Publication number: 20210242897Abstract: A Radio Frequency (RF) circuit including a receive path, a transmit path, a switching circuit, and an output configured to receive RF signals from an antenna in a receive mode of operation, and to provide RF signals to the antenna in a transmit mode of operation. The receive path is configured to be coupled between a low-noise amplifier and the output. The switching circuit is located in the receive path and is configured, in the receive mode, to selectively couple the low-noise amplifier to the output and to pass the received RF signals from the output to the low-noise amplifier. The transmit path is configured to be coupled between a power amplifier and the output, to provide, in the transmit mode, signals from the power amplifier to the output, bypassing the switching circuit, and to have, in receive mode of operation, an off-state impedance of at least 200+j*13 Ohm.Type: ApplicationFiled: April 21, 2021Publication date: August 5, 2021Inventors: Foad Arfaei Malekzadeh, Sanjeev Jain, Stephen Joseph Kovacic

Patent number: 10918231Abstract: A temperature regulating beverage container lid is provided. The device has a lid with a top surface, at least one annular sidewall, and an internal wall defining a drinking chamber and a ventilation chamber. The perimeter of the sidewall of the lid can secure over the brim of a beverage container. The drinking chamber has a floor and a drinking spout, the drinking spout in fluid communication with a tubular member. The tubular member, in turn, is in fluid communication with an aperture in the floor. The tubular member is surrounded by a material with a high thermal capacity. An aperture in the top surface of the lid provides ventilation while the ventilation chamber is sized to receive the drinking spout of an identical temperature regulating beverage container lid.Type: GrantFiled: May 20, 2020Date of Patent: February 16, 2021Inventor: Sanjeev Jain

Publication number: 20200356492Abstract: Multiprocessor clusters in a virtualized environment conventionally fail to provide memory access security, which is frequently a requirement for efficient utilization in multi-client settings. Without adequate access security, a malicious process may access what might be confidential data that belongs to a different client sharing the multiprocessor cluster. Furthermore, an inadvertent programming error in the code for one client process may accidentally corrupt data that belongs to the different client. Neither scenario is acceptable. Embodiments of the present disclosure provide access security by enabling each processing node within a multiprocessor cluster to virtualize and manage local memory access and only process access requests possessing proper access credentials. In this way, different applications executing on a multiprocessor cluster may be isolated from each other while advantageously sharing the hardware resources of the multiprocessor cluster.Type: ApplicationFiled: July 23, 2020Publication date: November 12, 2020Inventors: Samuel Hammond Duncan, Sanjeev Jain, Mark Douglas Hummel, Vyas Venkataraman, Olivier Giroux, Larry Robert Dennison, Alexander Toichi Ishii, Hemayet Hossain, Nir Haim Arad

Patent number: 10789637Abstract: A server system increases the diversity of item recommendations provided to a target user by using item similarity data to reorder a ranked list of recommended items for presentation to a user. The reordering is performed such that items identified as similar to each other are spaced apart from each other by at least a minimum number of positions. This minimum number may be selected based, e.g., on how many recommended items will initially be presented on a requesting user device, which may depend on the display size or other attributes of the user device. The server system generates a user interface that displays an initial portion of the reordered list. The user interface includes controls for scrolling through the reordered list.Type: GrantFiled: September 17, 2018Date of Patent: September 29, 2020Assignee: Amazon Technologies, Inc.Inventors: Sanjeev Jain, Brent Russell Smith, Alexandra Juliet Brasch
