Patent number: 8750469Abstract: Systems and methods are described for processing calls. A call is received at a softswitch or other call processing system from a caller intended for a first subscriber. The first call is associated with signaling information, the signaling information including a phone number associated with the caller. A determination is made as to whether the first subscriber has previously received a call associated with the caller phone number at the softswitch. If the first subscriber has not previously received a call associated with the caller phone number at the softswitch, a first message is played to the caller. An indication that the first message was played to the caller is stored in association with an account record associated with the first subscriber.Type: GrantFiled: June 20, 2013Date of Patent: June 10, 2014Assignee: Callwave Communications, LLCInventors: Adrian Van Haaften, David Giannini, Eric Johnson, David F. Hofstatter, David S. Trandal, Robert Duva, Robert F. Smith, John R. Day

Patent number: 8718243Abstract: The present invention relates to telecommunications, and in particular, to systems and processes for processing telephone calls and providing telephony services. In one embodiment, a call processing system, compromises a first telephony interface configured to receive a call from a caller, a storage device configured to store a greeting, and a call answering system. The call answering system is configured to play the greeting in response to receiving the call, record a voice message from the caller, determine when the caller has completed recording the voice message, after determining that the caller has completed recording the voice message, play a prompt regarding the caller becoming a subscriber to call services provided by the call processing system, receive from the caller information used to establish a call services account, and establish a call services account for the caller.Type: GrantFiled: August 29, 2012Date of Patent: May 6, 2014Assignee: Callwave Communications, LLCInventors: David Trandal, Robert Duva, Robert F.

Patent number: 5178918Abstract: Deposition of gold without the use of electric current is described. The system produces thick gold films without the use of strong reducing agents. Discontinuous land areas on high reliability printed wiring boards or ceramic circuits can be readily coated with gold to any desired thickness. Long lead glass-to-metal seals can be uniformly plated without distortion of the leads.Type: GrantFiled: September 13, 1991Date of Patent: January 12, 1993Inventors: Robert Duva, George Ondecker

Patent number: 4470886Abstract: Improved electroplating ternary gold alloy plating baths wherein the gold ingredient is an alkali metal auricyanide, the gold metal being in the plus three oxidation state, and the alloying metals are both cobalt and molybdenum. The electroplating baths also contain citric acid. A wetting agent or surfactant as well as a stress reducer-brightener are also advantageously utilized in the bath. The ternary alloys may be deposited on various electronic and decorative substrates, and the deposits were characterized by unique physical and mechanical properties. Most importantly, there is a substantial improvement in wear resistance. The method of utilizing such improved electroplating baths on various substrates is also described and claimed.Type: GrantFiled: January 4, 1983Date of Patent: September 11, 1984Assignee: OMI International CorporationInventors: Robert Duva, Daniel R.

Patent number: 4401527Abstract: A process for the electrodeposition of palladium in which palladium is electrodeposited from an aqueous plating bath which contains a bath soluble palladium compound, an electrolyte compound and a nitrite compound in an amount sufficient to provide an excess of free nitrite ions relative to the palladium ions. In a preferred embodiment, the bath also contains a buffering agent to maintain the bath pH at from about 6.5 to 7.5. The electrodeposition is carried out using an insoluble anode, while maintaining the excess of free nitrite ions in the bath relative to the palladium ions. In this manner, the plating efficiency of the bath is maintained at a substantially constant, high level for extended periods of plating at current densities in excess of 10 amps per square decimeter.Type: GrantFiled: August 20, 1981Date of Patent: August 30, 1983Assignee: Occidental Chemical CorporationInventors: Robert Duva, Linda J.
