Patent number: 11197965Abstract: The system allows optimizing the dispensing of aerosol medicaments. In particular the system allows the administration of an exogenous pulmonary surfactant to very young patients (e.g. preterm neonates). A catheter (101) conveys atomized surfactant directly to the retropharyngeal region in order to increase efficiency of the medicament administration without being invasive: this is particularly important for very young patients, such as pre-term born neonates suffering from neonatal Respiratory Distress Syndrome (nRDS). The catheter is made of biocompatible flexible material (e.g. plastic material). It is possible to couple the catheter with a rigid scaffolding (e.g. metallic) to increase stiffness of the device and to improve easiness of positioning operations. The delivery of the atomized medicament is done by means of an air blasting technique.Type: GrantFiled: October 16, 2014Date of Patent: December 14, 2021Assignee: CHIESI FARMACEUTICI S.p.A.Inventors: Raffaele Dellaca, Ilaria Milesi, Mario Di Cecio, Roger Fane Sewell, Donal Joseph Taylor

Patent number: 8742368Abstract: A photometric device for investigating a sample, comprises an array of radiation sources that are spaced apart from one another, and which are operable to generate radiation that differs from that generated by the other radiation sources in the array. The device includes a lens arrangement for focusing the radiation at a region of space where a sample may be located for example by means of a sample holder, and at least one detector for receiving radiation from the region of space. Preferably, a number of detectors are employed that are spaced apart from one another, and especially about an axis of the device, so that one radiation detector can detect radiation transmitted by the sample and the other detectors can detect radiation scattered by it. The radiation sources may be time division multiplexed so that in each time slot the detectors receive radiation originating from each radiation source.Type: GrantFiled: February 2, 2009Date of Patent: June 3, 2014Assignee: Cambridge Consultants LimitedInventors: Robert Jones, Roger Fane Sewell, Paul D. Ryder, Matthew J. Hayes, Edwin C. Carter

Patent number: 7917766Abstract: The invention comprises an encoder for encoding a stegotext and a decoder for decoding the encoded stegotext, the stegotext being generated by modulating the log power spectrogram of a covertext signal with at least one key, the or each key having been added or subtracted in the log domain to the covertext power spectrogram in accordance with the data of the watermark code with which the stegotext was generated, and the modulated power spectrogram having been returned into the original domain of the covertext. The decoder carries out Fast Fourier Transformation and rectangular polar conversion of the stegotext signal so as to transform the stegotext signal into the log power spectrogram domain; subtracts in the log power domain positive and negative multiples of the key or keys from blocks of the log power spectrogram and evaluates the probability of the results of such subtractions representing an unmodified block of covertext in accordance with a predetermined statistical model.Type: GrantFiled: October 9, 2007Date of Patent: March 29, 2011Assignee: Activated Content CorporationInventors: Roger Fane Sewell, Mark St. John Owen, Stephen John Barlow, Simon Paul Long

Patent number: 7278574Abstract: A barcode reader and processing circuitry are disclosed for identifying a position of a cylinder rod, for example, along a path of movement. The barcode is marked on a surface of the rod and constitutes a series of markings extending along a portion of the length of the rod. The markings represent encoded information based on numbers calculated with a random number generator, and are grouped into subsets, each of which corresponds to a particular rod position. A portion of the rod including a subset of barcode markings is exposed to light emitted from the reader. Light reflected off the barcode is sensed with an array of photosensors provided in the reader. The photosensors generate electrical signals, and using Bayesian probability, a likely subset of markings is determined corresponding to the received electrical signals. Once identified, the markings subset is associated with a location corresponding to the position of the rod.Type: GrantFiled: February 26, 2007Date of Patent: October 9, 2007Assignee: Caterpillar Inc.Inventors: Roger Fane Sewell, Robert Jones
