Abstract: An optical biometer includes a light-source module, a light-splitting module, a reference-arm, a sensing-arm and a sensing module. The light-source module emits incident-light. The light-splitting module, disposed corresponding to light-source module, divides the incident-light into reference light and sensing light. The reference-arm, disposed corresponding to light-splitting module, generates a first reflected-light according to the reference light. The sensing-arm, disposed corresponding to the light-splitting module, emits the sensing light to the eye and receives a second reflected-light from the eye. The sensing module generates a sensing result according to the first reflected-light and second reflected-light. In a first mode, the sensing light is emitted to a first position of the eye. In a second mode, the sensing light is emitted to a second position of the eye.

Abstract: A pixel sensor may include a layer stack to reduce and/or block the effects of plasma and etching on a photodiode and/or other lower-level layers. The layer stack may include a first oxide layer, a layer having a band gap that is approximately less than 8.8 electron-Volts (eV), and a second oxide layer. The layer stack may reduce and/or prevent the penetration and absorption of ultraviolet photons resulting from the plasma and etching processes, which may otherwise cause the formation of electron-hole pairs in the substrate in which the photodiode is included.

Abstract: A computer implemented method extracts code for a service. Key statements are identified for the service in a source code for a region of interest in an application in response to a program selection selecting a program in the region of interest. Importance scores are determined for the key statements based on an amount of the source code executed by each of the key statements in the source code in the region of interest. An output is generated that comprises the key statements associated with the importance scores and portions of the source code executed in response to execution of the key statements. A number of code blocks derived from a number of the portions of the source code run for a key statement is added to a workbook in response to receiving a key statement selection of the key statement in the output.
