Abstract: A fault checker system for an X-ray detector, comprising an input interface (IN) for receiving readings acquired by a target detector pixel not exposed to X-radiation. A converter (CV) is configured to convert the readings into a metric. A thresholder (CP) is configured to compare the metric against at least one threshold and, based on the comparing, provide an indication on whether the detector pixel is faulty.

Abstract: An electroabsorption modulated laser (EML) which uses coupling for chirp correction is disclosed.

Abstract: An optical radiation amplifier, including an input port which receives the optical radiation and a first semiconductor optical amplifier (SOA), which is coupled to receive the optical radiation from the input port and is adapted to amplify the optical radiation to produce amplified optical radiation in response to a first current injected into the first SOA. The amplifier also includes an electro-absorption modulator (EAM), which is coupled to receive the amplified optical radiation and is adapted to modulate the amplified optical radiation in response to a modulation voltage applied to the EAM so as to produce modulated radiation. There is a second SOA, which is coupled to receive the modulated radiation and is adapted to amplify the modulated radiation in response to a second current injected into the second SOA.

Abstract: A method for programming an NROM cell which includes the steps of applying a drain, a source and a gate voltage to the cell and verifying a programmed or a non-programmed state of the cell. If the cell is in the non-programmed state, the method includes the steps of increasing the drain voltage and maintaining the gate voltage at a constant level during at least a part of the step of increasing. The steps of applying, verifying, increasing and maintaining are repeated until the cell reaches the programmed state.

Abstract: A multiprocessor programmable interrupt controller (MPIC) system has an interrupt bus, distinct from the system (memory) bus, for handling interrupt-related messages. I/O device interrupt lines are connected to one or more interrupt delivery units (IDUs) that are each coupled to the interrupt bus for broadcasting of I/O-generated interrupt request messages. Each processor chip has an on-board interrupt acceptance unit (IAU) that can accept interrupt requests from the interrupt bus and can broadcast on the interrupt bus interrupt request messages generated by its associated processor. Each processor can request to read the contents of the IAU control registers that are associated with another target processor. In that case, a remote read request message is generated by the IAU of the local processor and responded to, without software intervention, by the IAU of the target processor. A remote read status field indicates to the local processor the status of the data contained in a remote read register.
