Abstract: A method for manipulating a graphic widget in a three-dimensional environment displayed on a touch panel of an interactive input system is provided. The method includes tracking the x-y positions of two touch points associated with the graphic widget; and modifying the z-position of the graphic widget in accordance with changes in the distance between the x-y positions of the touch points. An interactive input system and computer readable medium embodying the method is also provided.

Abstract: A control module for selectively switching electrical power from a circuit breaker with the circuit breaker including a load lug coupled to a load wire and mounted in a panelboard. The control module includes a housing in-line with and directly attached to the circuit breaker inside the panelboard and a pair of contacts coupled to an actuator mounted in the housing. One contact is coupled to the load lug and one contact is coupled to the load wire. The actuator is operated from a location remote from the control module and the contacts operate independently from the circuit breaker.

Abstract: An air handling blower for HVAC equipment includes a blower housing adapted to accommodate centrifugal impellers of selected inside and outside diameters of the impeller blades wherein the inside diameter of the largest diameter impeller accommodated by the housing is not less than the outside diameter of the smallest diameter impeller accommodated by the housing without loss of performance. The blower housing preferably has a continuously increasing cross-sectional airflow area for air being discharged from the blower and extending from a cutoff edge to an outlet.

Abstract: Heat exchange apparatus includes elliptical cross section heat exchange tubing provided with a partition dividing the interior of the tubing into at least two parallel flow passages. The flow passages are delimited by inwardly projecting fins formed on the tubing wall and on the partition, the fins extending parallel to each other and having a height less than the anticipated thickness of the velocity boundary layer of heat exchange fluid flowing through the tubing passages. The tubing may be arranged in serpentine or coiled arrangements of the heat exchange apparatus or parallel tubes extending between heat exchanger header tanks. The heat exchange apparatus is particularly adapted for use in HVAC systems.

Abstract: Famciclovir monohydrate and its pharmaceutical use.

Abstract: A centrifugal blower for a furnace, heat pump, or other type of air handling unit includes a heat-generating blower housing that heats the airflow as the air passes through the blower housing. In some cases, the housing is made of a thermosetting resin impregnated with graphite or co-molded with a graphite cloth. Heat is generated within the housing wall by applying voltage across the housing.

Abstract: The present invention relates to connector tools for seating connectors on a substrate such as a printed circuit board. In various embodiments, the connector tools can be made by wire electrode discharge machining (WEDM) process. In the embodiments, the connector tool includes reinforced ribbed end walls, ribbed internal walls, interconnected walls and contours that reduce tool and connector damage. In other embodiments, the connector tools include guiding structures that align the connector tool to the connector before seating the connector so that the connector tool aligns to the connector pins and body to avoid damage to the connector and/or the substrate. In another embodiment, the connector tool has guiding skirts and surfaces to capture the connector in position then seat the connector. Thus, the invention reduces connector and substrate damage during manufacturing, reduces tool damage, and lowers product costs by boosting manufacturing yields.
