Adaptive random-walk scheduling for ble beacon transmissions
Patent published on the 2026-05-07 in WO under Ref WO2026094013 by CARTASENSE LTD [IL] (Kaufmann Yaron [il], Berkovitch Shlomo [il], Peled Aviv [il])
Abstract: A method for Bluetooth Low Energy (BLE) advertising includes determining, by a controller of a BLE device, a next transmission time for advertising content using a bounded mean-reverting random-walk process. The determination is based on a next drift variable (Δtn+1), a base interval value (T0), and a random jitter component (J). The next drift variable is determined based on a current drift variable (Δtn), a first parameter (λ), a random variable (ξn) and a scaling factor (σ) set to determ[...]
Our summary: The method uses a bounded mean-reverting random-walk process to determine BLE advertising transmission times. It autonomously transmits content based on drift variables and a random jitter component. This approach enhances collision avoidance in dense environments by enabling desynchronization among nearby BLE devices.

System and method for deactivating the collision avoidance function of a vehicle
Patent published on the 2026-04-22 in EP under Ref EP4729909 by TOYOTA MOTOR CO LTD [JP] (Sawano Takuro [jp], Koide Toshihiro [jp], Nagafuchi Yuhei [jp])
Abstract: A system includes: a first acquisition unit that acquires reliability of a first sensor that is a sensor mounted on a vehicle having a collision avoidance function of avoiding collision against an obstacle based on a distance between the vehicle and the obstacle, and detects the distance between the vehicle and the obstacle; a second acquisition unit that acquires reliability of a second sensor that is a sensor disposed outside the vehicle, and detects a distance between the vehicle and an inspe[...]
Our summary: The system monitors the reliability of two sensors related to collision avoidance. It compares the reliability of an internal sensor with an external inspection sensor. If the internal sensor s reliability is lower, it deactivates the collision avoidance function.

A case study for multiple chaotic mapping snake optimizer
Published on 2026-03-26 by @OXFORD
Abstract: AbstractIn recent years, chaos theory has been widely incorporated into metaheuristic optimization algorithms to enhance their search performance. However, for a given algorithm, there is still a lack of systematic and large-scale comparison regarding the effectiveness of different chaotic maps, and no clear consensus has yet been reached. To address this issue, this paper reviews 12 commonly used classical chaotic maps and summarizes three typical integration strategies of chaotic maps in bio-i[...]
Our summary: This study evaluates the effectiveness of 12 chaotic maps integrated into the snake optimizer. Simulation experiments reveal that performance improvements vary based on map type and problem characteristics. The tent chaotic map shows the most consistent enhancement, while a comparative analysis highlights the chaotic snake optimizer s advantages and limitations.
