Title: Constant rate fluid delivery device with selectable flow rate and titratable bolus button
Inventor: POWELL KENNETH
IPC: A61K9/22
Filed: 2001-08-17
Abstract: A wearable, self-contained drug infusion device is disclosed that is capable of achieving the precise flow rate control needed for dose-critical drugs such as insulin. In preferred embodiments of the device, at least two flow channels (76, 78) are utilized in conjunction with a series of valves (82) for providing a user with selectable, constant flow rate control.  The device can be made with small dimensions so that it can be worn by the user with a minimum of discomfort and inconvenience. In addition, the simple mechanical nature of the device provides the user with close control over the flow rate, which is required for safe and effective delivery of insulin and other drugs. Also, the absence of electronic components allows the device to be manufactured inexpensively. The device is pro provided with a first channel (76) that is long and narrow, functioning as a flow restrictor. The first channel (76) is preferably provided in a serpentine pattern. A second channel (78) is also provided that has a larger cross section so that flow is not re restricted. A series of valves (82) are used to force the flow of fluid through a selectable portion of the serpentine portion of the first channel (76) before entering the remainder of the sec second channel (78) and flowing to the delivery cannula (48). In one embodiment of the device, a needle port is provided in fluid communication with the delivery cannula for delivering bolus injections. In another embodiment, a bolus button (100) is pro provided for delivering bolus injections. A flow restrictor (102) is preferably included in the bolus button to limit the rate at which the bolus button refills.

Title: Systems and methods for determining the n-best strings
Inventor: RILEY MICHAEL DENNIS
IPC: G10L21/00
Filed: 2003-03-21
Abstract: Systems and methods for identifying the N-best strings of a weighted automaton. A potential for each state of an input automaton to a set of destination states of the input automaton is first determined. Then, the N-best paths are found in the result of an on-the-fly determinization of the input automaton. Only the portion of the input automaton needed to identify the N-best paths is determinized. As the input automaton is determinized, a potential for each new state of the partially determinized automaton is determined and is used in identifying the N-best paths of the determinized automaton, which correspond exactly to the N-best strings of the input automaton.

Abstract: A trailer for transporting live poultry hatchlings has a cargo space for containing a plurality of perforated hatchling containers. The hatchling containers are stacked to create a central passage for air flow along the length of the trailer from which the air is admitted into a side duct on each side of the trailer through apertures in each side wall of the cargo space. This creates a transverse flow of air through the hatchling container s. A variety of measures may be undertaken alone or in combination to promote a similar transverse flow of air at all positions along the length of the trailer. The size of the apertures, spacing between apertures, cross-sectional area of the side ducts, cross-sectional area of the cargo space, or a combination thereof, may be varied along the length of the trailer to promote a similar transverse flow of air at all positions along the length o f the trailer. The air collected within the side ducts may be exhausted and/or at least a porti on thereof may be recycled in order to maintain life sustaining environmental conditions within the trailer.
