摘要： A system for fertilizing a large area. The system may include a fluid bar configured to be towed by a tractor. The fluid bar may include a fluid passageway with at least one aperture and a sensor or meter in communication with the aperture. The aperture may be configured to receive a hose or other attachment distributing fluid to the ground. The system may include a tank, a pump, pump controller and a filter. The pump flow rate and the outlet flow rate may be displayed on monitoring equipment located within a cab of the tractor. The pump controller may be used by the farmer to variably adjust the fluid pressure in each aperture and consequently adjust the flow pressure of fertilizer added to the ground.

摘要： A contact originator is given a choice to enqueue the contact in multiple contact queues, to serve multiple needs or interests of the originator. If the contact reaches the head of the queue for the primary need while the contact is being serviced from a queue for a secondary need, the contact either remains at the head of the primary-need queue until the servicing at the secondary-need queue is completed, or a resource of the primary-need queue is conferenced in with the contact and the resource of the secondary-need queue so that the resources can serve both needs simultaneously.

摘要： An ultrasound transducer array (408) includes at least one transducer element (412) having a first (604) and second (606) portions separated by an acoustical discontinuity (520). The first portion (604) has the desired length to form a half-wave k31 resonance, while the second portion (606) has a resonant length for an undesired very low frequency out-of-band k31 resonance. The thickness of the transducer element (412) is designed for k33 half-resonance. Given the design, the transducer element (412) can operate and provide for both forward-looking (514) and side looking (512) elevation apertures. A method is also disclosed for using the disclosed ultrasound transducer (412) in ultrasound imaging.

摘要： Methods and systems for measuring mechanical property of a vascular wall and a method and system for determining health of a vascular structure are provided wherein local deformation of a vessel wall resulting from physiologic pressures with altered transmural forces is measured. A non-invasive free-hand ultrasound scanning-procedure was performed to apply external force, comparable to the force generated in measuring a subject's blood pressure, to achieve higher strains by equalizing the internal arterial baseline pressure. When the applied pressure matched the internal baseline diastolic pressure, strain and strain rate increased by a factor of 10 over a cardiac cycle. Radial arterial strain was assessed in the vessel wall over the entire deformation procedure using a phase-sensitive, two-dimensional speckle-tracking algorithm. An elastic modulus reconstruction procedure was developed to estimate the non-linear elastic properties of the vascular wall.
