Abstract: Aspects are provided for positive displacement pumps and methods and systems for controlling such pumps for dispensing at a flow rate based on a downstream flow sensor. A pump controller determines a targeted motor speed for a flow rate set point based on a flow rate function. The pump controller determines a predicted movement time for a motor of the pump to change from a current motor speed to the targeted motor speed, a predicted wait time to reach a flow rate corresponding to the targeted motor speed, and a measurement time after the wait time. The pump controller controls the positive displacement pump according to consecutive control cycles, each control cycle includes a pump movement sub-cycle, a wait sub-cycle, and a measurement sub-cycle. The pump controller determines a measured flow rate during the measurement sub-cycle. A subsequent control cycle is based on the measured flow rate.

Abstract: Aspects are provided for positive displacement pumps and methods and systems for controlling such positive displacement pumps for accurate volume dispensing. The pump may run a calibration procedure to determine a mapping between a pump speed and a flow rate for a current configuration of the positive displacement pump, a tubing size, and a fluid characteristic. A pump controller may determine a pump motion profile based on the mapping. The pump motion profile includes an acceleration phase, a constant speed phase, and a deceleration phase such that a total volume pumped according to the pump motion profile and the mapping is equal to a target volume. The pump controller may determine an adjustment to the pump motion profile based on a constant flow rate measured during operation. The pump controller may decelerate the positive displacement pump according to the adjusted pump motion profile until the target volume is dispensed.

Abstract: The presently disclosed and/or claimed inventive concept(s) relates generally to the use of nonionic hydrophobically modified polysaccharides in personal care and household care compositions. More specifically, but not by way of limitation, the presently disclosed and/or claimed inventive concept(s) relates to the use of hydrophobically-modified cellulose ethers, such as hydrophobically-modified hydroxyethylcellulose (HMHEC) polymers in personal care and household care compositions. These compositions show pronounced syneresis in aqueous solutions or in the presence of surfactants, including nonionic surfactants and anionic surfactants such as lauryl sulfate (LS) and lauryl ether sulfate (LES). It is also contemplated that the surfactants used in the compositions be sulfate free and/or multi-tailed.

Abstract: Low passive intermodulation (PIM) antenna assemblies and methods for utilizing the same. In one embodiment, the low PIM antenna assembly includes an ultra-wide band quarter wave monopole over ground plane antenna apparatus that operates within a band from 698-5900 MHz. The radiating element is comprised of three (3) features that are separated from one another by one hundred twenty (120°) thus producing a triangular shaped pattern. Such a configuration reduces the nulls by about twenty percent (20%) as compared with similar antenna implementations having flat radiating elements. Moreover, in order to reduce the diameter of the ground plane while simultaneously increasing the electrical length of the ground plane, forming of the ground plane is required. Methods of using the aforementioned low PIM antenna assembly are also disclosed.

Abstract: To provide an optical nanofiber resonator having an optical waveguide whose diameter is equal to or smaller than the wavelength of a propagation light, a light emitter disposed at a predetermined position of the optical waveguide, and a first reflector and a second reflector formed in the optical waveguide with the light emitter interposed therebetween, wherein at least one of the first reflector and the second reflector transmits a part of the propagation light. With such a configuration, the channeling efficiency of the light emitted from the light emitter and the propagation mode of the optical waveguide is dramatically improved.
