Abstract: An extendible mirror bracket housing is fastened onto the rear view mirror in the interior of a motor vehicle. The bracket housing slidably carries a bracket within an elongated channel formed in the housing. An extension mirror is pivotably fastened by a hinge to the bracket and may be extracted from the channel. Stop members preclude extraction of the bracket member from the channel. An additional extension mirror may be provided at the rear of the first mentioned extension mirror.

Abstract: A memory module containing addressable memory devices, and the circuits necessary to address and drive these devices, is configured so that a trade-off between memory size and word length can be made by rewiring the backplane. Thus, a single memory module design can be used for a variety of computer memory applications. This is accomplished by incorporating on the module a complete set of addressing and signal driving circuits, and allowing for the control of these module components through a system of control lines wired through the backplane.
