Patent CA-2222340-A1 (CA)
Title: Radiographic/fluoroscopic imaging system with reduced patient dose and faster transitions between radiographic and fluoroscopic modes
Inventor: TAYLOR JAMES
IPC: A61B6/02
Filed: 1997-11-26
Abstract: A radiographic/fluoroscopic imagining system provides rapid transition from fluoroscopic to radiographic imaging mode by maintaining the X-ray tube high voltage, increasing the filament current, allowing X-ray tube current to increase toward the desired radiographic current, and terminating exposure when the desired X-ray dose has been achieved.  Rapid transition from radiographic to fluoroscopic imaging mode is provided by reducing x-ray tube high voltage to produce an equivalent fluoroscopic-level x-ray output at high initial current, dropping filament current, and enabling ABS control of the high-voltage.  As x-ray tube current drops, ABS correspondingly increase high voltage to maintain the desired output.  The imaging system obtains movement-related information by analyzing a video signal (such as from fluoroscopic image or an image from an optical camera trained on the patient), or from operator movement requests. The imaging system uses movement-related information to responsively control fluoroscopic pulse rate or other imaging parameters.  The imaging system can also use such information to initiate a radiographic exposure, or advance to thenext step of an operator programmed examination consisting of interspersed fluoroscopic and radiographic exposures.  This results in a lower dose to both the patient and the examiner, consistent with high image quality.

Title: Over-fire air control system for a pulverized solid fuel furnace
Inventor: GARCIA-MALLOL JUAN A
IPC: F23C7/00
Filed: 1998-05-27
Abstract: An over-fire air control system for a pulverized fuel furnace, in which a burner assembly is provided for discharging a fuel/primary air mixture along with secondary air to combust the fuel. The amount of primary air and secondary air discharge is controlled to achieve incomplete combustion, and an overfire air port is provided through which additional air is discharged to complete the combustion. The overfire air port receives two streams of air, one high in volume and low in velocity and the other low in volume and high in velocity. Dampers are provided for controlling the air streams to achieve optimum quantities and velocities of the air. According to one embodiment, a source of one of the air streams is the primary air portion of the fuel/primary air mixture applied to the burner assembly. As a result, the formation of nitrous  oxides are reduced and fairly precise air fuel ratios can be maintained despite variations in the quality of the fuel and the pressure and amount of primary air.

Title: A control architecture for a homogeneous routing structure
Inventor: TRESTED WARREN CLIFTON JR
IPC: H04L12/56
Filed: 1998-09-23
Abstract: A system for providing segmented control of a single, homogeneous routing structure, such as a switch fabric, includes application control elements that are each responsive to embedded signal status information for each of the input signals to the switch fabric. Within each of the application control elements, a configurable arrangement of selectors and control logic is used to provide domain segmented control of each of the separate switching functions for a particular application. Each application control element performs an application specific address resolution function to resolve a single address of one of the input signals based on the embedded signal status of each of the input signals. This single address is provided to the switch fabric so that the corresponding input signal can be selected at the switch fabric output. Because embedded signal status is provided locally at each selection point within the application control element, the control functions for each of the separate switching functions are decoupled, and, as a result, each of the separate switching functions can be independently controlled as a separate domain within the application control element. The single, homogeneous switch fabric simultaneously supports multiple applications in parallel because each of the application control elements is used to control a separate output from the switch fabric. Because of the one for one association between application control elements and switch fabric outputs, the switch fabric is effectively "channelized" whereby each channel of the switch fabric supports a separate application.

Patent CA-2252231-A1 (CA)
Inventor: GREWE TIMOTHY MICHAEL
IPC: B60L50/15
Filed: 1998-10-29
Abstract: A hybrid electric vehicle includes a lead-acid traction battery made up of a plurality of series-connected modules. During operation of the vehicle, the traction battery is discharged for acceleration, and charged by an ancillary power source. The traction battery is desirably not fully charged at the beginning of a day's operation, so that overcharging cannot occur, so the battery spends long periods of time in a partially charged condition. When not fully charged for long periods of time, sulfation may reduce the charge storage capacity of the battery. A maintenance procedure takes place when the vehicle is not operating, in which one or more modules of the traction battery, but less than all the modules, are fully charged, then partially discharged. The full charging tends to reduce sulfation in the particular module being maintained, and the partial discharge restores its charge condition to that prior to the full charge. Each of the modules is eventually maintained by a programmed controller. The charging energy comes from an auxiliary battery, and the discharge energy is returned to the auxiliary battery, so there is little net loss of energy. If the maintenance procedure is interrupted before full charge of a module, that module is scheduled for the next maintenance. If the maintenance is interrupted before partial discharge, the partial discharge is accomplished by equalizing the voltage of the battery modules.

IPC: A61B19/00
Filed: 1997-05-07
Abstract: An integrated optical biopsy forceps device and a method for tissue identification by optical analysis and biopsy sampling at a site within the body. The device includes an elongated catheter body for introduction into the body and navigation to an area of interest. An optical fiber extends through the device, from the proximal end, where it may be connected to electro-optical spectral analysis equipment, to a distal tip for illuminating and receiving light energy from tissue at the location of the tip. The distal end of the device has a pair of cutting jaws pivotally mounted at the distal end of the catheter body and controlled by control wires extending through the catheter body to a control handle at the proximal end, or by the optical fiber. The device may be spectroscopically guided to a site of interest within the body. The fiber tip is positioned coaxially with the jaws at the zone of contact and cutting of the jaws, and is retracted as the jaws close, so that the biopsy sample is taken exactly at the spot being viewed by the optical fiber.
