An Internet appliance has added hardware and software functionality to allow communication where a dialing action request is authorization is verified using a personal identification means (PIM). A user first selects a communication access number by requesting a dialing action on a actual or a virtual keypad or by clicking a 'hot spot' on a Web page. Selecting an access number (e.g., dialing of a telephone number), alerts the user of the Internet appliance of the selection process whether the user instigates or the selection is attempted from a remote device using the Internet appliance facilities. Either method will trigger software commands that prompt the user to enter a PIM either to authorize his own use or another one's use of the Internet appliance. The PIM may comprise, but is not limited to, keying in a personal identification number (PIN), a biometric identification, or a smart card stored number. The PIM is correlated to an authorization means that verifies that the user so identified is authorized to make or allow the prescribed connection. The Internet appliance has a security protocol that is used to encrypt and decrypt the PIM data. Also the device drivers used to execute a dialing action are also encrypted by the security protocol and are only decrypted on granting of authorized use of the Internet appliance. If the user so requests and is authorized, they may also select to use the security protocol to execute secure communication. The security protocol includes but is not limited to a Public/Private symmetric key technology.

A multi-fan apparatus and method incorporates mutual active cancellation of fan noise and/or vibrations. The multi-fan apparatus includes two or more fans circuits, each comprising a fan, a fan speed controller and a separate tachometer, and a fan phase controller. The phase controller is connected to at least one fan speed controller and to each tachometer. Each fan's speed is independently and dynamically maintained at the same set speed by the fan speed controllers using an independent control loops. A noise and/or vibration cancellation phase difference between fans is determined in order to achieve destructive interference of pressure waves and, thus, noise and/or vibration reduction, in pre-determined region of a system incorporating the multi-fan apparatus. The phase controller establishes and maintains this cancellation phase difference between the fans based upon feedback from the tachometers.

Mutual active cancellation of fan noise and vibration

A method for frequency modulation synthesis and apparatus for performing the method. The method uses additions rather than multiplies and therefore saves the space and cost of multipliers in circuit implementations. The method saves further resources by using the coordinate rotation digital computer (CORDIC) algorithm to acquire sine values as opposed to an extensive sine look-up table. The method can be implemented with either a dedicated digital circuit or a programmed special purpose processor such as a digital signal processor. The hardware for implementing the method is normally integrated onto a semiconductor device.

A system and method of partitioning and providing communication to allow ISA Plug and Play protocol logic functions to be shared across multiple integrated circuits on a single Plug and Play compliant ISA bus adapter card as defined by the Plug and Play ISA Specification in a manner that minimizes the duplication of function.
