Title: A load discriminator for an audio amplifier, the discriminator not using a test signal
Inventor: LESSO JOHN PAUL
IPC: H03F1/52
Filed: 2007-12-28
Abstract: A charge pump power supply 102 provides a supply voltage to an amplifier 16 driving a load 18, the nature of which (for example whether it is a line-out or headphones) is determined from the time taken for the charge pump output voltage to fall by a predefined amount or from the voltage drop during a predefined interval (figure 2) or from the rate of voltage droop. These parameters indicate the discharge rate of the charge pump reservoir capacitor 14 and thus provide an indication of the impedance of the load 18. Alternatively, the net charging rate of the capacitor 14 may be measured. A test signal generator is not required because the envelope detector 106 enables the decision circuit 104 to assess the impedance of the load by reference to the amplitude of the audio input signal. If the output load is determined to be a line output the signal amplitude may be raised, but if a headphone load is detected the signal amplitude may be reduced to protect the amplifier and the listener.

Title: Multimedia redistribution device transmitting digital television signal through available white space.
Inventor: O'REGAN FINBARR
IPC: H04H20/02
Filed: 2010-02-12
Abstract: Local distribution of multimedia content is performed by identifying available channels in the VHF/UHF spectrum in a local area, and transmitting the multimedia content using standard digital television signal as the modulation scheme. No adjustment to the digital television 20 receiver is necessary. The white space is analysed by means of a spectrum sensor 151 or a location unit 17. The spectrum sensor 151 can make use of time or frequency domain energy detection, wavelet spectrum estimation, covariance methods, matched filtering, spectral correlation, and higher order statistics. The location unit 17 determines the position of the device (for example through satellite or global positioning systems, GPS) and subsequently access geolocation databases 50 storing available stations. The conversion to a digital television format is operated via a transcoder 12 and a baseband processor 131. Examples of supported formats are: DVB-T, DVB-T2, DVB-H, DVB-SH, ATSC, ATSC-M/H, ISDB-T, 1seg, SBTVD, DMB-T, DMB-T/H, T-DMB.

Title: Cable network device with separate paths for upstream and downstream signals
Inventor: ARIESEN DIRK JAN
IPC: H04B3/00
Filed: 2011-05-05
Abstract: A cable network device 24 comprising an input 14 connected to a plurality of outputs 16 - 16", wherein the input is connected to each output by first and second electrical communication paths. Downstream signals from the input pass along the first electrical communication path and upstream signals from each output pass along the second electrical communication path.

The input is connected to a diplex filter 26 to separate electrical signals into high and low frequency bands and each output is connected to a second filter 30 to separate out upstream signals. This enables downstream signals to be subjected to different levels of attenuation to compensate for different levels of signal losses experienced by different users to ensure upstream and downstream signal quality is the same for each user.

Title: Archaeological dating technique
Inventor: WILSON MOIRA ANN
IPC: G01N25/56
Filed: 2010-05-10
Abstract: The present invention relates to a method of archaeological dating of ceramics materials. Dating methods are of paramount importance in the earth and environmental sciences, palaeontology, archaeology and art history. Laboratory based dating of any material depends on identifying and measuring a physicochemical property which changes in a predictable way with time, thus providing the material with an internal clock (as in radiometric dating). We disclose a modified method of determining the age of ceramic artefacts. Using our novel method, the measurement of mass gain kinetics together with total mass gain since manufacture (obtained by reheating) provides an accurate self-calibrating method of archaeological ceramic dating.
