Title: Analytical method and apparatus
Inventor: VADGAMA PANKAJ MADGANLAL
IPC: G01N27/40
Filed: 1997-07-18
Abstract: Method and apparatus for detecting and/or determining ethanol in fluid samples using a substantially non-porous barrier (membrane) of un-plasticised polyvinyl chloride (PVC) interposed between the sample to be analysed and a detecting means responsive to ethanol. The ethanol diffuses through the barrier membrane and then is measured at the detecting means. The PVC membrane can be made by solvent casting, and is usually 10 to 40 .mu.m thick. Measurement can be by any known means, but preferably electrochemically (e.g. amperometrically). The PVC membrane may be part of a multiple membrane system. The method and sensor are useful for analysis of alcoholic liquors or beverages (for example beer, wines and other fermentation products), in their final form or at intermediate stages in their manufacture or storage, and also for the monitoring of a wide range of process, waste and effluent liquids.

Title: Method and system for configuring plug and play devices for a computer operating system
Inventor: LANDRY JOHN M
IPC: G06F9/445
Filed: 1999-06-29
Abstract: A method and system are disclosed for configuring PnP devices for a computer operating system by initiating a power on self test (POST) within a computer system for configuring PnP and PCI devices. During the process of configuring PnP and PCI devices, a list is composed of devices that are not absolutely necessary for booting the system (e.g. modem or ethernet controller). While the PCI devices are configured, if the system has no usable IRQ's, POST takes one from a nonessential PnP ISA (Industry Standard Architecture) device in the list, and gives it to the PCI device. The POST operation searches for the presence of a PnP operating system option while progressing through the startup sequence (of bootable media), and activates or deactivates all devices, depending on the type of media being attempted. If the medium is the hard disk (where the PnP operating system option resides), all of the PnP devices in the list are deactivated. If the medium is any other type (where a PnP operating system option is not likely to reside) the devices are activated.
