  • Patent number: 8176819
    Abstract: The invention relates to a collision sensing device which can detect a collision between two or more objects. The collision sensing device comprises a deformable member (5) that defines a space (15) which can be assigned a pressure. In a first condition, the deformable member is undeformed, whereby the space (15) is assigned a first pressure (P1). In a second condition, the deformable member (5) is deformed whereby the space (15) is assigned a second pressure (P2). The pressure in the space is monitored. A collision with an object is detected when the pressure in the space changes from the first pressure to the second pressure. The invention can e.g. be applied in connection with machining, such as water jet cutting, but several other fields of application are also conceivable.

  • Patent number: 8025000
    Abstract: The portioning foodstuffs in three dimensions includes generating a three-dimensional map of the foodstuff, and then comparing the generated three-dimensional map of the foodstuff with the desired shape as stored in the memory of a computer. The computer determines the particular cutting path in three dimensions in order to arrive at the predetermined shape. This is followed by cutting in one direction to fix at least one dimension of the foodstuff, determining whether the foodstuff is within the tolerance limits or whether the foodstuff portion has moved during the first cutting operation. If so, the foodstuff is rescanned to generate a two-dimensional image of the foodstuff, followed by cutting the foodstuff to arrive at a portion trimmed along three dimensions.
