Patent number: 10917311Abstract: A method and apparatus (e.g., network test instrument) for presenting network device diagnostic information in which a listing of network devices discovered via a first network connection (e.g., wirelessly—802.11) to a test network is presented in a GUI of a network diagnostic instrument. Acquired network diagnostic information for a network device selected from the listing of network devices is then presented in the GUI wherein the presented network diagnostic information is acquired via the first network connection (e.g., wirelessly—802.11). Indication (and a link thereto) is provided in the GUI indicating network diagnostic information for the selected network device was also acquired via a second network connection to the test network (e.g., via a wired connection—802.3).Type: GrantFiled: May 23, 2017Date of Patent: February 9, 2021Assignee: NetAlly, LLCInventors: James A.

Patent number: 9473381Abstract: A apparatus for network testing includes a network port adapted to receive data from the test network and one or more network interfaces of a wireless access point in operative communication with the network port. The one or more network interfaces generates a wireless local area network (WLAN) that communicates diagnostic information of the test network to a client device and causes the client device to display the diagnostic information.Type: GrantFiled: March 8, 2013Date of Patent: October 18, 2016Assignee: AirMagnet, Inc.Inventor: James Kahkoska

Publication number: 20150006982Abstract: An apparatus for network testing receives data from a test network, validates, via a physical layer controller (PHY), a link to the test network based on the received data. A rate of the received data is throttled from the test network to a lower rate in response to a first condition. The received data is then processed at the lower rate via a media access controller (MAC).Type: ApplicationFiled: July 1, 2013Publication date: January 1, 2015Inventor: James A. Kahkoska

Patent number: 8873433Abstract: A network test tool can determine if it is linked to directly to an indicated managed device or an intermediate unmanaged device. Discovery protocols and spanning tree are designed to map network topology and eliminate closed loops in networks. As such these management packets are among the first emerging from managed switches immediately upon acquiring a new link. By analyzing the first few packets, with timeouts, the tool can determine with a high degree of accuracy if it is really connected to the advertised nearest switch. If an unmanaged switch exists between the managed switch and tool, the managed switch will not detect the link event therefore not immediately send discovery packets. Once the tool determines it is not linked to the managed switch, further packet analysis can indicated if the intermediate device is a Layer 2 switch or Hub.Type: GrantFiled: June 28, 2011Date of Patent: October 28, 2014Assignee: Fluke CorporationInventor: James A.

Publication number: 20060206268Abstract: A lightning detector system monitors the lightning strikes requires a real-time detection and processing system. A real-time processing system requires the use of a high-speed processor with floating-point math capability and multiple analog to digital channels. The cost, power and size requirements of such a system make it difficult to develop a low cost, pocket size lightning detector with long battery life. This invention provides a method of detecting and ranging lightning strikes using an inexpensive eight-bit processor with a single A/D channel and without floating point hardware.Type: ApplicationFiled: March 10, 2006Publication date: September 14, 2006Inventor: James Kahkoska

Patent number: 6002671Abstract: A method of testing ADSL (asymmetric digital subscriber line) circuits is provided. A test instrument is connected to the customer premises end of the ADSL circuit, consisting of an ATU-C modem on the central office end and an ATU-R modem on the customer premises end, with a twisted-pair telephone line connecting the ATU-R and ATU-C modems. A remote test instrument is coupled to the ATU-C modem, typically on a semi-permanent basis in the central office, dedicated for testing multiple ADSL circuits by communicating with multiple ATU-C modems via a switch or router. The test instrument and remote test instrument communicate with each other in full duplex via the ADSL circuit using Internet Protocol (IP) data packets. The test instrument generates the upstream data traffic, controls the test sequence, and controls and coordinates the throughput test with the remote test instrument.Type: GrantFiled: September 3, 1997Date of Patent: December 14, 1999Assignee: Fluke CorporationInventors: James Kahkoska, Bruce James Kosbab

Patent number: 5919248Abstract: In a test instrument for testing LANs, a method for determining network health is provided. Network health is a composite indicator of the condition of the LAN that is based on a system of rules that take into account both percent utilization and percent collisions to provide for easier interpretation by a test instrument user. The test instrument is coupled to a LAN to receive the link pulse and establish communications. The test instrument receives data traffic from the LAN in the form of frames which are analyzed to produce network information which include the network parameters of percent utilization and percent collisions. Decisions about the network health based are reached by mapping a plurality of network parameters to a decision matrix that is constructed from expert knowledge in the field of local area networks.Type: GrantFiled: March 25, 1997Date of Patent: July 6, 1999Assignee: Fluke CorporationInventors: James Kahkoska, David G.

Patent number: 5396582Abstract: A system and method for converting raster data in a memory plane to a vector number number such as a plotter. The method with copying the raster data into a working copy and then at a predetermined bit in the memory plane sequentially scans each bit to ascertain the presence of first or second states. The first state corresponds to the illumination of a corresponding pixel in the display monitor and the second state corresponding to a pixel which is not illuminated. When the first state is sensed, all vectors having beginning X,Y coordinates corresponding to the X,Y coordinate of the bit are identified. When more than one vector is identified, only one of the identified vectors is selected according to a priority scheme. All of the bits in the working copy corresponding to the selected vector are erased. The beginning X,Y coordinate and the ending X,Y coordinate of the selected vector form the vector output.Type: GrantFiled: June 28, 1993Date of Patent: March 7, 1995Assignee: Hewlett-Packard CompanyInventor: James Kahkoska

Patent number: 5204600Abstract: An apparatus and method for simulating a mechanical detent in a manually operable rotary digital encoder typically used to control a display or readout in an associated electronic system. The output from the encoder to the electronic system is suspended for a predetermined time when the encoder shaft is rotated past a predetermined preset point. While the encoder output is suspended, the output signal V.sub.o to the electronic system is set at a level indicative of the preset point. The system user is thus able to quickly locate the preset point without overshooting it. If the user does, in fact, want to adjust the encoder past the preset point, the delay is of such a duration that it will have expired by the time the user repositions his hand on the encoder knob, thus allowing adjustment of the encoder to continue beyond the preset point.Type: GrantFiled: February 6, 1991Date of Patent: April 20, 1993Assignee: Hewlett-Packard CompanyInventor: James Kahkoska
