Publication number: 20240086959Abstract: A content sharing management system and an associated method for allowing a subscriber of a media platform to share media content available on the media platform as a gift or as a recommendation to a non-subscriber of the media platform is provided. The content sharing management system allows the non-subscriber to pay and consume only a recommended media content rather than needing to pay a hefty yearly subscription fee, thus enabling significant cost savings. The content sharing management system increases a subscription revenue of the media platform, and provides the subscriber with incentives for sharing media content to the non-subscriber. The content sharing management system further ensures that only the non-subscriber who purchased a particular media content or to whom the media content is gifted can access the media content via an associated secured access link, and prevents other non-subscribers from accessing the media content via the secured access link.Type: ApplicationFiled: September 8, 2023Publication date: March 14, 2024Applicant: TATA ELXSI LIMITEDInventors: CHANDRASEKHAR VISHWARAJU, ADITYA SATHYANARAYANA MANJUNATHA

Publication number: 20240063732Abstract: A motor controller (100) is provided for smooth operation of an electric motor (102), which mitigates torque ripple, noise and vibration effects, and increases a life span of the motor (102). The motor controller (100) includes a speed controller (120), current transformation units (128 and 130), a current controller (132), and a pulse width modulation (PWM) signal generator (134). The current controller (132) determines a duty cycle of PWM gate signals used for controlling a rotor (104) speed within a particular sector (302A) of the motor (102) based on a reference quadrature-axis current and an actual quadrature-axis current. The PWM signal generator generates the PWM gate signals having the determined duty cycle, controls the rotor (104) speed, and incrementally varies a current speed of the motor (102) to achieve a target speed by modulating operations of a specific pair of inverter switches (502C and 502E) using the PWM gate signals.Type: ApplicationFiled: December 16, 2021Publication date: February 22, 2024Applicant: TATA ELXSI LIMITEDInventors: Anush Gopalakrishnan NAIR, Krishna Priya GANESH, Reshma RAVI

Publication number: 20240059277Abstract: A method for automatic navigation and parking of a vehicle (202) in a tight parking space using a navigation system (200) is provided. The method includes identifying a vacant slot (406C) in a designated area (204) and stopping the vehicle (202) at a current position (412) within the designated area (204) upon identifying the vacant slot (406C). The method further includes determining a linear distance by which the vehicle (202) has to initially move from the current position (412) to a start point (426) for ultimately reaching a destination point (418) within the vacant slot (406C) via a middle point (438) and a tangential point (422). The navigation system (200) determines the linear distance based on a horizontal distance between the tangential point (422) and a collinear point (436) and one or more coordinates of the tangential point (422), the start point (426), and the current position (412).Type: ApplicationFiled: December 16, 2021Publication date: February 22, 2024Applicant: TATA ELXSI LIMITEDInventors: Mansi Shrirang Patil, Jyotsana Singh

Patent number: 11426526Abstract: A dispensing device is provided to dispense a designated amount of a material on every dose delivery operation. The dispensing device includes a thumb pad, a cam drum coupled to the thumb pad, and a pawl nut comprising a one-way pawl. The thumb pad may be pulled out in a direction away from a distal end of the dispensing device for setting a dose of the material to be dispensed out and may be pushed in towards the distal end for delivering the dose. The cam drum includes a plurality of linear cam profiles and a plurality of helical cam profiles that may be disposed on a surface of the cam drum. The one-way pawl may engage with a ratchet disposed at a distal end of the cam drum and may prevent a rotation of the cam drum in an undesired direction.Type: GrantFiled: February 5, 2018Date of Patent: August 30, 2022Assignee: Tata Elxsi LimitedInventors: Vasanthan Mani, Suresh Kumar Natarajan

Publication number: 20190374725Abstract: A dispensing device (102) is provided to dispense a designated amount of material on every dose delivery operation. The dispensing device (102) includes a thumb pad (202) and a cam drum (204) that is coupled to the thumb pad (202). The thumb pad (202) is configured to be pulled out towards a proximal end (104) of the dispensing device (102) for setting a dose of a material to be dispensed out and to be pushed in towards a distal end (106) of the dispensing device (102) for delivering the dose. The cam drum (204) includes at least one linear cam profile (402) and at least one helical cam profile (404) that are disposed on a surface of the cam drum (204). The thumb pad (202) is configured to ride on the linear cam profile (402) when setting the dose and on the helical cam profile (404) when delivering the dose.Type: ApplicationFiled: February 5, 2018Publication date: December 12, 2019Applicant: Tata Elxsi LimitedInventors: Vasanthan MANI, Suresh Kumar NATARAJAN

Patent number: 10303817Abstract: An emulator for a test scenario corresponding to a connected vehicle application is presented. The emulator includes a test bed for testing a device under test (DUT) communicatively coupled to emulated intelligent transportation system (ITS) stations. The test bed also includes a processor configured to emulate the test scenario based on user-defined configuration parameters that define a behavior of the DUT and each of the emulated ITS stations during simulated events in the test scenario. The processor further includes a mobility engine configured to generate and periodically update one or more mobility parameters corresponding to the DUT and the emulated ITS stations based on the corresponding configuration parameters. The test bed further includes a channel emulator, a controller area network (CAN) simulator, and a global navigational satellite system (GNSS) simulator integrated into a single test bed for holistically emulating the test scenario and validating a desired functionality of the DUT.Type: GrantFiled: July 21, 2016Date of Patent: May 28, 2019Assignee: Tata Elxsi LimitedInventors: Gnanaprakash Sebastian, Karthikeyan Padmanaban, Biswajit Biswas, Rajagopalan Rajappa
