  • Publication number: 20240353888
    Abstract: The present disclosure relates to a clock signal monitoring unit comprising first, second and third flip-flops, first and second XOR gates and a delay element being functionally interconnected in a specific way. The proposed clock signal monitoring unit can detect both a rising edge glitch and a falling edge glitch. In this way there is provided an area saving device, which does not require any trimming efforts, which can save a lot of space and time. Furthermore, the clock signal monitoring unit can have low electric power consumption because it uses as few as four clocked flip-flops implemented via Register Transfer Logic having an already tuned delay element. This makes it useful for designs that use both edges of the clock for correct operation.

  • Publication number: 20240326058
    Abstract: Adapters that enable a change in the types of sample collection devices that may be inserted into and stored in sample collection device racks. The adapters are either individual adapters that fit into a rack receptacle for receiving a sample collection device, typically a tube or cylindrical container, or an array of adapters held together by connecting members that can be disposed on a sample collection device rack. With the adapters disposed in the rack receptacle, that receptacle, sized to receive securely a sample collection device of a first size, can now receive, securely, a sample collection device of a second size. The adapters are removable and washable so that racks can be modified to receive sample containers of different sizes.

  • Publication number: 20240153074
    Abstract: An imaging module to obtain an image of an entire bottle in one image frame. The imaging module places the bottle in an auxiliary mirror module (AMM). The module has a quasi-conical shaped mirror which offers a reflection of the bottle placed in the AMM. That reflection is the source of an image obtained by an imaging assembly. The imaging assembly can be a lens/camera assembly or a photo sensor that will detect photo fluorescence.

  • Publication number: 20240140700
    Abstract: A waste container includes a floor, a first side wall, a second side wall, a back wall, a front wall, a first door, and a second door. The first and second side walls are spaced apart from each other. The back wall extends between the first side wall and the second side wall. The front wall extends from the first side wall toward the second side wall such that a gap is defined between the front wall and the second side wall. The first door and the second door are each movable between an open position and a closed position. The first door in the closed position extends between the front wall and the second side wall so all the gap is blocked. The second door in the closed position extends between the front wall and the second side wall so only a portion of the gap is blocked.

  • Patent number: 11840719
    Abstract: An apparatus and associated methods of use for a controlled combination of reagents is disclosed. The apparatus includes a vessel 400, a vessel insert 220, and a cap element 200. The vessel 400 has a body portion 410 for receiving a biological sample. The vessel insert 220 receives at least one reagent therein. Preferably, the vessel insert 220 is received in a portion 420 of the vessel 400. The cap element 200 is attached to the vessel 400 to secure the vessel insert 220 in the vessel 400. During use, the vessel insert 220 is adapted to release its contents when the biological sample is introduced into the body portion 410 of the vessel 400 upon application of an intermixing force to the vessel insert 220. A variety of intermixing forces may be applied, depending upon the embodiment of the present invention and its associated methods of use.

  • Publication number: 20230001417
    Abstract: A pierceable cap 11 may be used for containing sample specimens. The pierceable cap 11 may prevent escape of sample specimens before transfer with a transfer device 43. The pierceable cap 11 may fit over a vessel 21. An access port in the shell of the pierceable cap 11 may allow passage of a transfer device 43 through the pierceable cap 11. At least one frangible layer 215, 216 may be configured with cross slits 506 in a particular cross slit geometry. The cross slits 506 may contain an openable portion 644 or be covered by a thin membrane 645. The shell 610 and frangible layer(s) 215, 216 may be integrated into a one piece cap 601, or be separate components 634. The membrane on which the cross slits 506 are placed can be flat or contoured to guide the transfer device 43 to the cross slits 506.

  • Publication number: 20220290089
    Abstract: A multi-port disposable device that can both vent a sealed culture vessel and draw a sample therefrom into a collection vessel. The multi-port disposable device has a first port configured to receive the top portion of a culture vessel and attach thereto. The multi-port disposable device has a second port configured to receive a sample collection vessel. The multi-port disposable device has first and second needles. The first needle has a cannula configured to penetrate a septum or cap of the culture vessel. Optionally, the cannula terminates in a layer of foam that carries a microbial agent such that any vapor that is transmitted from the culture vessel through the cannula when venting the sealed culture vessel is absorbed by the foam. Optionally, the ports of the disposable device are configured as sleeves. The sleeve of the first port receives a portion of the culture vessel and the sleeve of the second port receives the collection vessel.

  • Publication number: 20220089338
    Abstract: A pierceable cap may be used for containing sample specimens. The pierceable cap may prevent escape of sample specimens before transfer with a transfer device. The pierceable cap may fit over a vessel. An access port in the shell of the pierceable cap may allow passage of a transfer device through the pierceable cap. The shell receives a septum that has four half dome indentations, each indentation defining a quadrant of the septum interior. The indentations are separated by the septum floor which extends along respective first and second diameters of the septum and intersect at approximately ninety degrees. The half dome indentations guide a transfer device to the partially slitted portion of the septum floor.

  • Publication number: 20210299672
    Abstract: An apparatus for holding sample tubes for sample preparation is provided. The apparatus includes a sample tube holder with an opening to accept a sample tube. The apparatus includes a hinge assembly with a hinge plate and a hinge support, wherein the hinge plate is movable relative to the hinge support. In one example, the hinge plate pivots in two rotation directions and slides in two translational directions relative to the hinge support. The hinge plate limits vertical movement of the sample tube within the sample tube holder. In one aspect, a method includes inserting a sample tube into an opening of a sample tube holder and pivoting and sliding a hinge plate relative to a hinge support, wherein the hinge plate limits vertical movement of the sample tube within the sample tube holder.

  • Patent number: 11090228
    Abstract: Various embodiments of the present disclosure describe systems and methods for testing samples (e.g., biological samples, environmental samples, food samples etc.) for microbial contamination. For example, some embodiments describe an adapter assembly with a means to penetrate a septum of a collection vessel and permit gaseous communication between a headspace of the collection vessel and a sensor. In some embodiments, the gases in the headspace of the collection vessel can exit the collection vessel without contaminating the environment outside the system or allowing sample contamination. In some embodiments, the adapter assembly includes a membrane configured to prevent liquid in the collection vessel from contacting the sensor. In some embodiments, the adapter assembly can be used to access media inside the collection vessel for subculturing or aliquotting for another diagnostic process such as molecular diagnostics.
