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： 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： 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.

摘要： A hybrid expansion unit includes at least one digital communication interface adapted to communicate first and second sets of N-bit words of digitized spectrum with an upstream device. The hybrid expansion unit further includes at least one analog communication interface adapted to communicate first and second sets of bands of analog spectrum with a downstream device. The hybrid expansion unit is adapted to convert between the first set of N-bit words of digitized spectrum and the first set of bands of analog spectrum. The hybrid expansion unit is further adapted to convert between the second set of N-bit words of digitized spectrum and the second set of bands of analog spectrum. The first set of bands of analog spectrum occupy a first frequency range and the second set of bands of analog spectrum occupy a second frequency range. The first frequency range and the second frequency range do not overlap.

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： Information items in a file system are arranged into groups that are created according to a grouping component. A non-hierarchical view displays visual representations (e.g., icons, thumbnail images) of the information items arranged in visually delineated groups according to an arrange type that can be specified for each group. Various view formats are available including icon, list and column view formats. In each view format, a condensed mode can be selected for one or more groups, resulting in multiple visual representations of items being displayed in a fixed amount of screen space in the non-hierarchical view. In icon view, each condensed group includes a single row of visual representations that can be navigated separately from other groups in the non-hierarchical view.
