Assignee:

APPLE INC. - Cupertino CA

International Classification:

G06F 3/044

US Classification:

345174

Abstract:

An apparatus comprises a fingerprint sensor having a set of capacitive elements configured for capacitively coupling to a user fingerprint. The fingerprint sensor may be disposed under a control button or display element of an electronic device, for example one or more of a control button and a display component. A responsive element is responsive to proximity of the user fingerprint, for example one or both of a first circuit responsive to motion of the control button, and a second circuit responsive to a coupling between the fingerprint and a surface of the display element. The fingerprint sensor is disposed closer to the fingerprint than the responsive element. The control button or display component may include an anisotropic dielectric material, for example sapphire.

International Classification:

G11B 700

US Classification:

369 59, 369 592

Abstract:

The invention provides a method and apparatus for generating delays to shift edges of an EFM data stream from an EFM modulator for a CD-R and CD-RW write encoder. EFM data pulse edges may be delayed in increments of about {fraction (1/32)} Tefm where Tefm is the code rate clock of an EFM data stream output. The delays are generated by a synthesizer running at four times the EFM code rate. The synthesizer may be built using a four-stage ring oscillator. Delays are selectable based upon the write strategy matrix in coarse increments of  T and fine increments of {fraction (1/32)} T. For the coarse delay, the EFM data may be passed through a four stage shift register running at Fsynth, where Tefm=4ÃFsynth, allowing for a coarse delay selection of  Tefm. The four stages of the ring oscillator provides eight phases of the synthesizer, each phase shifted by â Tsynth thereby providing a delay selection of â within each Tsynth period, translating into {fraction (1/32)} Tefm resolution. The method and apparatus of the present invention may be extended to even finer delays by increasing the number of stages in the ring oscillator.

International Classification:

G06K 9/00
G06F 3/044

Abstract:

An apparatus comprises a fingerprint sensor having a set of capacitive elements configured for capacitively coupling to a user fingerprint. The fingerprint sensor may be disposed under a control button or display element of an electronic device, for example one or more of a control button and a display component. A responsive element is responsive to proximity of the user fingerprint, for example one or both of a first circuit responsive to motion of the control button, and a second circuit responsive to a coupling between the fingerprint and a surface of the display element. The fingerprint sensor is disposed closer to the fingerprint than the responsive element. The control button or display component may include an anisotropic dielectric material, for example sapphire.
