Abstract: System for controlling remote apparatuses following the reception of a specific message, consisting of a sequence of characters initially defined by the user, to activate special procedures, for example a reset procedure that returns the program of the entire apparatus to a known initial status. The remote apparatus sends a feedback message to the supervising apparatus confirming that the reset operation has been performed. It can be achieved by means of a specific circuit or by integrating the circuit in new versions of microprocessors or microcontrollers to be marketed.

Abstract: A technique for the allocation and pricing of a resource among n buying agents during an auction bid. A bid sent by each buying agent in the form of a resource demand function si(p) is received, and a datum corresponding to the equilibrium price p* is calculated from the sum S of the n demand functions si(p), by means of the relation: S(p*)=Q. All of the bids received during a predetermined period corresponding to a round of bidding are processed in order to determine the quantity of a resource to be allocated to each buying agent. This is followed by the calculation of the data corresponding to the quantity ai to be allocated for this equilibrium price p* to each buying agent i based on its demand function si such that ai=si(p*). The management system utilizes the calculated data to allocate the corresponding quantities of the resource, and this data is stored in order to calculate the price to be billed to each buying agent.

Abstract: A device for compensating for the nonlinearity of a power amplifier which has a simple configuration and can precisely linearize the transfer characteristics of the power amplifier by predistorting an input signal of the power amplifier. The nonlinearity compensation device of the present invention converts an RF input signal into an IF band rather than a baseband and predistorts the RF input signal in digital domain, and thus any modulation or demodulation process is obviated and the simultaneous processing of signals in multiple channels is facilitated. A first downconverter receives the RF input signal and converts the frequency band of the signal into the IF band to output an IF input signal. A predistortion unit receives and predistorts the IF input signal to compensate for the nonlinearity, and outputs an IF predistorted signal. An upconverter converts the frequency band of the IF predistorted signal into the RF band to provide such a signal to the amplifier.

Abstract: A method of detecting, blind, the coding mode used to encode digital data, for data transmitted in frames of n bits, partially subjected to a convolutional coding. A soft syndrome value is calculated over a sequence of bits representative of a transmission error probability in these bits, and a likelihood value V(&agr;,&bgr;), where &agr;, &bgr; denote the number of coded bits and non-coded bits respectively, is then calculated on the basis of the mean value m and the variance &sgr; of the distribution of the absolute soft syndrome values. The likelihood value V(&agr;,&bgr;) is maximised as a function of &agr; or &bgr; which makes it possible to determine the coding mode used on the basis of the corresponding values &agr; or &bgr;.

A thread manager is provided for the interceptor for the purpose, firstly, of establishing an association between a thread of an object directly consecutive to an incoming request invoking the object and the context of the incoming request as identified by the context manager and, secondly, of recovering the context from the thread manager and associating it with the outgoing request from the object. A method is added to the application management API interface enabling it to recover the current context from the thread manager and to associate it with any thread of the object indirectly consecutive to the incoming request.

Abstract: A radio frequency transmitter, of the type supplied with two signals in baseband and in quadrature, I(nT) and q(nT), which are images from two binary streams representing information to be transmitted, 1) provides a first transposition into the digital domain, at an intermediate frequency &ohgr;0, for the baseband signals and generates, by combination, two signals of intermediate frequency in quadrature, 2) provides a second transposition into the analog domain, after multiplication by a frequency &ohgr;1, followed by a summation of the two signals at intermediate frequency and in quadrature, in such a way that a resultant signal is generated which is found finally around a frequency &ohgr;2, where &ohgr;2=&ohgr;0+&ohgr;1. In an advantageous variant, the radio frequency transmitter additionally digitally compensates gain and phase imperfections of the direct conversion.
