Semiconductor apparatus and potential measuring apparatus
The present disclosure relates to a semiconductor apparatus and a potential measuring apparatus capable of preventing deterioration in signal characteristics due to parasitic capacitance caused by providing a configuration for realizing an electrode plating process when an electrode and an amplifier are provided on the same substrate. When a power source supplies a potential necessary for plating processing and a breaker reads a signal from liquid, and an amplifier amplifies and outputs the signal, the power source required for the plating processing is blocked with respect to the electrode. This is applicable to the potential measuring apparatus.

MEDICAL ANALYZER AND DIAGNOSTIC SAMPLE PROFILER
A medical analyzer and coagulation profiler performs various interrogations on specimens. A motor with reduction gearing moves and a video camera observes the samples, the cartridges or parts thereof. Changes in images are compared and recorded with a central processor that controls a display. Power supply, temperature controller, motor and gearing are mounted in a box which attaches to a smartphone. The smartphone provides the video camera, illumination and central processor that control the movement, temperature and display. The device makes testing simpler for small hospitals, clinics, ambulances, remote locations and individuals and controls a number of parallel or serial devices operating simultaneously or sequentially. A cartridge insertion actuates a circular motion to generate a blood profile based on changes. Change is analyzed with a video camera and processor such as in a smartphone and is plotted to show an amplitude and time. A smartphone provides a specific movement pattern.
CELL ANALYSIS USING CHEMFET SENSOR ARRAY-BASED SYSTEMS
Various cell analysis systems of the present teachings can measure the electrical and metabolic activity of single, living cells with subcellular addressability and simultaneous data acquisition for between about 10 cells to about 500,000 cells in a single analysis. Various sensor array devices of the present teachings can have sensor arrays with between 20 million to 660 million ChemFET sensors built into a massively paralleled array and can provide for simultaneous measurement of cells with data acquisition rates in the kilohertz (kHz) range. As various ChemFET sensor arrays of the present teachings can detect chemical analytes as well detect changes in cell membrane potential, various cell analysis systems of the present teachings also provide for the controlled chemical and electrical interrogation of cells.
System and apparatus for determining ambient temperatures for a fluid analyte system
A system and method for rapidly determining ambient temperature in a fluid-analyte meter. The meter includes a housing defining an interior space and an area for receiving a fluid sample. A processor and a first temperature sensor are disposed within the interior space of said the housing. A second temperature sensor is disposed on the housing. One or more processors are configured to determine a first temperature value from temperature data received from the first temperature sensor. The processor(s) are also configured to apply a variable current to a temperature-adjustment source such that the second temperature sensor is adjusted to a predetermined steady-state temperature value different from the first temperature value. The processor(s) are further configured to determine an ambient temperature of an exterior space of the housing based on the applied variable current, pre-determined steady-state temperature, and received first temperature values.

The thermal channel is integrated with the ETIC such that the thermal channel extends through the ETIC from the outwardly facing surface and to the thermal contact portion of the TMEC. The extension is such that the proximal contact surface of the thermal channel is outside of the ETIC and the distal surface of the thermal channel is in contact with the thermal contact portion of the TMEC. The thermal channel is thermally conductive and electrically-insulating.
