Abstract: Devices comprising multi-compartment fluidic cell with multiple inlets. Compartments can be separated from one another using soft seals. The main cell can be located between two adjacent secondary cells. The main cell carries the main flow while the secondary cells can carry either the main flow or any auxiliary flows. The flow in the multi-compartment cells minimizes fluid leakage and causes reduced pressure difference between the main cell and the two secondary cells especially under similar flow conditions.

Abstract: Methods and systems for analyzing the detection enhancement of rectangular microcantilevers with long-slit microsensors. The deflection profile of the microcantilevers can he compared with that of typical rectangular microcantilevers under presence of dynamic disturbances. Various force-loading conditions are considered. The theory of linear elasticity for thin beams is used to obtain the deflection related quantities. The disturbance in these quantities can be obtained based on wave propagation and beam vibration theories.

Abstract: A cooling enhancement apparatus includes a first substrate and a second substrate, the first substrate having a face in contact with at least one hot medium and having another face in contact with a secondary gas. The second substrate includes a face in contact with the secondary gas and has the other face in contact with a main gas. The faces of the first and second substrates in contact with the secondary gas generally oppose each other. One or more flexible seals can be attached to the first substrate and to the second substrate to form one or more closed enclosures including the secondary gas so that the second substrate moves relative to the first substrate when the secondary gas undergoes volumetric thermal expansion.

Abstract: System and method for cooling of an integrated circuit utilizing Micro-Electro Mechanical Systems (MEMS) components. A flexible thin film has an upper flexible substrate, a lower inflexible substrate and flexible seals. One face of the lower substrate is in contact with at least one hot medium and the other face is in contact with a coolant fluid. One face of the upper substrate is in contact with the coolant fluid and the other face is in contact with the surrounding ambient. Two continuous flexible seals are attached to the faces of the upper lower substrates to form at least one closed enclosure comprising a thermally conducting gas. The thermally conducting gas is in direct contact with the lower substrate. The upper substrate deflects continuously and maximally in the direction along the coolant fluid flow direction when the flexible seals deflect when the thermally conducting gas undergoes volumetric thermal expansion.

Abstract: A DL-microchannel cooling device with rotatable separating plate is disclosed. The separating plate is supported via anti-leaking flexible seals. The only allowable motion for that plate is the rotational motion about a pivot rod. The rod is taken to be aligned along the microchannel center line normal to its sides boundaries. The device can be configured as a flexible microheat exchanger and a heated DL-flexible microchannel device. The theory of linear elasticity applied to flexible seals supporting the separating plate is used to relate the moment of the pressure forces on that plate to its rotational angle. The energy equations for both fluids flows are solved numerically and analytically under special conditions. As such, the effectiveness of the flexible microheat exchanger and other performance indicators for flexible microheat exchanger and heated DL-flexible microchannel devices are calculated.

Abstract: An assembly of microcantilever-based sensors with enhanced deflections. A deflection profile of an ?-assembly can be compared with that of a rectangular microcantilever and a modified triangular microcantilever. Various force-loading conditions can also be considered. A theorem of linear elasticity for thin beams is utilized to obtain the deflections. The obtained defections can be validated against an accurate numerical solution utilizing a finite element method with a maximum deviation of less than 10 percent. The ?-assembly produces larger deflections than the rectangular microcantilever under the same base surface stress and same extension length. Also, the ?-microcantilever assembly produces a larger deflection than a modified triangular microcantilever. The deflection enhancement increases as the ?-assembly's free length decreases for various types of force loading conditions.
