Abstract: Techniques control a utility vehicle. Such techniques involve storing electric power in a lithium battery of the utility vehicle. Such techniques further involve operating a motor controller of the utility vehicle in a normal mode in which the motor controller provides electric power from a lithium battery of the utility vehicle to an electric motor of the utility vehicle to turn one or more ground engaging members of the utility vehicle. Such techniques further involve, after operating the motor controller in the normal operating mode, operating the motor controller in a walkaway mode in which the motor controller configures the electric motor to provide braking torque.

Abstract: A lawn mower front wheel positioning system that provides adjustment of lateral positioning of a front wheel of the mower. The front wheel positioning system includes a wheel support arm, a wheel support member, and a wheel positioning arm having an adjustable length. The wheel positioning arm having a proximal end that couples to the wheel support member and a distal end that couples to the wheel support arm. A first end of the wheel support arm couples to the front wheel. A second end of the support arm couples to the support member by way of a support arm wheel pivot that defines a wheel pivot axis. The wheel support arm and the front wheel rotate about the wheel pivot axis responsive to adjustment of the length of the wheel positioning arm.

Abstract: A whole blood separator device has a sleeve. The sleeve has a sleeve body. The sleeve body has an enlarged first proximal end portion and an enlarged second distal end portion and an intermediate cylindrical tube portion connecting the first proximal end portion and the second distal end portion. The sleeve body is configured to fit inside a test tube and receive whole blood which can be separated by centrifugation into a plasma layer in the proximal end portion, a buffy coat layer in the intermediate portion and a red blood cell portion in the distal portion. The whole blood separator device wherein at least the proximal end portion has an open end. Preferably, the distal end portion also has an open end.

Abstract: Methods and systems for ultrasound imaging and beamforming with a matrix array of transducer elements are provided. Receive signals of each transducer array element are amplified. The amplified receive signal of each transducer array element is digitized. A delay and weight are applied on the amplified and digitized receive signals. The amplified, digitized, delayed, and weighted receive signals are summed across all transducer elements of the matrix array to form a dynamically focused receive beam. An application specific integrated circuit (ASIC) that is integrated with the matrix array of transducer elements performs such steps.

Abstract: In a riding mower having a frame, a mower deck supported beneath the frame, a chair on said frame and a source of motive power also supported on said frame and including two hydraulic transaxles depending beneath the frame to each selectively rotate a drive wheel. The frame is supported on forward and rear wheel assemblies with a supporting wheel. The transaxles are supported beneath the frame and pivotally secured thereto by a flange captivating vibration pillows and proximate the driven wheel and an inner pivot rod secured to the frame by apertures in downwardly depending tabs.

Abstract: Techniques involve controlling battery access on a utility vehicle. Such techniques involve monitoring status of input signals from a group comprising: a lithium battery system, a keyed switch, and a charging receptacle, comparing the status of the input signals to timeout settings stored in memory of the motion control system, initiating a timer based on comparison of the input signals to the timeout settings, and disconnecting at least one direct current (DC) path between a lithium battery interface and a power distribution interface of the utility vehicle in response to expiration of the timer. Such techniques further involve, after disconnecting, reconnecting the at least one DC current path between the lithium battery interface and the power distribution interface in response to a change in status of at least one of the input signals. Such techniques may be performed by a motion control system of the utility vehicle.
