This document discloses a portable system comprising a physical activity monitoring device comprising: a wireless proximity detection module configured to detect a proximity of an input control entity with respect to the physical activity monitoring device and output a control signal as a response to the detection, wherein the proximity is a non-zero distance between the input control entity and the training computer; and a user interface controller configured to generate, as a response to the control signal from the wireless proximity detection module, at least one of an audio control function and a display control function.

User interface control in portable system

A method for operating cellular connectivity in a wearable device includes configuring a sensor device to measure physical activity of a user and to output measurement data representing the measured physical activity; establishing, by using a cellular radio device included in the wearable device, cellular connectivity with an access node of a cellular communication system; and adjusting utilization of cellular uplink resources allocated to the cellular radio device according to a rate at which the measurement data from the sensor device becomes available for uplink transmission in the wearable device.

System for providing wrist device with cellular communication capability

A sensor attachable to a body of a user includes a heartbeat sensor or a motion sensor; and an antenna including a resonator structure configured to interact with a radio frequency signal. The resonator structure includes a dielectric resonator element. The dielectric resonator element is configured to resonate as a response to the radio frequency signal for at least one of transmitting and receiving electromagnetic energy wirelessly.

Sensor

A resonator structure of an electric apparatus, wherein the resonator structure is configured to interact with a radio frequency signal. The resonator structure includes a dielectric resonator element configured to resonate as a response to the radio frequency signal for transmitting and/or receiving electromagnetic energy wirelessly, and a conductive grounding structure magnetically coupled with the dielectric resonator element and configured to resonate with the dielectric resonator element. The conductive grounding structure includes at least a portion of the casing of the electric apparatus.

Resonator structure in small-sized radio devices

An antenna component (and antenna) with a dielectric substrate and a plurality of radiating antenna elements on the surface of the substrate. In one embodiment, the plurality comprises two (2) elements, each of them covering one of the opposite heads and part of the upper surface of the device. The upper surface between the elements comprises a slot. The lower edge of one of the antenna elements is galvanically coupled to the antenna feed conductor on a circuit board, and at another point to the ground plane, while the lower edge of the opposite antenna element, or the parasitic element, is galvanically coupled only to the ground plane. The parasitic element obtains its feed through the electromagnetic coupling over the slot, and both elements resonate at the operating frequency. Omni-directionality is also achieved. Losses associated with the substrate are low due to the simple field image in the substrate.

Antenna, component and methods

An antenna component () with a dielectric substrate and two radiating antenna elements. The elements are located on the upper surface of the substrate and there is a narrow slot () between them. The antenna feed conductor () is connected to the first antenna element (), which is connected also to the ground by a short-circuit conductor (). The second antenna element () is parasitic; it is galvanically connected only to the ground. The component is preferably manufactured by a semiconductor technique by growing a metal layer e.g. on a quartz substrate and removing a part of it so that the antenna elements remain. In this case the component further comprises supporting material () of the substrate chip. The antenna component is very small-sized because of the high dielectricity of the substrate to be used and mostly because the slot between the antenna elements is narrow. The efficiency of an antenna made by the component is high.

Antenna component and methods

A chip component with dielectric substrate and plurality of radiating antenna elements on the surface thereof. In one embodiment, two (2) substantially symmetric elements are used, each covering an opposite head and upper surface portion of the device. The surface between the elements comprises a slot. The chip is mounted on a circuit board (e.g., PCB) whose conductor pattern is part of the antenna. No ground plane is used under the chip or its sides to a certain distance. One of the antenna elements is coupled to the feed conductor on the PCB and to the ground plane, while the parasitic element is coupled only to the ground plane. The parasitic element is fed through coupling over the slot, and both elements resonate at the operating frequency. The antenna can be tuned and matched without discrete components, is substantially omni-directional, and has low substrate losses due to simple field image.
