Abstract: An optical reader is suitable for reading 2-dimensional indicia. The optical reading device, that may include a bar code reader, comprises a guide whose length along the optical reader optical axis is such that when that guide contacts the part or equipment surrounding the indicia to be read, that indicia is within the optical reader depth of field. The reader comprises a housing having therein a source of illumination and optics for producing a diverging beam for illuminating indica. A spacing element transparent guide is removably attached to the housing, and does not block indicia. The line of contact of the guide with the data carrier is substantially fully visible to the operator, who can thus confirm that the guide is in proper operating position relative to the indica prior to initiating a reading operation. A reading operation can be initiated by pressing on the guide to actuate a switch, or on a manual trigger.

The elements are independent and identical to one another so that conventional array beamforming techniques may be utilized.

Abstract: The present invention is a current sensing method and apparatus wherein a current transformer producing a secondary current is disposed in communication with a conductor having a primary current desired to be sensed. A current analyzer in communication with the current transformer is adapted to estimate the primary current in the conductor based on the secondary current output waveform, even in the case where the secondary current is in saturation. In one embodiment, the current analyzer estimates the primary current in the conductor by capturing the secondary current waveform output from the current transformer, selecting a predetermined number of data points in an undistorted, region of the secondary current waveform, and estimating the primary current based on the selected data points.
