    摘要： An ultrasonic-based person detection method. The method comprising the steps of: (a) emitting, from an emitter, an ultrasonic signal, the ultrasonic signal including a component at a first frequency; (b) receiving reflections of the ultrasonic signal, the received signal including components at frequencies greater than and less than the first frequency; (c) determining a difference between an upper portion of the received signal containing a frequency higher than the first frequency, and a lower portion of the received signal containing a frequency lower than the first frequency; and (d) determining, based on the difference between the upper portion and the lower portion, whether a person is present.

    摘要： A method for detecting a vehicle intrusion includes a first signal transmission process for alternately transmitting a first signal of a waveform through a first transmission module and a second transmission module at a predetermined period, a first intrusion determination process for analyzing a reflected wave received in response to the transmitted first signal to determine whether the intrusion occurred, a second signal transmission process for transmitting a second signal of a pulse waveform, upon detecting the intrusion as a result of the first intrusion determination process, a second intrusion determination process for analyzing a waveform of a reflected wave received in response to the transmitted second signal to determine whether the intrusion occurred, and transmitting a predetermined alarm message indicating that the intrusion occurred upon detecting the intrusion as a result of the second intrusion determination process.

    摘要： Awareness of a device, such as a robot, to proximate humans (or other moving object) is manifested by a visual signal aligned with—i.e., aimed at—the human. For example, an illumination system may take the form of a closed or partial ring around which lighting elements may be selectively activated.

    摘要： An object detection device comprises an active sensor, an amplifying circuit configured to divide and amplify a sensor signal outputted from said active sensor with respect to each a plurality of frequency bands through each amplifier, and a determining unit determining the presence or absence of a detection target object by comparing an output of said amplifying circuit with a predetermined threshold value. A noise determining unit controls a switching circuit so as to turn off a switch inserted between said determining unit and an amplifier having a band pass including a noise of a particular frequency, when determining that the noise of the particular frequency is produced constantly by using an analysis result outputted from a frequency analyzer detecting intensity of each frequency of the sensor signal.

    摘要： A system and method are presented for determining the detection and location of persons and objects using ultrasonic acoustic sensors. The system allows detection of stationary and moving persons and other objects, through atmospheric conditions, to a distance of at least 300 feet. The invention further provides for enhanced signal processing through the use of arrays of transmitters and receivers, where one or more transmitter arrays may be oriented substantially perpendicularly to one or more receiver arrays, allowing high directionality and good rejection of reverberations, background noise, clutter and objects not of interest.
