Apparatus and methods for enhanced wireless determination of a position and direction of a smart device. Wireless transceivers controlled by the smart device communicate with reference point transceivers to generate data sufficient to determine relative positions of the wireless transceivers and a direction of interest. Operation of one or both of a magnetic force sensor and LIDAR may be operative to verify the position and direction of the Smart Device.

Introduced here are recording devices optimized for recording speech between multiple parties (e.g., a speaker and a counterparty, or a first speaker and a second speaker). These recording devices can facilitate the discovery of personalized characteristics of an interaction by detecting location. For example, these recording devices can discover the intent behind certain terms and phrases in the context of a conversation. A recording device can include a communication module configured to stream recorded media content to another electronic device, as well as a marker identification module configured to identify nearby beacons. For example, a recording device may include a Bluetooth Low Energy chipset configured to identify nearby Bluetooth beacons and a Wi-Fi chipset configured to stream recorded media content to another electronic device.

There may be provided a method for proximity sensing by a computerized device, the method may include transmitting, by at least one transmitter of a computerized device and during at least one transmission window, one or more transmitted signals, the one or more transmitted signals comprise a transmitted ultrasonic signal; operating at least one receiver of the computerized device to receive, during at least one reception window, one or more received signals that were reflected or scattered due to the transmitting; processing the received signals to provide a processing result, when receiving the received signals by the receiver during the at least one reception window; and determining a proximity of one or more objects to the computerized device based on at least one out of (a) an absence of received signals during the at least one receive window, and (b) the processing results

The disclosed threat response system(s) and method(s) provide a mean to secure an area efficiently, safely, effectively and around the clock. The system includes a plurality of microphones strategically located at various locations of the protected area, a plurality of acoustic beacons to provide navigational support one or more autonomous non-flying (ANF) drones, and a central controller. Each of the one or more ANF drones can be equipped with an acoustic positioning system that uses beacon signals (e.g., mechanical waves) transmitted by the plurality of acoustic beacons to determine its position relative to the plurality of acoustic beacons. Once an acoustic event is detected, it can be analyzed to determine whether there is a threat. If the threat is confirmed, the central controller can dispatch one or more of the ANF drones to investigate and/or to engage the target.

A laser marking method for an electronic device with a projector and a projection screen includes first and second microwaves being received by microwave receivers on corners or elsewhere of the projection screen. First and second microwave transmitters in a laser pen transmit the microwaves. Time intervals between transmissions and receptions of the microwaves are acquired. Distances between each of the microwave receivers and each of first and second microwave transmitters are calculated, to establish a three-dimensional rectangular coordinate system. Coordinate value of a point on the screen struck by laser beam (drop point) from the pen is calculated. The method allows for marking the drop point on the screen and also for marking a series of drop points with a line when the laser beam moves across the screen.

The disclosure relates to a method for requesting and granting priority between a host vehicle and other vehicles, and to a system which implements the method. The host vehicle, through the use of on-board vehicle sensors, detects and identifies an impeding vehicle which interferes with the host vehicle's path. The host vehicle transmits a priority request to the impeding vehicle. The priority request includes a remuneration offer. The impeding vehicle evaluates the priority request, including the sufficiency of the host vehicle's remuneration offer, and grants or denies the host vehicle's priority request. If granted, the impeding vehicle modifies its path to be less impeding to the host vehicle, for example by assuming a cooperative path that lets the host vehicle pass the impeding vehicle.

A system for a vehicle includes a trio of ultrasonic sensors, and a controller configured to, responsive to a location of an object identified from a distance between the ultrasonic sensors, a receive time at each of the ultrasonic sensors associated with a same ultrasonic pulse from a transmitter of the object, and an absence of data regarding a send time of the ultrasonic pulse, steer the vehicle to the object.
