Title: Vacuum cleaner with filter cleaning system
Inventor: GOGEL NATHAN A
IPC: A47L9/20
Filed: 2006-07-11
Abstract: A floor cleaning apparatus 10 includes a dirt collection vessel 30 and a suction generator 32 carried on the housing 12. The dirt collection vessel 30 includes a dirty air inlet 44, a dirt collection chamber and a clean air outlet 48. A filter 52 is received in the dirt collection vessel 30. The filter 52 includes multiple sections 60. Each section 60 provides a discrete airflow pathway. In addition, the floor cleaning apparatus 10 includes a flow control valve assembly 70 including a clean air inlet 50. The flow control valve assembly 70 is selectively displaceable between two positions. In the first position dirty air is serially moved by the suction generator 32 through the dirty air inlet 44, the dirt collection chamber, the filter 52 and the clean air outlet 48 so that dirt is collected in the dirt collection chamber. In the second position clean air is moved by the suction generator 32 through the clean air inlet 50, a selected one of the sections 60 of the filter, back through the other sections 60 of the filter and then through the clean air outlet 48. In this way dirt is cleaned from the selected section 60 of the filter 52. Additionally means to rotate the filter 52 may be provided, so that each filter section 60 may be cleaned in turn. The application also describes the use of vibration to remove dirt from the filter 52. This is achieved by rotating the filter against a "clicker" (ref 130, fig 8).

Title: Anonymous authentication in a distributed or peer-to-peer network
Inventor: IRVINE DAVID
IPC: G06F21/41
Filed: 2006-12-01
Abstract: This present invention relates to an authentication system for users requiring to be allowed access to resources stored on a distributed or peer-to-peer system. Information supplied during the authentication process by the user is extremely difficult to be compromised because these details are not stored on a central server and are not transmitted over the network during the process. In combination with this, information about the location of nodes is not stored together on the network. This obviates the opportunity for an unauthorised user to use that information to identify the location of resources in order to gain unauthorised access. It is the intention of this present invention to preserve the anonymity of the user and to provide a mechanism for secure access to private storage of data and preferably other resources on a distributed file system.

Title: Distortion compensation
Inventor: KASHIWA TAKUO
IPC: H03F1/32
Filed: 2005-06-28
Abstract: A distortion compensating circuit capable of compensating for the nonlinearity of an amplifier having such characteristics that the gain is compressed as an input power increases to cause phase lag. An inductor (112) is connected in series with a diode (105) in the distortion compensating circuit (100). Since the resistive component of the diode (105) decreases as the input power increases, impedance effect of the inductor (112) connected in series with the diode (105) appears, and such characteristics that the impedance of the distortion compensating circuit (100) becomes inductive to cause phase lead are attained. Since the resistive component of the diode (105) decreases as the input power increases, loss is reduced and gain increasing characteristics are attained.

Title: Means for achieving low order detonation of a device filled with a metal oxyanion / bidentate fuel ligand complex by means of a low power diode laser
Inventor: AHMAD S RAFI
IPC: F42B3/113
Filed: 2007-04-28
Abstract: A means is provided for initiating a low order detonation (e.g. detonation velocity below 3500 m/s) in a detonator tube filled with salts of a Metal Oxyanion / Bidentate fuel ligand complex (MOS-Bid) such as Nickel Hydrazine Nitrate (NiHN) by means of a low power diode laser operating at the near-infrared (NIR) wavelength of 808 nm. The diode laser wavelength chosen matches the absorption band of Nickel Hydrazine Nitrate. The laser may have a power output of up to 1.5W and may be delivered down a fibre optic cable to cause detonation. The time to detonation following a prompt laser pulse can be adjusted by varying the laser power or the diameter of the fibre optic cable. The arrangement is particularly suited for application to a guided weapon where a NIR diode laser proximity sensor is used such that at the appropriate stand-off distance from the target, light from the proximity sensing laser can easily be directed down a fibre optic cable to a NiHN detector in order to detonate the warhead.

Patent GB-2457499-A (GB)
Title: A gravity activated motor
Inventor: BRINTON BRIAN JOHN
IPC: F03G3/00
Filed: 2008-02-16
Abstract: This machine operates solely by the force of gravity acting on it. It consists of a set of weight wheels which, when acted upon by gravity, cause a driven wheel to rotate. The rotation of the driven wheel is brought about by the continuous varying in length of the lever arms, centres of weight wheels to centre of the driven wheel. A particular feature of this motor is that the variations in length of the lever arms occur even though the weight wheels are travelling a circular path at all times. The beneficial consequence of this method of working is that there is no reduction of the energy output of the motor caused by repeated variations in the lines of travel of the weight wheels, while wear of the moving parts and vibration of the motor are both reduced.

Title: A System, Method and Control Apparatus of Driving a Fan and DC Motor Unit
Inventor: ETO JUN
IPC: H02P7/06
Filed: 2008-03-28
Abstract: A fan system includes a fan 3 driven a DC motor 2 and a fan housing. A fan control apparatus 1 includes a control unit configured to control a rotation speed of the fan so as to periodically change around a specific rotation speed based on data corresponding to a specific rotation speed. Preferably the fan is operated at a predetermined speed or voltage and the control unit fluctuates the actual speed or voltage around the predetermined speed/voltage. Thus the fluctuation of speed is in a sinusoidal waveform with the predetermined speed/voltage acting as the amplitude centre. Vibration levels of the fan housing are preferably reduced by the fluctuation of the drive voltage as it disperses the vibration frequencies over a wider frequency range.
