Abstract: A system, method, and software for triggering regeneration of an adsorber connected with a flow of exhaust from an engine. An exhaust sulfur flow rate module estimates a sulfur accumulation rate associated with an adsorber as a function of a flow of fuel. A sulfur removal rate module estimates a sulfur removal rate associated with the adsorber. An accumulated sulfur loading module includes a counter the value of which is increased as a function of the sulfur accumulation rate and decreased as a function of the sulfur removal rate. A combustion manager module controls an engine to regenerate the adsorber once the counter reaches an upper threshold value.

A plurality of raised surface areas is located on an interior surface of the body. The raised surface areas extend into a hollow interior defined by the body a predetermined distance and are utilized to channel sound waves through the body and out the mouth.

Abstract: A compressor comprises an impeller (1) provided with a plurality of radial blades (4). The impeller (1) has an inducer diameter defined by the outer diameter of front edges (5) of the blades (4), and an outer diameter defined by the outer diameter of the blade tips (6). Each blade (4) is backswept relative to the direction of rotation of the impeller (1) with an angle of backsweep in the range 45° to 55°. The ratio of the impeller inducer diameter to the impeller outer diameter is in the range 0.59 to 0.63. The ratio of the compressor diffuser outlet diameter to the impeller outer diameter is between 1.4 and 1.55.

Abstract: A ball valve assembly comprises a housing with ball valve rotatably disposed in a valve chamber in the flow passage. The ball valve is rotatable between open and closed positions by a valve stem that is connected to the ball valve at one end. The ball valve has an open ended slot in which the end of the stem is received. During assembly the stem may be inserted into the housing first and then the ball valve introduced into the housing with the slot facing the stem and then moved in the direction of the slot so that that the stem is received in the slot. The arrangement enables the conventional bonnet in a ball valve assembly to be eliminated and therefore provides for a compact design.

Abstract: An improved ear tip for earphones and hearing protection is provided where comfort and occlusion of the ear are of most importance. The ear tip comprises an elastomer polymer resin material molded to form the material to the shape of the ear canal. A chamber is defined having a proximal and distal end, the distal end engages the acoustic exit of the transducer, sound source or sound attenuator and the proximal end of the bore is adapted to be disposed adjacent an eardrum. The inner body attaches to a nozzle, or audio playback orifice to naturally transition the acoustics from the transducer or sound attenuator to the eardrum via the ear canal. The ear tip can have a plurality of flexible annular flanges disposed at spaced intervals of the body with decreasing circumference as the flanges transition to the proximal end. Each flange tapers in a radius or curvilinear geometry as it progresses to the end of the object.

Abstract: A contact number encapsulation system is disclosed that is operable to consolidate a plurality of contact numbers associated with a given user into a single contact number. The system includes a call processing application that uses information contained in a SIP message header to determine a list of contact numbers to call. The SIP message header contains a call destination indication that is used by the call processing application to retrieve the list of contact numbers. The list of contact numbers is user defined and may be updated or modified by an account holder at any given time. Once the list of contact numbers is obtained, a simultaneous call module is used to simultaneously call each number contained in the list. As such, the account holder only needs to provide the primary contact number to individuals desiring to reach him/her instead of various numbers that are associated with various locations the account holder may be located.
