Abstract: An audience measurement system generates signatures of unknown pieces of content viewed by panel members, and generates multiplexed reference signatures of known pieces of content. The signatures of the unknown pieces of content are stored and transmitted to a central processing site, where they are compared with the reference signatures for their identification. A signature comparator finds matches between the signatures of the unknown and the known contents.

Abstract: Example methods disclosed herein to identify media sources comprise obtaining monitored signatures generated from monitored media, comparing the monitored signatures with reference signatures generated from reference media provided by a plurality of reference sources, determining tracking segments associated with respective ones of the reference sources, each tracking segment representing sequences of matches between the monitored signatures and respective reference signatures for a respective one of the reference sources, and evaluating time lengths of the tracking segments to identify which reference source in the plurality of reference sources provided the monitored media.

Abstract: An audience measurement system generates signatures of unknown pieces of content viewed by panel members, and generates reference signatures of known pieces of content. The signatures of the unknown pieces of content are stored and transmitted to a central processing site, where they are compared with the reference signatures for their identification. A scanning engine finds matches between the signatures of the unknown and the known contents, and stores matches so as to build “tracking segments”, i.e., strings of matches that indicate a coincidence between the unknown content and one or more known pieces of content for a certain period of time, and associates the unknown content to the known piece of content with the longest tracking segment.

Abstract: A method for expanding the command capabilities of pointing devices based on periodically sampling a cursor's position on a display device and analyzing the time-variation of a cursor-heading signal obtained from said samples. Upon detecting characteristic cursor-heading time-variation profiles in the cursor trajectory, commands signals are generated so that moving the cursor along particular trajectories is equivalent to activating virtual-buttons of said pointing device. A plurality of applications of the invention and a variety of embodiments are discussed.

Abstract: A mouse driver arrangement combining a first functional block, comprising a scrolling-rate function generator for generating a time-dependent scrolling-rate control signal of pre-defined shape, whose output cycle is a function of the activation status of one or more mouse push-buttons, plus a second functional block, comprising a cursor trail analyzer for detecting a dominant direction in a cursor trail and setting a scrolling direction option accordingly. The scrolling-rate function generator includes an integrator for producing ramp-like scrolling-rate control signal segments of adjustable slopes under control of the mouse push-buttons. The output of both first and second functional blocks are combined in a scrolling-vector status variable, whose magnitude is controlled by the scrolling-rate function generator and represents the scrolling rate, and whose direction is set by the cursor trail analyzer and represents the scrolling heading.

Abstract: An improved mouse for concurrent cursor position and scrolling control is disclosed, in which a supplementary scrolling control device with a double reluctance characteristic is included for achieving a double operational mode using a single finger of the hand that holds and operates the mouse. The double mode operation is combined with an improved method for performing scrolling axis settings and scrolling scale settings through a number of combined mouse movements or gestures for dynamically controlling scrolling at the same time the mouse is operated.

Abstract: In a manual input device for controlling a cursor on a computer display (e.g., a mouse), a supplementary proportional control device including a spring-loaded lever displaceable from an equilibrium position in either of two directions and protruding out of the mouse housing is provided for concurrently controlling the scrolling operation. The supplementary control signal is generated in response to operation of a lever designed to be driven by the thumb of the same hand which holds the mouse. The control signal varies according to the discplacement amount of the lever from its equilibrium position and the displacement direction and thus is used as a scrolling rate and direction control. An associated method is provided for setting the scrolling direction in correspondence to the dominant axis of the cursor's trail. Detecting an approximately circular movement of the cursor sets the scrolling axis perpendicular to the screen plane (i.e., in a third dimension).
