Inventor: SULLIVAN BRIAN T
IPC: G11B7/24
Filed: 1995-05-09
Abstract: An optical recording medium for storing data is provided having a visible logo on a read side of the medium for providing some anticounterfeiting protection. A logo coating for producing the visible logo is carried by the read-side of the substrate; the coating has a sufficiently high transmittance at a read or write wavelength such that light at the read or write wavelength passing through the logo coating toward the other side of the substrate and reflected back through the logo is substantially transmitted and \\ unchanged by the coating so that the data can be detected. As well the coating is sufficiently light absorbing in the visible spectrum such that there is a visible contrast between the recording coating and the logo coating. In another embodiment, the logo coating forms a portion of a reflective recording layer on the other non-read side of the substrate. In this case, the logo coating is visually distinguishable from the rest of the recording layer and is made of a different material. For example, the logo may be gold and the rest of the recording layer may be aluminum, or vice versa.

Abstract: A combination of frames and a ladder which comprises an outer frame which would be positioned into a wall of a basement near the ceiling and above the ground or with a excavated area adjacent to it to enable persons to escape the basement without hindrance from the ground. This outer frame houses an inner frame which could contain a window or could be a solid device however usually it would contain a window to allow light and vision of the outside where the user would escape to. This inner frame is connected to the outer frame by an assembly of sliders and spacers which allow the inner frame to move inwardly into the basement and begin sliding in a downward motion between the beams of the ladder assembly. The inner frame is supported by a solid hinged lower frame to assist in the travel of the inner frame to clear the depth of the outer frame. The lower frame hinges to a horizontal position and becomes the top step of the ladder assembly. The ladder assembly is fastened to the lower frame and with sliders to the outer frame and is unable to be removed. This basement fire escape in it's closed position would be contained within the outer frame except for the ladder assembly which would hang in a vertical position from it's connection with the lower frame and lie against the inside wall of the basement. When the ladder is pulled away from the wall it actuates a release and allows the inner and lower frame to move inward and downward through the travel of the sliders and spacers to it's open position between and below the ladder beams to rest close to the wall and out of the way of the persons climbing up the ladder to exit through the outer frame to the outside of the building. This combination of frames, ladder and sliders and spacers moves together when the ladder is moved away from the wall to a climbing angle and rests against the ground and is held in place by the lower frame to support the weight of the person using the fire escape.

Inventor: UPTON ERIC L
IPC: H04W64/00
Filed: 1997-04-16
Abstract: A method for determining the geolocation of a user terminal within  a  telecommunications  system having a  constellation of satellites  which  relay  communications  signals  between  earth stations and user terminals over preassigned channels.  The method performs synchronization upon the telecommunications signals to calculate timing and frequency update information for the user terminals.   The timing and frequency update information is also used within the earth station to calculate the geoposition of the user terminal.  To do so, the earth station calculates a distance between  the  satellite  and  a  user  terminal  based  on  the corresponding propagation time therebetween which is obtained from the timing information.   Once  the satellite to user terminal distance is obtained,  a range solution line may be calculated therefrom.  In addition, the frequency update information is used to calculate a Doppler solution line upon which the user terminal is positioned.  Thereafter, the range and Doppler solution lines are combined to obtain points of intersection therebetween.  These points of intersection represent potential geolocations of the user terminal. The  earth  station  discriminates  between  these intersection points in one of several manners, such as the coverage beam spot or geographic cell assigned to the user terminal.  Upon obtaining a single intersection point, the longitude and latitude of this point or output is the geolocation of the user terminal.
