  • Patent number: 6868309
    Abstract: A method and control system computing platform for a dialysis machine that uses Symmetric Multi-Processing (SMP) architecture. The SMP architecture tightly couples multiple (e.g., 2) independent processors by sharing memory between the processors. A single shared memory is used by both processors in order to facilitate communication between the processors and reduce cost by eliminating the expense of redundant memory. In this way, the two, or in general “N” processors, increase processor throughput by allowing the execution of N processes in parallel while without requiring extra memory and without having a single point of failure in the computer. In the event of a bus failure on the circuit card, the computer is reset using distributed hardware watchdogs. The watchdog reset signal is also sent to the hardware components of the dialysis machine in order to place the system in a safe.

First and second controllers provide pulse width modulated signals, modulated with respect to first and second clock signals, respectively, to the respective first and second inverters. A capacitor coupled between a power bus and a ground bus smoothes power bus ripples caused by simultaneous switching. To reduce the size needed for the capacitor, different modulation schemes, such as center based interleaved, and leading and lagging edge coincident, are used when both motors are in the motoring mode or both motors are in the regeneration mode. However, the same modulation scheme is used when one motor is in the motoring mode and the other motor is in the regeneration mode.

  • Patent number: 6823219
    Abstract: An architecture for use in controlling and managing optical functions and optical devices. A common microprocessor based control layer coordinates commands between optical devices and a user station. The control layer executes an operating system which handles data flow in the control layer. Generic commands from the user station causes the operating system to call specific subroutines the produce digital commands. These digital commands are then passed to a digital layer that interfaces with an analog layer. The analog layer is specifically developed to interface and work with a specific optical device. The analog layer thus directly controls the optical device including changing its settings based on input from the digital layer.

  • Patent number: 6823223
    Abstract: A method and apparatus for providing a simple user interface for programming scenes and multi-way groups in a home automation and control system is provided. Each device participating in the home automation and control system is equipped with control logic for providing the simple programming interface. Through the control logic, each device maintains its status in a system-wide programming mode and retains knowledge of its inclusion or exclusion in the current scene or multi-way group being programmed. When any device in the system receives indications that affect the system programming mode, such as a press on one of the buttons on the devices, the device broadcasts a notification message to all devices within the home automation and control system. The message maintains the integrity of the system programming mode. Each device knows when a scene or multi-way group being programmed is finally captured and the programming of a new scene or multi-way group has started.

  • Publication number: 20040181294
    Abstract: A configuration system for a process plant includes a routine that automatically provides an indication of the relationships between units and sub-elements of the units, such as equipment and control modules, present within a process plant to a data historian. The data historian, which may be a batch historian, stores these relationships in a configuration file or a database, collects events generated within the process plant and associates those events to the proper unit within the process plant using the stored relationships. The automatic updating of the data historian configuration file eliminates the need for a user to manually update the data historian with these relationships, either at the time the process plant is configured or each time a change is made to the configuration of the process plant.
