Title: Class D amplifier for audio reproduction - is linked to preamplifier by optical coupler and has rectified mains power supply
Inventor: PELTZ GUENTER
IPC: H03F3/217
Filed: 1979-09-28
Abstract: The object of the circuit modification is to simplify the construction of the power amplifier. To achieve this the preamplifier (1), producing a pulse modulated output corresponding to the input signal (E), is coupled to the power amplifier driver (3) through an opto-coupler (2). Using light transmission the input signal to the driver amplifier is galvanically isolated from the preamplifier. This isolation permits the use of a simple power supply comprising a rectifier (4) and smoothing capacitor (C2) directly connected to the ac mains without a transformer. The rectifier can produce an effective voltage of 100V on the loudspeaker circuit from a 220V mains supply. With the employment of complementary FETs (T1,T2) the arrangement enables high power output. It is helpful if VMOS FETs are employed.

Title: Measuring absolute rotation by sagnac effect - using light pulse modulation to reduce errors caused by light scattering
Inventor: RUSSER PETER DR TECHN
IPC: G01C19/72
Filed: 1980-01-18
Abstract: The method of measuring absolute rotations and an associated arrangement involve use of the Sagnac effect whereby light from a monochromatic source is divided and passed in opposite directions around a light path and recombined to a single beam to be fed to a photodetector. The method enables substantial reductions in errors caused by light scattered in the optical conductors and other components. Light from the source (Phi) is pulse modulated. The output of the photodetector (D) is evaluated only during the time intervals in which the light pulses passing directly along the optical path (L) arrive at the photodetector. The duration of the modulation pulse is small compared to the separation interval between pulses. The direct transition time plus the modulation pulse duration are less than the pulse interval.
