A security device for an electrically powered device includes a remote location-tracking circuit for mounting in a power plug or power cable, a control means for mounting in the power plug or power cable with the remote location-tracking circuit, an immobilizing circuit which is a power shut-down circuit for immobilizing a tool positioned within the tool casing, wherein the power shut-down circuit includes a relay; and a power cable connected between the control means and power shut-down circuit, the power cable being adapted to supply power to the tool, and the power shut-down circuit being controlled by the control means, wherein if the remote location-tracking circuit is removed by severing the power cable, thereby disconnecting the control means from the power shut-down circuit, the power shut-down circuit is configured to automatically shut down the power supply to the tool via the relay until the control means is re-connected.

In one example, the connector includes a body portion configured to be connected to a cord and a connection portion engaged with the body portion and comprising a plurality of conductors. The connection portion includes a conductive shield electrically connected to a plurality of the conductors when the connection portion is not engaged with the article of merchandise, and the connection portion also includes at least one ground conductor that is not electrically connected to the remaining conductors and/or the conductive shield when the connection portion is not engaged with the article of merchandise. At least one of the conductors and/or the conductive shield is configured to cooperate with the ground conductor to define a sense loop when the connector is engaged with the article of merchandise, and interruption of the sense loop is indicative of a security event.

The invention relates to a life vest container device, in particular aircraft seat life vest container device, for a life vest unit, with a life vest container comprising an accommodation unit that has an accommodation space as well as an access opening to the accommodation space, and with a monitoring device.

It is proposed that the monitoring device is at least configured to capture a change of at least one characteristic via at least one electric and/or electronic signal.

Methods and systems that selectively controls whether a battery is electronically connected to or disconnected from operational circuitry of an electronic device are described. The switching circuitry electronically connects the battery with operational circuitry in response to external electric power being available to the operational circuitry, thereby allowing the battery to be available as a backup source of electrical power for the operational circuitry when external electric power is lost. Methods and systems also electronically disconnect the battery from the operational circuitry in response to a loss of external electric power to the operational circuitry. As a result, undesirable battery drainage is avoided if the device is left in storage or is not being used for an extended period of time.

A battery system and a method of determining whether a battery system arranged onto a vehicle is connected to an external battery charging unit, are disclosed. The battery system includes a plurality of battery cells, first and second main terminals connected to the battery cells, and a charging interface comprising first and second contact points connected to corresponding first and second main terminals, wherein the battery system is arranged onto a vehicle and configured to be connected via the first and second contact points to an external battery charging unit for charging of the battery system, wherein the battery system includes a switch arranged between the first main terminal and the corresponding first contact point so as to allow disconnection of the first contact point from the first main terminal, wherein the battery system is provided with a voltage measurement member arranged to measure a voltage between the first contact point and a reference point having a potential substantially similar to the disconnected first main terminal, wherein the battery system includes a battery management circuitry arranged to control the switch and to receive a signal from the voltage measurement member, wherein the battery management circuitry is configured to determine, by comparing a value from the voltage measurement to a threshold value, whether the charging unit is connected to the first and second contact points of the battery system.

The system may be configured to perform operations including receiving battery information, such as voltage data, temperature data, battery-specific data, and/or application-specific data; and displaying at least a portion of such data on a graphical user interface on a display screen. The operations may further include analyzing at least a portion of the battery information to monitor or determine battery health and performance, and displaying the results of such analysis on the display screen.

In present solar panel theft protection system, a solar panel stops generating power after it is detached from its intended system or if the solar radiation level goes below certain min level. The accordance with the present disclosure solar panel & its connected system identify each other by encrypted codes. The solar panel & its connected system communicate with each other through same power cables which are coming from solar panel (i.e. positive & negative). No extra communication cabling is required.

Security systems and methods configured for use with an item of merchandise for retail display are provided. For example, a security system includes a sensor configured to be electrically connected to an internal power source of an item of merchandise and an alarm module configured to communicate with the sensor. The sensor is configured to receive power from the internal power source for performing one or more security functions, and the alarm module is configured to generate a security signal in response to a security event

A product-display system for displaying and securing a retail product. The system may include a retainer having a retainer bracket and a retainer body coupled to the retainer bracket. A retaining cable may be coupled to the retainer body at an opening in the retainer body. A fastener that may be unfastened to release the product from the retainer may only be accessed through the opening of the retainer body such that when the retaining cable is coupled to the opening, no fasteners of the retainer may be visible or accessible. The system may also include a display stem for holding the retainer and product. The display stem may include a recess for receiving at least a portion of the retainer body. The retaining cable may extend through the display stem and may simultaneously transmit power and data to a displayed product. The retainer may be returned to and held on top of the display stem using a retaining cable. The retainer may be oriented on top of the display stem in one or more predetermined positions through the use of magnetic forces.

An anti-theft module for a battery-operated electric machine tool includes at least a first data interface configured to transmit data to an external device. The anti-theft module also includes a position determination unit configured to determine a geographical position of the anti-theft module. The anti-theft module is configured to be installable as an adapter between a rechargeable battery interface of the electric machine tool and a replaceable battery.
