20130048635 | Oil-less pressure relief valves - A self contained one-way pressure relief valve for application to product packaging that does not require the addition of a sealing lubricant. Atop a base with an opening extending through is an adhesive-like material layer, and a dry strap of a silicone or other release film coated membrane, all of which are of gas impervious materials. The release coated material layer covering the opening with the release film in contact with the adhesive-like material creating a surface attraction between the release film and the adhesive-like material. An intermediate layer of gas impervious material with an opening extending through provides for including a gas pervious filter material layer that may be for fine particulates or liquid proof. | 02-28-2013 |

An intermediate layer of gas impervious material with an opening extending through such layer may be provided. A gas pervious filter material layer may be provided to block passage of fine particulates or liquid. | 10-30-2014 |
20150135967 | Single-Serve Cartridge with Pressure Relief Valve - An improved single-serve cartridge with a one-way gas pressure relief valve for beverage brewing, preferably in an automatic single-serve beverage brewer device such as the Keurig® Single Cup Brewing System, and cartridge components are described. In embodiments, the improved cartridge contains ground coffee or other particulate beverage medium. A one-way gas pressure relief valve permits gas produced by the ground coffee to escape from the cartridge before use of the cartridge in a brewer, thereby avoiding certain disadvantages associated with excessive pressure within the cartridge. The one-way gas pressure relief valve is also essentially liquid-tight to liquid injected into the cartridge by the brewer avoiding problems associated with liquid leakage and allowing the cartridge to function in the brewer in the same manner as an unmodified cartridge. The improved cartridge enables ground coffee, in particular, to be packaged immediately following roasting and grinding when at its optimal freshness to provide for improved beverage flavor and quality while maintaining package quality and integrity. | 05-21-2015 |

20080212969 | METHOD AND APPARATUS FOR USING DISTRIBUTED ANTENNAS - A distributed antenna system for using distributed antennas provides for locating a plurality of distributed antennas on existing infrastructure such as existing utility poles, traffic lights/signals, streetlights, etc. Each of the distributed antennas is connected to a base station hotel using a fiber optic cable. The distributed antenna system allows users to access wireless services provided by a plurality of carriers and using a plurality of communication technologies using a truly shared network and without having to implement duplicative wireless infrastructure components. | 09-04-2008 |
20100296816 | Flexible Distributed Antenna System - An apparatus and method for implementing a flexible distributed antenna system (DAS) head end are disclosed. A flexible DAS head end includes an RF conditioning module configured to be connected to one or more base station transceiver (BTS) devices and one or more low-power RF modules that are also part of the flexible DAS head end. In an example embodiment, the flexible DAS head end receives high-power digital-RF passband transmissions from its connections to the one or more BTS devices, and low-power digital-RF passband signals from the one or more low-power RF modules. The low-power RF modules, in turn, can receive input baseband signals from one or more baseband units (BBUs) in a wireless network, and then convert the input signals to the lo low-power digital-RF passband signals. The RF conditioning module constructs one or more superposition RF signals from the passband signals, and routes and transmits them to an array of antenna nodes. | 11-25-2010 |
20110028157 | Real-Time Location Determination For In-Building Distributed Antenna Systems - A system for determining the location of a wireless mobile device with respect to an interconnected network of wireless transmission waveguides is disclosed. The interconnected network could be interconnected ducts of an HVAC system in a building. Multiple wireless probes are placed at multiple locations within the HVAC duct system (or similar interconnected network of waveguides). Each probe may detect a common signal from a wireless mobile device and independently preserve arrival time information of the detected signal, wherein the signal propagates to probes by way of a free-space path to an opening in one or another duct, and thereafter to the probes via one or another path through the interconnected ducts, which act as wireless transmission waveguides. By correlating timing information of a signal received at three or more probes, a location of the mobile wireless device may be determined by one or another form of triangulation. | 02-03-2011 |

20130182698 | PN Selection for RF Repeaters, Bi-Directional Amplifiers or Distributed Antenna Systems - Presented herein are methods and systems for providing network access at a slave node based on a signal transmitted by a master BTS. In one example, a pseudorandom code (PN code) selection is described, in which each slave node has a known associated time offset and data is transmitted with a PN code advanced by the known time offset and the propagation delay. Using an example slave base station transceiver architecture (or just slave node for short), the “traditional” BSC can be removed from at least one base station (e.g., “slave nodes”) and a master base station may be configured to control the signal being transmitted from each slave node. Each slave node then may transmit and receive RF signals. The master BTS head end may receive signal portions from the slave nodes and mobile devices, and combine them for relay back into the network. | 07-18-2013 |
20130189941 | Local Management And Control Of Remotely Subscribed Wireless Communication Devices - A mobility gateway may authenticate a first wireless communication device (WCD) with a first wireless operator. The first WCD may subscribe to the first wireless operator, and may be served by a first wireless coverage area that is defined by a first carrier frequency. The first carrier frequency may be associated with the first wireless operator. The mobility gateway may also authenticate a second WCD with a second wireless operator. The second WCD may subscribe to the second wireless operator, may be served by a second wireless coverage area that is defined by a second carrier frequency. The second carrier frequency may be associated with the second wireless operator. The mobility gateway may route network traffic between a local network point of presence and at least one of the first and second WCD. | 07-25-2013 |
