An automated computer-implemented method for generating commands for controlling a computer numerically controlled machine to fabricate an object from a workpiece, the method including the steps of selecting a maximum permitted engagement angle between a rotating cutting tool and the workpiece, selecting a minimum permitted engagement angle between the rotating cutting tool and the workpiece, and configuring a tool path for the tool relative to the workpiece in which the engagement angle gradually varies between the maximum permitted engagement angle and the minimum permitted engagement angle.

Techniques for commissioning a process control device in a process plant include obtaining, at a portable computing device, commissioning data for commissioning the respective process control device for operation, such as a device tag. The portable computing device then transfers the commissioning data to a component in the same process control loop as the process control device via a wireless communication link. For example, the component includes a radio-frequency identification (RFID) or near field communication (NFC) unit for receiving RFID/NFC signals. When the portable computing device is within RFID/NFC communication range of the component, the commissioning data is transferred via an RFID/NFC signal to the component. The commissioning data is received while the component is in an unpowered state, where the RFID/NFC signal energizes the RFID/NFC unit at the component for receiving the signal.

A solid-state switch, comprising at least one switch controller. At least one switch having a first terminal coupled to a power source, a second terminal coupled to the power source and a control terminal coupled to the switch controller and configured to selectively conduct and block current flow from the first terminal to the second terminal. At least one power converter coupled to the first terminal and the second terminal and configured to convert power from the power source from a first voltage level to a second voltage level and to provide power at the second voltage level to the switch controller.

A method for monitoring a condenser pressure protection curve with a polygon function of a turbine using an SPS safety monitoring system, includes reading a first measurement value and a second measurement value, standardizing the second measurement value to a value scale of the first measurement value using a standardizing module of the SPS safety monitoring system, comparing the first measurement value with the standardized second measurement value using a comparison module of the SPS safety monitoring system, and generating an output signal in response to the standardized second measurement value exceeding the first measurement value.

An apparatus for a heart of a patient having a cardiac assist device adapted to be implanted into the patient to assist the heart with pumping blood. The apparatus has a sensor adapted to be implanted into the patient. The sensor in communication with the cardiac assist device and the heart which measures native volume of the heart. Alternatively, the sensor monitors the heart based on admittance while the cardiac assist device. Alternatively, the sensor monitors the heart based on impedance.

A portable handheld device pairs with a first building control device, to form a first wireless connection. The portable handheld device receives information about a second building control device via the first wireless connection, at least some of the information is received by the first building control device from the second building control device over a building control network before the first building control device provides at least some of the received information to the portable handheld device via the first wireless connection. The portable handheld device sends one or more messages to the first building control device via the first wireless connection, wherein the one or more messages cause the first building control device to communicate with the second building control device via the building control network to initiate a commissioning and/or maintenance process of the second building control device.

Programmable controller technology, in which data is received that identifies a particular type of HVAC system component that is to be controlled by a programmable controller. Based on receiving data identifying the particular type of HVAC system component, configuration information is accessed for the particular type of HVAC system component. A configuration is determined for one or more interface ports of the programmable controller based on the configuration information for the particular type of HVAC system component. The interface ports of the programmable controller are configured according to the determined configuration. A connection between the particular type of HVAC system component and the programmable controller that satisfies the determined configuration is detected. Based on detecting the connection between the particular type of HVAC system component and the programmable controller that satisfies the determined configuration, the particular type of HVAC system component is controlled through the one or more interface ports.
