Abstract: There is provided a system for tracking objects. The system includes a processor and a memory for storing a plurality of sensory data frames. The processor determines a first hypothesized location for each of the objects in each of the plurality of sensory data frames. For each of the plurality of sensory data frames, the processor determines probabilities that the first hypothesized location of each of the objects in a sensory data frame of the plurality of sensory data frames is the same as the first hypothesized location of another object in an adjacent sensory data frame. The processor computes a first optimal trajectory for each of the objects using an algorithm based on the probabilities, checks the first optimal trajectory for each of the objects, and accepts or rejects the first optimal trajectory for each of the objects.

Abstract: A mounting for the electronic components of computer system's functional control unit comprises a housing for supporting a display unit and for enclosing an electronics chassis comprising electronics to control access to a variety of peripheral units. The electronics chassis is removably mounted within the housing on slide rails so as to be removed, serviced or replaced without having to lift the terminal off the housing of the functional control unit. The mounting thus simplifies the installation and maintenance procedures for computer systems.

Abstract: An optically scannable answer sheet booklet is comprised of a plurality of signatures which are folded to provide the various sheets or leaves of the booklet. The opposite sides of each sheet or leaf constitutes a page of the booklet and has printed thereon certain instructions or questions as well as so-called response areas or bubbles which are to be marked by the examinee. The various signatures are each printed with a sequence bar which collectively, if the correct number of signatures are properly inserted, form a recognizable pattern. If a signature is incorrectly inserted, duplicated or omitted, the pattern will be broken or will contain an extra sequence bar which apprises the inspector of faulty booklets.
