Title: Grid tied inverter having DC-DC current fed push-pull converter
Inventor: KNILL ALEXANDER CHARLES
IPC: H02J3/40
Filed: 2011-03-29
Abstract: A grid tied inverter connectable to an electricity grid comprises a DC-DC current fed converter 120, a transformer and an unfolding circuit 130. The unfolding circuit is connected to a mains electricity supply and the DC-DC converter is connected to a DC source, e.g. battery 110. The DC-DC converter generates a current waveform from the DC voltage source, where the current waveform is substantially synchronised to the electricity grid. The unfolding circuit is operable in a first mode to convert the current into a sinusoidal waveform having an instantaneous voltage suitable for injection into the grid, and in a second mode to convert AC electricity obtained from the grid into a fully rectified AC current. The DC-DC converter is further operable to convert the fully rectified AC current into a DC current for storage in the battery. The arrangement is suitable for connecting domestic producers of electricity to the grid.

Title: Improvements in or relating to optical beam detectors
Inventor: QUILLIAM SEAN
IPC: G08B29/18
Filed: 2013-04-24
Abstract: An arrangement is provided for reducing the occurrence of false alarms in optical beam detectors caused by ambient electromagnetic radiation. The arrangement comprises: a photosensitive device 10; an amplifier 20; a filter 30; a bias control 40; an output 50; and an ambient monitor 60. The photosensitive device 10 receives radiation including both background radiation and a reference modulated radiation, and provides a signal representative of such to the amplifier 20. The amplifier 20 amplifies and alters the phase of the signal by 180 degrees before providing it to the filter 30. The filter 30 removes a portion of the signal attributable to background radiation and further provides a signal to the photosensitive device 10 and the ambient monitor 60. The signal fed back to the photosensitive device 10 corresponds to the background radiation having a phase and amplitude equal and opposite to the background portion of the original signal. By feeding back this signal, cancellation of the ambient portion of the photosensitive device 10 is achieved. The filter 30 may be a band-stop or notch filter.

Title: An NFC reader transmits a frequency modulated signal and determines that a tag has been detected if a higher harmonic of the modulation frequency is detected
Inventor: JONES STEVE
IPC: H04W4/80
Filed: 2013-07-03
Abstract: A near field communications (NFC) reader for detecting the presence of an NFC tag is disclosed. The NFC reader has an antenna 22 tuned to a resonant frequency. The reader includes a first signal generator for generating a carrier signal (e.g. at 13.56 MHz) and a second signal generator 14 for applying a frequency modulation (of e.g. +/- 3.5 MHz) to the carrier signal at a modulation frequency (e.g. 100kHz). A driver 20 drives the antenna with the modulated signal. If an NFC tag is sufficiently close to the reader a periodic variation in the input impedance of the antenna is observed containing a strong frequency component at the fourth harmonic of the modulation frequency (see for example the K=0.2 trace in Fig. 4). The reader includes a detection system 26, 34, 36 to search for this fourth harmonic and when it is detected to indicate detection of a tag. In general, the invention could be applied to monitor any third or higher order harmonic. The detection system may include a bandpass filter 34 centred on a fourth harmonic of the modulation frequency (e.g. 400kHz), and a comparator 38.

Title: Performance metrics of a computer system
Inventor: BREW ANTHONY
IPC: G06F11/34
Filed: 2013-08-12
Abstract: Monitoring a large number of performance metrics, or key performance indicators (KPI), in a complex computer system can be overwhelming. It is desirable to call attention to only those metrics that indicate there may be abnormalities in system operation. Disclosed is a concept of identifying an inter-relationship between performance metrics of a computer system. The performance metric signals, which represent variations of performance metrics over time, are converted into quantised signals having a set of allowable discrete values. The quantized signals are compared to detect a correlation based on the timing of variations between them. An inter-relationship between the performance metrics may then be inferred, such that it may be necessary to monitor only one of them. Also disclosed is the use of correlation pair graphs (with nodes and edges) to graphically describe the relationship between a plurality of performance metrics.
