20120082462 | Low Power Consumption Small Form-Factor Pluggable Transceiver - A method is provided to lower the overall power consumption of small form-factor pluggable (SFP) transceivers. The method includes receiving an indication to operate the SFP transceiver in a low power mode, and setting the SFP transceiver to a low power mode in response to the indication by at least switching off a thermal electric cooler (TEC) that controls a temperature of a laser diode of the SFP transceiver. The proposed method may be implemented whenever a reach is not more than a predetermined distance, for example, 65 kilometers. At such reduced distances, the TEC of the SFP transceiver can be switched off while still guaranteeing link functionality. The instant low power mode has the benefit of reducing the power consumption of the SFP transceiver so that, for example, host platforms with lower power delivery budgets can support the SFP transceiver for at least some applications. | 04-05-2012 |

The transceiver circuit is further configured to process optical receive signals received via the network port. The apparatus further comprises an optical connector configured to provide bi-directional transfer of optical data signals with the host device. | 01-24-2013 |

20120235858 | RADAR APPARATUS CALIBRATION VIA INDIVIDUAL RADAR COMPONENTS - A method, system and computer program product for calibrating and operating a radar apparatus provides for obtaining calibration response data from, for example, a radar cylinder and a plurality of radar columns, prior to assembling the radar cylinder and plurality of radar columns into an assembled radar apparatus. The calibration response data for the exemplary radar cylinder and the plurality of radar columns is evaluated to provide a simulated response of the assembled radar apparatus. Actual measured responses from the assembled radar apparatus may then be correlated with the simulated response through use of a look-up table. The particular method, system and program product for calibrating and operating the radar apparatus provides for avoidance of field calibration of the assembled radar apparatus, which is generally neither desirable nor feasible under hostile conditions. | 09-20-2012 |

20090004918 | RF SHIELDED, SERIES INDUCTOR, HIGH RF POWER IMPEDANCE MATCHING INTERCONNECTOR FOR CO2 SLAB LASER - A RF shielded, series inductor, high power impedance matching network interconnector is provided for connecting an RF power supply to electrodes contained in the shielded, hermetically sealed laser tube housing of a slab laser system. The impedance matching interconnector comprises a short length of co-axial conductor and an impedance matching network that includes two L shaped networks. The inner conductor of the co-axial conductor is connected between the power supply output and the impedance matching network. The outer conductor of the co-axial conductor is grounded. The co-axial conductor has an impedance characteristic to match the power supply output impedance. The first L-shaped network includes a first inductor having a first end connected to the inner conductor of the co-axial conductor and a first capacitor connected to the second end of the first inductor and a second plate connected to ground. The second L shaped network includes a second inductor having a first end connected to the common connection between the second end of the first inductor and the first plate of the first capacitor and a second capacitor having a first plate connected to the second end of the second inductor and a second plate connected to ground. The common connection between the second end of the second inductor and the first plate of the second capacitor is connected through the shielded, hermetically sealed laser tube housing to the electrodes of the slab laser system. The two L-shaped networks may be implemented in a “single capacitor” configuration for lower power applications or in a “multi-capacitor” configuration for higher power applications. | 01-01-2009 |
20090296764 | FREQUENCY-AGILE RF-POWER EXCITATION FOR DRIVING DIFFUSION-COOLED SEALED-OFF, RF-EXCITED GAS LASERS - A gas discharge laser includes a laser housing including a laser gas and an electrode-assembly for lighting a discharge in the laser gas. The electrode assembly has a first resonant frequency when the discharge is not lit and a second resonant frequency when the discharge is lit. RF power delivering circuitry of the laser includes an arrangement for determining and recording the two resonant frequencies. RF power is applied to the electrodes at the first recorded resonant frequency to facilitate lighting of the discharge, and thereafter at the second resonant frequency to light and sustain the discharge. | 12-03-2009 |

A transformer arrangement connects the two transmission-lines to the load. Each transmission-line includes a series-connected pair of twelfth-wave transmission-line sections. The series-connection between the twelfth wave transmission-line sections in one transmission line is connected to the series-connection between the twelfth-wave transmission-line sections in the other by a device having an adjustable impedance. | 04-12-2012 |
20120189031 | GAS LASER DISCHARGE PRE-IONIZATION USING A SIMMER-DISCHARGE - A gas discharge laser including a lasing gas between discharge electrodes and has a power supply for generating RF pulses to be delivered to the electrodes of the laser for energizing the lasing gas. A sequence of RF simmer pulses is delivered to the electrodes. The simmer pulses create sufficient free electrons in the lasing gas to facilitate subsequent ignition of the discharge while not causing laser action. RF lasing pulses having a longer duration than the simmer pulses are delivered to the electrodes to ignite the discharge and provide corresponding laser output pulses. Delivery of the simmer pulses is suspended during delivery of the lasing pulses to avoid amplitude or pulse-width modulation of the laser output pulses by the simmer pulses. | 07-26-2012 |
