Abstract: A network processor or other type of processor includes a packet analyzer and first memory circuitry operatively coupled to the packet analyzer. The packet analyzer is operative to at least partially analyze one or more packets received by the processor in order to determine for a given one of the packets a portion of the packet to be stored in the first memory circuitry. The portion of the given packet when stored in the first memory circuitry is thereby made accessible for subsequent processing within the processor, without requiring access to second memory circuitry associated with the processor and configured to store substantially the entire given packet. The packet analyzer may be configured to utilize a value stored in a register of the processor to determine the portion of the given packet to be stored in the first memory circuitry. The register may be one of a number of registers which implement a look-up table accessible to the packet analyzer.

Abstract: A method and apparatus for calibrating a welding-type power supply and a robot are disclosed. They include entering a calibration mode (in the welding-type power supply) and providing one or two predetermined commands (for a welding parameter) from the robot to the welding-type power supply, and comparing them to two standards. A command scaling curve for the parameter is calculated in response to the comparisons. Predetermined commands, relating to two or more different welding parameters, may be used to calibrate two or more parameters, and to create two or more command scaling curves. Parameters that are calibrated include wire feed speed, voltage and arc length (trim). Feedback from the welding-type power supply may be provided to the robot that is indicative of a commanded output. The predetermined commands may alternatively be user-determined, or provided by a user interface or a memory.

Abstract: A small sized electro-optic voltage sensor capable of accurate measurement of high levels of voltages without contact with a conductor or voltage source is provided. When placed in the presence of an electric field, the sensor receives an input beam of electromagnetic radiation into the sensor. A polarization beam displacer serves as a filter to separate the input beam into two beams with orthogonal linear polarizations. The beam displacer is oriented in such a way as to rotate the linearly polarized beams such that they enter a Pockels crystal having at a preferred angle of 45 degrees. The beam displacer is therefore capable of causing a linearly polarized beam to impinge a crystal at a desired angle independent of temperature. The Pockels electro-optic effect induces a differential phase shift on the major and minor axes of the input beam as it travels through the Pockels crystal, which causes the input beam to be elliptically polarized.

Abstract: The invention is a miniature electro-optic voltage sensor system capable of accurate operation at high voltages without use of the dedicated voltage dividing hardware typically found in the prior art. The invention achieves voltage measurement without significant error contributions from neighboring conductors or environmental perturbations. The invention employs a transmitter, a sensor, a detector, and a signal processor. The transmitter produces a beam of electromagnetic radiation which is routed into the sensor. Within the sensor the beam undergoes the Pockels electro-optic effect. The electro-optic effect produces a modulation of the beam's polarization, which is in turn converted to a pair of independent conversely-amplitude-modulated signals, from which the voltage of the E-field is determined by the signal processor. The use of converse AM signals enables the signal processor to better distinguish signal from noise.

Abstract: A miniature electro-optic voltage sensor and system capable of accurate operation at high voltages has a sensor body disposed in an E-field. The body receives a source beam of electromagnetic radiation. A polarization beam displacer separates the source light beam into two beams with orthogonal linear polarizations. A wave plate rotates the linear polarization to rotated polarization. A transducer utilizes Pockels electro-optic effect and induces a differential phase shift on the major and minor axes of the rotated polarization in response to the E-field. A prism redirects the beam back through the transducer, wave plate, and polarization beam displacer. The prism also converts the rotated polarization to circular or elliptical polarization. The wave plate rotates the major and minor axes of the circular or elliptical polarization to linear polarization. The polarization beam displacer separates the beam into two beams of orthogonal linear polarization representing the major and minor axes.

Abstract: A plastic mounting plate closes a junction box which delivers wires to an alarm unit or emergency light or the like. The mounting plate is connected to the junction box by screws which engage threaded holes provided by the junction box. The mounting plate can be mounted to either a single-wide junction box or a double-wide junction box and provides corresponding holes for connection to either box. An alternate mounting plate for a single-wide junction box is also provided. An alarm device can be connected to the mounting plate directly by screws or by a combination of a single screw and a tab which is received into a slot onto the mounting plate. The mounting plate can be color-coded for a particular alarm service, such as fire, weather warnings, or other emergency condition.
