Abstract:
The present application relates to an apparatus for purifying and/or humidifying air, and a related method for purifying and/or humidifying air. The apparatus comprises a rotary filter (1), a fan (9, 10) for passing air through the rotary filter (1), and a reservoir (4, 5), and wherein the rotation speed of the rotary filter (1) and the settings of the fan (9, 10) depend on the ambient relative humidity and ambient gas pollutant concentration. The apparatus combines the feature of chemisorption with the use of a rotary filter (1), thereby providing an apparatus which is able to purify air and/or regulate the ambient humidity based on humidity levels and levels of a target gas pollutant in the air. The invention removes the need for a pump for liquid transport, removes the need for frequent and expensive filter changes by the user, and instead only requires the user to periodically refresh the filtration solution in the reservoir (4, 5).

Abstract:
In various embodiments, an air purification system (100, 300, 400) may include a first air filter (316, 416) that targets at least a first type of pollutant. In various embodiments, air that passes through the first air filter may be unobstructed by other air filters. In various embodiments, a second air filter (316, 416) may target at least a second type of pollutant that is different than the first type of pollutant. In various embodiments, air that passes through the second air filter may also be unobstructed by other air filters. In various embodiments, a controller (102, 302) may be configured to selectively move the first and/or second air filters to expose one or both of the first and second air filters to one or more air streams, e.g., based on user input and/or on one or more signals from one or more pollutant sensors (106, 306).
Abstract:
An air treatment system (100) is provided that comprises an air purifier (110) arranged to treat a first parameter of ambient air; a controller (130) arranged to control operation of the air purifier (110); and a sensor (120) arranged to detect a value indicative of the first parameter, and to output sensor data indicative of the value to the controller. The controller (130) is arranged to determine whether the sensor (120) and the air purifier (110) are in a same air space by controlling the air purifier (110) to operate in a test mode and analyzing sensor data from the sensor (120) received during the test mode. If the sensor (120) and the air purifier (110) are determined to be in the same air space, the controller (130) is arranged to control the air purifier (110) to operate in a mode based on sensor data from the sensor (120).
Abstract:
An apparatus and method is disclosed for preventing a viewer from switching from a channel when an advertisement is being displayed on the channel. The apparatus and method comprises an advertisement controller in a video playback device that (1) prevents a viewer of a direct (non-recorded) broadcast from switching channels when an advertisement is displayed, and (2) prevents a viewer of a recorded program from fast forwarding the recorded program in order to skip past advertisements that were recorded with the program. A viewer may either watch the advertisements or pay a fee in order to be able to change channels or fast forward when the advertisements are being displayed.
Abstract:
The present invention relates to a roasting method of roasting partially roasted coffee beans; the roasting method comprises the steps of: obtaining a roast level of the partially roasted coffee beans; determining a roasting profile for roasting based on at least the roast level of the partially roasted coffee beans prior to roasting; and roasting the partially roasted coffee beans according to the determined roasting profile. The present invention also proposes a method of making coffee, a roasting device and a coffee machine providing a segmented roasting solution.
Abstract:
The present invention relates to a method of processing frozen food, the method comprising the steps of: applying a first thermal power to the frozen food; detecting a water phase change of the frozen food; and applying a second thermal power to the frozen food when the water phase change of the frozen food is detected. A device based on said method is also proposed. The method detects the water phase in food as the indicator of the thawing process, and can detect thawing progress through the change of this indicator. With the proposed method or device, the thawing progress of the frozen food can be controlled intelligently and more precisely.
Abstract:
An air purification apparatus (100) is disclosed that comprises a flow channel (110) extending between an inlet (111) and an outlet (113); a pollutant removal structure (120) and an air displacement apparatus (130) in the flow channel; a branched sensor channel (140) including: a first branch (142) extending between an ambient air port (141) and a further outlet (143) in the flow channel between the inlet and the air displacement apparatus; and a second branch (144) extending between the ambient air port and a further inlet (145) in the flow channel between the air displacement apparatus and the outlet, the first branch and second branch sharing a branch section; at least one sensor (150) in the shared branch section; a valve arrangement (161, 163) in the branched sensor channel adapted to exclusively disconnect the first branch from the flow channel in a first configuration and exclusively disconnect the second branch from the flow channel in a second configuration; and a controller (170) adapted to control the valve arrangement.
Abstract:
The invention describes a modular fluid sensing system comprising a fluid sensing terminal (150) and removable fluid channel units (101, 102, 103). The fluid channel units (101, 102, 103) comprise or can be combined with fluid treatment units as filters, sensors and seals. The fluid channel units (101, 102, 103) can be combined in accordance with the present needs of the user of the fluid sensing system. The invention therefore enables a reconfigurable channel system with reconfigurable measurement and treatment options within a fluid sensing system.
