Abstract
Abstract A camera or other device having a rechargeable battery is intended to be stored normally in a cavity of a charging-stand cradle in order to restore an electrical charge to the battery. The cradle includes a plug module that may be electrically connected to a standard alternating current (AC) outlet when the plug module is affixed to the cradle. Conversely, the plug module may be separated from the cradle to connect it to a remote AC outlet.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
182 words
A battery charging apparatus is characterized in that: a charging-stand cradle has a cavity configured for receiving a camera to support the camera in a battery charging position; electrical conductor means is located in at least one opening to said cavity for making electrical contact with corresponding conductor means of the camera to restore an electrical charge to a rechargeable battery inside the camera when the camera is supported in the cavity in the battery charging position; an electrical plug module having a pair of input and output prongs and a ground prong each configured to be inserted into a conventional alternating current outlet is connected to said electrical conductor means via an electrically conductive wire lead that is long enough to permit said plug module to be located remotely from said cradle; and securement means is located on said cradle for affixing said plug module removably to the cradle to permit said input, output and ground prongs to be inserted into a conventional alternating current outlet when the plug module is affixed to the cradle or is removed from the cradle.
Claim 2
Dependent Claim
182 words
A battery charging apparatus is characterized in that: a charging-stand cradle has a cavity configured for receiving a camera to support the camera in a battery charging position; electrical conductor means is located in at least one opening to said cavity for making electrical contact with corresponding conductor means of the camera to restore an electrical charge to a rechargeable battery inside the camera when the camera is supported in the cavity in the battery charging position; an electrical plug module having a pair of input and output prongs and a ground prong each configured to be inserted into a conventional alternating current outlet is connected to said electrical conductor means via an electrically conductive wire lead that is long enough to permit said plug module to be located remotely from said cradle; and securement means is located on said cradle for affixing said plug module removably to the cradle to permit said input, output and ground prongs to be inserted into a conventional alternating current outlet when the plug module is affixed to the cradle or is removed from the cradle.
Claim 3
Dependent Claim
37 words
A battery charging apparatus as recited in claim 2, wherein said cradle includes support means about which said wire lead can be wrapped to store the wire lead when said plug module is affixed to said cradle.
Claim 4
Dependent Claim
81 words
A battery charging apparatus as recited in claim 1, wherein said securement means includes integral means for affixing said plug module to said cradle selectively in respective orientations in which said ground prong is located below said input and output prongs or the ground prong is located above the input and output prongs to permit the plug module to be plugged into a conventional alternating current outlet when the plug module is affixed to the cradle in either of the orientations.
Claim 5
Dependent Claim
63 words
A battery charging apparatus as recited in claim 1, wherein said securement means includes integral means for affixing said plug module to said cradle selectively in a storage position in which said input, output and ground prongs face inwardly with respect to the cradle and a use position in which the input, output and ground prongs face outwardly with respect to the cradle.
Claim 6
Dependent Claim
36 words
A battery charging apparatus as recited in claim 4, wherein said cradle has a cavity for receiving said input, output and ground prongs when said plug module is affixed to the cradle in the storage position.
Claim 7
Dependent Claim
160 words
A battery charging apparatus is characterized in that: a charging-stand cradle is configured for receiving a battery powered device to support the device in a battery charging position; electrical conductor means is located on said cradle for making electrical contact with corresponding conductor means of the battery powered device to restore an electrical charge to a rechargeable battery inside the device when the device is supported in the battery charging position; an electrical plug module adapted to be inserted into a conventional alternating current outlet is connected to said electrical conductor means via an electrically conductive wire lead that is long enough to permit said plug module to be located remotely from said cradle; and securement means is located on said cradle for affixing said plug module removably to the cradle to permit the plug module to be inserted into a conventional alternating current outlet when the plug module is affixed to the cradle or is removed from the cradle.
Claim 8
Dependent Claim
160 words
A battery charging apparatus is characterized in that: a charging-stand cradle is configured for receiving a battery powered device to support the device in a battery charging position; electrical conductor means is located on said cradle for making electrical contact with corresponding conductor means of the battery powered device to restore an electrical charge to a rechargeable battery inside the device when the device is supported in the battery charging position; an electrical plug module adapted to be inserted into a conventional alternating current outlet is connected to said electrical conductor means via an electrically conductive wire lead that is long enough to permit said plug module to be located remotely from said cradle; and securement means is located on said cradle for affixing said plug module removably to the cradle to permit the plug module to be inserted into a conventional alternating current outlet when the plug module is affixed to the cradle or is removed from the cradle.
Claim 9
Dependent Claim
62 words
A battery charging apparatus as recited in claim 6, wherein said cradle includes securement means for affixing said plug module to the cradle selectively in a storage position in which said input, output and ground prongs face inwardly with respect to the cradle and a use position in which the input, output and ground prongs face outwardly with respect to the cradle.
Claim 10
Dependent Claim
61 words
A battery charging apparatus as recited in claim 6, further characterized in that: respective indicator means are connected to said conductor means of said charging-stand cradle for providing perceptable indications when the battery powered device is supported in the cavity in the battery charging position that the particular battery inside the device is a rechargeable one or is a non-rechargeable one.
