Abstract: Devices, systems, and methods facilitate enrollment of authenticating biometric data for authenticating an authorized user via a biometric sensor. Included devices transmit power to a sensor-enabled device that does not have an independent power source without transmitting data to or from the device. Data input devices coupled to the biometric sensor enable user input of non-biometric data, such as an activation code, via the biometric sensor. For biometric sensors comprising fingerprint sensors, finger guides position a finger to contact the sensor at a desired orientation. Systems and methods allow for enrollment of one or more authenticating biometric data templates with or without requiring input of non-biometric authentication data, such as an activation code.

Abstract: A sensor has parallel upper pickup lines in an upper conductive layer, parallel lower pickup lines in a lower conductive layer, parallel drive lines oriented transversely to the upper and lower pickup lines in a middle conductive layer, a first insulating layer separating the upper pickup lines from the drive lines, and a second insulating layer opposite the first insulating layer and separating the lower pickup lines from the drive lines. Upper electrode pairs are defined at locations where an upper pickup electrode crosses a drive line, and each upper electrode pair has an impedance that is sensitive to a first object contacting or in close proximity to the upper electrode pair. Lower electrode pairs are defined at locations where a lower pickup line crosses a drive line, and each lower electrode pair has an impedance that is sensitive to a second object contacting or in close proximity to the lower electrode pair.

Abstract: A sensor assembly comprises a rigid substrate with a circuit subassembly wrapped therearound. The circuit subassembly includes a flexible substrate with conductive traces and interconnects formed thereon, and when wrapped around the rigid substrate, the conductive traces may overlap one another so as to form capacitive sensor elements. The interconnects connect the conductive traces to one or more components, such as a printed circuit board attached to a portion of the flexible substrate. The sensor assembly maybe installed in an opening formed in a host device panel of a host device, such as a smart phone, with the sensor assembly optionally peripherally surrounded by a spacer frame, and covered by a cover element. The circuit subassembly may include a host connector tab for electrically connecting the sensor assembly to electrical components of a host device.

Abstract: A method of securing a fingerprint sensor into a host device panel comprises, in one embodiment, securing a cover panel to the fingerprint sensor assembly and then securing the covered fingerprint sensor into a hole formed in the host device panel. In another embodiment, the cover panel is secured within a hole formed in the host device panel, and then the host device panel is placed over the fingerprint sensor assembly with the cover member aligned with the sensor assembly.

Abstract: A sensor has drive lines and transverse pickup lines to define an electrode pair where each pickup line crosses a drive line. A reference pickup line is arranged parallel to the pickup lines and a compensation drive line is arranged parallel to the drive lines. A signal source provides a first signal to the drive lines and a second signal that is the inverse of the first signal to the compensation drive line. An amplifier has a first input connected to a pickup line, a second input connected to a reference pickup line, and a output indicative of an object in contact with the electrode pair(s). Each impedance between the compensation drive line and a pickup line, between the reference pickup line and a reference drive line, and between the compensation drive line and the reference pickup line is equal to the impedance at the electrode pair when no object is contact with the electrode pair.
