The Digital Home TheaterTM
product consists of a dual front/rear projector. This projector
allows the consumer the option to view both television and pre-recorded
films on a large (60 inch or greater) screen or on the wall. Consumers may
use this as a computer monitor with 800x600 SVGA. The projector is
easily
removed from its cabinet and can be transported out of the home or mounted
upon a wall/ceiling. In addition, the system comes with a remote control,
power cord, hookups for other devices (VCR's, Laser disc players, etc.),
and manuals.
Mechanical Drawings of the Digital Home TheaterTM
The overall time for the average consumer to assemble the complete system
is no more than 30 minutes. No special tools are required. All assembly
and structural hardware is kept to a minimum. The overall weight does
not exceed 200 lbs. The complete system is contained within three
containers.
Rear Projection Cabinet
The rear projection cabinet is broken into two assemblies, the upper and
lower assembly. It is attached with four turn fasteners.
Upper Cabinet Assembly
The upper cabinet consists of the collapsible viewing screen and mirror. The
consumer opens the sub-assembly into an "A" frame shape. This is
accomplished with a collapsible back. The "A" frame prevents the user
access to the front of the mirror's surface and the rear of the viewing screen.
Lower Cabinet Assembly
The lower sub-assembly consists of the base plate and pedestal support
structure.
The base plate and pedestal prevents tipping of the unit when the projector is
inserted and withdrawn.
Pedestal
The pedestal holds the drawer for the projector and contains
an internal non-removable docking station.
The docking
station allows the users to insert the projector assembly.
Connections for all power, video, audio, and SVGA cables are in the rear.
The customer will install the wide angle rear
projection lens before placing the projector into the drawer's docking
station.
The drawer stores the front projection lens
and the external docking station.
The docking station routes all cabling/connections so that they are not
accessible to the consumer. Any cabling within the docking station will cause
no signal loss between the projector and the rear connections. All manual
controls such as Power ON/OFF, Volume, and Channel are located on the
projector itself and are accessible to the user from the front of the cabinet.
The base plate consists of stamped steel which acts as a counter-balance
to prevent tipping of the unit when the projector is removed and inserted. It
contains 4 turn fasteners for the upper cabinet assembly to mount to. The
bottom of the base
plate has six casters for ease in moving.
Docking Station
The Docking Station passes all of the Video, Audio, SVGA, and Power
signals to the projector. The Docking Station
quickly connects and disconnects to the projector. It
will not degrade any of the Audio or Video signals. A tuner is located in
the docking station.
Electrical Connections
The pedestal/docking station and external/docking station contains the
following electronic connections:
Connector Type | I/O | Name |
RCA Jack | I | Audio Right |
RCA Jack | I | Audio Left |

Projector
The projector consists of a light engine and electronics contained within an
enclosure plus two lens systems. The projector has the capability of operating
as a stand-alone unit for front projection or within a rear projection cabinet.
In order to accomplish this, two lens systems have been developed, i.e., one
for the front and one for the rear operating mode.
