Abstract: Disclosed are methods and devices for sensing the presence of aqueous droplets on digital microfluidic devices.

Abstract: A large area display having multiple sub-units arranged in rows and columns and a method of driving the multiple sub-units as a single display are provided. Each sub-unit has an associated pixel row driver and pixel column driver. The large area display may also include a chip select means that provides a separate chip select signal to the pixel row driver of each row of sub-units, so that in the row of sub-units for which the associated row driver has received the chip select signal, only the rows of pixels within a single row of sub-units are supplied data at any one time. Column data and delayed Gate Start Pulse signals are fed to the pixel column drivers in each column of sub-units such that the appropriate column data values are supplied to the associated pixel column drivers.

Abstract: A scooter (102) is provided comprising a plurality of components including at least support means for supporting at least part of a user thereon in use, scooter movement means associated with said support means for allowing the support means to move across a surface in use and handle means for allowing a user to hold onto the scooter in use. One or more of the components are provided with means to allow the component or a part of said component to move relative to another component or other part of said component between a first substantially erect condition and at least a second partially or substantially folded or collapsed condition.
