摘要： A system that generates short charged particle packets or pulses (e.g., electron packets) without requiring a fast-switching-laser source is described. This system may include a charged particle source that produces a stream of continuous charged particles to propagate along a charged particle path. The system also includes a charged particle deflector positioned in the charged particle path to deflect the stream of continuous charged particles to a set of directions different from the charged particle path. The system additionally includes a series of beam blockers located downstream from the charged particle deflector and spaced from one another in a linear configuration as a beam-blocker grating. This beam-blocker grating can interact with the deflected stream of charged particles and divide the stream of the charged particles into a set of short particle packets. In one embodiment, the charged particles are electrons. The beam blockers can be conductors.

摘要： Techniques, systems, and devices are described for implementing for implementing computation devices and artificial neurons based on nanoelectromechanical (NEMS) systems. In one aspect, a nanoelectromechanical system (NEMS) based computing element includes: a substrate; two electrodes configured as a first beam structure and a second beam structure positioned in close proximity with each other without contact, wherein the first beam structure is fixed to the substrate and the second beam structure is attached to the substrate while being free to bend under electrostatic force. The first beam structure is kept at a constant voltage while the other voltage varies based on an input signal applied to the NEMS based computing element.

摘要： Methods, systems, and devices are disclosed for implementing molecular sensors. In one aspect, an ion-gas sensor device includes a pre-concentration module to collect and concentrate a gas-phase chemical for analysis; a piezoelectric fan to produce an air-flow through acoustic streaming to drive the gas-phase chemical released by the pre-concentration module to one or more downstream modules; an ionizer downstream from the piezoelectric fan to ionize the gas-phase chemical; and a gas sensor downstream from the piezoelectric fan and the ionizer to detect the ionized gas-phase chemical driven by the piezoelectric fan. The piezoelectric fan can include a stack of thin-film layers that includes a thin-film piezoelectric layer. The ion-gas sensor device is made into an ultra-portable package capable of integration with mobile communication devices, such as PDA devices or smart phones.
