When the Brownian motion of beads is restricted, the presence of the known nucleic acid sequence is in the sample, thus indicating that the targeted nucleic acid sequence is the known nucleic acid sequence.Type: GrantFiled: May 29, 2015Date of Patent: August 1, 2017Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Venkat K.

Patent number: 9632033Abstract: A technique relates to determining a presence of a known nucleic acid sequence of a known molecule in a sample. A sample surface is coated with a select segment of the known molecule. Beads are coated with a first molecule. A targeted nucleic acid sequence is attached to a second molecule that binds to the first molecule, such that the targeted nucleic acid sequence is attached to the beads via first and second molecules. The sample is placed on the sample surface. The sample includes the liquid medium, beads, and targeted nucleic acid sequence being tested. Brownian motion of beads is monitored to determine whether the Brownian motion of the beads is restricted or not restricted. When the Brownian motion of beads is restricted, the presence of the known nucleic acid sequence is in the sample, thus indicating that the targeted nucleic acid sequence is the known nucleic acid sequence.Type: GrantFiled: June 22, 2015Date of Patent: April 25, 2017Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Venkat K.

Patent number: 9544558Abstract: Provided is a phase shift amount measuring apparatus and method capable of measuring a phase shift amount and a transmittance of a phase shift mask in one measurement step by using a miniaturized monitor pattern. The phase shift amount and transmittance of the monitor pattern are simultaneously measured using a shearing interferometer. The phase shift amount is obtained from a phase difference of interference light between light passing through the monitor pattern and light passing through a non-pattern area. The transmittance of the monitor pattern is obtained using an amplitude of interference light between light passing through the monitor pattern and light passing through the non-pattern area and an amplitude of interference light between light beams passing through the non-pattern area. The use of common interference images in measuring the phase shift amount and transmittance enables measurement of both the phase shift amount and the transmittance in one measurement operation.Type: GrantFiled: December 2, 2014Date of Patent: January 10, 2017Assignee: Lasertec CorporationInventors: Koyo Tada, Hiroto Nozawa, Hideo Takizawa
