Abstract: An electronic system for a drug delivery device is provided, the electronic system comprising at least one user interface member configured to be manipulated by a user for performing a dose operation, e.g.

Abstract: A material separation system is disclosed that may include a vibratory shaker, a centrifuge, a sensor, and/or a processor circuit. The vibratory shaker may be configured to separate a solid-liquid mixture into a first solids-containing component and a shaker effluent. The sensor may be configured to measure a property of one or more of the solid-liquid mixture, the first solids-containing component, the shaker effluent, and the second solids-containing. A well-performance analysis system may be configured to analyze mud reports of drilling rigs within a geographic basin to determine which rigs are performing inefficiently. The system may allow recommendations and send control signals to improve the efficiency of the solid-liquid separation system.

Abstract: A circuit for efficiently time-sharing the output and input configuration of a microprocessor I/O pin. The circuit includes a microprocessor having at least one I/O pin which can be selectively reconfigured for either output or input functions, a pull-up resistor, a dropping resistor and an output device. The pull-up resistor, dropping resistor and output device each have a common electrical connection at a terminal connected to the selected I/O pin. The pull-up resistor also has a terminal connected to the regulated power supply (Vcc) of the circuit. An input device or configuration switch, which is selectable between a first state and a second state, has one terminal connected to the dropping resistor and a second terminal connected to a point of the circuit at ground potential. The selected I/O pin is normally configured as an output pin for controlling the output device.
