A communication apparatus is provided that can urge a person who is not at home such as, for example, a child to come back home when scheduled coming home time comes and can inform a notification of the time at which the child comes home, for example, to the parent. The communication apparatus includes first communication means which communicates with an electronic key device in which at least electronic key information is stored, and door lock control means which compares the electronic key information received and electronic key information stored in a storage section with each other and controls a lock apparatus for a door based on the result of the comparison. The communication apparatus further includes user recognition means which recognizes a user of the electronic key device based on the information received from the electronic key device through the first communication means. Sender control means controls based on the result of the recognition by the user recognition means so that information regarding passing in / out of the user of the electronic key device is transmitted to a notification destination determined in advance through second communication means.

A padlock for luggage that can be operated by setting a combination or by inserting and turning a key is provided with an indicator that normally displays a first state when the lock being used in a normal way as a combination operated padlock, but which displays a second state if the padlock has been opened by utilizing a key.

A monitoring method includes detecting instances of physical presence of at least one individual, storing location information identifying the at least one individual and information related to the instances, displaying on a display a visual image of a physical environment and displaying on the display an image depicting the at least one individual's movements through the physical environment based on the stored location information.

A padlock includes a housing, a shackle, a number lock mechanism, a key lock mechanism, a movable block, and an identification member. Thus, the identification member is exposed outward from the window of the limit knob after the padlock has been unlocked by an inspector of the customs for checking the luggage so as to remind a user to inspect if contents of the luggage that has been opened and checked are missed or lost.

A multipurpose seal with a lock, including a mobile closure apparatus of a casing containing a lock and an attachment element designed to be locked in the casing. The lock includes a barrel configured to move in the casing between a locked position and an unlocked position. A remote-interrogatable electronic component including a data-storage is maintained in a housing, which passes through part of the casing and part of the lock barrel when the lock barrel is in the locked position. Thus, any rotation of the barrel from the locked position causes the component to break.

An electronic key may include a partial capacitor comprising a capacitive metal plate in communication with a processor. The capacitive metal plate of the partial capacitor is configured to form a capacitor with a corresponding capacitive metal plate of a lock when brought into proximity with the metal plate of the lock. Data may be transferred from the key to the lock using a capacitor formed by combining the two metal plates, wherein a common ground is established between the metal plate of the key and the metal plate of the lock through a parasitic capacitance present between the key and lock circuitry.

A communication apparatus is provided that can urge a person, such as a child, to come back home at a scheduled time. The communication apparatus can also inform another person, such as a parent of the child, about the time that the child arrives home.

A lock includes a casing, an indicator movably received in the casing between a first position and a second position and a core received in the casing and so configured in such a way that a private key and a general key are able to activate the core. The movement of the indicator from the first position to the second position is in response to a status where the general key is applied to activate the core.

A collective housing shared entrance device, a collective housing door-to-door interphone device, a door-to-door containing box management device, and a communication system capable of controlling access and call of a visiting trader and passing and receiving an article door-to-door. An IC card is distributed to inhabitants and traders who are allowed to enter (registered traders). By using the IC card, inhabitant identification information and trader identification information are transmitted to the shared entrance device (2). If an inhabitant of the collective housing or a registered trader who has been registered in advance is identified, the person is allowed to enter the collective housing. At each door, family identification information and trader identification information are transmitted from the IC card to the interphone device (4). If a family member is identified, the door lock is released. Moreover, depending on whether the person is a registered trader or the other traders, the calling sound is changed or call sound is sent out / not sent out. Moreover, traders set among the registered traders are allowed to utilize door-to-door containing boxes.
