Title: Detecting disease in retinal images
Inventor: FLEMING ALAN DUNCAN
IPC: A61B3/12
Filed: 2010-02-11
Abstract: A method of generating output data providing an indication of the presence or absence of disease from a retinal image of a patient involves receiving data from the image associated with the presence and abundance of three different types of eye lesion, such as microaneurysms, blot haemorrhages and exudates. These data are then combined to generate output data indicating the presence or absence of a disease, such as diabetic retinopathy, and these may represent confidence values associated with the detection of each lesion type in the image. These data can also be processed to generate a weight for each data value which influences how they are combined, such that the correspondence of the disease indicating output data withpredetermined classification data is maximised. Each retinal image may comprise two images corresponding one each to the left and right eyes of the patient.

Title: Timing alignment in a polar transmitter
Inventor: SHUTE NICHOLAS
IPC: H03F1/02
Filed: 2011-05-27
Abstract: During calibration, signals 302 and 304 of opposite phase are applied to the main and envelope paths so that the amplifier transits from saturation to linear operation twice per cycle. The amplitude of the amplifier output 306 is measured and the amplitudes of the peaks which occur during each transition are compared.

Title: Generating subcarrier signals for transmission in white space between adjacent television broadcast channels
Inventor: THIND SURINDER SINGH
IPC: H03B21/02
Filed: 2012-01-06
Abstract: Multiple RF subcarrier signals for transmission between two adjacent UHF broadcast channels are generated from a plurality of local oscillator LO signals using a plurality of mixers each arranged to mix one of the LO signals with one of a plurality of input signals. A TCXO 302 produces a reference frequency which is connected to a signal generating circuit 304a, which may comprise a VCO and PLL. Circuit 304a produces a first local oscillator signal LO1 which is mixed with a first input signal i1 in mixer 306. A second signal generating circuit comprises divider 304b and mixer 304c. The second signal generating circuit receives the reference frequency from the TCXO and receives the first local oscillator frequency LO1 and mixes these to produce a second local oscillator frequency LO2. Further stages may be added (fig.4). The generation of additional LO signals by means of counter and mixer combinations (e.g. divider 304b and a mixer 304c) reduces the cost of the circuit in comparison with the prior art (fig.2) which uses additional VCOs and PLLs. Variable gain amplifiers (516, fig.5) may provide independent amplification of the RF subcarrier signals before they are combined.
