  • Publication number: 20080062637
    Abstract: A hard disk heat dissipating structure adopts a computer casing as its main body, and the computer casing has a containing groove at the bottom of the front end of the computer casing for containing a box body. The box body is provided for containing a plurality of hard disks and has a connecting unit at its bottom, and the connecting unit has a plurality of parallel connecting interfaces for electrically coupling and fixing the hard disks. After the hard disks are inserted into the connecting interfaces, the hard disks are parallel to each other and an interval is formed between any two hard disks to define a substantial heat dissipating passage, such that the air entering into the computer casing by natural convection carries away the operating heat produced by the hard disks to enhance the heat dissipating efficiency of the hard disks.

  • Patent number: 7266780
    Abstract: A structure and method for entering data into an electronic device (110). A deterministic data input element (130) coupled to the electronic device (110) is operable to accept a user-selected data input. Modulation of a motion of a non-deterministic data input element (140) coupled to the electronic device (11) is operable to select a varying precision of data input choices. A feedback element (120) coupled to one or more of the deterministic data input element (130) and the non-deterministic data input element (140) presents the data input choices to the user. The user enters data into electronic device (110) using one of the deterministic input element (130) and the non-deterministic input element (140) and the feedback element (120) displays a sequence of data choices to the user. The user then navigates a tree of possible data completions in order to select a particular data completion to be entered into the electronic device (110).
