Abstract: A transducer housing stabilization device for supporting a transcranial Doppler transducer against a temporal bone of a head. The device includes a generally planar, rigid member having an opening therein. The member has perforations therein for engaging an adhesive to secure the planar member adjacent to the temporal bone of the head. A transducer housing on the member receives the transducer thereby positioning the transducer in place adjacent the temporal bone of the head.

Abstract: A method and apparatus are disclosed for producing an image made up of marks having varying sizes, densities and/or shapes on an imaging media. The image is generated in response to image data defining the image to be produced received by an input scanner or other input device. The image data is processed and then used to address at least one amplitude and/or pulse width modulation table to, in turn, generate amplitude and pulse width signals which controls a writing device. Marks are therefore written onto the media, such marks having varying sizes, densities and/or shapes for forming the completed image.
