  • Patent number: 11067684
    Abstract: Embodiments provide a data receiver with a unit for receiving sub-data packets configured to receive at least two sub-data packets from a data transmitter, and to combine the at least two sub-data packets to obtain a data packet that is transmitted split into the at least two sub-data packets by the data transmitter, wherein each of the at least two sub-data packets is shorter than the data packet, a unit for receiving sub-data packets configured to receive the at least two sub-data packets on at least two different carrier frequencies a unit for determining a phase difference configured to determine a phase difference between the at least two sub-data packets that is caused by the at least two different carrier frequencies and the path delay, and a unit for determining a distance difference configured to determine a distance difference between the data receiver and the data transmitter based on the determined phase difference between the at least two sub-data packets.

  • Patent number: 9709351
    Abstract: A heat exchanger (5) includes a housing (31), which contains a tube (32) and has a jacket (33), which surrounds the tube (32) while forming a ring channel (34). A primary inlet (35) and a primary outlet (36) are fluidically connected with one another via a primary path (37) carrying a primary medium through the ring channel (34) and via a bypass path (38) carrying the primary medium through the tube (32). A control (39) controls the flow of the primary medium through the primary path (37) and through the bypass path (38). At least two secondary inlets (42) and two secondary outlets (43) are fluidically connected with one another via at least two secondary paths (44) for carrying at least one secondary medium. The primary path (37) is coupled with the secondary paths (44) in a heat-transferring manner and such that the media are separated from one another.

  • Patent number: 9140146
    Abstract: A steam generator (1) is provided for a Rankine cycle, especially for a waste heat recovery device (37) of an internal combustion engine (36), and preferably in a motor vehicle. The steam generator includes: a heat exchanger channel (2), in which a heat exchanger (3) is arranged, and a bypass channel (4) for bypassing the heat exchanger channel (2). A heating fluid can flow through the heat exchanger channel (2) and bypass channel (4) during the operation of the steam generator (1). A medium to be evaporated can flow through the heat exchanger (3) during operation of the steam generator (1). A compact structural shape with high energy efficiency is achieved with the heat exchanger channel (2) enveloping the bypass channel (4).

  • Publication number: 20150020705
    Abstract: An apparatus (10) for releasing a fluid to the atmosphere comprises a housing (12) for the fluid. The housing can comprise a biodegradable polymer, or a polymer that has been adapted to biodegrade. The polymer can also comprise a component that is reflective to infrared radiation so as to prevent melting of the housing polymer during immersion in or whilst in proximity to flame. The apparatus further comprises a mechanism (30,32,42,50,56,58) for causing the fluid to be released to the atmosphere from the housing. The mechanism can be housed in a second housing (14) that is detachably mounted to the first housing to define a housing unit. Further, a restraint mechanism (34) can be provided for regulating when the fluid is to be released from the housing to the atmosphere. The restraint mechanism can be deactivated once a certain force of apparatus impact with a surface has been reached.
