Abstract
A battery cell phone combination for use in a cell phone or other electronic device having a case or housing is provided. The battery cell phone combination has a primary battery and a secondary battery each being shaped so as to be able to be received in the case. When the primary battery is drained the user can enable the secondary battery in a rapid manner and for a fee or for free. The primary and secondary batteries are isolated from each other such that there is no current seepage between the two. The cell phone is continuously powered when switching from the primary battery to the secondary battery such that calls are not dropped during the switching process.
Claims15
A combination cell phone comprising:
- a cell phone having a cell phone housing;
- a battery assembly disposed in the cell phone housing, and the battery assembly having a primary battery and a secondary battery and wherein the primary and secondary batteries are isolated from one another and each is for powering a load derived from the cell phone;
- a circuit disposed in the cell phone housing and a switch is operatively associated with the cell phone and the primary and secondary batteries such that either the primary or secondary battery is capable of powering the cell phone;
- the circuit includes a delay logic circuit operatively associated with a switch allowing for uninterrupted cell phone operation when switching from the primary battery to the secondary battery;
- the circuit includes a primary battery passgate component for selecting or isolating the primary battery from a load;
- the circuit includes a secondary battery passgate component for selecting or isolating the secondary battery from the load;
- and,
- wherein the primary passgate component includes a first NFET passgate, a first PFET passgate, a second NFET passgate and second PFET passgate each being operatively associated with the delay logic circuit and for allowing either the selection or the isolation of the load from the primary battery.
A method of providing power to a device comprising the acts of:
- providing a battery assembly having primary and secondary batteries and isolating the primary and secondary batteries from one another;
- providing a switch to select either the primary battery or the secondary battery;
- providing the device with a screen display and indicating on the screen display the amount of charge remaining in the primary and secondary batteries on the screen display;
- providing the device with a circuit with a delay logic circuit that is operatively associated with the first and second batteries such the device is continuously powered when the switch is moved from the primary battery position to the secondary battery position;
- and,
- further including providing a cell phone service provider company and providing the cell phone service provider with control over the switch and allowing the cell phone service provider company to charge a fee when the switch is moved from the primary battery position to the secondary battery position.
A combination electronic device comprising:
- a electronic device having a housing;
- a battery assembly disposed in the housing, and the battery assembly having a primary battery and a secondary battery and wherein the primary and secondary batteries are isolated from one another and each is for powering a load derived from the electronic device;
- a circuit disposed in the housing and a switch is operatively associated with the electronic device and the primary and secondary batteries such that either the primary or secondary battery is capable of powering the electronic device;
- the circuit includes a delay logic circuit operatively associated with a switch allowing for uninterrupted electronic device operation when switching from the primary battery to the secondary battery;
- the circuit includes a primary battery passgate component for selecting or isolating the primary battery from a load;
- the circuit includes a secondary battery passgate component for selecting or isolating the secondary battery from the load;
- and,
- wherein the primary passgate component includes a first NFET passgate, a first PFET passgate, a second NFET passgate and second PFET passgate each being operatively associated with the delay logic circuit and for allowing either the selection or the isolation of the load from the primary battery.
