| 20090034465 | METHOD AND SYSTEM FOR DIMENSIONING SCHEDULING ASSIGNMENTS IN A COMMUNICATION SYSTEM - A system and method for performing Scheduling Assignments (SAs) for User Equipments (UEs) at a base station of a communication system by accounting for the different operating conditions UEs may experience or for the different data rates or data packet sizes UEs may require. This reduces a total size of SAs by introducing compact SAs, in addition to full SAs. For compact SAs, the range for the resource allocation or for the spectral efficiency of the signal transmission is restricted or some fields that exist in the full SA are eliminated without adversely impacting scheduling flexibility or system throughput. By reducing the total size of SAs through the use of compact SAs, the corresponding control signaling overhead is reduced, which improves system throughput, improves scheduling flexibility, or improves coverage. | 2009-02-05 |

Based on the one or more symbol indices a set of possible start symbol indices is established. Thereafter, a frame is received comprising one or more of a preamble symbol, a first zone and the second zone. It is determined if the received frame comprises the second zone. If the second zone is present in the received frame, the start symbol index of the second zone of the received frame is determined based on the detection of one or more codes and the set of possible start symbol indices.

| 20090034559 | VIDEO APPARATUS HAVING PVR FUNCTION AND CONTROL METHOD THEREOF - A video apparatus having a personal video recorder (PVR) function and a control method thereof are provided. The video apparatus includes a counter which assigns a timestamp to a transport stream packet, a synchronization unit which extracts time information from the transport stream packet, compares the extracted time information with system time information of the video apparatus, and outputs synchronization control information, and a controller which stores an information table created using the timestamp and synchronization control information. | 2009-02-05 |
| 20090034560 | Generating And Operating A Double Temporal Descriptor For Transmitting A Synchronizing Signal In A Packet Network - The invention concerns device for transmitting packets in a packet communication network comprising at least two stations, including in particular means for generating a first temporal descriptor from a sampled value of a master counter, means for generating a second temporal descriptor from a sampled value of a second counter synchronized on all the network stations and means for transmitting jointly the two temporal descriptors in the network. The invention also concerns a device for receiving packets in a packet communication network, which uses the double temporal descriptor generated by the transmitter device. | 2009-02-05 |

| 20090034562 | Visible continuum generation utilizing a hybrid optical source - An all-fiber supercontinuum source is formed as a hybrid combination of a first section of continuum-generating fiber (such as, for example, highly-nonlinear fiber (HNLF)) spliced to a second section of continuum-extending fiber (such as, for example, photonic crystal fiber (PCF)). The second section of fiber is selected to exhibit an anomalous dispersion value in the region of the short wavelength edge of the continuum generated by the first section of fiber. A femtosecond pulse laser source may be used to supply input pulses to the section of HNLF, and the section of PCF is spliced to the termination of the section of HNLF. A section of single mode fiber (SMF) is preferably inserted between the output of the laser source and the HNLF to compress the femtosecond pulses prior to entering the HNLF. It has been found that the hybrid combination of these two types of fibers allows for extension of the continuum on the short wavelength side—into the visible portion of the spectrum—by virtue of the first section of fiber acting as a “pump” source for the second section of fiber. | 2009-02-05 |
| 20090034563 | Tunable diode laser system with external resonator - A tunable diode laser system with external resonator in Littrow or Littman configuration has an optical lattice on which the light beam from a laser diode is diffracted, a support element to hold the lattice or to hold a mirror, which reflects the light diffracted by the lattice, and an actuator to change the position of the lattice or the mirror. The tunable diode laser system enables a reliable mode-hop-free tuning and furthermore is easy and economical to realize by having the support element include a carrier, on which the lattice or the mirror is arranged, and a base body, while the actuator acts on the carrier and rests against the base body. The carrier is connected to the base body via linkages, such that a linear deflection of the actuator is transformed into a rotation of the carrier in the plane of the light beam, while the center of rotation lies outside the base body. | 2009-02-05 |
| 20090034564 | Method and apparatus for detecting and avoiding multiple-pulse states in ultra-short-pulse laser - In a detection method for undesired double- or multiple-pulse states in an ultra-short-pulse laser system operated in the soliton regime and intended for generating femtosecond or picosecond pulses, comprising an amplifying laser medium for producing a laser emission, a laser resonator having at least one resonator mirror and a pump source, a first signal μ proportional to the pulse power P(t) or pulse energy averaged over the resonator cycle is measured for the laser emission. A second signal ν proportional to the square of the pulse power P(t), averaged over the resonator cycle, is measured for the laser emission, and the occurrence of a double- or multiple-pulse state is detected on the basis of a comparison of the measured signals μ and ν. | 2009-02-05 |
