Abstract: Methods, systems, and devices for manufacturing a wearable device are described. A method for manufacturing a wearable device may include coupling a printed circuit board (PCB) to an inner ring-shaped housing that contains a plurality of apertures by aligning a plurality of sensors of the PCB with the plurality of apertures. The method may also include coupling an outer ring-shaped housing to the inner ring-shaped housing by surrounding the inner ring-shaped housing with the outer ring-shaped housing. Additionally, the method may include injecting a filler material through an additional aperture of the outer ring-shaped housing to fill a cavity defined by the inner ring-shaped housing and the outer ring-shaped housing, filling at least a portion of the plurality of the inner ring-shaped housing with the filler material.

Abstract: Systems and devices for optimized structures for optical measurement are described. A wearable device may include a housing configured to house one or more sensors to acquire physiological data from a user. The wearable device may further include one or more light sources disposed on a surface of the housing and positioned to direct light into a tissue surface of the user and one or more detectors disposed on the surface of the housing and positioned to receive light from the one or more light sources along a plurality of optical paths where a first optical path may be through the tissue surface and a second optical path may be directly from the one or more light sources. The wearable device may include one or more light blocking components disposed on a surface of the housing that are configured to block stray light along the second optical path.

Abstract: The present invention provides target devices such as filter units with at least one receiving channel with a stop surface that is electrically conductive and at least one cable with a connector assembly on a first end portion. The connector assembly includes a first member with an open channel. The first member is coupled to the end portion of the outer conductor with the free end of the inner conductor and the end portion of the dielectric extending through the open channel to reside forward of the first member. The first member resides in a respective one of the at least one receiving channel against the stop surface. The connector assembly also includes second member with an open channel The second member is slidably coupled to the first end portion of the at least one cable and presses the first member against the stop surface.

Abstract: A method and computer system for integrating an antenna radiator during the manufacturing of an electronic device comprising providing a first chassis component, providing the radiator into the first chassis and providing a second chassis component over the radiator so as to integrate it between the first and the second chassis components (e.g., using a two-shot molding technique). A chassis may be defined by at least the first and the second chassis elements. A mobile device having networking capabilities comprising an antenna comprising a radiator and a hardware module for providing a function other than the networking capabilities to the mobile device. The radiator is at least partially integrated with the hardware module. The hardware module may further integrate a connector. The hardware module may be a structural chassis of the mobile device and the chassis may further integrate additional components.
