Abstract: Methods, devices, apparatuses and systems are disclosed for performing mammography, such as utilizing tomosynthesis in combination with breast biopsy.

Abstract: A supercharging arrangement for an internal combustion engine is disclosed. The supercharging arrangement comprises a supercharger having a rotational drive input, and a transmission having a rotational drive input to receive drive from an internal combustion engine, and a rotational drive output connected to the input of the supercharger. The transmission includes a variator operatively connected between the input and the output of the transmission, which variator has an output that is driven at an operating ratio from an input. There is a control system that operates to cause an engine to deliver an amount of torque that is indicated by the state of an input to the control system. The control system is further operative to set the operating ratio of the variator.

Abstract: There is disclosed a continuously variable ratio transmission unit of rolling traction type, comprising a pair of races (10,12) between which torque is transmitted by at least one roller (26), the roller being movable to provide variation in the transmission ratio and being subject to an adjustable roller reaction force by a roller actuator (28), a traction loading actuator (35) arranged to urge the rollers and discs into engagement with each other with a force which is varied in sympathy with the roller reaction force during normal variator operation, and a pre-loading arrangement (80) which is arranged to urge the rollers and discs into engagement with each other at least during a cold start wherein the pre-loading arrangement is adapted to apply a pre-loading force is reduced with increasing operating temperature.

Abstract: A multi-regime continuously variable ratio transmission has an output shaft (16), a variator and epicyclic gear sets (E1, E2) arranged coaxially to provide drive to two coaxial output shafts (20, 26). The drive from the coaxial output shafts (20, 26) is selectively connectable to an offset system output shaft (22) by means of high-and low-regime clutches (H, L) arranged coaxially with the system output shaft (22).
