摘要： This invention provides a method and system for distributing multiband wireless communications signals. Downlink RF signals in a plurality of downlink frequency bands are received and then combined into a combined downlink RF signal at the main unit. The combined downlink RF signal is subsequently split into multiple downlink RF-parts, which are converted to multiple downlink optical signals and optically transmitted to the remote units. At each remote unit, a delivered downlink optical signal is first converted back to a downlink RF-part which is subsequently separated into a plurality of downlink RF-groups by frequency band. Each downlink RF-group is individually conditioned (e.g., filtered and amplified). The individual-conditioned downlink RF-groups are then combined and transmitted to a dedicated downlink antenna.

摘要： In an orthotic walker, mechanism is provided to bias alternate motion of a user's legs. The mechanism may be a reciprocating bar at hip level, or at least one strap ends of which are attached to leg braces and the bight passing round a fixed frame member. A stirrup mechanism may be pivoted at an "ankle joint" and the pivotal motion may be limited to avoid toe down position. The stirrup may have a clamp for a shoe. Brake mechanism may be movable between operative and inoperative positions. In the operative position rearward rolling is disallowed while forward motion is allowed.

摘要： A reciprocating gait orthosis or prosthesis to provide a natural and efficient method of ambulation for paraplegic patients comprises hip joints which are coupled by a single push/pull member in the form of an inner metal cable which is surrounded by two nylon tubes, the outer nylon tube being a tight fit on the inner nylon tube which, in turn, closely embraces the inner metal cable so that they all move together, the arrangement also comprising two limb members each having a respective hip joint at one end and a respective knee joint at the other end with the joints rotatably coupling the limb member to further members which are pivotally coupled to a tie rod whereby rotation of the further members relative to the limb member about the joints is coordinated by the tie rod, there also being a spring which acts to urge the arrangement into a standing position and controls movement into a sitting position.

摘要： A wellbore tool includes a rod with a plurality of rod sections. The rod is configured to be placed within a wellbore casing of a low-pressure hydrocarbon well. A plurality of sealing elements are positioned at a downhole end of the rod. Each sealing element is configured to provide a gas-tight seal between the sealing element and an inner wall of the wellbore casing. A handle positioned at an uphole end of the rod provides a hand grip for a user of the wellbore tool.

摘要： User interface changes and file system operations related to grouping items in a destination folder are disclosed. A user can group multiple items displayed on a user interface into a destination folder using an input command. An animation can be presented in the user interface illustrating the creation of the destination folder and the movement of each selected item into the newly created folder. The movement of each selected item can be along a respective path starting from an initial location on the user interface and terminating at the destination folder, and initiation of the movement of each selected item can be asynchronous with respect to the other selected items. Implementations showing the animations in various types of user interfaces are also disclosed.

摘要： One embodiment is directed to a distributed antenna system in which a setting for automatic gain control functionality in at least one unit included in the system (for example, in a hub unit or a remote unit) is determined by interpolating between two detected levels measured at that unit while the automatic gain control functionality is operating in two respective predetermined configurations and by interpolating between two target levels that are associated with the two respective predetermined configurations. In one example, the intersection of the two resulting interpolations is used to determine the setting for the automatic gain control functionality.

摘要： Planarization methods for maintaining planar surfaces in the fabrication of such devices as BAW devices and capacitors on a planar or planarized substrate are described. In accordance with the method, a metal layer is deposited and patterned, and an oxide layer is deposited using a high density plasma chemical vapor deposition (HDP CVD) process to a thickness equal to the thickness of the metal layer. The HDP CVD process provides an oxide layer on the patterned metal tapering upward from the edge of the patterned metal layer. Then, after masking and etching the oxide layer from the patterned metal layer, the patterned metal layer and surrounding oxide layer form a substantially planar layer, interrupted by small remaining oxide protrusions at the edges of the patterned layer. These small remaining oxide protrusions may be too small to significantly disturb the flatness of a further oxide or other layer or they may be further mitigated by the application of another HDP CVD oxide film.
