`ABSTRACT
`A case battery system is provided. The case battery system
`comprises the case battery, the connector adaptor and the
`dock. The case battery configured to enclose and hold at least
`part of a personal electronic device. The personal electronic
`device may be connected to the connector adaptor, O
`installed on the dock to be charged or communicate among
`themselves and with other electronic devices. The top holding
`portion is configured to hold the top and partial lateral part of
`the personal electronic device with holes. The rear plate por
`tion comprises the charging portion and the first circuit por
`tion, or the rear plate portion can be a regular plate without the
`charging portion and the first circuit portion. The top holding
`portion, the rear plate portion and the bottom holding portion
`can be assembled sliding the longitudinal rails to the longi
`tudinal rail recesses to enclose a personal electronic device.

`
`BACKGROUND OF THE INVENTION
`
`10
`
`The present invention relates to a case battery system
`which extends the usage time of a personal electronic device.
`More particularly, this invention relates to a case battery with
`storage that provides more electrical power and protection of
`a personal electronic device. Furthermore, the present inven- 15
`tion provides the case battery an ability to be engaged on the
`dock even when a personal electronic device is placed in it so
`as to be charged and communicate between a personal elec
`tronic device and components of the case battery system, an
`2O
`external electronic device.
`“Portable' is one of the keywords which defines the era of
`information technology. Computing power had been an
`obstacle to making the technology portable for a long time.
`Considering the first computer, it would be easy to understand
`the situation. With the advent of the transistors and integrated 25
`circuit, however, computing power can be crammed in a
`really small space. Locating the heart of a computer inside the
`computer or even on a mother board is not easy, actually
`challenging to a layman. Once the computing power became
`possible for portability, it took a very short time to recognize 30
`the hard fact that the power source of a battery and the
`memory capacity are the serious problems. This is much
`harder to solve than the CPU problem.
`Since the 1990s, portable electronic devices such as cel
`lular phones, MP3 players, camcorders, digital cameras, etc.,
`have become indispensable to every one. The portable elec
`tronic devices need to be charged very frequently such that the
`usage is critically limited.
`Also, because functions of portable electronic devices are
`limited, a variety of convenient Supplementary functions are
`in demand to fulfil users’ needs.
`Accordingly, a need for a case battery system for a personal
`electronic device or a portable personal electronic device has
`been present for a long time. This invention is directed to
`solve these problems and satisfy the long-felt need.

`
`SUMMARY OF THE INVENTION
`
`50
`
`The present invention solves the disadvantages of the prior
`art.
`An objective of the invention is to provide a case battery
`system for a personal electronic device. The case battery
`system includes a case battery, a connector adaptor, and a
`dock.
`Another objective of the invention is to provide a case
`battery for a personal electronic device which can extend the
`usage time of the personal electronic device.
`Still another objective of the invention is to provide a case
`battery for a personal electronic device which provides a 60
`connector adaptor and a dock for charging the personal elec
`tronic device and a battery in the case battery. Also, the
`connector adaptor and the dock may provide a connection to
`other electronic device Such as computer or cellphone.
`The invention provides a case battery for a personal elec- 65
`tronic device. The case battery includes a bottom holding
`portion, a rear plate portion, a top holding portion.
`

`dock and communications between other components of the
`case battery, a personal electronic device and an external
`electronic device.
`The dock may include a holding cup, a plurality of spring
`connectors, a plurality of locks, a plurality of holes, plurality
`of release buttons, a multi-purpose receptacle, a FM/AM
`radio, antennae, a plurality of controllers, a plurality of dis
`plays, a charging indicator, a plurality of speakers, a micro
`phone, an optical sensor and an inactivation off Switch.
`The holding cup may be configured to accept and engage at
`least part of the bottom holding portion.
`The spring connectors may be configured to connect the
`connector receptacle plates of the bottom holding portion
`when disposed at a bottom of the holding cup. The spring
`connector of the dock may be configured to be connected to
`the multi-purpose receptacle of the dock which further con
`nects to an external electronic device via a USB connector or
`other types of connectors.
`The plurality of locks may be configured to lock the bottom
`holding portion in place.
`The release button may be configured to release the bottom
`holding portion from the plurality of locks.
`The connector receptacle plates may be configured to elec
`trically connect the first connector to an external device.
`The multi-purpose connector receptacle may be configured
`to accept a multi-purpose connector from the external elec
`tronic device.
`The charging indicator may be configured to monitor the
`charging status of the charging portion and the battery of the
`personal electronic device.
`The rear plate portion including charging and circuit por
`tion may be replaceable, and the rear plate portion may have
`a predetermined thickness according to a capacity of the
`charging portion and the complexity of the first circuit por
`tion. Then the holding cup may be adjustable or replaceable
`according to the various thickness and size of the case battery.
`The bottom holding portion may further include case bat
`tery speakers connected to the personal electronic device and
`an deactivation switch. The dock may further include a bump
`configured to press the deactivation switch when the bottom
`holding portion is installed on the dock so as to deactivate the
`case battery speakers.
`The top holding portion may include a third mechanical
`fastener, and the rear plate portion may include a fourth
`mechanical fastener corresponding to the third mechanical
`fastener. The top holding portion and the rear plate portion
`may be attached and locked to each other by the third and
`fourth mechanical fasteners.
`The case battery may further include a connector adaptor
`configured to be attached to or detached from the bottom
`holding portion, and the connector adaptor may comprise a
`plurality of locks configured to lock the connector adapter to
`the bottom holding portion, a release button configured to
`release the connector adaptor from the bottom holding por
`tion, and a multi-purpose receptacle. The bottom holding
`portion may further comprise a guide recess and a locking
`recess at a lower part Such that the connector adapter is guided
`to be fitted exactly to the bottom holding portion in order to
`connect the connector receptacle plates and the spring con
`nectOrS.
`The connector adaptor may include a charging status of the
`charging portion and the battery of the electronic device.
`The personal electronic device may comprise a portable
`game machine, a cellular phone, a PDA, a palmtop, a MP3
`player, a camcorder, a digital camera or a GPS.
`The advantages of the present invention are: (1) the case
`battery can extend the usage time of the personal electronic
