Patent number: 5994143Abstract: Fluorescent conjugates suitable for use in flow cytometry and other biological applications. The fluorescent conjugates comprise an antibody having a polymeric dye bound thereto. The polymeric dye is preferably enhanced by a hydrophobic and conformationally restrictive moiety either bound thereto or in close association therewith. The hydrophobic and conformationally restrictive moiety is preferably derived from a cyclodextrin. The polymeric dye comprises a polymeric entity having signal-generating groups, such as aminostyryl pyridinium dye residues attached thereto. The fluorescent conjugates exhibit exceptional stability characteristics and avoid many of the problems of energy transfer, bio-conjugability, and solubility.Type: GrantFiled: February 1, 1996Date of Patent: November 30, 1999Assignee: Abbott LaboratoriesInventors: Christopher Bieniarz, Jeffrey B.

Patent number: 5955618Abstract: A field identification signal generating circuit for a receiver for receiving a high-definition signal, and a method therefor. According to the method, a first correlation value is calculated, between the high-definition signal and a first reference signal the same as a first known signal. A timing control signal, synchronized with a second known signal whose phase is alternately inverted in every field, is output when the first correlation value is greater than or equal to a predetermined value. A second correlation value is calculated, between the high-definition signal and a second reference signal the same as the second known signal. Information on the polarity of the second correlation value is output. A field identification signal is generated on the basis of the polarity information on the second correlation value which is synchronized with the timing control signal. Therefore, the field identification signal generating circuit can be realized with simple hardware.Type: GrantFiled: January 20, 1998Date of Patent: September 21, 1999Assignee: Samsung Electronics Co., Ltd.Inventor: Ki-bum Kim
