Title: Input data operated dental surgery chair assembly - has input data microphone near surgeon, with computer controlled speech input
IPC: A61G15/14
Filed: 1980-08-29
Abstract: The complex dental chair assembly is operated by commands and/or data, supplied through appropriate input (3) by the dentist. The input is provided by at least one microphone (31) in close vicinity to the dentist, to which is connected a computer controlled speech input (32). The latter recognises individual spoken words and translates them into mechanically related control commands and/or data. Pref. the microphone can be activated by an additional switch (4), possibly of a contactless proximity type. The microphone may be arranged on the patient's chair headrest, into which it may be inserted or pivoted. These movements may provide the microphone activation. Its state may be optically or acoustically indicated. There may be also an indication for the data and/or commands. The microphone may have a radio connection to the speech input device.

Title: HI=FI stereophonic tape recorder integrated circuit amplifier - uses additional transistor pairs between intermediate and final stages
Inventor: ANDRIANOV VITALIJ VASILEVIC
IPC: H03F3/68
Filed: 1980-10-03
Abstract: An integrated circuit amplifier, esp. applicable to the magnetic recording and reproduction of electrical signals, e.g. stereophonic tape recording, produces improved reproduction using a new circuit arrangement which also produces a higher yield in mass production. Two series transistor pairs (22,23; 24,25) are connected between the intermediate (5) and final (6) stages of each channel. Each output stage transistor (18,19) is driven from the junction of one pair of opposite type. The transistors (22,25) of the pairs which are not driven from the output of the intermediate circuit have base-emitter paths parallel with those of the intermediate circuit dynamic load (15) and its output transistor (14). The collectors of the transistors (23,24) driven from the intermediate circuit output are connected to the supply rails (26,27) corresp. to their type.

Title: Audiometer
Inventor: HELLE ROLAND DR ING
IPC: H04R25/02
Filed: 1981-04-06
Abstract: The invention relates to an audiometer having a sound generator whose spectral composition and/or level can be adjusted (2, 3), and a display (40) for these values which are fed to the ear (51) via one or more electroacoustic transducers (29', 30', 33). When examining hearing in this way, the problem has arisen that sometimes the sound value set and displayed does not arrive at the ear. Such a defect can lead to erroneous diagnoses. The invention therefore provides to coordinate the setting, test sound and display. Provision is made for this purpose of a probe (29'', 30'', 32' and 50) which is effective at the ear (51), and the display (26') and the sound actually fed to the ear by the transducer (29', 30', 33) is coordinated with the signal of the probe. The probe can be used, for example, also to determine the undesired noise arriving at the ear, for example during breaks in the measurement, and, if appropriate, to prevent a deleterious influence on the measurement. An audiometer improved in accordance with the invention is particularly suitable for automatic setting of audiograms. <IMAGE>

IPC: H04L27/00
Filed: 1981-04-30
Abstract: In a multi-phase modulation method in which digital words each having a word length of at least 3 bits control the generation of a modulated carrier in a manner such that each digital word value is associated with a particular amplitude and phase of the modulated carrier, and in which the modulated carrier is formed of a combination of three oscillating signals having identical frequencies, shifted in phase by 120 DEG  relative to one another, and each having a selected amplitude, the digital words are associated with the oscillating signals in such a manner that a first group of digital words is represented only by modulated carrier phases which possess equal angular spacings in the 360 DEG  phase plane and a plurality of further digital words is represented by a zero amplitude carrier formed by combining all three oscillating signals each having the identical selected amplitude or by suppressing all three oscillating signals.

Title: Analog/digital converter
Inventor: HENRY TIM W
IPC: H03M1/00
Filed: 1981-07-25
Abstract: An A/D converter for generating a digital Gray code signal from an analog signal having a particular rate of change contains a coding device which, responding to the analog signal, outputs an output signal of coding voltages in bit-parallel form from a lowest-order bit to a highest-order bit. The coded voltages represent the amplitude of the applied analog signal. Responding to the coding voltages, an amplifier device outputs an output signal in bit-parallel form in such a manner that when the rate of change increases, the bit accuracy increases from the lowest-order up to the highest-order bit.

Filed: 1981-11-17
Abstract: In a heating installation for hot-water preparation, a heating device (1) is provided, from which heated water is supplied to a storage tank (3, 4). Inserted into the forward run pipe (5) to the storage tank (3) is a flow control valve or a three-way valve (30), the flow in the forward run pipe (5) being released in a temperature-controlled manner. Thus, only water which is heated to a preselectable temperature is supplied to the storage tank (3), so that the latter is filled with hot water in a layered manner from the top.
