A computer cart has segregated computer storage areas and adapter/cord management areas. This enables the adapters and cords to be stored in an orderly fashion and also prevents the cords and adapters from being accessed or removed from the cart when the computers are being accessed. In one embodiment, extensions of shelves on which the computers are stored extend through a dividing panel into a rear compartment of the cart to create AC adapter shelves for storage of the AC adapters. In another embodiment, the AC adapters are stored in bins in a separate compartment and cords from the AC adapters extend through a dividing panel to an area designed to hold the computers, to enable the computers to be plugged in to be charted while stored in the cart.

Computer cart

An electrical system for a computer cart enables power to be diverted between electrical channels within the cart using an intelligent round robin charging scheme. All power may be diverted to individual channels one at a time for short charging intervals. When a selected primary channel does not require all available power within the cart, excess power is provided to a secondary channel. All three channels may likewise share power if excess is available. Relays are used to allow power to be controlled to the individual channels. Current sensors on each channel sense an amount of current used by the channel. The output of the current sensor is digitized and integrated to determine how much current is being used by the channel. The current is used by the control to detect uncharged laptops and to selectively divert power between channels to optimize use of power within the computer cart.

A system for maintaining a large number of Handheld Electronic Devices is implemented as a carrying case having circuitry configured to connect to the Handheld Electronic Devices to enable the HEDs to be charged and synchronized. The carrying case has a central area configured to hold the circuitry for charging and synchronizing the HEDs, and a pair of divider structures on either side of the central area to hold the HEDs in a protective manner while stored in the carrying case. A grounded protective coating is applied to the interior of the carrying case to dissipate electromagnetic radiation generated by the circuitry and/or HEDs within the carrying case.

Carrying case

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.

Table leg and modesty panel assembly

An improved recessed computer monitor table that is capable of quickly and easily providing for height and angle adjustment of a computer monitor. The table comprises a top that has an opening adapted to receive the computer monitor and a support base attached to the top. Also, one or more recess side panels are adapted to mount to the top lower portion. Further, a rod adjuster assembly and one or more adjuster panels are provided. The one or more adjuster panels are adapted to adjustably mount to the one or more recess side panels and have one or more slots disposed on the one or more adjuster panels. The one or more slots are also adapted to receive the rod adjuster assembly. At least one recess top pan is provided that is pivotably mounted to the one or more adjuster panels at a first end and movably mounted to the one or more adjuster panels at a second end having the at least one slot.
