Title: Quantum key distribution system based on accumulation of geometric phase through transformation of a modal state
Inventor: WALKER STUART DOUGLAS
IPC: H04B10/548
Filed: 2007-07-25
Abstract: A method of encrypting data onto an electromagnetic beam, comprises providing an electromagnetic beam having a signal component having a modal state and a reference component; the signal component is susceptible to accumulation of a geometric phase. The beam is transmitted along a path over at least part of which the signal component accumulates a geometric phase by transformation of its modal state from a first modal state to a second modal state, from the second modal state to at least one further modal state, and then back to the first modal state. The geometric phase so accumulated is modulated with the data by modulating the modal state transformations. The first and second modal states may be the Hermite-Gaussian (HG) and Laguerre-Gaussian (LG) orbital-angular-momentum states respectively. In one embodiment Bob generates a beam including first and second orbital-angular-momentum components and Alice encrypts data on the beam by adding a data differential geometric phase between the orbital-angular momentum components.

Title: Methods and apparatus for monitoring airways
Inventor: WILKINSON MALCOLM HOWARD
IPC: A61B5/08
Filed: 2007-10-22
Abstract: Airway monitoring apparatus (30) includes a driver (6) for applying sound in the audible frequency range to the airway of a subject and a detector (7) for monitoring the response of the airway, e.g. by detecting transmitted sound signal components and/or reflected sound signal components. Variations in the detected sound signal, e.g. energy, due to attenuation of the signal, give an indication of the state of the airway, e.g. airway patency, and can be used to monitor sleep-disordered breathing events, such as apnea and hypopnea, and to provide a breathing event index, e.g. AHI. The apparatus may provide servo-control for a respiratory assist device, such as a positive airway pressure device, so as to provide an appropriate pressure level setting. It may allow for home use of such devices and for home titration. It may also assist in discriminating central and obstructive breathing events, and in providing a measure of airway resistance.

Title: Embedding a watermark in an audio signal and applying gain to it
Inventor: SLATER CHRISTOPHER
IPC: G10L19/018
Filed: 2008-09-01
Abstract: An apparatus for embedding a watermark in an audio signal, the apparatus comprising an input operable to receive the audio signal, a watermark adapting unit operable to receive the watermark from a watermark generating unit and adapt the profile of the frequency spectrum of the watermark to correspond to the profile of the frequency spectrum of the input audio signal and watermark embedding means operable to embed the adapted watermark in the audio signal. The watermark embedding means includes a watermark gain amplifier operable to apply a gain to the watermark before the watermark is embedded in the audio signal in accordance with a gain signal generated by a watermark gain value generator, wherein the watermark gain value generator is operable to adjust the gain applied to the watermark, the gain being determined in accordance with the presence of component of at least one peak having an amplitude above a threshold is described. Consequently, the invention identifies problematic parts of the audio signal which are likely to cause signal spreading outside of the masking limits of the human auditory system and thus increase audibility of the watermark and in response, adjust the watermark gain for the duration of the problematic parts.

Title: A process of manufacturing preformed hoops
Inventor: SCHMITZ CHRISTOPH
IPC: A41D20/00
Filed: 2008-11-18
Abstract: A process of manufacturing preformed hoops (fig 1) from one or two strips of material the preformed hoops may be worn as a headband, armband, tube top or belt for example, via a machine that positions the ends of one or more strips of material so that they can be connected together either permanently via adhesive or thermal bonding or releasably by releasable adhesive tapes or mechanical fasteners. Where two strips 1210 are to be joined together, the strips of material are placed on the surface of the rotating drum or turret of the machine (1300, fig 2A) parallel to each other with their longitudinal axis parallel to the centreline (1305, fig 2A) of the machine. Co-planer to the operating surface of the machine are four pivotally mounted supporting flipping plates 1310' that move from a rested position (1310, fig 2A) perpendicular to the centreline of the operating surface to a position (1310') parallel with the centreline lying on top of the ends 1212, 1218 of the material(s). The supporting plates temporarily fix themselves to the end of the strips e.g. vacuum suction before flipping back to their rested position. In the rested position the ends of the strips are positioned to allow them to be connected to each other to form a preformed hoop before being withdrawn from the equipment. Alternatively a piece of elasticated material may be fixed into the opening of the hoop (fig 2E) to allow the hoop to be adapted into a head band, adapted to form a cap, or adapted to form a disposable article such as a diaper (fig 3). A hoop may be made from a single strip of material using additional support plates to manipulate the strip of material prior to the ends being connected (figs 4A — E).

Title: Credit-based flow control where a credit allows sending only one packet at a time
Inventor: DORSCH RAINER
IPC: H04L12/56
Filed: 2008-12-05
Abstract: An apparatus and method is disclosed for transferring data packets synchronously in a credit controlled manner from a transmitter (10, fig. 1, not shown) to a receiver (20,fig. 1), wherein the receiver transfers a credit to the transmitter and the transmitter transfers said packets to the receiver in response to said credit showing available buffer space in a data buffer (26,fig.1) of the receiver. The data buffer (26) is configured to comprise a virtually unlimited buffer space offering infinite credits. The receiver creates a credit signal (CI1, C12, CI3, C14, DC12, DCI3), which shows, independent from a physical size of the data buffer (26), a virtual buffer space giving credit for just one further data packet to be received at a time from the transmitter, and transfers the credit signal to the transmitter, wherein the receiver component sends a credit (e.g. CI1) for a following packet as soon as it starts receiving a current packet, but can delay sending the credit for a certain time (e.g. DC12, DC13) if conditions in the data buffer demand a delay. The delayed credit forces the transmitter to insert a gap (e.g. FG1, FG2) between packets. The timing of the normal credit CI1 ensures that through put is not compromised.

Title: A nano imprint technique with increased flexibility with respect to alignment and feature shaping
Inventor: SEIDEL ROBERT
IPC: H01L21/768
Filed: 2008-12-11
Abstract: By forming metallization structures on the basis of an imprint technique, in which via openings and trenches may be commonly formed, a significant reduction of process complexity may be achieved due to the omission of at least one further alignment process as required in conventional process techniques. Furthermore, the flexibility and efficiency of imprint lithography may be increased by providing appropriately designed imprint molds in order to provide via openings and trenches exhibiting an increased fill capability, thereby also improving the performance of the finally obtained metallization structures with respect to reliability, resistance against electromigration and the like.

Title: FM demodulator with no requirement for limiter circuit
Inventor: PETTIGREW ARCHIBALD MCGILVRAY
IPC: H03D3/00
Filed: 2009-03-06
Abstract: The present invention relates to an FM demodulator incorporating a delay line quadrature detector. An Amplitude Locked Loop circuit (d) provides a carrier signal with no amplitude variation prior to performing a conversion from frequency modulation to phase modulation. A delay line (f) performs this conversion using a standard IF ceramic filter with a precise delay of 90 degrees at the un-modulated carrier frequency. The non-delayed carrier from the amplitude locked loop is multiplied by the delayed carrier using a four quadrant linear multiplier (i) to generate a demodulated audio output. The demodulator does not require hard pre-limiting of the input signal. The use of a delay line demodulator and a four quadrant multiplier provides a solution to the problem of noise spikes that arise during multipath reception of FM signals (also known as suppressed carried amplitude modulation events or SCAM-FM events).
