Drawer for storing handheld electronic devices

A system for maintaining a large number of Handheld Electronic Devices (HEDs) includes a drawer having a divider structure configured to define compartments that are sized to hold the HEDs while the HEDs are stored in the drawer. A 20 port USB hub is provided in the drawer so that 20 HEDs may be connected to the USB hub while stored in the drawer. The USB hub allows the HEDs to be charged at a low rate while being synchronized with a computer and at a high rate when not being synchronized. The USB hub is designed using a tree structure of available USB hub chips to enable a larger number of USB ports. A microcontroller is provided to control the manner in which the computer is allowed to recognize the HEDs connected to the USB ports.

Electronic device storage cart

A computer cart is formed to have ventilation channels extending along its sides to enable computers to be ventilated while stored in the computer cart without requiring excessive machining of the side panels forming the cart. The cart includes a frame with an external skin formed of panels. The upper edges of the side panels are offset from an edge of a top panel so that a ventilation channel is formed between the top panel and the side panels. Optionally, the channel may also extend between the top panel and a side panel and between the top panel and a front panel including doors that allow access to an inside of the computer cart. A similar channel may be formed on the bottom. As air is heated by computers within the computer cart, the warm air will rise and exit the computer cart via the upper ventilation channel, while drawing in cooler air through the lower ventilation channel.
