  • Patent number: 10889063
    Abstract: A method of forming a textured effect on a substrate, the method comprising steps of: (a) creating a data file of an image having a thickness to be formed as the textured effect on the substrate, the data file comprising print image(s) and a number of times specified for printing of the print image(s); (b) preparing the data file for surface deposition by a printer; (c) providing the substrate on the printer; (d) the printer printing the print image(s) in the data file on the substrate using a layer of clear ink; (e) the printer UV curing the layer of ink; (f) repeating steps (d) and (e) for every print image of the print image(s) for the number of times specified in the data file such that the image formed as the textured effect on the substrate comprises a plurality of layers of printed and UV cured clear ink.

  • Patent number: 6661835
    Abstract: At a base station 2, a CDMA received signal coming in through an antenna 4 is fed to a radio frequency unit (RFU) or high frequency unit 6. The RFU 6 demodulates a baseband signal BB from a signal RF and delivers the signal BB to an analog-to-digital converter (A/D) 8. The resulting digital signal output from the A/D 8 is input to a hybrid interference canceller (HIC) 12 as a received signal Rx Data 10. The HIC 12 divides users into two groups and assigns one combination of a parallel interference canceller and a serial interference canceller to each group. The HIC 12 cancels interference contained in the received signal Rx Data 10 for thereby estimating symbols particular to a plurality of users.
