A method of providing visualization information of a rear vehicle includes calculating a location of a sound source located behind a host vehicle, using a sound signal received by each of a plurality of microphones, matching information about the location with an object displayed on image information generated by a rear camera, and displaying a first icon indicating the object on the image information, where the first icon includes information about a probability that the object is present in an area indicated by the location information.

A technique for detecting the occurrence of an event, and for estimating other event-related information, by analyzing the barometric pressure in the vicinity of one or more wireless terminals. The disclosed detection technique is based on the recognition that the barometric sensor on various wireless terminals, such as smartphones, is capable of measuring very subtle changes in the atmospheric pressure. The disclosed detection technique is also based on the additional recognition of how some of the changes in the atmospheric pressure, as measured by a wireless terminal, correlate to various events that occur within a building or other defined area. For example, the disclosed technique can detect an entry door opening or closing by analyzing a resultant pressure wave having a particular transient that is perceptible by one or more wireless terminals in the area and analyzed by a detection engine.

A gunshot detection system utilizes an ultrasonic transducer for detecting a blast wave resulting from a gunshot. The system may be linked to alert systems configured for notifying emergency response personnel to the occurrence and location of a gunshot, thereby enabling a rapid response to an active shooter situation.

A device for preventing cables against external damage based on sound source localization comprises a power supply unit, and a sound source sensor unit, a camera unit, a signal processing unit and a wireless communication unit which are electrically connected to the power supply unit. The signal processing unit is connected to the sound source sensor unit, the camera unit and the wireless communication unit. The camera unit is associated with the sound source sensor unit. When the sound source sensor unit recognizes a target signal, the signal processing unit sends a trigger signal to the camera unit, and then the camera unit is triggered to replay a surveillance video to determine whether or not a target really exists. Compared with the prior art, the device has the advantages of being good in safety, high in reliability and the like.

Systems, apparatuses and methods are provided herein for monitoring stock information in a shopping space. A system for monitoring stock information in a shopping space comprises: a support structure configured to hold a plurality of items in the shopping space, a sound emitter device configured to produce a sound in response to a movement of at least one of the support structure and an item placed on the support structure, and a sound sensor configured to capture a sound produced by the sound emitter device and transmit the sound produced by the sound emitter device to a stock tracking system.

A method for determining the location of a first source. A first member is provided. A first tip microphone is attached to a first end of the first member. A first static microphone is provided. An initial frequency is recorded at the static microphone. The first member is rotated at an angular velocity. A tangential distance is calculated from the first tip microphone to the source. A source angle is calculated from the first member to the source. A height of the source is calculated.
