Abstract: Disclosed is a refiner filling piece for a refiner having a rotor that rotates about an axis of rotation and cooperates with a stator to mechanically treat a pulp containing cellulosic fibers. The refiner filling piece is mountable to the rotor or the stator. The refiner filling piece comprises a base and a plurality of spaced-apart refiner bars, each refiner bar having a leading surface and a trailing surface. At least one of the refiner bars has a leading surface coated with a first coating and a trailing surface coating with a second coating. The first and second coatings have different chemical compositions and/or different physical properties. Alternatively, the first and second coatings may be applied to distinct portions of the same surface.

Abstract: A control system for ambient air exchange with a machine room or similar enclosure controls an exchange rate of the ambient air based on a temperature differential between the inside (machine room) and outside temperatures, rather than absolute thermostatic controls based solely on the interior temperature. A larger temperature difference between the inside and outside air means a greater cooling potential for the exchanged air. Ambient air exchange is performed by dampers/louvers/vents and a fan speed driving the air exchange. Control of the fan speed based on the temperature differential allows lower fan speeds for controlling the temperature when the temperature differential indicates ample cooling. Higher fan speeds, incurring additional electrical consumption and fan noise, are only needed when a relatively small differential limits the cooling ability of the exchanged air.

Abstract: A method, computer program product, and computer system for remote conference security control. The method includes monitoring an audio and/or a video input for participants at one or more remote locations of a remote conference meeting irrespective of sharing of the audio and/or the video input at the time of monitoring. The method compares an extraction of a detected voice and/or face input with a registered profile of the participant to detect non-registered participants. When detecting a non-registered participant, the method provides an output action to at least some of the participants of the remote conference meeting to the non-registered participant.

Abstract: A communication system is disclosed in which am anchor base station receives, from a core network node, downlink data for a communication device. The base station attempts (e.g. by RAN-based paging) to initiate communication with the communication device, and when the communication device does not respond to the attempt to initiate communication, the base station sends a message to the core network node, the message requesting initiation of a paging procedure for the communication device (e.g. S1-based paging).

Abstract: A wireless communication system includes one or more base stations able to divide resources between multiple network operators sharing the base station. A shared base station is configured to monitor a contribution to the load on the base station associated with network operators sharing the base station resources and to provide the determined contribution to the load to one or more other base stations for use in load balancing between the base stations.

Abstract: There is presented a method performed by a central unit of a distributed base station apparatus in a cellular communication system, as part of a change of a UE context from a source distributed unit to a target distributed unit. A first message is sent to the target distributed unit of the distributed base station apparatus. A second message is received, from the target distributed unit of the distributed base station apparatus. The second message includes configuration information for the target distributed unit which may be full or delta. A third message is sent to a further base station apparatus that contains the received configuration information for the target distributed unit and an indication of whether a full or a delta type of configuration, has been used.

Abstract: Promotional materials are presented to a user according to user-experience as defined by certain parameter values detected during operation of a computing device. Operation of the computing device may include playing a video game. The operation of the computing device is monitored for non-conforming parameter values with respect to ideal parameter values. The promotional items disclosed in the promotional materials are identified as a way to improve the current user experience if added to the current computing system.

Abstract: A method is presented in which a central unit of a distributed base station apparatus in a cellular communication system sends to a distributed unit of the distributed base station apparatus a first message comprising an information element for requesting the distributed unit of the distributed base station to provide a current distributed unit configuration. The central unit receives, from the distributed unit of the distributed base station apparatus, configuration information for the current distributed unit configuration in a second message sent in response to the first message.

Abstract: An environmental control system for a telecom shelter integrates with a native HVAC system for exchanging interior air in a conditioned space in a machine room, telecom enclosure, or other closed machine environment by forcing or directing cooler outside air to replace interior air without active refrigeration by the native HVAC system. Primary cooling and heating of the conditioned space in the enclosure is performed by an exchange system and control logic that identifies, based on sensory input, when outside air exchange is more efficient than native AC (Air Conditioner) operation. The native AC system is suppressed or inhibited, and primary environmental control performed by fan driven exchange of outside air with air in the enclosure.

Abstract: A ventilation system maintains a temperature for a computer equipment enclosure using a combination of air conditioning and outside (ambient) air exchange based on a graphical user interface (GUI) for setting a range of temperature at which the ventilation system maintains the temperature. Cooler temperatures allow ambient air exchange to keep the temperature sufficiently low, while air conditioning is invoked when exterior temperatures rise.
