Abstract: An electronic monitoring bracelet, comprising a ring-shaped body configured so as to be mounted around a limb or an object, and an electronic monitoring system positioned in the body, the electronic monitoring system comprising an integrity detection system and an internal source of energy. The ring-shaped body is in the form of a rigid shell containing a chamber or several chamber sections in which are positioned components of the electronic monitoring system, the ring-shaped body entirely encircling the bracelet.

Abstract: A GNSS enabled device configured to process pulse per second (PPS) signals, in particular from a GNSS satellite constellation to determine a global position of the GNSS enabled device. The device comprises a GNSS receiver module configured to acquire the PPS signals, a computing unit, and a reference timer comprising a local reference clock and a timer circuit to measure periods of said PPS signals. The computing unit and reference timer are configured to measure a variance in jitter of said PPS signals to determine whether the received PPS signal is genuine or spoofed.

Abstract: An electronic monitoring bracelet, comprising a ring-shaped body (2) configured so as to be mounted around a limb or an object, and an electronic monitoring system positioned in the body, the electronic monitoring system comprising an integrity detection system (4) and an internal source of energy (12). The ring-shaped body (2) is in the form of a rigid shell containing a chamber or several chamber sections in which are positioned components of the electronic monitoring system, the ring-shaped body entirely encircling the bracelet.

Abstract: Electronic surveillance system (100) comprising an electronic surveillance bracelet (1) adapted to be secured around a limb of a wearer, the electronic surveillance bracelet (1) comprising an energy source (5), a processing unit (7), an identification generator (11), a localisation system (12), and at least one wireless communication system (9) adapted to communicate with a base station (15), characterised in that the wireless communication system (9) is adapted to receive communication from at least one further device (17) and to transmit a result of this communication to said base station (15) together with an identification signal generated by the identification generator (11).

Abstract: A comfort band is configured to be worn between an electronic surveillance bracelet and a leg of a wearer. The comfort band includes a tubular elastic element adapted to retain the comfort band on the leg of the wearer. The comfort band further includes a cushion provided along a lower edge of the elastic element so that the cushion is located towards the foot of the wearer. The cushion extends outwardly from the elastic element and is arranged so as to form an abutment for an end face of the electronic surveillance bracelet.

Abstract: A pet animal-wearable self learning device for has been disclosed. The device determines the status of the pet animal by analyzing wireless signal information gathered by the device over a predetermined period of time. The signal information is analyzed to identify useful patterns for determining the status of a pet animal. The pet animal status typically is a multi-dimensional, qualitative or quantitative indicator such as GPS Latitude/Longitude of the pet animal, safe or unsafe condition of the pet animal The status of the pet animal is determined by various factors/conditions such as identifying whether the pet animal is in an enclosed space or not, identifying if the pet is in extreme temperature not suitable for the pet animal's health, identifying whether the pet animal is moving or stationary, identifying if the pet-wearable device has been removed.
