Abstract: A grooved electrode adapted for interfacing cellular matter is provided. The grooved electrode includes grooves adapted for electrically interfacing the grooved electrode with cellular matter growing along the body of the grooved electrode. Further, the grooved electrode includes a wireless transponder adapted to electrically interface with cellular matter and to relay such interactions via RF signals. The RF signals received by the wireless transponder are modulated in response to electrical signals generated by the cellular matter, which are detected by the transponder. The grooved electrode may be implanted within peripheral nerves for treating various neurological conditions, which may include nerve rehabilitation and prosthetic actuation, severe pain, obstructive sleep apnea and so forth.
Abstract: A continuous preparation of calcium hydroxide slurry can be made on a mobile apparatus that uses an eductor to initially combine metered flows of calcium oxide and water. The calcium hydroxide slurry is retained in a deaerating sump and then pumped into a serpentine centrifugal mixer so that the reaction of the calcium oxide and the water is safely complete. Because the apparatus allows the calcium hydroxide slurry to be recirculated into the deaerating sump, the slaking process can continue even when it is necessary to pause the discharge of slurry to change transport tankers.
