Abstract: Symmetric and asymmetric cyclic silalkylenesiloxane monomers and copolymers thereof, as well as crosslinked and/or reinforced silalkylenesiloxane copolymers, medical devices containing such materials, and methods of preparation.

Abstract: An implantable medical device determines activity levels over a set of time periods, preferably on the order of seconds, minutes and hours and a display is enabled for days or weeks at recorded activity levels over a range of dates. This enables physical review of patient functional status. Additional physiologic data can be recorded along with the activity data, and this too may be reported out from the implanted device to a medical communications system for alarm purposes, filtrating drugs or other monitoring tasks.

Abstract: A flow formed encapsulated integrated circuit package (100) includes a printed circuit substrate (160) having upper and lower opposed surfaces and one or more anchor holes (150). The one or more anchor holes (150) have an upper aperture in the upper surface and a lower aperture in the lower surface. One or more integrated circuit die (130) are electrically and mechanically attached to the upper surface of the substrate (160). In addition, a solder resist mask (190) is attached to the lower surface of the substrate which covers the aperture of the one or more anchor holes (150). Flow formed material (110) is formed around the integrated circuit die (130) so as to encapsulate the one or more integrated circuits (150), the flow formed material (110) covering at a least a portion of the upper surface of the printed circuit substrate (160) and extending substantially into the anchor hole (150).

Abstract: A second level of vehicular repeater units is added to a conventional repeater system. The secondary vehicular repeaters may be specialized units, such as, motorcycle units that may be rendered inoperative due to battery drainage. The present invention provides that no secondary vehicular repeater shall transmit if a primary vehicular repeater is in the area. Only if there are no primary vehicular repeaters in an area will a secondary vehicular repeater transmit, and then, the present invention provides a prioritization arrangement so that no one secondary vehicular repeater is overly burdened by constant operation.
