Patent number: 9706289Abstract: Loudspeaker systems and assemblies are provided in which mid-frequency producing drivers are provided on opposing sides of a high frequency source comprising a linear high-frequency source connected to a waveguide. Crossover circuitry is provided such that the acoustic output from the mid-frequency drivers overlaps with that of the high-frequency source over an intermediate frequency range associated with acoustic interference between the mid-frequency producing drivers. In some embodiments, the mid-frequency producing drivers are recessed behind the output of the waveguide, and optionally angled outwardly from the waveguide, in order decrease the distance therebetween.Type: GrantFiled: August 31, 2015Date of Patent: July 11, 2017Assignee: ADAMSON SYSTEMS ENGINEERING INC.Inventors: Alan Brock Adamson, Ben Cabot, Douglas Campbell

Patent number: 9282402Abstract: A control and distribution system provides electrical power distribution, audio signal distribution, and control signal distribution to one or more audio components, such as a powered loudspeaker element or a signal conditioning device such as a rack-mounted amplifier. Embodiments allow for the monitoring and/or control of parameters and/or components at or near the endpoint of the system. These parameters or components include low-level parameters associated with the external audio devices, as opposed to merely higher level parameters of the system. The control and distribution system may include an uninterrupted power source for providing power in an online or offline mode to selected components of the external audio devices. In some embodiments, online backup power is provided to low-power components without providing power to amplifiers within the external audio devices.Type: GrantFiled: March 14, 2013Date of Patent: March 8, 2016Assignee: ADAMSON SYSTEMS ENGINEERING INC.Inventors: Alan Brock Adamson, Ben Cabot

Patent number: 8590666Abstract: Disclosed herein is a rigging component and method for connecting an array element in an array. The rigging component includes an elongate housing connectable to an array element; a connection link disposed within, and slidably extendable from, one end of the housing; a conduit extending into the housing from its opposite end, the conduit dimensioned to receive another connection link extending from an adjacent rigging component; and at least one latching device associated with the conduit for releasably retaining the other connection link within the conduit. Further disclosed is a system for connecting an array element in an array. The system comprises at least one rigging component having a connection link extendable to be locked at a single fixed distance and at least one rigging component having a connection link extendable to be locked at one of a plurality of fixed distances.Type: GrantFiled: October 13, 2010Date of Patent: November 26, 2013Assignee: Adamson Systems Engineering Inc.Inventors: Alan Brock Adamson, Ben Cabot, Ewan James McDonald

Patent number: 8421535Abstract: Provided are apparatuses and methods for reducing nonlinear distortions in Class D amplifiers by dynamically changing first and second threshold voltages in a pulse width modulator. A Class D amplifier apparatus is disclosed, comprising a pulse width modulator whose operation relies on a first and second threshold value, and a threshold controller which varies the thresholds in response to internal signals in the amplifier. Further, a method of processing Class D amplifier internal signals is disclosed, comprising steps involving measuring internal signals in a Class D amplifier and varying threshold signals in response to those measurements within the amplifier.Type: GrantFiled: August 8, 2011Date of Patent: April 16, 2013Assignee: Adamson Systems Engineering Inc.Inventor: Stefan Roman Hlibowicki
