Title: Amplifier Output Stage Having Enhanced Drive Capability
Inventor: EMBREE MILTON LUTHER
IPC: H03F3/30
Filed: 1996-11-27
Abstract: The invention is an operational amplifier having an output stage for enhancing the output driver capability near the negative source voltage. The output stage of the invention includes a voltage detector in combination with a current redirector or redirecting arrangement. The voltage detector converts the voltage difference between the amplifier output and the input to the output stage of the amplifier to a control current, which is redirected at the positive source voltage and applied to the negative output driver. The current redirector, which is operably connected to the voltage detector, allows the amplifier output to be driven at full rated current (e.g., approximately 40 mA) close to the negative source voltage (e.g., within approximately 1.5 volts) while maintaining an output configuration appropriate for stability.
Patent CA-2192340-A1 (CA)
Inventor: DUEHOLM STEN
IPC: G01N23/16
Filed: 1995-06-15
Abstract: A    method of non-destructively, on-line determining the density profile in a plate-shaped material with a density which varies discretely or continuously over the plate thickness, while the density at a specific depth of the plate is assumed to be constant, such as for instance plates based on wood, by means of X-rays or gamma rays from a source placed on one side of the plate. Two detectors are placed on the other side of the plate, one detector measuring in the emitting direction of the source and the other detector measuring in the other direction and being movable relative to the plate. The counting number of the second detector is adjusted by means of the counting number of the first detector. By a suitable choice of emitting direction and detecting direction it is possible to provide a measurement of the density in a specific measuring volume merely by dividing the counting number of the second detector by the counting number of the first detector. As a result, the attenuation in the material is left out. The angle of incidence must be substantially identical with the angle of reflection.

Patent CA-2225881-A1 (CA)
Inventor: BELL DAVID N
IPC: C07K1/107
Filed: 1997-12-29
Abstract: The present inventions describes a method to cross-link human hemoglobin obtained from umbilical cord red blood cells.  Cross-linked cord blood hemoglobin is a mixture of adult and fetal hemoglobins but it has the same molecular weight distribution and oxygen delivery capability as does cross-linked purified adult hemoglobin.  For example, unpurified cord blood hemoglobin cross-linked by O-raffinose has the same P50, Hill Coefficient, oxygen saturation and molecular weight distribution as cross-linked highly purified adult hemoglobin.  Cross-linked cord blood hemoglobin may therefore substitute for cross-linked adult hemoglobin in any use as an hemoglobin-based oxygen carrier.  This method does not require the prior separation of fetal and adult hemoglobins from cord blood before cross-linking.  Other methods of cross-linking, polymerizing or otherwise stabilizing cell-free purified or unpurified cord blood hemoglobins may serve equally well as HBOCs.  Cross-linked cord blood hemoglobin may have additional uses as an HBOC that depend upon some of the unique structural and functional characteristics of fetal hemoglobin.  Discarded umbilical cord blood provides a large source of hemoglobin for use as an HBOC.
