摘要： A photodetector sensor array device as usable for camera chips comprises upper and lower contact layers of n+ and p+ semiconductor material either side of a light absorbing region made of either one layer, or two oppositely doped layers, of semiconductor material. Insulating trenches of dielectric material extending through the layers to form the individual pixels. Respective contacts are connected to the upper and lower contact layers so that each pixel can be reverse biased or forward biased. In operation, the device is reset with a reverse bias, and then switched to forward bias for sensing. After switching, carriers generated in response to photon absorption accumulate in potential wells in the light absorbing region and so reduce the potential barriers to the contact layers, which causes current to start to flow between the contacts after a time delay which is inversely proportional to the incident light intensity.

摘要： A microfluidic device is provided for studying primary human airway cells cultured at the air-liquid interface defined in the device by a barrier between an apical and basolateral compartment provided by a porous support for growing a cell layer. Within the chip, a liquid flow channel is provided through the basolateral compartment. Primary measurement electrodes are arranged widely spaced apart in the basolateral compartment to cause a significant component of electrical current flowing between them to flow via the cell layer. Secondary measurement electrodes are also provided to make comparative measurements which are used to deduce parameters that are relevant for the equivalent circuit model use for analysing the data obtained from the primary measurement electrodes. The microfluidic device has a modular construction of substrate, spacer and sidewall piece, with the electrodes being formed on the substrate, and the substrate and spacer co-defining the flow channel.

摘要： An inspection method for optical components that can be implemented to conform to performance specification MIL-PRF-13830 in order to grade surface imperfections, in particular scratches and digs. A dark-field microscope obtains a digital image of the component, and this digital image is processed to determine scratch and dig numbers. For scratches, the number is obtained by dividing the total intensity of the scratch by the scratch length. For digs, the number is obtained by determining dig diameter or by dividing the dig's total intensity by its area. According to our extensive testing, this automated digital image processing approach appears to faithfully mimic the subjective impression that a scratch makes on an expert inspector who is applying the visibility test of MIL-PRF-13830.

摘要： A wireless receiver designed to conform to the standard IEEE 802.15.4. The receiver comprises an analog front-end and a digital decoder. The analog components of the front end include one or more amplifiers and an analog-to-digital converter (ADC). The digital decoder receives the output of the ADC and demodulates it in a demodulator which is driven at an a chip frequency by an internal or external clock. The demodulator comprises a sampler operable to sample the digital signal at a sampling frequency and a correlation unit operable to process a set of bits, referred to as a chip code, in the sampled digitised signal and output therefrom a set of correlation values. The set of correlation values is an indicator of likely mapping between the chip code that has been processed and a set of possible chip codes defined according to the standard. The demodulator further comprises a symbol selection unit and a frequency correction unit. The symbol selection unit has the function of deciding which symbol has been received based on an analysis of each set of correlation values. The frequency correction unit is operable to make adjustments to the chip frequency based on the correlation values output from the correlation unit, specifically to increase or decrease the chip frequency based on a measurement of whether the maximum correlation value among each set of correlation values occurs earlier or later than predicted. This scheme has the advantage that phase and frequency compensation is done after correlation avoiding the need for coherent demodulation while at the same time not requiring the stringent specifications of a conventional non-coherent demodulation scheme.

摘要： Metal nanovoids are grown on a stretchable plastic film. The fabrication proceeds by assembling the template of a single layer of close packed silica spheres on a conducting substrate. A conducting layer is then electrochemically grown on top to form a master. An elastomeric precursor is then coated on the master (e.g. by spinning) and is cured before removal. The resulting plastic film is then coated with a thin (e.g. 20nm) layer of noble metal (e.g. Au, Ag or Cu), to produce a flexible film. Applications for such tuneable structural colour would be coating of injection moulded artefacts, such as mobile phone covers, car bodies to form an iridescent skin, wall and fascia decorations, loudspeaker coatings, architectural tent coverings, and clothing.

摘要： An apparatus and method for rendering multiplanar reformatting (MPR) images of volume data to be displayed to a user. The apparatus may comprise a conventional personal computer system having a central processing unit (CPU) coupled to a system memory for storing the volume data and a graphics processing unit (GPU) having a GPU memory connected to the computer bus. The computer system CPU is configured to predict an MPR image which may be required for display at a future time and to identify blocks of voxels comprising the volume data which will be needed to render the predicted MPR image. The CPU is further operable to retrieve these blocks from the system memory and to queue them for transfer to the GPU memory. The transfer of blocks from the queue to the GPU memory is controlled by a scheduler such that at least some of the queued blocks are transferred to the GPU memory prior to the predicted MPR image becoming required for display. The GPU retrieves blocks from the GPU memory and renders corresponding image parts for assembly into the predicted MPR image should it become required for display.

摘要： A submersible electromagnetic (EM) field generator (5) for seafloor electromagnetic surveying comprising an AC to DC converter (18) operable to generate a DC output from an AC input and a switching module (19) operable to generate a waveform driving signal by selectively switching the DC output. The EM field generator also comprises an antenna (20) that is operable to generate an EM field in response to the waveform driving signal. This design approach of using a switched DC source allows square or rectangular wave EM signals to be generated which have sharp transition characteristics and which are substantially independent of the AC input characteristics.

摘要： A positioner (2) for moving a sample platform (6) relative to a base (4) is described. The positioner is driven by a piezoelectric arranged to expand and contract along a drive axis, the piezoelectric element has an input end coupled to the base and an output end coupled to first (14) and second (16) output levers extending away from the drive axis of the piezoelectric element in opposing directions. The output levers each have an inner arm arranged to be acted on by the piezoelectric element as it expands and an outer arm to which the sample platform is mounted via platform supports (26, 28). The output levers are mounted such that the piezoelectric element acts on the inner arms of the output levers to cause the outer arms to move in a plane containing the drive axis. This motion of the output levers is communicated via the platform supports to the sample platform, so moving it relative to the base along a direction parallel to the drive axis.
