Publication number: 20030189545Abstract: An acoustic based pointing device and a system and method for using the pointing device to move a cursor on a display screen of a display device. The pointing device comprises an acoustic source that generates and propagates an acoustic signal that is detected by four microphones M1, M2, M3, and M4 and is then converted into corresponding periodic electrical signals S1, S2, S3, and S4. The position vector P0 of the acoustic source is calculated by solving triangulation equations that depend on phase-shift time delays between S1 and Sj for j=1, 2, and 3. A position vector PC is calculated from P0 using a scale vector that relates a change in position of the cursor to a change in position of the acoustic source. Then the cursor is moved to a position PC associated with the position vector PC.Type: ApplicationFiled: April 8, 2002Publication date: October 9, 2003Applicant: Koninklijke Philips Electronics N.V.Inventors: Miroslav Trajkovic, Antonio Colmenarez, Srinivas Gutta

Publication number: 20030185289Abstract: A system and method for cordless communication between a modem of a computer and a communication line includes a base station and at least a remote unit. A booster station can be optionally included to increase reception to the remote unit. The base station will be adapted for connection with the communication line, and will transmit via RF to the remote unit. The base station may test the communications over a plurality of available channels and select the channel with the strongest reception. The booster station may also communicate via RF with the remote unit, and may optionally plug into an electrical outlet, and communicate with the base station over common wiring when the base station is similarly attached to another outlet of the common wiring. The system may compare reception between the base station and the remote unit with the booster station and the remote unit, and may communicate with the booster station only over the electrical wires to reduce RF transmissions.Type: ApplicationFiled: December 7, 2001Publication date: October 2, 2003Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Antonio Colmenarez, Srinivas Gutta, Miroslav Trajkovic

Publication number: 20030043990Abstract: When a call is placed to an organization seeking information from a representative of that organization, the call is frequently placed on hold for an extended period of time. After the call is made and the called party's telephone is placed on hold, the caller enters a code signal to place the call on hold. At this instant, both telephones are on hold. At some time after this “Hold On Hold” connection is established when a representative of the organization called answers the telephone and speaks to identify himself, the network identifies the signals as being generated by a live person, and a ring signal is sent to the caller's telephone to alert the caller that the call is no longer on hold.Type: ApplicationFiled: September 5, 2001Publication date: March 6, 2003Applicant: Koninklijke Philips Electronics N.V.Inventors: Srinivas Gutta, Antonio Colmenarez, Miroslav Trajkovic

Publication number: 20030040925Abstract: A method and apparatus are disclosed for monitoring a retail location using vision-based technologies to recognize predefined fraudulent events. Captured images are processed to identify one or more predefined fraudulent events and to initiate an appropriate response, such as sending notice to an employee for further investigation or recording the event for evidentiary purposes. A number of rules define various fraudulent events. For example, rules can be devised to detect when a patron is wearing stolen clothing out of the changing room, or when a patron is fraudulently attempting to return merchandise without a receipt. Each rule contains one or more conditions that must be satisfied and a corresponding action-item that should be performed when the rule is satisfied. At least one of the conditions for each rule identifies a feature that must be detected in an image using vision-based techniques.Type: ApplicationFiled: August 22, 2001Publication date: February 27, 2003Applicant: Koninklijke Philips Electronics N.V.Inventors: Srinivas Gutta, Miroslav Trajkovic, Antonio Colmenarez

Publication number: 20030030571Abstract: A collaborative speed measurement device detection system provides early warning and increased reliability by sharing the responses of multiple detectors through a broadcast radio network. A vehicle with one detector (e.g., radar, laser detector) broadcasts a detection event to any other detectors in its vicinity. The receiving detectors generate a warning signal in response to the broadcast. The receivers can combine the results of multiple detections to generate a reliability estimate. The location of the detection events may be broadcast and used in generating alarms in the receiver as well.Type: ApplicationFiled: August 13, 2001Publication date: February 13, 2003Applicant: Koninklijke Philips Electronics N.VInventors: Miroslav Trajkovic, Srinivas Gutta, Antonio Colmenarez

Patent number: 6498970Abstract: A system and method for identifying persons who are authorized to activate one or more vehicle mechanisms uses both an implicit identification of a face and an explicit identification of speech or a gesture. This system and method enables identification to be performed where a single identification is otherwise unable to perform the identification for some reason and improves the reliability and accuracy of an identification so that only authorized persons can activate the vehicle mechanisms. Vehicle mechanisms that can be activated using this multimodal identification system and method include, for example, automatic locks, automatic windows, a trunk lock, a vehicle engine, outdoor or interior lights, and a vehicle alarm.Type: GrantFiled: April 17, 2001Date of Patent: December 24, 2002Assignee: Koninklijke Phillips Electronics N.V.Inventors: Antonio Colmenarez, Srinivas Gutta, Miroslav Trajkovic
