Device and methods for strengthening and toning the abdominal and gluteal muscles. A seat is mounted in a fixed position on a base, and a back is pivotally mounted for movement about an axis toward the rear of the seat, with springs or elastic cords yieldably urging the backrest to pivot in an upward direction toward a raised position. To strengthen and condition the upper, lateral and oblique abdominal muscles and gluteal muscles, an exerciser rests upon the seat, with his back against the backrest, and the elastic cords or springs assist him in raising his back and also allow him to extend to the full range of backward motion while absorbing the impact of that motion. To exercise the lower abdominal muscles and gluteal muscles, the exerciser reclines on the seat, with his legs on the backrest and the elastic cords or springs assisting him in raising his legs and absorbing the impact of lowering them.

Provided is an interchangeable makeup brush including: a plurality of brush tips fixing a brush; and a brush rod having the brush tip detachably coupled thereto, and being grasped by a hand of a user, wherein the brush tip includes a mounting protruding portion formed at a rear thereof which is inserted and coupled in the brush rod. According to the present invention, a brush tip may be attached and detached to and from a brush rod, enabling convenient use when applying makeup by selecting and mounting a required brush, and allowing only one brush rod to be provided for economical advantage and ease of portability and storage.

This is a training device for soccer players that uses a plurality of connectors that have a main body and three hollow engagement ports that are angled away from the main body to provide support for the frame. The ends of the frame members fit into the engagement ports and thus engage the frame and support it for use. There is a flexible outer covering that fits over the frame members and supports the ring members that are placed within an opening in the outer covering. There can be one or two rings as desired. The outer covering does not cover the bottom of the frame, and this area can also be used as a target area.

The embodiment of the invention provides an image frame prediction method and a device as well as avatar display equipment. The image frame prediction method comprises the following steps: performinginterframe motion vector calculation on two adjacent source frames, so that a frame motion vector of the two adjacent source frames is obtained, wherein the source frames are rendered frames; according to at least two frame motion vectors, performing interframe motion vector prediction, so that a predicted value of the frame motion vectors is obtained; and according to the predicted value of the frame motion vectors, processing a source frame the nearest to the predicted value of the frame motion vectors, so that a predicted frame is obtained.

An air fire lighter having fuel, an igniter and a ducted fan for igniting a solid fuel fire. The fuel travels through the fire lighter to a collar at a distal end of the fire lighter, transforming into a vapor that is ignited by an igniter. As the solid fuel begins to glow at the initiation of the fire, the fan is activated, shutting off the vapors from the fuel. The fan blows air through a chamber onto the fire, causing the fire to spread throughout the solid fuel, establishing and spreading the fire through an ignition period. The chamber has a volume and ducting for providing optimal airflow to the fire. The fan is battery-operated. The lighter is lightweight and compact with a swiveling handle that adjusts for optimal placement of the lighter for addressing the solid fuel, folding for portability and storage.

A portable gym structure that is light weight and allows variable arrangement is disclosed. The portable gym structure is comprised of climbing walls and feet anchors for stability. The portable gym structure has variable configurations for different ages and abilities. The portable gym structure includes climbing walls that can be used for a slide or can be interchanged to be a climbing wall with variable climbing pieces.

A diaper changing system utilizes a diaper holder member on which a diaper is to be positioned. Flaps extend outward from the holder member and are foldable over the diaper to maintain it in position on the holder member. The system also includes a unique baby supporting pad configured to be placed on the user's lap. The supporting pad can be utilized to maintain a diaper or in combination with the holder member supporting the diaper. A strap circumscribes the leg of the user to maintain the holder member and supporting pad on the user's leg. Once the supporting pad and / or the holding member, with diaper attached, is secured on the user's leg, the baby is placed on the diaper. The diaper is then wrapped around the baby and secured. The baby is removed from the system's components, which are then folded and compacted for storage and transport.

The invention discloses a rotating disk microfluidic concentration measurement device and method based on photometric detection. A rotating disk microfluidic chip, a photometric detection device bracket, and an AC servo motor are arranged inside a sealed dark room, and the output shaft of the AC servo motor is vertical to the motor axis. A horizontal rotating disk microfluidic chip is installed upward and coaxially. The rotating disk microfluidic chip is equipped with an N-level test solution interpenetration zone, and each level of test solution interpenetration zone is based on the center It is an arc shape in the center of the circle, and the spring-like test solution flow channel between the adjacent two-stage test solution interpenetration zones is connected and communicated; the rotating disc microfluidic chip is used in combination with the rotating dilution positioning technology to realize the effective positioning of the dilution concentration, thereby Quickly calculate the dilution ratio, and multiply the dilution ratio by the corresponding relationship between the known optical path and the optimal concentration to generate the absorbance to deduce the precise concentration of the liquid to be tested. The process of sample injection, detection, and concentration calculation are all automated.

A diaper changing device utilizes a baby supporting member having a supporting surface on which a diaper is to be positioned, naps extend outward from the supporting member and are configured to be foldable over the diaper placed on the supporting surface to maintain the diaper in position on the device. Straps are provided to circumscribe the leg of the user, i.e. the diaper changer, and to maintain the device on the changer's leg. Once the device is secured on the user's leg, the baby is placed on the diaper. The diaper is then wrapped around the baby and secured, all while the baby is positioned upon the device.

The present disclosure relates to an easily foldable soft box, a lighting device that softens and spread light over a wide area, that comes with a diffuser (diffusing cover) that can fold easily with one touch, making it easy to collapse (and expand) the device. The easily foldable soft box comprises: a speed ring having the shape of a ring that allows a light-producing device to be mounted at an opening in the center, whose front part is configured to fold in half or unfold; a plurality of ribs attached to the front part, that are arranged in a radiating pattern around the speed ring when the front part is unfolded, and that are gathered together as the ribs arranged within one range overlap the ribs arranged within another range when the front part is folded in half; and a diffuser that unfolds like an umbrella to diffuse light produced by the light-producing device when the ribs are arranged in a radiating pattern, and that is folded by the ribs when the front part is folded.
