Abstract: The invention provides analyzers that improve tests for detecting specific cellular, viral, and molecular targets in clinical, industrial, or environmental samples. The invention permits efficient and specific selection and sensitive imaging detection of individual microscopic targets at low magnification. Automated embodiments allow efficient walk-away, on-demand, random-access high-throughput testing. The analyzers perform tests without requiring wash steps thus streamlining engineering and lowering costs. Thus, the invention provides analyzers that can deliver rapid, accurate, and quantitative, easy-to-use, and cost-effective tests for analytes.

Abstract: A portable electronic device accessory that includes a scale assembly that is removable attachable to the portable electronic device. The scale assembly may be integral with a case assembly or may be separate for a case assembly. The scale assembly includes a scale and a platform. The scale is removable attachable to the platform in a locked or attached configuration or a detached configuration. The scale is configured to weigh objects and transmit or communicate weight data to the portable electronic device so that the number of calories may be calculated, tracked, and stored by the portable electronic device.
