Abstract: A multi-zone monitoring system allowing simultaneous measurement of separate zones of multi-zone wellbore formations comprising a multi-component umbilical containing both electrical lines and a hydraulic fluid lines, an inflatable isolation packer that can traverse through the wellbore and be inflated with hydraulic fluid to seal off a portion of the wellbore wherein the inflatable isolation packer is connected to a hydraulic line of the multi-component umbilical, wherein the inflatable isolation packer further comprises: one or more cable bypass feed throughs for the umbilical's electric and hydraulic fluid lines, wherein the hydraulic line is attached to the inflatable isolation packer with compression fittings.

Abstract: A dual entry safety cuff port for use in a correctional facility. The dual entry safety cuff port includes a frame and a panel, the panel configured to slide within the frame between a fully open position and a closed position. The dual entry safety cuff port also includes a lock. The lock configured to allow operation of the dual entry safety cuff port from either side of the panel. The dual entry safety cuff porter further includes a flange on the panel, the flange configured to stop the panel in the fully open position.

Abstract: A method to determine a performance characteristic of an exhaust system of an engine, where the exhaust system includes an exhaust gas sensor that outputs an exhaust gas signal. A combustion event in a cylinder is fueled at an air-fuel ratio selected to produce exhaust gas that is expected to be distinguishable by the exhaust gas sensor from exhaust gas produced by other combustion events, and used to determine the performance characteristic. The performance characteristic may be an exhaust gas transport time of the exhaust system, a sensitivity characteristic of the exhaust gas sensor, or a fueling correction value necessary to restore fueling to, for example, stoichiometry. Such a method is useful to detect physical changes in the exhaust system such as relocating the exhaust gas sensor, or detect if the exhaust gas sensor is damaged or not operating properly.

Abstract: An adjustable hydraulic valve lifter has a lifter body and an internal cylindrical body. The lifter body has a first longitudinally cylindrical internal bore and a first substantially closed lower end, and the internal cylindrical body is axially slideable and rotatable within the first longitudinally internal bore, forming a first oil chamber. A first spring is positioned to bias the internal cylindrical body away from the lifter body. A first oil flow path permits the flow of oil into the first oil chamber through a first check valve. An oil outlet in the lifter body adjacent the first substantially closed lower end allows oil to escape from the first oil chamber as controlled by an oil control recess in an outer surface of the internal cylindrical body.
