The present invention provides a pin and tumbler cylinder lock and a retrofitted cylinder lock which minimizes unauthorized openings of the lock by bumping. The cylinder lock utilizes specially designed driver pins which are correlated in size to the largest possible stack height of the tumbler pins with a bump key inserted in the plug portion of the lock and the shear line height of the lock. All the driver pins are about the same height and preferably symmetrical with a lip on each end. The invention also provides a method for retrofitting existing locks by removing at least one of the driver pins and replacing the removed driver pin or pins with the driver pins of the invention.

An electronic device includes a housing and a catheter having a proximal end seated within the housing and a distal end positioned to an exterior thereof. The catheter distal end has an arcuate shape, assisting the user to scan an internal plug cavity, and a cylindrical cross-section provided with a suitable diameter such that the catheter can be probed through a lock plug without contacting pin pairs. A mechanism is included for detecting a point where the pins come together and line up with a shear line. LEDs are coupled to the detecting mechanism and are illuminated when the catheter is displaced along the lower and upper pin pairs. A mechanism is included for automatically adjusting the catheter's position as the point of each of pin pair is detected. A mechanism is included for displaying numeric values on the housing that correspond to the points identified by the detecting mechanism.

The invention provides an ultrasonic imaging method used for carrying out 3D imaging on the endometrium. The method includes the steps that a uterus 3D ultrasonic image containing the endometrium is acquired; the ultrasonic image is rotated so that the endometrium part in the ultrasonic image can be rotated to be horizontal; an ROI shear line is adjusted to axially correspond to the endometrium image; an endometrium 3D image extracted according to the adjusted ROI shear line is acquired. The invention further provides a corresponding device and ultrasonic equipment. By the adoption of the method, after a doctor acquires the uterus 3D ultrasonic image containing the endometrium, the ultrasonic image is rotated to make the endometrium image horizontal, then the shear line is adjusted to axially correspond to the endometrium, and thus the endometrium 3D image is automatically acquired; operation time is greatly shortened, and the operation process is simplified.

A locking device and system are disclosed. The locking device includes a barrel within which sets a plug. A plurality of pins sit in pin pathways that extend partially through the barrel and plug and the pins prevent rotation of the barrel within the plug when the ends of the pins are not aligned with a shear line. One of the pins has a recess formed therein within which a locking ball can sit. The engagement or otherwise of the locking ball in the recess is controlled by a linear actuator. When the linear actuator allows the locking ball to disengage the recess the pin with the recess in can engage the key and a line the end of the pin with the shear line.
