Abstract:
A system may include a first security component configured to emanate a signal with an authorizing code, and may have a magnetic field generating device configured to generate a signaling magnetic field including the signal with the authorizing code. The system may also include a second security component configured to wirelessly receive the signal with the authoring code when the second security component is proximate to the signaling magnetic field of the first security component. The second security component may include a magnetic field sensor configured to sense the signal emanating from the magnetic field generating device, and the sensor may be changed between first and second states by a change in the signaling magnetic field.
Abstract:
A system for notifying occupants of a structure that a pet is proximate to an opening of a structure. The system may include a pet unit wearable on the pet's body and including a transmitter configured to transmit a wireless proximity signal from the pet unit. The system may further include an exit unit positionable at an exit of the structure. The exit unit may include a receiver configured to receive a said wireless proximity signal transmitted by a pet unit, with the receiver being configured to produce an alert signal when a said wireless proximity signal is received. The exit unit my also include an alerting assembly configured to provide a presence alert when the receiver receives a said wireless proximity signal. T alerting assembly may comprise a perceptible alerting mechanism configured to produce a perceptible presence alert which is perceptible to a sense of a human.
Abstract:
A system may include a container security apparatus for monitoring and communicating status information regarding a protected space in an interior of a container. The security apparatus may include a casing, a sensor assembly associated with the casing including at least one sensor configured to sense at least one condition in the interior of the container, a controller configured to receive sensor information from the sensor assembly and record the sensor information, and a communication assembly configured to communicate information from the controller including the sensor information.
Abstract:
A text rendered using a first font in a first region of a display, and the text rendered using a second font in a second region of the display, are displayed simultaneously on a webpage. An option to manipulate the text rendered using the first font and the text rendered using the second font is provided. In response to a selection of the option, the text rendered using the first font and the text rendered using the second font are manipulated. A code associated with a style sheet corresponding to a selected one of the first font and the second font is generated.
Abstract:
A system may include a lock assembly having a shell and a plug rotatable with respect to the shell and a lock operating object for operating the lock assembly including a key. The system may further include an audit enhancement assembly configured to facilitate creation of an audit trail of operation of the lock assembly by the lock operating object, and may include a motion sensor configured to sense rotational motion of the lock operating object and/or the plug of the lock assembly. The audit enhancement assembly may include processing circuitry in communication with the motion sensor, and memory circuitry in communication with the processing circuitry to receive and record a value derived from a motion signal from the motion sensor and a temporal value associated with a motion signal event.
Abstract:
A deadbolt lock status sensing assembly for monitoring status of a deadbolt member of a deadbolt assembly on a door may include a sensible element mountable on one of the door and the deadbolt assembly, and a sensing element mountable on one of the door and the deadbolt assembly. The sensing element and the sensing element may be configured to move with respect to each other when the deadbolt member of the deadbolt assembly moves between an extended condition and a retracted condition of the deadbolt.

Abstract:
A lock assembly (10) including a plug (12) having a keyway (14) for inserting therein a key (16), and a movable element (18) movingly disposed in the plug (12), the movable element (18) being divided into at least two separate magnetic portions (20, 22) arranged to move relative to one another and having identical magnetic polarity, wherein the magnetic portions (20, 22) are sufficiently near one another such that one of the magnetic portions (20, 22) applies a magnetic repelling force on the other magnetic portion (20, 22).

Abstract:
A pin tumbler lock of a first embodiment includes a shell containing top pins; and a plug, rotatable within the shell, containing standard bottom pins, and a shorter bottom pin, set back from the face of the plug. A tubular key has bitings corresponding to the standard bottom pins, and a projection corresponding to the short bottom pin. When the key is inserted, the bitings and the projection press all the bottom pins to the shear line. In a second embodiment, a lock includes a shell containing top pins and a depression; and a plug, rotatable within the shell, containing bottom pins. The depression is configured and dimensioned to receive one of the bottom pins. The depression may be opposite one of the bottom pins, and there may be one more bottom pin than top pins. When the key is inserted, the bottom pins are moved to the shear line.
