摘要:
This application discloses a background subtraction-mediated data dependent acquisition method useful in mass spectrometry analysis. The method includes subtraction of background data from precursor ion spectra of a sample in real-time to obtain mass data of component(s) of interest and performs data-dependent acquisition on the component(s) of interest based on the resultant mass data from the background subtraction step. The present invention also encompasses mass spectrometer systems capable of background subtraction-mediated data-dependent acquisition and computer programs adapted for use in the background-subtraction-mediated data-dependent acquisition. The invention thus provides highly sensitive data-dependent acquisition for minor components of interest in a sample.

The present invention provides a system for developing sense of rhythm. The system includes an interactive surface embedded with an RF antenna, a host, a memory unit, and a media player, an array of contact points on the interactive surface, a display device configured to export the comparison of the tempo and the beat input by a player with the preset tempo and the preset beat, and multiple physical sheets. The function of each contact point is determined or changed by the host in accordance with preset programs. Each physical sheet is embedded with an RFID tag and marked with a musical instrument and corresponding functional components, and the location of the functional components corresponds to the contact points in accordance with the preset programs. Once a physical sheet is placed on the interactive surface, the host is configured to assign a timbre of a musical instrument and the corresponding playing rules to the array of contact points in accordance with the preset programs and the RFID tag embedded in the physical sheet. The visible feedback would help players make corrections more efficiently.
摘要:
A method and an apparatus for detecting an abnormal situation are disclosed. The method includes recognizing whether a detection target exists in a captured image; generating, based on the captured image, a three-dimensional point cloud of the detection target in the captured image, when the detection target exists; obtaining, based on the generated three-dimensional point cloud, one or more current posture features of the detection target; and determining, based on the current posture features and one or more predetermined posture feature standards, whether the abnormal situation exists, the posture feature standards being previously determined based on one or more common features when the detection target performs a plurality of abnormal actions.
摘要:
A communication system, a user equipment and a base station are disclosed. The communication system includes a user equipment and a base station, wherein the user equipment is configured in a first communication system and having a co-existence working mode in which the user equipment performs a first communication with a base station in the first communication system and performs a second communication with an apparatus of a second communication system, which is different from the first communication system in a time-division multiplexing manner or a frequency-division multiplexing manner.
摘要:
Method, device, and non-transitory computer-readable medium detecting a gathering of objects based on stereo vision are disclosed, and the method comprises steps of obtaining current and prior images and a corresponding depth map; extracting foreground pixels corresponding to detection objects from the current and prior images, and projecting the foreground pixels onto a ground surface to acquire a foreground projection image including foreground projection blocks; conducting, based on image feature differences of the foreground pixels between the current and prior images, projection onto the ground surface to acquire moving foreground projection blocks; utilizing the moving foreground projection blocks to erode the foreground projection blocks to obtain still foreground projection blocks; and determining, based on the still foreground projection blocks, whether the gathering of objects exists.
摘要:
A method of manufacturing a semiconductor device is disclosed. A p-type substrate is doped to form an N-well in a selected portion of a p-type substrate adjacent an anode region of the substrate. A p-type doped region is formed in the anode region of the p-type substrate. The p-type doped region and the N-well form a p-n junction.
