A method and device for audiological screening of infants and newborns by generating one or more stimuli with an audiologic screening device having acoustic transmitters in each ear canal to generate otoacoustic emissions, collecting and transmitting the otoacoustic emissions signals and brain stem response signals, analyzing the same, and transmitting the data to a remote central computer server via a built-in or attached modem or global information network for further analysis and storage.

An audiological screening and testing method for newborns and infants employing audiological screening via statistical phase analysis of otoacoustic emissions in response to acoustic stimuli.

Audiological screening method and apparatus

An audiological screening and testing method for newborns and infants employing audiological screening via statistical phase analysis of otoacoustic emissions in response to acoustic stimili.

Contact interconnect levels for integrated circuit with a semiconductor substrate consisting of silicon in which and on which components forming the circuit are produced, are composed essentially of an aluminum/silicon/titanium alloy having a proportion of about 1 through 2% by weight silicon and a titanium content of less than about 0.5% by weight. The reliability and loadability of electrical interconnects for VLSI systems is increased by utilization of this metallization.

Integrated semiconductor circuits with contact interconnect levels

Solar cells having a semiconductor body composed of amorphous silicon which is applied to a substrate coated at least at one surface thereof with aluminum, functioning as a back contact. Recrystallization is prevented by alloying silicon or silicon/titanium into the aluminum layer so that the amounts of silicon within the alloy is, in preferred embodiments, about 1.3% by weight and, with the presence of 0.1% by weight titanium, is at about 1.2% by weight.
