Abstract: An ultrasound scanning control method applied to an ultrasound scanning device is provided. The ultrasound scanning device includes an execution mechanism. The execution mechanism includes a mechanical arm and a probe. The ultrasound scanning control method includes controlling the mechanical arm to drive the probe to move according to a set scanning trajectory for performing an ultrasound scanning detection on a part to be examined. Once an actual pressure value between the probe and the part to be examined in each control cycle is sensed using the force sensor, a pressure value between the probe and the part to be examined is controlled to be a constant value based on the actual pressure value.

Abstract: A luggage includes a retaining device for easily hooking a handle of an auxiliary bag to the luggage. A retainer has one end pivotally secured to the front portion of the hook, and the other end movable toward the rear portion of the hook, for retaining the handle in the hook. A latch is slidably received in the hook for detachably securing the other end of the retainer to the hook, and thus for stably retaining the handle to the hook. The users may easily attach the handle of the auxiliary bag to the hook. A button may be used to disengage the latch from the other end of the retainer.

Abstract: A handle assembly includes a supporting bracket fixedly mounted on a top wall of a suitcase and including a base plate having two end portions each with a socket defined therein, and a side extension wall extending downwardly from one side of the base plate. Two receiving casings are each fixedly mounted on the side extension wall and each communicate with a corresponding socket. Two catches each formed on the side extension are each located in a corresponding casing. Two rotary drums are each rotatably received in a corresponding receiving casing and each have a plurality of teeth formed on an outer periphery thereof and each meshing with an associated catch.

Abstract: A retractable handle assembly includes a supporting bracket fixedly mounted on a top wall of a suitcase and including two end portions each having a socket vertically defined therein and a side extension wall extending downwardly from an underside thereof. Two receiving casings are each fixedly mounted on the side extension wall of the supporting bracket and each communicate with each of the two sockets. Two rotary cylinders are each rotatably received in a corresponding one of the two receiving casings and each have a passage radially defined therein and aligning with an associated socket. A U-shaped handle includes two upright legs each movably mounted on the supporting bracket and each slidably extending through a corresponding one of the two sockets and an associated passage. A handgrip has two distal ends each having a sleeve extending downwardly therefrom and fixedly mounted on an upper end of a corresponding one of the two upright legs.

Abstract: A retractable handle assembly for a suitcase includes a base disposed on an upper portion of the suitcase, an actuating device, a cover element and a handle. An outer tube is disposed on each side of the suitcase and extends between the base and the bottom of the suitcase with an inner tube retractably received in each of the outer tubes. Each of the inner tubes has a first end extending through the base and cover element and is attached to the handle. A resilient element is received in one of the inner tubes and has a protrusion extending radially through the cover element. The actuating device has a sliding element which is connected by a spring to a biasing portion. One end of the sliding portion is inserted into the cover element and an inner tube. One end of the biasing portion contacts the protrusion of the resilient element. When the actuating device is slid, it pushes the protrusion from the cover element and withdraws the end of the sliding portion from the cover element, freeing the inner tubes.
