摘要： A method of estimating a characteristic of a formation includes: disposing a radar imaging tool in a borehole; generating a high frequency radar signal by a radar transmitter, the high frequency radar signal having a frequency configured to limit penetration of the radar signal to a near-borehole region of the formation, the near-borehole region including a surface of the borehole and a region of the borehole proximate to the surface; detecting return signals reflected from the near-borehole region; generating an image of the near-borehole region based on the return signals; and estimating a characteristic of the formation based on the image.

摘要： A method of controlling operation of a print head to align imprints printed by the print head in two traverses in opposite directions is disclosed. The print head includes a row of printing elements that are operated selectively in a plurality of print cycles to print each imprint. Upon completion of printing a first imprint, signals corresponding to motion of the print head step the count of a counter. The stepping of the counter is terminated when the print head passes a reference position. During a reverse traverse of the print head, stepping of the counter is initiated when the print passes the reference position and operation of the print head to print a second imprint is initiated when the count reaches a predetermined count.

摘要： In a device 1 which uses consumable material, an electronic device 24 is attached to the packaging 20 of the consumable which stores information about the consumable, and the quantity remaining in the packaging. The device is thus capable of reading such information and updating it by decrementing a counter of the electronic device 24 and optionally responding accordingly, i.e. if the wrong type of consumable is used.
