Abstract: The present invention is an interface adapter circuit that allows multiple types of 256k by 16 bit dynamic random access memories to be used by system manufacturers. The interface adapter circuit selects a type of outputs signal set to produce responsive to a mode selection signal. The circuit converts an input signal set including a column address strobe and low and high byte write signals into either a first output signal set, including one column address strobe and high and low byte write signals, or a second output signal set including a single write signal and high and low column address signals, responsive to the selection signal. The circuit includes a logic circuit for producing the signals and flip flops for holding the signals produced. The flip flops also synchronize other memory address, etc. signals with the signals produced by the adapter circuit. The interface adapter circuit can also convert write and column address timing signals and low and high byte write signals into the two sets responsive to a selection signal.

Abstract: This improved arterial blood monitoring system takes advantage of the basic statistical property of arterial blood that arterial blood contains a plurality of dominant absorbers, whose measured light absorption spectra appear as a constant over a short interval of time. The arterial blood characteristics to be measured are empirically related to the changes in the measured light transmission through the plurality of dominant absorbers as a function of the change in arterial blood volume at the probe site. Therefore, by measuring the transmitted light as it varies with arterial pulsation at selected wavelengths of light, the relative amount of these dominant absorbers in the arterial blood can noninvasively be determined. By selecting one wavelength of light around 1270nm, where water has a measurable extinction and a second wavelength at about 810nm, a wavelength that is substantially isobestic to oxygenated and reduced hemoglobin, a direct relationship between the transmitted intensities at these two wavelengths and the arterial hemoglobin concentration will exist and can be calculated. The use of a plurality of wavelengths of light enable the arterial blood monitoring system to concurrently measure a number of characteristics of arterial blood. By selecting wavelengths of light around 660nm, 940nm and 1270nm, the values of total hemoglobin and oxygen saturation of arterial blood can simultaneously be determined. In addition, oxygen content of arterial blood can be calculated from these values of total hemoglobin and oxygen saturation.

Abstract: A data receiver is described, in which a received signal is converted to digital form (1) and subsequently detected by means of a Viterbi processor (3). 
     In order that the analog-digital convertor (1) sample the incoming signal at the correct time, the sampling time is derived from an error signal, which is a metric for the difference between the expected symbol, and the symbol actually received. This is produced by a multiplier (4), a low-pass filter (5) and a controllable oscillator (6). In order to use information from precursors, an error signal, e(k-1), is used, which corresponds to a later time than does the tentative decision, â(k-2), of the present data symbol.
