  • Publication number: 20150227763
    Abstract: A portable electronic apparatus includes a portable electronic device and a data access device installed on the portable electronic apparatus. The data access device includes a main body, a rotary arm and a sliding arm. The rotary arm is pivoted to the main body. When the rotary arm rotates to a folding position relative to the main body, the rotary arm is contained inside the main body. When the rotary arm rotates to a fixing position relative to the main body, the rotary arm protrudes out of the main body. The sliding arm is slidably disposed on the rotary arm so as to adjust a relative position between the sliding arm and the rotary arm. The sliding arm fixes the portable electronic device with the main body as the rotary arm rotates to the fixing position relative to the main body.

  • Patent number: 7065026
    Abstract: A data slicer capable of removing current mismatch between internal current pumps and its operating method is proposed. The data slicer includes a comparator for comparing an analog signal with a slice reference level to convert the analog signal into a digital signal, a counter electrically connected to the comparator for calculating a digital sum value according to logic values carried by the digital signal, and a voltage-adjusting circuit electrically connected to the comparator for adjusting the slice reference level. The voltage-adjusting circuit has two current pumps for shifting the slice reference level. The current generated by the current pumps can be adjusted according to the calculated digital sum value to reduce a difference between a first and a second binary values which are used to increase and decrease the slice reference level respectively.
