A multi-functional personal security device includes a housing for wear by a user. The housing contains a position module, a communications module, a smart switch, and first, second, and third security modules. The position module determines a geo-position of the housing. The communications module detects a cellular device. The security modules individually respond to activation of the smart switch to provide respective security functions. Switch activation occurs in response to a pressing sequence of a button and/or voice commands, which may activate the first security function only when the cellular device is present. Activation of the smart switch in response to a second input sequence activates the second and third security functions, e.g., a strobe and audible alarm. Panic, Silent Panic, Countdown, and Tracking Modes may be selectively enabled.

An example method may include monitoring at least one tag enabled device, identifying a condition exists which requires a notification, notifying at least one registered device of the condition, responsive to a predetermined period of time lapsing, creating an emergency condition and notifying an emergency service provider.

Implementations of a child safety system is provided. Implementations of a child safety system comprises portable transmitter configured to transmits a wireless signal compatible with Bluetooth technology and a portable computing device configured to receive the wireless signal and compute a distance between the portable computing device and the transmitter based on the signal strength of the wireless signal received. The portable computing device further is configured to sound an alarm on the portable computing device once the distance between the portable computing device and the portable transmitter equals or exceeds a preset distance.

An anti-theft proximity alert system that includes a wearable smart charm with a charm housing, and an object monitor with a housing and a snooze switch, and a controller with at least one snooze operating instruction to adjust a threshold alert criterion based upon a setting of said snooze switch.

A vehicle-mountable child protective device including a housing which is mountable onto a door of a vehicle and including a first housing portion, which is at least partially located within the vehicle when the device is mounted onto the vehicle and during device operation, and a second housing portion, which is at least partially located outside the vehicle when the device is mounted onto the vehicle and during device operation, a flag which is rotatably mounted via a flagpole onto the first housing portion and a flag positioning assembly at least partially within the first housing portion for automatically rotating the flag to a raised position outside of and above the vehicle upon opening of the door of the vehicle.

A control device includes an interface module configured to supply electric power to a field device installed in a plant, an application executer configured to output a reset signal for resetting the field device, and a converter configured to convert the reset signal, which has been output from the application executer, into a format which is suitable for the interface module.

The watching system includes: an action detection unit capable of detecting a plurality of types of actions of a care recipient a storage unit for storing notification interval information specifying a notification interval for each combination of actions; a determination unit for determining, when the action detection unit detects that the care recipient takes a first action targeted for notification and, following the first action, detects that the care recipient takes a second action targeted for notification, a notification interval from notification intervals specified in the notification interval information, that is associated with a combination of the first action and the second action; and a notification control unit for suppressing notification of the second action when a detection interval from the detection of the first action to the detection of the second action is shorter than the notification interval determined by the determination unit.

A mobile signal unit is responsive to a mobile operating unit yet sufficiently compact and lightweight for unobtrusive connection to an item of clothing, a purse, and/or a backpack. It has a siren powered by gas or electricity. It has a wireless first interface, through which the siren can be remotely activated and/or deactivated by the mobile operating unit. The siren can be activated manually by an activation command that matches an activation code stored in a memory unit of the signal unit and/or the operating unit. The siren is automatically activated after the wireless connection to the operating unit if a connection signal strength of the operating unit falls below a threshold and/or the wireless connection to the operating unit is interrupted.

A physical wallet separation alert system capable of detecting, alerting, and defining a potentially-dangerous separation between a physical wallet and a mobile communication device is disclosed. In one example, the potentially-dangerous separation involves a user-defined excessive separation (e.g. a few meters, ten meters, twenty meters, etc.) between the physical wallet and the mobile communication device that may suggest a potential loss or theft of the physical wallet or the mobile communication device during a real-time tracking of the separated distance by a wallet separation prevention application executed by the mobile communication device. A physical wallet separation alert may be visual, aural, textual, or a combination thereof. The physical wallet separation alert system is capable of simultaneously tracking multiple physical wallets that are registered with the system. Furthermore, each registered physical wallet integrates a wireless tag configured to be accessed by an RFID reader incorporated into the mobile communication device.

An anti-theft proximity alert system that includes a wearable smart charm with a charm housing, and an object monitor with a housing, an environmental sensor to detect an ambient environmental condition, and a controller with at least one environmental operating instruction to adjust the output of a sensory alert based upon detected environmental conditions.
