Patent number: 11356837Abstract: A method performed by a station that includes receiving information from a cell of a Public Land Mobile Network (PLMN), determining whether the information indicates the cell supports circuit switched fallback (CSFB) voice calls, when the CSFB voice calls are not supported, determining whether at least one packet switched voice property of the station satisfies a predetermined condition and attaching to the cell of the PLMN when the predetermined condition is satisfied. A further method performed by a station connected to a PLMN that includes identifying cells of the PLMN available for the station to camp on, determining whether the station is capable of executing packet switched calls, when the station is not capable of executing packet switched calls, determining whether the identified cells have a neighbor cell that supports CSFB voice calls and prioritizing the cells that are identified as having neighbor cells that support CSFB voice calls.Type: GrantFiled: May 11, 2017Date of Patent: June 7, 2022Assignee: Apple Inc.Inventors: Gahima S.

Patent number: 10547558Abstract: Methods, systems and apparatus for a user equipment to implement a dynamic discard timer. The user equipment may generate a packet for transmission and store the packet in a buffer of the user equipment. The user equipment may then generate a timeout value for a discard timer for the buffer, where the discard timer discards the packet from the buffer when the timeout value is reached. After a predetermined amount of time, the user equipment may determine whether the packet has been discarded from the buffer and, when it is determined that the packet has not been discarded from the buffer, update the timeout value.Type: GrantFiled: May 31, 2017Date of Patent: January 28, 2020Assignee: Apple Inc.Inventors: An Chan, Soo Young Lee, Abhishek A.

Patent number: 9735549Abstract: Photonic integrated circuits (PICs) are based on quantum cascade (QC) structures. In embodiment methods and corresponding devices, a QC layer in a wave confinement region of an integrated multi-layer semiconductor structure capable of producing optical gain is depleted of free charge carriers to create a low-loss optical wave confinement region in a portion of the structure. Ion implantation may be used to create energetically deep trap levels to trap free charge carriers. Other embodiments include modifying a region of a passive, depleted QC structure to produce an active region capable of optical gain. Gain or loss may also be modified by partially depleting or enhancing free charge carrier density. QC lasers and amplifiers may be integrated monolithically with each other or with passive waveguides and other passive devices in a self-aligned manner. Embodiments overcome challenges of high cost, complex fabrication, and coupling loss involved with material re-growth methods.Type: GrantFiled: July 27, 2016Date of Patent: August 15, 2017Assignees: Massachusetts Institute of Technology, Pendar Technologies, LLCInventors: Anish K.

Patent number: 8406267Abstract: A solid-state gain element including a thin doped region in which an optical signal propagates through the thin doped region at a large angle with respect to the normal to the thin doped region, reflects at a boundary of the thin doped region, and passes through the thin doped region again. An optical pump beam propagates through the thin doped region also at a large angle with respect to the normal to the thin doped region. In one example, the gain element and source of the pump beam are configured such that there is total internal reflection of the pump beam at the boundary of the thin doped region for a second pumping pass through the thin doped region. In another example, an elliptically symmetric laser beam is used to create a circularly symmetric gain region in the thin doped region.Type: GrantFiled: February 20, 2009Date of Patent: March 26, 2013Assignee: Massachusetts Institute of TechnologyInventors: Daniel J Ripin, Tso Yee Fan, Anish K Goyal, John Hybl
