| 20080198292 | Lighting Device - The present invention relates to a lighting device wherein an in-coupled light flow is at least partly constrained within a light-guide plate ( | 08-21-2008 |
| 20080251434 | Manually Operable Water Purifying Device - The present invention relates to a manually operable device for purifying water, comprising a water container for receiving and holding an amount of non-purified water, comprising a bottom and side walls and adapted to receive a manually operable piston-type filter assembly, said filter assembly comprising filtering means for filtering said non-purified water, wherein said filter assembly is adapted to be manually forced towards the bottom of the said container, thereby allowing non-purified water to pass through the said filtering means thereby purifying the water. With the device according to the invention a low-cost water purifier is provided which can be used to provide an improved drinking water quality under primitive (outdoor) conditions, wherein no water pressure and/or electricity is present. | 10-16-2008 |
| 20090236960 | ELECTRIC LAMP AND INTERFERENCE FILM - An electric lamp has a light-transmitting lamp vessel ( | 09-24-2009 |
| 20090312905 | CONTROLLING SYSTEM FOR CONTROLLING AN AIR HANDLING SYSTEM - The invention relates to a controlling system for controlling an air handling system that is arranged to handle air in an enclosure such as a cabin of a vehicle. The controlling system comprises a first sensing unit, a second sensing unit, and a controller The first sensing unit is arranged to generate a first output signal based on a measurement of the 5 concentration of certain airborne pollutants at the upstream side of an air cleaning unit that is comprised in the air handling system. The second sensing unit is arranged to generate a second output signal based on a measurement of the concentration of certain airborne pollutants at the downstream side of the air cleaning unit. The first output signal and the second output signal are used for specific purposes in a decision-making process that can be | 12-17-2009 |

| 20100269600 | DEVICE FOR CHARACTERIZING A SIZE DISTRIBUTION OF ELECTRICALLY-CHARGED AIRBORNE PARTICLES IN AN AIR FLOW | 10-28-2010 |
| 20100282006 | DEVICE FOR CHARACTERIZING A SIZE DISTRIBUTION OF ELECTRICALLY-CHARGED AIRBORNE PARTICLES IN AN AIR FLOW - The invention relates to a device that can reliably characterize a size distribution of electrically-charged airborne particles in an air flow under both stationary conditions and transient conditions. The device comprises a particle charging unit, a first particle precipitation unit located downstream of the particle charging unit, a second particle precipitation unit located downstream of the first particle precipitation unit, and a data evaluation unit. The first particle precipitation unit is arranged to partially reduce the concentration of electrically-charged airborne particles having a size larger than a first particle size limit, and to generate a first output signal corresponding to the precipitation of electrically-charged airborne particles inside the first particle precipitation unit. The second particle precipitation unit is arranged to precipitate substantially all entering electrically-charged airborne particles, and to generate a second output signal corresponding to the precipitation of electrically-charged airborne particles inside the second particle precipitation unit. The data evaluation unit is arranged to calculate, based on the output signals of the particle precipitation units, a particle number concentration and an average diameter of airborne particles larger than the lower particle size limit. The device enables the simultaneous generation and recording of output signals, and consequently an immediate determination of the particle number concentration and the average particle diameter at any instant. | 11-11-2010 |
