Abstract: An antimicrobial protective film that can be applied to a surface such as a screen of a smartphone or computing device. The user is able to view items displayed on the screen and to interact with the screen via touch or the like. The protective film includes a base layer or film upon which a second layer is formed, and this second layer includes numerous structures, e.g., micro or nano structures. The structures have a geometry that is unfriendly for viruses and bacteria. The structures are embedded with antimicrobial and/or antiviral agents that migrate out of the structures and kill or at least detrimentally affect the viruses or bacteria received within the second layer. This effect is combined with the fact that the structures are made with geometries particularly devastating to microbes during elongation and contraction of the structures with the thermal-based expansion and contraction of the underlying base layer.

Abstract: A method for purifying waste water, and a dual chamber purification system, in which feed water may be passed first through a hybrid anion exchange unit, and subsequently through a weak acid cationic exchange unit. The hybrid anion exchanger may comprise a hybrid sorbent (HAIX-NanoZr) with dual functional sorption sites. The weak acid cationic exchanger may be a fiber having a shell-core physical configuration with relatively short intra-particle diffusion path length so that the ion exchange sites reside predominantly on the periphery. The system may be used to achieve partial desalination or TDS reduction and concurrent removal of target contaminants (e.g., phosphate, hardness). Further, the system may be regenerated using CO2 as the sole regenerant for both the hybrid anion exchanger and the weak acid cationic exchanger, thus producing spent regenerant with no externally added chemicals.

Abstract: The present invention includes an anion exchange method that uses sulfate-containing acid mine drainage (AMD), or any sulfate containing water resource, to remove strontium, barium, and/or radium from contaminated water sources, such as but not limited to hydraulic fracturing waste water, flowback, and/or produced water, without requiring any external regenerant. The removal process may be adopted with any waste water or impaired water source containing sulfate anions.

Abstract: Methods of automatically tracking a patching connection between a first connector port of a patch panel and a second connector port of a network device are provided in which a sensor is used to detect that a first end of a patch cord has been inserted into the second connector port. The patch cord has at least one data communications channel and a separate control channel. A first conductor of the control channel of the patch cord is biased to power an integrated circuit chip on the network device. In response to the detection by the sensor, a first signal is transmitted over the separate control channel of the patch cord to the network device. A second signal is received over the control channel of the patch cord in response to the first signal. The second signal includes a unique identifier that is associated with the second connector port.

Abstract: Disclosed is a method and tool that performs glass-to-glass testing of a test AV system. The test AV system may be a transmitter device that senses AV stimuli and transmits an AV signal to a receiver device that displays video and provides an audio out/speaker of the audio. A light source and a sound source may be placed at the transmitter device. A light sensor and microphone/direct audio out connection may be placed at the receiver device. The automatic test tool may cycle synchronized light/sound stimuli to the transmitter device and measure the delay/latency times for audio, video, and AV synchronization at the receiver device. The automatic test tool may be comprised of a computer running user interface/test management software connected to a low cost FPGA that controls the video/sound sources and sensors to accurately measure both video and audio glass-to-glass latency/synchronization in a continuous, automatic, and self-calibrating manner.
