  • Publication number: 20160106838
    Abstract: A composite implant comprising an injectable matrix material which is flowable and settable, and at least one reinforcing element for integration with the injectable matrix material, the at least one reinforcing element adding sufficient strength to the injectable matrix material such that when the composite implant is disposed in a cavity in a bone, the composite implant supports the bone. A method for treating a bone comprising: selecting at least one reinforcing element to be combined with an injectable matrix material to form a composite implant capable of supporting the bone; positioning the at least one reinforcing element in a cavity in the bone; flowing the injectable matrix material into the cavity wherein the injectable matrix material interfaces with the at least one reinforcing element; and transforming the injectable matrix material from a flowable state to a nonflowable state to establish a static structure that supports the adjacent bone.

  • Patent number: 8704498
    Abstract: A voltage source converter (10) for use in three-phase high voltage DC power transmission and reactive power compensation. The voltage source converter (10) comprises three converter limbs (12,14,16) connected in a bridge circuit arrangement wherein each of first and second converter limbs (12,14) includes a multilevel converter (18) and a third converter limb (16) includes a capacitor (20) on each side of a series AC phase connection (22). The multilevel converters (18) are controllable to synthesize waveforms at series AC phase connections (24,26) of the first and second converter limbs (12,14).

  • Publication number: 20140098575
    Abstract: A converter, for use in high voltage direct and alternating current power transmission comprises a primary charge transfer converter. The charge transfer converter includes first and second primary terminals for connection to one or more electrical networks. The primary charge transfer converter also includes a plurality of charge transfer elements and a plurality of primary switching elements which are connected in a cascade circuit between the first and second primary terminals. Each charge transfer element includes at least one resonant circuit. The primary switching elements are operable to selectively cause charging and discharging of each resonant circuit to transfer charge between the charge transfer elements and thereby create a voltage difference between the first and second primary terminals.
