Assignee:

Caliper LifeSciences, Inc. - Mountain View CA

International Classification:

G01B 11/00

US Classification:

356401, 356246

Abstract:

An optical detection system for a microfluidic device and a dry-focus microfluidic device compatible with the compact optical detection system are described. The system includes an LED; means for collimating light emitted by the LED; an aspherical, fused-silica objective lens; means for directing the collimated light through the objective onto a microfluidic device; and means for detecting a fluorescent signal emitted from the microfluidic device. The working distance between the objective and the device allows light from an external LED or laser to be brought in along a diagonal path to illuminate the microfluidic device. The dry-focus microfluidic device includes multiple channels and multiple closed optical alignment marks having curved walls. At least one of the channels is positioned between at least two of the marks. The marks are illuminated for alignment and focusing purposes by light brought in on a diagonal path from an external white LED.

International Classification:

G06Q 10/00

US Classification:

705 2, 705 3, 705 4

Abstract:

A system allows a health care provider to arrange payment at the time of service for a patient responsibility portion of a health care claim amount, even though the provider may not know what the patient responsibility portion will be until after adjudication. A health care debit card is associated with an account of the patient. At the time of service, the patient presents the card to the provider. The provider uses the card to authorize the system to hold an estimate of the patient responsibility amount in suspense in the patient's account. After adjudication, when the actual patient responsibility amount is known, a transaction set is sent to the system. The system then automatically transfers the actual patient responsibility amount from the patient's account and into the provider's bank account. Any remainder of the suspended funds is left in the patient's account. A trace number is provided so that the provider can reconcile bank statement deposits with transaction set information.
