Abstract: A method and a computer program are described for developing a product (110), and services associated with the product, which product has at least one activation area (308) which is provided with a position code (403) that codes at least one position on an imaginary surface (601), which position causes a device (710) that detects the position code (403) to initiate an operation that utilizes information recorded by the device (710). A digital representation of at least part of the product comprising image points is produced, each image point in the digital representation of the activation area (308) corresponding to a position on the imaginary surface (601). A digital template that can be used for making the digital representation of the product is also described.

Abstract: A vessel pressure testing apparatus includes a safety retainer unit. An expanding plug unit is secured within a tubular outlet pipe of the vessel with a clamping bolt extending outwardly from an expanding rubber plug member. An attachment plate is secured abutting the outlet pipe with the clamping nut bearing on and locking the plate to the pipe and plug unit. A locking plate has a central opening larger than the external diameter of the pipe, and is passed over the pipe. A loop connector has one loop passed through an opening in the attachment plate and a second loop passed through a similar opening in the locking plate. The locking plate is located with the inner end spaced axially inwardly on the pipe relative to the outer end which is connected to the locking plate. Pressure is then applied to the vessel, and if the test plug fails for any reason, the plug unit tends to move from the pipe end.
