Low-Power, High Data Rate Transceiver System for Implantable Prostheses

open access: yesInternational Journal of Telemedicine and Applications, 2010
Wireless telemetry is crucial for long-term implantable neural recording systems. RF-encoded neurological signals often require high data-rates to transmit information from multiple electrodes with a sufficient sampling frequency and resolution.

An optimisation study of a solar tower receiver: the influence of geometry and material, heat flux, and heat transfer fluid on thermal and mechanical performance

open access: yesHeliyon, 2021
The solar receiver is considered the cornerstone of the solar tower power system. In particular, it receives high-temperature heat flux rays, and extracts the maximum heat energy to be transferred to the heat transfer fluid, while minimising any thermal ...

The external ears as receiving antennas in echolocating bats [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1982
The external ears of bats appear to vary greatly in size and shape, but they in fact have dimensions specifically related to the structure of sonar sounds in different species. They determine the directionality of hearing and produce cues for vertical target localization.
