| 20120112165 | Optical Device - An improved optoelectronic device is described, which employs optically responsive nanoparticles and utilises a non-radiative energy transfer mechanism. The nanoparticles are disposed on the sidewalls of one or more cavities, which extend from the surface of the device through the electronic structure and penetrate the energy transfer region. The nanoparticles are located in close spatial proximity to an energy transfer region, whereby energy is transferred non-radiatively to or from the electronic structure through non-contact dipole-dipole interaction. According to the mode of operation, the device can absorb light energy received from the device surface via the cavity and then transfer this non-radiatively or can transfer energy non-radiatively and then emit light energy towards the surface of the device via the cavity. As such, the deice finds application in light emitting devices, photovoltaic (solar) cells, displays, photodetectors, lasers and single photon devices. | 05-10-2012 |

The method for classifying a shockwave generated and directed towards a stone in an extracorporeal shockwave lithotripsy treatment comprises receiving an acoustic signal at a passive unfocused acoustic sensor, determining whether at least one characteristic of the received acoustic emissions exceeds a respective pre-determined threshold value, and classifying the shockwave as effective or ineffective in dependence upon said determination.

| 20100241193 | Signal Processing In Devices, For Use With A Deficient Signal-Responsive Body Part - A cochlear implant provides electrical pulses to neurons and is configured to convert the excitation signal into a sparsified signal for electrically stimulating the neurons, thereby reducing the redundancy of the stimuli applied to the neurons. A signal analyser is configured to perform dimension reduction or factorisation of said excitation signal in the time domain or in the frequency domain followed by a sparse transform, the resulting relatively clean output signal providing the input to an inverse transformation step to create the sparsified signal. The dimension reduction or factorisation can be performed by principal component analysis (PCA), and the sparse transform can be performed by independent component analysis (ICA). | 09-23-2010 |

| 20100067000 | Raman spectroscopy - It has been discovered that specially structured metallic films containing voids can deliver a hugely enhanced surface enhanced Raman spectroscopy (SERS) effect. By selecting a particular size and geometry for the voids, metallic films can be provided which have an enhanced photon-to-plasmon conversion efficiency for incident radiation of a predetermined wavelength. Controllable surface-enhanced absorption and emission characteristics may thus be provided, which are useful for SERS and potentially also other optical spectrometry and filtering applications. With such a large Raman signal, the invention enables fast, compact and inexpensive Raman spectrometers to be provided opening up many new application possibilities. | 03-18-2010 |

| 20080204747 | Multiwavelength Optical Sensors - An optical sensor comprises at least two planar Bragg gratings defined on a single substrate and arranged to receive light from a light source, each grating having a wavelength filtering response that varies with an effective modal index experienced by light propagating in the Bragg grating and a Bragg wavelength different to those of the other gratings, and at least one sample window overlying one or more of the gratings that can receive a sample of fluid that affects the effective modal index and response of the grating, the gratings filtering the light and outputting the filtered light for spectral analysis, from which the refractive index and related properties of the fluid can be determined. One or more of the gratings can be a reference grating used to compensate for temperature and other disturbances to the sensors. Gratings may have individual sample windows for testing separate fluid samples, or may share a common window so that a single fluid can be tested using several gratings. | 08-28-2008 |
