Abstract: ABSTRACT OF THE INVENTION         A method and apparatus for measuring blood glucose concentration by irraditing blood vessels with electromagnetic radiation using near-infrared radiation diffuse-reflection laser spectroscopy.       This invention uses electromagnetic radiation of  a  wavelength that is transmitted through the skin to the measurement part, for example, a blood vessel.    Since skin is mostly composed of water (H2O), which absorbs IR radiation in nearly the entire IR spectral range, only radiation of a certain, narrow protion of the IR spectral range called the "water transmission window" is transmitted through the skin.      The present invention uses electromagnetic radiation with a wavelength of 1.3µm?1.9µm radiation from a semiconductor diode laser. When electromagnetic radiation of these wavelengths irradiates the skin, light is transmitted through the skin to the blood vessel where the light interacts with the heterogeneous components of the blood.   The light which reaches the blood is then diffusely reflected by the blood.   The reflected light will have been modulated by the characteristic vibrations of the molecules which are major components of blood.    The reflected light is detected and provided as a digital signal to a one-chip microcomputer.   The one-chip microcomputer calculates a blood glucose concentration from the digital signal by reference to a calibration curve stored in the memory of the one-chip microcomputer.       The one-chip microcomputer causes the calculated blood glucose concentration to be displayed on a digital display.

Title: Infeed conveyor with multiple flight capability
Inventor: DOJAN HAROLD D
IPC: B65G19/26
Filed: 1991-04-30
Granted: 1995-08-01
Abstract: A product feed device includes multiple drivers mounted pivotally between a pair of parallel and opposed endless chains.          When pivoted to an active position, each driver engages a product and pushes the product along a path.  A set of cams is disposed upstream of the path.  Each of the cams is alternatively positionable in alignment between the chains, to engage successive drivers to either set or reset the drivers as they encounter the cam.  The cams set and reset successive drivers in different repeating sequences, thus to enable switching from one selected spacing between actuated cams to another, depending on which cam is in the operating position.  A pair of opposed guide members extend longitudinally along the path to confine the chains against transverse movement, and maintain each of the drivers in its selected orientation, whether set to active or reset to a bypass position.

Title: Method for guaranteeing data stored in a primary and secondary data base in a process control system
Inventor: BRISTOW ROBERT W
IPC: G06F15/16
Filed: 1991-09-18
Granted: 1997-11-18
Abstract: Data bases of a first and second input output processor (IOP), which are primary and secondary slave IOPs, respectively, are synchronized, and communications by a master controller is made only to the first IOP.    Each IOP is executing the same tasks utilizing their own clocking systems.  A method for guaranteeing that the first and second data base remain synchronized comprises the steps of communicating a message to the first IOP to update the first data base.  The second IOP eavesdrops on the communications, and when the second IOP recognizes that the message is to the corresponding primary slave IOP and that the first IOP has successfully received the message, accepts the message.  The first IOP and the second IOP execute the received message.  The master controller issues a status request type message to the first IOP, and then issues a status request type message to the second IOP.  The controller verifies that responses to the status requests indicate the update of the respective first and second data bases was completed identically, thereby providing information which permits the master controller to guarantee the first and second data base remains synchronized after the update operation.

Abstract: Fat in a confectionery chip is reduced to below about 10% by using a low-fat insoluble, non-gummy food material and small particle sugar (less than 100 microns) in combination with about 13% moisture. The sugar to non-gummy food material ratio must be between 2:1 and 4:1 and the moisture between about 10% to about 15%. Hydrated food ingredients are added to retain at least some of the moisture in the bound state. Other ingredients which may be added to the formulation include syrups, milk solids and starch. The chips can be made by simply blending the dry ingredients and adding the moisture to form a dough in the form of a dry, crumbly paste. The dough is mixed or worked up well and then formed into the desired shape. The shape is then cut into pieces similar to chocolate chips.
