Publication number: 20230350987Abstract: Users and providers register with a portal. Users are provided codes that link to the portal and contact information for the users. When a provider needs a user to physically sign a document, the user presents the code for scanning by a provider device, this redirects the document and the code to the portal. A ledger is maintained on the portal for the transaction, the portal forwards the document to the user using the contact information. The user uses an application to review the document and accept or reject the document. When the user accepts the document, a physical signature of the user is placed within the document at signature locations and forwarded back to the portal. The portal updates the ledger indicating the user physically signed and forwards the physically signed document to the provider. Neither the unsigned document nor the physically signed document are stored on the portal.Type: ApplicationFiled: April 30, 2022Publication date: November 2, 2023Inventor: Arun George Eapen

Patent number: 11700581Abstract: Methods and apparatus are disclosed for uplink power control of a terminal in a satellite communication system. Calibration data that includes output backoff values corresponding to input backoff values for each of a first set of calibration frequencies is initially stored in the terminal. A normalized transmit power for the terminal is determined for multiple transmit frequencies based on the calibration data. Upon receiving an assigned frequency for communicating, the terminal selects one of the normalized transmit power previously determined and begins transmitting.Type: GrantFiled: June 24, 2019Date of Patent: July 11, 2023Assignee: Hughes Network Systems, LLCInventors: Murali Regunathan, George Eapen

Patent number: 10079637Abstract: A very small aperture terminal (VSAT) installation tool is provided having the ability to measure cable loss along an interfacility link (IFL) between an outdoor unit and an indoor unit of the VSAT. Radio frequency (RF) signals can be transmitted from the indoor unit to the outdoor unit, where the RF signals are intercepted along the IFL prior to reaching the outdoor unit, and the output power is determined. The determined output power is compared to an expected output power at the indoor unit. The delta between the determined output power and the expected output power can be used to adjust the power of the indoor unit such that the outdoor unit can operate without reaching its compression point.Type: GrantFiled: July 18, 2016Date of Patent: September 18, 2018Assignee: Hughes Network Systems, LLCInventors: Emanuel Girard Harrington, George Eapen, Yong Kang Yuan

Patent number: 9515860Abstract: Systems and methods provide a receiver design capable of both wideband (high symbol rate) and narrowband (low symbol rate) operations requirements without compromising narrowband performance. Moreover, such a receiver design can be very low cost, and eschewing the need for any expensive and/or specialized elements. A receiver configured in accordance with various embodiments utilizes a fully integrated tuner in which narrowband filters are configured to be bypassable when in wideband (high symbol rate) mode in favor of fixed wideband filters. Additionally, an analog-to-digital converter (ADC) can be implemented with digital gain for wideband operation, as well as digital data bit mapping to accommodate industry standard application-specific integrated circuits (ASICs) interfaces, such as from a 12 bit ADC core to an 8 bit digital interface.Type: GrantFiled: December 30, 2014Date of Patent: December 6, 2016Assignee: Hughes Network Systems, LLCInventors: George Eapen, Yong Kang Yuan, Emanuel Harrington

Patent number: 9473193Abstract: A mobile terminal for satellite communications receives communication, e.g., from a gateway via a satellite link. A frequency lock loop unit locks to the carrier frequency of the received communication. The mobile terminal includes a global positioning system for receiving global positioning data. The mobile terminal determines the Doppler frequency shift of the received communications based on the global positioning data. The mobile terminal generates a reference clock for return transmissions based on the frequency of the frequency lock loop, corrected for the Doppler shift. A correction factor of two times the determined Doppler frequency shift is used, to compensate for both a forward and return transmission link.Type: GrantFiled: December 29, 2014Date of Patent: October 18, 2016Assignee: Hughes Network Systems, LLCInventors: Jack Lundstedt, John Schmid, Guy Montgomery, Bahman Salamat, George Eapen, Yeqing Tang, Brian Smith
