Abstract
A carrier for a sweep-type fingerprint sensor and a method of operation are disclosed. The carrier has a recess for receiving and mounting the fingerprint sensor and one or more tactile elements for assisting the user in positioning a finger, and in correctly moving the finger across the sensor being read. In one embodiment the tactile element consists of an oval ridge, or a portion thereof, defining a major axis which is lies in the sweep direction. The tip of the finger is initially positioned in the arcuate portion of the oval ridge and is moved across the sensor, generally along the axis of the oval. The side walls of the ridge assist the user in correctly moving the finger across the sensor.
Claims17
A self-aligning carrier for a sweep-type fingerprint sensor comprising:
- a body having an upper surface and comprising an recess in said upper surface for receiving a generally rectangular sweep-type fingerprint sensor having long sides and a short sides,
- a least one tactile element positioned on said upper surface adjacent to each said short side for assisting a user is moving a finger across said sensor in a desired path.
A self aligning carrier for a sweep-type fingerprint sensor comprising:
- a body having an upper surface and comprising an recess in said upper surface for receiving a generally rectangular sweep-type fingerprint sensor having long sides and a short sides,
- at least one tactile element positioned on said upper surface of said body, for assisting a user in correctly positioning a finger to be sensed, and in correctly moving the finger across the surface of said sensor.
A structure for positioning a finger on a sweep-type fingerprint sensor having an axis defining the direction of finger movement across the sensor, comprising:
- an arcuate tactile member comprising one or more tactile elements positioned on the axis of the fingerprint sensor, and
- at least one tactile member adjacent to each side of the fingerprint sensor.
A method of sensing a fingerprint using a sweep-type fingerprint sensor, comprising:
- positioning the tip of a finger using an arcuate ridge located adjacent to a fingerprint sensor,
- thereafter, moving the finger across the sensor.
