Abstract: Voice-activity detection method for determining the existence of voice signals in a telephone signal where can also exist one or two frequency tones comprising the steps of:
     computing the value of the ratio,      where Amax corresponds to the maximum value of the received signal during a sampling window and E a measure of the energy,   comparing said computed ratio to a first determined threshold value,   reporting the existence of a unique tone when said ratio appears to be lower than said first threshold value.   
     Additionaly, the calculated value is compared to a second threshold value and if it appears to be inferior to the latter, there will be reported the existence of a dual-tone in the received signal. Conversely, if the ratio is superior to that second threshold value, the process will conclude on the existence of some voice-activity, assuming the level of the received signal is superior to - 43 dB. 
     Preferably, the determination of the single or dual tone signals comprises the steps of:
     computing (201) the value of the energy of the signal,   processing (201) said received signal to determine the existence of one or two tones in said signal,   applying a second-order or fourth-order autoregressive process in response to said determination and performing (203, 208) a first estimation of the autoregressive parameters of said received signal,   performing a digital band-pass filtering operation (205,210) adjusted to the result of the estimation of said autoregressive parameters to provide a partial elimination of the noise existing on said received signal,   reapplying (205, 210) a second-order or fourth-order autoregressive process in response to said determination and performing a final estimation of the autoregressive parameters of said received signal,   computing (206, 211) the values of the frequencies each tone from the value of said estimated parameters.   
     The first and final second-order autoregressive process are based on the predicting function having the z-transfer function:       
 and which is associated with a Least Mean Square algorithm continuously adapting the parameters of the predictor in a sense allowing the minimizing of an error signal. On the other hand, the first and final fourth-order autoregressive process are based on the predicting function having the z-transfer function:

Abstract: A bidirectional radio system for low cost, high through-put accumulation of data from a large number of site units. The site units are connected to remote radio transceivers in radio communication with a plurality of base stations. Accurate frequency synchronization allows multiple carriers within a 12.5 kHz FCC bandwidth. Frequency synchronization is achieved at low cost by transmitting a high accuracy carrier and clock signal at a base station, and using receiving circuitry a remote stations to extract the base clock signal and base carrier frequency and a phase-lock loop to stabilize the remote station carriers. The reception circuitry at a remote station provides independent carrier frequency and clock rate recovery, a phase-lock loop at baseband, and a coarse clock rate recovery circuit coupled to a fine clock rate recovery circuit. Remote station responses are time domain multiplexed. A base station receiver can decode a very short remote station response by scaling the response with the phase and amplitude of an initial segment of the response. Spatial reuse of carrier frequencies further increases the rate of data through-put.

Abstract: The compression algorithms are based on block processing, and the images are of three types, namely "intra" images, "predicted" images and interpolated or "bidirectional" images (B). According to the invention, the memory space of the decoder is organised into five pages, four pages of which are each used to store one image frame of intra or predicted type, and the fifth is divided into areas capable of containing one line of blocks (for example "B2 No. p" indicates the line of blocks number p of an image B No. 2). The bidirectional images being decoded by successive steps of one line of blocks at a time, the lines of blocks in the course of decoding are placed in step at the address on each occasion, in the fifth page, of a line of blocks, the content of which has already been displayed. For example, a line of blocks (B1 No. n-6) which was placed before B2 No. p has already been displaced, and the memory area (------) is therefore free. Applications: digital television. <IMAGE>

Abstract: A method for refining triglyceride oils, preferably of natural origin. The method is particularly suitable for the refining of oils meant for direct consumption such as are sunflower oil, palm oil and olive oil. The method consists of a two-step treatment comprising a heating treatment and a subsequent stripping treatment. The stripping temperature is at 30-200  DEG C and the heating treatment consists of keeping the oil at an elevated but moderate temperature (30-180  DEG C). A stable oil results, which may be characterized further either by a specific flavour profile which may be appraised as natural and attractive or by the absence of any flavour.
