Abstract: A mobile office system provides a portable, convenient, and efficient framework for setting up communication devices, establishing connectivity, and delivering interactive presentations. The mobile office system includes a portable component carrier. Inside the portable component carrier are component placement structures that define placement locations at which the specific components of the mobile office may be placed, stored, and secured. As one example, the component placement structures may define slots configured to securely hold tablet computers in place during movement of the portable component carrier.

Abstract: A programmed microcontroller based sump pump system includes multiple pumps that can be employed with one as a primary pump and one as a back-up, or can be employed in combination to increase the discharge rate. The microcontroller monitors the back-up battery condition, and computes and displays the battery life; monitors the system for clogs or vapor locks in the discharge piping; switches to an emergency periodic pumping mode of operation, when needed; and notifies the user by phone or e-mail of a system malfunction.

Abstract: Generally there is provided a ROM memory arranged to be inserted in place of a pre-existing ROM on the microprocessor based circuit board under test, wherein the ROM contains specific test sequences programmed therein. The test apparatus further includes a microprocessor control, a keypad, a display and an interface. On start up the circuit under test runs programs stored in the inserted ROM and outputs on the data bus information relative to the results. During some tests the circuit is held in a wait state to allow probing of the circuit under test for logic errors. In an operator programmed test mode the operator may cause the system to read and write data in response to entries from the keypad.
