Abstract

A tactile alerting or paging system for deaf persons comprises a transmitter which transmits a radio frequency signal when a door-bell push switch is depressed, to a radio receiver carried by the deaf person eg in the manner of a wrist-watch. The receiver output may cause a warning signal in the form of a slight electric shock as Figure 1 embodiment or a tactile warning from an electro-mechanical vibrator as in Figure 2. The transmitter of radio signals and an audible door bell may be combined in a single unit operable by the same push-switch. <IMAGE>

Description

SPECIFICATION Sensory communicator for deaf people Use for which invention is intended Deaf people, especially if living alone in a moderately large dwelling, are often unable to hear callers when an ordinary electric bell is usedr even when wearing hearing aids. Some people have installed visual aids, e.g. flashing lights, in order to overcome this problem. However, it is not possible to be constantly watching these. Deaf people who are also blind have a much more severe problem.

The claims being made with regard to this new device, "Sensory communicator for deaf people", are that the above problems are overcome, and it should prove useful also to the deaf who are also blind.

Description of the invention The sensory communicator consists of a transmitter and a receiver. The transmitter is the doorbell - an ordinary electric bell with coil and electromagnet, but with the circuit modified, to include an oscillator capable of transmitting electromagnetic radiation of low power, and at high frequency, probably at ratio frequencies between about 80 to 110 MHz. The detailed design has to be worked out, and although there are no new principles involved in such a transmitter, the novel part of this component is to combine radio-frequency transmission with a normal audible electric bell with electromagnet.

The receiver consists of a simple radio receiver, omitting the loudspeaker and replacing it by a device which communicates by touch, instead of an audible signal. Two preliminary circuit diagrams are incuded with this description. Although a simple onetransistor radio circuit is shown, the final design will be modified according to established practice, as far as is necessary.

The circuit diagrams accompanying this present description show: a) Electrodes incorporated into the radio receiver circuit, which give a tiny, controlled electric shock to the wearer of the device. The device may be worn on the wrist, and the sensation should be sufficient to alert the deaf person to the presence of a caller, even when lightly sleeping, for example, in a chair.

b) Alternatively to the above, if the transmission of a tiny, harmless electric shock proves not to be feasible in the final design, a mechanical device based on the same principle as the electric bell or electric is to be incorporated into the circuit in place of the electrodes.

The whole device, that is, the receiver, is to be designed so as to be not much larger than a large wristwatch.

This patent is being filed, in advance of the detailed design of the circuit. THis description and diagrams, are, in the present instance, being given primarily to establish a priority date (as in Line 26, Page 5 of "Official Pamphlet" - "Applying for a Patent"). However, no decision has yet been made about "prosecuting all the way to grant" or filing a fresh application in 12 months of the date of the present application. In this period, it is intended to do further work on the design, and the decision will be taken after this work has been done.

CLAIM

1A It is claimed that the invention (SENSORY COMMUNICATOR FOR DEAF PEOPLE) draws the attention of deaf/blind people to callers at the place of residence, whereas similar devices requiring visual attention (such as the installation of flashing lights, connected with the door-bell) would not help people who were both deaf and blind. For people who are deaf but who have normal vision, the invention has some advantages over the system of flashing lights. Flashing lights are often inconvenient because they need the constant attention of the user, whereas this invention requires neither visual attention (inconvenient for anybody except people in waiting-rooms, or working directly near the system) or auditory attention (inconvenient for many deaf people).

1B - Subsidiary Claim to Claim 1A As claimed in Claim 1A, the invention can be used by anyone who needs to be summoned to attention without use of visual or auditory signals; it could be used as a teaching aid for deaf people; for coordinating the activities of musicians; and as a substitute for a radio-paging device for deaf workers.

It is believed that a sensory receiving device as shown in Figure 1 or Figure 2 has not previously been used for the purposes outlined in Claims 1A or 1B.
