    摘要: A telemetry system is presented for enabling radio-frequency (RF) communications between an implantable medical device and an external device in a manner which reduces the power requirements of the implantable device by duty cycling its RF circuitry. A wakeup scheme for the implantable device is provided in which the external device transmits a data segment containing a repeating sequence of special wakeup characters in order to establish a communications session with the implantable device. The wakeup scheme may be designed to operate in the context of a handshaking protocol for collision avoidance.

    摘要: A mixing fin assembly of a type used in transit concrete mixing vehicles which includes a spiral mixing fin designed to extend transversely into a drum mixing space. The fin is constructed of a lightweight, moldable polymeric material which is flexible and resistant to abrasion and includes a plurality of conjoined sections that fit together usin locking tabs and mating fin locking sockets at the ends of the sections. The mixing fin may be mounted into a metal mixing drum using a spiral fin mount rail track fixed to the interior surface of the drum and which fits into a track locking socket or slot recess. Preferably, a locking tab locks the upper part of the rail track into the fin structure is included. The fin mount rail track and the spiral mixing fin preferably have aligned weep opening when assembled to enable free flow of material along the inside surface of the drum.
