In an embodiment, the device also includes a completely-in-canal (CIC) component, shaped to fit into the ear canal of the user such that it touches the bony portion of the ear canal. In some embodiments, the CIC component includes either a universal fit or a custom fit ear mold. The custom fit ear mold can be fabricated using a rapid prototyping technology, in which the contours of the user's ear canal are scanned, and the scan data is used either directly or indirectly to replicate the ear canal contours of that user into the custom fit ear mold. In some embodiments, the ear mold is detachably interconnected with a speaker module, preferably using either an intermediate sleeve or a detachable locking pin assembly. In another embodiment, the speaker module is permanently encapsulated within the ear mold.

In representative embodiments, the present invention is directed to an at least partially in-the-canal module. The module may include a speaker module that generates audio signals from an electrical driving signal. The speaker module has a tubular body with a diameter that is smaller than the ear canal of the user. The speaker module also includes an arcuate raised ridge. A cushion tip of deformable material may be used to enclose the speaker module within a tubular portion that applies an elastic force to the arcuate raised ridge to prevent removal of the speaker from the cushion tip. Also, the tubular portion is longer than the speaker module to cause the cushion tip to deflect during navigation through the canal. Further, the tip portion of the cushion tip possesses sufficient structural rigidity to prevent the speaker from being pushed through the cushion tip during navigation through the canal.

A customer information control system (CICS) application programming interface (API), with transient data queue functions, in a loosely coupled data processing environment. In accordance with the purpose of the invention, as embodied and broadly described herein, the invention is directed to a method, system and computer readable medium including program instructions (hereafter collectively referred to as the "invention"). In particular, the invention includes implementing a loosely coupled CICS region in a data processing environment, the loosely coupled CICS region including at least two of a plurality of address spaces each of which being associated with a machine. The invention further includes providing at least one CICS-API operating system server (COSS) within the loosely coupled CICS region, each COSS operating in one of the at least two address spaces within the loosely coupled CICS region.

Consequently, there is no affinity between the address space in which each COSS is operating and the address space being occupied by the transient data queue. Moreover, the information resource is shared by each COSS.

According to the invention, a hearing instrument comprising at least one inner microphone operable to determine a sensing signal representative of an acoustic signal at a position in front of the user's eardrum—which may be an acoustic signal at a position between an ITE (or ITC or CIC) hearing instrument and the eardrum or between an earpiece and the eardrum—is used. In accordance with the invention, in front of the eardrum an acoustic signal is produced. The inner microphone creates a sensing signal representative of the acoustic signal, and the signal processing unit of the hearing instrument determines a characteristic of the user's ear canal based thereon and memorizes values indicative of the characteristic. According to a preferred embodiment, the characteristic is an acoustic coupling transfer characteristic, which is determined based on a comparison of a signal representative of the output signal of the signal processing unit's digital signal processing stage and the sensing signal. In contrast to the state of the art, no control loop is necessary to adapt the gain to the ear canal characteristic, but the memorized values may be used therefor.

The present invention is directed to a system for for automated interface generation for computer programs operating in different environments. The system comprises a utility which imports a CICS COBOL transaction source file, parses the communication area of the CICS file, and generates modelling information. The modelling information represents the nature and structure of data in the CICS transaction source file, and is written to a persistent data store. The utility uses the information in the persistent data store to generate an application programming interface. The application programming interface takes the data values from the other language and translates them to a formatted CICS COBOL communications area. This format is derived from the definition of the CICS communications area contained in the imported CICS program. After the translation runs, the resulting CICS COBOL communications area is translated back to the data values of the other language. This translation step also handles the data conversion between different codepages and machine architectures and program semantics. The resulting language values represent the result of the transaction. The CICS transaction is accessed using the CICS External Call Interface mechanism.

A routing node for receiving, processing, and subsequently transmitting Signaling System 7 (SS7) signaling messages destined for a Media Gateway Controller (MGC) type network element is disclosed. A Circuit Identification Code (CIC) routing node is adapted to receive an ISUP message from an associated SS7 network and determine the routing destination of the message based, at least in part, on a CIC parameter value contained within the message. The ISUP message is subsequently encapsulated in an Internet Protocol (IP) envelope and transmitted to a destination node via an IP communication link. Such a CIC routing node also provides network service providers with a method of generally eliminating the need for the assignment of unique SS7 network point codes to each MGC node in a network. That is, a CIC routing node allows multiple MGC nodes to effectively correspond to a single SS7 network point code.

A cascaded sigma-delta modulator has several modulator loops that have one or two sets of integrators, summers, and scalers, and a quantizer that generates a loop output. Input muxes to each loop select either an overall input or the loop output from a prior loop, allowing the modulator loops to be cascaded in series or to operate separately. Filter-configuring muxes after each modulator loop select either that loop's output or a loop output from any prior loop, or a zero. Each filter-configuring mux drives an input to a modified CIC filter. The modified CIC filter has an initial delay stage that receives the first filter-configuring mux output, and successive integrator stages that each receives a successive filter-configuring mux output. The modified CIC filter is a combination of a digital transform filter and a Cascaded-Integrator-Comb (CIC) filter. Modulator loops are powered down for lower-performance configurations or cascaded together for higher-performance configurations.
