Patent number: 6434617Abstract: The invention enables an application program to communicate a message over a network without having information regarding a protocol employed by the network. A network library program, running independently of the application program, stores communication protocol data and procedures for establishing message transport data structures to be used in communicating over the network. Initially, the application program passes an address string to the network library program. In response, the network library program determines a network protocol to be used by analyzing the received address string. The network library program then creates a “transport address” data structure which records both the protocol and the address string. The network library program further establishes a “transport” data structure for the specific message type to be dispatched, which data structure includes a dispatch command and a socket handle to be used during the transmission.Type: GrantFiled: February 22, 1999Date of Patent: August 13, 2002Assignee: Hewlett-Packard Co.Inventors: James Clough, Craig R.

Patent number: 6426836Abstract: A projection surface includes scattering microparticles that are in constant motion in relation to each other and to a source of laser radiation in a laser projection system. The microparticles reduce the formation of spots that normally occur when viewing the contents of images which are uniformly illuminated by means of laser projection and which are reflected off a projection surface. The microparticles are reflective in a suspension fluid and move due to Brownian molecular motion. A mirror is placed on the back wall of the screen so that the viewer sees both the backscattered light from the incident beam as well as the forward scattered light from the reflected beam. A cellular structure is located in the suspension fluid to laterally confine the scattered light increasing the sharpness of the laser light seen by the viewer.Type: GrantFiled: January 31, 2001Date of Patent: July 30, 2002Assignee: Hewlett-Packard Co.Inventors: Andreas Dorsel, Frank Diedrich
