  • Patent number: 6038777
    Abstract: A sight reduction apparatus includes a sextant, a processor, and a nautical almanac, preferably all provided in an unitary housing. The sextant includes a fixed telescope which is pointed at a known celestial body, and a radial arm is moved against an arc graduated in degrees until a mirror mounted on the sextant reflects an image of the horizon down the telescope to coincide with the known celestial body. The angular elevation of the celestial body, corrected for the exact time and date, gives the position of the user on an imaginary circle. The nautical almanac provides essential data for determining the location of a predetermined list of celestial bodies relative to a fixed location. The processor is programmed to determine the position of a user based upon measurements made with respect to two celestial bodies using the sextant and information provided in the nautical almanac and to further provide the position of a user in terms of latitude and longitude.

  • Patent number: 5554031
    Abstract: In a preferred embodiment, a method of training a child for reporting an emergency on a telephone system of the type having an emergency access code, the method including: providing controllable memory apparatus in which at least one training scenario is recorded; providing a first telephone coupled to the controllable memory apparatus; providing a controller coupled to the controllable memory apparatus to cue selected portions of the recorded training scenario to transmit the same to the earpiece of the first telephone; having a child dial the emergency access code on the first telephone; and cuing successive selected portions of the recorded training scenario to elicit answers from the child, over the first telephone, to questions asked in the selected portions, such answers being of the type required by an emergency dispatcher to at least ascertain the location of the emergency.

  • Patent number: 5456605
    Abstract: A telephone training device to be operated by children or someone without a working knowledge of telephones, uses at least one working telephone, and a memory to store a first set of numbers, a receiver to accept a second set of numbers, a comparator to compare the second set of numbers to the first set of numbers, and a tone generator. The tone generator generates one tone when the handset is removed from the telephone, a second tone when the second set of numbers is different from the first set of numbers, and a third tone when the second set of numbers is the same as the first set of numbers.

  • Patent number: 5188533
    Abstract: A three-dimensional indicia bearing unit, including a voice synthesis chip, battery and amplifier/speaker (8) for synthesizing an audible sound for educational purposes such as an interactive method for learning to read. The audible sound produced is the name and/or associated sound of the indicia bearing unit. The indicia bearing unit may be a letter, number, or alternatively, short vowel, long vowel form of a letter to produce the audible sound of the phonetic pronunciation of the letter. A plurality of unique indicia bearing units organized in a selected sequence form a set retained in a book like holder. The chip, battery and amplifier/speaker may be self-contained within each indicia bearing unit.

  • Patent number: 4672438
    Abstract: A simulator is used with an optical locking device such as a cinetheodolite to provide inexpensive, convenient operator training. The simulator has a video monitor mounted on the viewer of the theodolite to display simulation images to an operator. A television camera mounted on the main telescope of the theodolite feeds a background image to the monitor. A graphics generator superimposes a target image on the background image. The movement of the telescope is coordinated with the movement of the target image on the monitor to provide a realistic simulation.

  • Patent number: 4310884
    Abstract: In accordance with the invention, satellite navigation, receiver system of an exploration system for exploring for hydrocarbons in earth formations can be tested for fieldworthiness using a portable microcomputer-controlled satellite navigation simulator. From encoded inputs of local latitude, longitude, Greenwich mean time and antenna height, both array data parameters and real-time control signals are generated for simulating signals of an orbiting TRANSIT navigation satellite vis-a-vis the satellite navigation receiver system. To such system the received signals are indistinguishable from conventional TRANSIT satellite navigation signals. Result: by merely cross-checking simulator "turn-key" encoded data with the final computed fix, a technologist (who need not be a programming expert) can determine the fieldworthiness of the satellite navigation receiver system.

  • Patent number: 4267646
    Abstract: A device for training individuals, particularly children and the handicapped, in the use of a telephone. The training device may be employed in either a single telephone mode or a dual telephone mode. In the single telephone mode a primary telephone is initially programmed with a known telephone number by switching to a program mode and dialing the number with a conventional telephone dial. The telephone is then switched to a use mode and the student is asked to dial the programmed number. As each of the digits is correctly dialed a light corresponding to each digit is sequentially illuminated and an audible signal is heard. When all of the digits have been correctly dialed, an audible ring is sounded. If any of the digits is incorrectly dialed, power is removed from all of the previously illuminated lamps, and the student must once again start dialing the telephone number at the first digit. The number of digits in the telephone number can be selected to be either three or seven digits.
