  • Patent number: 9033026
    Abstract: A plate heat exchanger (10) of the double plate type having a plurality of stacked plate elements, each comprising a first plate (1) and a second plate (9). At least the first plate (1) is provided with a surface pattern with a plurality of dimples (5) defining a first distance to a plate plane (8), and a plurality of canal parts (6) defining a second, smaller, distance to the plate plane (8). The first plate (1) and the second plate (9) are joined in such a manner that the protruding areas (5, 6) in combination form flow paths (11) being fluidly connected to rim portions (3) of the plates (1, 9). The heat exchanger (10) provides efficient leakage detection via the flow paths (11) while ensuring a good thermal contact between heat exchanging fluids through the plates (1, 9) via flat portions (7) between the protruding parts (5, 6).

  • Publication number: 20150003470
    Abstract: There is provided a compression method for TDM frames transported over a packet network. The method is based on mapping of allocated TDM slots but not all un-allocated slots into a transport structure, which thereby reduces the needed amount of data transported over packets and hence reduces the required packet rate and packet capacity during transport of the TDM frame. The mapping is further arranged to allow dynamic changes of packet rate and packet capacity, thus the mapping is performed such that a working size of the transport TDM frame is allowed to increase or decrease over time. Further, mechanisms to lower experienced delay for low-rate signals are provided.

  • Publication number: 20130162584
    Abstract: An electronic device with a touch screen display that includes capacitive sensing to determine the point of contact between the display and an input device. The device also includes a graphics circuit for rendering images on the touch screen display. The graphics circuit may be inactivated when not in use. The inactive mode provides a variety of advantages, such as a lower power drain on the power source. The device is further configured to sense the approach of an input device in proximity to the display. The device is configured to start activating the graphics circuit upon sensing the approach of the input device prior to contact with the display. The timing of the activation improves responsiveness of the electronic device.
