A portable electronic device (biological information measurement device) is attachable to or detachable from a cradle and includes a USB terminal portion connected to a terminal provided in the cradle, an initial start-up unit that initially starts up the biological information measurement device, a connection determination unit that determines whether the connection has been released after the USB terminal portion has been connected to a terminal portion of the cradle, and a resetting unit that causes the initial start-up unit to initially start up the biological information measurement device when it is determined by the connection determination unit that the connection has been released after the cradle has been connected to the USB terminal portion.

Portable electronic device

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 unitto measure environment information around the wearing location and to transmit environment information data, and a dive computerto receive environment information data from the external sensor unitand 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.

Diver information processing apparatus and method of controlling same

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.

Data processing apparatus for divers and a data processing method, program, and recording program storing the same

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 is changed to a log mode by performing a manipulation, and to a plan and surface mode by performing another manipulation. In the plan and surface mode , 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 , plan and surface mode , and log mode is automatically changed to a dive mode . After the dive mode is designated, if a diver ascends, the dive mode is automatically changed to the plan and surface mode . Even when a diver ascends, the diver need not manipulate any external manipulation member but can plan a diving schedule immediately.

Diver's information display device

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.
