  • Patent number: 12101734
    Abstract: Differing operations of a wireless communication device benefit from different antenna configurations, such as for positioning, where closely spaced antennas are desirable, and data communication, where antenna diversity is desirable. A device is configured to receive a request for receive a request for determining a position of a user equipment (UE), select one of a first plurality of antennas or a second plurality of antennas for determining the position of the UE, receive wireless signals using the selected first plurality of antennas or the second plurality of antennas, and determine the position of the UE based at least in part on the received wireless signals.

  • Publication number: 20240165967
    Abstract: A method of curing UV inkjet ink in a printing machine includes two curing steps. In a first step, the inkjet ink is irradiated at high radiation power for a short irradiation time to pin the ink. In a second step, the pinned UV inkjet ink is irradiated with UV radiation of lower radiation power for a longer irradiation time to finally cure the ink. The light sources are UV light-emitting diodes or flash lamps whose radiation powers are modified by optical focusing or different electrical actuation. The process results in cured printed products of high quality.

  • Publication number: 20230345452
    Abstract: Aspects relate to wireless communication at a wireless communication device. The wireless communication device may include a transmitter configured to communicate using a first communication protocol, a receiver configured to communicate using a second communication protocol, different from the first communication protocol, a first antenna coupled to the transmitter, a second antenna coupled to the receiver and physically separated from the first antenna by a variable distance. The wireless communication device transmits, via the first antenna, a first transmission within a first frequency range, and receives via the second antenna, a second transmission within a second frequency range that overlaps the first frequency range.

  • Publication number: 20230300568
    Abstract: Disclosed are systems and techniques for wireless communications. For example, a first user equipment (UE) can receive positioning data corresponding to a second UE. In some cases, the first UE can determine a relative position between the first UE and the second UE. In some aspects, the first UE can determine a first location estimate of the first UE based on the positioning data corresponding to the second UE and the relative position between the first UE and the second UE.

  • Patent number: 11622281
    Abstract: A user equipment (UE) includes a first communication component configured to use a first frequency band, such as ultra-wide band (UWB), and a second communication component configured to use an intermediate frequency (IF) band that overlaps with the UWB band, such as an IF millimeter wave (mmWave) band. The second communication component conducts an IF signal along an internal signal conduction line that may interfere with UWB processing. A processor of the UE is configured to detect an indication of such interference, and, in response to the indication of interference, control the second communication component to adjust a characteristic of the IF band signal to mitigate the interference, such as by reducing its signal strength. The amount by which the IF band signal strength is reduced may be controlled to achieve a desired tradeoff between various performance metrics, such as power consumption and quality of service.

  • Patent number: 10252558
    Abstract: A method for operating a UV curing device in a printing machine includes providing a printing material to which a UV-curing fluid or UV printing ink or varnish is applied. The printing material is paper or foil moving in a transport direction and having a width. The fluid is cured by UV radiation emitted by a fluid-cooled first UV LED emitter of the device at least in an effective range thereof. The first UV LED emitter is operated in a curing mode and at a first power, and a fluid-cooled second UV LED emitter is operated in a temperature control mode different than the curing mode and at a second power lower than the first power and different than zero. The second power and the temperature of an LED array of the second UV LED emitter is selected to cause the LED array to be free from condensate.
