Abstract: A system for transferring an object from one user to another user that is useful to prevent unintentional dropping of the object is disclosed. A cam is rotatably connected to a structure that is configured to be attached to a first user. A central housing with two ports is configured to allow for the attachment of a tool by lanyard or other means. When the first cam is locked into the one of the housing ports, it cannot be released from the housing unless a second cam is inserted into the second housing port and captured. Once the second cam is captured the first cam is released, thus safely passing the tool from the first user to the second user while minimizing the chance of dropping the tool.

Abstract: A protective cover assembly having a tray having a concave surface and a perimeter, the concave surface defining a volume sufficient to accommodate a portable electronic device; and an elastomeric collar having an internal rim that reversibly engages and wraps around the perimeter of the tray.

Abstract: The system incorporates wire deflection, taut wire detection for perimeter security applications. Generally, the system of the invention provides intrusion detection by an internal mechanism. The internal mechanism can detect wire deflection in any direction. In turn, given a sufficient amount of wire deflection, a security system is signaled. However, the force required to sufficiently deflect the wires is high enough so as to minimize nuisance alarms. The internal mechanism is generally held within a structure so that it is protected from tampering. As such, the internal mechanism is also kept separate from the wire array so that it is protected from attempts by an intruder to isolate the wire array.

Abstract: A friction hinge includes a socket made up of a compressible elastomer insert sleeve inside a relatively rigid cup substrate. The insert sleeve defines an opening with a lip around the opening, and a relatively rigid ball or other center portion can be snap assembled through the lip and opening to center itself in the socket. A mount portion extends through the opening off the ball/center portion, and hand pressure on the mount portion can adjust the angular position of the joint. The size of the ball/center portion relative to the size of the cup substrate causes dimensional compression of the insert sleeve, such as about 15% of its thickness. The compression of the insert sleeve creates a controlled friction force on the ball/center portion, so the snap assembly friction hinge works consistently over a long time and over wide temperature ranges.

Abstract: A fence post assembly, as well as a fencing system and related method utilizing the fence post assembly, for forming a temporary enclosure, such as a horse corral for restraining horses. The fence post assembly is provided with an extensible and retractable fence strand, such as polytape or wire, as well as a ground anchor at one end of the post to enable the post to be anchored into the ground. The extendable and retractable fence strand is selectively positionable along the length of the post between the first and second opposite ends thereof. In addition, the fence strand can be electrically conductive to permit the enclosure to be electrified. Provision is made to maintain electrical continuity between fence strands.

Abstract: The invention is directed to devices and methods for tissue dilators. The present invention encompasses a large variety of discrete structure, all intended to be applied externally to a subject for the purpose of dilating, or lifting, tissue adjacent to nasal passageways of the subject, including the vestibule and/or the valve of the subject so as to decrease resistance to inhalation and exhalation of said subject during respiration. The dilator comprises an alignment feature which is aligned with the uses nasal ridge during application to ensure a proper application.

Abstract: A pneumatic control device includes a housing, a pressure control member secured to the housing, a first fluid-conduit member, and a first sensor. The pressure control member is constructed and arranged to selectively change a fluid pressure within the control member. The first fluid-conduit member is in fluid-flow communication with the pressure control member. The first sensor is in fluid-flow communication with the first fluid-conduit member. The sensor is constructed and arranged to generate a control signal based upon the fluid pressure within the control member. In preferred systems, the pneumatic controller is useful for producing a variable control signal to control a rate of fluid dispersement to a patient in an angiographic system.
