Abstract: The invention relates to a bioreactor for treating water fluid(s), and/or for producing a desired end product by biomass and/or for producing biomass. The invention relates also to methods for manufacturing and using such a bioreactor. The bioreactor (BR) includes at least a first processing unit (ZF), a second processing unit (Z2), a last processing unit (ZL), and, optionally, additional processing unit(s) (Z3, Z4) between the second processing unit (Z2) and the last processing unit (ZL) in a plug flow configuration; at least one forward circulation system (FCS, FCS1, FCS2) for circulating biomass (BM) from the first processing unit (ZF), to the last processing unit (ZL) and/or to additional processing unit(s) (Z3, Z4); and at least one reverse circulation system (RCS, RCS1, RCS2) for circulating biomass (BM) from the last processing unit (ZL) and/or from the additional processing unit(s) (Z3, Z4) to the first processing unit (ZF).

Abstract: The combined actuator described can be incorporated into a miniaturized camera product. In the camera product, the shutter driver uses the focus or zoom actuator's power amplifiers to control the current flow in shutter actuators. As such, the space needed for the camera's electronics is smaller and it is less expensive to manufacture the camera product.
