    摘要： Automated detection of structure is provided in ultrasound M-mode imaging. A coarse and fine search for structure is used. For example, a less noise susceptible initial position or range of positions for a given structure is determined. This position is then refined. The coarse positioning and/or the refined position may use machine-trained classifiers. The positions of other structure may be used in either coarse or fine positioning, such as using a Markov Random Field. The structure or structures may be identified in the M-mode image without user input of a location in the M-mode image or along the line.

    摘要： A method and system for determining a scan range for a magnetic resonance (MR) scan is disclosed. A plurality of 2D localizer images are received. A most likely position is detected in each localizer image for each of a plurality of anatomical landmarks associated with a target organ in each localizer image. A scan range is determined based on the detected most likely positions of each anatomic landmark in the localizer images.

    摘要： Methods and apparatus for expanding a rod from a collapsed position to a formed position are disclosed. One such apparatus includes a plurality of segments for forming the body of the collapsible rod including with each segment coupled to each immediately adjacent segment of the plurality of segments. The apparatus may include a coupler for coupling each segment of the plurality of segments to each immediately adjacent segment of the plurality of segments. The coupler may stretch from a base segment to the tip of the apparatus and may be biased to apply a force to hold the plurality of segments in a formed position and to urge the plurality of segments into a formed position from a collapsed position. In the formed position, the plurality of segments may be aligned end-to-end to form a rod and in the collapsed position, the plurality of segments may be folded against each other such that cylindrical walls of each of the plurality of segments are positioned adjacent each other.

    摘要： A convertible bullet-proof backpack and vest includes a body section divided into a front portion, a middle portion, and back portion. The middle portion has a head slot opening, and the front and back portions have respective sections of bullet-proof fabric integrated therein. A zipper runs around an outer perimeter of the front and back portions. In a backpack configuration, the front portion and the back portion fold toward each other and the zipper secures the outer perimeters of the front portion and the back portion together thereby forming a hollow backpack interior between them. In a bullet-proof vest configuration, the zipper is unzipped thereby allowing a user to insert their head through the head slot opening such that the front portion hangs in front of a torso of the user and the back portion hangs behind the torso of the user.

    摘要： The present invention strategically utilizes the sturdiness of thin wires enwrapped inside a thick layer of soft material such as silicone rubber which is smoother and softer than human tissue. Therefore, the device doesn't cause any damage or side effect and feels comfortable to user. The exposure of skin is 90% or higher, therefore solves the lack of sensation issue faced by prior art devices. The device is hard and yet flexible, the side walls or double bars are positioned toward ventral side of the device so that it is pleasing to the eye during use in addition to feeling good by the user.

    摘要： A photovoltaic cell has an active area formed electron donor-fullerene conjugated molecules. The electron donor is formed of a polymer, which is conjugated with an electron acceptor, such as fullerene. By conjugating the fullerene, such as C60, with electron donor moieties, such as that of the polymer, double channels are formed therebetween, whereby one channel provides hole transport and the other channel provides electron transport. As a result, the electronic coupling between the fullerene and the electron donor moiety leads to increased short-circuit current density (Jsc) and increased open-circuit voltage (Voc), resulting in high power conversion efficacy (PCE) in the solar cell.
