In a network security system, clients search for neighbor access points (APs) in order to establish wireless connections to a LAN. As a result of the search, each of the clients dispatches a list of access points obtained to a controller. The controller detects non-registered access points by comparing a list of previously registered access points with the lists dispatched by the clients.

A method that utilizes software and hardware mechanisms to meet the FCC requirement for a U-NII antenna to be an integral part of the device in which it operates, while providing wireless ready U-NII devices and CRUable U-NII radios. Enhancements are made to the software BIOS, including the inclusion of a table of approved radio-antenna PCI ID pairs to create an authentication scheme that verifies and authenticates the radio and antenna combination as being an FCC-approved unique coupling during boot-up of the system. The BIOS also comprises an OEM field that stores an encrypted secret key utilized to complete a second check of the radio model placed in the device. During boot up of the device, the PCI ID pairs from the BIOS are compared against the PCI ID of the radio and the secret key is checked against the radio model. Only a system with an approved combination of radio and antenna is allowed to complete the boot process, indicating an FCC approved device-antenna-radio combination under the 'integral' requirement.

A computer device, according to the present invention, includes: a power source judging means for judging whether power is supplied from an AC power source to the computer device capable of connecting with a wireless communications module which transmits and receives data to/from an access point; and a control means for controlling the timing of measuring the strength of connection with the above described access point based on judgment by the above described power source judging means. Therefore, by setting the timing of measuring the strength of connection with the access point based on whether or not the computer device is used at an almost fixed location, which in turn is judged by distinguishing the type of power source, it is possible to change the amounts of data transmitted and received by the wireless communications module.

A method that utilizes both software and combination software and hardware mechanisms to comply with the FCC requirement for an U-NII antenna to be an integral part of the device, while providing CRUable dual mode wireless cards and wireless-ready U-NII devices. Enhancements are made to the system BIOS and Device Driver, and two new software-implemented utilities are provided to create authentication schemes that verify and authenticates the CRUable dual mode U-NII radio and antenna combination as being an FCC approved unique coupling during operation of the system. The system boots with only ISM transmission capability and is allowed to complete a U-NII transmission request only with an approved U-NII radio-antenna combination.

An audio apparatus that enables audio output and volume to be controlled according to the usage situation is provided for. In an audio apparatus of the present invention, certain hypothetical connection situations are compared with actual connection situations, and when the actual connection situation matches a described hypothetical connection situation, the audio volume corresponding to that hypothetical connection situation is extracted from storage, and is used as the audio volume to be output from the audio apparatus.

A method that utilizes software means to meet the FCC requirement for an U-NII antenna to be an integral part of the device in which it operates, while providing wireless ready U-NII devices and CRUable U-NII radios. Enhancements are made to the system BIOS, including the inclusion of a table of PCI IDs and secret key pairs. The CRUable radio includes a pair of validation registers (VRs) and an EEPROM storing an PCI ID and secret key of an approved device. During boot up of the device, the PCI ID and secret key from the device's BIOS are compared against the PCI ID and secret key stored in the radio's EEPROM. The first comparison completes a radio-to-device authentication in the device, while the second comparison completes a device-to-radio authentication in the radio. U-NII transmission capability is enabled only when both parameters match, indicating FCC approved device-antenna-radio combination under the 'integral' requirement.

A data processing apparatus for generating a desired color image by use of an easy user interface. The user interface includes a screen and an input apparatus having at least a pointer control apparatus. The pointer control apparatus is used for controlling the position of a pointer on the screen, coloring the pointer in a first color in response to the input apparatus, moving the pointer to a desired position on the screen in response to the pointer control apparatus, and changing the color of an area pointed by the pointer, in response to the input apparatus, into the color which is under the influence of the first color.

In an initial set up sequence, N pels of an original image are stored in N memory positions of an input buffer. The N pels are converted to M pels, which are stored in M memory positions of an output buffer, where M and N are integers larger than 0. In the case of N&lt;M, an enlargement of the original image is made, and in the case of N&gt;M, a reduction of the original image is made. An address counter pointing to an address of a memory position of the input buffer is initially reset to 0. An address counter pointing to an address of the memory position of the output buffer is also reset to 0. The values -N, M, and an initial sum value S (where S is integer satisfying -N.ltoreq.S&lt;M) are initially stored in three registers, respectively. The initially stored sum value S is repeatedly updated to control the scaling up operations or the scaling down operations. There is a first device which determines or checks whether the sum value is negative, or not. The first device generates a first signal indicating that the sum value is not negative or a second signal indicating that the sum value is negative. A second device responds to the first signal to store or move the pel data in a memory position of the input buffer pointed to by the address counter into a memory position of the output buffer pointed to by the address counter, to update the sum value by adding the value -N to the sum value and to increment the address of memory position of the output buffer; and which responds to the second signal to update the sum value by adding the value M to the sum value, and to increment the address of the memory position of the input buffer. A control device is provided to repeatedly control the above operations until the M pels of the scaled image are formed.
