Abstract: Hub-based electronic lock systems and devices relate to lock or access control systems, and more particularly to electronically controlled lock systems such as may be applied to various storage enclosures or cabinets to provide secure storage of various items, equipment, materials, and/or information within the enclosures or cabinets. Certain present aspects may relate to hub and/or daisy-chained control for a plurality of electronic locks used in an electronic access control system, for inventory management using electronic locks, and/or to electronic locks with various features including display screens, access controls and tracking, and alert capabilities.

Abstract: Disclosed are apparatus and corresponding methodologies for data control in an electronic access control system. A plurality of electronic locks are connected to a central server over a network such as an 802.11 WiFi wireless network that may be used to provide data updates and management for the individual electronic locks. To address power management problems associated with electronic locks having the capability to communicate over an 802.11 WiFi network, the present disclosure provides method and apparatus for selectively powering on and off an 802.11 WiFi communications module integrated into the electronic lock to conserve power resources. An electronic access control system is disclosed which allows efficient data exchange between a central server and a plurality of electronic locks using a database structure, and which allows for multiple simultaneous database manipulations in a cost effective manner.

Abstract: Apparatus and methodology for providing electronic access control are disclosed. In an exemplary configuration, a retrofittable electronic lock can be used to provide secure storage to an enclosure. A user interface and LCD visual display can be provided to permit convenient adjustment of system operational parameters. In certain embodiments, the electronic access control system includes master-slave control capabilities. In other embodiments, the electronic access control system includes inventory management capability. In still other embodiments, apparatus and methodologies provide the secure storage of the enclosure when the enclosure is being moved or otherwise transported from one location to another location. Various alternative arrangements may provide various alert features, as well as battery features which facilitate rapid replacement and/or reconfiguration.

Abstract: An apparatus and a method for use with an electronic locking system is provided. At least one key is selected in order to have access to at least one lock. This key to lock relationship is transferred to a memory of the key. The key is presented to the lock and at least a portion of the key to lock relationship from the key is transferred to a memory of the lock. This transfer updates the memory of the key to lock relationships in the lock. The update of the memory in the lock is noted in the memory of the key. The key may then be placed in communication with a computer so that at least a portion of the memory of the key is transferred to a database in the computer. This transfer updates the database in order to reflect the fact that the memory of the lock has been updated and completed.

Abstract: A floor care machine such as a burnisher may operate in a manual or automatic mode for controlling the operating pressure of the working unit, such as a brush or pad. The illustrated machine has a motor and pad driver assembly mounted for height adjustment by an actuator. In the automatic mode, a transducer senses motor current (i.e., load) and generates a signal representative of the actual operating pressure exerted by the pad on the floor. A microprocessor-based controller controls the actuator to adjust the height of the pad relative to the floor, and thus adjusts the pad pressure on the floor, according to a setting selected by the operator. The controller is programmed to reduce the effect of "hunting" by entering a Lock Mode after operation has achieved predetermined conditions. System operation remains in the Lock Mode as long as other criteria are met, and operation returns to a Hunt Mode if these other criteria are not met.
