Patent number: 8804037Abstract: Systems, methods, and processor readable media are disclosed for encoding and transmitting first media content and second media content using a digital radio broadcast system, such that the second media content can be rendered in synchronization with the first media content by a digital radio broadcast receiver. The disclosed systems, methods, and processor-readable media determine when a receiver will render audio and data content that is transmitted at a given time by the digital radio broadcast transmitter, and adjust the media content accordingly to provide synchronized rendering. In exemplary embodiments, these adjustments can be provided by: 1) inserting timing instructions specifying playback time in the secondary content based on calculated delays; or 2) controlling the timing of sending the primary or secondary content to the transmitter so that it will be rendered in synchronization by the receiver.Type: GrantFiled: February 21, 2012Date of Patent: August 12, 2014Assignee: iBiquity Digital CorporationInventors: Steven Andrew Johnson, Muthu Gopal Balasubramanian, Harvey Chalmers, Jeffrey Ranken Detweiler, Albert Gambardella, Russell Iannuzzelli, Stephen Douglas Mattson

Patent number: 8660479Abstract: A digital radio broadcast system includes a processing system that receives first audio content, first program data identifying a first item for the first audio content, second audio content, and second program data identifying a second item for the second audio content such that a start of the first program data is received at the processing system within 0.5 seconds of a start of the first audio content. A digital radio broadcast signal including the audio content and the program data is processed for digital radio broadcast transmission via a transmitter. The processing system stops delivery of the first program data to the transmitter upon receipt of the second program data, the first program data thereby being truncated, and begins delivery of the second program data to the transmitter. A digital radio broadcast receiver can tag content of interest based on a user command registered at the receiver.Type: GrantFiled: August 2, 2010Date of Patent: February 25, 2014Assignee: iBiquity Digital CorporationInventors: Steven Andrew Johnson, Robert Michael Dillon, Harvey Chalmers

Patent number: 5882379Abstract: A dust collector system includes a conduit defining an interior volume, having a first open end, and including an air vent. A pressure differential detector includes a first air flow tap, a second air flow tap, and a pressure differential indicator. The first air flow tap is connected to a dust filter unit dirty air plenum. The second air flow tap is connected to the sensor conduit internal volume at a portion above a location corresponding to a level of collected dust to be detected. The pressure differential detector indicates a presence of at least a selected pressure differential between the first and second air flow taps. When a level of dust in the dust collection container reaches a selected level, it will close the sensor conduit first end. When the sensor conduit first end is closed, a pressure within the sensor conduit internal volume will rise towards atmospheric as a result of the air flow through the air vent.Type: GrantFiled: September 26, 1997Date of Patent: March 16, 1999Assignee: Donaldson Company, Inc.Inventor: Steven Andrew Johnson

Patent number: 5721543Abstract: An encoder and decoder system for compressing discrete data sequences is disclosed. The encoder includes a self-affine map generator and a backward adaptive map generator which model source vectors formed from a discrete data sequence. The self-affine map generator uses known modeling techniques to determine map parameters for mapping functions. The mapping functions are evaluated by computing a collage error and the mapping function corresponding to the smallest collage error is selected. The backward adaptive map generator determines map parameters for mapping functions which map vectors previously generated to represent the discrete data sequence to the source vector. A distance measurement is computed for each target vector/mapping function combination and the mapping function corresponding to the smallest distance measurement is selected.Type: GrantFiled: June 30, 1995Date of Patent: February 24, 1998Assignee: Iterated Systems, Inc.Inventors: Steven Andrew Johnson, Li-Zhe Tan, Sing-Wai Wu
