Conventionally, processing of biological samples, which may be stored on a biological sample storage medium, is done manually with samples being tested individually. However, handling of the samples is difficult and time consuming; greater demand for storage and extraction of genetic material has led to a requirement for greater throughput. In embodiments of the present invention, there is provided a biological sample holder comprising a chamber holding a biological sample storage medium, the chamber comprising one or more openings for receiving a liquid when inserted therein. This provides a means of holding a biological sample which is easy to handle and suitable for automation, for example in an array of such holders, allowing processing of multiple biological samples in parallel.

  • Patent number: 9317922
    Abstract: A system and method for recognition of images may include the use of alignment markers. The image recognized may be a pattern from an array, a character, a number, a shape, and/or irregular shapes. The pattern may be formed by elements in an array such as an identification marking and/or a sensor array. More particularly, the system and method relate to discriminating between images by accounting for the orientation of the image. The size and/or location of alignment markers may provide information about the orientation of an image. Information about the orientation of an image may reduce false recognitions. The system and method of image recognition may be used with identification markings, biosensors, micro-fluidic arrays, and/or optical character recognition systems.

  • Patent number: 8969075
    Abstract: A method and apparatus for embedding cells that utilizes a flow-through embedding technique maximizes the efficiency of extractions and decreases time for embedding the cell fragments, minimizes cell loss, and automatically positions cell samples at the position in which a microtome blade will section them. The apparatus includes a cell flow pathway defined by an inflow tube for delivering cell fragments from a cell sample to a sample port. The sample port is in fluid communication with a tissue cassette having attached thereto a filter. The cell flow pathway is in communication with a reagent flow pathway for delivering the reagents through the sample port to the cassette. The apparatus is configured such that the application of pressure directs the cell fragments from the cell sample through the cell flow pathway, and effects delivery of the reagents through the reagent flow pathway.
