  • Patent number: 9897566
    Abstract: The present invention relates to disposable test sensors having improved sample application and measuring properties and their uses for detection, preferably, quantitative measurement, of analyte in a liquid sample like blood. In particular, the invention provides for an electrochemical biosensor which has a thin-layer fluid chamber having funnel-like shape with a novel extra wide opening as sampling entrance and a vent opening at the tip of the chamber for air escape. The thin-layer fluid chamber provides a reservoir from which a sample fluid can be drawn into it through capillary action. The extra wide sampling entrance provided by the present invention can draw blood into the chamber through any part of the opening, thus it allows easy targeting the samples with small volume, picking up smeared samples and it is more tolerant to users who jam the tip of the sensor into users' finger.

  • Patent number: 9668509
    Abstract: A retort agitation system (100) for thermal processing of products includes product carriers 102a and 102b mounted on a low friction support system 104 for reciprocal movement of the carriers along the interior of a retort. The product carriers are driven in reciprocating motion by a drive actuator system 106 that can be positioned between the carriers 102a and 102b or endwise of the two carriers 102a and 102b. A drive actuator system 106 is linked to the carriers to cause the carriers to move along opposite reciprocating paths lengthwise of the retort. Reaction actuators 108 act on the carriers in opposition to the drive actuator system 106 to apply forces on the carriers for accelerating the carriers along the reciprocating paths of travel when such carriers reach the distal and proximal ends of the reciprocating travel paths.
