  • Publication number: 20160050210
    Abstract: Various of the disclosed embodiments concern methods and systems for maintaining privacy in a machine directed workflow for the purpose of creating a set of authorized users. According to one embodiment, the system maintains privacy by dividing information associated with a user into three privacy tiers. First privacy tier is configured to authorize access to all users. Second and third privacy tiers are configured to limit access to a subset of users. Once the system matches the users and receives authorization from the users, the system creates a set of authorized users, which can freely send messages to each other, and share first, second and third privacy tiers of information with each other.

  • Patent number: 9181746
    Abstract: A locking mechanism for use with a window having a hinge coupling a sash to a frame includes a keeper and a locking lug. The keeper includes a generally planar base plate that is abutable to a surface of either the sash or the frame and two wings extending upwardly from the base, each of the wings having an upwardly and inwardly extending portion extending from the base plate and an inwardly extending portion extending inwardly substantially parallel to the base plate from the upwardly and inwardly extending portion. The two inwardly extending portions define a gap therebetween. The planar base further includes at least one self locating leg extending outward and coplanar with the base. The self locating leg adapted to abut a portion of the sash or the frame. Thus, the keeper is positionable without a fixture.

  • Publication number: 20150171816
    Abstract: There is disclosed a balun for dividing an input electrical signal to produce first and second output electrical signals which are substantially out of phase, the balun including: an input port for receiving the input electrical signal; an input line for coupling the input electrical signal to a slotline; and an output line for coupling the first and second output electrical signals to, respectively a first output port and a second output port, the output line having a junction with the slotline; wherein the slotline couples the input electrical signal to the junction, and the junction acts as a divider to produce the first and second electrical signals; in which at least one of the input line, slotline and output line has a width and a length wherein the width varies over the length.

  • Publication number: 20140325914
    Abstract: A device to limit an opening of a window having a sash selectively movable between a window closed position in which the sash is received in a window frame, and a window open position in which the sash is pivoted outwardly relative to the window frame. The device includes a sash bracket, a limiting arm assembly with an engagement structure, and a securing structure with a selectively operable release mechanism. The securing structure receives the engagement structure of the limiting arm assembly so that the limiting arm inhibits pivoting of the sash toward the window open position beyond a distance of travel defined by a length of the limiting arm, and the engagement structure is releasable from the securing structure by operating the release mechanism so that the sash can be further pivoted toward the window open position beyond the distance of travel.

  • Patent number: 8813424
    Abstract: A device to limit an opening of a window having a hinged sash coupled to a window frame including a window opening limiting structure having a first member and a second member. One of them is securable to the sash and the other of the first member and the second member being securable to the frame. A selectively releasable coupler by which the first member and the second member are couplable is shiftable between a coupled status and a released status. The first member and the second member bridge a preselected distance such that the sash is inhibited from opening beyond a predetermined distance. The coupler is releasable so that the sash can be opened beyond the predetermined distance and re-engages automatically when the sash is closed.

  • Patent number: 7031117
    Abstract: Assemblies in accordance with the present invention can access a data storage medium having one or more disks. One such assembly comprises a mounting block including a bore and spacer, an arm stack connected with the top surface of the spacer, and a bottom arm connected with the bottom surface of the spacer. The arm stack comprises module(s) stacked on a top arm. The arm stack and bottom arm are designed such that either can be disconnected from the mounting block without disassembling the bore. By having a removably fastened arm stack and bottom arm, the assembly can be built at a relatively low cost without deformation. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
