A method (100) and a system (200) for predicting occupancy in a building premises. The method (100) includes receiving, by a processor (204), access control data of the building premises for a first time interval of a day and receiving, by the processor (204), presence sensor data of the building premises for the first time interval of the day. Further, the method is characterized by predicting, by the processor (204), an occupancy of the building premises for a second time interval of the day, based on at least one of: previously determined correlation between the access control data and an occupancy, and previously determined correlation between the presence sensor data and the occupancy.

Control of particles. A method of controlling at least one volumetric air flow among a plurality of fan filter units (1a - 1f) of a site comprising the plurality of units (1a - 1f), the method comprising the steps of: obtaining a first setting of the plurality of units (1a - 1f) of the site, the first setting of the plurality of fan filter units (1a - 1f) comprising a volumetric air flow rate through each fan filter unit (1a - 1f) and a type of each fan filter unit (1a - 1f); wherein the type of each fan filter unit (1a- 1f) is selected from a high-efficiency particulate air filter, an ultra-low penetration filter, obtaining a first configuration data set of the site, the first configuration data set comprising at least one floor plan of the site and a location of each fan filter unit (1a - 1f).

Die Erfindung betrifft ein Verfahren zur Überwachung eines Umgebungsparameters, insbesondere der Umgebungstemperatur, in einem Regallagersystem (RL) mit einer Vielzahl von Lagerfächern (LF) zur Einlagerung von Lagergut (LG). Es wird ein elektrischer Leckwellenleiter (SK) wie ein Schlitzkabel entlang der Lagerfächer verlegt. Es werden passive Funketiketten (TAG) mit jeweils einem Sensor (TS, HS) zur Erfassung eines jeweiligen Umgebungsparameters in den Lagerfächern zur Überwachung von eingelagertem Lagergut angebracht. Es wird ein HF-Energieversorgungssignal (EV) in den Leckwellenleiter eingespeist, wobei ein Teil der eingespeisten Signalleistung in Form elektromagnetischer Feldenergie zum Lagergut hin abgestrahlt wird. Ein Teil der vom Leckwellenleiter abgestrahlten elektromagnetischen Feldenergie wird von den passiven Funketiketten empfangen und zur elektrischen Eigenversorgung bereitgestellt, um ein wiederholtes Senden von Messwerten (U; T, H) zu einem erfassten Umgebungsparameter und/oder um ein sofortiges Senden einer Warnmeldung (AL) bei Überschreiten eines Grenzwertes an eine Gefahrenmeldestelle (Z) zu ermöglichen. Die Erfindung betrifft zudem eine Überwachungsanlage (BMA) und eine geeignete Verwendung.

The invention concerns a building air cooling system that comprises a thermoelectric heat pump (10) with a cold plate (11) and a hot plate (12), an indoor heat exchanger (3) for indoor air at the cold plate (11), a water duct (8) at the hot plate (12), an entry water conduit (50) at the water entry (30) of the water duct (8) and an exit water conduit (51) at the water exit (31) thereof. The entry water conduit (50) is configured flow-capably to connect to a plumbing system (40, 41) of a building. The exit water conduit (51) is configured to dispose of heat from the indoor heat exchanger (3) towards an outdoor environment. A flow-influence device (34, 35, 36, 37, 38) that is configured to influence the flow through the water duct (8) and to do so in the entry water conduit (50), the water duct (8) or the exit water conduit (51). The invention also concerns a method for installing suchlike building air cooling systems. The invention further concerns a room air cooling unit that comprises a thermoelectric heat pump (10) in between a heat-conductive foam (3) and a water duct (8), which are fixedly connected with respect to each other.

Apparatus and methods unobtrusively inspect an audio device (100). A signal generator (270) receives a pulse signal (272) from a controller (250). A low pass filter circuit (308, 310) creates a first signal (312) in response to the pulse signal (272). The first signal (312) has a fade-in and fade-out discharging phase (436, 446) corresponding to upper and lower voltages of the pulse signal (272), respectively. A transistor (316) creates a second signal (318) in response to the first signal (312). The second signal (318) is a modified version of the first signal (312) that includes a leveled-off portion in the fade-in charging phase (432, 442, 434, 444). The audio device (100) creates a third signal (320) in response to the second signal (318). The third signal (320) is a resulting version of the second signal (318) subjected to an audio element (210) of the audio device (100). The controller (250) determines whether the third signal (320) indicates a fault condition of the audio device (100) in response to subjecting the second signal (318) to the audio element (210) of the audio device (100).
