Patent number: 11928740Abstract: A multivariate predictive system processes usage based data that includes a database engine that provides access to a plurality of database management systems that mine diverse sources of usage based data. A digital filter selectively filters data streams that include usage based data. A sampler automatically divides the filtered data into sample groups and stores the sample groups in a memory. The sampler divides the filtered data according to insurance rating variables processed by a processor programmed to underwrite an insurance product and rate that insurance product. Some samplers store the divided filter data in a local memory. A multiplier multiples rating factors preprogrammed with the insurance rating variables with a base rate of insurance to determine an insured's insurance premium.Type: GrantFiled: October 6, 2021Date of Patent: March 12, 2024Assignee: PROGRESSIVE CASUALTY INSURANCE COMPANYInventors: Richard Hutchinson, William Everett, David Pratt, Raymond Ling

Publication number: 20210365471Abstract: The present disclosure involves systems, software, and computer implemented methods for generating insights based on numeric and categorical data. One example method includes receiving a request for an insight analysis for a dataset that includes at least one continuous feature and at least one categorical feature. Continuous features can have any value within a range of numerical values and categorical features are enumerated features that can have a value from a predefined set of values. A selection of a first continuous feature for analysis is received, and at least one categorical feature is identified for analysis. A deviation factor and a relationship factor are determined for each identified categorical feature. An insight score is determined for each identified categorical feature that combines the deviation factor and the relationship factor for the categorical feature. The insight score is provided for at least some of the identified categorical features.Type: ApplicationFiled: May 19, 2020Publication date: November 25, 2021Inventors: Paul O'Hara, Robert McGrath, Ying Wu, Shekhar Chhabra, Eoin Goslin, Pat Connaughton, John Bowden, Alan Maher, David Hutchinson, Leanne Long, Malte Christian Kaufmann, Pukhraj Saxena, Priti Mulchandani, Anirban Banerjee

Patent number: 9182428Abstract: A circuit may sense the differential voltage across two nodes that each have a non-zero common mode voltage. The circuit may have a positive input impedance that is imposed across the nodes. An impedance compensation circuit may generate a compensation current that is delivered to the nodes that substantially cancels the loading effect of the positive input impedance. The impedance compensation circuit may generate a negative input impedance that is imposed across the two nodes that is substantially the same as the positive input impedance. The impedance compensation circuit may instead be configured to deliver the compensation current to the nodes.Type: GrantFiled: April 26, 2012Date of Patent: November 10, 2015Assignee: LINEAR TECHNOLOGY CORPORATIONInventors: Michael Alfred Kultgen, David Hutchinson

Publication number: 20130212574Abstract: A sub-device agent running on a network device provides tools for detecting and managing sub-devices connected to the network device. The sub-device agent reports the presence of the sub-devices to a configuration manager, which provides a user interface for managing the sub-devices. The sub-devices are not directly detectable by or visible to the configuration manager. The sub-device agent provides access to the sub-devices for monitoring, configuring, updating, etc. The sub-device agent may be used to install or upgrade firmware or software on the sub-device or to monitor a status of the sub-device. Sub-device modules, such as OEM plug-ins and drivers, may be used by the sub-device agent to discover and manage the sub-devices.Type: ApplicationFiled: February 14, 2012Publication date: August 15, 2013Applicant: MICROSOFT CORPORATIONInventors: Jonathan David Hutchinson, Douglas Graham King, Ziad Elmalki, Rinku Sreedhar

Patent number: 8468294Abstract: A memory system and methods of its operation are presented. The memory system includes a controller and a non-volatile memory circuit, where the non-volatile memory circuit has a first section, where data is stored in a binary format, and a second section, where data is stored in a multi-state format. The memory system receives data from the host and performs a binary write operation of the received data to the first section of the non-volatile memory circuit. The memory system subsequently folds portions of the data from the first section of the non-volatile memory to the second section of the non-volatile memory, wherein a folding operation includes reading the portions of the data from the first section rewriting it into the second section of the non-volatile memory using a multi-state programming operation. The controller determines to operate the memory system according to one of multiple modes.Type: GrantFiled: December 18, 2009Date of Patent: June 18, 2013Assignee: SanDisk Technologies Inc.Inventors: Jianmin Huang, Chris Avila, Lee M.

Patent number: 8144512Abstract: A memory system and methods of its operation are presented. The memory system includes a volatile buffer memory and a non-volatile memory circuit, where the non-volatile memory circuit has a first section, where data is stored in a binary format, and a second section, where data is stored in a multi-state format. When writing data to the non-volatile memory, the data is received from a host, stored in the buffer memory, transferred from the buffer memory to into read/write registers of the non-volatile memory circuit, and then written from the read/write registers to the first section of the non-volatile memory circuit using a binary write operation.Type: GrantFiled: December 18, 2009Date of Patent: March 27, 2012Assignee: SanDisk Technologies Inc.Inventors: Jianmin Huang, Chris Avila, Lee M.
