Flash Memory Feet

Descriptions

The inventive step converts any of the feet under any System Unit into useful electronic gadget(s) also known as Electronic Feet Device(s) (EFD). A System Unit is any electronic and electrical device and equipment that uses Flash Memory Drive, and has feet underneath for support, such as a computer towers, Apple iPad, eBook reader, scanners, graphic tablet, and computer tablet and any other equipments or industrial equipments that uses feet for support. A laptop is use to illustrate the application of this invention.

The Electronic Feet Device(s) is an integral part of the System Unit because it is a key contributing component with the vital value to protect the underneath of the System Unit and to provide the support structure to the System Unit for the System Unit to function usefully as a fully and wholly functional stand alone and complete System Unit. The

Electronic Feet Device(s) protects the underneath of the System Unit by acting as a protection piece between the System Unit and the platform it is resting on for support.

One example is to place inside any of the feet under any System Unit a Flash Memory

Chip to function as a Flash Memory Feet. A preferred but not the only applicable function of the Flash Memory Feet is as a Flash Memory Drive. Another preferred application is to function as a Security token.

The purpose of incorporates the useful electronic gadget(s) into peripheral device(s) of different expanded functions and capabilities is to give support to the System Unit that they are attached underneath to. Currently there is no such a product that is converts a system feet into a flash memory.

A Flash Memory Drive is used as a hard drive to store rewriteable data on an

Electrically Erasable Programmable Read-Only Memory (EEPROM) that is erased and programmed in large blocks. The Flash Memory Feet fastened itself to the System Unit by securing itself to the bottom of the host controller which no standard Flash Memory

Drive does.

As an integral part of the System Unit, the Flash Memory Feet goes where the System

Unit goes: into the car, into the train, and everywhere on a business road trip, therefore the user has no problem remembering to bring the Flash memory Feet along on a business trip.

The System Unit user enjoys easy and quick access to the Flash Memory information any time by having the Flash Memory Feet underneath all the time.

i. A USB connector — provides an interface to the host computer.

i. USB mass storage controller — implements the USB host controller. The controller contains a small microcontroller with a small amount of on-chip ROM and RAM.

ii. NAND flash memory chip — stores data. NAND flash is typically also used in digital cameras.

iv. Crystal oscillator — produces the device's main 12 MHz clock signal and controls the device's data output through a phase-locked loop.

b. The typical Universal Serial Bus (USB) (fig2f, fig3f, fighc, fig10f) Flash Memory Feet (fig, fig6, fig7, fig8a, fig9c, fig10e) Printed Circuit Board Assembly (PCBA) device may also include.

i. LEDs (fig2c, fig3k,figbd) — indicate data transfers or data reads and writes..

iii. Write-protect switches — Enable or disable writing of data into memory.

iv. Unpopulated space — provides space to include a second memory chip. Having this second space allows the manufacturer to use a single printed circuit board for more than one storage size device.

v. USB connector cover or cap — reduces the risk of damage, prevents the ingress of fluff or other contaminants, and improves overall device appearance. Some flash drives use retractable USB connectors instead. Others have a swivel arrangement so that the connector can be protected without removing anything.

vi. Transport aid — the cap or the body often contains a hole suitable for connection to a key chain or lanyard. Connecting the cap, rather than the body, can allow the drive itself to be lost.

vii. Some drives offer expandable storage via an internal memory card slot, much like a memory card reader.

42. A Bluetooth Flash Memory Feet (fig1, fig6, fig7, fig8a, fig9c, fig10e) Printed Circuit Board Assembly (PCBA) will incorporate Bluetooth component into the Flash Memory Feet (fig1, fig6, fig7, fig8a, fig9c, fig10e) Printed Circuit Board Assembly Module and all its necessary components to make it a Bluetooth capable memory drive.

43.The Flash Memory Feet (fig1, fig6, fig7, fig8a, fig9c, fig10e) Printed Circuit Board Assembly (PCBA) is then placed inside a under utilize foot of a System Unit (fig8, fig9, fig10).

65. The taller (fig1g, figbg) and bigger (figle, figbe, fig7c, fig7d) shape and size of the Flash Memory Feet (fig1, fig6, fig7, fig8a, fig9c, fig10e) creates a higher and larger air gap that allows sufficient naturally air from its surrounding environment to circulate underneath (fig8b, fig9b, fig10b) the System Unit (fig8, fig9, fig10) for the System Unit (fig8, fig9, fig10) to operate at a lower heat temperature.

66. With the higher and larger air gap, the System Unit (fig8, fig9, fig10) can be easily lifted up and carried about with a better grip by inserting one fingers comfortably underneath (fig8b, fig9b, fig10b) into the larger air gap between the System Unit (fig8, fig9, fig10) and the platform the Flash Memory Feet (fig1, fig, fig7, fig8a, fig9c, fig10e).

67.The inventive step to change the coating layer on the surface bottom of the Protective Bottom Layer of the Flash Memory Feet (fig1, fig6, fig7, fig8a, fig9c, fig10e) adds further ergonomic advantages.

68. The preferred coating on the bottom surface of the Flash Memory Feet (fig1, fig6, fig7, fig8a, fig9c, fig10e) bottom layer is a smooth layer of coat to facilitate the System Unit (fig8, fig9, fig10) to slide about easily on desktop or floor for improved handling.

69. An optional coating on the bottom surface of a Flash Memory Feet (fig1, fig6, fig7, fig8a, fig9c, fig10e) bottom layer is a high friction layer of coat to prevent the System Unit (fig8, fig9, fig10) from moving about particularly useful for System Unit (fig8, fig9, fig10) that are placed in high and tight shelving .

70. The preferred material of the Flash Memory Feet (fig1, fig6, fig7, fig8a, figc, fig10e) embodiment is Acrylonitrile Butadiene Styrene (ABS) plastic. Other type of material includes rubber with ABS and metal combination.
