A photographic plate holder for use in holography is disclosed. The plate holder includes apparatus for precise repositioning of the photographic plate after it has been removed for processing of a hologram recorded thereon. The photographic plate is retained in a plate carriage which in turn is removably supported in a kinematically stable mount on an adjustable member. The adjustable member is disposed upon a support member by a spring suspension system and is adjustable along X and Y-axes by ...

The present invention is an optical probe for emission of light from a region smaller than a wavelength. The optical probe includes a transmission line fed by an optic fiber and an impedance matched coupling. In a first embodiment the optical probe ends with a surface-wave transmission line including a central conductor and a coaxial dielectric. The diameter of the central conductor at the optic fiber is selected to substantially match the transmission impedance of the surface-wave transmission ...

A pneumatically-powered battering ram for striking objects quickly and effectively with an initial high striking velocity resulting in an increased peak force effective in breaking the target object. The battering ram includes an elongated hollow housing containing a mass to be propelled, preferably a piston, and a supply of compressed gas, preferably carbon dioxide disposed within the housing. A valve mechanism releases a portion of the compressed gas into a charge cavity located between the pi...

Calling name presentation services are provided by maintaining a local cache of requested information. When a called destination is determined to subscribe to calling name presentation, the local cache is queried to determine if the calling number is in the local cache. If the calling number is in the local cache, information corresponding to the calling number is retrieved from the local cache. If the calling number is not in the local cache, a remote database is queried for the information. Th...

A method and system for conveying supervision information to a call processing system using an intelligent network is provided. A call originating at the call processing system is received by a network switch. The network switch sends a query to a service control point which returns a routing message to the network switch. The network switch routes the call and waits for supervision information corresponding to a request for subsequent information provided by the service control point. Upon rece...

An improved punctum plug is more easily visualized when positioned within a punctual canal of a recipient. The body of the plug features an outwardly exposed surface when properly positioned, and a substance causing at least the outwardly exposed surface to contrast with surrounding tissue, such that the use of the substance causes the plug to be more easily visualized than if the substance were not present. The substance, which may be disposed on the outwardly exposed surface or within the body...

A method and system for routing a call incoming to a Private Branch Exchange (PBX) network telephone number from outside of the PBX network based on a PBX subscriber's location includes routing the call to a wireline switch which detects predetermined PBX triggers. Also included is generating a query at the switch for receipt by the wireline service control point (SCP) upon detecting the PBX triggers. The query requests mobile registration status data which corresponds to the PBX number. Also in...

A secured partitioned communication system includes a shared switch network system in communication with an Intelligent Network Processor (INP). A terminating Intelligent Communication Device (ICD) located outside the management and control of the network defines a boundary therebetween and permits multiple inter-dependant parts of the communication service to be distributed to increase functionality without modifying an existing network switch.

Described herein are various embodiments of an apparatus, system and method for operating a dual fueled spark ignition engine. For example, according to one illustrative embodiment, a method for operating a dual fueled spark ignition engine includes fueling the engine solely with a combustion promoter within a first engine load range between zero and an engine load associated with a target combustion condition selected from the group consisting of rough limit, knock limit, and any of various con...
