A fiber optic ferrule, preferably an MT-type ferrule, and connector design is provided that includes a unitary v-groove lens array (v-lens). The v-lens comprises a plurality of lenses and corresponding plurality of open v-grooves to align optical fibers with the plurality of lenses. Because the v-groove lens array is a unitary structure, high precision manufacturing is required for only the v-groove lens array, and not for other components forming the ferrule. A housing holds the v-groove lens array and preferably comprises a cantilever configured to retain the optical fibers substantially within their corresponding v-grooves. An opening in the housing allows an adhesive to be placed in contact with the housing, optical fibers and v-groove lens array thereby retaining the various components in a fixed relationship. A fiber optic connector may include the fiber optic ferrule in accordance with the present invention disposed within a suitable connector housing.

The present invention relates generally to the field of treatments for nasal congestion, and in particular, to a method and apparatus for alleviating nasal congestion in a patient by mechanically stimulating the sneezing reflex in the patient to urge drainage of the nasal passageways. The method includes inserting an instrument having a work tip portion provided with at least one filament into the nostril of the patient. The nasal mucosa of the patient is then probed with the at least one filament to stimulate in the patient the sneeze reflex. This probing action causes the patient to sneeze. With the patient's mouth closed, the sneeze urges at least one of mucus, fluid and debris in the nasal passages of the patient to be forcibly expelled through the nostrils of the patient thereby draining the nasal cavity of the patient. The instrument used in the performance of this method includes a handle portion upon which the work tip portion is carried. The handle portion may be integrally formed with the work tip portion or releasably attachable thereto. The instrument is further provided with a physical stop associated with one of the work tip portion and the handle portion to prevent injury resulting from the working tip portion being inserted too deeply into the nasal passages of the patient.

A needle device for penetrating body tissues while substantially reducing the risk of damage to blood vessels and body organs by using visual control of the operative tip during insertion and the procedure, is disclosed herein. The needle device of the present invention has a large and diverse applicability to a number of medical procedures by enabling internal visual inspection of body tissues and cavities during treatment without open surgery or supplemental penetrating or visualization devices.

A jack for receiving and connecting with a compatible plug, the jack including a housing having a plug-receiving chamber therein, the housing having an orifice through which the plug is insertable into and removable from the chamber, and a pivotable prebiased door having a closed position generally disposed over the orifice when the plug is not disposed within the chamber and an open position not generally disposed over the orifice when the plug is disposed within the chamber, the door including a projecting portion for limiting the extent of insertion of the plug into the chamber.

A connection assembly for pipes is provided. The assembly includes a pipe, a corrugated conduit, a circumferentially contractible seal positioned between portions of the conduit and the pipe, a clamp encircling the conduit, seal and pipe, and a plurality of discrete projections on the inside of the seal to limit the extent of overlap between the pipe and the conduit. The seal is circumferentially contractible to secure the conduit and the pipe together with the seal serving to effect a gas-tight seal while filling the annular gap between the conduit and pipe.

A lever connector that exhibits excellent space efficiency is provided. The lever connector includes female and male housings that are engageable with each other. A lever is mounted displaceably on the male housing and can be moved between an initial position and a fitting position. A cam groove is formed on the lever, and a cam follower is formed on the female housing. An entrance of the cam groove is aligned in a direction that intersects the fitting direction of the housings when the lever is at the initial position, and the female housing is assembled into a hood along the same direction.

A dual axes swivel connector for connecting various panels to assemble a pet enclosure is disclosed. The dual axes swivel connector allows panels of the enclosure to be reliably pivoted with respect to each other. The dual axes swivel connector may comprise first and second parts. The first part may be fabricated from a flexible material compared to the second part, whereas the second part may be fabricated from a more rigid material compared to the first part. The flexibility of the first part allows the first part to have a tighter fit with the wire rods. The second part has a looser fit with the wire rods but the rigidity of the second part compensates for the looser fit. When the first and second parts are interlocked, they create a tight fit which can reliably provide a hinge between the panels.

The fueling device has a fueling pipe adapted to supply fuel pumped from the inlet opening the fuel tank. A grating member is situated inside the fueling pipe. The grating member includes an annular body positioned substantially concentrically with the fuel passage; and a support body adapted to support the annular body on the inside wall of the flow passage. Gaps present between the inside wall of the passage-defining member and the annular body and the support body constitute part of the fuel passage.

A cable support is provided that includes an elongate support member for supporting a cable or cables secured thereto. A mounting member is connected to the support member and secures the support member to amounting stud on a trim panel or other support substrate. The mounting member comprises a bore for receiving the mounting stud. A locking member is provided that has an aperture formed therein for receiving the mounting stud. The locking member is connected to the mounting member in axial alignment with the bore and rotatably connected to the mounting member such that the mounting member and support member are rotatable relative to the locking member.

An improved system for capacitive testing electrical connections in a low signal environment. The system includes features that increase sensitivity of a capacitive probe. One feature is a spacer positioned to allow the probe to be partially inserted into the component without contacting the pins. The spacer may be a collar on the probe that contacts the housing of the component, contacts the substrate of the circuit assembly, or both. In some other embodiments, the spacer may be a riser extending beyond the surface of the sense plate that contacts the component, a riser portion of the component, or a combination of both. The spacer improves sensitivity by establishing a small gap between a sense plate of the probe and pins under test without risk of damage to the pins. A second feature is a guard plate of the probe with reduced capacitance to a sense plate of the probe. Reducing capacitance also increases the sensitivity of the probe.

A cable support is provided that includes an elongate support member for supporting a cable or cables secured thereto. A mounting member is connected to the support member and secures the support member to a mounting stud on a trim panel or other support substrate. The mounting member comprises a bore for receiving the mounting stud. A locking member is provided that has an aperture formed therein for receiving the mounting stud. The locking member is connected to the mounting member in axial alignment with the bore and rotatably connected to the mounting member such that the mounting member and support member are rotatable relative to the locking member.
