Title: Tag arbitration management method and system
Inventor: TURNER CHRISTOPHER GORDON GERV
IPC: G06K7/00
Filed: 2004-02-06
Abstract: The invention describes an arbitration management method and system for use in identifying RFID transponders or tags which each transmit a response signal to a reader within a respective waiting period the maximum duration of which can be adjusted. The maximum duration is determined by a random number transmitted to a counter (20) along a number of data lines (1,2,4,8), at least one of the data lines (4,8) being provided with logic gates (40,30) which block or permit data line signals reaching the binary inputs (26,25) of the counter to control the maximum length of the waiting period. The claimed advantage is that fewer additional logic gates are required compared with a non adjustable wait time device. This results in decreased chip complexity, simplified operation and reduced power consumption which translates into longer read ranges.

Title: Mist injector for gas treatment
Inventor: DAVIS HOWARD PAUL
IPC: F23J15/00
Filed: 2004-07-16
Abstract: A device and a method for producing a fine liquid mist and injecting the said mist into a gas stream to capture and remove very fine particulate pollutants. A gas stream is passed into a droplet generator (20) into which liquid is sprayed and atomised into a mist which captures particulates present in the gas stream. A droplet separator (30) separates the liquid/particulate mixture and results in a gas stream with a reduced concentration of particulates. Advantageously the main application is the removal of fine particulates from vehicle exhaust streams. Optionally a degassing stage (90) is provided for the removal of residual gases and vapours. The preferred liquid to form the mist is water.

Title: Product packaging with printed circuit and means for preventing a short circuit
Inventor: STONE KATE JESSIE
IPC: B31B50/88
Filed: 2007-10-18
Abstract: A packaging for a product comprises a plurality of conductive tracks 14 for forming a printed circuit on a sheet of material with a physical barrier, such as a hole 24, for impeding fluid flow between adjacent conductive tracks.

Patent GB-2458711-A (GB)
Title: Replacing bad blocks in a main partition of memory with blocks from a secondary partition which can be used as a swap partition
IPC: G06F11/07
Filed: 2008-05-30
Abstract: Bad block management is implemented for the main partition 310 in a memory having a main 310 and a secondary partition 320. The secondary partition provides spare blocks to replace bad blocks in the main partition, but can also be used for other purposes. In particular, the secondary partition can be used as a swap partition for implementing paging of the main partition, especially writable demand paging. As bad blocks are replaced, the size of the secondary partition decreases. The secondary partition may be resized dynamically or when the computing device in which the memory is provided is next restarted. Paging of the main partition may be disabled once the number of blocks remaining in the secondary partition is less than a threshold. This invention negates the need to provide redundant blocks (240 fig 2) although a dedicated pool of spare blocks may be provided to facilitate temporary replacement of bad blocks in the main partition during use when the secondary partition is to be resized upon restarting the computing device.
