    摘要: The present embodiments generally relate to enabling participants in an online gathering with networked audio to use a cancelling auralizer at their respective locations to create a common acoustic space or set of acoustic spaces shared among subgroups of participants. For example, there are a set of network connected nodes, and the nodes can contain speakers and microphones, as well as participants and node mixing-processing blocks. The node mixing-processing blocks generate and manipulate signals for playback over the node loudspeakers and for distribution to and from the network. This processing can include cancellation of loudspeaker signals from the microphone signals and auralization of signals according to control parameters that are developed locally and from the network. A network block can contain network routing and processing functions, including auralization, synthesis, and cancellation of audio signals, synthesis and processing of control parameters, and audio signal and control parameter routing.

    摘要: An electromagnetic pump (100). The electromagnetic pump (100) comprises a conduit (101) comprising an inlet (103) and an outlet (105). A first magnetic field generating unit (109) is provided for generating a first magnetic field having a first component with a first direction in the conduit. A second magnetic field generating unit (111) is provided for generating a second magnetic field having a second component with a second direction in the conduit (101), the second direction being substantially opposite to the first direction. A piston member (113) is disposed within the conduit, the piston member (113) being moveable within the conduit (101) under the influence of the first and/or second magnetic fields to pump fluid received from the inlet (103) of the conduit (101) to the outlet (105) of the conduit (101).

    摘要: A method of separating acetylene from a gas mixture comprising acetylene is provided. The method involves the use of a hybrid porous material with an affinity for acetylene adsorption. The hybrid porous material comprises a three-dimensional structure of metal species (M) and first and second linker groups (L1 and L2), wherein the metal species (M) are linked together in a first and second direction by first linker groups (L1) and are linked together in a third direction by second linker groups (L2) to form the three-dimensional structure. The hybrid porous materials may have a high selectivity for acetylene and/or a high capacity for acetylene adsorption. The method may be particularly useful for the purification of ethylene gas contaminated with acetylene during an ethylene production/purification process. The method may be particularly useful for the large scale separation of acetylene from other gases such as ethylene and carbon dioxide, during an acetylene production/purification process.

    摘要: A method, a false start detection system, and a false start detection sensor for determining whether an athlete has performed a false start in an event. Force data is received representing the force exerted by at least one upper appendage of the athlete on a surface when in a starting position (S701). The force data is processed to determine an athlete start time (S702), and the athlete start time is compared to an event start time to determine whether a false start has occurred (S703).
