Abstract: The portable alarm system for coffins is a system that enables a person who has been mistakenly interred to transmit a signal that indicates that he/she is alive. The system includes a signal transmitting structure removably secured in the coffin or tomb. A lamp or light source provides illumination for the tomb or coffin to allay the effect of panic for the entombed person. A receiving device is located in a prominent place, whereby the transmitted signal may be readily and quickly observed by security or other personnel. After a predetermined period, the system can be easily removed from the coffin for reuse.

Abstract: An apparatus and method for generating post-burial audio communications from surviving friends and loved ones in a casket by providing a burial casket, and providing an electronic audio communication system for placement in said casket to automatically electronically generate post-burial communications in said casket. The burial casket is thus adapted with an audio message system containing electronically stored audio and music files that are automatically played in accordance with a programmed schedule thereby allowing surviving members means for communicating to the deceased for a period of time after burial. An electronic device having a data storage system for storing recorded audio, such as messages from family and friends, music, or any other suitable audio file is provided. A timing mechanism maintains track of the date, day, and time, to allow for the selective broadcast of audio content automatically in accordance with user programmed and selected scheduling.

Abstract: A novel real time multimedia communication system links a deceased and the bereaved members of a family. The system of this invention is comprised of three elements: (1) the casket at the burial site installed with a sound and image transferring unit; (2) the family at home controlling the sound/image transfer unit in the casket; and (3) a relay station between the two transfer unit. The sound and image transfer unit, including but not limited to, videophone, computer and video camera combined with audio speakers. The sound and image transfer unit installed in the casket operated by the electric power generated by solar cell plates located on the tomb stone and/or surface ground above the buried casket. Sound messages such as music and voice, and graphic messages such as a letter, picture and moving images are transferred to each other by a wireless and wire relay station such as a website of internet, radio/television station.

Abstract: A WDM optical communication system is provided that includes a transmitter and a receiver. An optical fiber transmission path couples the transmitter to the receiver. The transmission path includes at least one repeater having an optical amplifier located therein. A dispersion compensator is disposed at an intermediate point along the transmission path. The intermediate point is located outside of the repeater. The compensator includes a wavelength routing device for dividing a signal having a prescribed bandwidth into a plurality of distinct sub-bands. A plurality of output paths is provided for respectively receiving the plurality of distinct sub-bands. The dispersion compensator also includes a dispersion compensating optical element coupled to each of the output paths. Each dispersion compensating optical element substantially compensates for dispersion at a prescribed wavelength within the bandpass of its respective sub-band.
