Abstract: For generating a breathing alert, a method captures a video stream of a subject. The method further generates a vector time series that includes a vector for each image frame of the video stream. The method estimates of breathing signal from the vector time series. The method further determines one of large-scale motion and a breathing event of the subject based on the breathing signal. The method generates an alert if no breathing event is identified and no large-scale motion of the subject is identified within an event time interval.

Abstract: A method for manufacturing a solid-state imaging device in which a charge generator that detects an electromagnetic wave and generates signal charges is formed on a semiconductor substrate and a negative-charge accumulated layer having negative fixed charges is formed above a detection plane of the charge generator. The method includes the steps of: forming an oxygen-feed film capable of feeding oxygen on the detection plane of the charge generator; forming a metal film that covers the oxygen-feed film on the detection plane of the charge generator; and performing heat treatment for the metal film in an inactive atmosphere to thereby form an oxide of the metal film between the metal film and the oxygen-feed film on the detection plane of the charge generator, the oxide being to serve as the negative-charge accumulated layer.

The first transfer electrode portion includes a plurality of first transfer electrodes having a single-layer structure of metal material. The second transfer electrode portion includes a plurality of second transfer electrodes having a single-layer structure of polycrystalline silicon or amorphous silicon.

Abstract: Disclosed herein is a solid-state image pickup device which includes: a light-receiving unit for photoelectric conversion of incident light; and a charge transfer unit of an n-channel insulating gate type configured to transfer a signal charge photoelectrically converted in the light-receiving unit; wherein the charge transfer unit has an insulating film formed on a transfer electrode and having a negative fixed charge.

Abstract: An HCCD includes a channel 21 that transfers electric charges in an X direction, a channel 25 that transfers the electric charges in a Z1 direction, a channel 23 that transfers the electric charges in a Z2 direction, and a channel 22 that connects the channels 23, 25 to the channel 21. The following relation is satisfied in impurity concentration of the channels: channel 21 channel 22 channel 23, 25. A fixed DC voltage is applied to branch electrodes 12a, 12b above the channel 22. The channel 22 has protrusion portions 19 that protrude inward from an outer circumference, which connects T1 and T2, and an outer circumference, which connects T3 and T4. The protrusion portions 19 causes charges below the transfer electrode 11b to move near the center of the channel 22 in a Y direction. Thereby, the travel distance of the charges in the channel 22 is reduced.
