A high-speed radiographic silver halide film is useful for radiography to provide images with improved contrast and sharpness and reduced fog. A carrier part is inserted into the rubber-elastic sliding block body, this carrier part having greater strength and stiffness than the sliding block body and being pivotally supported on a support pin. The location estimate for each individual co-located sector transceiver can be updated as a centroid of all of the co-located sector transceivers. A first valve position for a first electronic evaporator pressure regulator associated with a first refrigeration circuit is determined based on the determined change in suction pressure set point, which is based upon the measured parameters from the lead circuit. The identifier is associated with certain information regarding the container and biological sample. The ice then flows from the outlet of the ice crusher down an ice chute or other outlet of the ice crusher, into a cup or container as desired.
