Abstract: A spectrometry method and apparatus for filtering step-like pulses output by a preamplifier to measure the energy or other desired characteristics of events occurring in a detector attached to the preamplifier. The spectrometer provides a set of filters that are capable of measuring the desired characteristic with different accuracy or resolution, detects the pulses in the preamplifier signal, and measures the time between consecutive pairs of detected pulses. For each detected pulse, the spectrometer selects a filter from the set of available filters, based on the measured time intervals between the pulse and its immediately preceding and succeeding detected pulses, applies it to the pulse, and indexes the output of the filtering operation with one or more indices identifying the selected filter.

Abstract: Described is a technique to produce a user interactive movie having the capability of switching perspectives at the option of the user. The movie is in the form of a computer memory means having certain information recorded thereon. The information includes a digital database and preferably sets of computer instructions. The digital database is divided into a first portion and a second portion. The first portion of the digital database contains a chain of events as perceived from a first viewpoint and the second portion of the digital database contains the chain of events as perceived from a second viewpoint. The memory means preferably includes instructions for causing a computer to retrieve and output to a user through user interfaces the chain of events from either the first portion of the digital database or the second portion of the digital database, one at a time.

Abstract: Interactive movie techniques disclosed include dialogue lines for computer users, gateways for entering alternate storylines, techniques for conveying information relating to a character's thoughts and memories, techniques for conveying character information to the user by selection of character backgrounds, the use of icons to signal the presence of additional storyline information or user activities as an interactive movie character, and techniques to draw the user into the flow of the storyline to impart the experience of "having been there".

Abstract: A user/PC interface is described that enables the user to interact with, and control, in part, the display and sequence of multimedia information. Techniques provided include presenting dialog lines for computer users and gateways for entering alternate storylines. Additional techniques are presented for conveying information related to a character's thoughts, memories and background. Icons are presented to signal the presence of additional storyline information. Other icons allow the user to become an interactive movie character in order to draw the user into the flow of the storyline and impart the experience of "having been there.
