摘要： Various techniques are described herein for using smell sensor-based Internet-of-Things (IoT) devices to detect and identify individual users based a unique scent or smell print. Interconnected networks of such devices may be used in collaboration, along with other devices such as IoT devices and home monitoring system devices, to track user movements and activities. Such smell sensor device also may be used to detect weapons, explosives, narcotics, and other prohibited items that may be concealed and/or not detectable using security cameras. The data received from the smell sensors and smell-based IoT devices may be used, alone or in combination with other security sensors and systems, to perform safety and security screening within homes, airports or other secure areas, or within any public indoor or outdoor location.

摘要： Embodiments include apparatus and method for collecting observation data for updating a geographic database. An initial observation is collected by a first mobile device, a first vehicle, or a first sensor. Along with the geographic position, data indicative of the first observation is send to a server. The central server may analyze of the initial observation data to determine if additional observations should be made and define a bounding box from the geographic position of the first mobile device and the analysis of the initial observation data. A request for additional observations is generated and sent to at least one second mobile device, second vehicle, or second sensor based on the bounding box.

摘要： A marine multibeam sonar device comprises a processing element and a transmitter. The processing element generates a plurality of transmit transducer electronic signals and inverts a polarity of a first portion of the transmit transducer electronic signals. The transmitter is in communication with the processing element and includes a plurality of transmit electronic circuits and a plurality of transmit transducers. Each transmit electronic circuit receives and processes one of the transmit transducer electronic signals, wherein a first portion of the circuits re-inverts the polarity of the first portion of the transmit transducer electronic signals. The transmit transducers receive the processed transmit transducer electronic signals from the transmit electronic circuits and generate a sonar beam.

摘要： Simultaneous 2-D room shape reconstruction and self-localization is accomplished using no pre-established infrastructure. A mobile device with co-located microphone and loudspeaker is used to collect echoes reflected by the walls. The system uniquely recovers arbitrary 2-D convex room shape as well as the position of mobile device 10 by collecting and processing distances between three consecutive measurement points as well as acoustic echoes from the device. A practical algorithm for room shape reconstruction and self-localization in the presence of noise and higher order echoes is proposed. Experimental results are provided to demonstrate the effectiveness of the approach.

摘要： The electronic equipment includes a display, an ultrasound emitter, an ultrasound receiver, and a processor. The ultrasound emitter can be adapted to emit a first ultrasound signal into at least a space the display faces. The ultrasound receiver can be adapted to receive a second ultrasound signal. The second ultrasound signal is an echo of the first ultrasound signal reflected by an object. The processor can be connected respectively to the ultrasound emitter and the ultrasound receiver. The processor can be adapted to acquire a floating touch signal by locating the object in three-dimensional space according to charactering information charactering the first ultrasound signal and the second ultrasound signal, and execute an instruction corresponding to the floating touch signal.

摘要： A system for detecting objects using ultrasonic waves and methods for making and using the same are provided. The object detection system uniquely encodes each of a plurality of ultrasonic waves and transmit each of the uniquely-encoded ultrasonic waves in a respective direction. The object detection system then receives any of the emitted uniquely-encoded ultrasonic waves that are reflected from an object. By decoding the reflected ultrasonic waves, the object detection system distinguishes among the uniquely-encoded ultrasonic waves and detect the existence and location of the object.

摘要： In an embodiment, a system and method are provided for determining position and orientation of an optical delivery unit relative to an acoustic receiving unit, in the field of opto-acoustic imaging, wherein the optical delivery unit comprises a first fiducial marker site configured to emit acoustic responses and a second fiducial marker site configured to emit acoustic responses. A plurality of acoustic signals from a volume of a subject are sampled and recorded, each of the plurality of acoustic signals being collected at a different data collection position relative to a coordinate reference frame. The system is configured to identify in each of the plurality of acoustic signals a response of a first fiducial marker and a response of a second fiducial marker. Each identified response indicates a separation between a fiducial marker site and a data collection position of an acoustic signal. The system determines the position and orientation of the optical delivery unit in the coordinate reference frame by using the identified responses of the first fiducial marker and the identified responses of the second fiducial marker.
