Publication number: 20090185918Abstract: A liquid ring pump includes an external housing enclosing a volume including a lower fluid reservoir. A rotatable inner housing is within the volume of the external housing, the inner housing enclosing an inner fluid chamber. A pitot tube provides fluid communication between the lower fluid reservoir and the inner fluid chamber. The housings and pitot tube are adapted so that when the inner housing rotates, fluid flows from the lower fluid reservoir through the pitot tube into the inner fluid chamber to develop a liquid ring within the inner fluid chamber such that an inner radial wall of the liquid ring is just radially outward from a point where the pitot tube enters the inner fluid chamber.Type: ApplicationFiled: January 23, 2009Publication date: July 23, 2009Applicant: DEKA Products Limited PartnershipInventors: Jason A. Demers, Scott A. Leonard, Kingston Owens

Publication number: 20080175719Abstract: Embodiments of the present invention relate generally to certain types of reciprocating positive-displacement pumps (which may be referred to hereinafter as “pods,” “pump pods,” or “pod pumps”) used to pump fluids, such as a biological fluid (e.g., blood or peritoneal fluid), a therapeutic fluid (e.g., a medication solution), or a surfactant fluid. The pumps may be configured specifically to impart low shear forces and low turbulence on the fluid as the fluid is pumped from an inlet to an outlet. Such pumps may be particularly useful in pumping fluids that may be damaged by such shear forces (e.g., blood, and particularly heated blood, which is prone to hemolysis) or turbulence (e.g., surfactants or other fluids that may foam or otherwise be damaged or become unstable in the presence of turbulence).Type: ApplicationFiled: April 13, 2007Publication date: July 24, 2008Applicant: DEKA Products Limited PartnershipInventors: Brian Tracey, Larry B.

Patent number: 6944769Abstract: An apparatus and a method in a data processing system are provided for insuring the security of data accessed from removable media. Normal virus scanning occurs after data is loaded into the main memory, but infection by a virus may have already occurred by this time. Therefore, it would be beneficial to check for possible virus infection before the data is transferred to main memory. A security key is read from the removable media. As encrypted data is read from the device, it is decrypted using the security key and then re-encrypted using the same security key to produce new data. The original data is accepted and sent to main memory if it is identical to the new data produced by decryption and re-encryption. If the two sets of data are not identical, then the data transmission from the device is aborted and all data on the removable media is rejected. The decryption/re-encryption checking is performed in hardware and so it can occur in real time.Type: GrantFiled: August 10, 2000Date of Patent: September 13, 2005Assignee: International Business Machines CorporationInventors: Scott Leonard Daniels, Danny Marvin Neal, Yat Hung Ng

Patent number: 6934852Abstract: A method and system for protecting electronic files from unauthorized access. The drive on which the file is stored is provided with a hardware identification code, which is unique to the drive. An Operating System (OS) extension allows a user to provide a security code required to access a requested drive. OS device driver, working in conjunction with the extension of the OS checks the requested drive to determine if an access code is required, and the drive responds with the security code or a default code. The default code indicates that the drive is globally accessible to users on the system. When a security code is returned, the OS compares the security code to the access code provided and provides the user with access to the drive only when the access code matches the security code.Type: GrantFiled: December 11, 2000Date of Patent: August 23, 2005Assignee: International Business Machines CorporationInventors: Scott Leonard Daniels, Danny Marvin Neal, Yat Hung Ng

Publication number: 20050112007Abstract: Embodiments of the present invention are directed toward systems and methods of transferring fluid using devices that have a rotatable housing. One embodiment of the invention attaches a fluid-drive element to a rotatable housing to drive fluid into a conduit for transfer. In another embodiment, a pitot tube is attached to the rotatable housing, the motion of the housing driving fluid into the conduit for transfer. Other embodiments of the invention may utilize a pressure difference to drive fluid through a conduit. Embodiments of the invention may also utilize baffles to alter circulation of fluid that may be induced by the motion of the rotating housing, to promote fluid transfer through a conduit. Some of the aforementioned embodiments may be especially useful in transporting fluid in a liquid ring pump with a rotatable housing.Type: ApplicationFiled: November 24, 2003Publication date: May 26, 2005Applicant: DEKA Products Limited PartnershipInventors: Jason Demers, Scott Leonard, Kingston Owens
