  • Publication number: 20240072461
    Abstract: A system comprises a printed circuit board (PCB) substrate and a housing. The PCB substrate has a plurality of light emitting diodes (LEDs), a first plurality of electrical conductor portions and a second plurality of electrical conductor portions. The housing has a first side and a second side opposite the first side. The housing has on the first side a first wire terminal and a second wire terminal. The housing has on the second side a first conductor contact and a second conductor contact. The housing is configured to be attachable to the PCB substrate so that first conductor contact is electrically coupled to an electrical conductor portion from the first plurality of electrical conductor portions and the second conductor contact is electrically coupled to an electrical conductor portion from the second plurality of electrical conductor portions.

  • Patent number: 11369963
    Abstract: Integrated devices that include a sample preparation component integrated with a detection component are disclosed. The sample preparation component may be a digital microfluidics module or a surface acoustic wave module which modules are used for combing a sample droplet with a reagent droplet and for performing additional sample preparation step leading to a droplet that contains beads/particles/labels that indicate presence or absence of an analyte of interest in the sample. The beads/particles/labels may be detected by moving the droplet to the detection component of the device, which detection component includes an array of wells. Additional analyte detection devices configured to operate an analyte detection chip to prepare a test sample and to detect an analyte related signal from the prepared test sample in the analyte detection chip are disclosed.

  • Publication number: 20210325334
    Abstract: Methods, devices, and systems for analyte analysis using a nanopore are disclosed. The methods, devices, and systems utilize a first and a second binding member that each specifically bind to an analyte in a biological sample. The method further includes detecting and/or counting a cleavable tag attached to the second binding member and correlating the presence and/or the number of tags to presence and/or concentration of the analyte. Certain aspects of the methods do not involve a tag, rather the second binding member may be directly detected/quantitated. The detecting and/or counting may be performed by translocating the tag/second binding member through a nanopore. Devices and systems that are programmed to carry out the disclosed methods are also provided. Also provided herein are instruments that are programmed to operate a cartridge that includes an array of electrodes for actuating a droplet and further includes an electrochemical species sensing region.

  • Patent number: 10024734
    Abstract: A system and method are disclosed for controlling an inventory of point-of-care diagnostic devices. The inventory includes a main inventory and at least one subinventory. Each device has an ambient temperature shelf life. Data associated with the devices is entered, including: the current quantity and predetermined minimum quantity of devices in the main inventory; and the current quantity and predetermined minimum quantity of devices in the subinventory. A first timestamp is associated with each device when the device is transferred from the main inventory to the ambient temperature subinventory. The first timestamp is compared to a second timestamp prior to use of the device to determine whether the device's ambient temperature shelf life is exceeded. The current quantity of devices in the subinventory is updated in response to an event that causes a change in the current quantity of devices in the subinventory.
