  • Patent number: 9967673
    Abstract: An acoustic transducer comprises one or more electromagnetic motors that drive one or more sets of multiple diaphragms to provide acoustically efficient loudspeaker systems having dimensions that allow use in applications that would be difficult or impossible with traditional transducers. The diaphragms may be driven directly, inertially or fluidically. If diaphragms are driven by rods that pass through holes in the diaphragms, noise may be generated by air that leaks through the pass-through holes. This noise may be reduced or eliminated by measures that reduce or eliminate the air leakage.

  • Patent number: 9462388
    Abstract: An acoustic transducer includes a housing, a plurality of diaphragms suspended from the housing and separated into one or more groups, and one or more motors combined with the housing that operate in response to an electrical signal. The diaphragms of each group are driven by a respective motor to which all the diaphragms in the group are coupled and at least one motor has an indirect coupling with no direct mechanical connection to the diaphragms driven thereby. One or more electromagnetic motors that drive one or more sets of multiple diaphragms to provide acoustically efficient loudspeaker systems having dimensions that allow use in applications that would be difficult or impossible with traditional transducers.

  • Patent number: 7854477
    Abstract: A seat back support mechanism supports the back of a seat in a motor vehicle. One component of the mechanism (15) is effectively connected to the seat of the motor vehicle and another component (32) is connected to the back (44) of the motor vehicle optionally by means of a recliner mechanism. The support mechanism comprises a connection between the components. The connection comprises two pivot links (27,33). One pivot link (33) is of arcuate form with a central ā€œVā€ notch so that when the back of the seat is subjected to a predetermined force, the back of the seat is permitted about a pivot axis (30) while the arcuate pivot link (33) is deformed, thus absorbing energy.

  • Patent number: 7669894
    Abstract: An airbag system is disclosed comprising a gas generator and an airbag having at least two inflatable airbag regions. The airbag regions are attached to the gas generator by an interconnecting a T-shaped connecting piece having symmetrically opposed outlet stubs with differently sized outlet cross-sections for inflating the airbag regions. In order to neutralize the thrust of the system in case of accidental fire, several means for controlling the outlet cross-section on at least one of the outlet stubs are disclosed.
