  • Patent number: 6976916
    Abstract: An ergonomic and weatherproof hand-held electronic device 10. The device 10 includes a housing 12 which surrounds internal electronics. An input 28 and a display screen 32 are mounted on the housing 12. The housing 12 is has a narrow width such that, when held in a hand, the thumb of that same hand may extend fully across the input 28 for full access. The display screen 32 is mounted vertically below the input 28 such that the device may be more stable and more easily grasped. The device includes two cylindrical cavities 48 to receive batteries 42. The cavities 48 are located at the rear vertical edges of the housing such that the rear of the housing 12 is relatively rounded and thus easier to grasp. The battery cavities open to the exterior of the housing. A battery cover 54 is mounted to the housing and seals the cavities 48. A contact for each cavity 48 is located on the cover, and a bus bar extends between the contacts to complete the circuit between the batteries 42.

  • Patent number: 6975940
    Abstract: Devices, systems, functional data and methods are provided for an improved route generation in navigational enabled devices. In generating the route, the available locations are inspected repetitively and locations adjacent to a last selected location are inserted into a first data structure such that the first location of the first data structure is always a least cost location associated with all adjacent locations comprising the first data structure. The first location is then optionally inserted into a second data structure. The generated route includes the current location, one or more first locations, and the destination.

  • Patent number: 6970795
    Abstract: A navigation device and a method of calibrating the same are provided. The device includes a barometric pressure sensor and a GPS receiver. A processor calculates barometric and GPS derived altitudes and, based on a difference therebetween, corrects barometer altitude readings that would otherwise include drift errors. The processor uses a filter, such as a state feedback loop, to determine correction factors. The state feedback loop is adjustable to operate with different time constants. An error drift model is empirically determined and used to set the time constant. The time constant may be adjusted during operation based on a relation between the barometer correction quantity and an uncertainty in the vertical component of the GPS derived altitude. The method includes updating and recalibrating an atmospheric pressure model used to derive altitudes from the output of the barometric pressure sensor.

  • Patent number: 6967616
    Abstract: An improved system and methods for correlating an interrogation-based air traffic surveillance intruder, such as an Traffic alert and Collision Avoidance System (TCAS) intruder, and a GPS-based air traffic surveillance target, such as an Automatic Dependent Surveillance Broadcast (ADS-B) target to minimize or eliminate the display of two symbols for the same intruder/target on the CDTI of an aircraft. The method comprises the steps of receiving ADS-B data at a processing unit and calculating select component deltas for the ADS-B data versus an entry in a TCAS intruder file. Progressive weights are assigned to the deltas and the progressive weights are summed, resulting in a total confidence score. Total confidence scores of ADS-B target and TCAS intruder pairs are compared to determine correlation between the ADS-B target and the TCAS intruders.

  • Patent number: 6957130
    Abstract: The present invention provides an aircraft navigational system including a graphical user interface that is capable of displaying navigational information in a split-screen format. The split-screen format includes displaying multiple graphical user panels, each depicting different traffic information. For example, one of the panels displays a plurality of air traffic symbols corresponding to airborne obstacles and another of the panels simultaneously displays ground traffic symbols representing ground obstacles. The obstacles can include other aircraft in the air and on runways as the pilot's aircraft approaches for a landing. The navigational system also is capable of switching between a single graphical user panel and multiple panels in response to a triggering event, such as a change in the course of the aircraft.
