A two-wheeler lock, in particular a frame lock, wherein the lock is preferably at least partly drivable in a motorized manner, comprises a sensor for detecting different positions of an element of the lock movable along a defined movement path. The movable element here has a permanent magnet and the sensor is configured as a magnetic sensor. This magnetic sensor is furthermore configured for a three-dimensional magnetic detection to detect positions or movements of the movable element deviating from the defined movement path and/or to detect manipulation attempts by means of external magnets.

A mobile alarm apparatus includes a detection apparatus for detecting positional changes of the alarm apparatus; an output apparatus for the output of alarm signals; and a control apparatus for controlling the output apparatus in dependence on detected positional changes. The control apparatus is operable in a monitoring mode and in an alarm mode. In the monitoring mode, the control apparatus is configured to control the output apparatus to output a pre-alarm and to change into the alarm mode when a detected positional change is within a first range of significance. In the alarm mode, the control apparatus is configured to change into the monitoring mode when a predefined time period has elapsed since the last output of an alarm signal and otherwise, when a detected positional change is within a second range of significance, to control the output apparatus to output a main alarm different from the pre-alarm.

The invention relates to a transportable device for preventing a loss of a movable object, comprising a protective housing (2) for protecting the device (1), an electronic alarm device (35), which is arranged in the protective housing (2) and has an anti-theft alarm function, and fastening means (11) for detachably fastening the device (1) to the movable object, wherein the fastening means (11) comprise at least one wrap-around element (12; 46; 52; 59; 68) for wrapping around at least one part of the movable object and wherein the wrap-around elements (12; 46; 52; 59; 68) can be fixed by means of locking elements (19, 20, 21; 49, 50, 51; 55, 57, 58; 61, 63, 64, 65; 71, 72, 73), which are arranged in the protective housing (2), wherein the locking elements (19, 20, 21; 49, 50, 51; 55, 57, 58; 61, 63, 64, 65; 71, 72, 73) can be selectively opened and closed by means of a lock device (13) rigidly connected to the protective housing (2), and wherein additionally the protective housing (2) can be selectively opened and rigidly connected to the protective housing (2), and wherein additionally the protective housing (2) can be selectively opened and closed by means of said lock device (13) and access to at least one chamber (18, 33) in the protective housing (2) is thereby enabled.

A closure for a strand lock having a securing strand, a locking pin with a latch, and a locking housing defining a receptacle for the locking pin is provided with a rotatable coupling element on the locking pin. Rotation of the coupling element secures the latch in the housing.

A security tag including: a housing and circuitry which detects a locked state, the circuitry configured to execute a signal transfer function responsive to interchanging a pin and a lanyard in the circuitry, and/or the housing including a replaceable battery compartment locked by inserting either the pin or the lanyard into a lock mechanism which differently secures the pin and the lanyard; and an alarm, in communication with the circuitry, triggered by an undisarmed breach of the locked state.

A lock having an alarm function for a two-wheeler comprises a lock body and a securing hoop movable relative to the lock body between a securing position for securing the two-wheeler and an open position for releasing the two-wheeler. The lock body has a locking mechanism to selectively lock the securing hoop to the lock body in the securing position, and further comprises an alarm device for outputting an alarm signal. The locking mechanism can selectively be moved into an unlocked position, a locked position, or an alarm activation position, with the securing hoop being released for a movement into the open position in the unlocked position, with the securing hoop located in the securing position being locked at the lock body in the locked position, and with the alarm device being activated or being able to be activated by moving the locking mechanism into the alarm activation position.

A first portion of a security device, the first portion configured to have a separate state with respect to a second portion and a combined state with respect to the second portion, such that when in the combined state, the first portion is mated, interlocked, and/or locked with the second portion to collectively form the security device.

A cable lock (10), including: a cable (16), for locking an object (26) thereby; a first, being the internal peripheral electric conductor (54B), surrounding the cable (16); a peripheral insulating layer (22), surrounding the first peripheral electric conductor (54B); a second, being the external peripheral electric conductor (54A), surrounding the peripheral insulating layer (22); and an electrical circuit (62), for alerting (56) once any region (58A) of the second peripheral electric conductor (54A) electrically contacts an adjacent region (14A) of the first peripheral electric conductor (54B), by crossing the peripheral insulating layer (22), thereby a blade (28) pressing on the second peripheral electric conductor (54A) induces the electrical contact of the second peripheral electric conductor (54A) with the first peripheral electric conductor (54B), thereby the electrical circuit (62) alerts (56) prior to cutting the cable (16).

A smart security device comprising: a housing, and electronics provided in the housing, the electronics comprising a tag uniquely associated with the smart security device and configured to automatically and periodically emit a first signal, the first signal being a Bluetooth signal configured to be sent and received via a Bluetooth low energy wireless personal area network; and a NB-IoT module configured to send and receive signals via a NB-IoT network.

A closure for a strand lock having a securing strand, a locking pin with a latch, and a locking housing defining a receptacle for the locking pin is provided with a rotatable coupling element on the locking pin. Rotation of the coupling element secures the latch in the housing.
