A lancing assembly is pivotally coupled to a housing and includes an actuator and a leaf spring carrying a lancet. When the actuator is in its set position, the leaf spring and lancet are in their set position with the leaf spring engaging a catch member of the housing. When the actuator is moved to its actuated position, the leaf spring pivots and deflects against the catch member, thereby storing a drive charge. The leaf spring then releases from the catch member as the stored charge launches the lancet to its lancing position. The leaf spring recharges towards the end of the lancing stroke, which return charge then retracts the lancet back into the housing.

The present invention is directed to a planter with seed meters with accelerator wheel systems. Each accelerator wheel system receives singulated seeds from a respective seed meter and spaces the seeds with respect to each other to correct timing and thus spacing anomalies of seeds being released from seed disks of the seed meters at incorrect seed disk release events and to adjust the velocity of the seeds to correspond to planter travel speed for releasing the seeds to drop straight down onto the field, without a horizontal velocity. Spacing and timing is also improved by reducing delivery variation typically attributable to bounce down a seed tube by instead smoothly rotationally redirecting seeds from a generally downward delivery direction from a seed disk to a generally horizontal delivery direction out of the accelerator wheel system, opposite the tractor and implement travel direction.

The light transmitted and reflected by all-dielectric optically variable pigments varies according to viewing angle. The color travel of an all-dielectric optically variable pigment depends on amplitude changes and wavelength shifts in reflectance peaks of the pigment. The width and center wavelength of reflectance peaks can be controlled by selecting the ratio of thicknesses between high-index and low-index layers in a thin film stack. Reflectance peaks can regenerate or become suppressed and shift with tilt angle, thus providing a wide variety of color trajectories.

A method, medium and implementing processing system are provided in which the presence of workers in a long highway construction zone is monitored and the electronically-controlled posted speed limit is adjusted in accordance with the detected presence of workers in the immediate area. In an example, Radio Frequency Identification (RFID) scanners or readers are strategically placed in a construction or working area. Such RFID reading devices may be embedded, for example, in construction speed limit signs. The displayed speed limit is controlled by the detected proximity of construction workers wearing RFID-embedded clothing, for example, such as safety vests or helmets. The speed limit sign includes logic to display one of many possible speed limit displays based on the nearest, and / or the number of RFID signals detected in a given area. Vehicular traffic is thereby enabled to travel faster through construction zones where no workers are present and, when appropriate, traffic is slowed when workers are present within a given proximity of the RFID reading devices.

The bed of the vehicle utilizes a quick load and unload system that includes either rails or alignment guide posts in a manner that allows the user to quickly change the vehicle's primary function.

A medium of interest is interrogated according to ultrasound elastography imaging. A preliminary elasticity-spatial-map is formed. This map is calibrated against a reference elasticity-spatial-map that comprises an array (232) of different (240) elasticity values. The reference map is formed to be reflective of ultrasonic shear wave imaging of a reference medium. The reference medium is not, nor located at, the medium of interest, and may be homogeneous. Shear waves that are propagating in a medium are tracked by interrogating the medium. From tracking locations on opposite sides of an ablated-tissue border, propagation delay of a shear wave in the medium and of another shear wave are measured. The two shear waves result from respectively different pushes (128) that are separately issued. A processor decides, based on a function of the two delays, that the border crosses between the two locations. The calibrated map is dynamically updated and may include post-ablation border expansion (346) and time-annotated previous stages (344, 348).
