Abstract: An enclosure or housing for an air monitoring instrument package for mounting on the roof or other surface on the outside of vehicles such as cars, trucks, buses, trams, trains and ships. By measuring air pollutants from moving vehicles, it is possible to explore the distribution of air pollutants throughout a city or rural area for the identification of sources of different pollutants, estimating human exposures to air pollutants, and mapping air pollutants with high resolution. The disclosed device provides continuous sampling of outside air while simultaneously protecting the delicate instruments from weather elements such as high wind, rain, snow, sleet and hail. The design also allows a nearly constant flow rate of sampled air independent of vehicle velocity. An optional impaction region further reduces transmission of mist and large particles to the chamber containing the measurement package.

Abstract: Embodiments described herein relate to an envelope tracking system that uses a single-bit digital signal to encode an analog envelope tracking control signal, or envelope tracking signal for brevity. In certain embodiments, the envelope tracking system can estimate or measure the amplitude of the baseband signal. The envelope tracking system can further estimate the amplitude of the envelope of the RF signal. The system can convert the amplitude of the envelope signal to a single-bit digital signal, typically at a higher, oversample rate. The single-bit digital signal can be transmitted in, for example, a low-voltage differential signaling (LVDS) format, from a transceiver to an envelope tracker. An analog-to-digital converter (ADC or A/D) can convert the single-bit digital signal back to an analog envelope signal. Moreover, a driver can increase the power of the A/D output envelope signal to produce an envelope-tracking supply voltage for a power amplifier.

Abstract: An arrangement of acoustic transducers for a flow meter. The flow meter is for measuring the rate at which fluid is flowing. The arrangement includes a respective transducer set for each edge of a notional regular polygon. The transducer sets are associated with a tubular cavity for carrying the fluid. Each of the transducer sets respectively includes two acoustic transducers oriented to define an acoustic path lying in a measurement plane of the respective set, and another two acoustic transducers oriented to define another acoustic path lying in the measurement plane of the respective set. The transducers sets are positioned so that, in a cross-section normal to the tubular cavity, the measurement plane of each respective transducer set is coincident with a respective edge of the notional regular polygon.

The network development environment may include an ability to apply changes directly to one or more network devices or to apply changes to stored “configuration files” that are associated with individual devices.

Abstract: A spray tip comprises a tip body, a tip piece, and a pre-orifice piece. The tip body has a fluid channel along a channel axis (AC). The tip piece is disposed within the fluid channel, and has a stepped, narrowing passage that terminates in an outlet orifice. The pre-orifice piece has an inlet passage, and is disposed within the fluid channel, abutting and immediately upstream of the tip piece. The pre-orifice piece and the tip piece together define a turbulating chamber therebetween.
