  • Publication number: 20250258304
    Abstract: In estimating a position of a vehicle utilizing a global navigation satellite system (GNSS), it is desirable to exclude outliner GNSS measurements due to navigation signals via non-light-of-sight paths from the GNSS to the vehicle, but it leads to a distorted satellite geometry distribution. Complementariness between low-lying visual landmarks and healthy but high-elevation satellite measurements is explored to improve the geometry constraint. Measurements of an inertial measurement unit, low-lying visual landmarks captured by a forward-looking camera onboard the vehicle, and healthy but high-elevation satellite measurements are tightly-coupled integrated via sliding window optimization of system states used in a factor graph. To improve estimation performance, good initial guesses of system states are important.

  • Patent number: 12292340
    Abstract: In an indoor environment on fire, automatic deployment of sensors disposed on, beneath or over the floor to look upward the ceiling to observe a body of smoke and flame risen near the ceiling allows important information regarding states and dynamics of the body of smoke and flame to be gathered at an early stage of fire (e.g. before arrival of firefighters). By distributing the sensors over the indoor environment, the states and dynamics of the body of smoke and flame are monitored holistically (i.e. as a whole) even at the early stage of fire. Such information is useful to predict development of the fire. In one implementation, a sensor is held in an infrastructure sensor holder mounted on the ceiling during normal time. Upon detecting occurrence of fire, the sensor drops from the holder to land on the floor and orients a sensing direction vertically upward to perform monitoring.

  • Publication number: 20250138050
    Abstract: A vertical probe includes opposite first and third sides, and opposite second and fourth sides. The third and fourth sides extend in a planar manner from a body to a tip portion. The first and second sides include first and second upper plane segments at the body, first and second transition segments at the tip portion, and first and second lower plane segments closer to the third and fourth sides than the first and second upper plane segments are, respectively. The first and second transition segments gradually approach the third and fourth sides as they extend from the first and second upper plane segments to the first and second lower plane segments. The first transition and lower plane segments are realized by laser processing. The vertical probe can contact small conductive contacts with good current resistance, structural strength, lifespan, and processing accuracy. When applied to a probe head, breaking or shifting position of the tip portion due to vertical movement can be avoided.

  • Patent number: 12123961
    Abstract: A method for supporting positioning of a vehicle using a satellite positioning system is disclosed. The method includes generating, in real-time, a sliding window map (SWM) based on 3D point clouds from a 3D LiDAR sensor and an attitude and heading reference system (AHRS), wherein the SWM provides an environment description for detecting and correcting a non-line-of-sight (NLOS) reception; accumulating the 3D point clouds from previous frames into the SWM for enhancing a field of view (FOV) of the 3D LiDAR sensor; receiving global navigation satellite system (GNSS) measurements from satellites, by a GNSS receiver; detecting NLOS reception from the GNSS measurements using the SWM; correcting the NLOS reception by NLOS remodeling when a reflection point is not found in the SWM; and estimating a GNSS positioning by a least-squares algorithm. It is the objective to provide a method that mitigates NLOS caused by both static buildings and dynamic objects.

  • Patent number: 11664734
    Abstract: A flyback converter to control conduction time in AC/DC conversion technology. The flyback converter includes a primary side and a secondary side. The primary side includes a main switch connecting a primary coil to the input of the flyback converter in series. The secondary side includes a secondary coil coupling with the output terminal of the flyback converter. When a switching frequency of the main switch is at a preset first on time in the range between the off frequency and the second switching frequency, the on-time of the main switch continuously changes corresponding to output load changes. When the switching frequency of the main switch is higher than the first switching frequency, the on time of the main switch is constant. The on time is controlled to change linearly, so as to avoid excessive changes in the output voltage ripples, thereby improving circuit efficiency.

  • Publication number: 20230069336
    Abstract: A method of optimizing the scheduling of storage resource for a server used in cloud computing obtains a first input/output operations per seconds (IOPS) value of a virtual disk in an instance. A warning message is generated when the first IOPS value is larger than a predefined threshold value, which represents an overloaded state of the virtual disk. An predicted IOPS value is obtained and the predicted IOPS value is set as the maximum IOPS value for limiting the IOPS value of the virtual disk, thus other virtual disks are not affected by a virtual disk being overloaded, and storing efficiency of the server is improved. A server and a computer readable storage medium applying the method are also disclosed.

  • Patent number: 11387738
    Abstract: When a constant on-time flyback converter is in the switch-on stage, the gate voltage of the switch and the input voltage of the flyback converter adopt the primary side of the transformer to control. The gate voltage is controlled by the second control signal generated by the controller. The flyback converter is then turn off to enter the switch off stage. When the flyback converter is in the switch off stage, the secondary side controller on the secondary side of the transformer, based on the output voltage and output current of the secondary side, sends a first control signal to the primary side controller to control the main switch to turn on. Thus, the flyback converter enters the switch-on stage. Therefore, the calculation complexity is reduced, and there is no need to set a blanking time, such that the flyback converter can be used in high switching frequency applications.
