The camera device includes a lens module, a light-guiding tube and a photosensitive sensor; the light-guiding tube is arranged at a periphery of a light-entering hole of the lens module; the light-guiding tube is connected to the photosensitive sensor; and the photosensitive sensor is connected to a circuit board of the lens module.

An attachment includes an abutment plate portion and a retaining portion. The abutment plate portion cannot be inserted into a mounting hole. The abutment plate portion includes an insertion hole in a middle portion thereof. The retaining portion is disposed on a back side of the abutment plate portion. The attachment is mounted on the mounting hole by the retaining portion inserted into the mounting hole, the abutment plate portion abutted against a peripheral edge portion of the mounting hole from a front side and a lock portion of the retaining portion engaged with the peripheral edge portion of the mounting hole from a back side. A body portion of a solar radiation sensor is inserted into the insertion hole, a head portion of the solar radiation sensor is abutted against the abutment plate portion and at least one catch claw of the body portion of the solar radiation sensor is engaged with the lock portion of the retaining portion.

A dialysis system is provided that includes a dialysis machine and a potassium sensing device that is configured to measure the concentration of potassium in the patient's blood, in spent dialysate resulting from treating the patient, or in both. The potassium sensing device can be configured to generate a sensed value of the concentration of potassium. A control and computing unit, including a processor and a memory, is configured to receive the sensed value, compare the value with one or more values stored in the memory, and generate a control signal based on the comparison. A potassium infusion circuit uses the control signal to infuse supplemental potassium solution into the treatment dialysate, a replacement fluid, or both. The memory can include stored patient-historical and population data.

A method, apparatus, and computer-readable storage medium for analyzing component separation/mass spectrometer data for a sample having known characteristic includes analyzing reference ion data for a relationship between ion mass, retention time, and intensity. The analyzed data is added to a repository, wherein each ion therein has an intensity maxima within a characteristic retention time range for a characteristic ion mass. If the reference ion is in the repository, the range is modified according to the characteristic retention time of the reference ion intensity maxima. Based on the known characteristic, an ion expected in the sample is selected from the repository, and sample data is compared to data for the ion selected from the repository to determine whether the ion is present in the sample. The range in the repository is then modified according to the characteristic retention time of the intensity maxima for the ion present in the sample.

An ultraviolet optical system includes an objective lens group that captures ultraviolet light for each angle from an ultraviolet light source and forms an intermediate image, and an imaging lens group that re-images the intermediate image. Neither the objective lens group nor the imaging lens group has a cemented surface, and all lenses included in the objective lens group and in the imaging lens group are single lenses that transmit ultraviolet light having a wavelength of 300 mn or shorter. A light distribution measuring apparatus includes the ultraviolet optical system and a sensor, and outputs light distribution of the ultraviolet light source by using a signal obtained by the sensor. The ultraviolet optical system is positioned such that the intermediate image is re-imaged on a light receiving sensor surface, and the sensor has light receiving sensitivity to ultraviolet light having a wavelength of 300 nm or shorter.

One aspect of the present technology relates to a device. The device includes a sensor having an anode and a cathode. An operational amplifier (op-amp) having a single-ended output terminal, a non-inverting input, and an inverting input, is operatively coupled to one of the anode or the cathode of the sensor by the inverting input. A feedback resistor having a resistance of at least approximately one giga-ohm (1 GΩ) is operatively coupled between the single-ended output terminal and the inverting input of the op-amp. A grounded field shunt is positioned adjacent to the feedback resistor. The op-amp, grounded field shunt, and feedback resistor are disposed within an electrical shield enclosure. The single-ended output terminal of the op-amp terminates outside of the electrical shield enclosure.
