Abstract: Improving the accuracy of ultrasonic touch sensing and fingerprint imaging using acoustic impedance matching is disclosed. Acoustic impedance mismatches between an ultrasonic transducer array and a sensing plate can be reduced to maximize energy transfer and minimize parasitic reflections. A reduction in acoustic impedance mismatches can be accomplished using (i) a composite epoxy having a higher acoustic impedance than epoxy alone, (ii) one or more matching layers having an acoustic impedance that is approximately the geometric mean of the acoustic impedance of the sensing plate and the acoustic impedance of the transducer array, (iii) pores or perforations in the sensing plate, or (iv) geometric structures formed in the sensing plate. In addition, parasitic reflections can be suppressed using an absorbent layer.

Abstract: An electronic device includes a housing sidewall defining an opening and a display component, such as a display cover, disposed in the opening to form a gap between the housing sidewall and the display component. In at least one example, the cavity is defined by the sidewall and the display cover with the cavity in fluid communication with an external environment through the gap. In at least one example, an epoxy component at least partially defines the cavity and can be in direct contact with the housing sidewall.

Abstract: A modular sensing assembly may be used to detect user inputs at an electronic device. Example user inputs include touch inputs, fingerprint inputs, translational inputs, audio inputs, biometric inputs, and the like. Inputs received using the modular sensing assembly may be used to control a graphical output of a display of the electronic device. A modular sensing assembly may be configured, for example, as a power button, a key of a keyboard, a control button (e.g., volume control), a home button, a watch crown, and so on.

Abstract: A wearable electronic device may include a display and a housing. The housing may include a chassis defining a first portion of a rear exterior surface of the wearable electronic device, a first portion of a side exterior surface of the wearable electronic device, and an internal wall. The housing may also include a glass shell defining a front wall positioned over the display and defining a front exterior surface of the wearable electronic device and a side wall extending from the front wall and overlapping the internal wall, the side wall defining a second portion of the side exterior surface of the wearable electronic device. The wearable electronic device may also include a touch sensing system within the housing and configured to detect a touch input applied to the front exterior surface of the wearable electronic device.

Abstract: A first device such as a wristwatch may include a front face at which a display is disposed and a rear face at which a rear housing wall is mounted. Antenna structures may overlap the rear housing wall and may be operable to transit and receive relatively high frequency signals through the rear housing wall to a communication with a second device such as a wireless power transmitting device for the wristwatch. The second device may also include antenna structures that overlap a top surface housing. Respective sets of magnetic structures may be provided in the first and second devices to align the two devices and to form a reliable wireless communication link between the two devices. The first and second devices may include respective antenna arrays that include pairs of antenna elements that are selectively used to form a reliable wireless communication link.

Abstract: Embodiments are directed to a portable electronic device having a substantially concealed barometric vent. The vent may be used to equalize air pressure within the enclosure while forming a barrier between external contaminants, moisture, and so on and various internal component and assemblies of the device. In one embodiment, the vent may include a screen configured to impede ingress of particulates and an air-permeable membrane configured to impede ingress of moisture.
