The invention relates to a wearable diving computer coupled with an antenna and a water contact assembly and / or a water contact detector assembly for detecting underwater conditions of a wearable device. The computer includes: a shell including a conductive loop of a radiator element and a body; a radio unit functionally connected with the diving computer circuit in the housing, having a conductive coupling to the radiator element, allowing the diving computer to wirelessly communicate with an external device; at least a partially electrically conductive water contact surface extending throughthe body; a water contact detector circuit which can sense the underwater condition of the submersible computer; an underwater condition sensing circuit including a water contact surface, a radiatorelement, and a low-pass filter, including an inductor having one end connected to the conductive coupling portion and the other end connected to a ground potential of the submersible computer. The water contact detector circuit detects an electrical connection from the water contact surface to ground when water establishes a current path through the underwater condition sensing circuit and provides an indication of the underwater condition to the submersible computer.
Description
technical field [0001] The present invention relates generally to electronic devices, such as wireless or portable radios, and to methods of use thereof. In particular, the present invention relates to dive computers and water contact detection assemblies for such dive computers. Background technique [0002] Antennas are commonly provided in most modern radio devices such as mobile computers, portable navigation devices, mobile phones, smartphones, personal digital assistants (PDAs) or other personal communication devices (PCDs). Typically, these antennas include a planar radiating element and have a ground plane generally parallel to the planar radiating element. The planar radiating element and the ground plane are usually connected to each other via short-circuit conductors in order to achieve the desired impedance matching of the antenna. The structure is configured such that it acts as a resonator at the desired operating frequency. Typically, these internal antenna...
