Provided are a method, apparatus, and computer-readable recording medium for authenticating a user. The user authentication method includes obtaining an image including a face and a face movement by driving a camera to extract feature information on a facial image and a movement pattern from the obtained image, and comparing the extracted feature information on the facial image with feature information on a facial image registered in a storage and, when the extracted feature information matches the registered feature information, comparing the extracted movement pattern with a movement pattern registered in the storage and, when the extracted movement pattern matches the registered movement pattern, unlocking a device.

A surgical instrument including a firing drive configured to advance a cutting member and/or staple driver within an end effector, and a brake configured to prevent, or at least partially inhibit, the relative movement of the cutting member and/or staple driver. The surgical instrument can further include a firing member operably engaged with the cutting member, for example, a band connected to the firing member, and a reel, where the band can be configured to be wound around the reel. In various embodiments, the brake can be selectively engageable with the reel and/or band to prevent, or limit, the movement of the band. The brake can include a brake surface where relative movement between the band and the brake surface can generate a friction force therebetween which can hold the firing member in position until a sufficient force is applied to the firing member to overcome the friction force.

A surgical instrument including a shaft assembly and an end effector, where the end effector can be moved relative to the shaft assembly. The shaft assembly can include a lock member selectively engageable with the end effector to limit, or prevent, relative movement therebetween. In at least one embodiment, the end effector can include a lock member having a plurality of teeth and/or a plurality of recesses, where the shaft assembly lock member can engage the teeth and/or recesses to fix the relative position between the end effector and shaft assembly. In various embodiments, the teeth can be positioned between first and second surfaces of the end effector lock member to reduce the possibility that the teeth can impinge on soft tissue surrounding the lock member. In other embodiments, the teeth can be beveled in order to allow the teeth to slide relative to the soft tissue.

The method has the effects that the password is high in complexity and high in dynamic property, and the condition that technical unlocking is performed by utilizing electromagnetic wave copy can be effectively avoided.

The invention discloses a touch screen unlocking method and electronic equipment with a touch screen. The method comprises the following steps: a signal receiving step: receiving touch signals on the touch screen through the electronic equipment at a screen locking state; a time starting step: judging whether position coordinates of the touch signals are positioned within a specific zone preset on the touch screen, and starting timing if the position coordinates of the touch signals are positioned within the zone, and an unlocking judgment step: judging whether the subsequent touch signals meeting unlocking conditions are received at least once within a timing period after timing is started, and triggering a touch screen unlocking program if the subsequent touch signals meeting unlocking conditions are received at least once within the timing period. The method and the electronic equipment reduce the probability of unlocking the touch screen caused by spurious triggering, and prevent the touch screen from being unlocked in unnecessary conditions, thereby improving the satisfaction degree of users.

A device for variably adjusting the control times of gas exchange valves of an internal combustion engine. The device has a driving element, an output element, at least one pressure chamber, at least one mechanism limiting the angle of rotation, and a pressure accumulator. A phase angle between the output and driving element is changed by delivering or discharging pressure medium to or from the pressure chambers. The mechanism limiting the angle of rotation has a receiving member and an engaging element to which a force is applied towards the receiving member (45). When locked, where the engaging element engages into the receiving member, the mechanism limiting the angle of rotation limits the phase angle of the output element relative to the driving element at least to an angular spread. The mechanism limiting the angle of rotation can be unlocked by applying pressure medium to the receiving member.

The screen unlock based identity identification method comprises (1) obtaining a touch end point of sliding operation on a screen; (2) judging whether the touch end point is matched with a beforehand user-defined target touch area or not; (3) executing unlocking operation and entering an owner access mode if yes and executing unlocking operation and entering a visitor access mode if not. The terminal equipment adopts the above the method. Under a to-be-unlocked state, a screen display image is a current wallpaper and the beforehand user-defined target touch area is an area which is performed on beforehand user-definition based on the current wallpaper. According to the screen unlock based identity identification method, the user owner or visitor identity can be identified through the common and no different sliding unlocking action, different modes of the equipment can be entered, and the purpose of protecting privacy is effectively achieved.

A smart entry system for a vehicle includes a transmitter on a vehicle and a portable unit carried by a user. The transmitter transmits a request signal which defines a user detection area to detect whether the portable unit transmits a response signal to indicate the user. When the user enters the detection area while all the doors are locked, an unlock standby state is set. When the user touches a touch sensor of a driver-seat side door under the unlock standby state, only the driver-seat side door is first unlocked. The other doors are kept locked if the user opens the D-door by the time when T2 seconds elapse. On the other hand, all the doors are unlocked when T2 elapses while the driver-seat side door is not opened.
