摘要:
Unnecessary operations are eliminated in the calculation of a non-decompression limit at the current water dept. In this manner, the calculation of the non-decompression limit is made more efficient and the required computing time is shorten to the point where the function can be incorporated into a wrist worn device that provides timely data.

A depth measuring device suitable for use in a dive watch is provided. A water depth measuring device comprising a pressure sensor, an A/D converter that converts the sensed signal of the pressure sensor into a digital value, the digital value corresponding to the start of water depth measuring being the initial digital value, a comparator that compares the initial digital value output by the A/D converter with a range of values defined by a first predetermined comparative value and a second predetermined comparative value, and determines whether the initial digital value falls within the range and produces a comparison result based thereon, an initial value setting circuit that, in response to the comparison result of the comparator, adopts the first digital value as an initial value corresponding to a zero meter depth when the initial digital value falls within the range defined by the first and second comparative values, and a water depth computer that computes a water depth value based on the initial value and the digital value derived from the A/D converter.

To provide safety-ensuring information that is considered to enhance safety in accordance with the movement of the diver's body in the water. An information processing device is provided that is worn on the diver, and has an external sensor unit 5 to measure environment information around the wearing location and to transmit environment information data, and a dive computer 4 to receive environment information data from the external sensor unit 5 and to generate and to output safety-ensuring information to ensure the safety of the diver on the basis of the environment information corresponding to the environment information data.

摘要:
In a divers' information display device, a plurality of display modes or the manner of switching features has been improved in order to thus improve the display ability of the device. The divers' information display device has simplified switching of indications and is user-friendly. Specifically, a time mode 201 is changed to a log mode 203 by performing a manipulation, and to a plan and surface mode 202 by performing another manipulation. In the plan and surface mode 202, an amount of intracorporeal nitrogen, a nitrogen discharge completion time, a depth-of-water rank, and a non-decompression diving enabled time are indicated. After plunging into water is acknowledged, any of the time mode 201, plan and surface mode 202, and log mode 203 is automatically changed to a dive mode 204. After the dive mode 204 is designated, if a diver ascends, the dive mode is automatically changed to the plan and surface mode 202. Even when a diver ascends, the diver need not manipulate any external manipulation member but can plan a diving schedule immediately.
