Title: Post-production circuit performance adjustment by inducing a permanent change in the threshold voltages of transistors
Inventor: HOLD BETINA
IPC: G11C7/06
Filed: 2013-11-27
Abstract: The performance of a MOS circuit may be adjusted after manufacture by exposing transistors 26,28 within the circuit to voltages, currents, or temperatures that are of a magnitude or duration not experienced during normal operation of the circuit, to effect a persisting change in the threshold voltage of the transistors and hence an adjustment in the circuit speed. Multiplexers 24 may be used to apply programming voltages to the transistors in place of normal logic voltage signals. Programming voltages may be applied to the gates and drains of MOS transistors respectively to decrease and increase switching speed. Device matching in sense amplifiers for memories may be improved (figures 7 and 8), and the sense amplifier bias current may be varied (figure 6). The delay of a delay line comprising an inverter string may be adjusted (10 figure 1).

Title: Hydrokinetic system
Inventor: TREVARTHEN JEREMY GRAEME CHARLES
IPC: F03B17/06
Filed: 2014-01-02
Abstract: A hydropower turbine comprises a horizontal axis rotor 12 and a deflector 100 on each side of the rotor 12 to direct water flow to undershot and overtopping flow paths, both of which drive rotation of the rotor. Overtopping water is collected in a funnel-shaped reservoir (103, figure 2c) which directs the water to the back of the rotor in a breastshot arrangement to assist rotation of the rotor. The system uses floating pontoons 1 which are bridged by the rotor 12 and deflectors 100. A deadweight anchor system for mooring the system and connecting electrical cables is also described. Deflectors on both sides of the rotor mean that the system can be used in reversing (tidal) flow.

Title: Locating electrical faults in a circuit
Inventor: HANDY PETER JAMES
IPC: G01R31/11
Filed: 2014-09-02
Abstract: Method and apparatus for locating a defect 161 in a transmission line 160. A switch 190 is opened in the electrical loop causing an open circuit 162, 163 or discontinuity at the fault. A signal is transmitted into the transmission wire by a reflectometry system and is reflected at the fault, the reflected pulse being received to determine fault position, for example by using the predetermined signal propagation speed. Opening the switch 190 disconnects power source 170 so that any arcing collapses, resulting in an open circuit when the arc quenches. The method is thus suitable for high voltage supply with wires extending to perhaps kilometres in length, such as power supply circuits in aircraft, ships, factories or hospitals. A series RC snubber 194 may be present to ensure arc quenching and signals may be injected into the line before the switch is opened.
