  • Publication number: 20160050378
    Abstract: A pixel sensor device has a first sensing unit, a second sensing unit, a first control and reading unit, and a second control and reading unit. The first and second sensing units are disposed concentrically. The first and second control and reading units are connected respectively to the first and second sensing units for separately or simultaneously controlling the first and second sensing units to perform sensing. Since the first and second sensing units are formed by a single pixel sensing array and arranged concentrically, only a single focusing element is required to align centers of the first and second sensing units during the manufacturing process. This achieves high focus accuracy and increases precision in recognition. In the applications of fingerprint recognition and pulse measurement, the user only uses a single finger for sensing so that inaccurate focusing resulted from moving finger is avoided.

  • Publication number: 20160037095
    Abstract: An active pixel sensor device and the method thereof include an active pixel sensing array and a synchronous reading circuit. The active pixel sensing array is formed by a plurality of sensing pixels disposed in a form of an array. Each sensing pixel has a power terminal. The synchronous reading circuit connects to the power terminals of all sensing pixels, detects a summation of currents flowing through all sensing pixels, converts the summation of currents to an output signal, and outputs the output signal that represents the optical sensing information. In addition to reading each sensing pixel, the active pixel sensor device further controls the synchronous reading circuit to read the output signal corresponding to the summation of currents of all sensing pixels. The active pixel sensor device using the same active pixel sensing array can be applied to large-area sensing.

  • Publication number: 20140138075
    Abstract: A heat exchanger suitable for cooling a heat source is provided, wherein a bypass channel formed in the heat exchanger has a width greater than a width of other channels to reduce a flow resistance of a fluid and a pumping power for driving a system. That is, under the same pumping power loss, more fluid is driven to achieve a better heat dissipation effect. By applying the heat exchanger, electronic devices are bonded to a top of the heat exchanger through a supporting substrate. In this way, heat generated when the electronic devices are is transferred to the heat exchanger through the supporting substrate and dissipated to the outside via the heat exchanger. Since the distance of heat transfer is decreased, the thermal resistance generated by an interface between the devices is reduced to improve heat transfer efficiency and heat dissipation effect.
