Title: Schemes for controlling optical signals in optically functional waveguide structures
Inventor: NIPPA DAVID W
IPC: G02F1/065
Filed: 2005-03-31
Abstract: Methods of attenuating, delaying the phase, and otherwise controlling an optical signal propagating along a wave-guide are provided. According to one method, a variable optical attenuator structure is provided comprising a waveguide core (10), a cladding (20), an electrooptic polymer (30), and a set of control electrodes (40). The core (10), the cladding (20), and the electrooptic polymer (30) are configured such that an increase in the index of refraction of the polymer (30) causes a substantial portion of an optical signal propagating along the waveguide core (10) to couple into a relatively high index region (32) of the electrooptic polymer (30) above the waveguide core (10), so as to inhibit return of the coupled signal to the waveguide core (10). Another embodiment of the present invention introduces a phase delay in the coupled optical signal and permits return of the coupled signal to the waveguide core (10). An additional embodiment contemplates the use of a ridge waveguide structure to enable control of the optical signal.

Title: Telecommunications interface for providing unbalanced ringing
Inventor: HOY MICHAEL DAVEY
IPC: H04M3/02
Filed: 2008-05-23
Abstract: In order to provide unbalanced ringing when an exchange line card provides a balanced ringing output the interface provides a ringing detector in circuit with a customer pair. On detecting balanced ringing signals from the line card, the interface takes over the customer line pair and provides unbalanced ringing signals to the customer and monitors for customer answer. By inserting the interface in circuit at the main distribution frame of an exchange, legacy customer premises equipment which is unable to respond to balanced signalling can be provided with an appropriate ringing signal without the necessity to provide differing line cards at the exchange.

Title: Vacuum cleaner with ultraviolet light
Inventor: YOO DONG-HUN
IPC: A47L9/28
Filed: 2008-08-12
Abstract: A vacuum cleaner includes a cleaner body (10, fig 1) in which an ultraviolet UV irradiation unit 15 is mounted in a dust receptacle mounting unit 13. A dust receptacle 20 is detachably mounted in the dust receptacle mounting unit 13. The dust receptacle 20 has a UV transmission window 21 formed in a position facing the UV irradiation unit 15.

Title: Distinguishing maternal and foetal electrocardiograph signals using independent component analysis of waveforms from abdominal electrodes
Inventor: HERSH LAWRENCE T
IPC: A61B5/344
Filed: 2008-12-18
Abstract: Electrodes, from which a plurality of separate input waveforms are obtained over a predetermined period of time or epoch, are placed on the maternal abdomen. Independent component analysis is performed on the input waveforms to generate a plurality of ICA output waveforms. The output waveforms generated from maternal and foetal signal sources are determined and the waveforms that include maternal and foetal ECG signals are processed to generate physiological information, e.g. heart rate, for the mother and foetus respectively. ICA may be conducted on the input waveforms over sequential epochs to distinguish the maternal and foetal output waveforms independently for each epoch. Preferably, the maternal and foetal output waveforms are distinguished by comparison, with typical maternal and foetal profiles, of energy peaks from DFTs (discrete Fourier transforms), calculated for each of the output waveforms, the most closely corresponding being selected. The method may be used to determine a uterine activity signal. The foetal waveform may be determined by comparison with a template.

Title: Visualising a print on a surface
Inventor: HILLMAN A ROBERT
IPC: G06V40/13
Filed: 2009-03-24
Abstract: A surface having provided thereon a print, e.g. fingerprint, palm print, is contacted with a fluid, prefereably acidic, containing a monomer, e.g. aniline, pyrrole, thiophene. An electrical current is passed between the surface and the fluid to deposit polymer on the surface (i.e. electropolymerization of the monomer) at locations contacted by the fluid (e.g. between the ridges of a fingerprint). An electric potential can then be applied to the surface to visualise the print using electrochromic properties of the deposited polymer.
