Abstract: ABSTRACT OF THE DISCLOSURE           Method and apparatus are disclosed for accurately determining position from GPS satellites and received on a ship using C/A code group delay observable ?, 308 fo implicit carrier phase observable ?, L1 band implicit fo carrier residual phase observable ?L1, and L2 band implicit fo carrier residual phase observable ?L2.  A precise measurement of the group-phase delay range to each satellite is made based upon the L1 center frequency carrier phase.  A correction for ionospheric effects is determined by simultaneous observation of the group delays of the wide bandwidth P code modulations in both the L1 and L2 bands.  These group delays are determined by measuring the phases of carrier waves implicit in the spread-spectrum signals received in both bands.  These carriers are reconstructed from both the L1 and L2 band signals from each satellite without using knowledge of the P code.  The unknown biases in the L1 center frequency carrier phase range measurements are determined from simultaneous, pseudorange measurements, with time averaging.  The instantaneous position of the ship may then be determined from the ranges so determined, with both the bias and the ionospheric effects having been eliminated.

Filed: 1987-12-30
Granted: 1994-05-31
Abstract: Abstract of the Disclosure A thin flexible disk of opaque material and at least one flexible disk comprised of a translucent plastic material is provided in a kit.  A shooter aims a weapon such as a rifle in the normal fashion with the optical axis of one eye aligned with the rear and front sights on the rifle.  While the rifle is being aimed, the other eye, that is, the eye which is not consciously doing any aiming, has the opaque disk applied to the lens of the shooter's glasses.  The opaque disk is then moved around until it is aligned with the pupil and on the optical axis of said other eye.  A translucent disk is then applied coincidentally with the opaque disk after which the tentatively adhered opaque disk is removed.  The shooter then proceeds to shoot with the center of vision of said other eye blanked out but with diffuse light coming through the translucent disk so the brain governs the other eye as if the eye were operating under ordinary conditions in which case depth perception, peripheral vision and binocular vision are preserved as is normally the case when an object is sighted with two unoccluded eyes.

Granted: 1991-07-23
Abstract: A METHOD AND CIRCUIT FOR SETTING DIALING DATA IN A WIRELESS TELEPHONE          ABSTRACT OF THE DISCLOSURE       An information storing apparatus is provided in a radio tele-phone apparatus having a base unit coupled to a wired telephone line and a radio telephone set. The base unit includes a memory for stor-ing telephone number information and line relay for making or breaking a speech path between the base unit and the wired tele-phone line. When a registration signal is transmitted from the radio telephone set, the base unit is disconnected from the wired tele-phone line to break the speech path. Thereafter, if a dial signal from the radio telephone set is received, the received dial signal is stored in the memory as the telephone number information used for a reduced dialog operation. If a calling signal arrives at the wired telephone line while the dial signal is being stored, the calling signal is detected by another telephone apparatus coupled to the wired telephone line. Therefore, the telephone apparatus generates a ringing signal in response to the detected signal.

Abstract: ABSTRACT OF THE DISCLOSURE       A method and apparatus for on-site remedial soil restoration activity of a work site contaminated with volatile organic compounds.  Soil is removed from the ground and hauled to an initial feed hopper whereat it is conveyed to an inlet end of a hollow rotating cylinder having plural flights therein for effecting a moving of the contaminated soil lengthwise of the rotating cylinder toward an outlet end.  The soil is heated as it tumbles about in the cylinder and the volatile organic compounds (VOCs) are volatilized inside the rotating cylinder.  The hot gases drawn from the cylinder are filtered for the purpose of removing dry soil fines.  The soil exiting the outlet end of the cylinder is thence recirculated through the rotating cylinder and thereafter fed to a conveying mechanism, whereat the cleaned soil is delivered to a selected location.  The cleaned soil is then placed into the ground.  The hot gases are scrubbed to remove therefrom any organics, acids and phosgenes.  The gases are there-after fed to a bed of activated carbon for the purpose of extracting the remaining volatile organic compounds (VOCs) therefrom and allowing the now clean air to escape into the atmosphere.

Abstract: Abstract of the Disclosure Modulating the intensity of directed energy for thermal writing of memory cells overwrites bits of either state in a storage layer of magnetic material irrespective of the preexisting condition of the cell without employing a magnetic field whose origin is external to the storage layer.  Directed energy is synchronized with the medium by superimposing, preferably nonmagnetically, self-timing information on the medium itself and synchronously recovering the self-timing information to assist in directing energy to the medium.  The medium itself has a magnetic layer plus recoverable timing information fixed in the medium along a predetermined path preferably embodied in a fixed periodic uniform variation in the nonmagnetic reflection properties along the track.
