Abstract
Abstract This invention relates to office workstations, and particularly to a revolutionary electronic office workstation combining user access to communication, entertainment, record keeping, computation, environmental control, writing and miscellaneous functions. The workstation acts as a desk when viewscreen and keyboard are retracted and covered by a built-in retractable cover. When directed by embedded computer or manually, the workstation repositions the viewscreen to a preselected operational attitude. The operational attitude may vary between horizontal and slightly past vertical. The workstation includes embedded appliances such as copier, printer, facsimile, personal computer and future optional appliance connections, with central control unit and buses for power, data, communications, control and other functions. Embedded appliances do not require individual covers or individual power supplies, and accordingly there is no maze of cables in view. Interconnecting buses make internal cable connections simple, inexpensive and straightforward. The workstation comprises a fuselage unit which provides shared support for appliances, from a universal power coverter and a control microprocessor. The fuselage also provides gravity support for wings and appended appliance modules which are supported physically and electrically. There is a lock system for activating a selection of appliances authorized for the particular user. There is a workstation control program and provision for a user personalization program.
