摘要:
A telephone operator signal analysis and manipulation subsystem (50) is configured to be interfaced with various signal transport paths of input/output devices of the operator's (personal computer-based) workstation (12). The subsystem is operative to intercept, analyze and selectively modify signals distributed among components of the workstation, including those that may prompt an interactive response from the operator, so as to alleviate the workload of the operator, and improve the efficiency and response time of the operator position. Because the subsystem analyzes and operates only on information that is presented to and sourced from the operator, it is able to automate various functions of the operator position, including initiating the generation of personalized audio messages, without knowledge of the communication protocol of the telecommunication switch to which the operator's workstation is coupled.
摘要:
Wettable fibers or filaments are prepared from a composition having a polymer which has a wetting agent incorporated therein. The polymer is selected from the group consisting of olefin polymers, polyesters and polyamides. The wetting agent consists essentially of a glyceride selected from the group consisting of a mono-glyceride, a combination of mono-glycerides and a mixed glyceride having a mono glyceride content of at least 85 percent by weight. The fatty ester group or groups in the glyceride each have from about 12 to 22 carbon atoms. The olefin polymer is preferably polypropylene, LLDPE, LDPE and HDPE, more preferably polypropylene. The polyamide is preferably a nylon 6 and nylon 6,6. The polyester is preferably a polyethylene terephthalate and a polybuthylene terephthalate.

A progressive-scan charge-coupled device (PSCCD) camera (2) may capture an entire frame of an image of an optically readable code. The camera generates a histogram or probability distribution function (PDF) of the images and uses the histogram or PDF to automatically adjust the contrast of the image. The camera also generates a cumulative distribution function (CDF) which is used to automatically adjust the illumination intensity including the brightness of the image and the duration over which the image is obtained. The captured analog video image is converted to a digital video image which may be output over the camera's bidirectional bus interface (14) to a component outside of the camera. Updated programs, parameters and other information may be sent in the opposite direction over the bus interface to the camera. The camera may be mounted at a fixed station or may be incorporated into a portable unit, and may be hand-held and/or battery operated.
摘要:
A crankshaft and piston arrangement (10) for a combustion engine, comprising a piston (12) pivotally connected to a crankshaft (18) by a connecting rod (14), and balance means (24) comprising a connecting rod (26) and a balance arm (32, a, b, c) pivotally connected thereto, the balance arm being connectable at an end remote from the connecting rod to the engine and wherein the balance arm provides a balance mass thereby to balance vibrational forces created by the movement of the piston (14).
摘要:
An ultrasonic measuring apparatus (Fig. 2) and method (Fig. 5) to accurately determine the depth of an overlaying backfat (14-20) on an animal (8) without incurring any damage to the animal. The apparatus employs a reverse time analysis approach in which a pulse generator (28) sends a preselected ultrasonic input signal by way of a piezoelectric transducer (16) through the outer skin (12) and successively through each one of the animal's fat layer interfaces (15, 17, 20) to a preselected distance within the loin portion (22) of the animal. This reverse time approach then analyzes the resulting echo signal produced by the input signal sequentially in a direction from this loin portion toward the outer fat layers (14, 16, 18). The first strong signal within a specified range, which depends on the species, breed, age or weight of the animal to be measured, is taken as the bottom-most fat/loin transition. A microprocessor (44) is employed to measure and analyze the amplitude and contour of this signal in a direction toward the loin until it reaches a fixed point that is a prescribed percentage of the peak value of the amplitude of this signal, the magnitude of which depends on the type of animal under measurement. The value derived in this manner is an accurate measurement of the depth of overlaying backfat and is automatically displayed in digital form on a screen (46).
摘要:
A printed foam structure comprising a layer of foamed polyolefin plastic and a layer of textile ink in direct contact with the foamed plastic. The textile ink is preferably a plastisol based ink which preferably comprises a vinyl resin such as polyvinyl chloride, polyvinyl acetate, or a combination of the two as a co-polymer.
摘要:
A method and kit for the identification of an individual's genetic polymorphism pattern associated with low bone mineral density in osteoporosis is disclosed. The kit includes DNA sample collecting materials and probes for determining a genetic polymorphism pattern which is then analyzed to determine a subject's susceptibility to osteoporosis.
摘要:
A flat-panel display (10) comprising a hermetically sealed gas filled enclosure. The enclosure includes a top glass substrate (12) having a plurality of electrodes (20) and a thin dielectric film (22) covering the electrodes and a bottom glass substrate (14) spaced from the top glass substrate. The bottom glass substrate includes a plurality of alternating barrier ribs (24) and micro-grooves. An electrode (40) is deposited over each micro-groove and a phosphor (42) is deposited over a portion of each electrode coating.
摘要:
A system and method of automated shopping, including a portable bar code scanner (14) for scanning bar code indicia information on items selected to be purchased, securing the scanner in a holder (16) for limited access, and releasing the portable bar code scanner upon receiving an authorized payment card. A plurality of items for purchase are displayed in a store (30) such that a customer can select an item to be purchased from the store display. The customer scans the bar code indicia on the selected item from the store display. The payment card is debited for the purchase price of the selected item and then returned to the customer.
摘要:
A method for forming a corrugated paperboard container and a container made therefrom having a first layer of flat paperboard (12) to which is attached a second layer of contoured paperboard (14), said contoured layer having a plurality of flutes, each said flute including a first flute tip and a second flute tip, the flute rise being substantially vertical at the midpoint between said flute tips and a perforated layer of paperboard (30) having a plurality of openings (31) therein coupled with said fluted layer along said plurality of said flute tips, said forming method comprising, placing the corrugated paperboard into a stamping die, the stamping die having a male die and a female cavity shaped in the shape in which the paperboard is to be formed; pressing the paperboard between the die and the cavity to apply a pressure to the paperboard; applying heat to the paperboard simultaneously with said application of pressure; and removing said die from the cavity.
