Abstract: A thin-film microelectrode array tailored for long-term, minimally invasive cortical recording or stimulation and method are provided. The microelectrode array includes a flexible element that is movable between a first contracted configuration and a second expanded configuration. An array of contacts is provided on the flexible element. The contacts are engagable with a cortical surface with the flexible element in the expanded configuration. A link operatively connects the array of contacts to a control module. The link is capable of transmitting at least one of cortical recordings and cortical stimulation signals thereon.

Abstract: A launch vehicle pedestal and an umbilical mast in which the pedestal includes a launch mount pedestal and four pedestal adapters. The launch mount pedestal includes a launch vehicle support base having an exhaust opening. Four legs extend downwardly from the support base and pedestal connecting means are secured to lower ends of each of the legs. The four pedestal adapters serve to secure the legs to existing launch vehicle support posts, the pedestal adapters each having adapter connecting means complementarily engageable with the pedestal connecting means. The umbilical mast comprises a plurality of round cylindrical segments connected by means of connectors at their ends. The connectors comprise radially extending flanges with circumferential holes in them. The mast further includes an access door and at least one opening in at least one of the segments for electrical cables and an air conditioning duct.

Abstract: The present invention utilizes a dual frequency data writing scheme. At a first frequency, flux transitions are achieved which result in large excursions of the information signal. In the preferred embodiment, the first frequency approximates the maximum frequency at which such excursions can occur. A second higher frequency is utilized to create the very small or no excursions. At this second higher frequency, a complex flux transition is not achieved. Therefore, there is little or no information signal. Information is represented by the presence or absence of excursions. In the preferred embodiment, the first frequency is approximately 33,000 flux changes per inch, and the second frequency is approximately 67,000 flux changes per inch. In order to detect data written by the present scheme, an adaptive, self-compensating scheme is utilized. The present invention utilizes an excursion detection scheme which is pattern and radii independent.
