Optical character recognition in which registration of a stored, character image is changed from, for example, center to lower left depending on the individual character template or equivalent description against which the image is being compared. Accuracy is improved because the registration form used is one known to provide the greatest elements distinguishing the character of the template from the closest other character which might be presented.

An electronic combination lock is provided with and incorporates the enhanced feature of covert entry detection and notification. Whenever the bolt of an electronic lock provided with this enhancement is retracted to its withdrawn or unlocked position and whenever the lock has not received an authorized combination enabling the movement of the bolt, movement of the bolt is detected and the electronics of the lock is powered for a time sufficient to record an indication of the covert entry in its non-volatile memory. Upon normal operation at a subsequent time, the indication of covert entry is read from the non-volatile memory and a visual indication is displayed to the operator to inform the operator that covert entry has occurred. The lock may be configured either to permit the lock to open with an authorized combination after display of the covert entry indication to the operator; or alternatively, the lock may be configured to be disabled as a result of the detection of a covert entry such that the lock will refuse to accept all authorized combinations until such time as the lock has been reset or reconditioned to remove the covert entry indications stored in the memory.

To prevent the opening of an electronic combination lock by using a strong magnet to operate a stepper motor, a magnetic interlock is included in the lock structure. A magnetic pin is held in a retracted position by a small magnet when a strong attack magnet is positioned to attempt to open the lock, the magnetic pin is attracted from the holding magnet and extended to bridge the bolt and lock housing, blocking the retraction of the bolt.

The invention concerns a system of English language abstracting used to increase the search rate for an Index Search machine that, as an example makes use of magnetic record cards each having in a typical case 50 tracks for recording of information. To increase the rate at which groups of words can be compared, an abstract of each group of words is generated. On the magnetic card the text or groups of words are recorded on tracks 2 through 50 and the abstracts of these groups are recorded in track 1. When searching for a particular group of words, an abstract is generated for the group being sought. This abstract is then compared to the abstracts on track 1 of each card. If any of the abstracts match, the corresponding group of words on the card are searched in detail. For abstracts that do not match there is no need to search the corresponding group of words. Therefore, the need to search every group of words is eliminated, thus increasing the search rate.
