  • Publication number: 20160000954
    Abstract: An article and method are provided for assessing the efficacy of a sterilization process. The article comprises an outer container having an interior volume; a dry source of measurable biological activity disposed in the interior volume; and an effective amount of a dry agent for neutralizing a sterilant compound; wherein both the source of measurable biological activity and the agent are in vapor communication with an environment outside the outer container. The method comprises exposing the article to a first sterilant and, optionally, a second sterilant for a period of time and detecting the measurable biological activity.

  • Publication number: 20160005511
    Abstract: Sleeve (1) for a high- or medium-voltage power cable (120) having an inner conductor (130). The sleeve comprises (i) a tubular sleeve body (10) having an electrically conductive or semiconductive first axial electrode section (60), and (ii) a circuit board (30). The sleeve is radially expandable or shrinkable. It can be arranged radially outward of the inner conductor, such hat the first axial electrode section is radially separated from the inner conductor by at least an electrically insulating spacer layer (140). The circuit board is at least partially arranged radially outward of the sleeve body and comprises an electrical contact (100) which is electrically connected with the first axial electrode section.

  • Patent number: 9228117
    Abstract: Optically clear stretch releasing pressure sensitive adhesive films containing a silicone pressure sensitive adhesive composition and a tacky tab are provided. The pressure sensitive adhesive compositions are formed from elastomeric silicone polymer selected from the group consisting of urea-based silicone copolymers, oxamide-based silicone copolymers, amide-based silicone copolymers, urethane-based silicone copolymers, polydiorganosiloxane polymers, or mixtures of these copolymers. The pressure sensitive adhesive compositions may also contain an MQ tackifying resin. The pressure sensitive adhesive compositions may be used to form adhesive articles.

  • Patent number: 9229149
    Abstract: Optical constructions use a low index of refraction layer disposed between a low absorption layer and a high absorption layer to increase confinement of light to the low absorption region of the optical constructions. Low index layers can be used in optical constructions that have multi-tiered light confinement. In these constructions, a first tier of reflection is provided when light is reflected at the surface of a low index optical film which is disposed directly or indirectly on a light guide. A second tier of reflection occurs at the surface of a light redirecting film having appropriately oriented refractive structures.

  • Patent number: 9228665
    Abstract: Described are pressure fuses or pressure breakers which regulate the pressure downstream from the device. When the fluid pressure exceeds the trip pressure, the pressure fuse or breaker will trip and protect other components downstream of the fuse or breaker. Also described are methods of regulating pressure downstream from a fluid source using such fuses or breakers.

  • Patent number: 9232304
    Abstract: An ear tip is adapted to deliver sound to an ear canal. The ear tip includes a first section, a second section and a third section. The first section is connectable to a sound-transmitting device. The second section has a first end, a second end and walls defining a bulbous section. The first end is connected to and in open communication with the first section. The second end is connected to and in open communication with the third section. The third section includes walls defining a flume and an outlet port adapted for open communication with the ear canal. The outlet port has a maximum outer diameter of about 11 millimeters. In a relaxed state, a ratio of a maximum outer diameter of the second section to a maximum diameter of the third section is between about 1.25 and about 2.5.
