Abstract: An apparatus and method for detecting sidewall and dimensional defects in transparent containers includes a laser scanning system (40, 42, 44) positioned astride a conveyor (12) in a production line. In an upstream inspection zone a laser beam vertically scans a portion of the side wall of the container. Photosensors (62, 64, 66, 68) positioned in a detection chamber (56) detect the specific effect which any defect has upon the laser beam by determining the location of light passing through the container and comparing its intensity against pre-set thresholds. A flaw signal is generated when a threshold is exceeded. The number of flaw signals is counted (78) and when the count equals a pre-set value a reject signal is generated (98) to eject the defective container from the conveyor. If a container is not rejected, is passes through a rotator assembly which rotates the container precisely 90 DEG . The container then continues to a similar downstream inspection zone where an indentical scanning and detection process is repeated with regard to the previously uninspected portions of the side wall of the container.

IPC: H04B1/10
Filed: 1988-09-16
Abstract: An improved FM communication system is disclosed in which noise bursts and pops in the audio output of the receiver, due to weak and Rayleigh-faded signals, are minimized by selectively attenuating the audio signal in the receiver. The amount and rate of attenuation for the receiver noise reduction circuits is determined by a control signal derived form either the average discriminator noise at frequencies above 3 kHz, or from a received RF signal strength indicator, or a combination of both. The audio output is attenuated during weak signals or Rayleigh fades only when the attenuation control signal increases above a predetermined signal-to-noise ratio threshold. Also described are further improvements to noise attenuation devices used in combination with the receiver noise reduction circuits to enhance audio quality in particular applications, e.g., FM repeater systems which may incorporate multiple transmitters in a simulcast configuration.
