Abstract: Devices used to pressurize, depressurize, or otherwise displace fluid are disclosed. The devices may be configured to displace fluid in order to inflate or deflate a medical device, such as a balloon. The devices further include features and mechanisms for limiting pressure generation so as to avoid damage due to overpressurization.

Abstract: Techniques are described for managing data transfer between an enterprise system and a third-party provider system, through a batch interface of the third-party provider system. A batch of transaction data is uploaded through the batch interface for enrichment, and enrichment data is received in response. The enrichment data provides additional context regarding each of the transactions specified in the uploaded batch. The enrichment data can be sent back to the presented to user(s) through various tools. Prior to uploading, the batch can be filtered to include those records corresponding to users who have opted into a service. Filtering can also exclude records for which enrichment data has already been provided through a real-time process. Reconciliation can be performed to ensure integrity of the communicated data.

Abstract: An apparatus (100) is provided for dispersing heat from an integrated circuit (202) to a heat sink (404). The apparatus (100) is formed on a nonconductive body (102) having at least two conductive surfaces (110, 112) disposed thereon. One of the conductive surfaces (110) is reflowed to a heat generating lead of the integrated circuit (202), and the other conductive surface (112) provides a surface for contacting a heat sink (404). The apparatus (100) and integrated circuit provide a package (200) which can be tape and reeled (300) for easy mounting to a printed circuit board (402) of a communication device (400).

Abstract: An apparatus (100) for installation and removal of a mobile communication device (102) to and from a bracket (104), such as mounted in a vehicle, is provided. The apparatus (100) includes a handle (120) pivotably coupled (160) to the mobile communication device (102), the handle having first and second lever arms (122, 124). The apparatus (100) further includes a bracket (104) having first and second pivot point pins (130, 132) and a compliant member (144). During installation the handle (120) is pivoted in a first direction such that the first and second lever arms (122, 124) engage the first and second pivot point pins (130, 132), and the handle compresses the mobile communication device (102) into the compliant member (144) for retention. The lever arms (122, 124) disengage the pivot point pins (130, 132) as the handle (120) is pivoted in an opposite direction thereby releasing the mobile communication device (102) from the bracket (104).

Abstract: A centralizer system is provided for use in a marine riser system with an insulated pipe, which may be a titanium stress joint. The centralizer system utilizes one or more centralizers mounted such that insulation material is provided in an annulus between the one or more centralizers and the stress joint. A clamp is utilized to axially affix either one centralizer or multiple centralizers to the stress joint. The clamp is comprised of a plurality of sections with cylindrical interior surfaces which are tightened together using fasteners. The cylindrical interior surfaces avoid damage to the insulation layer which may be elastomeric. The clamp and each centralizer have radially directed projections thereon which interlock the clamp with each centralizer. Because the clamp is axially affixed, the centralizer is then also axially affixed. In one embodiment, the centralizer is axially moveable to a desired axial position prior to being interlocked to the tightened clamp.

Abstract: A centralizer system is provided for use in a marine riser system to provide a stress joint or keel joint with a upset portion. The centralizer is preferably heat-shrink fitted to the upset portion of the keel joint. The upset portion has tapered sections on the upper and lower ends which may be of various shapes and lengths that gradually blend into the outer diameter of the pipe used as the keel joint. The centralizer may also be heat-shrink fitted to one of the tapered sections. The centralizer may or may not utilize guide sections mounted on either end thereof. In a preferred embodiment, the centralizer comprises axially extending annular grooves in surrounding relationship to the upset portion, the grooves serving to permit forces acting on the centralizer to be redirected or dissipated to thereby prevent excessive buildup on a selected region of the upset portion adjacent the radial grooves.

Abstract: An active vibration isolation system (10) includes a plurality of stiff actuators, such as piezoelectric motors (12a-c; 284, 350) which support a small mass (18) inside of a case (300). A passive isolator (20) is interposed between the small mass (18) and the payload mass (M.sub.p). In the instance where the stiff actuators are piezoelectric motors, the sidewalls of the case (300) are used to provide compressive force along the variable length of each of the horizontal piezoelectric motor elements (284, 350) to prevent damage to same. Compensation circuitry (24) is connected between velocity sensors (17) and the stiff actuators to control the variable length thereof in this move-out-of-the-way system (10) and to compensate for resonating modes. Optionally, a payload mass velocity sensor (26) and associated circuitry may be used to provide additional control.
