Patent number: 8451979Abstract: A system for correlating a subscriber unit to a physical port in a point to multipoint wire line network is disclosed. An installer is prompted to manually input a location code associated with the subscriber. The location code in the subscriber unit is received, and is transmitted via the network to a central repository. The location code is stored in the central repository toward associating the location code with the physical port.Type: GrantFiled: June 4, 2001Date of Patent: May 28, 2013Assignee: Calix, Inc.Inventors: Robert M. Lund, Chris D. Koch, Milton J. Johnson, Joel K. Lagerquist, Daniel R. Oelke, Jeffrey T. Kays, Joseph J. Knudsen, Steven J. Talus

Patent number: 7525980Abstract: Assignment of network addresses, e.g., IP addresses, to network nodes in a passive optical network (PON) may involve assignment of IP addresses within a common subnet scope to network nodes coupled to different optical fiber links and different interface modules in the PON. In this manner, excessive waste of IP addresses can be avoided. Instead of assigning an entire subnet scope of addresses to the nodes coupled to a single optical fiber link, a common subnet can be allocated across a PON having multiple, independent interfaces, increasing the number of subnet IP addresses that are actually used. Accordingly, the IP address space within a subnet scope can be distributed more efficiently. In addition to conserving IP addresses, the number of subnets allocated by ISPs can be reduced, along with the significant expense incurred by ISPs in reserving and maintaining multiple class C subnets.Type: GrantFiled: August 3, 2004Date of Patent: April 28, 2009Assignee: Calix Networks, Inc.Inventors: Christopher D Koch, Milton J Johnson

Publication number: 20040042446Abstract: In general, the disclosure presents techniques for creating and maintaining routing information within a passive optical network. A PON interface receives a DHCP request to obtain a network address from a client represented by a node. The PON interface maps a particular interface module on which the client resides to unique client information, e.g., a media access control (MAC) address or other identifier, included in the DHCP request. The PON interface forwards the request to a DHCP server that returns a DHCP response indicating an administered IP address and lease time for the requesting client. Upon receipt of the DHCP response, the PON interface updates the mapping to create routing information for routing packets to the administered addresses. For example, PON interface may map the administered IP address to the particular interface module on which the client resides.Type: ApplicationFiled: May 30, 2003Publication date: March 4, 2004Inventors: Christopher D.

Publication number: 20040033075Abstract: An interface module of a Passive Optical Network (PON) maintains information associating Class-D Internet Protocol (IP) addresses for multicast streams with Asynchronous Transfer Mode (ATM) Virtual Circuit Channels (VCCs), and with nodes of the PON that have requested the multicast streams. When an interface module receives a first request for a multicast stream, it will associate a VCC and the requesting node with a Class-D IP address of the stream and deliver the stream on the associated VCC. The interface module may periodically deliver map packets to nodes to indicate the current Class-D IP to VCC mappings, and subsequent requesting nodes may obtain the stream by referring to the map packet. The interface module deletes the association of a node with a stream when it receives a disassociation request from the node, and delivers the stream on the associated VCC so long as any node is associated with the stream.Type: ApplicationFiled: May 30, 2003Publication date: February 19, 2004Inventors: Christopher D.

Patent number: 5467502Abstract: An upright vacuum cleaner including a canister assembly pivotally connected to a nozzle assembly and an extensible hose which forms part of the vacuum path between the nozzle assembly and the canister assembly and which can be disconnected from the nozzle assembly for above-the-floor cleaning. Disconnecting the hose deenergizes an agitator motor in the nozzle assembly. The canister assembly includes a housing with an integral hand tool and attachment storage area which retains the tools and attachments, as well as the extensible hose, within the periphery of the housing. The upright vacuum cleaner also includes a height adjustment mechanism which deenergizes the agitator motor when the nozzle assembly is in its closest relation to the floor surface being cleaned.Type: GrantFiled: March 2, 1994Date of Patent: November 21, 1995Assignee: Matsushita Applicane CorporationInventors: Milton J. Johnson, Jeffrey T. Roney

Patent number: 4279198Abstract: A refuse compactor slide bearing for use in guiding the movement of the compactor ram along suitable guides to and from a compacting position within the compactor. The slide bearings are formed as one-piece elements having angularly related slide portions for slidably engaging corresponding angularly related portions of the ram guide means. The bearing slide portions may be formed as tongues resiliently connected to a base portion of the bearing by resilient connecting portions. The tongues are arranged to extend in a direction parallel to that defined by movement of the ram. The tongues may have different slide surface areas and configurations coordinated with the force transfer requirements. One of the slide portions includes a third tongue extending in the direction of movement of the ram toward the compacting position. Cooperating snap fastening means may be provided on the bearing on the ram assembly.Type: GrantFiled: November 26, 1979Date of Patent: July 21, 1981Assignee: Whirlpool CorporationInventor: Milton J.

Patent number: 4068575Abstract: A selective spray device for use in a refuse compactor, or the like, arranged to provide selectively onto the refuse a deodorizing spray. The device includes a control for effecting automatically a spray of the refuse as an incident of movement of the receptacle into which the refuse is placed for compaction. A manually operable control permits a manual operation of the spray device when desired at any time. The control may further be arranged to prevent operation of the spray device notwithstanding movement of the receptacle. The spray may be provided as a pressurized fluid in a can having a suitable selectively operable valve. The valve actuator may be held fixed while the can itself is displaced to effect an opening of the valve. The control may include a slidable cam having associated therewith a manually operable handle. The selective opening of the valve may be effected by a lever pivotally mounted adjacent the cam and having a cam follower engaged by the cam.Type: GrantFiled: August 24, 1976Date of Patent: January 17, 1978Assignee: Whirlpool CorporationInventors: Charles R. Difley, Milton J. Johnson, William R. McDonald
