FireWire is also available in wireless, fiber optic, and coaxial versions using the isochronous protocols.

b. External Serial Advanced Technology Attachment (eSATA) is an external interface for Serial Advance Technology Attachment (SATA) technologies with its own power connector and power supply. The SATA interface is more streamlined than ATA and provides serial architecture for greater speed than the older parallel technology.

c. High Definition Multimedia Interface (HDMI) is a compact audio/video interface for transmitting uncompressed digital data. HDMI supports, on a single cable, any uncompressed TV or PC video format, including standard, enhanced, and high-definition video; up to 8 channels of compressed or uncompressed digital audio; and a Consumer Electronics Control (CEC) connection.

69. The advantage of using Post Adhesive is that it allows easy and fast swapping between one Electronic Feet Device(s) (EFD) of one expanded useful electronic peripheral gadget(s) function to another Electronic Feet Device(s) (EFD) of a different useful electronic peripheral gadget(s) expanded function.

70. The fitting between the five assemblies to make the Camera Feet (fig1, fig5, fig6, fig7d, fig8a, fig9d, fig10f) can be by the use of internal and external thread method or tight fit snap join method.

71. The inventive step of a taller (figbh) and bigger (figéd, figée) shape and size of the Camera Feet (fig1, figh, fig6, fig7d, fig8a, fig9d, fig10f) adds various ergonomic advantages.

72. The taller (figbh) and bigger (fig6d, figée) shape and size Camera Feet (fig1, fig5, fige, fig7d, fig8a, fig9d, fig10f) creates a higher and larger air gap that allows sufficient naturally air from its surrounding environment to circulate underneath (fig7b, fig8c, fig9b) the System Unit (fig7, fig8, fig9, fig10d) for the System Unit (fig7, fig8, fig9, fig10d) to operate with better heat dissipation.

73. With the higher and larger air gap, the System Unit (fig7, fig8, fig9, fig10d) can be easily lifted up and carried about with a better grip by inserting ones fingers comfortably under (fig9e) into the larger air gap between the System Unit (fig7, fig8, fig9, fig10d) and the platform (fig11g) the Camera Feet (fig1, fig5, fig6, fig7d, fig8a, fig9d, fig10f).

74. The inventive step to change the coating layer on the bottom surface (fig2s, fig3p) of the Bottom Protective Layer (fig2n, fig3k) of the Camera Feet (fig1, fig5, fig6, fig7d, fig8a, fig9d, fig10f) adds further ergonomic advantages.

75. The preferred coating on the bottom surface (fig2s, fig3p) of the Camera Feet (fig1, figb, fig6, fig7d, fig8a, fig9d, fig10f) Bottom Protective Layer (fig2n, fig3k) is a smooth layer of coating to facilitate the System Unit (fig7, fig8, fig9, fig10d) to slide about easily on a table top or floor for improved handling.

76. An optional coating on the bottom surface (fig2s, fig3p) of a Camera Feet (fig1, figh, fig6, fig7d, fig8a, figad, fig10f) Bottom Protective Layer (fig2n, fig3k) is a high friction layer of coat to prevent the System Unit (fig7, fig8, fig9, fig10d) from moving. Useful for System Unit (fig7, fig8, fig9, fig10d) that is placed in high and tight space shelving.

77. The preferred material of the Camera Feet (fig1, fig5, fig6, fig7d, fig8a, figod, fig10f) embodiment is Acrylonitrile Butadiene Styrene ABS plastic. Other type of material includes rubber with ABS and metal combination.
