Abstract: The device includes, in a housing, an actuator electrically connected to a battery for charging a portable item such as a mobile terminal. For a rotating actuator comprising a first member submitted to an oscillatory motion, for example a walker carrying the housing, and a second member making up at least partially a mass part, the mass part is able to oscillate around the axle of the armature with respect to the first member. A servo control system can control the actuator sometimes as a motor supplied by the battery or by allowing the mass part to move freely, sometimes as a generator charging the battery, by slaving the motion speed of the mass part to the acceleration of the oscillatory motion of the first member. This enables to recover as much electric power as possible from the walker.

Abstract: A collision avoidance method for transmitting data from multiple wireless tire condition sensors on a vehicle is executed by each wireless tire condition sensor having a unique ID and multiple different wake-up times. After the sensor is operated to sense data, the method has steps of reading the ID and computing a determination value with the ID and a variable, selecting one of the wake-up times according to the determination result, and after the selected wake-up time expires, transmitting the sensed data. As the selected wake-up times of the sensors differ from one another, data collision at the receiving end arising from data transmission from the sensors can be avoided. Additionally, besides the wake-up time, a time gap between data transmitted twice consecutively from each sensor can be employed to achieve data collision avoidance.

On detection of a modification of the routing topology, at the level of a first node connected by a link to at least one second node, a timer value associated with the second node is determined.

The timer value is provided by an increasing function taking as parameter the metric associated with said link connecting the first node to the second node, so that the larger the metric, the larger the timer value.
