    摘要: An intelligent distributed antenna system is disclosed which improves upon known distributed antenna systems particularly with respect to identifying failures or anomalies in the system. The disclosed system includes a signal source, a master unit, and one or more remote units each connected to antennas for transmitting radio frequency signals to terminal units and each connected to the master unit through fiber. The remote units, the master unit, or both may include power signal readers. The remote units may be configured to determine a point of failure in the system based on the power measured from reflected signals. The master unit can be in communication with the remote units to generate alarms and reports as well as to control the system in response to detection of a failure or anomaly.

    摘要: A wiper blade is presented having a wiper strip, a primary frame, and a pair of secondary frames. The primary frame having a connection device capable of connecting the wiper blade to a wiper arm disposed on a top side of the primary frame, and a connection structure disposed, on opposite ends of the primary frame. The pair of secondary frame, each have a central pivot connection portion and two leg portions extending from the central pivot connection portion, a pivot structure disposed on the central pivot connection portion of the secondary frames wherein the pivot structure of the secondary frames are connected to the connection structures on the ends of the primary frame. A wiper blade is also presented having a wiper strip, a force distribution structure having opposite ends, and a cover.

    摘要: A wiper blade connector releasably secures a wiper blade to a wiper arm, thereby forming a windshield wiper blade assembly. The wiper blade connector comprises an elongate body member having opposite facing side walls, a front end, and a rear end. The opposite facing sidewalls include means for receiving and releasably securing to the mounting base on a wiper blade. At the front end of the elongate body member, a first tongue receiving opening is sized to receive the corresponding front tongue of a wiper arm. At the rear end of the elongate body member, a second tongue receiving opening is sized to receive the corresponding rear tongue of a wiper arm. A locking mechanism, such as a slidable cap provided proximate to the front end of the elongate body member, releasably locks the wiper blade member to the wiper arm.

    摘要: A sighting system for a firearm, configured for securing, about a firearm, the sighting system housed in a housing, with a smart phone or smart device mounting platform rotatably coupled thereon, with an additional rear viewing camera, integral or attachable to an armature. This said armature, additionally passes through an open portion of a clamping device, that is attachable to a threaded base portion, of the back side of said smart device mounting platform, and is both height and angularly adjustable. This said sighting device, provides the target image that is either received from other target viewing devices mounted on the firearm, or provides its own target image, to the smart device, where this said target image is viewable by the user, from any position that the user could position himself in relation to the firearm, by means of the said rotatable smartphone or smart device mounting platform. The image of the area behind the user would also be provided at the same time, by means of the said height and angularly adjustable rear viewing camera, that would either display its image simultaneously in a window of, or on, a split screen on the smart, device's viewing screen, or would provide the image behind the user simultaneously, in its own viewing screen.

    摘要: A thin-film interference filter has a thin-film interference multi-layer stack composed of individual thin-film layers arranged in groups to form a plurality of repeat unit blocks. The thin-film interference filter is flexible enough to be bendable to a radius of curvature of 250 mm or even less without permanently damaging the thin-film interference filter. The thin-film interference filter may have a second thin-film interference multi-layer stack composed of individual thin-film layers arranged in repeat unit blocks may have a different optical transmission spectrum. At least one interlayer between the first thin-film interference multi-layer stack and the second thin-film interference multi-layer stack may block a range of wavelengths of infrared, visible, or ultraviolet light. A defect layer of a different optical thickness than neighboring thin-film layers forming the repeat unit blocks, thereby creating a Fabry Perot resonance cavity.
