A single plate capacitive bubble detection sensor. The detector may employ a single active plate. A parasitic capacitance of the active plate relative to the environment may be monitored without reference to any particular ground source. In this regard, highly sensitive measurements may be made of a tube disposed adjacent to the active plate to detect, for example, the presence of air, liquid, or a change between liquid and air in the tube.

Syringe positioning apparatus and methods are disclosed that provide for automated positioning of a syringe at an axially aligned position on a predetermined axis. The apparatus and methods employ first and second members having opposing surfaces that include first and second ramps, respectively, wherein the first ramp angles upward and away from the second member, and the second ramp angles upward and away from the first member. At least one of the first and second members may be advanceable toward the other by an actuator, wherein the first and second ramps may slidably engage a syringe and thereby elevate the syringe to the axially aligned position on the predetermined axis.

A source fluid inlet for an automated filling device. The source fluid inlet may comprise features that limit engagement and/or disengagement of a source fluid tubing set from a port in the source fluid inlet except when the port is disposed in a predetermined load position. In turn, engagement and/or disengagement of the source fluid tubing may be selectively allowed to assist in reduction of interconnection errors of one or more source fluid sources. The source fluid inlet may selectively position a source fluid tubing set in a fill position to facilitate fluid communication with a receptacle to be filled (e.g., a syringe). The source fluid inlet further comprises one or more mechanisms for engagement and/or retention of a cap disposed on a syringe.

A method of providimg two-way communication between a plurality of channel units in a channel bank and a line interface circuit of a telephone system utilizing a receive direction protocol and a separate transmit direction protocol. The receive direction protocol identifies the channel unit to which provisioning data is to be delivered, increases the bandwidth of the voice data region in the time slot corresponding to the identified channel unit, superposes the provisioning data in the time slot with the voice data, and delivers the superposed data to the channel unit wherein the provisioning data is separated from the voice data. The transmit direction protocol utilizes the A and B signaling bits corresponding to the eighth bit of an identified time slot in the sixth and twelfth transmit frames wherein two bits of an eight bit status message is delivered on every other superframe. The two-way communication protocols occur without affecting or interfering with the PCM voice data.
