A library terminal permits a user to execute a loan transaction without assistance. The library terminal (i) provides a visible scan line from a bar code reader indicating the correct positioning of the bar code on a circulating item, (ii) leads a user through a loan transaction, (iii) provides an explicit feedback to a user when an article has an improper position on the article receiving area, (iv) both checks out and checks in circulating items, (v) stores fonts in bit maps of screen displays instead of in a separate font memory, (vi) integrates a security marker reader, a printer, and a controller in the same housing, (vii) processes financial transaction related to the borrowing of circulating items, and/or (viii) displays actions for helping the user to correct errors in use of the terminal.

An antenna lattice for use in a magnetically based electronic article surveillance system. The lattice includes a field-producing coil assembly which includes a pair of trapezoidal-shaped segments, each having a diagonally extending lower portion, the segments being juxtaposed in a mirror image so that the diagonal portions are opposite each other. The segments are connected so that vertical components of the currents in the diagonal sections at least partially cancel. Preferably, top horizontal sections of each segment are located at different levels, thereby extending the upper coverage, and a detector coil preferably also juxtaposed extends above the top horizontal section of the field-producing coil to further extend the range of detection.

An electronic article surveillance (EAS) systems includes an asynchronous noise suppression adaptive filter which removes asynchronous interference from the signal of interest with minimum distortion of the transients emitted when a sensitized tag is interrogated. The system also includes a synchronous noise suppression filter which removes interrogation synchronous noise from the signal of interest. The resulting EAS system increases the likelihood that a sensitized tag will be detected when one is present and reduces the occurrence of false alarms.

The terminals of a device under test are temporarily electrically connected to corresponding contact pads on a load board by a series of electrically conductive pin pairs. The pin pairs are held in place by an interposer membrane that includes a top contact plate facing the device under test, a bottom contact plate facing the load board, and a vertically resilient, non-conductive member between the top and bottom contact plates. Each pin pair includes a top and bottom pin, which extend beyond the top and bottom contact plates, respectively, toward the device under test and the load board, respectively. The top and bottom pins contact each other at an interface that is inclined with respect to the membrane surface normal. When compressed longitudinally, the pins translate toward each other by sliding along the interface.
