A fingerprint recognition method and terminal device provide authentication by simultaneously collecting fingerprint data when a power-on signal is detected, attempting to match the fingerprint data with preset fingerprint data, and logging in to the terminal device proceeds when the matching succeeds.

Login method based on fingerprint recognition and device

A fingerprint recognition device having a login circuit is provided in a terminal apparatus. A power button is configured to interwork with a contact, wherein a contact closing stroke of the power button is less than a maximum stroke of the power button. A fingerprint collection circuit is disposed on the power button and a power control circuit is coupled to the power button and configured to control power output to supply power to the fingerprint collection circuit when detecting that the power button is pressed. The power control circuit also controls power output to supply power to the fingerprint collection circuit when detecting that the contact is closed. The fingerprint collection circuit is configured to collect fingerprint data and send the fingerprint data to a fingerprint recognition circuit configured to receive the fingerprint data from the fingerprint collection circuit and match the fingerprint data with preset fingerprint data. The login circuit is configured to log in to the terminal device when the fingerprint data match with the preset fingerprint data.

The present invention relates to phenyl [a]indole[2,3-g]quinolizine compounds represented by formula (I), a preparation method therefor, a pharmaceutical composition, and applications thereof. Specific applications are applications in the preparation of drugs for treating diseases related to a proprotein convertase subtilisin Kexin-9 (PCSK9), comprising the applications in the preparation of drugs for treating hyperlipemia, hypercholesterolemia, hypertriglyceridemia, fatty liver deformation, atherosclerosis, obesity and other metabolic diseases. 

Phenyl [a]indole[2,3-g]quinolizine compounds, preparation method therefor, pharmaceutical composition, and applications thereof

The application provides a radio frequency circuit, including: a first circuit and a second circuit. The first circuit is configured to receive a first signal and a second signal; split the first signal into a third signal and a fourth signal, and split the second signal into a fifth signal and a sixth signal; adjust a phase of the fifth signal to obtain a seventh signal; and combine the seventh signal and the third signal into an eighth signal. The second circuit includes a primary power amplifier branch and a secondary power amplifier branch, and the primary power amplifier branch is configured to process the fourth signal and the sixth signal, and the secondary power amplifier branch is configured to process the eighth signal.
