Abstract: An HVAC system is provided in which data is obtained and reports generated. Actions can be taken with respect to the HVAC unit on the basis of the reports generated.

Abstract: The invention provides chimeric cannulae polypeptides and methods for making and using them. In one aspect, the invention provides compositions and methods for the identification, separation or synthesis of proteins or ligands. In one aspect, the invention provides compositions and methods for making and using nanotubules. In one aspect, the invention provides compositions and methods for the selection and purification of chiral compositions from racemic mixtures. The invention provides compositions comprising polymers prepared by self-assembly of a plurality of monomeric polypeptide units, including nanorobots, biochips, drug delivery systems. In one aspect, the polymer can form a nanotube, and the polymer (nanotubule) can encapsulate a drug molecule—a drug delivery systems of the invention. A drug delivery system of the invention may be delivered to a particular location of human body to effectively cure a disease or treat a symptom.

Abstract: A refuse collecting device which removably secures a disposable handle-equipped sack includes a scoop of rectangular box-like configuration having front and rear openings, and structure for engaging the handles of the sack. An elongated manipulating staff is pivotably secured to the scoop in a manner such that, when the device is lifted, the scoop automatically swings by gravity effect, causing the front opening to become upwardly directed.

Abstract: An air spring apparatus for a vehicle suspension. An active air cylinder and piston of the apparatus are connected in series with the vehicle suspension. An inactive air cylinder constituting an air column extension of the active air cylinder is connected in series with the active air cylinder by an air conduit. The spring rate of the system is automatically adjustable to produce optimum isolation of impulsive forces and to maintain the forces on the road under dynamic conditions essentially equal to those forces under static conditions.
