Title: Localization method and apparatus
IPC: G01D5/26
Filed: 1991-06-21
Abstract: The invention relates to a localization method, according to which a light beam emitted by a modulable light source impinges on a photosensitive layer at a particular location and the impingement location of that beam on that layer is derived from two photocurrents of opposite direction, which are generated by that beam in that layer and which are converted into modulated signals. These signals are alternately processed and used to alternately modulate the light source. The invention also relates to an apparatus for implementing this method which, for the purpose of measuring the photocurrents, comprises a commutator circuit by means of which one of the photocurrents at a time is conducted to a current-to- voltage converter, and further comprises a voltage- controlled oscillator in series with said current-to- voltage converter, the light source being modulated by the output signal of the said oscillator.

Title: Delta-sigma modulator with switched capacitor implemmentation
IPC: H03M3/00
Filed: 1983-01-20
Abstract: A Delta-Sigma modulator for one-bit analog to digital conversion of a signal (U(t)), such as a telephone voice channel signal to digital form is disclosed. The voice signal is sampled (1, 3, C<sub>1</sub>) at a rate high compared to the highest voice channel frequency component. Sampled instantaneous signal values are integrated (4, C<sub>3</sub>), re-sampled (10, 12, C<sub>4</sub>) and again integrated (17, C<sub>6</sub>) to reduce encoding noise. Finally, a bi-level sense identifying circuit (19) links the second integrator output to a D type flip-flop (20) providing the one-bit encoder output (b(n)).The sampling and integrator control is effected by switching in a capacitor charge shifting arrangement under clock control and feedback is applied as a capacitor switching program modification (301, 302).

Inventor: SEITZ THOMAS
IPC: H01F38/28
Filed: 1986-12-15
Abstract: A measuring transformer for measuring a current flowing in an electrical conductor is disclosed. Illustratively, the transformer comprises a three legged ferromagnetic core whose center leg at least partially surrounded by the electrical conductor. The center leg defines a center air gap and two outer air gaps, the center gap containing a magnetic field snesor and one outer gap being located at each end of the center leg. The two outer gaps are longer than the center gap when measured in the longitudinal direction of the center leg. The center leg and the magnetic sensor may form a single construction element. This configuration permits an especially precise, simple, and dependable installation of the measuring transformer, without worsening non-linearities or phase errors, while improving air-gap tolerances.
