Power saving device capable of automatically sensing standby current

Номер: US0010725521B2

The invention discloses a power saving device capable of automatically sensing standby current, which is used in a power device such as a power outlet or other power supply devices for giving the power device ability of electricity saving. When the power saving device normally works, a threshold current setting unit of a controlling and processing module is configured to automatically calculate a threshold current based on current signals sensed by a current detecting unit under different operation modes of at least one electrical device electrically connected to the power device. Moreover, when at least one standby current sensed from the electrical device is determined to be lower than the threshold current, the controlling and processing module immediately switches a switch unit to an open-circuit state, thereby causing the electrical device unable to receive electricity from the power device. Consequently, the power device exhibits the ability of power saving.

The information converting module receives an operation information from game controller and converts operation information into a subtitle information and saves it into subtitle buffering module. The video integrating module integrates coded video signal and subtitle information into a game video information with a specific video format. Therefore, requirements of time constraint and computing power can be reduced and operation load and cost of game recording apparatus can be lowered.

Access point in geographic routing system and controlling method thereof

Номер: EP3229502A1

An access point in a geographic routing system and a controlling method thereof are provided. The controlling method of the access point in the geographic routing includes the following steps. A traffic event packet is received by the access point. A back-off timer of the access point is set to be a first back-off time value. The first back-off time value is less than a second back-off time value of any on board unit (OBU) which receives the traffic event packet. The traffic event packet is broadcasted by the access point when the back-off timer is counted down to be zero.
