Abstract

The invention relates to a feeding device (1) for introducing a piece of linen (12) to be ironed into an ironing unit by means of suction, the feeding device (1) being provided with a suction shaft (3) into which the piece of linen (12) can be sucked and a top suction portion (4) which is provided for sucking the piece of linen (12) into the suction shaft (3). The feeding device (1) comprises a blocking clamp (6) which is provided to secure the piece of linen (12) in a clamping position, and which is arranged in the feeding device (1) in such a way that there is located after the clamping of the piece of linen (12) a portion of this piece of linen (12) above this blocking clamp (6) that can be sucked by the top suction portion (4) into the suction shaft (3). The invention further relates to an ironing device, comprising an ironing unit for ironing a piece of linen (12) and a feeding unit (1) for feeding the piece of linen (12) to be ironed into the ironing unit.

Claims

1. A system for automatically adjusting a lighting atmosphere based on presence detection, the system comprising

at least one sensor for gathering information associated with a presence level of people in a supervised area, said gathered information including the number of people in the supervised area and the number of people passing through the supervised area, and

a processing unit for determining the presence level of people in the supervised area based on the gathered information and for adjusting the lighting atmosphere based on the determined presence level by controlling the dynamics level and interactivity level of the lighting atmosphere depending on the determined presence level,

wherein the processing unit is configured:

to compare the determined presence level with a threshold and to adjust the lighting atmosphere, if the determined presence level is above the threshold, and

to control said dynamics level and said interactivity level of the lighting atmosphere such that one or more dynamic effects of the lighting atmosphere are either disabled or visibly altered, if the determined presence level is above the threshold.

2. The system of claim 1, wherein the at least one sensor is selected from the group consisting of:

a grid of infra-red presence sensors;

a floor embedded presence sensor; and

a computer vision camera.

3. The system of claim 1, wherein the processing unit is further configured to receive the gathered information from the at least one sensor wirelessly.

4. The system of claim 1, wherein the processing unit is further adapted for adjusting the lighting atmosphere based on the determined presence level by controlling the dynamics level of the lighting atmosphere directly depending on the determined presence level, wherein the level of dynamics is lowered if the determined presence level raises.

5. The system of claim 4, wherein the processing unit is further adapted for setting the level of dynamics to the lowest level, if the determined presence level is above a threshold.

6. An atmosphere creation system comprising

a lighting system comprising at least one light unit and being adapted to automatically generate a lighting atmosphere with the at least one light unit,

a presence sensor electronically connected to a processing unit, said presence sensor capable of detecting the number of people in a supervised area and the number of people passing through said supervised area;

said processing unit operable to determine a presence level in said supervised area;

a system for automatically adjusting the generated lighting atmosphere based on said present level by controlling the lighting system including control of a dynamics level and an interactivity level of said lighting system such that one or more dynamic effects of said lighting system and said interactivity level are disabled when said presence level is above a predetermined threshold.

7. Method for automatically adjusting a lighting atmosphere based on presence detection, comprising

gathering information on a presence level of people in a supervised area by detecting the number of people in said supervised area and detecting the number of people passing through said supervised area,

determining the presence level of people on the supervised area based on the gathered information, and

adjusting the lighting atmosphere based on the determined presence level by controlling the dynamics level and the interactivity level of the lighting atmosphere depending on the determined presence level;

disabling said interactivity level of said lighting atmosphere when said determined presence level is determined to be above a predetermined threshold, said predetermined threshold representative of a high level of occupation of people in said supervised area.
