A method for determining a battery status of a battery in a portable electronic device includes storing a baseline cycle count in memory of the portable electronic device, the baseline cycle count value being an empirically determined number of actuations that results in a requisite amount of battery depletion to achieve a low battery condition; determining an actual cycle count corresponding to an actual number of actuations of the portable electronic device; comparing the actual cycle count to the baseline cycle count to determine whether the low battery condition exists; and if the low battery condition exists, then notifying a user of the low battery condition.

A spring force indicator for a door closure having a spring force spring force adjuster comprises a drive wheel coupled to the spring force adjuster for rotation therewith and a driven wheel. The driven wheel includes a disc and a post extending from the disc, the post being disposed in a bore formed in a front surface of the door closure and adapted to engage the drive wheel for rotation therewith. The disc further includes first indicia. A cover includes a base wall and a cylindrical sidewall depending from the base wall, the cover being disposed on the end of the door closure and configured to cover the drive wheel and the driven wheel. The cover includes a central aperture for receiving the spring force spring force adjuster, a second aperture disposed between the central aperture and the sidewall, and second indicia disposed around the second aperture. The first indicia is visible through the second aperture, and the first indicia cooperates with the second indicia to indicate a measure of spring force.

A latchbolt assembly includes a solid latchbolt having at least a first surface, a second surface and a third surface and an anti-friction bolt pivotally coupled to the solid latchbolt. The anti-friction bolt includes a cross member disposed adjacent the first surface of the solid latchbolt and a pair of plates depending from the cross member to form a U-shaped cross section. The plates are disposed adjacent the second and third surfaces of the solid latchbolt.

The ability to open and close architectural closures, such as doors and windows, is often controlled to prevent unauthorized entry into buildings or rooms or to aid in opening and closing the closure. The position of architectural closures may also be monitored to determine if the closure has been opened. According to an exemplary embodiment of the present disclosure, a closure position detector is provided for use with an architectural opening having a perimeter and a closure having an outer perimeter and moveable between an open position and a closed position closing the opening. The closure position detector includes an electronic device.

Abstract
A mortise lock includes a mortise lock case, a bolt that extends and retracts relative to the mortise lock case, and a lock core that extends and retracts the bolt. The lock core includes a lug positioned within the mortise lock case that prevents withdrawal of the lock core from the mortise lock case.
A wireless security system is provided that includes a plurality of wireless locks positionable to control access through a plurality of doors, a plurality of communicators configured to wirelessly communicate with the plurality of wireless locks, and a central host including a database of credential information. The plurality of wireless locks include a database of credential information regarding credentials that are authorized to allow access through the plurality of doors. The plurality of wireless locks periodically initiate requests for updated credential information. The plurality of communicators provide the updated credential information to the plurality of wireless locks in response to request for updated credential information from the plurality of wireless locks. The central host is configured to receive updated credential information and to communicate the updated credential information to the plurality of communicators.
A lock assembly (16) for securing a container (10) having an interior region is disclosed. The lock assembly (16) includes a housing (18) positionable on the interior of the container (10), a bolt (26) moveable relative to the housing (18) between an extended position inhibiting access to the interior region of the container (10) and a retracted position to facilitate access to the interior region, a dial (20) positionable on an exterior of the container (10). The dial (20) includes a plurality of indicators (30, 32) indicative of a plurality of dial positions, and an electronic controller (46) operably coupled to the dial (20) to detect the relative position of the dial (20) to determine if a combination entered with the dial (20) provides authorization to move the bolt (26) from the extended position to the retracted position.
A lock assembly (30, 30') is provided that includes a housing (32), a rotary bolt (36) or a translating bolt (36'), and a bolt blocker (38) that moves between a blocking position blocking movement of the bolts (36, 36') and an unblocking position permitting the bolts (36, 36') to move to a retracted position. The lock assemblies (30, 30') are resistant to shocks being applied to the locks assemblies (30, 30') in an effort to open the lock assemblies (30, 30') without authorization.
A lock core (10) and key blank (12) are disclosed. The disclosed lock core (10) includes a core body (26), a core sleeve (28), a core plug (30), and a side pin assembly including a side pin (34), a region pin (36), and a spring (38).
