摘要:
A automated teller machine (ATM) verifies the authenticity of the cheque based on image information acquired by a CIS unit and magnetic character information acquired by a MICR unit. The ATM further includes a plural cheque leaves determining unit for determining the presence of plural cheque leaves using the image information, the magnetic character information, and thickness information of the cheque.
摘要:
A linear amplification with nonlinear components (LINC) power transmitter is provided. The LINC power transmitter includes a digital signal processing unit which controls the LINC power transmitter; a frequency modulation unit which modulates or converts a digital signal output from the digital signal processing unit into a radio-frequency (RF) signal; a signal amplification unit which amplifies the RF signal output from the frequency modulation unit using a gain amplifier and a power amplification module; and a direct current/direct current (DC/DC) conversion unit which controls bias of the power amplification module. Here, the DC/DC conversion unit controls a base bias and/or a collect bias of the power amplification module, and the power amplification module operates in saturation.
摘要:
A waveguide structure includes a SOI substrate. A core structure is formed on the SOI substrate comprising a plurality of multilayers having alternating or aperiodically distributed thin layers of either Si-rich oxide (SRO), Si-rich nitride (SRN) or Si-rich oxynitride (SRON). The multilayers are doped with a rare earth material so as to extend the emission range of the waveguide structure to the near infrared region. A low index cladding includes conductive oxides to act as electrodes.

A fabrication method produces Si compatible light-emitting materials showing sizeable optical gain by thermally annealing thin film layers of Si-rich nitride (SiNx) By utilizing the Si compatible light-emitting material, light emitting devices can be fabricated that are compatible with CMOS processes. The Si compatible light-emitting material is a high index (refractive index ranging from 1.6 to 2.3) material allowing flexible design of high confinements photonic devices with strong structural stability with respect to annealing treatments. The Si compatible light-emitting material realizes broad band light emission by allowing resonant coupling with rare earth atoms and other infrared emitting quantum dots and better electrical conduction properties with respect to SiO2 systems. The Si compatible light-emitting material also realizes high transparency (low pumping and modal losses) in the visible range.

A fabrication method and materials produce high quality aperiodic photonic structures. Light emission can be activated by thermal annealing post growth treatments when thin film layers of SiO2 and SiNx or Si-rich oxide are used. From these aperiodic structures, that can be obtained in different vertical and planar device geometries, the presence of aperiodic order in a photonic device provides strong group velocity reduction (slow photons), enhanced light-matter interaction, light emission enhancement, gain enhancement, and/or nonlinear optical properties enhancement.
