Bi-directional power control
First Claim
1. An electrical circuit for bi-directional power control between two devices, comprising:
- a first battery-operated device, comprising;
a first battery operative to provide a source of power to the first device;
a first power management subsystem connected to said first battery, operative to power on components of the first device in response to occurrence of an event to wake up the first device; and
a first on/off button operative to generate an event to wake up the first device;
a second battery-operated device, comprising;
a second battery operative to provide a source of power to the second device;
a second power management subsystem connected to said second battery, operative to power on components of the second device in response to occurrence of an event to wake up the second device;
a second on/off button operative to generate an event to wake up the second device; and
a switch operative to automatically generate an event to wake up the first device, in response to said second on/off button generating an event to wake up the second device; and
circuitry comprising a single connection line inter-connecting said first power management subsystem, said first on/off button, said second power management subsystem, said second on/off button, and said switch.

Abstract
An electrical circuit for bi-directional power control between two devices, including a first battery-operated device, including a first battery for providing a source of power to the first battery-operated device, a first power management subsystem connected to the first battery, to power on and power off components of the first battery-operated device in response to a first wakeup event, WE1, and a first on/off button for generating WE1, a second battery-operated device, including a second battery for providing a source of power to the second battery-operated device, a second power management subsystem connected to the second battery, to power on and power off components of the second battery-operated device in response to a second wakeup event WE2, a second on/off button for generating WE2, and a switch for generating WE1 simultaneously when the second on/off button generates WE2, and circuitry including a single connection inter-connecting the first power management subsystem, the first on/off button, the second power management subsystem, the second on/off button, and the switch for generating WE1.

5. An electrical circuit for bi-directional power control between two devices, comprising:
-
a mobile communication card; an electronic device that connects to said communication card, the electronic device being either (i) a host device that operates independently of said communication card and also interoperates with said communication card, or (ii) a jacket for said communication card, wherein the jacket is a passive device that does not operate independently of said communication card; and circuitry connecting said mobile communication card with said electronic device, comprising; a card on/off button operative to power said mobile communication card on and off; a device on/off button operative to power said electronic device on and off; and a switch, wherein said circuitry uses a single connection line connecting said communication card, said electronic device, said card on/off button, said device on/off button, and said switch, to enable (i) said card on/off button to power said communication card on and off, (ii) said device on/off button to power said electronic device on and off, and (iii) said electronic device to automatically power said communication card on and off using said switch, in response to said electronic device being respectively powered on and off. - View Dependent Claims (6, 7)
