| 20080304379 | Writing and Reading of Data in Probe-Based Data Storage Devices - Methods and apparatus are provided for controlling writing and reading of data in an array of A storage fields of a probe-based data storage device in which data is written to and read from the array of storage fields by a corresponding array of probes. One method uses the concept of sub-arrays to provide variable-rate read/write operation. Input data blocks are received for writing to the A-field array, each input data block being writable in A/k | 12-11-2008 |
| 20090089645 | DATA STORAGE SYSTEMS - Method and apparatus for decoding data in a data storage system. In operation, a detector generates an output bit stream in dependence on a data block received from a storage subsystem of the data storage system. A post processor connected to the detector generates a first error corrected bit stream in dependence on the output bit stream and the data block. An error correction decoder connected to the post processor generates a second error corrected bit stream in dependence on the first error corrected bit stream and also generates a checksum in dependence of the second error corrected bit stream. A feedback path supplies from the error correction decoder to the post processor pinning data indicative of locations of correct bits in the second error corrected bit stream in the event that the checksum is indicative of errors in the second error corrected bit stream and the second error corrected bit stream comprises at least one correct interleave. The post processor regenerates the first error corrected bit stream in dependence on the pinning data received from the error correction decoder. | 04-02-2009 |

| 20080279558 | METHOD & APPARATUS FOR CLEARING AN OPTICAL CHANNEL - A method and apparatus for clearing an optical channel for transmitting data through free space between a first and second location includes a light beam, wherein the light beam has a spatially and/or time-dependent modulated intensity profile, and is substantially collimated so that the intensity profile is conserved over a specified distance of operation. The light beam includes a cross-sectional profile having regions of low and high intensity, portions of which are provided for the transmission of an optical data signal. A light source wavelength and intensity are selected for types of obscurant particles having optical properties whereby the radiation pressure acts on the particles, and the particles may then be either attracted into or repelled from portions of the spatially modulated optical beam, leaving certain portions of the optical channel beam absent of obscurant particles, thereby enabling transmission of optical data through the cleared optical channel with low attenuation. | 11-13-2008 |
| 20110133104 | OPTICAL MANIPULATION OF MICRO-PARTICLES - A method for manipulating one or more particles comprising exposing the particle(s) to a beam of radiation that is able to lift and or impart an acceleration to the particle(s) to cause it to move in a curved trajectory. | 06-09-2011 |

| 20080274529 | Photoporation Of Cells - An opening is formed in a cell using laser radiation. A Bessel beam is formed using the laser radiation and the Bessel beam is directed onto the cell to form an opening. The guiding of material towards the opening may be involved using optical trapping/manipulation. The material may change cellular function or analyse cell behaviour. Both pulsed laser radiation and continuous wave radiation may be formed using the same laser. | 11-06-2008 |

| 20100014078 | RAMAN SPECTROSCOPY - A micro-fluidic system comprising means for optically trapping a particle and a Raman excitation source for causing Raman scatter from the particle whilst it is in the optical trap. | 01-21-2010 |
| 20100032555 | Acousto-Optic Sorting - A method for sorting particles in a fluid. The method involves generating an optical landscape using an acousto-optic device. Preferably, the optical landscape is arranged to sort particles based on size or refractive index or shape. | 02-11-2010 |
| 20100047761 | CAPILLARY TRANSPORT - A method for sorting particles, in particular cells A and B. The method uses a single channel with only one input and only one output. A particle mix A and B in a fluid is introduced into the channel and particles within the channel are sorted. | 02-25-2010 |
| 20100328657 | Enhanced Spectroscopic Techniques Using Spatial Beam Shaping - A Raman spectrometer comprising means for illuminating a sample with a shaped laser beam and a detector that is operable to detect light that is reflected from or transmitted through a sample. Preferably, the shaped laser beam has a dark spot at its centre. | 12-30-2010 |
