  • Patent number: 8671102
    Abstract: A computer-implemented method, by a computer having a computer processor, of identifying emerging risks of agents causing harms to a particular system comprises accessing, via a computer network, an electronic document database comprising document data; inputting a set of criteria, which includes a selected set of agents and a selected set of harms to a particular system, specified by a user; extracting a subset of the document data that satisfies the set of criteria; generating, with the processor, an array containing agent-harm coincidences from the extracted subset of the document data; assessing, with the processor, statistical significance of each agent-harm coincidence relative to other agent-harm coincidences; compiling, with the processor, risk data, based on the statistical significance, of agents of the selected set of agents causing harms of the selected set of harms to the particular system; and outputting the risk data.

  • Patent number: 8271540
    Abstract: An exemplary MMIC (“Multi-Mode Interviewing Capability”) survey program is a computerized tool that supports various traditional modes of collecting interview data, including telephone interviewing, written interviewing, and personal interviewing, and can be used to manage the whole interview process from questionnaire design, sample management, and fieldwork monitoring to final dataset production. The collected data may also include non-textual data from survey participants such as medical measurements of blood pressure and heart rate. Self-interviewing using the Internet is also possible which permits real time availability of results and the participation of respondents from virtually anywhere in the world, using devices such as PDA's, Smart phones and Web TV's. The MMIC survey structure is non-linear and object oriented, which permits a connection between all the building blocks of the survey to be defined on any level.

  • Patent number: 5403050
    Abstract: A sanitary device for collecting and disposing of canine fecal matter is disclosed. The device uses a scooper device with a disposable bag which is formed from a bag blank. The bag blank has a collection portion on the upper surface, and a closure device for closing a bag formed therefrom. The closure device is attached to the periphery of the lower surface. During use the scooper device maintains the collection portion of the bag blank in a substantially flat condition. The bag blank, upon mounting for use, substantially covers and protects from soilage the scooper device. After canine feces is collected on the surface of the bag blank; the bag is formed by operating the scooper device; and, then is securely closed to form a disposable bag.

  • Patent number: 5400479
    Abstract: A magnetic latch includes a first member having a protrusion and a second member engaging the protrusion to prevent the first member and the second member from sliding relatively to one another. The second member includes a first magnet to attract the first member and a first solid non-magnetic member located inside a cavity of the first magnet to enhance attraction between the first member and the second member. The second member can be provided with a backing plate to facilitate a magnetic flux path from the magnet to the magnet aperture. The second member can also include a second magnet to attract the first member and a second solid non-magnetic member located between the first magnet and the second magnet. A third solid non-magnetic member can be provided on the outer periphery of the magnets. This design provides a latch with stronger holding power.

  • Patent number: 5274474
    Abstract: A telefacsimile machine selectively operates in standard and high speed modes depending on the compatibility of equipment communicating with the telefacsimile machine at a particular time. The standard mode communication employs bit mapped pixels for both text and graphics The high speed mode distinguishes text from graphics. Scanned text characters to be transmitted in the high speed mode are compared to characters in a library. When a match is found only a code, e.g. ASCII, and the location of the character is transmitted. Graphics and unrecognizable characters are transmitted as bit mapped pixels. When a document is received in the high speed mode, the received code identifies the text character and bit-mapped pixels to be printed or otherwise recorded in a storage medium. Any desired printing resolution can then be selected for text characters.

  • Patent number: 5045640
    Abstract: A safety cover for an electrical receptacle has a receiving plate fitting over an electrical receptacle, and a cover assembly having a cover edge extending around the periphery thereof hinged to the receiving plate to pivot between a closed and an open position. The cover assembly has a plurality of locking projections spaced around the periphery of the cover assembly at positions so that they are incapable of simultaneous operation by a hand below a predetermined size. When the cover assembly is closed, locking hooks on the locking projections engage in locking hook apertures in the receiving plate structure and the cover edge is snugly abutted against the receiving plate structure, and the cover assembly can be moved to the open position only by simultaneous deformation of the cover assembly at the positions of the locking hooks sufficient to move the locking hooks sufficientyl far inwardly to free said locking hooks from the locking hook receiving apertures.

  • Patent number: 4326291
    Abstract: In a throughput error detection system, a redundant logic unit is provided along with a required logic unit for simultaneous operation therewith. The required logic unit and redundant logic unit both produce output data which, it is desired, will be the same. The output data from the required logic unit is supplied to a data bus and the output data of the redundant logic unit is supplied to a parity check digit generator. From the data received from the redundant logic unit, the parity check digit generator generates a parity check digit which is applied to the data bus along wih the data from the required logic unit. A parity checking circuit receives the data and the parity check digit from the data bus and a calculation is made by the circuit to determine if parity is correct. If parity is not correct, the checking circuit produces an alarm signal to alert a user.

  • Patent number: 4300017
    Abstract: An improved shielded ribbon cable arranged to expedite termination of the shield for grounding the shield. There is an isolator strip placed during fabrication of the cable between the conductor array and the shield; the isolator strip prevents flow of plasticized insulating material between the cover sheet and the conductor array, which usually occurs through the interstices in the shield, so that the shield can be readily separated from the conductor array to permit termination of the shield without jeopardizing the integrity of the insulation on the conductor array.
