SYSTEM AND METHOD FOR OPTIMIZING SIGNAL PROCESSING AND STORAGE USING FREQUENCY-TIME DOMAIN CONVERSION
An audio processing system and method of operating the system are provided. The system includes a memory storing a plurality of frequency domain sound recording samples represented and stored in a frequency domain and being previously converted from a plurality of sound recording samples represented in a time domain. The system also includes at least one processing unit coupled to the memory and is configured to read the plurality of frequency domain sound recording samples from the memory. The at least one processing unit is also configured to process the plurality of frequency domain sound recording samples.
Method for offset calibration of a yaw rate sensor signal of a yaw rate sensor, system and computer program
A method for offset calibration of a rotation rate sensor signal of a rotation rate sensor. In a first step, an ascertainment is made that the rotation rate sensor is in an idle state. In a second step, after the first step, a filter parameter is determined as a function of the measured rotation rate sensor values, measured in the idle state, of the rotation rate sensor. In a third step, after the second step, a filtered measured rotation rate sensor value is determined with the aid of the filter parameter. An offset is determined with the aid of the filtered measured rotation rate sensor value.
Frequency encryption for communication signals
A receiver in a communication system may include a buffer and hardware. The buffer may be configured to store a communication signal comprising one or more pulses representative of data. The hardware may be configured to determine whether a data authentication pulse has been superimposed over at least one of the one or more pulses, and authenticate, based on the determination of whether the data authentication pulse has been superimposed over at least one of the one or more pulses, the one or more pulses as a valid representation of the data.

Adaptive filter bank for modeling a thermal system
Embodiments of the disclosure implement an application of an adaptive filter bank that is used to characterize the heat transfer of a volume in a thermal system, to estimate temperature and power consumption, and to improve performance characteristics in applications including optimal temperature control and diagnostics. In some embodiments, the adaptive filter bank is an iterative solution, comprised of a collection of adaptive filters defined to consume incident signals, produce an aggregate reference signal, estimate an error relative to an observed primary signal, and modify thermal coefficients to converge on a solution. For example, the incident signals are comprised of properties related to active, passive, solar irradiance, and unobserved heat transfer. A reference signal is an estimate of a primary signal, related to the rate of heat transfer or temperature change. Thereupon, the thermal coefficients are modified in an adaptive process to include gradient descent, which minimizes estimation error.

Genetic-Algorithm-Based Equalization Using IIR Filters
Systems and methods utilize a modified genetic algorithm for adapting an off-the-shelf audio system, such as in a high-end television, to a given, particular room or other physical location presenting a specific or unique auditory environment with a set of acoustic properties. An audio system is adapted to a given room by determining an IIR based EQ solution via iterative techniques, including an iterative technique based upon a genetic algorithm adapted for an audio frequency response equalization application. In a variant, an audio system is adapted to a particular room, adjust the EQ across a microphone's bandwidth while preserving the factory-calibrated EQ response across the remaining bandwidth.

Multi-thread power limiting via shared limit
Systems and methods for multi-thread power limiting via a shared limit estimates power consumed in a processing core on a thread-by-thread basis by counting how many power events occur in each thread. Power consumed by each thread is approximated based on the number of power events that have occurred. Power consumed by individual threads is compared to a shared power limit derived from a sum of the power consumed by all threads. Threads that are above the shared power limit are stalled while threads below the shared power limit are allowed to continue without throttling. In this fashion, the most power intensive threads are throttled to stay below the shared power limit while still maintaining performance.
