Abstract: A vacuum insulation panel (VIP) in an example comprises first and second walls and a plurality of tensile elements. The first and second walls are structurally coupled to allow formation of a vacuum cavity between the first and second walls. The plurality of tensile elements structurally supports the first and second walls against external pressure contemporaneous with tension on the plurality of tensile elements. The plurality of tensile elements is located in the vacuum cavity between the first and second walls.

Abstract: A radio frequency identification (RFID) reader of an apparatus in an example employs substantially synchronized sampling to obtain a signal from an RFID card notwithstanding employment by the RFID card of any of amplitude shift keying (ASK), frequency shift keying (FSK), or phase shift keying (PSK). The RFID reader decodes the signal notwithstanding the employment by the RFID card of any of ASK, FSK, or PSK.

Abstract: A blind adaptive filter of an apparatus in an example employs a frequency domain ECG-feature vector and a time domain ECG feature vector with a maternal ECG parameter estimate and a set of candidate fetal ECG estimates that satisfy the frequency domain ECG-feature-vector, to extract a fetal ECG signal estimate from raw abdominal ECG signals of a pregnant female. The fetal ECG signal estimate satisfies the frequency domain ECG feature-vector and the time domain ECG feature vector.
