Publication number: 20240353888Abstract: 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.Type: ApplicationFiled: April 19, 2024Publication date: October 24, 2024Inventors: Andreas Lentz, David Paul Price

Publication number: 20240326058Abstract: 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.Type: ApplicationFiled: August 8, 2022Publication date: October 3, 2024Applicant: BECTON, DICKINSON AND COMPANYInventors: Alyssa Shedlosky, Ammon David Lentz, Michael T.

Publication number: 20240153074Abstract: 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.Type: ApplicationFiled: March 9, 2022Publication date: May 9, 2024Applicant: BECTON, DICKINSON AND COMPANYInventors: Jingyun Zhang, Ammon David Lentz

Publication number: 20240140700Abstract: 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.Type: ApplicationFiled: October 27, 2023Publication date: May 2, 2024Inventors: David Lentz, Derek Ruckman

Patent number: 11840719Abstract: 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.

Publication number: 20220290089Abstract: 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.Type: ApplicationFiled: August 5, 2020Publication date: September 15, 2022Applicant: BD KIESTRA B.V.Inventors: Brent Ronald Pohl, Franciscus Hermannus Feijen, Robert Edward Armstrong, Ammon David Lentz

Publication number: 20220089338Abstract: 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.

Patent number: 11090228Abstract: 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.Type: GrantFiled: August 18, 2017Date of Patent: August 17, 2021Assignee: BECTON DICKINSON AND COMPANYInventors: Ammon David Lentz, Brent D.
