single adjustment point to change the cutting height. The linkages may be worm gear drives or other mechanical linkages.
