Title: Method and apparatus for fluid flow control
Inventor: GEORGE FRED
IPC: F24F11/75
Filed: 2004-01-16
Granted: 2011-09-06
Abstract: Methods and apparatus are provided for modulating a flow of fluid in a duct using a rotating member that rotates in the duct. A sensing unit senses the rotation speed of the rotating member and generates a rotation signal as a function of the sensed rotation speed. A control unit receives the rotation signal from the sensing unit and generates a control signal to modify the rotation speed of the rotating member. The apparatus can be self-powering by generating an electric current in response to rotation of the blade.

Abstract: Portable computers of the type commonly referred to as "laptop" computers and "notebook" computers are becoming very popular. They typically include a housing with a lid which is movable between open and closed positions, a display which is mounted on the lid, and a keyboard which is mounted on the housing beneath the lid, the keyboard and display being exposed when the lid is in the open position and being hidden and protected when the lid is in the closed position. These systems also include a battery which serves as a source of power. If a user inadvertently closes the lid without remembering to turn off the power, the system can continue to operate and will run down the battery. A portable computer system includes housing, a lid supported on the housing for movement between open and closed positions, a keyboard supported on the housing below the lid, and a display provided on the lid. When the lid is opened, the keyboard is accessible and the display is visible, whereas when the lid is closed the keyboard and display are hidden and protected. The computer system includes a processor disposed within the housing and having a first operational mode in which it executes instructions and a second operational mode in which it is in a reduced power suspend state from which it can automatically exit in response to a predetermined condition. The system includes an arrangement responsive to closing of the lid when the processor is in its first operational state for switching the processor to its second operational state.

Patent CA-2559469-C (CA)
Inventor: MACAULAY IAIN C
IPC: E21B17/10
Filed: 2006-09-12
Granted: 2009-11-10
Abstract: Methods and apparatus for making a connection that can be rotationally locked by expansion are disclosed. Threaded tubular ends include a slot cut across a thread at a location along the circumference of the thread. Threading two tubular members that have the slot disposed in either or both of a pin or box end of the tubular members establishes the connection. The slots represent no impediment to the make-up or break-out of a box by pin connection prior to expansion. During expansion of the connection, the threads of either the box or pin end are forced via plastic flow into the slot in the corresponding thread. This results in locking the connection and preventing relative rotation between the two tubular members, which could otherwise loosen the connection.
