Abstract: A method for detecting an object utilizing a monocular camera obtains an image showing an object and determining a pixel coordinate of the object in the image and determining a spatial position of the object in the image, based on the pixel coordinate of the object in the image and a preset coordinate transformation relationship or a preset depth prediction model. The image showing the object is obtained through the monocular camera, and the pixel coordinates of the object in the image are determined. According to the pixel coordinates of the object in the image and the preset coordinates transformation relationship or the preset depth prediction model, the spatial position of the object in the image is determined, providing efficient and accurate detection. An electronic device and a non-transitory storage recording the method are also disclosed.

Abstract: An ultrasonic ranging device includes an ultrasonic transmitter, an ultrasonic transmitting/receiving circuit, and a controller. The ultrasonic transmitter includes transmitting channels arranged in a ring. Each of the transmitting channels transmits a first ultrasonic wave. The first ultrasonic wave is reflected by a target object, the reflection of the first ultrasonic wave is defined as a second ultrasonic wave. Each of the transmitting channels receives the second ultrasonic wave. The ultrasonic transmitting/receiving channel controls the ultrasonic transmitter to transmit the first ultrasonic wave or receive the second ultrasonic wave by switching between working modes. The controller obtains a distance to the target object according to a transmitting time of the first ultrasonic wave and a receiving time of the second ultrasonic wave.

Abstract: A connector module and an electronic device using the same are provided. The connector module is disposed on a main body of an electronic device, and comprises a connector and a door structure. The connector has a slot used for accommodating the electronic card. The door structure comprises a door, a push rod and a connection rod. The door is used for covering the slot. The push rod is connected to the door and used for pressing the electronic card. The connection rod is disposed on the door and movably connected to the connector. When the door structure covers the slot, the push rod enters the slot and staggers with the electronic card.

Abstract: A display device includes a panel module, a frame, and a fixing device, wherein the panel module has a panel connecting part. The frame has a frame connecting part whose location corresponds to the location of the panel connecting part. The fixing device includes a joint unit and a fixing unit. The joint unit is used for accommodating the panel connecting part and the frame connecting part. The fixing unit is connected to the joint unit such that the frame can be fixed on the panel module.
