20100157493 | ELECTROSTATIC DISCHARGE PROTECTION CIRCUIT - An integrated circuit includes an electrostatic discharge (ESD) detection circuit which detects an ESD event and generates an event signal. In response to that event signal, a control circuit controls the operation of a buffer circuit to function in an additional mode wherein the normal differential operation of the buffer circuit is disabled and the buffer circuit is instead configured to form a conduction path between supply rails to discharge the ESD event. Preferably, a plurality of buffer circuits are driven in parallel by the control circuit to function in the additional mode to form parallel discharge paths for the ESD event. Multiple ESD detection circuits may be provided, and any one of those detection circuits can trigger the control circuitry to place all of the buffer circuits in the additional mode. | 06-24-2010 |

20090152587 | DEEP GUARD REGIONS FOR REDUCING LATCH-UP IN ELECTRONICS DEVICES - An embodiment of an integrated circuit includes a semiconductor layer, a well, first and second source/drain regions, and a guard region. The semiconductor layer has a first conductivity, and the well is disposed in the layer and has a second conductivity. The first source/drain region is formed in the well and has the first conductivity, and the second source/drain region is formed in the layer outside of the well and has the second conductivity. The guard region is disposed in the layer between the well and the second source/drain region and has the second conductivity. The guard region may prevent latch up by inhibiting the triggering of a silicon-controlled rectifier (SCR) having one of the first and second source/drain regions as an anode and the other of the first and second source/drain regions as a cathode. | 06-18-2009 |

20080289642 | SYSTEM FOR PRODUCING AND PACKING ARTICLES - A cigarette manufacturing and packing system having a connecting unit connected to a data-gathering computer; a sensor device for detecting a code identifying a work material; and a signalling device for emitting a signal relative to an instant the work material starts to be used; the connecting unit acts as a server to make available to the data-gathering computer, for a given length of time, the data received from the sensor device and the signalling device. | 11-27-2008 |
20100085413 | Laser Packet Marking Unit - A laser marking unit for marking packets, having: a marking conveyor for feeding the packets successively along a marking path; and a marking station located along the marking conveyor, and having a laser marking device for marking a code on the outer surface of each packet conveyed on the marking conveyor. The laser marking device has a laser beam generator which emits a laser beam by means of an emitter; and a deflection box which deflects the laser beam onto the packet at the marking station by directing the laser beam along a focusing path that starts at the emitter and terminates on the outer surface of the packet. | 04-08-2010 |
