Patent number: 8473844Abstract: A system for management and control of audio-related equipment. A link manager may be included in the system. The link manager may be configured to manage subscriptions to multiple other audio-related devices or control panel views. When the managed data variables change, the link manager module may notify other audio-related devices and/or control panel views of the change. In response to the notification, the other audio-related devices and/or control panels may subscribe to the audio-related device with the changed data variable, to request receipt of the updated data variable. In some examples, the link manager module may also be configured to lessen the subscription burden for a particular audio-related device.Type: GrantFiled: March 25, 2005Date of Patent: June 25, 2013Assignee: Harman International Industries, IncorporatedInventors: Richard Allen Kreifeldt, John Lee, William A. Plunkett, Timothy J. Shuttleworth, Andrew Stevenson, Bruce Vander Werf, Steve Hatch, Michael Douglas Hamling, Scott Gardner

Publication number: 20130061738Abstract: An incendiary machine (10) comprises a feed and dispensing system (12), a priming system (20) and a control system. The feed and dispensing system (12) feeds a belt (14) of incendiary capsules (16) to a region at which individual capsules are separated from the belt and dispensed from the machine (10). The priming system (20) primes the capsule (16) prior to being dispensed from the machine (10) with a priming liquid which, when delivered into a capsule, facilitates an exothermic reaction. The control system controls the feed and dispensing system (12), and the priming system (20) independently of each other so that the belt (14) can be fed into and indeed thought the machine (10) with the priming liquid being injected into the capsules.Type: ApplicationFiled: March 2, 2011Publication date: March 14, 2013Inventor: Robert Andrew Stevenson

Patent number: 8249071Abstract: A system for management and control of audio related equipment. The system provides an architecture to manage, monitor, and control all of the audio related equipment in an audio system. A communication protocol used within the system allows standardized communication between the performance equipment mangers and the audio related devices, as well as device-to-device communication.

Publication number: 20120145830Abstract: An incendiary capsule has a body forming a single compartment containing a first part of a two part ignition system and a quantity of a pyrotechnic heat source (PHS). The capsule is initiated by injecting, when ready for use, a quantity of a second part of the two part ignition system. The ignition system generates sufficient heat to initiate the PHS, which burns at a substantially higher temperature than the ignition system.Type: ApplicationFiled: June 4, 2010Publication date: June 14, 2012Inventors: Robert Andrew Stevenson, Vincenzo Foti

Patent number: 8078298Abstract: A system for determination of the functionality of an audio-related device that is operable in an audio system includes a performance equipment manager. The performance equipment manager may receive from an audio-related device an audio node structure representative of the corresponding audio-related device. The received audio node structure may be reviewed to determine if all the components included in the audio node structure are predefined within the performance equipment manager. For those components that are known, no discovery is necessary and actual values of changeable parameters in the audio-related device may be obtained. For unknown components of the audio node structure, the performance equipment manager may undertake discovery to identify additional portions of the audio node structure, and/or attributes related to the unknown components, in order to obtain actual values of changeable parameters related to the unknown components.Type: GrantFiled: March 25, 2005Date of Patent: December 13, 2011Assignee: Harman International Industries, IncorporatedInventors: Richard Allen Kreifeldt, John Lee, William A.

Patent number: 7742606Abstract: A system for management and control of audio-related equipment. The system is a common architecture that provides the capability to manage, monitor and control all of the audio-related equipment in an audio system. To facilitate messaging between audio-related devices, each of the audio-related devices may be assigned a node ID a sequential manner as each audio-related device powers up. The system may also include a method for discovery of audio-related devices on an audio network. In some examples, a PEM may be located geographically remote from the audio-related devices. Accordingly, error logging, alarming and system operation may be monitored to provide troubleshooting from a remote location.Type: GrantFiled: March 25, 2005Date of Patent: June 22, 2010Assignee: Harman International Industries, IncorporatedInventors: Richard Allen Kreifeldt, John Lee, William A.

Patent number: 7725826Abstract: A system may instantiate a control panel view that is useable to monitor and control an audio-related device operable in an audio system. A product plugin that corresponds to an audio-related device may receive and analyze the components of an audio node structure received from the audio-related device. The product plugin is configured to store one or more predefined control panel views that are associated with one or more of the components. The product plugin is also configured to instantiate the predefined control panel views that correspond to the components. If the product plugin determines that all of the components are not represented, one or more user interface aspects can be integrated into one or more of the control panel views prior to instantiation. Alternatively, a generic control panel view can be generated.Type: GrantFiled: March 25, 2005Date of Patent: May 25, 2010Assignee: Harman International Industries, IncorporatedInventors: Richard Allen Kreifeldt, John Lee, William A.

Patent number: 7689305Abstract: A system for communication among audio-related devices in an audio system includes a performance equipment manager that communicates with audio-related devices to monitor and control changeable parameters of a corresponding audio-related device. Each of the audio-related devices includes an audio node structure having components that are representative of the functionality of the respective audio-related device. Some of the components are representative of changeable parameters in the audio-related device. The performance equipment manager is configured to be selectively subscribed to one or more of the changeable parameters so that when a predefined condition occurs, the audio-related device is configured to automatically provide the current value of the changeable parameter(s) to the performance equipment manager.Type: GrantFiled: March 25, 2005Date of Patent: March 30, 2010Assignee: Harman International Industries, IncorporatedInventors: Richard Allen Kreifeldt, John Lee, William A.
