Abstract:
1. A case for a tablet computer, comprising: a base; a cover pivotally attached to the base; an interface comprising controller coupleable to a removable storage device that is configured to allow the tablet computer to communicate with the removable storage device using a communication protocol not supported by the tablet computer, the interface further comprising a current sensor coupled to a first connector that is coupleable to a host, a battery charger, and a switch that in a first position selectively couples the controller and the battery charger to a second connector that is coupleable to the tablet computer and that in a second position couples the current sensor and the first connector to the second connector; wherein the cover is configured to store one or more spare storage devices while the one or more spare storage devices are not coupled for communication with the interface; wherein the current sensor is configured to receive current from the host and to send substantially all of the current received from the host to the tablet computer in response to determining that the current received from the host is less than or equal to a certain value when the switch is in the second position and to concurrently send a first portion of the current received from the host to the tablet computer and a second portion of the current received from the host to the battery charger in response to determining that the current received from the host is greater than the certain value when the switch is in the second position; wherein when the switch is in the first position, the battery charger is coupled to receive current from the tablet computer.
