    摘要： An electric powered bicycle includes front and rear wheels (102, 104) that swivel relative to a midframe (106). The midframe (106) includes a pedal driven generator-motor (108), and each wheel (102, 104) includes a motor-generator. The wheels (102, 104) may swivel to opposite sides of the midframe (106) about 180° to move into a collapsed configuration. Swivel may be on single axis joints (162, 168) with tilted swivel axes. In the collapsed configuration, the bicycle is suitable to be carried and stored and may also be utilized in a unicycle/exercycle configuration. By swiveling the wheels (102, 104) to the same side of the midframe (106) about 90°, the bicycle can be placed into other configurations including a walker, a rolling seat, and a chariot to carry packages or a person.

    摘要： Imaging spectrometers can be used to generate hyperspectral images for medical diagnoses, contaminant detection, and food safety inspections, among other applications. An exemplary imaging spectrometer includes an integrated position sensing array that measures the relative positions of the interferometer components based on an interference pattern generated by illuminating the interferometer with a reference beam. Such an imaging spectrometer includes a processor that controls the interferometer component position by actuating a voice coil and several piezo-electric elements to align the components with respect to each other and to provide a desired optical path length mismatch between the interferometer arms. In some cases, the processor may use feedback and feed forward control, possibly based on the actuators' transfer functions, for more precise positioning. The processor may also implement adaptive and recursive spectral sampling to reduce the image acquisition period.

    摘要： A miniature, low cost mass spectrometer capable of unit resolution over a mass range of 10 to 50 AMU. The mass spectrometer incorporates several features that enhance the performance of the design over comparable instruments. An efficient ion source enables relatively low power consumption without sacrificing measurement resolution. Variable geometry mechanical filters allow for variable resolution. An onboard ion pump removes the need for an external pumping source. A magnet and magnetic yoke produce magnetic field regions with different flux densities to run the ion pump and a magnetic sector mass analyzer. An onboard digital controller and power conversion circuit inside the vacuum chamber allows a large degree of flexibility over the operation of the mass spectrometer while eliminating the need for high-voltage electrical feedthroughs. The miniature mass spectrometer senses fractions of a percentage of inlet gas and returns mass spectra data to a computer.

    摘要： A needle-free transdermal transport device includes a chamber (900) for holding the substance to be injected, a nozzle (910) in fluid communication with the chamber, and a drug reservoir (950) for storing the substance to be transferred to the chamber. The needle-free transdermal transport device also includes a controllable magnet and coil electromagnetic actuator (242) in communication with the chamber. The actuator receives an electrical input and generates in response a force. The force then causes a needle-free transfer of the substance from the chamber to the biological body. The force is variable responsive to variations in the received input during actuation. The actuator draws the substance from the drug reservoir or alternatively, the substance can be pressurized from the drug reservoir into the chamber by a pressure source.

    摘要： A medical device includes a sensor that is configured to measure a property of an outer layer of an anatomical body surface. The sensor includes a source probe configured to stimulate a local surface of the outer layer of an anatomical body surface. The sensor also includes a detector configured to measure a response of the outer layer resulting from the source probe stimulation. A controller coupled to the source probe and the sensor drives the source probe using a tailored stochastic sequence and determines the property of the outer layer using the measured response received from the detector. The sensor can be used with medical devices, such as drug delivery devices including microneedle transport devices and needleless injection devices.

    摘要： The synthesis of thiophene based conducting polymer molecular actuators, exhibiting electrically triggered molecular conformational transitions is reported. Actuation is believed to be the result of conformational rearrangement of the polymer backbone at the molecular level, not simply ion intercalation in the bulk polymer chain upon electrochemical activation. Molecular actuation results from π-π stacking of thiophene oligomers upon oxidation, producing a reversible molecular displacement that leads to surprising material properties, such as electrically controllable porosity and large strains. The existence of active molecular conformational changes is supported by in situ electrochemical data. Single molecule techniques have been used to characterize the molecular actuators.
