Abstract
Device for scuba diving consisting of at least a processor and of at least a manometer, both housed within a sheath, said manometer being connected to one or more bottles containing compressed air. The said processor includes a corresponding central unit for data processing, operatively connected to the manometer by means of connecting elements which allow said processor and said manometer to exchange information flows and also to be positioned within the housing sheath independently one from the other, so as to obtain a device for scuba diving with a modular structure.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to information providing devices used by scuba divers during diving sessions.
2. Background of the Invention
As is known, during a diving session with bottles the diver needs to know and check a given amount of data, among which the remaining pressure of the bottles, the remaining air time, the air consumption, the length of the decompression stages and others. To this purpose it is known to provide integrated computers for scuba diving carrying out, by means of suitable sensors, a series of checks on the parameters which are necessary for the calculation and the visualization on a suitable display of said data; for instance said integrated computers are connected by means of a pipe or intake to a pressure sensor placed on the first stage of pressure reduction at the output of the bottles. Said known computers, therefore, combine the functions of a processor provided with a central processing unit or CPU (Control Process Unit) with those of a traditional manometer integrated with said processing unit, at least partially separating the circuits. Said integration between the processing unit and the manometer involves some obvious constructing problems and turns the computer for scuba diving into a highly sophisticated device, extremely expensive to buy and maintain, since the diver has to buy both the processing unit and the manometer, said unit and said manometer being integrated and not to be separated, and moreover, in case the unit or the manometer get damaged, both have to be replaced.
SUMMARY OF THE INVENTION
The present invention, therefore, aims at providing a device for scuba diving which, beyond being versatile and easy to build, allows the scuba diver to buy its constituting elements separately, that is to say either the processor or the manometer, and to mount them onto a single support even at different times, and which also enables, if either element gets damaged, the replacement of said element independently from the other element and from the rest of the computer.
Said aim is achieved by the present invention by means of a device for scuba diving consisting of at least a processing unit and of at least a manometer, both being housed within a sheath, said manometer being connected to one or more bottles containing air under pressure; in said device the processor consists of a corresponding central unit for data processing, which is operatively connected to the manometer by means of connecting elements allowing said processor and said manometer to exchange information flows and also to be positioned within the housing sheath independently one form the other, so as to obtain a device for scuba diving with a modular structure.
Advantageously, therefore, by means of a device for scuba diving carried out with a modular structure according to the present invention, the scuba diver can use a single sheath housing both the processor and the manometer, or either the processor or the manometer, allowing their separate purchase or an independent replacement in case of damage or breakdown.

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION
FIG. 1
shows a first form of embodiment of a device for scuba diving according to the present invention. Said device consists of a sheath
1
on the upper surface of which are two sealed housings
2
and
3
, said housings being respectively meant for two digital displays
4
and
5
: the display
4
belonging to a processor
11
and the display
5
belonging to an electronic manometer
10
. An end of a pipe or intake
6
is fixed to the back portion of said sheath
1
, the other end being connected to a first reducing stage at the output of a bottle
7
, shown in the block diagram in
FIG. 1
a
. Said diagram shows the above-mentioned bottle
7
connected by means of a wire
8
introduced into the intake
6
to a transducer
9
turning pressure signals into voltage signals. Said voltage signals are transferred to a central processing unit
12
belonging to the electronic manometer
10
, which processes the data received from said transducer
9
and shows them on the display
5
, for instance said data can refer to the remaining pressure within the bottle
7
. The central unit
12
of the electronic manometer
10
is connected to a central unit
14
for data processing introduced into the processor
11
by means of a connecting element
13
, which can be an IR-device communicating with corresponding transmission and reception means provided on the electronic manometer
10
and on the processor
11
, a simple electric wire cable, a radio device or others. It is thus possible to carry out a device for scuba diving in which the two main portions it consists of, that is to say, the processor
11
and the electronic manometer
10
, are totally separable and autonomous and can be introduced into the sheath
1
at different times; then by means of the above-mentioned connecting element
13
it is possible to establish a continuous data flow between said portions, so that from the display
5
of the electronic manometer
10
it will be possible to select the visualization of a given set of parameters (for instance those referring to the bottle
7
), while other parameters can be visualized on the display
4
of the processor
11
(for instance the air time, the air consumption, the decompression stages and others).
FIG. 2
shows a second form of embodiment of the present device for scuba diving. As can be observed, the sheath
1
and the display
4
of the processor
11
are wholly similar to those in the form of embodiment described in FIG.
1
. In this variant the electronic manometer
10
has been replaced by a mechanical manometer
17
provided with a sensitive element
19
(
FIG. 2
a
) connected on one end to the bottle
7
and on the other end to a pointer
18
rotatably fixed in the center of a dial
16
of said mechanical manometer
17
. The deformation of the sensitive element
19
due to a pressure variation in the bottle
7
will be detected by the pointer
18
which will rotate on the dial
16
so as to allow the diver to read said pressure variation. As can be observed from the diagram in
FIG. 2
a
, the moving signals of the pointer
18
are turned into voltage signals by a transducer
20
which communicates them to the central unit
14
for data processing of the processor
11
by means of a connecting element
13
previously described. The scuba diver can thus read, as with an ordinary manometer for scuba diving, the remaining pressure of the bottle
7
on the dial
16
, and he or she can simultaneously read in real time the remaining air time on the display
4
of the processor
11
, which has calculated said air time on the basis of the data received from the mechanical manometer
17
. As in the previous form of embodiment, said display
4
can obviously also show other parameters which are useful to the scuba diver during the diving session.
FIGS. 3 and 3
a
show a third form of embodiment of the present computer. As can be observed, a single display
21
is provided on the sheath
1
, said display being used by the CPU
12
and the central unit
14
respectively belonging to an electronic manometer
10
and to a processor
11
, the latter being wholly similar to those described in
FIG. 1
a
. In this case the central processing unit
12
of the electronic manometer
10
is connected by means of a wire
22
to the display
21
, on which it will be obviously possible to read all the data requested by the diver, such as bottle pressure, air time and so on. The use of a single display
21
, therefore, involves the addition of another connection (the wire
22
) between the manometer
10
and the processor
11
, which nevertheless does not alter the modular structure of said computer, allowing in any case the diver to separate said processor
11
and manometer
10
, and representing, where necessary, an improvement in terms of compactness on the diver's instruments.
