Title: Drive circuit for a machine having a dual stator winding
Inventor: LEWIS ERIC ANTHONY
IPC: H02P27/12
Filed: 2006-12-18
Abstract: The drive circuit of the invention includes an ac supply network 4 and first and second network rectifier/inverters 10 and 12 (which can be active or passive) that are connected to the ac network in parallel. A first PWM rectifier/inverter 200 is connected to the first network rectifier/inverter 10 through a first dc link 204. A second PWM rectifier/inverter 202 is connected to the second network rectifier/inverter 12 through a second dc link 206. A first two-layer stator winding 208 having a plurality of individual stator coils is connected to the first PWM rectifier/inverter 200 and a second two-layer stator winding 210 having a plurality of individual stator coils is connected to the second PWM rectifier/inverter 202. The stator coils of the first stator winding 208 and the stator coils of the second stator winding 210 are interconnected such that, in use, the vector sum of voltages across the stator coils in the first stator winding is substantially equal to the vector sum of voltages across the stator coils in the second stator winding. This has the advantageous effect of reducing the PWM frequency current harmonics flowing in the first and second stator windings 208 and 210.

Title: Medium for growing human embryonic stem cells
Inventor: XU CHUNHUI
IPC: C12N5/00
Filed: 2005-07-13
Abstract: This disclosure provides an improved system for deriving culturing human pluripotent stem cells. Traditionally, pluripotent stem cells are cultured on a layer of mouse embryonic fibroblast feeder cells to prevent them from differentiating. In the system described here, the role of feeder cells is replaced by defined components added to the culture environment that support rapid proliferation without differentiation. The medium contains an isotonic buffer, a blend of essential nutrients such as protein and lipids, and an effective growth factor or combination of factors that promote proliferation while inhibiting differentiation. Culturing human embryonic stem cells in fresh medium on an extracellular matrix according to this invention causes the cells to expand surprisingly rapidly, while retaining the ability to differentiate into cells representing all three embryonic germ layers. This new culture system allows for bulk proliferation of pPS cells for commercial production of important products for use in drug screening and human therapy.

Title: Overcoming space charge effects in ion cyclotron resonance mass spectrometers
Inventor: BAYKUT GOEKHAN
IPC: G06Q10/06
Filed: 2007-12-17
Abstract: A method of operating an FT-ICR mass spectrometer, in which the ions are trapped axially using potentials at a pattern of electrode elements 28. During their flight near these electrode patterns 28, the ions experience either a repulsive inhomogeneous alternating radiofrequency field induced pseudopotential, or a repulsive inhomogeneous motion induced pseudo-potential. According to the invention an additional electrostatic ion-attracting field is superimposed onto the repulsing alternating electric field. By adjustment of the voltage for the ion-attracting field, the cyclotron frequency shift of the ions caused by the space charge is compensated, and the mass determination process is greatly improved. At a particular strength of the additional electrostatic ion-attracting field, the ion cyclotron frequency of all ions becomes independent of the number of ions inside the ICR trap. At this adjustment, the operation of the ICR mass spectrometer becomes optimal for all types of routine applications.

Title: Transmitter phase correction during intervals of low signal power
Inventor: KODNER LIONID
IPC: H04L27/36
Filed: 2008-10-31
Abstract: An RF transmitter (100) for transmitting a QAM signal includes a baseband signal generator (101) for producing a baseband modulation signal, and an analyzer (126) for analyzing the baseband signal to detect low signal periods when a parameter (such as power) which is a function of the amplitude of the signal is not greater than a threshold. The transmitter also includes a phase error detector (132), a phase shifter (133) and a phase shift controller (131). The phase shifter (133) may change the phase of the baseband signal or of a signal derived from it or mixed with it. The phase shift controller receives a signal from the phase error detector. The phase shift controller also receives from the analyzer an indication of the low signal periods and applies a control signal to the phase shifter so that a change in phase, required as a result of a detected phase error, is applied only at times corresponding to low signal (low power) periods of the baseband signal. Spectral spread ('splatter') and inter-channel interference are thus reduced. The invention may be applied to transmitters, such as TETRA transmitters, using linearity control loops, Cartesian loops, a feed-forward loop or a pre-distortion loop.

Title: Semiconductor light source
Inventor: GROOM KRISTIAN MICHAEL
IPC: H01L33/00
Filed: 2009-06-10
Abstract: A method of fabricating a semiconductor light source structure for super-luminscent diodes (SLDs) or semiconductor optical amplifiers (SOAs), comprising providing a GaAs substrate; forming an A1xGa1-xAs, a lower cladding layer above the substrate; forming a GaAs separate confinement heterostructure as an active region above the lower cladding layer; and forming an upper cladding layer above the active region, the upper cladding layer comprising an elongate stripe of A1xGa1-xAs bounded on either side by an InGaP current-blocking layer, the elongate stripe defining an index-guided optical waveguide. The stripe is formed such that at least one free end of the stripe is spaced apart from an edge of the substrate and a portion of the lower cladding layer, active region, current blocking layer and upper cladding layer extend beyond the stripe thereby to provide an unpumped and laterally unguided window region. The advantages of this are reduced reflectivity at the stripe/window boundary, this advantage is increased further by tapering the edge of the stripe. The stripe may be formed via etching or cleaving.

Title: Agile illumination for biometric authentication
Inventor: JELINEK JAN
IPC: G06K9/00
Filed: 2008-04-01
Abstract: An agile illumination apparatus for use in biometric authentication is disclosed. A controlled spot flash strobe forms and focuses a narrow illuminating beam so as to cover an area of interest for a biometric authentication of a target with a spot of light of constant size regardless of a distance of the target from the controlled spot flash strobe. A positioner can then be utilized to steer the narrow illuminating beam to a target in a monitored space. The spot size is kept constant and its irradiance distribution is kept uniform in order to deliver a constant amount of energy to the target irrespective of the distance, wherein the controlled spot flash strobe automatically reduces its power as the target moves closer to the controlled spot flash strobe in order to maintain a constant exposure value and provide for enhanced biometric authentication of the target.
