Abstract: Embodiments of the disclosure relate to digital-analog interface modules (DAIMs) for flexibly distributing digital and/or analog communications signals in wide-area analog distributed antenna systems (DASs). In this regard, in one aspect, a DAIM is a multi-functional device capable of distributing the digital and/or analog communications signals to a local-area DASs in a wide-area DAS. The DAIM comprises an analog radio frequency (RF) communications signal interface for coupling with an analog signal source, a digital communications interface for coupling with a digital signal source, an analog local distribution interface for coupling with a remote antenna unit (RAU), and at least one digital remote distribution interface for coupling with a head-end unit (HEU) of the local-area DAS. By employing the DAIM in the wide-area DAS, it is possible to flexibly reconfigure the wide-area DAS for distributing digital and/or analog communications signals over the digital communications mediums.
Abstract: The present disclosure relates to a process for cutting and separating arbitrary shapes of thin substrates of transparent materials, particularly tailored composite fusion drawn glass sheets, and the disclosure also relates to a glass article prepared by the method. The developed laser method can be tailored for manual separation of the parts from the panel or full laser separation by thermally stressing the desired profile. The self-separation method involves the utilization of an ultra-short pulse laser that can be followed by a CO2 laser (coupled with high pressure air flow) for fully automated separation.

Abstract: A method for making a porous inorganic membrane comprises using a mixture of an inorganic material, organic polymer particles and a solvent to form a slurry. The particles are non-spherical. The method further comprises distributing the slurry onto a surface, drying the slurry to remove the solvent and firing the dried slurry to produce the porous inorganic membrane. Examples of organic polymer particles include particles of acrylic. A substrate comprises a support with a porous inorganic membrane disposed on the support. The inorganic membrane has an average thickness of from about 0.5 micron to about 30 microns, a porosity of from about 30% to about 65%, a median pore size (d50) of from about 0.01 micron to about 1 micron, and a value of (d90?d10)/d50 less than about 2, as measured by mercury porosimetry. An example of a support includes an inorganic porous support.

Abstract: The micro-optical systems disclosed herein employ a glass tube having a body, a front end, a back end, an outer surface, and a bore that runs through the body between the front and back ends and that has a bore axis. The outer surface has a maximum outer dimension between 0.1 mm and 20 mm and includes at least one flat side. At least one optical element is inserted into and operably disposed and secured within the bore. The micro-optical assemblies are formed by securing one or more micro-optical systems to a substrate at the flat side of the glass tube. The glass tube is formed by a drawing process that allows for the dimensions of the glass tube to be small and formed with relatively high precision. An example of a compact WDM micro-optical assembly that employs micro-collimators is disclosed.

Abstract: Embodiments of the disclosure are directed to a coaxial connector with a translating grounding collar for establishing a ground path with a mating connector. The coaxial connector is configured to provide an electrical connection between two mating connectors. The coaxial connector includes a housing with a first conductor and a second conductor mounted within the housing. Further, the coaxial connector comprises a grounding collar mounted to the housing to provide a grounding of the coaxial connector with a mating connector that can discharge electro-static discharge build up before connections are established between the first and second conductors and a mating connector. Thus, the coaxial connector is grounded before establishing an electrical connection between the coaxial connector and a mating connector while also compensating for tolerance stack variability in the coaxial connector.

Abstract: A gain level control circuit in a wireless distribution system (WDS) is provided. The digital level control circuit receives a number of first digital communications signals having a number of first digital amplitudes and generates a number of second digital communications signals having a number of second digital amplitudes. When a selected second digital amplitude approaches a full-scale digital amplitude represented by a predefined number of binary bits, the gain level control circuit determines a selected first digital communications signal having a selected first digital amplitude causing the selected second digital amplitude to exceed the full-scale digital amplitude and adjusts the selected first digital amplitude to reduce the selected second digital amplitude to lower than or equal to the full-scale digital amplitude.
