Abstract

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for performing tests on mobile devices. In one aspect, a power distribution system includes a set of mobile devices and a computer that manages the execution of a test using the set of mobile devices. The computer can include one or more data communication ports. The system can also include one or more Universal Serial Bus (USB) hubs connected to the mobile devices using USB cables. Each mobile device can be connected to one of the one or more USB hubs. The system can also include one or more USB charging hubs connected between each data communication port of the computer and at least one of the one or more USB hubs. The system can also include a power supply connected between a power source and each of the one or more USB hubs.

First claim

What is claimed is:

1 . A power distribution system, comprising:
a set of mobile devices; a computer that manages the execution of a test using the set of mobile devices, the computer comprising one or more data communication ports; one or more Universal Serial Bus (USB) hubs connected to the mobile devices using USB cables, each mobile device being connected to one of the one or more USB hubs; one or more USB charging hubs connected between each data communication port of the computer and at least one of the one or more USB hubs, each USB charging hub providing power to the at least one USB hub that enables data communication between the computer and the mobile devices connected to the at least one USB hub; and a power supply connected between a power source and each of the one or more USB hubs, the power supply providing power for each of the one or more USB hubs and the mobile devices connected to each of the one or more USB hubs.

2 . The system of claim 1 , wherein the power supply is a customized power supply selected based on power usage of the set of mobile devices.

3 . The system of claim 1 , wherein the set of mobile devices comprises at least one of (i) a set of smartphones or (ii) a set of tablet computing devices.

4 . The system of claim 1 , wherein the USB charging hub and the power supply stabilizes power to the set of mobile devices.

5 . The system of claim 1 , wherein the power supply provides sufficient power to charge batteries of the set of mobile devices during testing.

6 . The system of claim 1 , wherein the one or more data communication ports comprises at least one USB Peripheral Component Interconnect (PCI) card.

7 . The system of claim 1 , wherein the set of mobile devices, the computer, the one or more USB hubs, the USB charging hub, and the power supply are mounted in a tray of a server rack.

8 . The system of claim 7 , further comprising a set of lights that indicate errors associated with the mobile devices.

9 . A method performed by data processing apparatus, the method comprising:
receiving data specifying a test to be performed using mobile devices; receiving criteria for the test; selecting one or more test groups based on at least on one of (i) the test or (ii) the criteria for the test, each test group including one or more mobile devices; performing the test using the selected one or more test groups; and providing data specifying results of the test.
