An improved method for determining an initial flat spot magnitude on a tire that has been resting for a period of time on a substantially flat surface uses regression analysis. In accordance with the method, values of a tire flat spot magnitude for a particular type of tire are determined at a number of measurement intervals by a uniformity machine that spins the tire. An equation having at least two exponentially decaying terms is then determined that corresponds to the measured data points. Regression analysis is then used to determine an estimate for an initial flat spot magnitude. The method can be used to evaluate the effectiveness of different tire designs with respect to flat spot recovery rates.

The herein described Adaptive Ergonomic Positioning device (“AEPD”) relates generally to the field of surgery and other medical or healthcare procedures. The AEPD can be adapted for use with most standard surgical tables and surgical chairs where the patient must be positioned prone during a particular procedure. The AEPD may also be used for certain procedures where the patient may be positioned supine. The AEPD support assemblies are highly adjustable and deliver improved ergonomics for both patients and providers. Patients of different morphology can be comfortably positioned in prone with their head and neck in a neutral position, and shoulders in a forward flexed, slightly internally rotated position. The AEPD can be adjusted to accommodate patients with neck and shoulder mobility restrictions, without any effect on provider accessibility to the surgical or treatment site.

A ladder assembly for a work vehicle comprises a deck affixed horizontally just below an entry door of the cab. A yoke is pivotally joined to a support member of the deck for rotation about a vertical axis below the deck surface. The yoke has a pair of arms pivotally joined to an upper end of a ladder structure for allowing rotation of the ladder about a horizontal axis. A turnbuckle is coupled between the support structure of the deck and one stringer of the ladder while a mechanical actuator is operatively coupled to the ladder's other stringer and to an arm of the yoke to which the other stringer is attached. Operation of the mechanical actuator moves the ladder reciprocally between a use position and stowed position where the stowed position is parallel to and immediately below the deck.

A biosensor system comprises a capillary substrate, conductive electrode, and a plurality of nanoparticles having an enzyme deposited thereon formed in a cavity at one end of the capillary substrate. The substrate may have an optional reinforcing layer (which may be conductive or non-conductive) and optional insulating layer thereon. A cannula having an optional conductive layer, insulating layer, and reference electrode may also form part of the system.

The present invention relates to compounds of formula (I): wherein; R1 represents hydrogen or C1-3alkyl; n is an integer having a value of 1 to 5; X represents O or NH; Y represents C or N; or a pharmaceutically acceptable salt thereof, have been shown to be inducers of human interferon and may possess an improved profile with respect to known inducers of human interferon, for example enhanced potency. The compounds of the invention may therefore be useful in the treatment of various disorders, in particular the treatment of infectious diseases, cancer, allergic diseases and other inflammatory conditions, and their use as vaccine adjuvants.

Curved lenses configured to decode three dimensional content and method of fabricating the same. The lenses comprise a polyvinylalcohol polarizer film or similar type of material laminated with triacetate or similar type material on one or both sides, wherein the polarizer film has a polarizing efficiency equal to or exceeding 99% and a transmittance percentage equal to or exceeding 35% and a retarder film (e.g., norbornene copolymer resin) laminated on a front surface of the polyvinylalcohol polarizer film laminated with triacetate and aligned to produce a desired circular polarization responsive to specified retardation wavelengths. Thermoforming and press polishing techniques may be used to fabricate/curve the blanks into lenses. The lenses (optical elements) may be used in an injection molding process to add thickness.

In certain embodiments, a method for estrus detection includes storing location information associated with a dairy livestock. The stored location information includes a coordinate location of the dairy livestock within a free stall pen at each of a plurality of times during a time period. The method further includes determining, based on at least a portion of the stored location information, one or more movement parameters associated with the dairy livestock. The method further includes determining, based on one or more movement parameters associated with the dairy livestock, whether the dairy livestock is likely to be in estrus.

In certain embodiments, a method for milking stall assignment includes storing first location information associated with a dairy livestock, the first location information comprising a coordinate location of the dairy livestock within a milking parlor at a first time. The method further includes comparing the stored first location information associated with the dairy livestock with an area associated with each of a plurality of milking stalls of the milking parlor to identify a milking stall in which the dairy cow is located at the first time and assigning the dairy livestock to the milking stall in which the dairy cow is located at the first time such that data associated with milking of the dairy livestock may be associated with the dairy cow.

A robotic mower boundary coverage system includes a vehicle control unit on the robotic mower commanding a traction drive system to drive the robotic mower at a specified yaw angle with respect to a boundary wire, and a boundary sensor on the robotic mower signaling the distance between the boundary wire and the vehicle control unit. The vehicle control unit alternates commands to direct the traction drive system toward and away from the boundary wire based on the distance of the robotic mower to the boundary wire.
