A system and method is provided for detecting wireless access devices coupled to local area network of computers. The method includes coupling a sniffer device to a local area network. The method includes transferring one or more packets to be directed to a selected device over the local area network. The selected device is preferably coupled to the local area network. The method includes intercepting the one or more packets to be directed to the selected device at the sniffer device. Moreover, the method includes deriving information from the intercepted one or more packets using the sniffer device. The method can generate one or more marker packets in a selected format using the sniffer device. The marker packets are provided based upon at least a portion of the information derived from the intercepted packets. The method includes transferring the one or more marker packets from the sniffer device over the local area network to the selected device and monitoring an airspace within a vicinity of the selected device using one or more sniffer devices.

The invention relates to a method for protecting a touch screen of a hand held electronic device having a front face that includes a touch screen portion and a non-functional band. The method of the invention comprises providing a touch screen protector comprising a film having front and back sides, an outer perimeter that corresponds to that of the device, and a transparent window; and an exposed adhesive along the outer perimeter of the film surrounding the transparent window; and removably attaching the protector upon the outer perimeter of the front face of the device via the exposed adhesive to form an enclosed air space between the transparent window of the film, the adhesive and the touch screen portion of the device.

A transparent illuminated infusion cannula is provided for illuminating an area during eye surgery. An optical fiber may be spaced a certain distance away from the cannula such that fluid flow around the distal end of the fiber and into the transparent cannula may occur with a much higher flow rate than what had previously been possible. The fiber cannula airspace may be optimized so that the cross-sectional area of the fluid conduit remains substantially constant in order to achieve a best compromise between high light transmittance and high fluid flow rate.

There is provided a method for identifying, at the moment of verification, the situation of a threat to a protected ground, airspace and / or sea limits by an approaching ground vehicle, aircraft or sea-going vessel. The method includes an authorized driver / pilot / captain to select first state in which the vehicle, aircraft or sea-going vessel is not considered to present a threat and a second state in which the vehicle, aircraft or sea-going vessel is considered to present a threat. The method further provides entering the first and second PIN codes into a smart card for generating a One Time Indicia (OTI) for each of the PIN codes and disclosing the state associated with each of the first and second OTI codes to at least one control center. Upon the control center receiving an OTI code, the control center obtains positive identification of the driver / pilot / captain and the degree of the threat that the vehicle, aircraft or sea-going vessel presents.

An automatic channel selection (ACS) process enables an access point to determine a best channel available, i.e., the channel with a least amount of interference, for it operation. When ACS is enabled, the access point scans frequencies for all neighboring access points and their signal strengths. Based on this data, the access point then determines which frequency is least likely to be interfered with by these other access points. The access point switches itself to this frequency and begins operation. During normal operation, the access point may periodically rescan the air space and reevaluate its current operating channel. Preferably, every neighboring access point has its own channel, and the co-channel interference levels should be low enough so that there is a maximum coverage and high throughput for the network. If these characteristics cannot be achieved, the access point may then adjust its power automatically to reduce the interference level in the network. This automatic power adjustment (APA) feature preferably operates across a set of access points, each of which has the function. In this manner, the transmitting power of the neighboring access points in the wireless network is “cooperatively” adjusted to minimize the channel interference and maximize the coverage and throughput for the network. A method of determining optimal access point locations for access points that perform the ACS and APA functions is also described.
