Abstract: System, circuits, and methods to reduce or eliminate uncompensated voltage drop between an electrode of an electrochemical cell usable for analyte measurement. In one example, a system is provided that includes a test strip, a reference voltage circuit, an operational amplifier connected to the reference voltage circuit to provide a pre-determined fraction of a reference voltage substantially equal to the test voltage applied to the first line, the operational amplifier having an output configured for one of a connected or disconnected state to the first line, and a processing circuit connected to the output of the operational amplifier and the first line such that, during a disconnected state between the output and the first line, the processing circuit remains in connection with the first line. In another example, a method of measuring an electrochemical reaction of an electrochemical cell is provided that includes applying a test voltage to the first electrode and connecting the second electrode to ground; uncoupling the first electrode from the output of the circuit while allowing electrical communication from the first electrode to the processor; and coupling the first electrode to the output to measure a test current generated in the electrochemical cell without an uncompensated voltage drop.

Title: Tool face sensor method
Inventor: DOWNTON GEOFF

Filed: 2008-07-25
Granted: 2012-09-18
Abstract: Exhaust pressure from at least one actuator (34,36) which can tilt joint 6 of a bottom hole assembly 4 can be utilized to determine the direction 26 tiltable joint 6 is pointing (e.g., orientation, angular displacement, and/or inclination and azimuth). In one embodiment, a known exhaust pressure can be correlated to a known orientation and/or angular displacement, and the measured exhaust pressure can be compared to the known exhaust pressure to determine the orientation and/or angular displacement. In another embodiment, the flow rate of fluid exhausted from an actuator (34,36) can be derived from the exhaust pressure. The exhaust flow rate can then be used to calculate the state of actuation, which can allow determination of the angular displacement of the tiltable joint 6. Orientation and/or angular displacement with respect to the bottom hole assembly 4 can be resolved into an inclination and azimuth with respect to a formation 14.

Granted: 2015-10-20
Abstract: An exploitation of the proper classification of conventional call-processing states into categories, each category corresponding to one of the call states of the SIP finite- state machine (FSM), yields simplified design, implementation, and operation of heterogeneous call processing. A separate FSM for the S I P- categorized call states, running in parallel with a conventional port event processing (PEP) FSM, implements a VoIP Local Call Controller by passing events between the SIP-type FSM and the PEP FSM only at the points where a transition between SIP categories occurs. The SIP FSM does not require notification of PEP FSM transitions not affecting the SIP call state. For this reason, none of the code associated with the transitions between PEP FSM states within the same major state category requires any modification. Consequently the integration of VoIP and PEP call processing can be done more simply, and at dramatically-reduced cost in software development, support, and maintenance.
