Abstract: The present invention provides a method and a system for monitoring the mobility levels of individual farm animals and accordingly determining their corresponding mobility score. The mobility score may be indicative of the health and/or welfare status of the animals. The present invention processes a 2D video recording obtained from an imaging device to detect the movement of individual animals through a space. The video recording is segmented over a set of individual frames and in each frame the individual instances of the animal appearing in the vide frame are detected. The detected instances of each animal over a number of frames are grouped together. From each detected instance of an individual animal a set of reference points are extracted. The reference points are associated with location on the animal body.

Abstract: An electromagnetic lock assembly includes a magnet block having a coil assembly and a connection for receiving an electrical current; and a control system having a detection circuit and an activation circuit, wherein the detection circuit senses a voltage across the coil and automatically sends an activation signal to the activation circuit when the voltage decreases from a supply voltage to a reference threshold voltage, the activation circuit increasing the electrical current through or the voltage across the coil assembly upon receipt of the activation signal. The electromagnetic lock assembly may further include an armature for coupling with the magnet block, wherein the supply voltage is configured by the control system to magnetically couple the armature and the magnet block absent an external separating force applied against the armature or magnet block.

Abstract: An electric strike assembly includes a housing formed with a recessed portion, a keeper pivotally arranged in the recessed portion of the housing, the keeper having an abutment, an actuator assembly having an actuator and an actuator paddle, and a blocking element rotatably mounted in the recessed portion of the housing, wherein cooperation of the actuator paddle with the blocking element is controlled by rotation of the actuator and determines a locking condition of the keeper based on a rotational position of the blocking element with respect to the abutment. In accordance with other aspects of the present disclosure, a locking system includes a door assembly having a latch, a door frame for mounting the door assembly, and an electric strike assembly mounted in the door frame. A method of controlling access through a door includes providing an electric strike assembly in accordance with aspects of the present disclosure.
