Abstract: Hardfacing is applied on gage surfaces of bit blades, the leading and trailing edges of bit blades, and on carbide inserts. The gage surfaces contains natural diamonds, synthetic diamonds, thermally stable polycrystalline (TSP) diamonds and carbide inserts, and the hardfacing is applied over at least a portion of them. As primary cutters on the bit blades are worn down during drilling, the gage surfaces of the bit blades are also worn down. A hardfacing is applied to the worn gage surfaces of the bit blades, thereby allowing the drill bit to drill deeper and longer without requiring replacement.

Abstract: An integrated position and direction system is disclosed that includes a digital compass and a satellite positioning system (SATPOS) having a receiver adapted to receive satellite position determining signals. Direction is determined using the digital compass and heading is determined using the SATPOS. The integrated position and direction system is operable to display, on a display device, map information that is oriented according to a current orientation regardless of whether the system is stationary or moving. The map display is oriented according to either heading determined using the satellite positioning system or direction determined using the digital compass. The integrated position and direction system updates the map display to orient the map display with a current position. Moreover, the integrated position and direction system updates the map display to orient the map display with a current orientation (e.g., heading or direction).

Abstract: An integrated position and direction system and method thereof for determining drift. The integrated position and direction system comprises a satellite positioning system and a digital compass. The satellite positioning system is used for determining position and heading, and the digital compass is used for determining direction. An amount of drift can be determined using the heading and the direction. Knowing the amount of drift, a course compensating for the drift can be determined. Thus, a craft that has drifted from its planned course can be directed to a course that will allow it to reach its intended destination.

Abstract: A method and system for generating and maintaining a database comprising a location-sensitive timetable. At multiple locations, a device (e.g., an integrated position and direction system) listens for broadcast signals from broadcasting devices (e.g., Global Positioning System satellites). For each location, the device records the time and date and the number of satellites from which a signal is received. The device can also record the identities of satellites that can and cannot be picked up. The information recorded by the device can be used to automatically generate a timetable showing the dates and times of day for each location that are and are not satisfactory for doing data maintenance, based on the number of satellites available for viewing. The recorded information can also be used to automatically predict future dates and times for each location that will or will not be satisfactory for data maintenance.

At a first location, the integrated position and direction system is oriented to the offset feature and is operated to determine a first set of measurements relative to the offset feature using the digital compass and the satellite positioning system. At a second location, the integrated position and direction system is oriented to the offset feature and is operated to determine a second set of measurements relative to the offset feature using the digital compass and the satellite positioning system. The integrated position and direction system calculates the position of the offset feature using the first and second sets of measurements.

Abstract: A signal conversion device that provides RTCM correction data to a position determination device. The signal conversion device receives RTCM signals that are converted into a frequency adapted to be received by a position determination device so as to produce a converted correction signal. In one embodiment, the signal conversion device also converts the received RTCM correction data into a format that is adapted to be received by the position determination device. In one embodiment, the received RTCM signal is converted into is the Wide Area Augmentation System (WAAS) format. Alternatively, the signal is converted into a different format such as a particular manufacturer's own format. The converted correction signal is coupled to a position determination device via a wireless link. The position determination device uses the RTCM correction data contained in the converted correction signal for accurately determining position.

Abstract: A method and apparatus for coupling data from an external data device to a position determination device. An Auxiliary Data Transmission Unit (ADTU) that includes a radio transmitter couples to the external data device. The ADTU receives serial data from the external data device and encodes the received serial data into a format suitable for receipt by the position determination device. The encoded data is then modulated to produce a radio signal that is transmitted to the position determination device in a scheme that permits multiple devices to communicate with the position determination device without interference.

Abstract: An integrated circuit substrate is made by exposing a mask to a composite representation of the pattern of integration of several different dice. The mask is exposed several times to produce several composite representations on the mask. Several different composite representations may be formed on the same mask. Identical aligned composite representations are checked by optically comparing corresponding dice in different composite representations via respective optical systems. The several composite representations on the mask are transferred simultaneously to the substrate to reproduce the pattern of integration of the dice at a plurality of locations in the substrate.
