A method according to an embodiment includes receiving UWB data indicative of a distance of a mobile device relative to the access control device and a SNR of signals received by a plurality of UWB antennas, inferring a side of the passageway at which the mobile device is located based on the distance of the mobile device relative to the access control device and also based on the SNR of the signals, estimating a travel time of the mobile device to the passageway based on the UWB data if the inferred side of the passageway based on the distance of the mobile device is different from the side of the passageway inferred based on the SNR of the signals, and determining the side of the passageway at which the mobile device is located to be an unsecure side of the passageway if the travel time exceeds a predefined threshold time.

UWB-based side of door detection for intent analysis

Disclosed herein are devices, systems, and methods for accurately determining fluid level using Ultra Wideband (UWB) positioning or localization. UWB utilizes a radio-frequency (RF) technology to enable the accurate measurement of the time-of-flight of a radio signal and UWB positioning can operate in Time-Difference-of-Arrival (TDoA) mode, Two-Way-Ranging (TWR) mode, and Phase-Difference-of-Arrival (PDoA) mode. The systems disclosed herein include multiple anchor devices having a UWB antenna(s) and positioned in fixed location(s) over the fluid to be measured. The anchor devices serve as reference points for UWB communication with a remote float device, which emits RF signals and floats on the surface of the fluid to be measured. The anchor devices may include, or be in communication with, a processor which receives and/or measures RF signals, generates timestamps, calculates distance(s) between the remote float device and an anchor device, calculates fluid level, calculates an angle-of-arrival (AoA), or any combination thereof.

A method including transmitting, by a handler device associated with package handler, a message to an access control system requesting access to a secure container secured by an electronic lock mechanism; determining, by the access control system, whether the package handler is authorized to access the secure container based on the received message; transmitting, by the access control system, an unlock command to the secure container in response to a determination that the package handler is authorized to access the secure container; and unlocking the electronic lock mechanism of the secure container in response to successful authentication of the unlock command.

Wireless device power optimization utilizing artificial intelligence and/or machine learning

A system according to one embodiment includes a first computing device comprising ultra-wideband communication circuitry, and a second computing device comprising ultra-wideband communication circuitry configured to communicate with the ultra-wideband communication circuitry of the first computing device to determine the angle and distance of the first computing device relative to the second computing device.

A method for seamless access control according to one embodiment includes determining whether a user is authorized to access a passageway controlled by an access control device based on credential data received from a mobile device of the user, determining, by a RADAR system, a location of the user relative to the passageway, determining whether the user intends to access the passageway based on the determined location of the user relative to the passageway, and controlling, by the access control device, a lock mechanism to allow the user access to the passageway in response to determining that the user is authorized to access the passageway and the user intends to access the passageway.

Seamless access control

A system according to one embodiment includes an access control device comprising a lock mechanism configured to secure access to a passageway, and a UWB accessory device configured to receive a credential of the mobile device via Bluetooth communication, determine, using UWB ranging of the UWB accessory device, a location of a mobile device relative to the passageway secured by the lock mechanism of the access control device, determine whether a user of the mobile device intends to access the passageway based on the determined location of the user relative to the passageway, and communicate an indication that the user intends to access the passageway to the electronic lock via Bluetooth communication, and wherein the access control device is configured to unlock the lock mechanism in response to the indication that the user intends to access the passageway.

Ultra-wideband accessory devices for radio frequency intent detection in access control systems

A method of reducing a power consumption of wireless communication circuitry of an edge device according to one embodiment includes determining a delivery traffic indication map (DTIM) interval of a wireless access point communicatively coupled to the edge device via the wireless communication circuitry of the edge device and adjusting a wake-up interval of the wireless communication circuitry of the edge device based on the DTIM interval to reduce the power consumption of the wireless communication circuitry of the edge device.

An exemplary Internet of Things (IoT) module for a lockset includes a housing assembly configured for mounting with the lockset, a controller, a wireless transceiver, and a sensor array, and may further include an LED array. The controller is in communication with an external device via the wireless transceiver, and is configured to transmit to the external device information received from the sensor array. The controller is further configured to control operation of the LED array based on information received from at least one of the sensor array or the external device.

Internet of things lock module

A position sensing system and method for detecting the displacement of a door from a reference position, such as, for example, from a closed position. The system includes a magnetometer that may be operably connected to the door, and which measures positional location relative to a reference magnetic field, such as, for example, a magnetic field provided by a magnet of a lock device. The system may also include an accelerometer that detects acceleration of the door, and thereby provides an indication of when location is to be measured by the magnetometer. Measurement information from the magnetometer is used to derive a position indicator that is compared to a reference indicator, the reference indicator being associated with the reference position. Differences between the position and reference indicators may provide an indication that the door has been moved from the reference position.
