Definitions

• This invention describes a new type of a mobile phone, which can be carried fastened to the wrist of the user and during the phase of conversation, the user can speak and hear at the same time, without removing the device from the place were it is fastened.
• Construction of the Wrist mobile phone can be based on the existing technology that is already used in the existing mobile phones, compared to which however, it brings particular changes and modifications, resulting a substantial change in the way of their usage.
• No 5,224,076 similarly describes a "wristwatch radiotelephone” that brings a telescopically extending mechanism, which can bring the microphone of the device in a distance from the main body of the device, where the speaker is placed in a stable position.
• This device has also to be unfastened from the wrist in order to be used as a telephone. The whole description of this device is substantially differentiated compared to the form of the existing mobile phones.
• Fernandez W.O. Pat. No 6/33569 describes a wrist device that is a combination of two modules, a personal computer and a mobile phone, which are coupled by means of a bracelet. In this device there is not any mechanism (e.g.
• Blonder U.S. Pat. No 5,239,521 describes a "radio telephone in the form of a wristwatch" which has a strap consisted of two layers. The upper layer of the strap brings a speaker and it is connected to the bottom layer in a way that it can be released and rotated, bringing the speaker in the palm and in a distance from a microphone that is found in the bottom strap.
• Chassabian WO Pat. No 98/27702 describes a "wrist-mounted cellular telephone device”. The form of this device is substantially differentiated compared to the form of the existing mobile phones.
• This invention describes an extending of the speaker mechanism, which is consisted of some flat shaped, folded "hinged plates”. Alternatively it describes an ear piece mounted at an end of a tube having a securing arrangement for securing to a finger.
• the key idea of the "wrist mobile phone” is based on the following: a) It bases its construction on the typical form of the existing handheld mobile phones requiring only partial modifications, which though, result substantial changes in the way of their usage, b) It integrates the idea of a wrist mounted telephone devise that allows the user to speak and hear at the same time without removing the device from the wrist, c) It can be easily separated from the straps transforming to a type of a handheld mobile phone.
• Major differences of the "wrist mobile phone” compared to the existing handheld mobile phones are: a) There are one or more straps resembling with those used in the wristwatches, which start from the lateral surfaces of the device. With these straps the "wrist mobile phone” can be fastened to the internal side of the wrist of the user
• the "wrist mobile phone” can be placed directly on the skin of his wrist, or over thin clothes. (For example, it can be placed over a shirt and under the sleeves of a jacket).
• these straps can be connected on a second removable back surface of the device or on the battery of the device, which is placed in the rear part of the device (that facing towards the wrist). In this case the device can be easily separated from the straps, by removing the removable back or by changing the battery with an alternative one which does not bring any straps.
• the straps offer an additional potential except that of carrying the device fastened to the wrist. Straps of a particular construction can incorporate a particularly designed receiving antenna (figure 6).
• this extending mechanism will be briefly called as “retractable antenna (6)” or “antenna (6)".
• the antenna (6) is shortened and the earphone (2) is placed in a special housing which is found in the upper place of the device (element 3, figures 2,3).
• the user wants to set the fastened on his wrist device in the phase of conversation, he extends the antenna (6) (figure 2).
• the earphone (2) is now in a distance of about 10 centimeters from the main body of the device, he leads it with his forefinger towards his ear (figure 1).
• the microphone of the device is placed in the upper surface of the device (element 4, figures 2,3). With this placement the microphone is closer to the mouth of the user, when his finger leads the earphone towards his ear. The user can speak and hear at the same time, without removing the device from the wrist where it is fastened.
• the device is equipped with software, which additionally provides watch services: When the device is in the phase of waiting for a call, the screen shows clearly the time (element 5, figure 3). With this future, the device can replace the traditional watch.
• the "wrist mobile phone” has the following advantages: -The user can speak and hear at the same time, without removing the device from the place where it is placed and carried, (fastened on the wrist), and without using additional accessories. - Hands are free again. Carrying the mobile phone does not keep busy one hand.
• “Wrist mobile phone” is less possible to be stolen or to fall down and to be destroyed.
• the usage of the "wrist mobile phone” induces less exposure of the human brain to the electromagnetic field of the device, compared to the conventional mobile phones. This happens because the main body of the device is not adjacent to the ear during the phase of conversation.
• the receiving antenna can also be removed in a distance from the user's head, if we chose the version of the antenna that is incorporated in the strap.
• the figure 3 represents the device when it is in the phase of waiting for an incoming call:
• the antenna (6) is shortened and the earphone (2) is placed in the special housing (3), which is found in the main body of the device.
• the screen (5) shows the time.
• the figures 1 and 2 represent the device when it is in the phase of conversation.
• the figure 4 represents how the earphone is electronically connected with the main body of the device, through the tract of the retractable antenna (6). (Approximate configuration. Exact ratios of the dimensions are not considered).
• the figure 5 represents how the device is fastened to the wrist.
• the figure 6 represents the particularly constructed strap, which incorporates a receiving antenna.
• Construction of the "wrist mobile phone” can be based on the existing technology. In the figure 3 an approximate ratio of 1 : 1 ,8 is used. The dimensions of the existing mobile phone MOTOROLA Star Tag 110 (94x55x19) were considered.
• the form of the "wrist mobile phone” is similar to the typical form of the most of the existing mobile phones (parallelepiped consisted of six sides).
• the two large surfaces (the front one and the rear one) are not completely flat, but they have a slightly bent form (lengthways their longer dimension). Consequently to this slightly bent form, the device has a better match to the wrist of the user, slightly surrounding it.
• the exact size of the "wrist mobile phone” will be depended on the electronic technology on which its construction will be based on. We can compare the size of the "wrist mobile phone” to the size of the existing mobile phones, because the “wrist mobile phone” does not require any further volume. In contrary, there is a decrease of the size due to the fact that in the "wrist mobile phone” there is not any incorporated speaker. A further decrease of the size can be achieved if the version of the antenna that is incorporated to the strap will be established, instead of the antenna that is incorporated to the main body of the device. (Concerning the receiving antenna, the device offers three alternative possibilities, which are described below).
• the incorporated speaker is replaced by a small earphone (2), resembling in the form and size to those which are used in the Walkman.
• This earphone is permanently connected through a joint (7), with the top of the antenna (6), which is extended from the upper surface of the device (figure 2).
• This antenna (6) is consisted of one or two or more retracting parts of a hollow tube. This tube is consisted of a semi-flexible (but not very flexible) conductible material.
• the earphone (2), which is placed in the top of the antenna (6), is wired with the main body of the device, through a very thin wire, which is found across the internal tract of the antenna (6).
• the wiring of the earphone can be incorporated in the wall of the antenna, across its retracting parts.
• Two conductible lines e.g. made by copper
• These conductible lines are pasted on the internal tract of the antenna (6).
• an insulating material (element 10).
• the earphone (2) will be connected with the upper end of the antenna (6) through a joint (figure 2, element 7), that will allow the movement of the earphone (2) upwards or downwards with regard to the oblong axis of the antenna (6). Consequently, during the phase of listening, the user will be able to change the inclination of his wrist with regard to the position of his head, while the earphone (2) is in his ear. This event, in combination with the semi-flexibility of the antenna (6), offers convenience and relative freedom of the movements of the hand that wears the phone, during listening.
• the volume of the sound of the earphone (2) will be adjusted by the keys of the main body of the device. Nevertheless, in an advanced version of this earphone, there could be an incorporated volume controller, which could offer an additional ability to adjust the volume of the sound using the forefinger:
• In the ridge (backside) of the earphone (2) there will be a small controller, which will have the form of a wheel, which is placed vertically and semi-sunken in the body of the earphone (figure 2, element 15).
• the keys and the screen will be placed on the front surface of the device in a similar way as in the existing mobile phones. There are the following small differences: The screen (5) is placed in about 10-cm distance bellow the upper end of the front surface of the device (figure 3).
• the activation of the device from the waiting phase to the conversation phase is accomplished automatically, when the antenna (6) is extended.
• B) Extension of the antenna (6) can be accomplished with the assistance of a spring that is found in the track of the antenna. During the waiting phase, the antenna (6) is retracted and it is retained in this place by a mechanical manner.
• the "activation key” (5) has a large size (about 0,8-cm diameter). In any case, the fingers of the other hand can also press this key. The retraction of the antenna can be accomplished by double clicking on the same key (5).
• the antenna (6) has to correspond to the forefinger and the "activation key" (5) to the little finger of the hand that brings the device, it is obvious that there have to be two different versions of the "wrist mobile phones”: for the left and for the right hand.
• the several elements that form the front surface of the device of the "wrist mobile phone for the left hand” will have a “mirror” position compared to those of the "wrist mobile phone for the right hand".
• the lower coating (17) e.g. made of thin leather
• a thin and flexible metal plaque, (18) e.g. made of copper
• a thin insulation (19) that will came in between the described as above metal plaque and the antenna
• the antenna itself This may have the form of a thin, flexible oblong lamina that will lie all along the length of the strap (figure 6, element 20). Alternatively it will have the form of an externally insulated thin wire that will run across the strap in a vertical direction compared to its oblong axis, from one side of the strap to the other, forming multiple folding of S type (figure 6, element 21).
• the upper coating (22) (e.g. made of thin leather).
• the straps described as above fit together with the main body of the device through a mechanism similar to those used in the straps of the watches. This junction also provides an appropriate adjustment of the two poles of the antenna that project from the end of the strap, with the corresponding terminals that are found on the surface of the body of the device in this particular place (figure 6, element 23).
• An accessory strap can replace the entire original strap.
• the advantage of choosing the type of antenna that is incorporated in the strap is that there is less exposure of the brain to the electromagnetic waves, as this type of antenna is found in a distance from the brain of the user. Furthermore, during the phase of conversation, the antenna of this type is found in a position that is not surrounded by parts of the body of the user. Consequently it has a better signal receiving ability.
• the retractable mechanism that serves for extending the earphone (2) is again similar to the retractable antenna (6), but it does not play the role of a receiving antenna. Consequently, there is no need to be made of a conductible material.
• the straps that serve for fastening the "wrist mobile phone" on the user's wrist they will have an external appearance resembling to the straps of the watches, either they are of a particular construction and they incorporate an antenna or they are simple (element 1, figures 1,2,3).
• These straps fit together with the main body of the device through a mechanism similar to those used in the straps of the watches: In the side surfaces of the device there are some small projections, two for each strap. Between them there is an axis to which the strap is adjusted (element 14, figure 5). This axis can be removed from its original position and consequently the strap can change with an accessory one.
• the straps will have to have an adjustable length, so that the device will be able to be wearied either directly on the skin or over some clothes. For this reason, the straps will lock to each other with a bolt, preferably of velctron type, (without excluding alternative ways, as the traditional way that the straps of the watches lock to each other).
• the removable battery of the "wrist mobile phone” will be placed in the rear place of the device, which touches the hand of the user. ( Figure 5, element 12).
• the battery can be removed after untying the device from the wrist.
• the battery will come in between this second "back” and the main body of the device.
• an other choice is that the system of the straps will be connected directly on the battery that is found in the rear place of the device. If we want to rid the device of the straps, we change the battery with an alternative one that does not bring any straps.
