Patent CA-2206044-A1 (CA)
Title: Removing low frequency interference in a digital fm receiver
Inventor: CROFT THOMAS M
IPC: G01N27/12
Filed: 1995-11-28
Abstract: In a digital FM receiver having a demodulator that receives a radio signal and generates therefrom a phase sample whose behavior determines an output of the demodulator, an apparatus for removing a low-frequency interference signal from the phase sample converts the phase sample into a frequency sample which is then high-pass filtered to produce a filtered frequency sample. The filtered frequency sample is then converted into a filtered phase sample, which may be further demodulated in accordance with known techniques. Converting the phase sample into a frequency sample may be performed by a first order difference circuit. Converting the filtered frequency sample into the filtered phase sample may be performed by an integrator. Because the demodulator may produce degraded performance when the inventive apparatus is applied to a radio signal that does not have low-frequency interference, in another aspect of the invention the demodulator is further provided with a circuit for detecting the presence of the low-frequency interference signal in the radio signal, and alternatively selecting, in response thereto, either the filtered or original phase sample to be supplied to further demodulation circuitry. Several methods of detecting the presence of the low-frequency interference signal are disclosed.

Abstract: Pour la confection manuelle des vêtements, il est d'usage courant de tailler les tissus en se servant de patrons. Il est cependant nécessaire de donner au tissu découpé une grandeur supérieure à celle du patron pour coudre les deux pièces, avant et arrière, du vêtement à confectionner. La marge additionnelle de tissu est délimitée habituellement en traçant sur le tissu une ligne parallèle au patron. Par la suite, le tissu est découpé en suivant cette ligne. La présente invention permet de délimiter la marge additionnelle requise en même temps que l'on fait la coupe du tissu. Il s'agit d'un guide-ciseaux qui est fixé à la lame droite d'une paire de ciseaux au moyen d'un aimant. Ce guide-ciseaux permet de délimiter la marge additionnelle nécessaire en même temps que l'on coupe le tissu car il est placé entre la lame droite de la paire de ciseaux et la bordure du patron.
