摘要： An electronic mail system and method enables the originator of a message sent by electronic mail to select a date, time, or event at which the message and all incarnations of the message to self-destruct, regardless of the number and types of computers or software systems that may have interacted with the message. The system and message also permits the originator to include processing and handling limitations. The necessary control over the message is achieved by encrypting the message and enabling viewing only through a viewer applet arranged to facilitate destruction of the message upon the occurrence of the selected expiration time, date, or event, and to implemented the handling and processing limitations. A central server can be used to exercise additional control over the message by serving as a proxy destination, and by streaming the encrypted message to the viewer applet. The viewer applet can be transmitted to new recipients with the message so that the system and method can direct mail to any electronic mail user.

摘要： A particle mass spectrometer includes a supersonic flow expansion nozzle, and a source of a gas having particles entrained therein. The source is in gas-flow communication with an inlet of the expansion nozzle. The particle mass spectrometer further includes a vacuum chamber in gas-flow communication with an outlet of the expansion nozzle, wherein the vacuum chamber has a sufficient vacuum that a gas flow through the expansion nozzle is supersonic, and a microphone having an active element and an output signal responsive to a movement of the active element. The active element is disposed within the vacuum chamber and is positioned so that particles that flow from the outlet of the expansion nozzle impact upon the active element. The output signal of the active element of the microphone is a measure of the masses of the entrained particles.
