摘要： The most popular method for reducing stray emission effects in a cathode ray tube is to install a bleeder resistor at the flyback transformer of the tube. Such a bleeder resistor is, however, quite expensive. Therefore, the stray emission reduction circuit according to the invention differentiates the H pulse when the TV set is switched from "on" to "standby" which results in a higher duty cycle of the control transistor, implying a lower duty cycle of the horizontal output transistor HOT. This results in a lower voltage at the tuning capacitor and hence lowers the flyback peak voltage at the anode. This results in a drop of the EHT voltage.

摘要： The invention relates to a switch mode power supply (SMPS) comprising control means (IP1) including an oscillator (OS) for generating a pulse-width modulated signal (V2). The object is to provide a fast start-up time over a wide mains input-voltage range (AC). According to the invention, the switch mode power supply comprises a network (T2, R52, R51, R24) which provides in case of a high input voltage a soft start with a low oscillating frequency and in case of low input voltage a start-up with essentially the normal oscillating frequency.

The network includes a transistor (T2) used in inverse mode as a switching element which provides a threshold value of about 150 Volt. The power supply can be used advantageously as part of a TV receiver.

摘要： This system for illuminating a liquid-crystal screen comprises a light source which emits an unpolarized light beam (F). A polarizing splitter device (PBS) receives this unpolarized light beam and retransmits, onto the liquid-crystal screen, a first and a second beam (F1, F2) which are polarized in the same polarization direction. The axes of the two beams make a defined angle (2.beta.) between them. A matrix of microlenses is provided with one microlens (.mu.L) for at least two adjacent picture elements (EL1, EL2) in the liquid-crystal screen. Each microlens directs that part of the first beam which it receives onto one (EL1) of the two picture elements and that part of the second beam which it receives onto the other picture element (EL2).

摘要： An adaptive trellis decoder seamlessly switches between multiple operational modes. The trellis decoder employs a code sequence detection system that detects codes in input interleaved packet data. The code sequence detection system also reduces the delay (latency) between the input of encoded data and the output of decoded data. The code sequence detection system processes video data in the form of groups of interleaved trellis encoded data packets and includes a traceback network that identifies a sequence of antecedent trellis states, in accordance with a state transition trellis. The traceback network identifies the antecedent states for collocated interleaved packets in response to decision data associated with trellis state transitions. Output trellis decoded data is provided in response to the identified sequence of antecedent trellis states. The decoder can also provide a plurality of trellis decoded data sequences. The decoded data sequences are provided by identifying corresponding antecedent trellis state sequences with delayed decision data in accordance with a state transition trellis. One of the decoded data sequences is identified with a pointer updated by identifying antecedent trellis states with the decision data.
