Abstract: In one example, an apparatus comprises: a photodiode configured to generate charge in response to incident light within an exposure period; and a quantizer configured to perform at least one of a first quantization operation to generate a first digital output or a second quantization to generate a second digital output, and output, based on a range of an intensity of the incident light, one of the first digital output or the second digital output to represent the intensity of the incident light. The first quantization operation comprises quantizing at least a first part of the charge during the exposure period to generate the first digital output. The second quantization operation comprises quantizing at least a second part of the charge after the exposure period to generate the second digital output.

Abstract: An optical measurement apparatus having an improved light intensity detection performance is provided. The optical measurement apparatus includes a light receiving element capable of converting a light intensity of light to be analyzed into an electrical signal; an input terminal to which the electrical signal is input; a first amplifier and a nonlinear element configuring a logarithmic amplifier; offset resistors; a switch unit; and a controller. An inverting input terminal of the first amplifier is electrically connected to the input terminal. The offset resistors have different resistance values. The switch unit can switch an offset resistor electrically connected between the voltage source and the input terminal, of the offset resistors. An offset current is input to the input terminal by the offset resistor electrically connected between the voltage source and the input terminal. The controller measures the light intensity based on an output voltage value of the first amplifier.

Abstract: A method and apparatus for estimating capacity of a system including an energy generation system, an energy storage system or both. The method and apparatus initially estimate the system capacity based on a facility location and size. The initial estimate may be adjusted through adjustment of at least one parameter. An updated capacity estimate is generated and displayed.

Abstract: A system, apparatus and method of improved measurement of the SPF factor of sunscreen compositions. In one embodiment, a method of measuring the protection of a sunscreen composition includes exposing skin to a known intensity of light, measuring the amount of remitted light from the skin, applying sunscreen to the skin, exposing the skin to which the sunscreen has been applied the known intensity of emitted light of the spectrum of light from which the sunscreen is intended to protect the skin, measuring the amount of light remitted from the skin, and calculating a UltraViolet-A Protection Factor (UVA-PF) of the sunscreen by comparing the amount of light remitted from the skin with the sunscreen to the amount of light remitted from the skin without the sunscreen.

Abstract: A device may determine at least one metric related to a plurality of laser pulses associated with a Q-switched laser. The device may determine a statistical metric for the at least one metric related to the plurality of laser pulses. The device may determine that the statistical metric satisfies a threshold level of deviation of the at least one metric related to the plurality of laser pulses from a baseline value for the at least one metric. The device may indicate laser degradation of the Q-switched laser based on determining that the statistical metric satisfies the threshold.

Abstract: According to certain aspects, a method includes receiving an input test signal at a test input, receiving an event signal, and passing the input test signal to a test output or blocking the input test signal from the test output based on the event signal. In certain aspects, the event signal indicates an occurrence of an event in a circuit block (e.g., a memory, a processor, or another type of circuit block). The event may include a precharge operation, opening of input latches, reset of a self-time loop, arrival of a data value at a flop in a signal path, an interrupt signal indicating an error or failure in the circuit block, or another type of event.
