Abstract: A control system for a work implement of a machine having a frame is provided. The control system includes a pair of lift cylinders operatively coupled to the work implement and configured to raise or lower the work implement with respect to the frame. Each of the lift cylinders has a rod end and a cap end. The control system includes a first cross-over line configured to fluidly communicate the rod ends to each other and a second cross-over line configured to fluidly communicate the cap ends to each other. The control system includes a cross-over valve disposed in one of the first and second cross-over lines and configured to regulate a flow of hydraulic fluid therethrough. The control system further includes a controller communicably coupled to the cross-over valve and configured to at least partially close the cross-over valve during a dump cycle of the work implement.

Abstract: An eyewear system is provided with adjustable nose pads. The nose pads are adjustable by being slidably mounted onto a portion of the nose bridge. This adjustability feature provides for wearer-selected pantoscopic angle adjustment, as well as wearer-selected fit for a particular nose and face shape. The eyewear may include plano or corrective lenses and other features of eyewear including polarized, tinted, and/or other types of lenses and lens-related features.

Abstract: Embodiments of the present invention include a lens configured to adapt to varying light conditions. The lens comprises a first layer made of a transparent thermoplastic material and a second layer made of a transparent thermoplastic material. The lens also includes a polarized film and a photochromatic film that adjusts to vary the amount of light that is transmitted through the film in response to the amount of ultraviolet radiation received by the film. The lens is thermoformed to have a selected radius of curvature. Embodiments of the lens disclosed herein are adapted for use with a frame that is configured to receive the lens and position the lens proximate a user's face and eyes.

Abstract: Eyewear includes a left temple and a right temple. Each of the temples has a cavity sized to receive an audio device such as a BlueTooth transceiver configured to communicate wirelessly with a remote device like a cell phone or a digital sound device. The BlueTooth transceiver may be placed in the cavity of either temple with the other temple cavity covered with a cover plate. An earphone may be connected to the BlueTooth transceiver through a receptacle. The earphone delivers the audible sound to the user's ear. The receptacle of the BlueTooth transceiver to which the earphone connects is also configured to receive the connector from a charger to charge a rechargeable battery in the BlueTooth transceiver. The eyewear may also be configured with cover plates over the cavity in both of the temples or with an audio device in both cavities to provide audible signals to both ears of the user.

Abstract: An eyewear device includes a frame having two elongate extensions rotatably attached to the frame and movable between a deployed position and a stored position. The frame has two lens receiving portions with multiple lens units insertable in the lens receiving portion some through the front surface and some through the rear surface. The lens units have different eye glass lenses held therein. The elongate extensions include at least one head grip that is movable between two positions in which the head grip extends away from the stem, extensions, ears or temples different distances. A retainer is provided to hold the eyewear to the head; and a leash is provided to secure the eyewear to the clothing. The lens receiving portions have ridges that are configured to interact with grooves in the lens units to hold them in the frame. including a peripheral encasing. The lens units may have a nose piece with a nose pad configured to be removable and to adjust the distance of the nose pad from a support surface.

Abstract: A computer system which utilizes processor boards including a first level cache system integrated with the microprocessor, a second level external cache system and a third level external cache system. The second level cache system is a conventional, high speed, SRAM-based, writeback cache system. The third level cache system is a large, writethrough cache system developed using conventional DRAMs as used in the main memory subsystem of the computer system. The three cache systems are arranged between the CPU and the host bus in a serial fashion. Because of the large size of the third level cache, a high hit rate is developed so that operations are not executed on the host bus but are completed locally on the processor board, reducing the use of the host bus by an individual processor board. This allows additional processor boards to be installed in the computer system without saturating the host bus. The third level cache system is organized as a writethrough cache.
