Title: Integrated circuit containing bi-polar and complementary mos transistors on a common substrate and method for the manufacture thereof
Inventor: WINNERL JOSEF
IPC: H01L21/82
Filed: 1987-07-03
Granted: 1992-11-24
Abstract: ABSTRACT OF THE DISCLOSURE             An integrated circuit containing bipolar and complementary MOS transistors wherein the base and emitter terminals of the bipolar transistor, as well as the gate electrodes of the MOS transistors, are composed of a silicide or of a double layer polysilicon silicide.  The base and emitter terminals, as well as the gate electrodes, are arranged in one level of the circuit and there p+ doping or, respectively, n+ doping proceeds by ion implantation in the manufacture of the source/drain zones of the MOS transistors.  As a result of the alignment independent spacing between the emitter and the base contact, the base series resistance is kept low and reduction of the space requirement is achieved.  Smaller emitter widths are possible by employing the polycide or silicide as diffusion source and as the terminal for the emitter.   The size of the since the silicide terminals can be contacted via the field oxide.  The integrated semiconductor circuit is employed in VLSI circuits having high switching speeds

Title: Apparatus and method for measuring blood constituents
Inventor: FLOWER RONALD J
IPC: G01N21/31
Filed: 1988-10-17
Granted: 1993-08-10
Abstract: ABSTRACT OF THE DISCLOSURE         This invention  provides an apparatus and method for measuring variations in the opacity of blood due to blood volume changes related to Traube-Herring waves, respiration, heart pulsation, and hydrostatic pressure. Data relating to opacity variations is obtained by passing light of known wavelengths through blood containing tissue such as a finger or earlobe.  For the purpose of determining the saturated oxygen content of the blood, the cyclic variations due only to the heart pulsations are extracted from the measurements and are corrected for the effects of the Traube-Herring waves.  Calculation of heart rate and saturated oxygen content is performed using a programmed microprocessor.  The same microprocessor also dynamically controls the data measurement function in a manner that optimizes the measurements under a variety of changing conditions.

Title: Method to automatically vary displayed object size with variations in window size
Inventor: TORRES ROBERT J
IPC: G06F3/048
Filed: 1988-11-18
Granted: 1991-12-10
Abstract: ABSTRACT    A method to maintain all information originally displayed in a window on a display screen as the size of the window is varied.  By selecting from a plurality of different character sets that are stored in the system, a character set is obtained which has the appropriate width and height attributes that allow the original text characters to be substituted for the corresponding text characters originally displayed.          Since the selected character set contains proportionally smaller characters no information is lost when the size of the window is decreased.  The different character sets that are stored may be hardware implemented or software generated character sets which are also based on different sized character sets.  The type of font is important only in the context that some fonts are more readable as the size of the characters decrease than others.  The method allows the operator to dynamically vary the window size after the initial window has been displayed in response to some predetermined action by the operator.  The amount of decrease in window size is calculated in real time by monitoring the movement of mouse and cursor position.  A table is stored in memory which lists all of the displayable character sets that are available.          Each character set has a width attribute and a height attribute.  A percentage decrease in width and height is stored in the table representing changes from the corresponding attributes of standard character set that is normally used to display information in the system.          A new character set is selected from the table in accordance with the calculated percentage of decrease and the new character substituted in the text.  If the user decides to restore the window to its original size, a 1-step key or mouse button sequence is available.
