Abstract: A method of estimating a state-of-charge of a battery pack having one or more cells is provided. The method includes obtaining, by a battery controller of the battery pack, data from a device electrically coupled to the battery pack. The data is indicative of a power requirement for the device. The method can further include determining, by the battery controller, a state-of-charge of the battery pack based, at least in part, on the data indicative of the power requirement for the device.

Abstract: A battery pack that includes a housing connectable to and supportable by a tool. The battery pack also includes a controller having a processor and a memory. The controller is connected to one or more sensors which provide data to the controller related to operational characteristics of the battery pack. The controller stores the operational characteristics of the battery pack in the memory. The battery pack also includes a battery pack black box. The controller communicates with the black box using a wired communication bus and transmits the stored operational characteristics of the battery pack to the black box. The battery pack black box is capable of transmitting the stored operational characteristics wirelessly to a device external to the battery pack.

Abstract: A device that includes a controller having a processing unit and a memory. The device includes an enable circuit. The enable circuit prevents the device from operating (e.g., discharging current and/or receiving charging current) until the enable circuit is activated. The enable circuit includes an activation component (e.g., a near-field communication [“NFC”] circuit). The activation component is configured or operable to cause the device to become enabled when the activation component is activated by an external enabling device.

Abstract: The present invention relates generally to a software architecture for simulation of physical entities. The invention provides an object-oriented container based framework architecture for simulator software implementations, methods, and objects in a time domain on a distributed computer network. The invention further provides an interface system and a plug-in definition which allows compartmentalization of participants in the container and easy extensibility of the system. The invention further provides a system and method for streaming video in a container-based architecture.

A hierarchy of life-cycle containers having contained objects is disclosed. An object graph description is used by an assembly engine to construct an executable object graph including the hierarchy of life-cycle containers. Life-cycle containers can be implemented as LRU portable containers for field deployed units.

Abstract: Disclosed is a method for displaying a topology having topological features on a display. The method includes dividing the topological region into tessellations. An object-based database is accessed which comprises geometrical objects representing the topological features with each geometrical object associated with a particular tessellation. The geometrical objects are one of a polygon object, a polyline object and a point object representing the topological features. A tessellation is selected to be displayed. The geometrical objects are fetched which are associated with the tessellations to be displayed. The fetched geometrical objects are drawn on the display.

Abstract: The present invention is a GIS system in which topological information is classified as geometrical objects and uses a region identifier and a geometry attribute to reconstruct each topological feature. The present invention starts from the geometrical objects representing topological features. Each geometrical object has an entry including a region identifier attribute and a geometry attribute defining the geometry of a complete representation of the feature. These geometrical objects are complete in that an entry of the object attribute includes a record for a geometry attribute defining the complete geometry of a complete representation of a topological feature. These complete geometrical objects need not inherit attributes from other objects. The objects are classified as either a polygon object, polyline object, point object or raster object and stored in a respective object-based database.
