1. A host structure comprising:
- a compartment disposed at least partially within the host structure, the compartment being configured to reversibly engage with a fluidic optical cartridge, the compartment including an interlock feature configured to reversibly engage the fluidic optical cartridge, wherein the fluidic optical cartridge comprises;
a fluidic structure that includes a channel through which objects can travel along respective paths during operation of the apparatus, the channel having at least one transparent wall; and
at least one optical component configured to provide measurement light to the objects traveling through the channel, the output light emanating from the objects in response to the measurement light, the host structure further comprising a source of the measurement light;
a waveguide configured to deliver measurement light to the compartment;
a detector configured to receive output light emanating from the fluidic optical cartridge and to generate one or more electrical signals in response to the output light; and
electronics to process the electrical signals from the detector.

Abstract
Embodiments are directed to a host structure that includes a waveguide configured to deliver measurement light to a compartment at least partially within the host structure. The compartment is configured to reversibly engage a fluidic optical cartridge. The host structure also includes a detector configured to receive and process output light emanating from the fluidic optical cartridge as well as electronics to process signals from the detector.

19. A method comprising:
-
operating an interlock feature of a compartment of a host structure, operation of the interlock feature reversibly engaging a fluidic optical cartridge in the compartment of the host structure, wherein the host structure comprises; a waveguide configured to deliver measurement light to a compartment at least partially within the host structure, the compartment being configured to reversibly engage a fluidic optical cartridge; at least one detector configured to receive output light emanating from the compartment and to generate one or more electrical signals in response to the output light; electronics configured to process the electrical signals, wherein the fluidic optical cartridge comprises; a fluidic structure that includes a channel through which objects can travel along respective paths during operation of the apparatus, the channel having a transparent wall; and at least one optical component configured to provide the measurement light to the objects traveling through the channel; drawing analyte fluid into the fluidic structure; measuring characteristic properties of the objects in the fluid based on the electrical signals; and dispensing the analyte fluid from the fluidic structure. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
