Publication number: 20050265264Abstract: A meeting effectiveness indicator provides information to participants of a meeting. The information includes messages that the meeting has gone off topic, and resources are being wasted. Participants within a room or local vicinity of the indicator used wired or wireless transmitters to send indications that the meeting is going off topic. Remote participants linked to a network also send indications via a network interface. Once a total number of indications reaches a warning threshold, the indicator warns the participants that the meeting is going off topic with a warning message. If additional indications are received, then the total number of indications will reach a tangent threshold, and the participants are alerted using a tangent message that the meeting is off topic.Type: ApplicationFiled: May 27, 2005Publication date: December 1, 2005Inventors: Dean Hering, John Dixon, Robert Dougherty

Publication number: 20050206874Abstract: Ranges and transverse coordinates of point light sources are estimated by forming an out-of-focus image of the point light sources using a camera. The out-of-focus image is formed such that it is imaged as a disk or ring having a bright periphery. This is conveniently achieved by taking advantage of under- or overcorrected spherical aberration in the lens, or of diffraction effects caused by the interaction of light with the aperture of the lens. Range estimates can be calculated from a size metric of the disk or ring, which in turn can be accurately determined due to its bright periphery. Range estimates can also be obtained using certain pattern matching methods.Type: ApplicationFiled: March 19, 2004Publication date: September 22, 2005Inventor: Robert Dougherty

Publication number: 20040125228Abstract: Range estimates are made using a passive technique. Light is focussed and then split into multiple beams. These beams are projected onto multiple image sensors, each of which is located at a different optical path length from the focussing system. By measuring the degree to which point objects are blurred on at least two of the image sensors, information is obtained that permits the calculation of the ranges of objects within the field of view of the camera. A unique beamsplitting system permits multiple, substantially identical images to be projected onto multiple image sensors using minimal overall physical distances, thus minimizing the size and weight of the camera. This invention permits ranges to be calculated continuously and in real time, and is suitable for measuring the ranges of objects in both static and nonstatic situations.Type: ApplicationFiled: January 17, 2003Publication date: July 1, 2004Inventor: Robert Dougherty

Patent number: 6616347Abstract: Ranges of objects are determined using a camera equipped with a rotating optical axis displacement unit (ODU). The ODU receives light about an offset line of sight, and displaces it to a substantially parallel camera line of sight. The displaced light is focussed onto an image sensor. Images of a scene are captures as the ODU rotates. Range information is calculated from the apparent motion of objects in the captured images.Type: GrantFiled: September 29, 2000Date of Patent: September 9, 2003Inventor: Robert Dougherty

Patent number: 5737025Abstract: In the present invention, an ancillary code is added to a composite video signal in its active video portion. The ancillary code may be spread over several frequencies and summed at the output of a decoder to enhance the legibility of the ancillary code at the output of the decoder. Frequency-stepping may be used to add the ancillary code at ones of a plurality of selected frequencies within the bandwidth of the composite video signal. The ancillary code may be hierarchically apportioned between respective uniquely specified sequential segments corresponding to many distribution points of the composite television signal. This hierarchical ancillary code may be frequency-interleaved between harmonics of the horizontal sync frequency of the composite video signal. The ancillary code may be redundantly added above and below the roll-off frequency of a VCR.Type: GrantFiled: February 28, 1995Date of Patent: April 7, 1998Assignee: Nielsen Media Research, Inc.Inventors: Robert A. Dougherty, David A. Kiewit, Daozheng Lu, Henry B. Wheeler

Patent number: 5737026Abstract: In the present invention, ancillary data is modulated onto a carrier frequency which is within a low energy density portion of a frequency band of a video signal, and the modulated carrier data is combined with the video signal so that the modulated carrier is in an overscan region of the video signal. The ancillary data may be spread over several frequencies and summed at the output of a decoder to enhance the legibility of the ancillary data at the output of the decoder. Frequency-stepping may be used to add the ancillary data at ones of a plurality of selected frequencies within the frequency band of the video signal. The ancillary data may be hierarchically apportioned between respective uniquely specified sequential segments corresponding to many distribution points of the video signal. This hierarchical ancillary data may be frequency-interleaved between harmonics of the horizontal sync frequency of the video signal.Type: GrantFiled: June 7, 1995Date of Patent: April 7, 1998Assignee: Nielsen Media Research, Inc.Inventors: Daozheng Lu, Henry B.

Patent number: 5629739Abstract: An ancillary signal is injected into a program signal within the frequency band normally occupied by the program signal alone. The program signal includes a modulated carrier having a carrier frequency and a low energy density portion of the frequency band. The ancillary signal is selectively added at an injection frequency within the lower energy density portion of the frequency band so that the injection frequency is locked to the carrier frequency and to the frequency of a local oscillator.Type: GrantFiled: March 6, 1995Date of Patent: May 13, 1997Assignee: A.C.
