Patent number: 11700787Abstract: An electric walk behind greens mower includes an electric reel motor rotating a cutting reel; an electric traction motor rotating at least one traction drive roller; and an electronic control unit commanding the electric traction motor and the electric reel motor to rotate at reduced speeds during a turn if an electronic signal indicates a deviation from a normal walk speed. The electric walk behind greens mower also may include a battery management system that activates a low voltage power supply if a key switch is turned from the off position to the run position, and that provides a start signal to an electronic control unit if the key switch is momentarily turned from the run position to the start position whereby the electronic control unit activates a high voltage power supply to the electric reel motor and the electric traction motor.Type: GrantFiled: June 11, 2019Date of Patent: July 18, 2023Assignee: Deere & CompanyInventors: Punamchandra Kulkarni, Sandip Edake, Saravanan Deenadayalan, Chinmay Deshpande, Rajesaheb Bagwan, Bhupesh Agrawal, Naveen Kumar

Patent number: 10917385Abstract: A network device includes match filters to be applied to packets transiting two or more network interfaces. In one example, a network device includes a filtering unit configured to apply one or more filters to a first packet transiting a first network interface to determine a first rule the first packet matches, send the first packet and data representing the first network interface to a first accounting filter associated with the first rule, apply the filters to a second packet transiting a second network interface to determine a second rule that the second packet matches, the second packet being different than the first packet, and the second network interface being different than the first network interface, and send the second packet and second data representing the second network interface to a second accounting filter associated with the second rule.Type: GrantFiled: December 29, 2017Date of Patent: February 9, 2021Assignee: Juniper Networks, Inc.Inventors: Shivayogi Ugaji, Robin N.

Publication number: 20190289782Abstract: An electric walk behind greens mower includes an electric reel motor rotating a cutting reel; an electric traction motor rotating at least one traction drive roller; and an electronic control unit commanding the electric traction motor and the electric reel motor to rotate at reduced speeds during a turn if an electronic signal indicates a deviation from a normal walk speed. The electronic control unit also may determine if the actual speed of the electric traction motor is substantially less than the speed specified by a speed lever, and then command the electric reel motor and the electric traction motor to rotate at a lower speed than specified by the speed lever.Type: ApplicationFiled: June 11, 2019Publication date: September 26, 2019Inventors: Punamchandra Kulkarni, Sandip Edake, Saravanan Deenadayalan, Chinmay Deshpande, Rajesaheb Bagwan, Bhupesh Agrawal, Naveen Kumar

Patent number: 8037175Abstract: A network device comprises a service card (e.g., a dynamic flow capture (DFC) service card) executing a communication protocol to receive, from one or more control sources, flow capture information specifying at least one destination and criteria for matching one or more packet flows. The network device includes a network interface card to receive a packet from a network, a packet replication module to replicate the packet, and a control unit to provide the replicated packet from the interface card to the DFC service card. The network device includes a filter cache that caches flow capture information recently received from the CSs. The network device may provide real-time intercept and relaying of specified network-based communications. Moreover, the techniques described herein allow CSs to tap packet flows with little delay after specifying flow capture information, e.g., within 50 milliseconds, even under high-volume networks.Type: GrantFiled: June 24, 2010Date of Patent: October 11, 2011Assignee: Juniper Networks, Inc.Inventors: Manoj Apte, Sandeep Jain, Fritz Budiyanto, Senthil Kumar Duraiswamy, Saravanan Deenadayalan, Yulianto Kokasih Ko

Patent number: 7809827Abstract: A network device comprises a service card (e.g., a lawful intercept (LI) service card) executing a communication protocol to receive, from one or more sources (e.g., law enforcement agents), intercept information specifying at least one destination and criteria for matching one or more packet flows. The network device further includes a network interface card to receive a packet from a network, and a control unit to provide the packet from the interface card to the LI service card. The LI service card executes a flow match detection module that, when the packet matches the criteria of the intercept information, forwards the packet to the destination specified by the intercept information. The network device may provide real-time intercept and relaying of specified network-based communications. Moreover, the techniques described herein allow LEAs to tap packet flows with little delay after specifying intercept information, e.g., within 50 milliseconds, even under high-volume networks.Type: GrantFiled: September 7, 2006Date of Patent: October 5, 2010Assignee: Juniper Networks, Inc.Inventors: Manoj Apte, Sandeep Jain, Fritz Budiyanto, Senthil Kumar Duraiswamy, Saravanan Deenadayalan, Yulianto Kokasih Ko

Patent number: 7633944Abstract: Techniques are described for managing timeouts of filter criteria in a packet flow capture applications. The techniques allow for handling large amounts of timeouts used when monitoring a high volume of packet flows, without placing extreme demands on the operating system for managing the timeouts. The timeout data structure may be a circular array having a plurality of elements. The timeout array represents a span of time and the elements represent sequential units of time. Each element contains one or more pointers. The pointer may point to an entry in the filter table, or may be a null pointer. A timer thread periodically checks the timeout array to determine whether any timeouts occur at the current time. The timer thread checks the element of the array corresponding to the current time by computing an index into the array based on the current time.Type: GrantFiled: November 20, 2006Date of Patent: December 15, 2009Assignee: Juniper Networks, Inc.Inventors: Szelap Philip Chang, Manoj Apte, Saravanan Deenadayalan
