Absolutely optimum array filters for sensor arrays
IEEE Transactions on Acoustics, Speech, and Signal Processing, 1985A family of array filters is derived for processing the recorded measurements of an array of sensors with the purpose of attenuating coherent noise interfering with a desired signal. One member of this family is the absolutely optimum array filter (AOAF), which minimizes the magnitude squared of the array rejection response subject to an all-pass ...

A Microfluidic Ion Sensor Array
Small, 2020AbstractA balanced concentration of ions is essential for biological processes to occur. For example, [H+] gradients power adenosine triphosphate synthesis, dynamic changes in [K+] and [Na+] create action potentials in neuronal communication, and [Cl−] contributes to maintaining appropriate cell membrane voltage.

A transparent oxygen sensor array
Annals of Biomedical Engineering, 1986The development of a transparent array of independently connected oxygen sensors is described. With an appropriate sensor pattern, this device may be useful to monitor the distribution of oxygen on the surface of tissues, while permitting simultaneous tissue visualization.

Current Opinion in Biotechnology, 2012
Motivated by the advantages endowed by high-throughput analysis, researchers have succeeded in incorporating multiple reporter cells into a single platform; the technology now allows the simultaneous scrutiny of a large collection of sensor strains. We review current aspects in cell array technology with emphasis on microbial sensor arrays. We consider

MONITORING BEHAVIOR WITH AN ARRAY OF SENSORS
Computational Intelligence, 2007The objective is to detect activities taking place in a home and to create a model of behavior for the occupant. A behavior is a pattern in the sequence of activities. An array of sensors captures the status of appliances. Models for the occupant's activities are built from the captured data using supervised and unsupervised learning techniques.

Decentralized processing in sensor arrays
IEEE Transactions on Acoustics, Speech, and Signal Processing, 1985We present a new scheme for decentralized processing in passive sensor arrays based on communicating the sample-covariance matrices of the subarrays. The new scheme offers improved accuracy over the conventional triangulation scheme with only a modest increase in the communication load.

The performance of the optimum array filter for sensor arrays
ICASSP '87. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005A theoretical analysis of the performance of optimum array filter (AOAF) for sensor arrays, which is proposed by Hanna and Simaan is presented. The beam pattern of array processing system not only depends on the rejection response, but also the model mismatch.

Acoustic vector sensor array processing
[1992] Conference Record of the Twenty-Sixth Asilomar Conference on Signals, Systems & Computers, 1994An approach is proposed for localization of acoustic sources using an array of sensors for which the measurement of each sensor is a vector consisting of the acoustic pressure and acoustic particle velocity. A compact expression is derived for the Cramer-Rao bound (CRB) on the estimation errors of the source direction-of-arrival (DOA) parameters in the
