Publication number: 20090081768Abstract: An assay card and devices and methods for isolating chambers on the assay card are described. The assay card comprises a substrate formed of one or more materials, e.g., plastic, having a softening temperature, the substrate defining channels communicating with respective reaction chambers. The assay card may be heated in a region of the channels to at least the softening temperature. The softened plastic may be deformed, e.g., with a tool which may or may not also provide the heat for softening the substrate. In this manner, the plastic of the substrate may be caused to at least partially obstruct the channels, thereby isolating the reaction chambers. The invention also relates to a method of manufacturing a tool device that includes pins for heating and deforming an assay card.Type: ApplicationFiled: September 21, 2007Publication date: March 26, 2009Applicant: Applera CorporationInventors: Joon Mo Yang, David M.

Patent number: 4939705Abstract: A device for detecting the dispensing of drugs from a container in a way which eliminates false detection events due to mishandling of the container is disclosed. The device includes a container which may be opened and closed. It also contains a means for detecting the opening and separately detecting the closing of the container as well as means for measuring the time between these events and comparing this elapsed time to a predetermined standard indicative of drug dispensing event. The times of proper drug dispensing events are stored in the device for use by the health care professional following the patient's drug dosing compliance. Other opening and closing intervals which fall outside this time range give rise to an alternative response. They may be recorded with a notation of their probable error or they may be disregarded.Type: GrantFiled: November 23, 1988Date of Patent: July 3, 1990Assignee: Aprex CorporationInventors: Richard G.
