The method includes: pre-processing vertebra CT image data; inputting the pre-processed vertebra CT image data into a pre-trained neural network to obtain regression results of heat maps of key points corresponding to the pre-processed vertebra CT image data; regressing of 3D heat maps corresponding to the positions of the key points of the vertebra mass center based on the regression results of the heat maps of the key points and the pre-processed vertebra CT image data; serving 3D heat maps corresponding to the positions of the key points of the vertebra mass center as labels, and networked regressing 3D heat map information to position the vertebra. Effects caused by scanning machine difference and scanning noise are avoided, and the vertebra with complex forms is accurately positioned.

In an example, a system may adapted so that, while a first device of a first type and a second device of the first type are simultaneously connected to a client device, the first device, rather than the second device, is used as an active device of the first type for at least one application, the first and second devices being peripheral devices. The system may be further adapted so that, while both the first and second devices remain connected to the client device, a switch from the first device to the second device by a user is determined, and, based on the switch from the first device to the second device, the second device, rather than the first device, is used as the active device of the first type for the at least one application.

Abstract: Systems and methods are disclosed for providing sensor data to a host processor. A sequence of data samples may be generated at a sample rate established by a clock source associated with the sensor. A time stamp derived from another clock source, such as the clock employed by the host processor, is assigned to at least one of each periodically retrieved data samples. As such, at least one of the assigned time stamps then may be adjusted by applying a correction determined from a timing characteristic associated with retrieval of the data samples.
