| 20140311197 | DOOR LOCK INDICATOR - A door lock indicator and method for use by occupants in an interior space to confirm if a lock of a door handle of a door is in a locked or an unlocked position. An inside handle of the door handle must always be free to open the door for immediate exit. When a locking mechanism is in a first position, the locking mechanism aligns with an indicator mechanism to provide an indication that the door handle is in the unlocked position. When the locking mechanism is in a second position, the locking mechanism does not align with the indicator mechanism to provide an indication that the door handle is the locked position. | 10-23-2014 |

| 20130233035 | TAMPER EVIDENT CARGO CONTAINER SEAL BOLT LOCK - Systems and methods for a tamper-evident cargo container seal bolt lock are disclosed herein. The device can include a bolt member having a conductive medium running the axial length of the bolt, and a receiving member for locking the bolt into place. A battery-driven sensory circuit including a memory means, a processor, and a timing circuit can be disposed within the receiving member such that a continuous circuit is formed from one circuit pin over the conductive medium through the length of the bolt and back to a second pin. The sensory circuit is configured to sense whether the circuit has been interrupted (e.g., if the bolt has been cut). In the event of an interruption, the circuit can record the time and/or date in memory. This information can then be transmitted to an RFID reader/interrogator if a dispute arises as to when the lock had been broken. | 09-12-2013 |
| 20130255337 | TAMPER EVIDENT CARGO CONTAINER SEAL BOLT LOCK - Systems and methods for a tamper-evident cargo container seal bolt lock are disclosed herein. The device can include a receiving member, a conductive bolt member adapted to be snap-locked into the receiving member, and a plastic encapsulant which tethers the bolt member to the receiving member. The encapsulant can contain an electrically conductive medium, such as a wire, which runs from the receiving member to the second end the bolt. A sensory circuit disposed within the receiving member can be configured to sense whether the circuit has been interrupted (e.g., if the bolt has been cut). In the event of an interruption, the circuit can record the present time and/or date in memory. An RFID transponder disposed within the encapsulant or the receiving member can then transmit the recorded date/time to an RFID interrogator if a dispute subsequently arises as to when the lock had been broken. | 10-03-2013 |

| 20080295555 | Locking Seal With Tamper Indication And Notification Device - A locking device comprising a lock body having a through hole, a bolt member having a longitudinal bore therethrough and an insertion end which is inserted into the through hole of the lock body. The bolt member is further having a retaining pin disposed within the longitudinal bore and a resilient means for biasing the retaining pin axially out of the longitudinal bore. When the bolt member is inserted into the lock body, a means within the lock body prevents the removal of the inserted bolt member therefrom, and engages an actuating means to actuate an identifying means. The identifying means transmits a signal to indicate whether the locking device has been tampered with or defeated. If the bolt member is cut, the retaining pin is displaced out of the longitudinal bore and dislodges the actuating means resulting in the identifying means indicating that the locking device has been tampered with or defeated. | 12-04-2008 |
