Filed:

Sep 15, 2022

Appl. No.:

17/945442

Inventors:

- Cupertino CA, US
James T Curran - Cupertino CA, US
Joseph Hakim - Soquel CA, US

International Classification:

A61B 5/05
A61B 5/0205

Abstract:

Systems and methods for determining fine grain motions and vibrations of live and/or inanimate objects are described based on using a radar system. For example, biometric information may be extracted from such vibrations associated with a live object. In different embodiments, processing circuitry may perform different statistical analysis on reflections from the objects. Moreover, the processing circuitry may perform different processing functions based on the statistical analysis to determine the vibrations with high accuracy. Furthermore, the processing circuitry may also select one or multiple target maps based on a field of view of the radar system for a more robust measurement of the vibrations associated with one or multiple objects.

International Classification:

C25D 11/26

Abstract:

An enclosure for a portable electronic device can include a titanium substrate defining a textured surface and a nominal surface. The titanium substrate can include a first region that extends above the nominal surface and a second region adjacent to the first region and extending below the nominal surface. A separation distance between an apex of the first region and a bottom of a trough defined by the second region can be at least 1 micrometer. A metal oxide layer can overlay the trough defined by the second region.

Abstract:

A method of forming a surface coating on a component of an electronic device can include depositing an aluminum layer including at least about 0.05 weight percent (wt %) of a grain refiner on a surface of the component by a physical vapor deposition process, and anodizing the aluminum layer to form an anodized aluminum oxide layer having a L* value greater than about 85 in the CIELAB color space.

Abstract:

Anodizing techniques for providing highly opaque colorized anodic films are described. According to some embodiments, the methods involve depositing a pigment having a particle diameter of about 20 nanometers or greater into an anodic film. Additionally or alternatively, a barrier layer smoothing operation is used to flatten an interface between the anodic film and underlying metal substrate so as to maximize light reflection off the interface, thereby maximizing light reflected off the pigment that is deposited within pores of the anodic film. The resulting anodic films have an opaque or saturated colored appearance. In some embodiments, the methods involve increasing a thickness of a non-porous barrier layer of the anodic film so as to create thin film interference effects that can add a particular hue to the anodic film. The methods can be used form cosmetically appealing coatings for consumer products, such as housings for electronic products.

International Classification:

G01N 19/04

Abstract:

This disclosure relates to rapid and repeatable tests that can be used to evaluate the interfacial adhesion of coatings to substrates. In particular embodiments, tests are used to assess the resistance of anodic oxides to delamination from aluminum substrates. The tests can be conducted using standard hardness test equipment such as a Vickers indenter, and yield more controlled, repeatable results than a large sample of life-cycle tests such as rock tumble tests. In particular embodiments, the tests involve forming an array of multiple indentations within the substrate such that stressed regions where the coating will likely delaminate are formed and evaluated.
