Abstract: The invention relates to a method for activating a motion system of a simulator provided for simulating motion and/or acceleration values, wherein at least one acceleration value (1) which is to be simulated is simulated by the motion system being inclined in relation to the earth's vertical, and an additional translatory motion profile (5) of the motion system is determined in order to compensate liar a simulation error (3) until the positioning angle is reached. Activation then takes place in dependence on an inclination profile and the additional translatory motion profile (5).

Abstract: A method for editing a computer-aided design model for developing electronic control units in a design environment, whereby the design model comprises at least one model object with first data. The method begins with the reading of all model objects of the design model and the reading of an allocation list, which assigns a particular globally unique key to each model object. If the first data are available, the reading of the first data from a first memory location follows. Then, assignment of the first data to the model object based on the globally unique key occurs, so that the first data are available during editing of the design model. If the first data are not available, assignment of the globally unique key to the model object occurs, so that the globally unique key is available during tediting of the design model.

Abstract: An audit system and method audits operation of an optimizer system in a mill, for example auditing operation of a cant optimizer which optimizes sawing patterns. The audit system may be completely independent of the optimizer. For example, the audit system may acquire information (e.g., optically) indicative of a geometry of boards downstream from a piece of equipment such as a gangsaw. The audit system may computationally reconstruct a cant from which the boards were sawn, determine an outside dimension indicative of wane, and simulate alternative sawing patterns, determining a theoretical amount of recovery that would have resulted from each and comparing such to actual recovery from the log or cant. Alternative sawing patterns may take into account various wane rules and comparison may take into account current demand and/or prices for dimensional lumber.

Abstract: A safety automation builder that assists in development of compliant safety functions for industrial safety systems is provided. The safety automation builder imports a system drawing or image of a user's manufacturing line, machine, or production area, and guides the user through a workflow that facilitates configuration of safety functions for each hazardous access point. The safety automation builder leverages a library of safety devices and encoded knowledge of industrial safety standards to guide the user toward selection of suitable safety devices for mitigating risks associated with the access points. Once configured, the safety automation builder can export the safety function data to an external verification system for confirmation that the configured safety functions comply with the prescribed industrial safety standards.

Abstract: This invention relates to a method of designing an illumination device, wherein a light source unit is modeled with a set of rays. Therein, each ray is assigned a light power and is further characterized by a light volume, which specifies how “spread out” the light is in area and angle. In this way, a selection of rays with respect to their “density” becomes possible, and an optical system can be optimized for a transmission of those rays providing the most light per volume.

Abstract: A method and system for using Bezier curves in vehicle positioning and electronic horizon applications for providing data to advanced driver assistance systems (ADAS) applications are disclosed. The Bezier curves are obtained from B-splines. The obtained Bezier curves are subdivided in a manner that allows the vehicle positioning application to derive a polyline representation in real time. Using the Bezier and polyline geometry, the vehicle positioning application provides a vehicle position approximation to the ADAS applications. Using the Bezier curves, the electronic horizon application provides curvature, slope, and heading profiles to the ADAS applications.

Abstract: Clock distribution schemes in emulation systems are typically complex and use significant resources. The present disclosure is generally directed to clock distribution to emulation chips using a serial interconnect mesh. A clock distribution tree is overlayed on the emulation chips allocated to a user's circuit design, the tree branching from a root emulation chip using selected serial interconnections and covering each allocated emulation chip. The emulation chips can recover a clock from received serial signals. The delay associated with each interconnection is determined and used by configuration software when creating the distribution tree. To start emulation stepping synchronously, each emulation chip is configured to know its delay from the root emulation chip. A message is sent from the root emulation chip to each branch emulation chip triggering a timer to countdown a time until emulation is to begin, allowing the emulation chips to start stepping in lockstep.

Abstract: Water surface and other effects are efficiently simulated to provide real time or near real time imaging on low-capacity computer graphics computation platforms. Water and other surfaces are modeled using multiple independent layers can be dynamically adjusted in response to real time events. The number of layers used in a given area can be adjusted to reduce computational loading as needed. Different algorithms can be employed on different layers to give different effects. The multiple layer modeling is preferably converted to polygons using an adaptive polygon mesh generator based on camera location and direction in the 3D world to provide automatic level of detailing and generating a minimal number of polygons. The visual effects of water droplets and other coatings on see-through surfaces can be modeled and provided using indirect texturing.

Abstract: A simulation technique that handles accesses to a frame of memory via a proxy object provides improved throughput in simulation environments. The proxy object, if present, processes the access at a head of a linked list of frames. If a check frame is not inserted in the list, the memory frame handles the request directly, but if a check frame is inserted, then the check operation is performed. The check frame can be a synchronization frame that blocks access to a memory frame while the check frame is present, or the check frame may be a breakpoint, watch or exception frame that calls a suitable handling routine. Additional check frames may be chained between the interface and the memory subsystem to handle synchronization, breakpoints, memory watches or other accesses to or information gathering associated with the memory frame.

Abstract: Solar irradiance, the energy from the Sun's electromagnetic radiation, has a wide range of applications from meteorology to agronomy to solar power. Solar irradiance is primarily determined by a location's spatial relationship with the Sun and the atmospheric conditions that impact the transmission of the radiation. The spatial relationship between the Sun and a location on Earth is determined by established astronomical formulas. The impact of atmospheric conditions may be estimated via proxy using pixels from satellite imagery. While satellite-based irradiance estimation has proven effective, availability of the input data can be limited and the resolution is often incapable of capturing local weather phenomena. Brief qualitative descriptions of general atmospheric conditions are widely available from internet weather services at higher granularity than satellite imagery.
