A system including a cooling element and a support structure is described. The cooling element has a first side and a second side opposite to the first side. The cooling element is configured to undergo vibrational motion when actuated to drive a fluid from the first side to the second side. The support structure thermally couples the cooling element to a heat-generating structure via thermal conduction.

A blower including a duct configured to allow air to flow in and out and a plurality of blades disposed to be parallel to the duct. Each of the blades including a first part, a second part, and an airflow generator configured to generate airflow in a direction from the inlet to the outlet by applying a voltage between the first electrode and the second electrode which are disposed between a first electrode on a side of the inlet, a second electrode on a side of the outlet, and a dielectric. In a cross section of the blade in the airflow direction when cut in a cross section perpendicular to each of the blades, the first part has a thickness decreasing in a direction toward the inlet and the second part has a thickness decreasing in a direction toward the outlet.

A cell processing system, fluidics cartridge, and methods for using actuated surface-attached posts for processing cells are disclosed. Particularly, the cell processing system includes a fluidics cartridge and a control instrument. The fluidics cartridge includes a cell processing chamber that has a micropost array therein, a sample reservoir and a wash reservoir that supply the cell processing chamber, and a waste reservoir and an eluent reservoir at the output of the cell processing chamber. A micropost actuation mechanism and a cell counting mechanism are provided in close proximity to the cell processing chamber. A method is provided of using the cell processing system to collect, wash, and recover cells. Another method is provided of using the cell processing system to collect, wash, count, and recover cells at a predetermined cell density.

The present disclosure describes systems and methods for using an ionizing fluidic accelerator that may encompass the use of an ionizing fluidic accelerator including a substrate, an electron emitter having a negative bias and being formed on the substrate, an anode having a positive bias and being formed on the substrate, and an attractor having a negative bias and being formed on the substrate. The electron emitter and the anode may be separated in a first direction and the negative bias of the electron emitter and the positive bias of the anode may produce a first electric field in the first direction. The anode and the attractor may be separated in a second direction, the positive bias of the anode and the negative bias of the attractor may produce a second electric field in the second direction, and the second direction may be orthogonal to the first direction.

An oscillating fan includes a base, a plurality of heat sink fins arranged at the base and forming air outlet passages between the plurality of heat sink fins, a blade oscillating in a direction parallel to the plurality of heat sink fins, and a driving mechanism configured to drive the blade to oscillate, such that an airflow enters from a side of the blade distal from the plurality of heat sink fins and blows toward the plurality of heat sink fins.

A cantilever fan including a blade and a blade permanent magnet. The blade is clamped at one end to a base and has a distal end which is free to oscillate with distal end having the largest swept displacement of any portion of the blade. The blade extends from the clamped end to the distal end. The blade permanent magnet is attached only to the blade at a point along the blade's length and is free to move with the blade. The fan includes a stationary permanent magnet attached only to the base. The respective locations and relative orientation of the blade permanent magnet and stationary magnet result in a repulsive magnetic force between the blade permanent magnet and stationary magnet. The fan is configured so that the repulsive force increases as the blade's deflection brings the blade permanent magnet closer to the stationary magnet.
