Title: Optimizing a network topology to satisfy predicted growth
Inventor: Jay Perrett
IPC: H04L12/26
Filed: 2014-11-28
Abstract: Determining an optimum network topology for each of a plurality of demand scenarios, for example to evolve the topology of a network as demand increases over time. The method includes identifying, using an iterative process that involves generating and evolving a set of candidate network topologies, an optimum network topology for the highest demand scenario 304N. A network topology is then identified for the next-highest demand scenario using the same iterative process 304N-1, but this time the set of candidate network topologies is seeded to include the identified optimum network topology for the highest demand scenario. This process repeats for each other demand scenario so that each time the set of candidate network topologies is seeded with the determined optimum topology for the next-highest demand scenario. An alternative variation could begin by determining the optimum topology for the lowest demand scenario and iteratively seeding that topology as one candidate when determining the optimum topology for the next-higher demand scenario. An optimum topology is determined using a fitness value - a qualitative measure of how well that candidate topology meets specified constraints and service requirements (i.e. amount of data to be transmitted) of multiple services to be handled.

Title: A method of monitoring the usage of a boiler, a boiler and a boiler usage sensor
Inventor: JOHN SHERMER
IPC: F24H9/20
Filed: 2015-02-25
Abstract: A boiler 100 comprises a combustion chamber 102 in which a fuel is combusted. An electrically powered pressure control means, ideally a fan 120, controls pressure in the combustion chamber. An electrical current supplied to the fan is monitored, thereby monitoring usage of the boiler. Preferably a sensor 126, which may be a transformer sensor, Hall effect sensor or iron vane sensor, is used to detect electrical current supplied to the fan from an external power transmission source 127. The sensor ideally sends readings of electrical current supplied to the fan to a processing unit 130 via a wireless transceiver 132 and the processing unit determines whether the boiler is in an on-state or an off-state based on the readings. Monitoring boiler utilisation by sensing electrical current to the fan requires only simple retro-fitting of a boiler compared with monitoring utilisation by detecting a quantity of fuel received from a fuel source 106 using, for example, a gas usage sensor.
