Surface-initiated Atom Transfer Radical Polymerisation (SI-ATRP) was employed for the synthesis of three different oil-compatible, hydrophobic polymer brushes based on alkyl methacrylates. This study presents polymerisation kinetics, chemical characterization by means of Fourier transform infrared spectroscopy (FTIR) and surface morphologies observed in atomic force microscopy (AFM). The lubrication properties of the anchored polymers were evaluated macroscopically by means of ball-on-disk methods and on the nanonewton scale by lateral force microscopy (AFM/LFM) and showed significant reduction in friction up to contact pressures as high as 460 MPa.

20090237335 | DISPLAY DEVICE ABLE TO OPERATE IN LOW POWER PARTIAL DISPLAY MODE - The display device includes a display cell including liquid crystals and a matrix of electrodes arranged in lines and columns in a closed cavity. The lines and columns define display cell pixels. The display device includes a control circuit for lines and columns for display of data on the display cell. In complete display mode, all lines and columns are addressed at several voltage levels by successive line-by-line multiplexing. In low power partial display mode, two groups of adjacent lines are joined so they are each controlled by a respective line control signal from the control circuit. The N lines and groups of lines are simultaneously addressed in active manner at two voltage levels. N line control signals include a series of N-bit binary line words that change every determined period of time, T, so 2 | 09-24-2009 |
20090237039 | METHOD OF CONTROLLING A DC-DC CONVERTOR IN DISCONTINUOUS MODE - A DC-DC converter includes an induction coil cooperating with two switches, which operate alternately, to supply output voltage of a determined level relative to input voltage. The converter control method includes, in each cycle, a first phase of first duration with first switch controlled to make it conductive, and to increase current in the induction coil, and a second phase with second switch controlled to be conductive and to decrease current in the induction coil during a second adjustable time period. Detection device detects, at the end of the second phase, sign of overvoltage across one terminal of the induction coil connected to the switches, and supplies a detection signal kept in a high or low state, depending upon sign of detected overvoltage. Timing device receives detection signal for adapting, in each successive cycle, the second duration of the second phase to cancel out current in the induction coil. | 09-24-2009 |
20090231217 | RADIATION DIAGRAM MEASURING SYSTEM FOR A TRANSMITTING ANTENNA - The measuring system includes a receiver including at least one fixed receiving antenna for picking up electromagnetic fields generated by a transmitting antenna belonging to an electronic device, and a positioning device on which a support element is placed. The positioning device includes mechanisms for driving the support element in rotation. The measuring system further includes a detection device for detecting position/orientation of the transmitting antenna, and a data processing station. A hollow spherical element houses the electronic device and is held on the positioning device by gravity on three points, one of which is formed by a drive member, and the two other points are formed using ball and socket joints. Several circular barcodes arranged on the external surface of the spherical element enable the system to determine the position/orientation of the spherical element using the digital camera. | 09-17-2009 |
