Abstract: A power supply module 100 is connected to a network client device 130. The power supply module is capable of powering said network client device, wherein the power supply module has a data memory 104 containing security information 126. The power supply module transfers the security information 126 from the data memory to the network client device. The security information may comprise a network key and/or a passphrase for generating a network key. The security information may comprise network parameters. The network may be a wireless network and may further be a secure wireless network that is at least partially in a restricted environment. The network may be a wireless gas sensor network. The security information may be used to encrypt and/or decrypt data sent over a wireless network. A commissioning device may write the security information into the data memory. The commissioning device may generate the security information. The security information may comprise a unique identifier for the network client device.

Abstract: Un sensor de gas para medir la concentración de un gas predeterminado comprende una fuente de luz (2) dispuesta para emitir pulsos de luz, un volumen de medición (10), un detector (4) dispuesto para recibir luz que ha pasado a través del volumen de medición (10), y un filtro adaptable (6) dispuesto entre la fuente de luz (2) y el detector (4) El sensor de gas tiene un estado de medición en el que pasa por lo menos una banda de longitud de onda que es absorbida por el gas y un estado de referencia en el que la banda de longitud de onda es atenuada en relación con el estado de medición. El filtro adaptable (6) está dispuesto para cambiar entre uno del estado de medición y el estado de referencia al otro por lo menos una vez durante cada pulso.

Abstract: A wireless sensor network comprises at least one sensor unit which comprises a sensor for sensing a parameter and at least one interrogating node. The interrogating node is arranged to transmit an interrogation message periodically to said sensor unit and to receive a reply message from said sensor unit. The sensor unit is arranged to transmit said reply message after a predetermined deliberate delay unless the sensor unit determines that an alarm condition has been met, in which case the sensor unit is arranged to transmit said reply message before the end of the deliberate delay.

Abstract: A gas sensor for measuring concentration of a predetermined gas comprises a light source(2)arranged to emit pulses of light, a measurement volume(10), a detector(4)arranged to receive light that has passed through the measurement volume(10), and an adaptable filter(6)disposed between the light source(2) and the detector(4).The gas sensor has a measurement state in which it passes at least one wavelength band which is absorbed by the gas and a reference state in which said wavelength band is attenuated relative to the measurement state. The adaptable filter(6) is arranged to change between one of said measurement state and said reference state to the other at least once during each pulse.

Abstract: In the technical field of gas sensors, gas concentration may be determined by passing light through a gas and measuring the relative attenuation of a reference wavelength band and a measurement wavelength band of the light. To obtain reliable measurements, it is necessary to wait for the light source to stabilize after it has been turned on due to drift and/or low-frequency noise present during warm-up of the light source. The present invention provides a gas sensor comprising a light source (2) arranged to emit pulses of light, and an adaptable filter (6) arranged to change between one of a measurement state and a reference state to the other at least once during each pulse. Switching at least once each pulse allows drift or low-frequency noise to be filtered out, allowing operation of the gas sensor during the light source warm-up period, thereby making the gas sensor more energy efficient.
