  • Patent number: 9640063
    Abstract: A sensor device used in remote monitoring of waste within a waste container includes a sensor arrangement for monitoring the waste and for generating a corresponding waste-indicative signal, a data processing arrangement for receiving the waste-indicative signal, a wireless interface coupled to the data processing arrangement for enabling the data processing device to emit wireless signals including information derived from the waste-indicative signal, and a power source for providing power to operate the sensor device. The sensor arrangement additionally includes a temperature sensor for measuring a temperature of at least the power source, and the data processing arrangement is operable to be switched from the second reduced-power mode to the first activated mode as a function of the temperature measured by the temperature sensor. This enables power saving and increased service life of the sensor, battery, and the waste container.

  • Publication number: 20170016180
    Abstract: The present invention relates to a method of producing steam at a digester plant of a chemical pulp mill. Black liquor is discharged from the digester at a first temperature and pressure. The black liquor is treated in a flash tank for generating flashed black liquor and flash steam at a second temperature and a second pressure, which are lower than the first temperature and pressure. The flashed black liquor is taken for further treatment to the evaporation plant. The flash steam is led to an indirect heat exchange contact with clean liquid in the reboiler for boiling the liquid and for generating steam. The steam is led from the reboiler into a fan or compressor for increasing the steam pressure to a third pressure, which is higher than the second pressure and for adjusting the pressure of the steam in the flash tank. Steam at a third pressure is used for pretreating comminuted cellulosic fiber material, such as chips, prior to cooking.

  • Publication number: 20160300297
    Abstract: A waste collection system (10) includes one or more waste containers (20) for receiving waste (50), a server system (100) for receiving one or more signals via a wireless communication network (70) from sensor arrangements (30, 40) included on the one or more waste containers (20) for sensing a waste status of the one or more containers (20). Beneficially, the server system (100) is operable from receiving the one or more signals to compute an optimal strategy for one or more waste collection vehicles (150) to collect waste from the one or more waste containers (20). The waste collection system (10) is capable of supporting a competitive bidding arrangement for implementing collection of waste (50) for the one or more waste containers (20).
