Abstract: The disclosure relates to a method of synchronising a device for receiving scrambled data, using at least one periodic scrambling sequence which is divided into K time intervals, each interval comprising N bit periods known as symbols. In particular, one such method includes calculating a synchronisation value of at least one polynomial that generates the aforementioned scrambling sequence within a pre-determined synchronisation time interval and synchronisation bit period. During the calculation step, the sequence is progressed through at increments of at least one time interval and at least one bit period, using a matrix calculation of the synchronisation value.

Abstract: A cellular radiotelephone signal is disclosed of the type that includes a main symmetrical bi-directional channel comprising a main up-link and a main down-link for the low- or medium-speed transmission of signaling and control information and data; and at least one supplementary channel which is assigned solely to the down-link and which is intended for high-speed data transmission using a multi-carrier technique, which ensures that the data are distributed over frequency/time space and which is structured in the form of pre-defined entities.

Abstract: Disclosed is a device and method for intelligently heating a component of a printed circuit board (PCB) to bring it within a specified operating temperature range quickly. A temperature sensor positioned in proximity to the component and is coupled with a logic circuit that receives a reading from the temperature sensor and compares it to a threshold temperature value. A heating element positioned in proximity to the component is coupled with a power source and a switch. The switch is triggered by the logic circuit to activate the heating element when the temperature sensor reading is cooler than the threshold temperature value thereby causing the component to warm up. The switch is triggered again by the logic circuit to de-activate the heating element when the temperature sensor reaches the threshold temperature value or a predetermined timeout period expires.
