    Abstract: The invention discloses an automated liquid level sensing system for detecti ng the presence of liquid in a container, comprising an electrically conductive and movable probe positioned above said container; a signal source electrically connected to said probe, said signal source capable of energizing said probe thereby causing said probe to transmit said electrical signal at a given frequency; a receiving antenna and means for transferring said received electrical signal from said receiving antenna to an analyzing means; wherein analyzing said received electrical signal includes: (1) means for detecting changes in received signal amplitude, wherein said means for detecting changes in received signal amplitude includes:(a) means for multiplying said received signal by a reference signal, said reference signal having a frequency substantially equal to the frequency of the transmitted signal; and (b) a low pass filter through which is passed said multiplied received signal; and (2) means for measuring rate of change of said change in received signal amplitude; and means connected to said analyzing means for indicating that liquid has been detected. The invention further discloses a method of automatically detecting the presence of liquid in a container using the system of the invention. An automated liquid sensing system for us e in a clinical analysis system having a pipettor for dispensing or aspirating liqu id in a container, the pipettor being electrically conductive and moveable verticall y into the container, using the automated liquid sensing system of the invention furthe r comprising a means electrically connected to the pipettor for applying a RF signal thereto and causing the pipettor to radiate an electromagnetic field, the propagation of which changes when the pipettor contacts the surface of the liquid in the container is further disclosed.

    Abstract: A cartridge feeder apparatus for automated diagnostic systems has a cartridge hopper means for receiving, storing and feeding cartridges to a cartridge orientation mechanism; the cartridge orientation mechanism comprised of two opposed engageable orientation means for engaging and disengaging a cartridge at each end of the cartridge; and the cartridge havi ng a funnel opening at a first end and a generally flat bottom at a second end; i n a particular embodiment a feeder is for dispensing a plurality of cartridges i n single order and upright position, each cartridge being cylindrical in shape and having a top end tapering to an aperture therein and a substantially flat bottom end, the apparatus comprising: a first pin and a second pin axially aligned, each of the pins having mounted on one end thereof a cup, each cup having a center profile that matches the shape of the top end of the cartridge, the cups facing each other; means for supporting the first and second pins, the pins being axially slidable in the supporting means such that the pins can releasably support one of the cartridges therebetween regardless of the orientation of the top and bottom ends of the cartridge; and means for actuating the first and second pins, the actuating means fixed to the supporting means, the actuatin g means capable of closing the pins against the top and bottom ends of said cartridge whereby the center profile of one of the cups fits into the top en d of the cartridge with the other cup pressing against the bottom end of the cartridge, and the actuating means being capable of opening the pins away from the top and bottom ends of the cartridge to release the cartridge, whereby one cup holds the top end of the cartridge while the bottom end of the cartridge slips downwardly from the other cup causing the cartridge to pivot to the upright position embodiment.
