Energy-efficient on-node signal processing for vibration monitoring [PDF]

2014 IEEE Ninth International Conference on Intelligent Sensors, Sensor Networks and Information Processing (ISSNIP), 2014
In recent years, the use of wireless sensor networks for vibration monitoring is emphasized, because of its capability to continuously monitor at hard-to-reach locations of complex machines. Low power consumption is one of the main requirements for the sensor nodes in continuous and long-term vibration monitoring.

Integrate-and-fire circuit for converting analog signals to spikes using phase encoding [PDF]

Neuromorphic Computing and Engineering (2023), 2023
Processing sensor data with spiking neural networks on digital neuromorphic chips requires converting continuous analog signals into spike pulses. Two strategies are promising for achieving low energy consumption and fast processing speeds in end-to-end neuromorphic applications. First, to directly encode analog signals to spikes to bypass the need for

An Energy Scalable Functional Unit for Sensor Signal Processing [PDF]

2007 IEEE International Conference on Acoustics, Speech and Signal Processing - ICASSP '07, 2007
Low power signal processing functionality is required for wireless sensor network nodes due to their limited battery life. Previously, we have proposed a reconfigurable array of DSP acceleration functional units for such a sensor node. The array maximizes operating life by matching system power consumption to available energy through power scalable ...

System for powering autonomous solar cookers by batteries

Scientific African, 2022
In this paper, we propose innovative autonomous solar cookers (hot plates and box ovens) supplied by batteries. The electrical energy is produced by photovoltaic panels (PV) and stored in a battery (24 V, 520 Ah). Hence, the cookers are powered through a
