Title: Projection display using wire grid polarisation beamsplitter with compensator
Inventor: SILVERSTEIN BARRY D
IPC: G02B27/28
Filed: 2003-04-22
Abstract: A display apparatus (10) including a light source (15) for forming a beam of light. A pre-polarizer (45, 230) polarizes the beam of light to provide a polarized beam of light. A wire grid polarization beamsplitter (50, 240) receives the polarized beam of light and transmits the polarized beam of light which has a first polarization, and reflects the polarized beam of light which has a second polarization. A reflective spatial light modulator (55, 210) selectively modulates the polarized beam of light that has a first polarization to encode image data thereon in order to form a modulated beam and reflects the modulated beam back to the wire grid polarization beamsplitter (50, 240). A compensator (260) is located between the wire grid polarization beamsplitter (50, 240) and the reflective spatial light modulator (55, 210) for conditioning oblique and skew rays of the modulated beam. The wire grid polarization beamsplitter (50, 240) reflects the compensated modulated beam and the wire gird polarization beamsplitter (50, 240) is rotated in plane to optimize the contrast. A polarization analyzer (60, 270) removes residual light of the opposite polarization state from the compensated modulated beam (360). Image-forming optics (70, 285) form an image from the compensated modulated beam.

Title: A Cartesian loop amplifier in which the input signal level is reduced when distortion is detected
Inventor: BEN-AYUN MOSHE
IPC: H03F1/34
Filed: 2003-06-17
Abstract: When an isolator is not provided between a power amplifier 126 and an antenna 128, reflected power can increase amplifier distortion. Because an isolator is bulky, narrowband and expensive, it is preferred to use instead an isolator eliminator 106 which attenuates the input baseband signals when excessive adjacent channel power is detected in the Cartesian loop error signals. Attenuation is increased in steps, allowing time for settling of the loop, until the ratio of the adjacent channel and on-channel signal amplitudes falls below a threshold. The on-channel and adjacent channel amplitude signals are produced respectively by low-pass 138,142 and bandpass filters 140,144 coupled to root-mean-square detectors 146,148.

Filed: 2004-01-19
Abstract: A keypad comprises a light-emitting element (110), and a light-detecting element (114) adapted to produce an output voltage dependent on the detected light level, and a processing means adapted to interpret the output of the light-detecting element, including a filter between the light-detecting element and the processing means adapted to block the DC element of the output voltage at least during measurement thereof by the processing means. It will usually be preferred that the keypad includes a plurality of keys, each key including an associated light-detecting element and (usually), each key including an associated light-emitting element. The outputs of the plurality of light-detecting elements are preferably multiplexed in a multiplexing element (120) and fed to a single processing means. In this case, the filter preferably acts on the output signal between the multiplexing element (120) and the processing means. The filter can include a capacitive element (126) in series connection to block the DC signal. A resistive element (124) in parallel connection is also preferred. The filter preferably includes a reset line which, when activated, zeros the output thereof. A transistor (128) arranged so as to ground the output of the filter when the reset line is activated is suited to this task. The processing means can then activate the reset line prior to taking a measurement. A suitable light-detecting element is a phototransistor (114), and a suitable light-emitting element is a photodiode (110).

Title: Measuring the rate of permeation of gases through a sample
Inventor: NOERENBERG HOLGER
IPC: G01N15/08
Filed: 2004-02-09
Abstract: An apparatus for measuring the rate of permeation of gases through a sample comprises a filling chamber 3, an evacuation pump 6, a transfer arm 8, a xyz-stage 9, a mass spectrometer 10 and a gas container 26. The gas container 26 has a window at one end, where the film to be tested 29 is clamped, and further comprises a valve 31 and a bellows arrangement 25 27. The bellows arrangement enables the volume of the gas to change as temperature of gas in the chamber is varied thus minimising temperature induced changes in pressure. The gas container 26 is first filled with a saturated vapour or gas in the filling chamber 3. It is then transferred to an investigation chamber and is positioned to face the mass spectrometer. The mass spectrometer measures partial pressure of the saturated vapour or gas in the chamber, the rate of decay in partial pressure being proportionate to the permeation of gases through the film. The precise position of the sample relative to the mass spectrometer may then be changed using the XYZ-stage and position resolved measurement of permeation achieved.
