Abstract

The infra-red telephone handset replaces the wires usually used to connect a handset to the transceiver unit with an infra-red transmission device.

Description

Bez: Drehtloser Telefonhörer (Infrarot-Hörer) Drahtloser Telefonhörer (Infrarot-Hörer) Die Erfindung betrifft ein Telefon, welches mit drahtlosen Hörer ausgestattet ist, wobei der Empfang und die Sendung mittels Inrarot-Strahlen übersandt werden.Bez: Rotary telephone receiver (infrared receiver) Wireless telephone receiver (Infrared handset) The invention relates to a telephone with a wireless handset is equipped, the reception and the transmission being transmitted by means of infrared rays will.

Die Form des Apparates ist dabei völlig gleichgültig; sie soll nur zweckdienlich sein. Der Apparat selbst kann entweder mit der herkömmlichen Nummernscheibe oder bereits schon mit den neueren Nummern-Tasten ausgestattet sein. The form of the apparatus is completely indifferent; she should only be expedient. The device itself can either use the conventional dial or already be equipped with the newer number buttons.

Der Zweck dieser Neuerung hat wohl eindeutig vielfältige Vorteile, die hier nicht näher erläutert werden brauchen. The purpose of this innovation clearly has multiple advantages, which do not need to be explained in more detail here.

Es ist zwar schon eine Vielzahl von drahtlosen Mikrofonen, Sprechanlagen u. dgl. entwickelt worden Jedoch oin Telefon mit drahtlosem Hörer - welches auf Infrarot-Strahlung arbeitet - noch nicht! Deshalb ist es an der Zeit, daß den Menschen, sowohl im beruflichen wie auch im privaten Bereich zu seiner Erleichterung wie auch BequemlichkeSt; dies Erfindung zu seiner Verfugung gestellt wird. While there is already a wide variety of wireless microphones, intercoms and the like have been developed, however, in a telephone with a wireless handset - which on Infrared radiation works - not yet! Therefore it is time that the people both in the professional as well as in the private area to his relief as well Convenience; this invention is made available to him.
