Abstract: An prop of an attraction system includes a first plate, a second plate coupled to the first plate and configured to move relative to the first plate, and a biasing support coupled to and extending between the first plate and to the second plate. The biasing support includes a mesh structure and is configured to deform during relative movement between the first plate and the second plate, and the biasing support is configured to apply a force onto the first plate, the second plate, or both upon deformation.

Abstract: Apparatus for monitoring the cure of a bone cement material provided in a container includes a memory device in which data is stored relating to the time taken for the cement material of the type in the container to cure according to the temperature of the material. A data processor is used to calculate the time taken for the cement material to cure, based on data relating to the temperature of the cement material and data in the memory device relating to extent of cure. An output device is provided for data from the data processor relating to the extent of cure of the cement material in the container.

Abstract: Apparatus for monitoring the cure of a bone cement material which is provided in a container. The apparatus includes a radiation source from which radiation is directed towards cement in the container and a sensor for detecting radiation from the radiation source which has passed through cement in the container, and for generating a signal according to the intensity of the detected radiation. A data processor is used in monitoring changes in the intensity of radiation that is detected by the sensor due to changes in the opacity of cement in the container to radiation from the source as the cement cures.

Abstract: The present invention is directed, in various embodiments, to a hardware supported duplication token for arbitrating active and standby module states, a weighted state of health exchange for identifying unhealthy module states and relative module health states, and a packet sequence number synchronization technique for maintaining desired levels of synchronization between the active and standby modules.

Abstract: A device for use in the provision of bone cement to a bone cavity of a patient that includes a syringe body, and a tube that communicates with the syringe body. The tube is configured to supply bone cement from within the syringe body to the bone cavity. The tube comprises a polymer loaded with a thermochromic material.

Abstract: A method of monitoring the extent of cure of a mixed bone cement includes the steps of taking in hand a flexible polymeric film wherein loaded with a thermochromic material configured to change color at a predetermined temperature; wrapping a quantity of the mixed bone cement in the film such that the film is in contact with and tightly conforms to the mixed bone cement; and monitoring the film to identify a change in the color of the film, the change in the color of the film indicating that the mixed bone cement has reached the pre-determined temperature.
