A light fixture removably attachable to a stationary socket includes a lamp socket mounted for receiving a lamp and a connector which is electrically engageable with such stationary socket. The connector is attached in spaced relationship to the lamp socket and is electrically connected thereto. The light fixture may include a housing having the lamp socket mounted therein with the connector attached to the housing in one of a rigid, hinged and swivel manner. The light fixture is advantageous for converting a unidirectional recessed light fixture into a multidirectional light fixture.

A scanning AC hall microscope and a method which measures the domain pattern of magnetic materials, such as magnetic storage media, by measuring the oscillatory motion of a domain boundary under the influence of an external applied AC magnetic field, which allows a differentiation between domains which are immobile and domains which are mobile.

A method for reducing imprint in a ferroelectric device which includes the steps of: applying a signal having a bipolar pulse shape for a predetermined time to the ferroelectric device; and decreasing the signal amplitude gradually in predetermined intervals of time and amplitude. Preferably, the bipolar shape signal is a sinusoidal wave, a square wave, or a sawtooth wave and the ferroelectric device is a capacitor of a memory cell in a computer. Also provided is an apparatus for reducing imprint in a ferroelectric device.
