Abstract: A method of detecting objects with a night vision system is provided. The night vision system includes a light source and a camera. The method includes activating the light source as a sequence of light pulses wherein each light pulse is increasing in intensity for a predetermined number of pulses to form a pulse train. The camera is activated as a corresponding sequence of detection windows wherein each of the windows corresponds to one of the light pulses for receiving reflected light resulting from the corresponding light pulse. The light pulses and detection windows are configured such that a time delay between each corresponding light pulse and detection window is increasing throughout the pulse train. In another variation, the camera gain is increased throughout the pulse train. In yet another variation, the light pulses have constant amplitude, the camera gain is constant for all pulses, and the number of camera gain windows increases as the delay increases.

Abstract: A night vision system for a vehicle is provided. The system includes an illumination subsystem for illuminating a region proximate the vehicle, a receiver for receiving light reflected off objects in the illuminated region and generating a signal responsive to the received light. A GPS unit is included in operative communication with a GPS network for generating a time signal and vehicle directional data. A controller is programmed to periodically pulse on the illuminating device and the receiver substantially simultaneously as a function of the time signal and the vehicle directional data. In particular, vehicles traveling in opposite directions will have their night vision system activated out-of-phase with each other so that neither night vision system is “blinded” by illumination emitting from the other.

Abstract: A telepresence system for providing users with displays of a remote environment. In certain embodiments, the system includes a plurality of arrays of cameras, with each arrays are situated at varying lengths from the environment. Users navigate the arrays via interface devices. The system interprets the user inputs and selects camera outputs based thereon. Multiple users are able to navigate simultaneously and independently through the environment. In embodiments having overlapping camera views, the system effectuates seamless motion along camera paths by processing the camera outputs corresponding to the views.

The system 10 further includes a thin sheet optical element 16 extending along a first axis 27 receiving light from the infrared light source 14 and reflecting the light generally in a first direction. Finally, the system 10 includes an infrared camera for receiving the light reflected off objects in the environment and generating a video signal responsive to the received light.

Abstract: A bullet, bullet jacket, and method of making the bullet and bullet jacket. The bullet jacket comprises a predominantly copper outer shell and a predominantly zinc lining. The bullet comprises the bullet jacket and a bullet core. The bullet jacket is made by forming a predominantly copper sheet and a predominantly zinc sheet. The two sheets are then adhered to one another by cladding or roll bonding, and shaped such that they can fully encase a bullet core. The bullet is then made by using conventional means to seat and enclose the bullet core within the bullet jacket of the present invention.

Abstract: A telepresence method and system for providing users the ability to navigate through an array of cameras capturing an environment. The array of cameras includes one or more series of cameras, wherein each series of cameras defines a path through the environment and wherein the cameras in each series have a progressively different perspective of the environment. Users interactively navigate through series of cameras, thereby simulating movement along paths.

Abstract: A system and method for determining a distance of an object is provided. The method includes transmitting a light pulse to a polymeric light reflector at a first time. The method further includes reflecting the light pulse from the reflector. The method further includes receiving a portion of the light pulse reflected from an object at a second time. Finally, the method includes determining a distance of the object from the reflector based on a time difference between substantially the first and second times.

Abstract: A system and method for detecting an object is provided. The method includes emitting a light pulse. The method further includes receiving a reflection of the light pulse. The method further includes indicating a presence of the object from the received light pulse. Finally, the method includes adjusting sensitivity of the indicating step based on an elapsed time from the emission.

Abstract: A telepresence system for providing a first user with a first display of an environment and simultaneously and independently providing a second user with a second display of the environment. In certain embodiments, the system includes a plurality of arrays of cameras, with each arrays are situated at varying lengths from the environment. In one embodiment, the cameras situated around the environment are removed after the cameras in the array are have transmitted the camera output to an associated storage node. A first user interface device has first user inputs associated with movement along a first path in the array, and a second user interface device has second user inputs associated with movement along a second path.

Abstract: The present invention relates to networked computer systems, and in particular to a method and system for improved update facilities for software programs installed on a subset of said networked computers. It is based on the concept that updating the supplier nodes and updating the dependent nodes have to be hierarchically separated from each other. The following sequence of steps is performed: selecting a first subgroup (20) comprising at least one dependent computer (24), selecting a second subgroup comprising at least one of the supplier computers (14) for providing the updated version means exclusively to dependent computers (24,26) until a predetermined condition has occurred, loading at least one computer (24) of the first subgroup (20) with an updated version means during continued operation of the unselected plurality of dependent computers (26,28,30) with a former version means.
