Publication number: 20240171416Abstract: Devices, systems and methods are provided for low-power and high-sampling rate of analog signals received from sensors transported by host devices. The devices, systems and methods may be adapted to utilize GPS and PPS signals for synchronization with digitized signals generated based on the sampling of the analog signals that are simultaneously received and processed by multiple channels. Synchronized data packets may be recorded by the disclosed data acquisition systems, and may be further transmitted to host devices and remote devices.Type: ApplicationFiled: November 15, 2023Publication date: May 23, 2024Applicant: The United States of America as represented by the Secretary of the NavyInventors: Mark E Paulus, Daniel A Gentile, Kevin D Jones, Kyler D Callahan, Paul R Leary, Vladimir N Dobrokhodov, Kevin B Smith

Publication number: 20240078386Abstract: Methods, apparatuses, and systems are presented for generating natural language models using a novel system architecture for feature extraction. A method for extracting features for natural language processing comprises: accessing one or more tokens generated from a document to be processed; receiving one or more feature types defined by user; receiving selection of one or more feature types from a plurality of system-defined and user-defined feature types, wherein each feature type comprises one or more rules for generating features; receiving one or more parameters for the selected feature types, wherein the one or more rules for generating features are defined at least in part by the parameters; generating features associated with the document to be processed based on the selected feature types and the received parameters; and outputting the generated features in a format common among all feature types.Type: ApplicationFiled: November 2, 2023Publication date: March 7, 2024Applicant: 100.co Global Holdings, LLCInventors: Robert J. Munro, Schuyler D. Erle, Tyler J. Schnoebelen, Brendan D. Callahan, Jessica D. Long, Gary C. King, Paul A. Tepper, Jason A. Brenier, Stefan Krawczyk

Patent number: 8345643Abstract: A client device detects when it roams between subnets and signals to a device in the subnet being entered. The client may detect roaming by monitoring subnet identifiers included in beacon signals transmitted by access points. When the client detects a beacon with a new subnet identifier and at the same time no longer detects a beacon with the original subnet identifier then roaming is indicated. When roaming is indicated the client responds by setting a tag, such as an IEEE 802.1q VLAN tag, in packets transmitted by the client. The tagged packets provide an indication to devices in the new subnet that the client has roamed into that new subnet. Devices in the new subnet, such as access points and switches, recognize the tagged packets and establish a path to the original subnet in response. For example, the tagged packets transmitted by the client may be encapsulated pursuant to a Layer 3 protocol and tunneled from a switch associated with the subnet being entered to a switch in the original subnet.Type: GrantFiled: February 3, 2005Date of Patent: January 1, 2013Assignee: Piccata Fund Limited Liability CompanyInventors: Floyd Backes, Paul D. Callahan, Gary Vacon

Patent number: 7970408Abstract: An access point in a wireless network includes an external indication of the access point's proximity to another access point. The external indication can be a LED that blinks at a rate that is related to the proximity of the access point to the other access point. An access point is also capable of producing a network map that indicates the access point's proximity relative to other access points that are coupled to the network. The access point is further capable of monitoring wireless network traffic to ascertain whether wireless network traffic has exceeded a threshold, and if so, releasing some client devices so that wireless network traffic no longer exceeds the threshold. The access point is also capable of automatically choosing one of a plurality of radio frequencies on which to operate. The access point chooses a frequency after evaluating frequencies on which other access points may be operating.Type: GrantFiled: September 9, 2009Date of Patent: June 28, 2011Assignee: Autocell Laboratories, Inc.Inventors: Gary Vacon, Paul D.

Patent number: 7849225Abstract: A system, device, and method for managing communication services in an optical communication system utilizes a optical service agent (OSA) that operates within the domain of the network user and manages various communication services on behalf of the network user. The OSA interacts with the optical communication network to obtain various communication services and manages those communication services for the network user based upon predetermined parameters defined by the network user. An authenticated auto-discovery mechanism is used to automatically identify and authenticate OSA-enabled users and to distribute information between peer OSA-enabled users. A peer-to-peer signaling mechanism is used to extend OSA functionality to OSA-enabled users that do not interface directly with the optical communication network.Type: GrantFiled: August 15, 2001Date of Patent: December 7, 2010Assignee: Ciena CorporationInventors: Bruce A. Schofield, William R. Hawe, Paul D. Callahan, Indermohan S. Monga, Stephen Suryaputra, Andre N. Fredette

Patent number: 7774028Abstract: A system for providing multiple graphical representations for wireless network devices indicating status of the devices. The generated graphical representations of the devices are indicative of radio frequency channels the devices are operating on, as well as whether devices are on, off or in a standby mode. A device in standby mode monitors the wireless network to determine when it can resume normal operation. A menu or other interface construct is generated to enable a user to determine additional properties of the devices, such as addresses. Device representations may also indicate that devices are operating within the wireless network, but do not support one or more functions associated the system for managing the wireless network.Type: GrantFiled: May 27, 2004Date of Patent: August 10, 2010Assignee: Autocell Laboratories, Inc.Inventors: Roger Pfister, Floyd Backes, Paul D.

Patent number: 7636576Abstract: A previously unknown wireless device, which may be either an access point or a station, is detected by receipt of transmissions from that device at one or more access points that are currently operating within a managed wireless network. A graphic representation of the newly detected device is displayed in a region of a user interface external to a region containing a representation of the physical environment of the managed wireless network. A user selects a number of known access points from which an estimated distance to the newly detected device is to be determined and represented. A representation is generated of an estimated distance from each one of the selected number of access points, such as those access points that are estimated to be physically closest to the newly detected device, for example on the basis of signal strength with regard to transmissions from the newly detected device received at the known access points.Type: GrantFiled: April 11, 2006Date of Patent: December 22, 2009Assignee: Autocell Laboratories, Inc.Inventors: Roger Pfister, Floyd Backes, Paul D.

Patent number: 7283848Abstract: A system and method for generating display objects representing areas of radio coverage, available bandwidth and channel selection for wireless devices in a wireless communication network are disclosed. Substantially circular rings are provided defining areas of radio coverage for corresponding wireless network devices. The rings are super-imposed over a representation of the physical environment in which the wireless network is deployed. The thickness of the generated rings is representative of the amount of throughput available within the rings. A relatively thicker ring indicates that throughput within the ring is relatively high, while a relatively thin ring indicates that throughput within the ring is relatively low. The rings are further indicative of the current radio channel selected for operation by the associated device. Different colors may be associated with different channels, so that all devices using the same channel have the same color rings.Type: GrantFiled: May 27, 2004Date of Patent: October 16, 2007Assignee: Autocell Laboratories, Inc.Inventors: Roger Pfister, Paul D.
