Abstract: Embodiments of this disclosure are directed to a wearable blood pressure measurement device having an inner sleeve and a cuff module. The inner sleeve is wearable on a limb of a user and has a first attachment mechanism. The cuff module has a second attachment mechanism that is attachable to the first attachment mechanism. The cuff module includes a cuff configured for placement over the inner sleeve, a bladder assembly having one or more bladders configured to expand and contract in response to a flow of a fluid therethrough, and a controller. The controller is configured to measure a blood pressure of the user while controlling expansion and contraction of the one or more bladders.

Abstract: A consumer electronic product includes a switchable inductor array coupled to the RF antenna, the switchable inductor array comprising inductive elements and a switch circuit coupled to the inductor array to select at least one of the inductive elements and couple the selected inductive element with the RF antenna. The product can further include an assembly having a mesh that is strengthened by a stiffener. A multi-layer adhesive have a conductive layer that can be used to shield the RF antenna and adhesive layers that can provide adhesion between the stiffener and the housing of the product. The assembly can be covered by a cowling that is made of metal to provide further shielding. To reduce potential coupling between the RF antenna and the cowling, the cowling can have a portion that is formed of plastic to distance its metal portion from the antenna.

Abstract: This disclosure describes a speaker assembly suitable for use in a portable electronic device utilizing water resistant ports. The speaker assembly can have an open back that subjects a back volume of the speaker to pressure differentials within a device housing of the portable electronic device. The speaker assembly can utilize a speaker surround having a varying thickness. The varying thickness speaker surround allows the speaker to maintain an acceptable frequency response profile while limiting the travel of the diaphragm it is coupled with. The disclosure also describes how electrically conductive pathways can be integrated within a housing of the speaker assembly.

Abstract: An electronic device having several modifications designed to prevent liquid ingress into an opening (or openings) of the electronic device is disclosed. For example, the electronic device includes a SIM tray having a sealing element designed to provide a seal at an opening that receives the SIM tray. The sealing element may include a first section and a second section extending from the first section, with the first section designed to bend with respect to (and in some cases collapse onto) the second section. The electronic device may further include an audio module fitted with a sealing element. The sealing element may include extensions extending away from a main body of the sealing element, with some extension designed to engage the audio module, and other extensions designed to engage an audio module interface. The sealing element provides a seal against liquid ingress into the audio module.

Abstract: An electronic device having openings covered by a vent assembly is disclosed. The vent assembly may include multiple adhesive layers surrounding an air-permeable, liquid resistant membrane that allow air to flow into and/or out of the electronic device, while also preventing liquid ingress into the electronic device. The membrane may be supported by several structural elements. For example, the vent assembly includes an adhesive layer secured with the membrane, with the adhesive layer including a web region having multiple ribs that engage the membrane. Also, the vent assembly includes a mesh material that includes a porous region that receives a portion of the adhesive layer. Also, an additional vent assembly may cover an additional opening of the electronic device and provide protection for an operational component in the electronic device. The additional vent assembly may allow air into the additional opening for the operational component.

Abstract: An electronic device having liquid-resistant modifications that prevent liquid ingress into an opening (or openings) in an enclosure of the electronic device is disclosed. For example, the electronic device may include a coating formed from a liquid-resistant material that is applied internally to the enclosure. The electronic device may further include a frame that carries a protective transparent layer designed to cover a display assembly. In order to secure the frame with the enclosure, the electronic device may include an adhesive assembly disposed over an outer perimeter of the coating. The adhesive assembly may include several adhesive parts initially separate from one another. However, with the adhesive parts between the frame and the enclosure, the adhesive parts can be compressed by the frame and the enclosure, causing the adhesive parts to expand and engage each other. As a result, the coating and the adhesive parts provide a seal against liquid.
