Patent number: 11415405Abstract: Disclosed herein is a strain gauge including a substrate, with a first Wheatstone bridge arrangement of resistors disposed on a first surface of the substrate, and a second Wheatstone bridge arrangement of resistors disposed remotely from the first Wheatstone bridge arrangement of resistors. The resistors of the first Wheatstone bridge arrangement are equal in resistance to one another, while the resistors of the second Wheatstone bridge arrangement are unequal in resistance to one another and unequal to those of the first Wheatstone bridge arrangement. The first Wheatstone bridge arrangement of resistors are electrically connected in parallel with the second Wheatstone bridge arrangement of resistors such that each resistor of the first Wheatstone bridge arrangement is electrically connected in parallel with a different resistor of the second Wheatstone bridge arrangement.Type: GrantFiled: April 24, 2020Date of Patent: August 16, 2022Assignee: STMicroelectronics Asia Pacific Ptd LtdInventors: Sa Hyang Hong, Jun Hwan Kang, Yun Sang On

Patent number: 11353373Abstract: A strain gauge includes first and second substrates spaced apart from one another. A first flexible printed circuit board portion is in contact with a top side of the first and second substrates, and has a first Wheatstone bridge formed therein. The first flexible printed circuit board portion positions the first Wheatstone bridge such that two resistors of the first Wheatstone bridge are positioned to span from the top side of the first substrate to the top side of the second substrate. A second flexible printed circuit board portion is in contact with a bottom side of the first and second substrates, and has a second Wheatstone bridge formed therein. The second flexible printed circuit board positions the second Wheatstone bridge such that two resistors of the second Wheatstone bridge are positioned to span from the bottom side of the first substrate to the bottom side of the second substrate.Type: GrantFiled: May 29, 2020Date of Patent: June 7, 2022Assignee: STMicroelectronics Asia Pacific Pte LtdInventors: Min Sang Kim, Chan Hyuck Yun, Sa Hyang Hong, Ju Hyun Son

Patent number: 7403271Abstract: An optical fingerprint image input device for a mobile apparatus includes: a plate-shaped fingerprint contact member; a distortion correcting member for correcting distortions; light sources disposed at both sides of the fingerprint contact member, other than an inclined surface or a back light source in a liquid crystal display element; focusing means disposed at an inclined surface side of the distortion correcting member; and an image sensor. In other words, the fingerprint contact member and the distortion correcting member having respective set-up inclined angles are disposed to discern sweat, water or oil and to correct a trapezoidal distortion which is a disadvantage that occurs when a thin fingerprint contact medium is used, and to form a lens system comprised of a cylindrical lens and a spherical lens for adjustment of a ratio of transversal to longitudinal widths of an image.Type: GrantFiled: September 14, 2004Date of Patent: July 22, 2008Assignee: Secutronix Inc.Inventors: Hyun Kim, Young Jin Seo, Jong Woo Ahn, Seung Min Lee, Sa Hyang Hong, Tae Hun Lee, Byung Kee Kwak
