Abstract: A multi-antenna structure may include a monopole and a first antenna array connected to the monopole at a first location via a first mounting apparatus and including a first cellular antenna and a first radio unit. The structure may also include a second antenna array connected to the monopole at a second location via a second mounting apparatus, with a second cellular antenna and a second radio unit. The structure may include a first set of fronds arranged about an outer surface of the monopole, forming a first respective angle with the monopole and configured to obscure the first antenna array from view. The structure may include a second set of fronds arranged about the outer surface of the monopole, each of the second set of fronds forming second respective angle with the monopole. The second set of fronds may be configured to obscure the second antenna array from view.

Abstract: According to one aspect, a mechanism for wirelessly adjusting tension of an article includes a tension input component that is coupleable with a vehicle in an area that is easily accessible to a user. The tension input component is configured to receive input from the user corresponding to an adjustment of a motorized tensioning device that is attached to the article and that is configured to adjust a tension of a tension member. The tension input component is configured to wirelessly transmit the received input to the motorized tensioning device. Adjustment of the tension member tightens or loosens the article in accordance with the input received from the tension input component.

Abstract: A method of forming a cooling hole in a workpiece that includes the steps of laser-forming a blind, inwardly-tapering transition opening into a first side of the workpiece, and EDM-forming a generally cylindrical through hole to a second, opposing side of the workpiece communicating with the inwardly-tapering transition opening to form a through cooling hole communicating with the first and second sides of the workpiece. An airfoil having cooling holes formed by use of both laser and EDM is also disclosed.

Abstract: An embodiment of the invention is an optical interconnect module comprising a silicon carrier; a communication integrated circuit mounted on the silicon carrier and an optical integrated circuit flip chip mounted on the silicon carrier. The optical integrated circuit is in electrical communication with the communication integrated circuit by electrical paths in the silicon carrier. Optical paths in the silicon carrier provide optical coupling between the optical integrated circuit and an optical link.

Abstract: A monolithic semiconductor optical detector is formed on a substrate having a plurality of substantially parallel trenches etched therein. The trenches are further formed as a plurality of alternating N-type and P-type trench regions separated by pillar regions of the substrate which operate as an I region between the N and P trench regions. First and second contacts are formed on the surface of the substrate and interconnect the N-type trench regions and the P-type trench regions, respectively. Preferably, the trenches are etched with a depth comparable to an optical extinction length of optical radiation to which the detector is responsive.
