  • Patent number: 11467031
    Abstract: A method is presented for determining path length fluctuations in an interferometer using a reference laser with an arbitrary frequency with respect to the measured light. The method includes: injecting reference light along signal paths of the interferometer; measuring interference between the reference light at an output of the interferometer; determining an optical phase difference between the reference light in the two signal paths of the interferometer by measuring intensity modulation of the interference between the reference light and subtracting an intended frequency modulation from the measured intensity modulation; accumulating an unwrapped phase difference between the reference light in the two signal paths of the interferometer, where the unwrapped phase difference is defined in relation to a reference; and determining path length fluctuation of light in the interferometer using the unwrapped phase difference.

  • Publication number: 20220322235
    Abstract: A low-power standard-compliant NB-IoT wake-up receiver (WRX) is presented. The WRX is designed as a companion radio to a full NB-IoT receiver, only operating during discontinuous RX modes (DRX and eDRX), which allows the full high-power radio to turn off while the wake-up receiver efficiently receives NB-IoTWake-Up Signals (WUS). The fabricated receiver achieves 2.1 mW power at ?109 dBm sensitivity with 180 kHz bandwidth over the 750-960 MHz bands. The WRX is fabricated in 28 nm CMOS and consumes 5× less power than the best previously published traditional NB-IoT receivers. This disclosure is the first designed dedicated wake-up receiver for the NB-IoT protocol and demonstrates the benefits of utilizing a WRX to reduce power consumption of NB-IoT radios.

  • Publication number: 20220303305
    Abstract: One commonality among most vehicular security attacks reported to date is that they ultimately require write access to the CAN bus. In order to cause targeted and intentional changes in the vehicle behavior, malicious CAN injection attacks require knowledge of the CAN message format. However, since this format is proprietary to OEMs and can differ even among different models of a single make of vehicle, one must manually reverse-engineer the CAN message format of each vehicle they target. To mitigate this difficulty, an automated CAN message translator is presented.

  • Publication number: 20220281034
    Abstract: Due to geometric discontinuities introduced by welding and joining processes, stresses or strain cannot be calculated reliably calculated using modern analytical and computer methods as result of stress or strain singularity at joint locations, which leads to severe mesh sensitivity. Design and fatigue evaluation of these structures remain empirical. This disclosure addresses mesh insensitivity of stress/strain calculations for welded structures through a cut-plane traction stress method through a novel post processing of conventional finite element computation results, as well as provides a unified fatigue evaluation procedure for fatigue design and structural life evaluation for both low-cycle and high cycle fatigue regime subjected to either proportional or non-proportional multiaxial fatigue loading, as well as a simple and reliable method for treating spot welds.

  • Publication number: 20220281531
    Abstract: A composite part is manufactured by an additive process, which includes locating a layer of fibers, selectively depositing a matrix material in a predetermined pattern onto portions of the layer of fibers to form a matrix material layer, repeating these steps to generate a preform of the composite part, and applying heat and pressure to the preform to consolidate the layers of fiber and the layers of matrix material. During the depositing of the matrix material, voids are created within at least one layer of the matrix material by intentionally not depositing matrix material over predetermined areas of the layer of fibers, the predetermined areas configured to be within an outer boundary of the predetermined pattern of the matrix material.

  • Patent number: 11437829
    Abstract: Lithium-ion cells are widely used in various platforms, such as electric vehicles (EVs) and mobile devices. Complete and fast charging of cells has always been the goal for sustainable system operation. However, fast charging is not always the best solution, especially in view of a new finding that cells need to rest/relax after being charged with high current to avoid accelerated capacity fading. A user aware charging algorithm is proposed which maximizes the charged capacity within a user-specified available charging time (i.e., user-awareness) while ensuring enough relaxation (i.e., cell-awareness) and keeping cell temperature below a safe level.

First, a cementitious composite material comprising binder and water is conditioned, for example, in a mold by exposing the cementitious composite material to ?about 50% to ?about 80% relative humidity for ?about 3 hours to ?about 24 hours. The cementitious composite material is then dried to remove ?about 10% by weight of initial water in the cementitious composite material. The cementitious structure formed is capable of a carbon dioxide uptake level of greater than or equal to about 6% by weight binder. The cementitious structure has a tensile strain capacity of ?about 1% and a uniaxial tensile strength of ?about 1 MPa. The method may also include carbonating the cementitious structure, following by an optional further hydration process.
