| 20100021883 | DETECTING, MEASURING AND CONTROLLING PARTICLES AND ELECTROMAGNETIC RADIATION - A method is provided for detecting, measuring or controlling particles and/or electromagnetic radiation, comprising providing a deformable material containing a deformable aperture defining a path for particles or radiation, adjusting the deformable aperture to a prescribed geometry and/or size by deforming the deformable material to change at least one of the parameters of the path defined by the deformable aperture, and causing the particle or radiation to be detected, measured or controlled to enter the deformable aperture. The method includes the step of monitoring the geometry and/or size of the deformable aperture and controlling the adjustment of the size of the deformable aperture in response to such monitoring. The required apparatus is easily fabricated from inexpensive materials. Furthermore the deformable aperture can be tuned to the appropriate geometry post fabrication, and the ability to adjust the aperture geometry renders it capable of discriminating a plurality of differently sized particles. | 01-28-2010 |

| 20110277545 | PRESSURE BALANCING DEVICE - A pressure balancing device for a transducer is provided. The pressure balancing device comprises: a pressure transmission device having a cross-sectional area and arranged, in use, to be exposed to a fluid; and a fluid chamber having a hollow shaft, the fluid chamber being arranged to be acted on by the pressure transmission device; wherein the cross-sectional area of the hollow shaft is less than the cross-sectional area of the pressure transmission device. | 11-17-2011 |

| 20080291842 | VIDEO QUALITY ASSESSMENT - The present invention relates to the problem of estimating the effect of packet transmission impairments, including packet loss, on the subjective quality of a video transmission where frames of data relating to the same video frame or field are permitted to span more than one packet. The invention provides a method of assessing quality of a video signal comprising a sequence of video frames received via a packet switched network using a parameter which is a weighted sum of two counters where the first counter is incremented in dependence of the total number of packets in frames determined to have been received with one or more lost packets and the second counter is incremented in dependence of the number of packets following the first lost packet in each frame and the lost packet itself. | 11-27-2008 |
