Definitions

• the UPM includes a single wire, self configurable bus, for example, the single wire is BUS3.
• the self configuration is the result of the protocol definition.
• the protocol is one way for the bus to self configure when various items (cables, UPMs, etc) are plugged/unplugged or batteries are full, etc.
• FIG. 5 shows a top view and a side-end view of a UPM according to certain
• FIG. 7 shows a functional diagram of a stack of three UPMs connected to a
• FIG. 20 shows a side view of a two-piece housing that integrates with a portable device and a UPM attached thereto, according to one or more embodiments.
• the stack of UPMs 10 may also be connected to a power source such as a wall outlet, or a laptop or desktop computer.
• a power-input cable 16 connects a power source to a charge input port of one of the UPMs in the stack 10.
• a stack of UPMs such as the stack 10 is connected to a power source using a power-input cable
• the stack of UPMs is collectively charged as described below.
• Suitable power input cables include, but are not limited to, USB power cables and A/C plug cables.
• the stack of UPMs may be connected to the portable device and to an external power source simultaneously. This allows the portable device 1 1 and the UPMs 10 to be charged at the same time.
• connection assembly 21 can include a wide variety of connectors that may be used for this purpose, including but not limited to magnetic connections, VelcroTM connectors, hooks, studs, latches, dovetails, snaps, elastics, etc..
• the connection method may also use mechanical slots and hooks as described below with reference to Figures 14, 15, and 16A-C.
• the replacement battery door shown in FIG. 14 and FIG. 15 also has the advantage of maintaining a sleek profile when a UPM is not attached to the slots on the back of the door.
• the back of the replacement battery door is substantially flat, as can be seen in FIG. 28.
• FIG. 4 shows the front side of the case 20 that is illustrated in FIG. 2.
• a user stacks one UPM on top of another by inserting the hooks of one UPM into the hook-receivers of another, and then sliding laterally, locking the two UPMs in place.
• FIG. 6 shows the process of stacking two UPMs together.
• the hooks 53 of the upper UPM are inserted into the hook-receivers 54 of the lower UPM.
• the upper UPM has been moved forward relative to the lower UPM, securing the hooks in place.
• Hook 53 engages with a lip of hook-receiver 54 to retain the UPM in locked position.
• the IMI bus connects UPMs to other UPMs, but also connects UPMs to portable devices such as smartphones In this way, all devices connected to a stack of UPMs (including the UPMs themselves) can be considered to be connected to a single IMI bus.
• FIG. 7 shows a functional diagram of a stack of three UPMs 70 71 72 connected to a smartphone 73 via an IMI bus 74.
• the stack of three UPMs is used to power the smartphone, which has only 10% charge remaining.
• Each of the UPMs in the stack is only partially charged.
• UPM 70 has 30% charge remaining;
• UPM 71 has 23% charge remaining;
• UPM 72 has 25% charge remaining.
• FIG. 8 shows a power hub 800 created from two UPMs, in which one UPM charges the other.
• UPMs can be charged from external AC power source 820 or even from portable electronic devices 810.
• the UPM can be used as a stand alone power hub to charge other devices.

• the UPM can be used as a stand alone power hub to charge other devices.
• An exemplary UPM has the following features (note that this list applies to certain embodiments only and is not intended to be exhaustive):
• the IMI bus can include three power/signal pins, such as BUS1, a 5 V power bus, BUS2, power and signal ground, and BUS3, control path.
• the UPM has two IMI interfaces, a "leftmost" interface (the female connector) and “rightmost” interface (the male connector), and the BUS1 and BUS2 are hard connected between the left and right most interfaces and the BUS3 goes through a local microprocessor.
• a Skin only has the "leftmost" interface.
• the device taking charge decides to stop taking charge (for example, the device is full).
