An RF PA operable in two or more selectable power ranges is disclosed. Switches configure the circuit for each range such that an amplifier device corresponding to the range provides final amplification, and all lower power amplifier devices also amplify the signal. An exemplary design includes a low power amplifier configurable for operation solo, or in parallel with a medium power amplifier, to deliver an appropriately matched signal either directly to the RF PA output, or first to the input of a high power amplifier for the highest power range. The signal in all ranges of the exemplary design is conditioned in part by the matching circuitry disposed between the high power amplifier and the RF PA output, which traverses no switches in high power range operation. The entire RF PA, including switches, control and matching circuitry, is fabricated on a single monolithic integrated circuit, an achievement may be facilitated by UTSI CMOS processing.

The invention includes sensors and sensing methods for determining cell morphology and/or chemical composition of an analyte. A porous substrate exhibiting a first optical signal is exposed to a target analyte and subsequently monitored for changes in the optical signal. More specifically, a photonic or porous substrate having a well-defined and highly tunable reflectivity or transmission spectrum, such as porous silicon (Si), porous alumina, porous Ge, porous GaAs, porous SiO2 and porous polymer, is used for example. A porous or photonic substrate is exposed to an analyte, such as a cell or other macromolecule, and changes in the scattered light are observed over time to determine cell morphology and/or chemical composition of the analyte using the substrate.

The invention provides porous particles that produce a predetermined optical response and that may be manipulated magnetically. A preferred particle of the invention has a porous structure that produces a predetermined optical response and magnetic material adhered to the particle. Another preferred particle is amphiphilic. The optical response provided by a particle of the invention enables particles of the invention to be used in sensing, labeling, signaling, display and many other applications. The magnetic nature of the present magnetic particles permits the particles themselves to be manipulated, e. g. , vibrated, moved and re-oriented. The porous particles can also be used to control, move, and/or deliver small volumes of liquids and solids associated with the particles.

In one example, a method includes receiving, by a server and from a plurality of computing devices, data representative of a group of gesture-shortcut pairs that each include a gesture having been detected by at least one computing device from the plurality of computing devices and a shortcut associated with the detected gesture, and wherein the shortcut corresponds to an operation to be executed by the at least one from the plurality of computing devices. The method includes sorting the data representative of each respective gesture-shortcut pair from the group of gesture-shortcut pairs into at least two subgroups, a first subgroup including the first gesture-shortcut pair and a second including the second gesture-shortcut pair, the sorting being based on detected similarities between at least one of each respective gesture from the group of gesture-shortcut pairs and each respective shortcut from the group of gesture-shortcut pairs.

A power amplifier with stacked, serially connected, field effect transistors is described. DC control voltage inputs are fed to the gates of each transistor. Capacitors are coupled to the transistors. The inputs and the capacitors are controlled to minimize generation of non-linearities of each field effect transistor and/or to maximize cancellation of distortions between the field effect transistors of the power amplifier in order to improve linearity of the power amplifier output.
