Systems and methods for providing a health coaching message are disclosed. The method may include processing an electronic audio file to generate audio pace data, storing the audio pace data, receiving the electronic audio file and pace data, collecting electronic fitness data during a fitness activity; generating activity pace data; and playing the electronic audio file based on a comparison of the audio pace data and the activity pace data.

A hearing assistance device comprises a housing component (32, 33) enclosing processing circuitry arranged in a compact block structure (20), at least one actively driven antenna element (23, 24) arranged in between the compact block structure (20) and the housing component (32, 33), and a parasitic element (25, 26) integrated in the housing component (32, 33) and extending along at least a part of the at least one actively driven antenna element (23, 24). The parasitic element (25, 26) is electrically isolated from the at least one actively driven antenna element (23, 24).

An antenna receiving apparatus includes, a first antenna; a second antenna that is synchronized with a frequency band different from the first antenna; a substrate that includes a receiving circuit connected to each of the first antenna and the second antenna; and a back lid that includes a conductor, wherein the conductor is in at least a portion of the back lid. The substrate includes a grounding surface of the first antenna. The substrate and the second antenna are positioned between the first antenna and the back lid. The second antenna is positioned on a side of the substrate opposite of the first antenna, and the second antenna is electrically connected to the conductor of the back lid and grounded.

A wearable device includes a frame and a magnetic coupler opening formed in the frame. Wearable device further includes a processor, a memory accessible to the processor, and a very high frequency (VHF) radio transceiver for data transmission and reception and connected to the processor. Wearable device further includes a magnetic coupler connected to the VHF radio transceiver. Magnetic coupler includes a diamagnetic material shaped to form a VHF transmission or reception terminal that partially or fully aligns with the magnetic coupler opening. During transmission, magnetic coupler is configured to radiate transmitted VHF band radio modulated signals into tissue of the user. During reception, magnetic coupler is configured to absorb received VHF band radio modulated signals from the tissue of the user.

A wearable device includes a metal frame, a printed circuit board PCB, and a first feeding element, where a slot is formed between the metal frame and the PCB.

The first feed point is disposed in the first area, and a distance between the first feed point and the first ground point along the metal frame is less than one third of the circumferential length corresponding to the first area.

The present disclosure relates to a hearing device comprising a first radar sensor configured for obtaining first radar data indicative of a difference in the orientation of a head of the user and a further body part of the user. A processing unit of the hearing device is configured to receive the first radar data from the first radar sensor and determine, based on the first radar data, a first relative orientation, wherein the first relative orientation is a difference in the orientation of the head of the user and the further body part of the user.

A wire-patch antenna includes a ground plane; a capacitive roof placed facing the ground plane at a predetermined distance of separation; a probe feed; at least one electrically conductive short-circuiting wire linking the capacitive roof and the ground plane, the short-circuiting wire being intended to excite a first resonant mode at a first resonant wavelength; and at least one electrically conductive impedance-matching wire linking the conductive short-circuiting wire and the probe feed so as to create a parasitic inductor.

Techniques described herein may be used to implement a 4G antenna in a wearable device (e.g., a watch) in a manner that optimizes the ability of the antenna to send and receive radio signals while minimizing the user's exposure to radio signals. The antenna may be raised above a base portion and a printed circuit board (PCB) of the wearable device to limit radio signals being absorbed by the user's body, in addition to providing a vertical space between conductive components (such as the PCB), metal nodes to which the PCB is attached, etc.) that might otherwise interfere with radio signals to and from the antenna. The antenna may also be split into two different portions (a first portion and a second portion) in order to limit radio signals from resonating in the antenna for longer than is beneficial.

Embodiments relate to a wearable communications node (WCN) with mesh networking capabilities. The WCN, which is worn on the user's torso, includes an enclosure and shoulder strap(s) as well as communications device, antenna element(s), and battery conductively coupled to a control circuit. The enclosure includes a top area and an oppositely positioned bottom area. The shoulder strap is pivotably attached proximate to the top area and the bottom area. The communications device is rigidly affixed within the enclosure. The antenna element is conductively coupled to the communications device as well as rigidly affixed to the enclosure or flexibly affixed the shoulder strap. The control circuit is configured to establish, via the communications device, a self-organizing wide area network with a plurality of computing devices that each connects directly, dynamically, and non-hierarchically to the WAN. The antenna element includes a conductive composition that includes graphene dispersed in a polymer matrix.
