  • Publication number: 20250083372
    Abstract: An apparatus and method for producing oriented polymer films are disclosed. The apparatus includes a curved enclosure configured to rotate and a flow obstacle. The curved enclosure has an interior volume with an opening at one end. The flow obstacle extends through the opening and interior volume, with one end rigidly coupled to a mounting plate. The flow obstacle's position is adjustable to contact the interior surface of the curved enclosure, defining a gap between them. The method involves introducing a material into the curved enclosure, adjusting the flow obstacle's position, and rotating the curved enclosure to generate an extensional flow within the material. The apparatus and method may be used for producing two-dimensional polymer films and can incorporate features such as inert gas flushing, heating systems, and various blade configurations for the flow obstacle.

  • Publication number: 20210292559
    Abstract: A method of additive manufacturing an article in the ZX (upright) orientation utilizes a composition including specific amounts of a polycarbonate-polysiloxane and polysiloxane-treated titanium dioxide particles. Although addition of titanium dioxide particles to a plastic composition typically reduces impact strength, articles additively manufactured from this composition exhibit improved impact strength relative to articles manufactured from a corresponding composition lacking the polysiloxane-treated titanium dioxide particles.

  • Publication number: 20160242548
    Abstract: A base supports an adjustable seat in the interests of automated weight shifting in order to relieve pressure. An orientation-adjusting system allows for the seat to be shifted to create aforementioned pressure relief. The seat has a sitting platform and a back support. The sitting platform is tiltable thanks to a joined tilting platform of the orientation-adjusting system. The back support can be inclined relative to the seat by means of a reclining mechanism of the orientation-adjusting system. A control module is programmed to direct shifting of the seat. The control module uses data gathered from a sensor system and an orientation feedback system to ensure that any adjustments made via the orientation-adjusting system are only performed when it is safe to so. A communication module and data storage unit further expand upon the capabilities of the system.

  • Patent number: 9261577
    Abstract: A method of estimating user location involving collecting data from the access points in the network. The data can then be used to define a relationship, for example the loss of power experienced by a transmitted signal, between the access points. The relationship can be stored within a matrix, database or any other suitable storage method that can be referenced to determine the position of a user device within the network and correlated with corresponding measurements from a user device to determine the location of the user device within the network.

  • Patent number: 9203147
    Abstract: Beamforming system and method which includes an inverse beamformer with first ports and second ports, a beamformer with beam ports and antenna ports, and antennas. The inverse beamformer may receive transmit signals provided to first ports, generates intermediate signals based on the transmit signals, and output the intermediate signals from the second ports. The beamformer's beam ports may couple to the second ports and the antenna ports, and may receive the intermediate signals at the beam ports, generate antenna signals based on the intermediate signals, and output the antenna signals at the antenna ports. The antennas may each receive an antenna signal from an antenna port, and transmit the antenna signal into space. The inverse beamformer may generate the intermediate signals in a manner that is mathematically inverse to the beamformer's generation of the antenna signals so that the antenna signals approximate the transmit signals up to respective phase shifts.

  • Patent number: 8934855
    Abstract: A base station for use in a mobile telephony network includes an antenna arrangement coupled to a transceiver arrangement for producing a plurality of beams. A method of testing the base station comprises detecting at the transceiver arrangement the signal strengths of a test signal received via the beams; comparing and/or correlating the said signal strengths detected at the transceiver arrangement; and using the results of the comparisons and/or correlations to determine the configuration of the antenna arrangement and transceiver arrangement and/or to detect faults. The comparison of average signal strengths can be used to detect cabling faults, and beam errors. The correlation of un-averaged signal strengths can be used to determine which beams have the same polarization. Beam pointing directions and the allocation of antennas to sectors can be determined by monitoring handovers of mobiles moving between cells. Frequencies may be allocated to sectors according to a frequency re-use scheme.
