Title: System and method for refining search queries
Inventor: HAMRICK MICHAEL L
IPC: G06F17/30
Filed: 1999-06-11
Granted: 2007-03-27
Abstract: A search engine is disclosed which suggests related terms to the user to all ow the user to refine a search. The related terms are generated using query term correlation data which reflects the frequencies with which specific terms have previously appeared within the same query. The correlation data is generated and stored in a look-up table (137) using an off-line process (136) which parses a query log file (135). The table (137) is regenerated periodically from the most recent query submissions (e.g., the last two weeks of query submissions), and thus strongly reflects the current preferences of users. Each related term is presented to the user via a respective hyperlink (910) which can be selected by the user to submit a modified query. In one embodiment, the related terms are added to and selected from the table (137) so as to guarantee that the modified queries will not produc e a NULL query result.

Abstract: An apparatus and method for automatically identifying faults in the operation of a machine vision measuring systems provides an improved self-diagnostic capability for machine vision based metrology and tracking systems. The method and apparatus validate performance of tracking operations, and detect deterioration that may be caused by electronic noise, environmental contamination, etc. A mathematical model of the target visualized by the system is created and stored. A target is imaged in the field and fiducials of the target are identified. Centroid positions of detected fiducials of the imaged target are compared to the centroid positions of fiducials in the mathematical model. When a fiducial is obscured or dirty, its geometric characteristics (such as centroid, brightness, edge smoothness, area, or shape) differ from the true or idealized values of the characteristics. Values representing detected fiducials are discarded when the offset exceeds predetermined criteria, or when its properties vary from ideal. If the remaining number of detected fiducials is below a predetermined threshold, a warning message is displayed or an error is generated. Thus, when a fault is detected that degrades performance beyond a preset tolerance, the fault is flagged for attention and a suggested corrective action is displayed.

Abstract: A security alarm system that may be selectively armed or disarmed when monitoring a protected premises is described which utilizes the position of a deadbolt to determine whether the security system should be armed or disarmed. The security system comprises (i) an entry door for permitting ingress to the protected premises from the outside of the entry door and egress from the protected premises from the inside of the entry door; (ii) a lock for selectively locking and unlocking the entry door; and (iii) a switch having a first state indicative of the lock being in a locked position and a second state indicative of the lock being in an unlocked position wherein, when the switch is in its first state, the security system is armed and, when the switch is in its second state, the security system is disarmed. Sensing means are also provided to determine if the lock was engaged from inside or outside the protected premises. In the case where the lock was engaged from outside the premises and no authorized individual remains inside, sensors inside the premises would become activated. Conversely, in the case where the lock was engaged from inside the premises or from outside the premises and an authorized individual remains inside, the inside sensors would remain deactivated. The disabling of an inadvertent (false) alarm is easily, yet securely, achieved by activating a first user-controlled disarming means and returning the lock to its unlocked position.
