International Classification:

A61B 19/00

US Classification:

606130

Abstract:

A highly articulated robotic probe comprises an outer sleeve and an inner core. The outer sleeve and inner core include a plurality of links. The links of the outer sleeve and inner core are configured to pivot relative to one another. Various characteristics of the links determine the overall pivot angle of the articulated probe. Each of the plurality of links may have one or more channels. The channels form a semi-continuous passage from link to link and are configured to receive an elongated member such as an inner core, tool or cable. One or more cables may be used to control the outer links of the outer sleeve and the inner links of the inner core. Various characteristics of the cables determine the overall performance of the articulated probe.

International Classification:

A61B 19/00

US Classification:

606130

Abstract:

In an introduction assembly for an articulated probe, a feeding mechanism has actuators for controlling the articulated probe. The introduction device is fixed in a positional relationship to the feeding mechanism. The introduction device includes a support member configured to support an articulated probe. A proximal end of the support member has an entrance configured to guide the articulated probe into contact with the support member. A distal end of the support member has an exit configured to guide the articulated probe from the support member into a region of interest.

International Classification:

F02D 102
F02M 4500

US Classification:

123449

Abstract:

A fuel injection pump of the rotary distributor type having opposed fuel pumping pistons housed within a rotor and actuated by an internal ring cam. Fuel distribution, metering and timing control are effected through ports and slots associated with the rotor, the pump housing and a spill sleeve. The angular position of the cam is varied automatically in accordance with changes in engine speed as are the relative positions of certain ones of said ports and slots to provide an automatic advance of the fuel injection timing. The pump is particularly suited for electronic governing, electronic timing control and electronic control of rate of injection.

Assignee:

Intermedics Infusaid, Inc. - Norwood MA

International Classification:

A61M 514

US Classification:

604 67

Abstract:

A positive pressure positive displacement implantable infusion pump. A positive pressure fluid reservoir maintains infusate for delivery by a positive pressure displacement pump. Infusate is drawn by the pump into a drug pressurant chamber. A check valve prevents backflow into the reservoir. The check valve may independently establish a basal flow rate by not completely sealing in the forward flow direction. The pump pulses to expel and fill the chamber thereby establishing the flow rate, basal or bolus through a restrictor interposed between the chamber and the infusion site. The pump may run in open loop, pre-programmed or externally programmed modes of operation.

International Classification:

F02M 5100

US Classification:

123478

Abstract:

The method and apparatus for generating start of combustion signals associated with the combustion events in a diesel engine, and for using such signals to control the timing of fuel delivery to the engine. The combustion event is sensed, as by an electrostatic or optical sensor, and signal conditioning circuitry provides a start-of-combustion signal which is directly and precisely indicative of the time of the onset of combustion. The sensors include self-cleaning capabilities for extended operating life on an engine. The sensors may be incorporated in the structure of a glow plug. The SOC signal is advantageously supplied to a timing control circuit which delivers a timing control signal to a fuel delivery device, such as the controller associated with a fuel pump. The control circuit stores one or more start of combustion values which indicate the desired timing, relative to an engine cycle, for the start of the combustion event as a function of speed and load. One or more adjustment signals are stored and applied as a function of speed and load to adjust the desired signal such that the control signal is corrected for delays.

Assignee:

AMBAC Industries, Incorporated - Springfield MA

International Classification:

F02D 102
F02M 4500

US Classification:

123502

Abstract:

An improved timing control mechanism is provided for an engine-driven fuel injection pump of the type having plungers actuated by an adjustable cam. The cam is adjusted by the linear displacement of a timing piston operating in a cylinder. A pressurized hydraulic fluid admitted to a pressure chamber at one end of the cylinder provides a force against one end of the timing piston which is opposed by a biasing element, such as a spring. A rotary servo valve extends into an axial bore in one end of the timing piston for controlling the flow of hydraulic fluid through a control orifice formed in the wall of the piston bore and connecting with the cylinder's pressure chamber. The servo valve is axially fixed and includes an inclined, typically helical, control edge. Upon rotation of the valve, as by an electric rotary stepper motor, the control edge effectively moves "axially" relative to the control orifice to vary flow therethrough and thus cause the piston to track that "axial" positioning of the control edge. The valve's control edge is so positioned relative to its flow-occluding surface as to compensate for destabilizing forces transmitted to the timing piston through the cam.

US Classification:

123501

Abstract:

The method and apparatus for generating start of combustion signals associated with the combustion events in a diesel engine (10), and for using such signals to control the timing of fuel delivery to the engine. The combustion event is sensed, as by an electrostatic (230, 330) or optical (130, 430) sensor, and signal conditioning circuitry (32) provides a start-of-combustion (SOC) signal (34) which is directly and precisely indicative of the time of the onset of combustion. The sensors (130, 230) include self-cleaning capabilities (48, 248) for extended operating life on an engine. The sensors may be incorporated in the structure of a glow plug (330, 430). The SOC signal (34) is advantageously supplied to a timing control circuit (26) which delivers a timing control signal (28) to a fuel delivery device, such as the controller (16') associated with a fuel pump (16). The control circuit (26) stores (65) one or more start of combustion values (SOC*) which indicate the desired timing, relative to an engine cycle (24), for the start of the combustion event as a function of speed (25) and load (27). One or more adjustment signals (. DELTA.
