Application server with a protocol-neutral programming model for developing telecommunications-based applications
An application server is described for development of telecommunications-based software applications. The application server provides a protocol-neutral programming model for application developers. Rather than having to account for specific protocol entry points into the server, all interactions in the server are abstracted as asynchronous events through the event broker layer. State management and concurrency are implemented as an actor-based model, where each actor owns its own segment of state and other actors wishing to update that state send asynchronous events to the owner. Thus, any communication in the various protocols can be expressed as an asynchronous event passed to, from and between the actors, who are each responsible for maintaining their own segment of state locally. This architecture allows multiple protocols to be consumed in one process, allow applications sessions to span multiple environments and protocols, and allows the programming model to be decoupled from any particular protocol entry point.

The guaranteed base interest rate is set at the beginning of the guarantee period, which is credited to an account for an initial pre-defined period. Periodically, the then-current referenced rate is compared to a base referenced rate defined at the establishment of the guarantee period. If the referenced rate has increased, the interest rate that will be credited to the account value will increase by an amount that is based on the amount of increase in the referenced rate. If the referenced rate has not changed or has decreased, the interest rate that will be credited to the account value will be the guaranteed base interest rate.

Apparatus for enhancing the dynamic range of shockline-based sampling receivers
Shockline-based samplers of a vector-network analyzer (VNA) have enhanced dynamic range by using a dynamic bias network applied to the non-linear transmission lines (NLTLs) or shocklines. The bias voltage applied to the NLTL provides direct control over the falling-edge shockline compression, and thus the insertion loss and overall RF bandwidth of the sampler. Alternating between a forward bias voltage to turn off a shockline sampler when it is not needed and thereby reducing spurious generation and improving isolation can be alternatively applied with a reverse bias voltage to turn on the shockline sampler in a normal operation mode. By measuring the shockline output and providing feedback in the reverse-bias mode, the bias voltage can be dynamically adjusted to significantly increase the performance of the NLTL based sampler. In the presence of a strong positive bias voltage, the incoming LO and its harmonics experience large ohmic losses thus preventing gating pulses from forming in the shockline. The ohmic losses enable strong isolation between the LO sampling channels and will increase spectral purity at the VNA test ports.

A wave division multiplexing (WDM) system is disclosed which accommodates shifts in the resonant frequency of optical modulators by using at least two carriers per optical communications channel and at least two resonant modulator circuits respectively associated with the carriers within each optical modulator. A first resonant modulator circuit resonates with a first carrier and a second resonates with a second carrier when there is a shift in resonance frequency of the at least two resonant optical modulator circuits. A switch circuit controls which carrier is being modulated by its respective resonant modulator circuit.
View finder and camera
The view finder includes an observation optical system for enlarged observation of information displayed on a display section. The observation optical system includes an optical path bending member for bending the optical path. The view finder is configured such that an angle formed between a principal ray of a maximum angle of view and the display section is in the range of 90±5 degrees.
