A system for monitoring and modifying the quality and temperature of air within a conditioned space includes a blower unit, a damper unit for selectively admitting outside air into the conditioned space, a temperature moderating unit and a control unit. The control unit includes a thermostat and conventional temperature control apparatus for selectively activating the temperature moderating unit to maintain the desired temperature in the conditioned space. The control unit also incorporates CO2 concentration measuring and control apparatus which includes a small CO2 sensor. The CO2 sensor includes a cathode, an anode and a solid electrolyte disposed intermediate and electrically in contact with each of the cathode and the anode to effect a primary electrical cell. A heater and a heater thermostat serve to maintain the temperature of the cell at about 250° C. The cathode and anode materials and the chemical composition of the electrolyte are further selected such that the voltage generated across the heated cell varies in accordance with the CO2 concentration. CO2 concentration modifying apparatus is responsive to sensing a first predetermined CO2 concentration for turning on the blower unit and to sensing a second, higher, predetermined CO2 concentration for actuating the damper unit to admit outside air.

A general joint component framework that is capable of exhibiting complex behaviors of joints in articulated figures is provided. A network of joint components is used to model the kinematics of a joint. A joint builder can specify parameters for each of the joint components and join the joint components to form a joint set function that captures the biomechanical dependencies between the components. The joint function has fewer inputs than the total number of possible articulations yielding both simple control and biomechanically accurate joint movement.

An electrical receptacle assembly with protective housing is adapted for installation in unconventional areas or surfaces, including areas that are more susceptible to spills or other contaminants than traditional mounting locations. The electrical receptacle assembly includes a receptacle subassembly with a main receptacle body and a front surface portion in which a plurality of electrical contacts are housed and made accessible to corresponding contacts of an electrical or electronic device. A housing defines a cavity for receiving the receptacle body, and a face plate is coupled to the housing and defines a receptacle opening for engaging and supporting the electrical receptacle subassembly. The face plate may take on many different sizes and shapes for a desired application, while the other components of the electrical receptacle assembly can remain the same.

A closed-circuit heliox delivery system and methods for alleviating symptoms of COPD and related disorders are provided. The system is self-monitoring and can be used outside of a hospital environment. The system contains a gas supply fluidly connected to a breathing circuit. The breathing circuit contains an upper airway device, such as a mask. The system contains a sensor(s) and controller. The sensors measure parameters in the system, the ambient environment, or related to the physiological state of the user. The controller can adjust the system to maintain parameters within the device, i.e. pressure, temperature, humidity, within predetermined ranges. The controller can adjust the system to maintain a target physiological state of the user, i.e. target blood oxygen levels or Work of Breathing (WOB).

A shock strut for an aircraft landing gear having a retract actuator that is moveable in length to deploy or retract the landing gear, that includes a shrink strut and a transfer device. The shrink strut may be compressed in length for stowage in the fuselage. The transfer device may be in closed fluid communication with the strut shrink for transferring and receiving hydraulic fluid to and from the strut shrink. When actuated by an aircraft hydraulic or electric system independent of any motion of the retract actuator, the transfer device may drive hydraulic fluid to the strut shrink thereby compressing or shrinking the shrink strut to a partially compressed length.

The present invention provides an optics assembly, a reflectometer, and a diagnostic device for providing quantitative measurement of optical radiation reflected from a sampling area on an assay matrix. The reflectometer includes an optical radiation source and a detector. The optical radiation source and the detector are mounted in a single plane. An optics assembly is configured to direct the illumination from the optical radiation source to the sampling area on the assay matrix and to direct the radiation diffusely reflected from the sampling area to the detector. The optics assembly is positioned over the face of the circuit board having the optical radiation source and detector mounted directly thereto. The present invention also provides a method for determining the presence of one or more selected analytes in a sample employing a plurality of sampling areas on one or more assay matrixes.

Proposed is a pyrolysis reactor for processing solid municipal and domestic wastes by means of a pyrolytic reaction in the pyrolysis chamber without access of oxygen to the reaction system. The reactor is characterized by containing two waste-feeding screws which have tapered shapes, a gap between the outer surfaces of the threads, are inclined in the vertical plane and converge towards each other in a horizontal plane in the direction from the inlet to the outlet end. The gap is adjustable with diminishing toward the outlet end.

An optical-fiber based light channel system is included in an ion / electron beam tool for imaging and / or processing integrated circuits. The optical channel system includes an image collection portion, an optical fiber image transmission portion and a detector portion. The image collection portion includes micro-optical components and has submillimeter dimensions, so that it is easily accommodated within the working distance of the ion / electron beam tool. The entire system is sufficiently compact and lightweight so that it may easily be mounted on a translation stage inside the sample chamber, which permits the optical channel to be mechanically extended and retracted to avoid blocking the primary ion or electron beam. The system may be mounted to a translation stage or to a gas injector assembly, which may itself be mounted to a flange plate on the chamber wall with feed-through ports for electrical and optical signals.
