Abstract: A computer-implemented method of assessing the condition of a real-world object is provided. The computer-implemented method comprises: receiving sensor data depicting the real-world object; authenticating the received sensor data as genuinely depicting the real-world object; and if the authentication is successful, assessing a condition of the real-world object from the sensor data.

Abstract: A structural tie or strap in the form of a connector for use in the construction industry. The connector is substantially rectangular with fixing points at either end for fastening to walls or the like and includes an acoustic attenuation mechanism to enhance acoustic performance between the walls. The acoustic attenuation mechanism is embodied as folds, apertures and/or openings through the connector which prevent direct passage of sound and vibration waves through the connector, between the walls. An embodiment as a party wall strap is described.

Abstract: A hanger for connecting two adjacent members, such as I-Joists used in the construction industry. The hanger locates the members at approximately 90 degrees to each other and comprises a mounting means in the form of a plate for connection to a first member and support means connected to the mounting means to support a second member perpendicular to the first member. Embodiments are disclosed including features of stiffening ribs, tapered edges, and support feet to increase the load bearing capacity of the hanger.
