Abstract: A device for estimating a mechanical property of a sample is disclosed herein. The device may include a chamber configured to hold the sample; a transmitter configured to transmit a plurality of waveforms, including at least one forcing waveform; and a transducer assembly operatively connected to the transmitter and configured to transform the transmit waveforms into ultrasound waveforms. The transducer assembly can also transmit and receive ultrasound waveforms into and out of the chamber, as well as transform at least two received ultrasound waveforms into received electrical waveforms.

Abstract: A disposable system, in some embodiments, includes a multi-channel or multi-chamber test cartridge device configured to operate with a testing system for evaluation of hemostasis in a subject by in vitro evaluation of a test sample from the subject. The disposable system, in some embodiments, is configured to interrogate the test sample to evaluate clot stiffness, strength, or other mechanical properties of the test sample to assess the function of various physiological processes occur during coagulation and/or dissolution of the resulting clot.

Abstract: This invention provides a quick-placement EEG electrode. The EEG electrode is fixed to a patient's scalp by a first element working in conjunction with a second element to trap hair and hold the EEG electrode in place. The EEG electrode contains a sponge that when compressed, dispenses electrolytic gel, acts as a shock absorber, and maintains contact with the scalp. The EEG electrode has a quick release mechanism for easy removal of the EEG electrode from the patient's scalp.
