Abstract: A stem cap audio system enables detachable attachment of a speaker assembly to the stem cap of a bicycle. A speaker base is configured to detachably couple to the stem cap. The speaker is coupled to the base and may be configured for easy one-hand operation, wherein functions of the speaker are initiated by simply pushing down on the speaker housing. The speaker housing is configured to actuate or depress down into the speaker base and a speaker control interface is actuated by contact with a portion of the base. An elastomeric interface is configured between the speaker and base to rebound the speaker after actuation to change a function of the speaker operation. This easy one hand operation can be operated while riding and with a gloved hand.

Abstract: Sampling or removing interstitial fluid of a subject using an implantable access chamber and associated methods of use. An implantable access chamber can be configured to be inserted into tissue of a subject. The implantable access chamber can comprise a sensor arranged therein, wherein the sensor is configured to sense at least one analyte of interstitial fluid of the subject. The implantable access chamber can include a barrier portion defining a cavity. The barrier portion may be a material permeable to the interstitial fluid and occlusive to cells of the subject.

Abstract: Novel catheter constructions comprising thin covering or wrapping materials such as polymer films. A catheter provided with a guidewire catheter lumen having a thin covering that is easily punctured by a guidewire at virtually any desired point along the catheter length. The thin covering may be integral with the catheter shaft, or may be a separate component that covers only the portion of the catheter shaft immediately adjacent the outer portion of the guidewire lumen, or may be a thin tubular construct that surrounds the entire catheter shaft. Moreover, polymer film can be used in combination with one or more elements to produce novel catheter constructions.

Abstract: Novel polymer shrink tubes, such as fluoropolymer shrink tubes and novel uses thereof. The polymer shrink tubes include at least one three-dimensional pattern formed along at least a portion of the inner surface of the tube. The polymer shrink tubes can be used for, for example, embossing a pattern into a polymer tube. Further use includes, for example, forming a catheter with at least one channel located in the catheter wall.

Abstract: A connector assembly incorporating a pressure relief valve is provided for connecting an inflatable article such as an inflatable garment or air mattress to a source of inflation air which presents a low profile during manufacturing and in use. The connector includes a semi-rigid, hollow connector housing having a first, generally tubular, insertable section, insertable through an opening in a flexible wall of the inflatable article. A second external section extends oppositely from the insertable section and outwardly from the flexible wall upon insertion, the external section and the insertable section are connected and oriented generally at an angle, preferably a right angle, with respect to each other.

Abstract: Puncturing tools that cause an aperture to be pierced through the wall of a guidewire lumen of a catheter shaft at a location at which it is desired to have a guidewire exit the guidewire lumen.

Abstract: A three dimensional porous elastomeric polymeric material is described that has a morphology primarily of polymeric fibers fused randomly along portions of their length, with a cross-section of a network of irregular polymeric areas that are interconnected to define interconnected voids; where the bulk density of the material is at least 0.35 grams/cc. The material is useful in garment and other protective covering applications where it can be adhered to various substrates to provide improved abrasion resistance. Composites of the material are described also.

Abstract: A computer system according to which a bracket supports a computer chassis on a structure having an accessible upper edge. The bracket is formed by a plurality of support members for receiving the chassis and for engaging the chassis in a manner to prevent movement of the chassis relative to the bracket. At least one hook is connected to the support member for extending over the edge to support the support member, and therefore the chassis, relative to the structure.
