摘要:
EMI emissions generated by clock signals in a multi-slot electronic system are reduced by providing out-of-phase clock signals to alternate slots, which cause EMI emissions at typical testing distances and farther to be reduced. An electronic equipment comprises a plurality of slots, each slot operable to receive a clock signal and a plurality of phases of the clock signal, wherein a first phase of the clock signal is routed to a portion of the slots and a second phase of the clock signal is routed to a different portion of the slots. The second phase of the clock signal may be substantially 180° out-of-phase with the first phase of the clock signal.

A method of rendering a graphical object (e.g., 801) on a page (800), is disclosed. A region of the page containing the graphical object (801) is marked as output incompatible based on the graphical object (801) being output incompatible. A bounding box comprising the marked region is determined. A proportion of a number of the regions marked as output incompatible are determined to a total number of regions in the bounding box. A further region within the bounding box is marked as output incompatible to increase the determined proportion above a threshold. The graphical object in the marked region and the further marked region is converted into an output compatible graphical object if the determined proportion is above the threshold. The output compatible graphical object is rendered.

A method of manufacturing a non-volatile memory cell includes forming a first dielectric layer on a substrate. A second dielectric layer having a trench is formed on the first dielectric layer. Thereafter, a pair of charge storage spacers is formed on sidewalls of the trench. A third dielectric layer is then formed over the substrate to cover the first dielectric layer, the charge storage spacers and second dielectric layer. A conductive structure is formed on the third dielectric layer over the charge storage spacers. Subsequently, portions of the third dielectric layer, the second dielectric layer and first dielectric layer not covered by the conductive structure are removed. Ultimately, source/drain regions are formed in the substrate at each side of the conductive structure.

摘要:
An optical parametric oscillator which operates with uncoated optics and a non-linear crystal. The pulse length is long relative to the cavity length, and hence the pump is still operating when the crystal flouresces. The fresnel reflection from the uncoated optics is sufficient to maintain the flouresence. Another aspect attenuates one of the idler and signal beams within the cavity, to allow the other one to emerge more dominant.

摘要:
A communication network access device is adapted for duplex communication and provides transmit and receive signal paths. A controllable socket is coupled to the transmit and receive signal paths and linked to a control interface for activating/deactivating the control interface. A pluggable module is coupled to the transmit and receive signal paths via the controllable socket in an activated status and to a transmission path carrying uni-directional signals. The module includes a first optical device and a splitter in the transmission path and is coupled to a second optical device via the splitter. The second optical device responds to a portion of uni-directional signals provided by the splitter for placing the communication access device in a link up condition for uni-directional signals provided by the first optical device to the transmission path serving an optical local area network.
