Abstract: Table top sanitizer dispenser bottle bases are disclosed herein. An exemplary table top sanitizer dispenser bottle base includes a movable upper housing, the upper moveable housing has a floor with an aperture located therein and a peripheral wall. The top sanitizer dispenser bottle includes a lower stationary housing. The upper movable housing is connected to the lower stationary housing and is configured to move linearly upward and downward with respect to lower stationary. One or more biasing members bias the upper movable housing upward. A switch is included and the upper movable housing has an engagement member or surface for actuating the switch upon downward movement of the upper movable housing. At least one of a visual indicator and an audible indicator are also included. Control circuitry is provided for activating the one or more of a visual indicator and audible indicator when the engagement member actuates the switch.

Abstract: A method to identify a compound of interest includes the step of subjecting a sample to a plurality of colorimetric spot tests to yield a plurality of resultant test colors. The resultant test colors are compared with reference colors to define a set of sample reference colors. Indexed reference color sets indexed for the compound of interest are provided. The indexed reference color sets are searched with one or more of the sample reference colors for a match with the set of sample reference colors. The identity of the sample as the compound of interest is then determined. A device and a system to identify compounds of interest are also disclosed.

Abstract: A reclosable package is described that includes a package integrity feature defined by an inner film layer of the package. The package integrity feature includes a first die cut portion and a second die cut portion that both extend from a main die cut portion at least partially defining the opening of the package. The first and second die cut portions are continuous with each other and with the main die cut portion, such that they are defined by a single cut line. In some cases, the package integrity feature includes a neck region that tears when the package is opened and an anchor region that resists delamination. Because the first and second die cut portions are continuously formed with each other, the anchor region may have a circular or elliptical shape and is, thus, easier and more consistently manufactured, allowing for better performance.

Abstract: A low-cost and reliable radio warning system that alerts system users of potential hazardous conditions is disclosed. The system makes use of a transmitter and at least one receiver. The transmitter generates and transmits a radio warning signal that carries a digital data sequence that includes information concerning a particular potential hazardous condition from which the transmission was initiated, such as an approaching ambulance, fire truck, bus, train, or the like. Other information, such as GPS coordinates, may also be included. Through the use of digital encoding techniques, the system's susceptibility to false alarms or "false triggers" is minimized. The radio warning signal is transmitted in burst transmissions and may use a number of signaling techniques, including spread spectrum transmission, which increases system reliability and performance even in the presence of interference or multipath distortion.
