Filed: 2016-04-28
Abstract: A direct current (DC) circuit breaker comprises a main circuit 302 and transient circuit 308 configured to carry respective main and transient-path currents between live and load terminals 304,306. When the main-path current through a first solid-state switch 312 exceeds a first threshold, a second solid-state switch 316 in the transient circuit is closed, after which the first switch is opened, diverting the main-path current to the transient circuit. A main contactor 310 is then opened when the main-path current falls below a second threshold, after which the second switch 316 is opened. Finally, when the transient-path current falls below the second threshold, an auxiliary contactor 314 in the transient circuit is opened. The transient circuit may further comprise a voltage clamping device 318 and a capacitor 320 connected in parallel with the second switch. The first and second switches may be, respectively, a low-voltage MOSFET and a high-voltage IGBT. The main and auxiliary contactors may be integrated as a single three-pole mechanical contactor (408, figure 4). A high-voltage semiconductor switch 322 may be coupled between the main circuit and ground, and be configured to remain open in normal operation and close upon detection of a high-impedance fault.

Title: Sound responsive device and method
Inventor: PAUL MOORHEAD
IPC: G10L25/78
Filed: 2017-06-28
Abstract: A sound operated device is controlled e.g. by voice recognition which can distinguish between real world sound and recorded sounds reproduced via a loudspeaker. The device includes at least one microphone which may be used to determine the origin of the sound and check if this is a known location of a loudspeaker. The device may also recognise characteristics of the sound indicating that it has been subjected to audio recording, audio broadcast and/or audio reproduction processes e.g. evidence of missing frequencies due to compression, rendering or encoding. A change in bit rate may also distinguish reproduced sounds. The device can therefore discriminate between live speech and recorded speech broadcast through a radio or television. The device may only respond when the speech is determined to be real live speech rather than pre-recorded. Reference templates and machine learning may be used to train the device.

Title: Methods in mass spectrometry using collision gas as ion source
Inventor: JOHANNES SCHWIETERS
IPC: H01J49/14
Filed: 2017-02-23
Abstract: A method of isotope ratio mass spectrometry for determining an isotope abundance and/or isotope ratio of sample ions. The sample ions are introduced into a collision cell along with a reaction gas to react with the sample ions to generate a chemical adduct ion species.
