A digital signal processor (DSP) is utilized to detect the progress tone and to convert audio messages to text using speech to text techniques. The operations of the DSP are controlled by the user performing operations on the keypad of the wireless telephone.

Abstract: Finishing an end of a plastic optical fiber by ablating the end of the plastic optical fiber by utilizing an Excimer laser so that the end of the optical fiber can be used in a optical connector. A high powered ultraviolet beam of light from the laser is absorbed by the end of the fiber and ablates the first few microns of the end face of the fiber. This process removes residual cracks and fissures to flatten the end of the fiber for use in the optical connector. The optical fiber is then ready to make a low loss interface with a source, a detector, or another optical fiber.

Abstract: Fabricating graded index plastic optical fiber by diffusing a high molecular weight dopant within a step index plastic optical fiber after the step index plastic optical fiber has been drawn from a preform using a conventional draw tower in a first embodiment. Also, the step index plastic optical fiber may be fabricated by extruding one material circumferentially around another material, e.g., by use of a concentric nozzle. The dopant is diffused after the drawing or extruding of the step index plastic optical fiber by heating the plastic optical fiber to a temperature that causes a high rate of diffusion state while measuring the transmission bandwidth of the plastic optical fiber. When the predetermined specified transmission bandwidth is measured, the plastic optical fiber is immediately returned to an ambient temperature. In addition, the plastic optical fiber may be gradually heated to an equilibrium temperature that is just below the temperature required to produce the high rate of diffusion state.

Abstract: The present noninvasive load and pressure sensing system makes use of a transparent pressure vessel that is filled with a compressible fluid, whose refractive index changes as a function of the pressure applied to the compressible fluid to redirect the path of a light beam that is transmitted through the transparent pressure vessel. An incident beam of coherent monochromatic light is applied to a transparent segment of a wall of the transparent pressure vessel, where this incident light beam is refracted by the compressible fluid contained in the transparent pressure vessel. The refracted light beam traverses the transparent pressure vessel and exits the transparent pressure vessel at a point along the opposite wall of the transparent pressure vessel as determined by the refractive index of the compressible fluid, which is determined by the pressure of the compressible fluid.

Abstract: A telephone terminal that allows simple word commands to produce different results depending on the identity of the caller. The use of a limited set of word commands allows the utilization of an inexpensive voice recognition subsystem. A first single word command results in a caller from a first group of people being immediately placed on a speakerphone; whereas, a caller from a second group of people receives the audio message "Please stay on the line a few seconds, and I will personally answer your call". Further, for the same audio command, the called party can pre-record an audio message for the first group; whereas the second group always receives a voice synthesized message. A second single word command results in a caller from the first group of people receiving an audio message that states "The name of the caller, I will call you in five minutes". Whereas, a caller from the second group of people receives the audio message "Please call back in five minutes".

Abstract: A telephone set and method for controlling what calls are forwarded to the telephone set. The telephone set has a terminal processor having an internal memory in which are stored a control program and data. The terminal processor under control of the program controls operation with respect to forwarded calls using the data. In response to the data, the terminal processor can block all forwarded calls from all other telephone sets, from a predetermined list of telephone sets, or from all telephone sets except for a predetermined list of telephone sets. Call forwarding can be blocked from a single forwarding telephone set not known to the user of a telephone set by the user actuating a button during a forwarded call being processed from the forwarding telephone set. In addition, the terminal processor can block all forwarded calls except those from other designated telephone sets.

Abstract: Allowing the ability to specify a general frame format and to automatically recognize similar frames at later points in time. A user initially selects the type of frame by watching a particular program such as the weather portion of a newscast and selects the desired frame using a hand-held control unit similar to the present hand-held control units for VCRs or television sets. When the frame appears on the television set, the user presses a button on the hand-held control unit, and the apparatus stores the frame that is presently being displayed. The apparatus then analyzes the stored frame to determine a set of recognition parameters. Those parameters are used to recognize similar frames in subsequent broadcast segments and to store one of those recognized frames for each broadcast segment. The user also specifies a time period during which the system will search for the specified frame. Further, the audio portion of a program segment is stored as long as frames are being recognized in that segment.

Abstract: An apparatus that allows a pager to select a telecommunication terminal to which a telecommunications switching system terminates all incoming calls destined for the user of the pager. The selection is made under control of the user. The pager request that communication terminals transmit their identities to the pager. The pager then displays the identities of communication terminals to the user who selects one of the communication terminals to be the selected communication terminal. In response to the selection by the user, the pager signals the selected communication terminal. In turn, the selected communication terminal signals the telecommunications switching system that all incoming calls for the user of pager are to be terminated on the selected communication terminal.

Abstract: A cellular terminal for transmitting information defining its location upon placing a 911 call. The cellular terminal includes a global satellite positioning (GPS) device; and upon the user of the cellular terminal placing an emergency telephone call, the cellular terminal interrogates the GPS device to obtain the geo-coordinates. The cellular terminal then transmits the geo-coordinates to a cellular telecommunication switching system. The cellular switching system or a public safety answering point (PSAP) system responding to the 911 call converts the geo-coordinates into location information. In addition, the cellular terminal transmits to the cellular telecommunication switching system pre-defined vehicle description information if the cellular terminal is being utilized within a vehicle. If the cellular terminal is a hand held unit, the cellular terminal can be programmed to transmit personal characteristics of the person using the cellular terminal.
