摘要： An electronic device (100) for performing intelligent operations includes a housing (112), a manually operable input (118, 122) for providing information to the electronic device, and a material (124) positioned between the manually operable input and the housing. An electromechanical transducer (218, 220) has a mechanical connection consisting of to the manually operable input and an electrical connection for receiving power, wherein substantially all of a mechanical output from the electromechanical transducer is provided to the manually operable input, the material preventing the mechanical output from being transmitted from the manually operable input to the housing. An electric circuit (210) is coupled mechanically to the housing and electronically to the electromechanical transducer for driving the electromechanical transducer in response to the intelligent operations so as to cause the electromechanical transducer to generate a tactile response that can be felt by a user through the manually operable input.

摘要： An exemplary device and method for microfluidic transport is disclosed as providing inter alia a passive check valve (100), a fluid inlet channel (210), a fluid outlet channel (220) and a pumping cavity (240). The fluid inlet channel (210) is generally configured to flow a fluid through the check valve (100). The check valve (100) generally provides substantially passive means for preventing or otherwise decreasing the incidence of purged outlet fluid re-entering either the pumping cavity (240) or the fluid inlet channel (210). Accordingly, the reduction of backflow generally tends to enhance overall pumping performance and efficiency. Disclosed features and specifications may be variously controlled, adapted or otherwise optionally modified to improve micropump operation in any microfluidic application. Exemplary embodiments of the present invention representatively provide for substantially self-priming micropumps that may be readily integrated with, for example, existing portable ceramic technologies for the improvement of device package form factors, weights and other manufacturing and/or device performance metrics.

摘要： An exemplary composition of matter and method for making high-efficiency, low-loss capacitors is disclosed as including inter alia a B2O3—Bi2O3—ZnO glass in admixture with material typically comprising about 30-40 wt % cubic phase (Bi0.5Zn0.5)(Zn0.5Nb1.5)O7 and about 60-70 wt % pseudo-orthorhombic phase Bi2(Zn1/3Nb1/3)2O7 (e.g., “BZN”). The mixture effectively reduces the sintering temperature of BZN from the range of about 950-1050° C. to the range of about 850-900° C., thereby rendering BZN suitable for cofiring with, for example, existing LTCC dielectrics. Disclosed features and specifications may be variously controlled, configured, adapted or otherwise optionally modified to further improve or otherwise optimize the sintering temperature of BZN and/or BZN-based materials. Exemplary embodiments of the present invention representatively provide for embedded high-efficiency, low-loss capacitors that may be readily integrated with existing portable ceramic technologies for the improvement of dielectric properties, device package form factors, weights and/or other manufacturing, device or material performance metrics.

摘要： A microwave device has a monolithic microwave integrated circuit (MMIC) disposed therein for applying microwave radiation to a microfluidic structure, such as a chamber, defined in the device. The microwave radiation from the MMIC is useful for heating samples introduced into the microfluidic structure and for effecting lysis of cells in the samples. Microfabrication techniques allow the fabrication of MMICs that perform heating and cell lysing of samples having volumes in the microliter to picoliter range.

摘要： An exemplary method for making a micropump device is disclosed as providing inter alia a substrate (300), an inlet opening (310), and outlet opening (340), a pump chamber (370) and flapper valves (350, 360). The fluid inlet channel (310) is generally configured to flow a fluid through/around the inlet opening flapper valve (350). The outlet opening flapper valve (360) generally provides means for preventing or otherwise decreasing the incidence of outlet fluid re-entering either the pumping cavity (370) and/or the fluid inlet channel (310). Accordingly, the reduction of backflow generally tends to enhance overall pumping efficiency. Disclosed features and specifications may be variously controlled, adapted or otherwise optionally modified to improve micropump operation in any microfluidic application. Exemplary embodiments of the present invention representatively provide for substantially self-priming gas/liquid micropumps that may be readily integrated with existing portable ceramic technologies for the improvement of device package form factors, weights and other manufacturing and/or device performance metrics.
