Abstract: Embodiments include a tire tread having a plurality of tread elements and a plurality of lateral discontinuities arranged along the tread width and tread length, each of the plurality of tread elements being spaced apart by one of the plurality of lateral discontinuities. The tread width is divided into a plurality of regions, the plurality of regions including: (1) a pair of outermost regions, each outermost region being arranged closest to one of the pair of opposing lateral sides of the tread, and (2) at least one centermost region is arranged closest to the longitudinal centerline of the tread. Each of the lateral discontinuities have a thickness, where the thickness of one or more of the lateral discontinuities arranged in each of the outermost regions is smaller than the thickness of one or more of the lateral discontinuities arranged in the centermost region.

Abstract: In particular embodiments, a tire tread includes one or more lateral sipes (26s) arranged within the tread (20). As each such lateral sipe (26s) extends outward from within the tread thickness (T20) and towards the outer, ground-engaging side (22) of the tread (20), the lateral sipe (26s) is inclined towards the intended direction (R) of tire rotation. The lateral sipe (26s) also has a width (W26) (thickness) configured to, at an unworn stage, close along at least a portion of the sipe depth during operation of a loaded tire, and being configured to, at a worn stage, remain open during operation of the loaded tire. The lateral sipe (26s) has a width-to-height ratio associating the sipe width (W26) to the sipe height, the width-to-height ratio equaling 1:10 to 1:40. Providing a plurality of these lateral sipes (26s) may result in improved consistency of tread wear performance over the life of the tread (20).

Abstract: The invention includes a tire tread having one or more lateral discontinuities (26), each discontinuity extending into the tread thickness along a non-linear path. The lateral discontinuity extends from a first terminal end (40) to a second terminal end (42), the first terminal end being located closest to an outer, ground-engaging side relative to the second terminal end. The non-linear path can be described as extending from a first portion (A1, A2, A3), to an intermediate portion (B1), and then to a third portion (C1) when extending towards the second terminal end. The first portion has a low average inclination angle, the intermediate portion has a negative average inclination angle, and the third portion has a positive average inclination angle, each angle being measured relative to the depthwise direction of the tread. A positive angle is angled in the direction of intended tire rotation (R) as the tread thickness extends outward towards the outer, ground-engaging side.

Abstract: A system and method for automatically generating a second graphical program based on a first graphical program. The first graphical program may be associated with a first programming development environment. For example, a user may have interactively created the first graphical program from within the first programming development environment, e.g., by using an editor to place various nodes on a block diagram, such that the nodes visually indicate functionality of the first graphical program. The method may operate to automatically, i.e., automatically, generate a second graphical program based on the first graphical program, such that the second graphical program is associated with a second programming development environment. The method may generate the second graphical program automatically, without relying on user input, or may prompt for user input to determine various options to use in generating the second graphical program.

Abstract: System and method for creating and executing a graphical program. A first plurality of graphical program elements (GPEs) having a first model of computation (MoC), e.g., homogenous dataflow, are assembled in a graphical program in response to first input. A structure, including an interior portion, is displayed in the graphical program, indicating use of a second MoC, e.g., multi-rate dataflow, for GPEs within the interior portion. A second plurality of GPEs having the second MoC are assembled within the interior portion of the structure in response to second input. The second plurality of GPEs are converted into a new third plurality of GPEs having the first MoC, e.g., by parsing the second plurality of GPEs to determine multiple primitives according to the second MoC, determining the third plurality of GPEs based on the primitives, and assembling the third plurality of GPEs in the graphical program.

Abstract: A PID control system and method which maintains continuity of the control output in spite of changes in controller parameters. The controller parameters include a proportional gain, an integral gain, a derivative gain, and a manual/automatic mode parameter. The control output at the time of a parameter change is set equal to the previous controller output, and the integrated error is set to a value consistent with the previous controller output according to a PID controller equation. This value for the integrated error serves to ensure the sustained continuity of the control output after the controller parameter change. Alternatively, the control output at the time of a parameter change is set equal to a first value continuous with respect to one or more previous control output values, and the integrated error is set to a value consistent with the first value according to the PID controller equation. Furthermore, the system and method employs integrator anti-windup. If the control output saturates, i.e.
