Embodiment Construction

[0049]In general terms, the present disclosure relates to a system including a power generating device, a system including a power generating device positioned inside a tire of a vehicle (such as a tire pressure monitoring system), and a method for conserving power within the system installed in the device. method. More specifically, a power generating device in the form of an energy harvesting device to convert ambient energy (eg motion, rotation, vibration) into electrical energy in response to motion of the device. This electrical energy is used to power switching elements, which in turn are used to power up the system from a full power down mode. When the energy harvesting device is no longer producing power (ie, the device is no longer in motion) after a predefined period, the switching element is cut off from the current, which in turn removes power from the system, returning the system to a full power down mode. Thus, the system is only in power-on mode when needed, th...

Abstract

A system in a device includes an electronic module configured to perform a function associated with the device, a power generation apparatus for generating electrical energy in response to motion of the device, and a switch element interposed between the electronic module and the power generation device. The switch element switches from a first state to a second state when the power generation apparatus generates the electrical energy. The electronic module is in a powered-off mode in which a power storage device is disconnected from the electronic module whenever the switch element is in thefirst state. The electronic module is switched to a powered-on mode in which the power storage device is in electrically connected to the electronic module whenever the switch element is in the secondstate.

Description

technical field [0001] The present invention generally relates to battery powered systems. More specifically, the present invention relates to conserving power from batteries in battery powered systems. Background technique [0002] A wide variety of electronic devices are powered by non-rechargeable and rechargeable batteries. Low power consumption is important to conserve and extend the life of the batteries in such devices. Techniques for conserving battery power involve placing electronic devices in sleep mode. A sleep mode is a low power mode of an electronic device in which the device suspends power delivery to systems that are not needed. However, some battery power is consumed while sleeping in order to power some systems and to be able to respond to wake events. Thus, periodic waking up and returning to sleep mode can drain the battery and shorten its useful life. As the usage of battery-powered electronic devices increases, techniques for preventing unnecessar...
