Abstract: Cell sorting methods are disclosed. A blood sample is provided. The blood sample is centrifuged to obtain a cell mixture having target cells and non-target cells. Fluorescent markers are added to the cell mixture to allow the fluorescent markers to bind with the target cells. A hydrogel solution is added and mixed with the cell mixture to form a mixture solution. The mixture solution is distributed to cell wells of an array chip, and the target cells and non-target cells in the cell mixture are spread on the bottom of the cell wells in a substantially monolayer manner. The mixture solution is cured. A fluorescence image analysis is performed to select the target cells that are bound with fluorescent markers and emit fluorescence, and the selected target cells are isolated.

Abstract: An oral care system includes an oral care implement and motion tracking attachment configured to allow tracking of the implement during an oral care activity such as tooth brushing. The oral care implement may include a handle and head. The tracking attachment is coupled to the implement and comprises colored tracking markers detectable by a programmable visual-based motion tracking unit. The tracking attachment in one configuration may comprise a housing with plural insertable tracking colored wedges. In another configuration, a colored tracking portion colored panels and optional colored neck band may be formed on or attached to the oral care implement. Both the tracking attachment and tracking portion embodiments as applicable facilitate tracking at least one of a position, orientation, movement, and the like of the oral care implement to which it is attached. The tracking attachment may be non-electric in nature without any onboard electronics in some embodiments.

Abstract: A fuel cell bipolar flow field plate and a fuel cell stack are provided. The fuel cell bipolar flow field plate includes a first gas channel and a second gas channel. Each of the gas channels has several sub-channels, each of the sub-channels has bending parts, and adjacent sub-channels have opposite flow directions. The sub-channels of the two gas channels form a four-leaf clover type pattern in a reaction area of the fuel cell bipolar flow field plate. A bending angle of each of the bending parts in the four-leaf clover type pattern is within 90 degrees.
