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 tamper deterring end cap for a bat. The bat includes a barrel, a taper, and a handle.

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 torque-limited fastener is for an electrical connector including an electrically conductive body having at least one fastener-receiving passageway intersecting a cable-receiving passageway. The torque-limited fastener may include a body being externally threaded to be received within the fastener-receiving passageway and having a tool-receiving passageway therein. A break-away head may be initially coupled to the body for breaking away therefrom at a torque limit upon tightening of the fastener. The break-away head may have a tool-receiving passageway therethrough aligned with the tool-receiving passageway of the body and accommodating a commonly-sized tool therein. At least one tool stop may extend inwardly in the tool-receiving passageway of the break-away head to restrict insertion of the commonly-sized tool for tightening to a torque limit, and being removed upon breaking away of the break-away head thereby permitting insertion of the commonly-sized tool into the tool-receiving passageway of the body to facilitate removal thereof.

A cigarette lighter with improved safety property includes a combustion chamber formed as a receptacle in which a cigarette to be lit is inserted. The receptacle is formed of three concentric vented tubes. The combustion chamber is shaped and dimensioned in a manner to completely envelop the flame produced in the combustion chamber, and to prevent any objects with dimensions larger than diameter of a cigarette to be received in the combustion chamber. A flame stabilizer is secured in the inner tube of the receptacle unit at a predetermined distance from the burner in order to limit the insertion of the cigarette and to prevent the unwanted extinction of the flame if the cigarette is inserted too close to the source of the flame.

Shielding for the protection of plants and seedlings from ground pests is provided. Shields can be comprised of materials including biodegradable materials that have the advantage of being formed into plant protection shields with various features, such as by an injection molding process, but that can be buried within the soil along with a plant's roots. Plant shields are provided for being partially buried in soil to surround a plant and for providing above-ground protection from ground travelling pests. Such shields can comprise a walled structure surrounding and creating an open-ended enclosure with the shield comprising an above the ground portion and a below the ground portion.

The above the ground portion and the below the ground portion can be divided from one another by a divider that extends along an external surface of the walled structure in a similar direction as the walled structure surrounds the enclosure, the divider element comprising a ground engagement surface for limiting insertion of the shield into the soil.

An insertion device and rectal tip assembly having a dual flex allowing for the safe and non-traumatic insertion and removal of tubing into a body cavity. The dual flex insertion tubing has a flexible part and a rigid base part wherein the soft flexible part provides sufficient play and support when inserting the tubing into a body cavity while the rigid part provides a supporting base for the soft flexible part of the tubing. A first tubular portion has a first flexural modulus wherein said first flexural modulus is sufficiently pliable to allow for repeated non-traumatic insertion and is in communication with a second tubular portion having a second flexural modulus sufficiently rigid to support the first tubular portion but also has a minimum bend radius that allows for sufficient play of the second tubular portion. The dual flex insertion device can be used with an enema, douche or colonic irrigation device or any other device used to introduce liquid into a body cavity. The dual flex insertion device can also be used alone or in combination with toilet attachments as described in U.S. Pat. No. 5,946,741, the disclosure of which is incorporated herein by reference.

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.
