Abstract: An adaptive navigation system for airborne, ground and dismount applications. The system performs adaptive fusion of all sensed signals, information sources, and databases that may be available on a single or multiple cooperative platforms to provide optimal Positioning, Navigation, and Timing (PNT) state. To reduce error building over time, the system incorporates the concept of geo-registration fusion into the ANAGDA filter. The architecture of the ANAGDA filter consists of user/application configurable functionalities in hierarchical layers. The sensing layer senses the environment and contains the required databases such as surveyed landmarks, and Digital Terrain Elevation Data/Digital Elevation Model (DTED/DEM). The processing layer has a Smart Sensor Resource Manager which is a performance-based sensor/feature selection module. The measurement abstraction layer isolates the filter from hardware specifics.

Abstract: An improved surgical stapler including a digital counter to facilitate easy accounting of the number of staples consumed during a procedure. The surgical stapler also includes audible feedback including a first audible sound to indicate when an individual staple has been formed and a second audible sound to indicate that the stapler is ready to begin another staple forming process. The surgical stapler is of simple construction that lends itself to low cost production and mass assembly techniques thereby enabling it to be a disposable device.
