  • 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.

  • Patent number: 10159070
    Abstract: A user equipment (UE) may receive a wireless wide area network (WWAN) signal on a first antenna. The UE may process the WWAN signal with a portion of a WWAN receive chain of a WWAN module of the UE. The WWAN signal may be routed from the WWAN receive chain to a wireless local area network (WLAN) receive chain of a WLAN module of the UE. The UE may then process the WWAN signal with a portion of the WLAN receive chain.

  • Publication number: 20170325169
    Abstract: Power conservation in a radio frequency front end of a user equipment (UE) during wireless local area network (WLAN) communication is achieved by adjusting a power mode of the radio frequency front end. In one instance, the UE determines a signal strength of a received frame of a packet during a short training field of a preamble of the received frame. The determining occurs when a WLAN receiver is operating in a low power mode. The UE then switches the WLAN receiver to a high power mode during the short training field of the preamble or during a first segment of a long training field of the preamble when the signal strength is above a predetermined signal strength.

  • Publication number: 20160036512
    Abstract: Methods and apparatus for multiple wireless service coexistence are disclosed. The disclosed methodology and accompanying apparatus serve to engage one or more switching devices to connect/disconnect a first service transmitter to a first antenna, connect/disconnect a dual mode receiver and second service transmitter from the first antenna, connect/disconnect the second service transmitter from a second antenna, and connect/disconnect a diversity receiver to the second antenna. A first service transmit signal in a first service can then be transmitted or received using the first antenna, and a second service receive signal in a second service can be transmitted or received using the second antenna and the diversity receiver.

  • Patent number: 9170195
    Abstract: A method, apparatus and print process control strip determine a curing level of printing inks on printing material. Conventional measuring areas of a print process control strip are always formed by tonal value combinations of individual, reliably thoroughly dried, printing inks, in particular when using intermediate dryers. Measuring the measuring areas furnishes no more accurate information with regard to the curing level of ink combinations in the actual printed image which differ from the combinations of the measuring areas of the print process control strip. A level-of-curing control area is provided, which is formed by overprinting preferably at least four printing inks, in each case in full tone, to obtain statements relating to the curing level of the printing inks with the print process control strip. Measuring the level-of-curing control area provides information about the curing level of all printing ink combinations in the printed image.

  • Patent number: 8712339
    Abstract: Systems, methods and apparatus a provided for calibrating actual output power of a transmit power sensor for closed loop power control using a quality metric such as error vector magnitude (EVM) to improve power detection accuracy. In aspects, a method for correlating an output of a transmit power sensor with actual output power of a wireless transmitter includes deriving a characteristic correlation between an actual output power of a set of transmit amplifiers and an output power and of a set of corresponding power detection circuits over a range of transmit power levels in a corresponding set of wireless devices; storing the characteristic correlation in a wireless device that is not part of the set from which the characteristic correlation was derived; and sensing an output of a transmit power sensor of the device while the transmitter of the device transmits according to one or more gain settings.

  • Patent number: 8606193
    Abstract: An RF transceiver integrated circuit has a novel segmented, low parasitic capacitance, internal loopback conductor usable for conducting IP2 self testing and/or calibration. In a first novel aspect, the transmit mixer of the transceiver is a current mode output mixer. The receive mixer is a passive mixer that has a low input impedance. In the loopback mode, the transmit mixer drives a two tone current signal to the passive mixer via the loopback conductor. In a second novel aspect, only one quadrature branch of the transmit mixer is used to generate both tones required for carrying out an IP2 test. In a third novel aspect, a first calibration test is performed using one quadrature branch of the transmit mixer at the same time that a second calibration test is performed using the other quadrature branch, thereby reducing loopback test time and power consumption.

  • Patent number: 8594056
    Abstract: An apparatus and method are disclosed for effectively and efficiently arbitrating concurrent usage between WLAN and Bluetooth access technologies for co-located wireless devices. A state level arbiter determines state and relevant parameters of a WLAN module and of a Bluetooth module of a wireless transceiver unit. The state level arbiter uses the state and relevant parameters to determine which access technology (WLAN or Bluetooth) or combination of the access technologies (WLAN or Bluetooth) will provide the best concurrent performance for wireless transmissions at a given time for specific Bluetooth states and WLAN states.

  • Patent number: 8451759
    Abstract: A WCDMA enabled user equipment device configured to have functions collectively or selectively idle to conserve power. A discontinuous receiver is used to detect and read network messages and report the messages to the computer within the WCDMA enabled user equipment device. The computer then activates functions previously powered down to receive incoming messages for the user of the device. The discontinuous receiver is also used when the device is active to read network messages, freeing a modem of the device to operate on user messaging; and therefore, enhancing user related performance.
