  • Patent number: 8786195
    Abstract: Driving a light-emitting element by a driver capable of testing at least an open or short condition of the light-emitting element. In particular, a driving signal is generated to drive the light-emitting element. It is evaluated based on the value of the driving signal whether a predetermined condition is reached. If so, a latch signal is output indicating that the testing has finished.

  • Patent number: 8786396
    Abstract: A heater design for post-process trimming of thin-film transistors is described. The heater incorporates low sheet-resistance material deposited in non-active connecting regions of the heater to reduce heat generation and power consumption in areas distant from active heating members of the heater. The heating members are proximal to a thin-film resistor. The resistance of the thin-film resistor can be trimmed permanently to a desired value by applying short current pulses to the heater. Optimization of a heater design is described. Trimming currents can be as low as 20 mA.

  • Patent number: 8789085
    Abstract: A method for detecting the presence of pornographic contents in a sequence of video frames having associated respective motion vectors, includes identifying groups of motion vectors having similar orientation and the presence, in subsequent frames of the sequence, of motion types defined by affiliated groups of motion vectors having homologous motion characteristics in subsequent frames. Thereafter, detection in these motion types of the occurrence of negative affiliations representative of an inversion in the motion of the respective group of vectors. If the number of such negative affiliations counted at a given interval reaches a given count threshold, identified in the sequence of frames is a periodic motion susceptible of having pornographic content. Repetition of the periodic motions may be verified, the image sequence identified as susceptible to having pornographic contents and/or subjected to an optional verification procedure such as “skin detection” type, and transmission may be blocked.
