Title: Methods and apparatus for optically determining the acceptability of products
Inventor: COX KENNETH A
IPC: G06V10/70
Filed: 1992-02-26
Abstract: The acceptability of the appearance of objects such as consumer products is determined by forming an initial discriminant function as a composite of a relatively small number of images which are known to be acceptable. This initial discriminant function is then used to gather statistical information about how a first relatively large number of images compares to the initial discriminant function. Thereafter, this statistical information is.used to select or aid in the selection of acceptable images from a second relatively large number of images, and the images selected as acceptable are used to refine the discriminant function. The refined discriminant function is then used (e.g., during actual product inspection) to determine which objects have an acceptable appearance and which do not.

Title: Vernier voltage-to-digital converter
Inventor: FRICK ROGER L
IPC: G01L9/12
Filed: 1990-08-30
Abstract: A voltage-to-digital converter comprising a storage circuit for providing a storage capacitance with a plurality of selectable magnitudes. The storage circuit provides a charge output representative of applied voltage input signals and the selected capacitive magnitude. A charge accumulation circuit is coupled to the charge output. The total charge accumulated is proportional to the integral of the amount of charge discharged from the storage circuit. The charge accumulation circuit provides a balance output representative of a comparison of the accumulated charge and a reference charge. A control circuit is coupled to the balance output for providing feedback signals as functions of the balance output for periodically charging and discharging the storage capacitance, whereby a first sequence of charge packets is provided on the charge output for driving the accumulation of charge toward the reference within a first set of limits when a first capacitive magnitude is selected in the storage circuit, and whereby a second sequence of charge packets is provided on the charge output for driving the accumulation of charge toward the reference charge within a second set of limits when a second capacitive magnitude is selected in the storage circuit. A calculation circuit is coupled to the feedback circuit for counting the number of charged packets generated in a measurement cycle. An output circuit provides an output indicative of the voltage input signals as a function of the number of packets counted.

Title: Sensor for detecting gas-liquid flow patterns
Inventor: CHANG VICTOR
IPC: G01D5/20
Filed: 1992-05-19
Abstract: ABSTRACT OF THE DISCLOSURE    The sensor comprises a movable sensing element which is at least partially immersed within the fluid flowing through the pipeline, two electric coils for detecting movement of the sensing element as a result of a displacement due to the flow of fluid; and an electrical means for generating an electric signal representative of the detected fluid in response to the detected movement of the sensing element.  In a preferred embodiment of the present invention the sensing element comprises a plate of non-magnetic material supported within a housing structure for oscillatory movement.  The sensing element further comprises a head member attached to one end of the plate which is formed from a magnetic material such as a ferromagnetic material or a permanent magnet.  As fluid strikes the sensing element, the head member is displaced from its neutral position.  The two electric coils are supported within a casing for generating a magnetic field.  By monitoring changes in the magnetic field due to displacement of the magnetic head member, various properties of the fluid flow in the pipeline can be determined.

Title: Comminuted meat and meat products with artificial edible adipose, methods of making the same and saccharide/protein gels and emulsions for those adiposes and other products
Inventor: COX JAMES P
IPC: A23L13/40
Filed: 1991-02-22
Abstract: COMMINUTED MEAT AND MEAT PRODUCTS WITH ARTIFICIAL EDIBLE ADIPOSE, METHODS OF MAKING THE SAME AND SACCHARIDE/PROTEIN GELS AND EMULSIONS FOR THOSE ADIPOSES AND OTHER PRODUCTS          Abstract of the Disclosure Meat products which, before and after preparation, have the aroma, appearance and taste of meat products of a comparable character but contain substantially less cholesterol and/or saturated fats and typically retain their juiciness and taste upon standing after being cooked for a longer time than conventional meat products do.  The reduced cholesterol/saturated fat content is realized by in part substituting for natural adipose an artificial adipose based on an emulsion of:  (a) blood plasma, preferably from the same specie of animal as the meat from which the product is made and (b) cholesterol-free or low cholesterol fats and oils which may also be free of saturation or have a low degree of saturation.  Various agents can be employed to convert the blood plasma/lipid emulsion to a gelatinous form in which it closely resembles a natural adipose and the adipose can be formulated so that it will become colorless as the product is prepared by cooking like natural adipose does.  The adipose can also be used for other purposes.  The artificial adiposes contain a protein/saccharide system which can also be used to provide a host of other new and valuable products including skins and membranes, dewatering agents, coagulants and stabilizers for lipid/aqueous carrier systems with high concentrations of lipids.

Title: Telecommunication system
Inventor: PROCTOR PETER N
IPC: H04M1/72511
Filed: 1993-07-14
Abstract: ABSTRACT OF THE DISCLOSURE            A telecommunication  system  includes a number of radio base stations connected to a telephone network, the base stations forming a link to the network for a number of cordless  telephones.   Each base  station determines  in which of a number of predetermined signal strength bands the signal strength of a signal produced by a cordless telephone and received by the base station lies.  If the received signal strength is in the highest signal band, the  base  station  sets up a  link between the cordless telephone and the telephone network.   If  the  received signal strength lies in a lower band, the base station stores an indication of the signal,  and scans through the communication channels  available between the base station and the cordless telephones to determine whether a new incoming signal lies in the highest signal band, or whether by increasing  the  rand of  the band  of  a stored signal, the highest signal band is reached.
