20090328048 | Distributed Processing Architecture With Scalable Processing Layers - The present invention is a system on chip architecture having scalable, distributed processing and memory capabilities through a plurality of processing layers. In a preferred embodiment, a distributed processing layer processor comprises a plurality of processing layers, a processing layer controller, and a central direct memory access controller. The processing layer controller manages the scheduling of tasks and distribution of processing tasks to each processing layer. Within each processing layer, a plurality of pipelined processing units (PUs), specially designed for conducting a defined set of processing tasks, are in communication with a plurality of program memories and data memories. One application of the present invention is in a media gateway that is designed to enable the communication of media across circuit switched and packet switched networks. The hardware system architecture of the said novel gateway is comprised of a plurality of DPLPs, referred to as Media Engines that are interconnected with a Host Processor or Packet Engine, which, in turn, is in communication with interfaces to networks. Each of the PUs within the processing layers of the Media Engines are specially designed to perform a class of media processing specific tasks, such as line echo cancellation, encoding or decoding data, or tone signaling. | 12-31-2009 |
20110085656 | Method and System for Filtering a Signal and for Providing Echo Cancellation - The present invention provides for adaptive filters that have improved computational and memory bandwidth proprieties. When applied to telecommunication applications, the present invention additionally provides for improved methods and systems of canceling echoes. In one embodiment of the adaptive filter of the present invention, a filter, preferably an adaptive finite impulse response (FIR) filter, of an appropriate length, N, is chosen. Once the filter is chosen, convergence is achieved and the filter is converted to an infinite impulse response (IIR) filter. In the course of operation, data is received from an input source and used to adapt the zeroes of the IIR filter using the least means square (LMS) approach, keeping the poles fixed. The adaptation process generates a set of converged filter coefficients that are then applied to the input signal to create a modified signal used to filter the data. The novel adaptive filter method and system presented herein can be used to improve the calculation of the echo impulse response by, among other things, reducing the computational complexity and memory requirements of the coefficient calculation conducted within the adaptive filter. | 04-14-2011 |

20150193040 | Hover Angle - Example apparatus and methods concern detecting an angle at which an object is interacting with a hover-sensitive input/output interface. An example apparatus may include a proximity detector configured to detect an object in a hover-space associated with the hover-sensitive input/output interface. The proximity detector may provide three dimensional position information for the object (e.g., x,y,z). The angle may be determined from a first (x,y,z) measurement associated with a first portion (e.g., tip) of the object and a second (x,y,z) measurement associated with a second portion (e.g., end) of the object. The position of the object may determine a hover point on the interface while the position and angle may determine an intersection point on the interface. User interface elements or other information displayed on the interface may be manipulated based, at least in part, on the intersection point. Multiple objects interacting at multiple angles may be detected and responded to. | 07-09-2015 |
20150205400 | Grip Detection - Example apparatus and methods detect how a portable (e.g., handheld) device (e.g., phone, tablet) is gripped (e.g., held, supported). Detecting the grip may include detecting and characterizing touch points for fingers, thumbs, palms, or surfaces that are involved in supporting and positioning the apparatus. Example apparatus and methods may determine whether and how an apparatus is being held and then may exercise control based on the grip detection. For example, a display on an input/output interface may be reconfigured, physical controls (e.g., push buttons) on the apparatus may be remapped, user interface elements may be repositioned, resized, or repurposed, portions of the input/output interface may be desensitized or hyper-sensitized, virtual controls may be remapped, or other actions may be taken. Touch sensors may detect the pressure with which a smart phone is being gripped and produce control events (e.g., on/off, louder/quieter, brighter/dimmer, press and hold) based on the pressure. | 07-23-2015 |
