Abstract: An integrated circuit (IC) chip with a self-contained fluid sensor and method of making the chip. The sensor is in a conduit formed between a semiconductor substrate and a non-conductive cap with fluid entry and exit points through the cap. The conduit may be entirely in the cap, in the substrate or in both. The conduit includes encased temperature sensors at both ends and a central encased heater. The temperature sensors may each include multiple encased diodes and the heater may include multiple encased resistors.

Abstract: An apparatus for microwave heating is disclosed, comprising a heating appliance capable of providing thermal heat to material within the appliance. A pedestal within a middle portion of the heating appliance is capable of providing further thermal heat to the material, which may comprise food or liquid, or other microwavable material.

Abstract: A strip of dental articulating paper is held pincer-like between two biased lateral edges of an outer housing. A grip head overlying a liner protects one lateral edge of the dental articulating paper, with a linear tracing of petroleum jelly formed on the liner adjacent exposed surfaces on both sides of the dental articulating paper. During storage, the grip head is received by and between the two biased lateral edges of the housing. Immediately prior to use, the dental professional slowly removes the grip head from the housing, with the biased lateral edges pressing against the sides of the withdrawing articulating paper, spreading an even, thin film of petroleum jelly over the surfaces thereof.

Abstract: Apparatus for controlling primary air flow and pulverized coal flow to a plurality of burners in a coal-fired boiler includes a plurality of coal dampers arranged to supply a mixture of air and pulverized coal to respective burners in the coal-fired boiler, each damper having a damper body and at least two orifice plates pivotally secured therein, the orifice plates movable between open and closed positions; a real time coal flow monitoring device operatively associated with each damper that is adapted to generate analog signals representing real time coal flow through its respective damper; and a programmable logic controller adapted to receive the analog signals and to adjust the orifice plates to balance the flow of air and pulverized coal to each of the plurality of burners.
