Publication number: 20200034351Abstract: Systems and methods are disclosed and include a node storing a local table and a control module that collects heterogeneous sensor data, tracks objects in an environment of the node, and converts the heterogeneous sensor data into time series data. An object-relational mapping module formats the time series data for direct compatibility to data in a master database of a cloud-based server. A correlation module further formats the time series data to provide resultant data in a single format commonly used by multiple map sources. A first primitive extraction module extracts primitives from the resultant data. An edge computing module generates a first table of data corresponding to the primitives and compatible with a master table of the master database, detects a changed primitive, uploads the changed primitive to the cloud-based server, receives updated data based on the changed primitive, and updates the local table based on the updated data.Type: ApplicationFiled: June 26, 2019Publication date: January 30, 2020Inventors: Kazuoki MATSUGATANI, Zhiyuan DU, Joseph LULL, Rajesh MALHAN

Patent number: 8036206Abstract: In a commutation system, a data packet is transmitted and received by radio among radio communication apparatuses. In the communication system, the data packet is started to be transmitted on a transmission right acquired on contention type access control in response to a transmission request for the data packet. It is detected that there is a predetermined state in which the transmission request is generated during or after reception of a long packet which is over a given packet length. When the predetermined state is detected, a start timing of the access control is shifted to a timing at which a desired delay time passes after completing reception of the long packet. One example is that an elapse time from a start of reception of the long packet to generation of the transmission request is measured and, as the desired delay time, a period of time calculated by multiplying the measured elapse time by a specified coefficient is set.Type: GrantFiled: July 11, 2008Date of Patent: October 11, 2011Assignee: DENSO CORPORATIONInventors: Masao Matsumoto, Kazuoki Matsugatani

Publication number: 20100198459Abstract: Application data generated by an ECU is wireless transmitted by a transmission device in a subject vehicle so as to periodically change a communications distance by changing, every transmission timing, at least one of (i) a transmission rate, which is used in transforming a transmission packet into a transmission signal in a modulation section, and (ii) a transmission power, which is configured by an amplification section to amplify the transmission signal. As a result, the data transmission from the subject vehicle can be made (i) in high repetition times with respect to a nearby vehicle having a greater risk of collision (i.e., time to collision being shorter), and (ii) in low repetition times with respect to a distant vehicle having a less risk of collision (i.e., time to collision being longer).Type: ApplicationFiled: December 22, 2009Publication date: August 5, 2010Applicant: DENSO CORPORATIONInventors: Jun Kosai, Kazuoki Matsugatani, Shugo Kato, Toshiya Saito

Patent number: 7382737Abstract: Fragment data is generated with respect to a certain data aggregate that is one of a plurality of data aggregates using a coded matrix. The fragment data is capable of restoring the certain data aggregate based on the coded matrix when the fragment data is collected to a required count. The generated fragment data is provided with an identification code associated with the certain data aggregate restored by the fragment data. The fragment data having the identification code is transmitted to a transmission channel. Further, the same transmission channel can be used to transmit the multiple pieces of the fragment data corresponding to the multiple data aggregates. When a receiving party is previously notified of the identification code, it can receive the fragment data by distinguishing which fragment data should restore which data aggregate.Type: GrantFiled: March 12, 2004Date of Patent: June 3, 2008Assignee: Denso CorporationInventors: Kazuoki Matsugatani, Kenji Muto

Patent number: 7145518Abstract: A multiple-frequency common antenna has a first substrate sheet and a second substrate sheet respectively structured by an HIP consisting of a metal plate, small metal plates disposed in two dimensions and linear metal bars connecting these elements. The antenna restricts propagation of surface currents of the first and second frequency bands which are not overlapping with each other. An inverse L-shape antenna and a monopole antenna which are fed with a center conductor and an external conductor of the coaxial line respectively operate as the antenna on the first substrate sheet in the first frequency band and second frequency band. The second substrate sheet does not propagate the radiated wave of the monopole antenna, thereby avoiding unwanted re-radiation.Type: GrantFiled: September 30, 2003Date of Patent: December 5, 2006Assignees: Denso Corporation, Rockwell Scientific CompanyInventors: Makoto Tanaka, Kazuoki Matsugatani, Hao Xin
