A method for providing location access management includes receiving a request for access data with respect to one or more regions based on location data associated with a movable object, determining that an access level associated with a restricted region of the one or more regions is restricted, displaying a message based on the access level associated with the restricted region on a user interface of a client device, receiving a request to unlock the restricted region, unlocking the restricted region, updating a data structure corresponding to a region identifier and representing the restricted region, to indicate that the restricted region is unlocked, and sending the updated data structure to update the access data for the movable object. The access data includes one or more data structures representing the one or more regions. The request includes the region identifier associated with the restricted region.

Techniques for location access management in a movable object environment

A system for collecting information regarding a flight restriction region includes one or more processors and a non-transitory computer readable storage medium storing instructions that, when executed by the one or more processors, cause the one or more processors to individually or collectively receive an input specifying a location of the flight restriction region from a user via a user input device, obtain information associated with the flight restriction region from one or more external data sources based on the location, and determine a space of the flight restriction region based on the information associated with the flight restriction region.

The present disclosure provides a thermal-stress-pore pressure coupled electromagnetic loading triaxial Hopkinson bar system and test method, the system mainly consists of an electromagnetic pulse generation system, a servo-controlled axial pressure loading system, a servo-controlled confining pressure loading system, a thermal control system, a pore pressure loading system, a bar system, and a data monitoring and acquisition system. Based on the conventional Hopkinson bar, the present disclosure creatively introduces a real-time loading and control system for confining pressure, thermal, and pore pressure, aiming to solve the technical problem that the existing test apparatus cannot be used to study dynamic response of deep rock mass under the coupling effect of thermal-stress-pore pressure and dynamic disturbance during dynamic impact loading.

A method for providing location access management includes requesting access data from an access manager based on location data associated with a movable object, receiving the access data determining accessibility of one or more regions to the movable object, and sending the access data to the movable object via a connection to the movable object.

A motor includes a stator, a rotor rotatable relative to the stator, a circuit board fixed to the stator, and a heat sink disposed on the circuit board, a side surface of the circuit board facing the heat sink has an insulating region and a metal heat dissipation region without solder mask. The thermal resistance between the circuit board and the heat sink can be reduced by the metal heat dissipation region, thereby improving the heat dissipation of the circuit board.

Motor

A motor includes a stator, a rotor rotatable relative to the stator, a support member, and a circuit assembly. The circuit assembly includes a plurality of electronic components. The rotor is rotatably mounted to the support member. The stator is received in the rotor. The stator is fixed to the support member, and the support member is at least partially received in an inner side of the stator. A portion of the support member received in the inner side of the stator defines a receiving space, and at least part of the electronic components of the circuit assembly is received in the receiving space of the support member. The support member is partially received in the inner side of the stator, and the circuit assembly is at least partially received in the support member, which makes the motor have a relatively smaller axial size.

A magnetic core for an electric motor has a ring-shaped yoke, teeth extending outwardly from the yoke, and a tooth tip extending from a distal end of each tooth. The core is formed from curved or coils strip laminations having teeth arranged in tooth groups. Each group has four tooth types arranged sequentially. Each tooth has left and right half tooth tips. The length of the half tooth tips vary according to tooth type. When assembled, first type tooth overlap with third type teeth and second type teeth overlap with fourth type teeth, whereby the opening of the winding slot is narrowed compared to laminations having all identical teeth.

Systems, devices, and methods are provided for managing flight restriction regions. The flight restriction regions of the present disclosure may comprise a plurality of distinct levels and may comprise releasable flight restriction regions. The releasable flight restriction regions may be released based on authentication of an operator of a UAV.

Systems and methods for managing flight-restriction regions

A system for collecting information regarding a flight restriction region includes one or more processors and a non-transitory computer readable storage medium storing instructions that, when executed by the one or more processors, cause the one or more processors to individually or collectively receive, from a user input device, an input designating one or more parameters of the flight restriction region. The one or more parameters include a location of the flight restriction region. The instructions further cause the one or more processors to determine a space for the flight restriction region based on the one or more parameters.

An ECU, a control box, and a CMF using the ECU are provided. The control box includes a heat sink and the ECU. The ECU include a support bracket mounted on the heat sink, a power supply board supported by the support bracket, and a signal board stacked over the power supply board and electrically connecting with the power supply board. The support bracket is made of an insulation material. The power supply board carries a plurality of power devices which are in contact with the heat sink for heat dissipation multiple power devices.

A permanent magnet motor has a number of permanent magnets forming permanent magnet poles. Each magnet has an outer surface that is an arc surface with a convex middle. An inner surface of the magnet is a curved surface with a concave middle. The curved surface has an arc surface section and two planar surface sections. The arc surface has a pole arc angle &#x3b1; of 0.7 to 0.96, and the ratio of an arc angle &#x3b2; of the arc surface section to the pole arc angle &#x3b1; is 0.15 to 0.35. The shape of the inner surface of the magnet creates uneven air gaps between the rotor poles and the stator core poles. This reduces cogging torque, increases the motor efficiency, and reduces the motor noise.
