Patent number: 7715789Abstract: Method affecting the interior of human flesh, providing modulated power signal to at least one solenoid to create a modulated solenoid action delivered through a mechanical interface to the human flesh to create a modulated audio effect into the interior. Providing the modulated power signal may include receiving an audio signal to create the modulated power signal, which may include fetching a down-converted audio signal and the audio signal from a memory device and/or frequency-down-converting the audio signal to create the down-converted audio signal. Receiving the audio signal may further include solenoid amplifying the down-converted signal to create the modulated power signal. The modulated audio effect into the interior of the human flesh, the modulated power signal and the down-converted audio signal are products of this method. Apparatus implementing the solenoid amplifying, receiving the audio signal, frequency-down-converting the audio signal in a variety of configurations.Type: GrantFiled: January 20, 2006Date of Patent: May 11, 2010Assignee: Song ParkInventors: Song Park, Earle Jennings, Robert Spence, John Larsen

Publication number: 20100085188Abstract: A method and system for detecting and classifying intruders is provided. A noise threshold can be determined and set based on background noise. A seismic sensor can be configured to receive a plurality of seismic data signals. A microcontroller can be configured to count the number of times the noise threshold is exceeded over a defined time interval by the plurality of seismic data signals, and then detect and classify the presence of an intruder based on the count. Additionally, an amplitude evaluation module can be configured to determine a signal amplitude for the seismic data signals associated with the detected intruder and compare the detected intruder signal amplitude to known signal amplitudes in order to determine a sub-type of the intruder. Finally, a transmission source can be configured to transmit intruder detection and classification information to a remote location.Type: ApplicationFiled: September 9, 2009Publication date: April 8, 2010Inventors: Peter C. Herdic, Robert M. Baden, Brian H. Houston, Phillip A. Frank, Alain R. Berdoz, Jeff M. Byers

Patent number: 7680283Abstract: A method and system for detecting a predetermined sound event, such as the sound of breaking glass. Data representing monitored sounds is stored, such as in a circular buffer, while a preliminary assessment is made in real time as to whether the monitored sounds potentially include the predetermined sound event. If there is a potential correspondence, the already stored, pre-event data is frozen, and additional data including, and following, the event is stored. Next, the stored pre-event and additional data is retrieved from storage and provided to a processor that applies one or more algorithms to determine, with finality, if the event corresponds to the predetermined sound event.Type: GrantFiled: February 7, 2005Date of Patent: March 16, 2010Assignee: Honeywell International Inc.Inventor: Kenneth G. Eskildsen

Publication number: 20090303042Abstract: This invention is an intruder detection system which integrates wireless sensor network and security robots. Multiple ZigBee wireless sensor modules installed in the environment can detect intruders and abnormal conditions with various sensors, and transmit alert to the monitoring center and security robot via the wireless mesh network. The robot can navigate in the environment autonomously and approach to a target place using its localization system. If any possible intruder is detected, the robot can approach to that location, and transmit images to the mobile devices of the securities and users, in order to determine the exact situation in real time.Type: ApplicationFiled: October 30, 2008Publication date: December 10, 2009Applicant: National Chiao Tung UniversityInventors: Kai-Tai Song, Chia-Hao Lin, Chih-Sheng Lin, Su-Hen Yang
