The invention relates to a method for preparing metal nanoparticle-modified boron-doped diamond the method comprising generating a strong oxidising agent by acid treating a front surface of the boron-doped diamond prior to deposition of the metal nanoparticles onto the front surface of the boron-doped diamond. The metal nanoparticle-modified boron-doped diamond resulting from the acid wash has a front surface which is oxygen terminated. The metal nanoparticle-modified boron-doped diamond may be used in electrodes as an oxygen sensor, the electrode may be made by preparing a boron-doped diamond column; insulating the column so that only a front surface of the column is exposed; polishing the front surface of the column; acid-treating the front surface of the column; and depositing metal nanoparticles onto the front surface of the column.

A scroll wheel assembly includes a rotatable member. Encoded rotation of the rotating member causes scrolling of an image on a display screen along an axis. An actuator is located within the rotational member. Pressure on different parts of the actuator causes scrolling of the image in opposing directions along a second axis. Pressure upon additional parts of the actuator can provide additional screen functions. Functions and commands caused by manipulation of the rotatable member or actuator may also be programmable.

A broadcast data receiver (BDR) is provided and a method of using the BDR for the production of a pseudo stable reference control for the reliable generation of composite video signals. The BDR receives video, audio and/or auxiliary data from a broadcaster can stored a part of all of the data in storage means, typically in the form of a hard disk drive. When the BDR is deriving video data from the hard disk due to the BDR being disconnected from the signal feed from the broadcaster, the BDR uses a pseudo stable reference produced by deriving one or more values from stable frequency information embedded in incoming data. The pseudo stable reference is used to control the frequency of a VCXO in the BDR, thereby allowing accurate color sub-carrier frequency generation for the generation of a final video output. The one or more values can be average stable reference control values extracted from the incoming data or the one or more values can be derived from locking the frequency of the VCXO to an off air incoming data stream.

The present invention provides thickened fabrics and reinforcements for use as a spacer or reinforcement for a matrix system. The fabric includes in a first embodiment a woven fabric comprising weft and warp yarns containing glass fibers. A portion of the weft yarns are undulated, resulting in an increased thickness for the fabric. The fabric is coated with a polymeric resin or bonding agent, for substantially binding the weft yarns in the undulated condition. This invention also includes methods for making such fabric by increasing the thickness of a woven or non-woven material by such methods as applying tension during weaving operations, or using unbalanced yarns.

Food packaging comprising a container containing food and having an upper opening allowing access to the food, and first removable closure means for the upper opening, an end wall comprising at least one perforated zone having holes that can prevent food from passing through while allowing the passage of steam, the packaging comprising second removable closure means that can close off the holes, the second closure means being accessible from the outside. The packaging also comprises a solid skirt, projecting out from the container surrounding the perforated zone, and having at least one opening, the skirt promoting the passage of steam towards the perforated zone and towards the container.
