Publication number: 20220304049Abstract: A method, apparatus and system for medium access control is provided. Time slots configured to include mini slots at the beginnings thereof. Devices are assigned time slot, mini slot combinations as transmission opportunities. A device can attempt to use a transmission opportunity when it has a packet to send, by beginning data transmission in its assigned slot and mini slot and potentially continuing the transmission up until the end of the assigned slot. If another device is already transmitting in the assigned slot, the device refrains from using its transmission opportunity. Higher priority devices can be assigned transmission opportunities corresponding to earlier mini slots within a slot. In some embodiments, multiple devices can be assigned the same transmission opportunity and a collision detection mechanism can be employed. In some embodiments, all devices detect if a slot is idle and advance the beginning of the next slot upon such detection.Type: ApplicationFiled: June 10, 2022Publication date: September 22, 2022Applicant: Huawei Technologies Canada Co., Ltd.Inventors: Weihua ZHUANG, Jie GAO, Xuemin SHEN, Xu LI

Patent number: 11333682Abstract: A probe includes a first rod having a first axis and a second rod having a second axis. A first end of the first rod is connected to a first end of the second rod to form an angle that maintains a “total internal reflection” effect for waves propagating through the probe. A second end of the second rod includes a prong facilitating attachment of the probe to a housing block. The first axis and the second axis define a plane. A second end of the first rod includes a tapered face formed perpendicular to the plane. The tapered face is sufficiently flat to make planar contact with a portion of a component under study. A support is formed in the plane and connected to the second rod. A second end of the support includes a connector to facilitate attachment of the probe to the housing block.Type: GrantFiled: March 13, 2020Date of Patent: May 17, 2022Assignee: HUAWEI TECHNOLOGIES CANADA CO., LTD.Inventors: Haotian Zhu, Ke Wu, Jules Gauthier

Publication number: 20220098209Abstract: The present invention relates to highly polarizable 3D organic perovskites of the general formula ABX3, prepared by introducing halogen functional groups in the A-site cation (in which the A and B sites are occupied by organic cations and the X site is a monovalent non-metallic counterion). The (DCl)(NH4)(BF4)3 crystal exhibits a strong linear electrooptic (EO) effect with an effective EO coefficient of 20 pmV?1, which is 10 times higher than that of metal halide perovskites. These 3D organic perovskites are solution processed and compatible with silicon, and illustrate the potential of rationally-designed all-organic perovskites for use in on-chip modulators, electro-optic devices, piezoelectric devices, or silicon photonics devices.Type: ApplicationFiled: September 1, 2021Publication date: March 31, 2022Applicant: Huawei Technologies Canada Co., Ltd.Inventors: Meng-Jia SUN, Chao ZHENG, Sjoerd HOOGLAND, Edward Hartley SARGENT

Publication number: 20210408399Abstract: A class of crystals comprises an inorganic lattice in which organic molecules are embedded, thereby allowing macroscopic electro-optic responsiveness. The lattice is based on a metal halide perovskite structure. The organic molecules can be with an intrinsic dipole such that when aligned and fixed in place in the inorganic lattice, they induce electro-optic responsiveness in the macroscopic crystal. Alternatively, their mere presence in the structure can induce sufficient polarity in the scaffold itself for a similar responsiveness. The molecules themselves can comprise a carbon backbone that is completely conductive, partially conductive, or non-conductive, as well as zero, one or two functional groups that allow binding to the lattice and increased polarity.Type: ApplicationFiled: October 9, 2020Publication date: December 30, 2021Applicant: Huawei Technologies Canada Co., Ltd.Inventors: Sjoerd HOOGLAND, Grant William WALTERS, Yuan GAO, Edward Hartley SARGENT
