Abstract: This application discloses a multi-antenna system and a wireless communication device. The multi-antenna system includes a first antenna, a second antenna. A first extension branch is close to the second antenna, and a second extension branch is close to the first antenna. A feed of the first antenna is disposed on the first radiator, and a feed of the second antenna is disposed on a second radiator. A feed of the third antenna is disposed at the first extension branch. There is a spacing between the first extension branch and the second extension branch. An equivalent circuit of the spacing includes a distributed capacitor. The distributed capacitor is configured to isolate signal coupling between the first antenna and the second antenna when a first resonant frequency of the first antenna and a second resonant frequency of the second antenna are within a preset frequency range.

Abstract: A Wi-Fi and Bluetooth combined antenna apparatus and a configuration method therefor, and a terminal device. The Wi-Fi and Bluetooth combined antenna apparatus includes a Wi-Fi antenna, a ground plate, a perturbation unit, and a Bluetooth antenna. The Wi-Fi antenna generates a ground plate current on the ground plate; the perturbation unit is configured to generate a reverse current after being excited by the ground plate current, and a current zero point area is formed on the ground plate after the reverse current is superimposed with the ground plate current; and the Bluetooth antenna is disposed at a position of an edge of the ground plate corresponding to the current zero point area. In this way, isolation between the Bluetooth antenna and the Wi-Fi antenna is better improved.

Abstract: Embodiments of this application disclose a terminal antenna and an electronic device, and relate to the field of antenna technologies, which can better cover a medium-high frequency band, provide a good bandwidth and good radiation performance, reduce hardware costs, and have a good SAR, thereby better supporting a wireless communication function of the electronic device. A specific solution is as follows: The terminal antenna includes: a first radiator, a feed point, and a ground point. One end of the first radiator is grounded by using the ground point, and the other end of the first radiator is provided with the feed point. The first radiator is further provided with a slot that penetrates the first radiator, the slot is of an interdigital structure, and there are at least two slots.

Abstract: A medical imaging study comprising a plurality of medical images having been acquired by an imaging apparatus for a given patient are received, and a plurality of data arrays representing the plurality of medical images are generated. A request to display a given image is received from a client device. Benchmark testing with the client device is performed to obtain an indication of a performance of at least one of the client device and a communication link. A given compression algorithm from a set of compression algorithms is selected based on the indication of the performance, and used to compress a set of data arrays comprising a representation of the given image to obtain a set of compressed arrays. The set of compressed arrays are transmitted to the client device, the set of compressed arrays comprising the representation of the given image to be generated by a browser application.

Abstract: A method and system for processing imaging data of a tissue in an individual following a change in oxygenation or blood flow in tissue, for assessing tissue function. Test images are registered with a baseline image, providing registered images. The registered images may be compared to assess variations in the change in the tissue in response to changes in oxygenation or blood flow of the tissue shown in the images. The change in oxygenation or blood flow in the tissue may be quantified and plotted in a parametric plot or displayed in a parametric map to assess whether the change in oxygenation or blood flow, corresponding to a change in signal intensity, is abnormal following a stress event or under other conditions, to assess microvascular or macrovascular function.

Abstract: A portable electronic device having an illuminated keyboard includes a display having a recessed portion and a main body pivotally connected with the display. The main body includes a casing, a keyboard, a fastening element, and a plurality of light-emitting elements. The keyboard is disposed at the casing and includes a plurality of keys made of a first light-transmitting material. Each key has a light incident surface and a light output surface. The fastening element is fastened to the casing and has a first portion made of a second light-transmitting material. The fastening element corresponds to the recessed portion. The light-emitting elements are disposed in the fastening element. The light emitted by the light-emitting elements passes through the first portion of the fastening element to directly enter into the key through the light incident surface and to be outputted from the key through the light output surface.
