CPC Class H04W

A conducted electrical weapon (“CEW”) launches wire-tethered electrodes from multiple cartridges to provide a current through a human or animal target to impede locomotion of the target. The CEW includes a handle and one or more deployment units. A handle and each deployment unit include a processing circuit and memory. A handle may provide operation and usage records to a deployment unit for storage. The information stored on a deployment unit may be unalterable once written. A handle may log a record of usage, deployment units, and other deployment information. The log file may be available to an electronic device through a secure wireless protocol.

A mobile-device-based system for classifying a mode of transportation during a trip includes a mobile device including a location detection system and an accelerometer. The mobile device is configured to collect location data and acceleration data during the trip. The system also includes a data processing block configured to receive the location data from the mobile device, receive contextual data related to a plurality of transportation systems, and process the location data and at least a portion of the contextual data using a first transportation mode classifier associated with a first of the plurality of transportation systems and at least a second portion of the contextual data using a second transportation mode classifier associated with a second of the plurality of transportation systems. The data processing block is also configured to classify the mode of transportation during the trip and update the classifiers based on user input.

Systems, apparatuses and methods are provided herein for tracking carts in a shopping space. A system for tracking carts in a shopping space comprises: a sound sensor array, a cart location database storing location information and sound profiles associated with a plurality of shopping cart identifiers, and a control circuit configured to: identify a cart sound made by a movement of a shopping cart traveling in the shopping space, determine a current location of the shopping cart based on the cart sound, match the shopping cart to a shopping cart identifier in the cart location database, update the location information associated the shopping cart identifier in the cart location database based on the current location of the shopping cart; and update the sound profile of the shopping cart identifier based on the cart sound captured by the sound sensor array.

A method in an electronic device includes receiving, with an audio capture device such as a microphone, a request for navigational information. One or more processors of the electronic device then identify a transit mode. The one or more processors also detect, with one or more sensors, one or more contextual cues from an environment about the electronic device. The contextual cues can include a geo-location, transit mode, bearing, or other factors. The one or more processors then provide a navigation information response that is a function of the transit mode and the one or more contextual cues to a user interface of the electronic device.

Systems and methods for environmental monitoring of high activity facilities, generally comprising low profile devices having sensing elements for various environmental uses, designed to provide the wireless communications network as a basis for performing a wide variety of tasks. The devices may be installed on an existing electrical system and may measure, among other things, electrical current on various circuits.

A system comprising synchronization circuitry, a first interrogator, and a second interrogator. The first interrogator includes a transmit antenna; a first receive antenna, and circuitry configured to generate, using radio-frequency (RF) signal synthesis information received from the synchronization circuitry, a first RF signal for transmission by the transmit antenna, and generate, using the first RF signal and a second RF signal received from a target device by the first receive antenna, a first mixed RF signal indicative of a distance between the first interrogator and the target device. The second interrogator includes a second receive antenna, and circuitry configured to generate, using the RF signal synthesis information, a third RF signal; and generate, using the third RF signal and a fourth RF signal received from the target device by the second receive antenna, a second mixed RF signal indicative of a distance between the second interrogator and the target device.
