Abstract: Example embodiments provide methods, mediums, and systems for making and evaluating changes to a model. According to example embodiments, checkpoints may be created as a user changes components in the model. The checkpoints may store changed components in the model that have been changed since a previous checkpoint, and a reference (e.g., a pointer) to the previous checkpoint. A user may freely create new checkpoints, revert to previous checkpoints, and select a checkpointed version of the model to be used as an official working version of the model. Upon activating an existing checkpoint, parametric relationships in the model assembly may be automatically updated in order to make components in the model consistent with each other. Thus, the user can readily change the model and evaluate variations of a design, while at the same time saving storage space by avoiding the need to repeatedly save different versions of the model.

Abstract: A service satellite for providing station keeping services to a host satellite is disclosed. The service satellite may have a body, and a gripping mechanism attached to the body. The gripping mechanism may be adapted to attach to an interface ring extending from an external surface of the host satellite to form an interconnection between the host satellite and the service satellite through the externally extending interface ring. Attaching the gripping mechanism to the interface ring may form an interconnected unit having a combined center of mass. The service satellite may have at least two thrusters and at least one controller. The at least one controller may maintain the interconnected unit in a substantially stationary orbit by selectively orienting the two thrusters such that the thrust vectors from the two thrusters avoid passing through the combined center of mass, and are each offset from the combined center of mass.

The gripping mechanism is adapted to attach to an interface ring extending from an external surface of the host satellite to form an interconnection between the host satellite and the service satellite through the externally extending interface ring.

The at least one controller maintains the interconnected unit in a substantially stationary orbit by selectively orienting the two thrusters such that the thrust vectors from the two thrusters do not pass through the combined center of mass, and are each offset from the combined center of mass.

Abstract: The present invention relates to a service satellite having a body, a controller and a docking unit. The docking unit includes at least two foldable, adjustable gripping arms pivotally mounted on the satellite body, each gripping arm being pivotable relative to the satellite body, and a gripping end at each free end of the gripping arms, wherein the gripping ends are adapted and configured to capture and grip a target portion of an orbiting satellite. Each gripping arm is controllable independently by the controller, which coordinates the motion of the arms.

Abstract: Virtual sensors may be provided to accept outputs of physical sensors as inputs in a model of a system that represents a product. The outputs of the virtual sensors are calculated from physical sensor outputs. In particular, the virtual sensors are calculated by exploiting information and analysis provided in a computer aided design (CAD) environment, including a CAD model and CADs simulation engine.

Abstract: An energy generator system for converting mechanical energy from a workout or otherwise physical environment to electricity. The energy generator is integrated within workout machines for converting the kinetic energy or mechanical energy to electricity. At least one battery or electricity storage device is provided wherein the electricity is stored or appointed for consumption. As the exercise equipment is being used the kinetic or mechanical energy given off is converted to electrical energy by way of the generator, which transfers the electricity to the battery wherein it is stored or transferred for direct use.

Abstract: A flexible object function is for use in conjunction with, or as an element of, a CAD/CAM software application. The flexible object enables the CAD/CAM application to represent an object that can experience variations in its geometry and logical properties for different design occurrences, while maintaining consistent common properties in all of the occurrences. The variations can be driven by the assembly context, or interacting relationships of the specific occurrence with other components or objects.
