Patent number: 7606440Abstract: In a linear image sensing device with image matching function, a linear sensors array senses a finger, which is moving over it, to obtain fragment image analog signals, which are amplified, by a programmable gain amplifier, into amplified signals. An analog-to-digital converter sequentially converts the amplified signals into digital image signals. An image matching module sequentially receives and processes adjacent two of the digital image signals, and outputs continuous non-overlapped fragment images through an input/output interface. A control logic controls operations and communications of the above-mentioned components. A terminal system receives the non-overlapped fragment images and assembles the non-overlapped fragment images into a complete fingerprint image in a manner of stacking the images side by side.Type: GrantFiled: March 16, 2006Date of Patent: October 20, 2009Assignee: Egis Technology Inc.Inventors: Bruce C.

Patent number: 7519829Abstract: A storage device to be connected to a terminal host includes a control module to be connected to the host, and a biometrics sensor and a storage unit both connected to the control module. The host runs a biometrics application program (AP) to inform the control module to control the sensor to read to-be-identified biometrics data of a user and to determine whether the to-be-identified biometrics data matches with biometrics template data stored in the storage device. When the two sets of data match with each other, the host runs a host-specific-code generating program to generate and transfer a host specific code to the control module. The control module generates a device specific code using a device-specific-code generating program stored therein, determines whether the codes match with each other, and enables the host to access a data protection unit of the storage device when the codes match with each other.Type: GrantFiled: June 15, 2006Date of Patent: April 14, 2009Assignee: EGIS Technology Inc.Inventors: Bruce C.
