20080240266 | Arrangements for monitoring and controlling a transmission path - In one embodiment of the present disclosure, a method for improving communication between a transmitter and a receiver is disclosed. The method can include receiving a first signal having a first power level over a first path, receiving a second signal having a second power level over a second path wherein the first path is different than the second path. The method can compare the first power level with the second power and determine a difference between the first power level and the second power level. The method can also adjusting a parameter in the system to reduce the difference in power levels between the first and second signals compensating for interference cause by many sources. | 10-02-2008 |
20080240313 | Closed Loop Adaptive Clock RFI Mitigation - A method according to one embodiment for mitigating radio frequency interference by identifying system clocks, identifying active radio channels, measuring clock harmonics in or near the active radio channels, determining potential interference occurring if the clocks were moved to new fundamental frequencies, and shifting clock fundamental frequencies to reduce interference to the active radio channels based on existing interference and the potential interference of a plurality of new fundamental frequencies. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment. | 10-02-2008 |
20090080498 | ADAPTIVE RADIO FREQUENCY INTERFERENCE MITIGATION DURING CHANNEL SCANNING OR HOPPING - In some embodiments an adaptive clock controller is to determine clock interference associated with a channel changing pattern for a radio in a computing platform, and to determine an earliest switching time of a clock of the computing platform. A clock generator is to change a frequency of the clock in response to the determined clock interference and in response to the earliest switching time. Other embodiments are described and claimed. | 03-26-2009 |
20090169018 | HANDHELD DEVICE ASSOCIATION VIA SHARED VIBRATION - In some embodiments an accelerometer is mechanically coupled to a first device. The accelerometer obtains a vibration profile in response to a relative movement of the first device and a second device. A radio transmits an encrypted version of the vibration profile to the second device and receives an encrypted version of a vibration profile from the second device. A processor sets up a secure channel between the radio and the second device in which to exchange keys with the second device in order to decrypt the received encrypted vibration profile. The processor also decrypts the received encrypted vibration profile in response to at least one of the exchanged keys, compares the transmitted vibration profile with the received vibration profile and allows a sharing of resources with the second device if a match occurs between the transmitted vibration profile and the received vibration profile. Other embodiments are described and claimed. | 07-02-2009 |
20100169075 | ADJUSTMENT OF TEMPORAL ACOUSTICAL CHARACTERISTICS - Embodiments may be a standalone module or part of mobile devices, desktop computers, servers, stereo systems, or any other systems that might benefit from condensed audio presentations of item structures such as lists or tables. Embodiments may comprise logic such as hardware and/or code to adjust the temporal characteristics of items comprising words. The items maybe included in a structure such as a text listing or table, an audio listing or table, or a combination thereof, or may be individual words or phrases. For instance, embodiments may comprise a keyword extractor to extract keywords from the items and an abbreviations generator to generate abbreviations based upon the keywords. Further embodiments may comprise a text-to-speech generator to generate audible items based upon the abbreviations to render to a user while traversing the item structure. | 07-01-2010 |
20110293054 | ADAPTIVE CONTROL OF CLOCK SPREAD TO MITIGATE RADIO FREQUENCY INTERFERENCE - In some embodiments an adaptive clocking controller determines a clock spread of a system clock that would result in a lowest total interference between a channel received by a radio receiver and the system clock. A clock generator modifies a spread of the system clock in response to the determined clock spread. Other embodiments are described and claimed. | 12-01-2011 |
20140188470 | FLEXIBLE ARCHITECTURE FOR ACOUSTIC SIGNAL PROCESSING ENGINE - A disclosed speech processor includes a front end to receive a speech input and generate a feature vector indicative of a portion of the speech input and a Gaussian mixture (GMM) circuit to receive the feature vector, model any one of a plurality of GMM speech recognition algorithms, and generate a GMM score for the feature vector based on the GMM speech recognition algorithm modeled. In at least one embodiment, the GMM circuit includes a common compute block to generate feature a vector sum indicative of a weighted sum of differences squares between the feature vector and a mixture component of the GMM speech recognition algorithm. In at least one embodiment, the GMM speech recognition algorithm being modeled includes a plurality of Gaussian mixture components and the common compute block is operable to generate feature vector scores corresponding to each of the plurality of mixture components. | 07-03-2014 |
20140236582 | LOW POWER VOICE DETECTION - Methods of enabling voice processing with minimal power consumption includes recording time-domain audio signal at a first clock frequency and a first voltage, and performing Fast Fourier Transform (FFT) operations on the time-domain audio signal at a second clock frequency to generate frequency-domain audio signal. The frequency domain audio signal may be enhanced to obtain better signal to noise ratio, through one or multiple filtering and enhancing techniques. The enhanced audio signal may be used to generate the total signal energy and estimate the background noise energy. Decision logic may determine from the signal energy and the background noise, the presence or absence of the human voice. The first clock frequency may be different from the second clock frequency. | 08-21-2014 |
20140270197 | LOW POWER AUDIO TRIGGER VIA INTERMITTENT SAMPLING - Systems and methods may provide for using an audio front end of a mobile device to sampled audio from an audio signal during a first portion of a periodic detection window, and reducing a power consumption of one or more components of the audio front end during a second portion of the periodic detection window. Additionally, a determination may be made as to whether voice activity is present in the audio signal based at least in part on the sampled audio. In one example, the length of the first portion and the length of the second portion are defined by a duty cycle of the periodic detection window. | 09-18-2014 |
