A photonic crystal includes a plurality of photonic crystal slabs that is suited for confining TE polarizations and TM polarizations. The photonic crystal slabs include alternating slabs of dielectric rods and air holes. The alternating slabs create a lateral symmetry plane. The alternating slabs of dielectric rods and air holes further include planar line defects resulting in the formation of defect bands inside the bandgap of the photonic crystal.

The circuitry of the present invention taps a DS0 data stream and outputs a timing signal to drive terminal multiplexers. Even if the data bit stream is lost, the present invention continues to provide proper clocking signals. A composite clock (bit and byte clock) is provided by the present invention with the bit clock at 64 KHz and the byte clock at 8 KHz in the preferred embodiment. To avoid the problem of phase shift over long distances (limiting cable length) the present invention phase adjusts the digital bit stream clocking signal with a 360 degree delay, giving the appearance of advancing the signal in phase. An additional delay of one frame width is applied to the signal. A negative phase delay equivalent to cable runs from 0-1500 feet in 500 foot increments is also applied. In the preferred embodiment, a shift register is tapped in reverse order to accomplish this phase delay.

The present invention provides a clock holdover circuit which will provide a replacement clock signal within predetermined parameters independently of time and temperature variations. The circuit of the present invention has only a single component which is time and temperature dependent. By selecting the components parameters to be within the desired tolerances, the accuracy of the circuit is maintained. In the present invention, digital circuitry is combined with an accurate local crystal frequency source to provide a replacement clock signal. The present invention allows phase consistency upon loss of a reference clock signal as well as on return of the reference clock signal. A reference clock signal is phase locked to a VCO to produce a desired output. The frequency of the output is compared to a local frequency standard to generate an offset frequency used to control a frequency synthesizer. The offset frequency is digitally stored. Upon loss of the reference clock signal, the stored offset frequency is used to drive the frequency synthesizer along with the local frequency standard so as to provide an acceptable replacement clock signal. The frequency comparator, storage, and synthesizer are all digital so as to be time and temperature independent. The local frequency standard is crystal based having known time and temperature tolerances. By choosing a local frequency standard having tolerances within a predetermined range, an acceptable clock holdover signal may be provided indefinitely. The replacement clock signal is phase compared to the reference clock signal so that no loss of phase occurs upon reference loss.

The bezel assembly for data reception, for use with a bill validator in a financial transactional device, includes a bezel housing and a data reception assembly. The bezel housing includes a customer-facing front portion and a back plate connectable to the bill validator that is mounted within the transactional device cabinet. The front portion includes an insertion/dispensing slot for receiving currency and a projecting hollow tongue forward of the casing. The forward-extending hollow tongue accommodates at least a portion of the data reception assembly. The bezel assembly can include a wireless communication function that is communicably connectable with a mobile device via a wireless communication method, a manual entry function, a biometric reader, one or more cameras for scanning and decrypting 2D barcodes and the like, thus enhancing the overall functionality of the financial transactional device.

A cast exhaust manifold for an engine is disclosed that is fastened to the engine by a number of independent flanges between each pair of which a spacer is positioned to produce an interference fit when the exhaust manifold is at ambient temperature. The use of independent flanges allow the exhaust manifold to expand when heated without creating high levels of internal stress and the spacers prevent undue distortion of the exhaust manifold when the exhaust manifold cools.

Embodiments for methods, systems, apparatuses for an enterprise application providing user control of sharing of data between multiple Enterprise Resource Planning (ERP) systems are disclosed. One method includes identifying types of shared data between the multiple ERPs, conveying the identified shared data types to a user, allowing the user to selectively load shared data to a parent realm based on the identified types of shared data, allowing the user to selectively indicate which data is not to be shared between ERPs to identified child realms, and providing sharing of shared data between child realms.

A digital disc interface for a plurality of audio-video streams produced from multiple recordings of an event is described. The video recordings include a primary audio-video recording, as well as one or more participant audio-video recordings. The interface provides time-synchronized rendering of a composite video image of the various video streams, including a main full-size rendering of one video stream, the accompanying audio stream, and miniaturized versions of participant streams. Using a video menu-driven interface, the consumer is able to simultaneously monitor the streams, and when desired, to navigate among the various video streams and select an alternative audio-video stream for full-size rendering and an accompanying audio stream.
