A diving computer with coupled antenna and a water contact assembly is disclosed. The diving computer has at least one radiator element located on or connected to an outermost surface of a bezel of the diving computer and a radio unit having a conductive coupling to said radiator element, for enabling wireless communication between said diving computer and external devices. A conductive water contact surface extends through the housing of the diving computer and a water contact detector circuit is arranged, as a part of an underwater condition sensing circuit, to sense an underwater condition of the device. When water establishes a current path through said underwater condition sensing circuit from the water contact surface to ground, the sensing circuit provides an indication of an underwater condition to the diving computer.

A coupled antenna apparatus particularly well adapted for small form factor, metal encased applications that utilize satellite wireless links, e.g. GPS. Certain examples use electromagnetic feeding that includes one or more separate feed elements that are not galvanically connected to a radiator element of the antenna. Additionally, one radiator element of the antenna can be located on an outermost surface of a bezel of an electronic device, for example a wrist-wearable device. A resonating circuit is housed within an electronic device and electrically coupled to such an outer radiator element.

Additionally, one radiator element of the antenna can be located on an outermost surface of a bezel of an electronic device, for example a wrist-wearable device. A low capacitance transient voltage suppressor diode is housed within an electronic device and electrically coupled to such an outer radiator element.

Coupled antenna structure and methods

The invention concerns an electronic device for personal use and a coupled antenna apparatus for such a device, comprising a top cover and a housing with an opposing back cover configured to form a closed space between said top and back cover that is adapted to receive electronic circuitry and a display unit. A bezel made of a conductive material is forming a rim on top of said housing and is interfacing with the top cover. According to the invention, an elongate strip of a conductive material deposited on a first side of an elongate antenna feed element and is forming a first radiating element and a second elongate strip of a conductive material deposited on a second side of the antenna feed element is forming a second radiating element, whereby the first and second radiating elements are positioned in proximity against the bezel at at least one inner wall portion of the bezel that extends in a direction between the first and second radiating elements and the display unit. The first and second radiating elements are functionally coupled to said bezel to form an antenna system of said electronic device.

The invention relates to a method and system in connection with a wristop computer (). In the method, the wristop computer () is used to determine at least one of the following data in a game of golf: position, time, height, distance travelled, or club used. According to the invention, the club striking the ball is determined with the aid of a measurement and at least one datum of the game of golf is recorded, in such a way that the recording is triggered from the measurement of the club () striking the ball ().

Method in connection with a wristop computer and a wristop-computer system

The invention concerns a wrist-wearable electronic device comprising a slot antenna and a method of manufacturing the slot antenna. Such a device comprises an outer housing defining an assembly zone and a radio unit contained within the assembly zone. According to the invention the outer housing is made at least partly of conductive material and comprises an integral slot antenna formed in the conductive material portion thereof, the antenna being electrically connected to the radio unit. The invention provides a convenient antenna structure for wirelessly communicating wristop computers and the like.
