Abstract: An electrode controls transmittance of a blocking layer over a photodiode of a pixel sensor (e.g., a photodiode of a small pixel detector) by changing oxidation of a metal material included in the blocking layer. By using the electrode to adjust transmittance of the blocking layer, pixel sensors for different uses and/or products may be produced using a single manufacturing process. As a result, power and processing resources are conserved that otherwise would have been expended in switching manufacturing processes. Additionally, production time is decreased (e.g., by eliminating downtime that would otherwise have been used to reconfigure fabrication machines.

Abstract: A heat ventilating chair includes a backrest unit, a seat unit, and a connecting unit connecting the backrest unit to the seat unit. One of the backrest unit and the seat unit includes a hollow member having an air pump, a pressure valve, and a channel that communicates fluidly the air pump and the pressure valve. The connecting unit is connected between the air pump and the other one of the backrest unit and the seat unit. The connecting unit drives the air pump to expel hot air in the channel to the ambient via the pressure valve when the backrest unit is forced to incline rearward. The connecting unit drives the air pump to draw ambient cool air into the channel via the pressure valve when the backrest unit is restored from a rearwardly inclined state.

Abstract: A silicon steel core for transformers or choke coils includes at least one silicon steel sheet core which has at least two sets of silicon steel sheets that have respectively a magnetic flux section of a different length such that when two sets of the silicon steel sheet cores are coupled, the magnetic flux sections form at least two gaps of different intervals. Thereby the silicone steel sheet sets of a smaller gap can provide adequate electric induction for the transformers or choke coils while the silicone steel sheet sets of a greater gap can reduce the saturated condition when the transformers or choke coils are in the high load condition.

Abstract: A compensation circuit for a power supply comprises a compensation component connected in parallel to a PFC choke used by a rectification unit of a power supply, said compensation component lets the current through the PFC choke pass through the compensation component (charging the compensation component) before the current is connected due to the counter electromotive force effect, and brings the angle of current connection forward (which is the operating phased current of the compensation current), and discharges the PFC choke when the compensation component is at the antiphase of the voltage; such charging current and discharging current are equal (balanced) and thus improving the completeness of the current waveform.

Thereby the silicone steel sheet sets of a smaller gap can provide adequate electric induction for the transformers or choke coils while the silicone steel sheet sets of a greater gap can reduce the saturated condition when the transformers or choke coils are in the high load condition so that the transformers or choke coils can reach a required electric induction without increasing the number of the silicon steel sheets or copper coils of the transformers or the choke coils, and prevent the transformers or choke coils from occurring saturation on the entire magnetic core in the high load.

Abstract: A silicon steel core spacing structure for improving induction comprises a shielded copper spacer between the magnetic flux sections of two silicon steel core, and the magnetic reluctance of such copper spacer is relatively low that can guide the traveling path of the magnetic line of force, and thus lower the magnetic flux density passing through the copper spacer. Therefore, the induction outputted from a transformer or a choke coil not only can comply with the safety tests, but also can improve the light-load power and the heavy-load power.

Abstract: An optical system of fingerprint image capture apparatus comprises an optical platen substantially in a flat shape, a source light, and an image sensor. The optical platen includes a generally planar contact face having a dull rough surface against which a finger is placed, and a generally planar viewing face at the side of which is placed the image sensor and the light source. An incident light from the light source that strikes a region of the contact surface touched by a fingerprint ridge is scattered and passes through the viewing face to be substantially captured by the image sensor. An incident light that strikes a region of the contact face corresponding to a fingerprint valley is scattered and further passes out of the optical prism by refraction. The fingerprint ridge thereby appears as brighter regions and the fingerprint valley as darker regions.

Abstract: A method of manufacturing silicon steel sheets for current-resistant coils comprises the steps of: transporting a silicon steel sheet material with the directional property to a punching machine, punching the silicon steel sheet material to form a formed first silicon steel sheet and a formed second silicon steel sheet which have directional property normal to the formed first silicon steel sheet and the formed second silicon steel sheet, and winding a coil on the formed second silicon steel sheet. When power supply is input, the coil and the formed first silicon steel sheet and the formed second silicon steel sheet will generate a magnetic force direction normal to the directional property of the silicon steel sheet material. Thus the current-resistant coil can withstand greater input power supply, deliver more stable output and better meet PFC requirements.
