Title: Wireless local area network

Filed: 1989-09-28
Granted: 1993-01-12
Abstract: ABSTRACT OF THE DISCLOSURE In a wireless local area network in which data packets are spread spectrum encoded, method and apparatus are provided for determining phase values that synchronize noise codes at network stations with received data packets. A synchronizing packet is first transmitted from a source station to various network stations. Each network station performs a wide-range search for a phase value that synchronizes the noise code of the station with the synchronizing packet. Thereafter, each network station performs narrow-range searches for phase values synchronizing the noise code of the station with subsequently received network packets. The stations switch to the wide-range search mode whenever a synchronizing phase angle has not been detected for predetermined period of time and switch to a narrow-range search mode whenever a synchronizing phase angle is detected. In a polled local area network, polling packets generated by a base station serve as synchronizing packets, and the base station is adapted to perform only narrow-range searches. Packets with shorter synchronization headers can be used thereby improving data transfer rates.

Abstract: Apparatus and a method for removing suspended particles from water in a circular tank having a distribution and flocculation chamber immersed in the tank of water and carried circularly around the tank by a carriage. Flocculating material and inlet water are introduced into the body of water from the moving flocculating chamber at the same rate as clarified water is discharged through a filter substantially covering the bottom of the tank. A majority of particles in the water is collected by flocs in the water and floated to the water surface by air bubble action. The floating sludge is removed by a spiral scoop carried by the carriage. The water is then passed through the bottom filter which removes the remaining flocs completing the clarification of the water for discharge. Apparatus is provided for selectively back washing sections of the filter while the remainder of the filter is in operation.

Abstract: An analog digital conversion is provided for two color difference signals, for example for a recording according to a timeplex method. The color difference signals are adjusted in their amplitude at the input of the analog digital converter such that the modulation range of the analog digital converter is always fully used independent of the original amplitude of the color difference signal. The amplitude is restored back to its original value after a digital to analog reconversion. This results in an improvement of the signal to noise ratio during the transmission. The amplification provided to the various signals can be controlled by comparator circuits comparing the signal level with a reference signal.
