Appl. No.:

09/648440

Inventors:

Maria Angel - Irvine CA
Anthony Roberts - Huntington Beach CA
Jeffrey G. Whitelaw - Corona CA

Assignee:

Mitsubishi Digital Electronics America, Inc. - Irvine CA

International Classification:

H04N 564

US Classification:

348744, 348787, 348789

Abstract:

A system and method that facilitates the transformation of PTVs, when in the âOFFâ mode, into aesthetically pleasing decorative furniture. The PTV preferably includes a primary and a secondary projection system. The secondary projection system preferably comprises a projection unit optically coupled to the screen of the PTV and an auxiliary image source coupled to the projection unit. Preferably, the program logic of the PTV directs the projection of an image from the secondary projection unit onto the screen when the PTV is in the âOFFâ mode.

Abstract:

A self-adjusting chain tensioner is configured to adjust tension of a chain that connects a self-ratcheting tension drive pulley and a bearing pulley in response to ambient temperature. The self-adjusting chain tensioner has a dynamic block immediately adjacent to the chain with two pair of vertical plate guides. A horizontal plate is attached to the dynamic block with an inner spring and an outer spring. Vertical plates attached to the horizontal plate assists in movement of the dynamic block in a vertical direction. A bracket attached to the horizontal plate attaches the self-adjusting chain tensioner to a motorcycle. The inner spring and the outer spring can expand or contract in response to changes in the ambient temperature which adjusts a position of the dynamic block and thus keeps consistent tension on the chain which reduces wear on bearings in the bearing pulley.
