摘要:
A vision system is provided for confirming continuously updated approach information from a global positioning system or an instrument landing system with that from an inertial navigation system. The approach information from the inertial navigation system is displayed when the global positioning system or the instrument landing system is unavailable or whose approach information is determined to be invalid.
摘要:
Communication circuitry uses a combination of Pseudo-Noise (PN) coded and non-PN coded transmission periods to represent different data values. In one embodiment, a number of data values are encoded into a smaller second number of encoded ternary values. The Pseudo-Noise (PN) codes are transmitted representing some of the encoded ternary values and no transmitted PN codes represent other encoded ternary values. The throughput of spread spectrum radio systems is increased by representing data values in fewer spread spectrum time slots.
摘要:
A wireless communication device and associated method is described. The device includes a radio and a controller to operate the radio in a normal communications range responsive to the controller binding the radio to a host in a reduced binding range, where the radio and the controller are integrated into a single chip.

Method and apparatus for enabling authentication of on-line communications. In some embodiments, a message code is embedded in an e-mail, where the message code can be used by the recipient to verify the authenticity of the e-mail or of a Web site. In some embodiments, this code can be created for a particular e-mail message; in other embodiments, the code is created as a watermark for use by a customer or other a specific user or recipient. The message code is associated with both the e-mail message and the recipient. In the case of a message-specific code, a recipient can verify the e-mail message by inputting the code via a Web server to be looked up in the database. Provision is also made for including stenographic information in graphical or other codes as further authentication when accessing a Web site.
摘要:
The invention provides a method of managing a memory of a terminal, wherein a substitute file is substituted in the memory of the terminal for at least one predetermined file, which file is previously backed-up in a member other than the terminal, the substitute file having content that is obtained at least in part from the predetermined file.

摘要:
Disclosed is a circuit, comprising a device having a minimum operating voltage, a voltage supply, wherein the voltage supply may have a value above or below or equal to the minimum operating voltage of the device, a voltage boost converter circuit having a boosted voltage output, a switch coupled between the voltage supply, the boosted voltage output and the device, wherein the switch is capable of passing one of the voltage supply or the boosted voltage output to the device, and a processing element capable of controlling the switch. A system comprising the circuit and a method of using the circuit are further described.
摘要:
The present invention includes systems and methods for customization of internet applications. Multiple levels of customization are applied to both static and functional aspects of user interface elements including, for example, tab-order, tab-over, immediate access keys, and hotkeys. Customization is also achieved with respect to searching over multiple user interfaces, presentation of information on a user interface, and the interaction model used by the internet application. Customization is enabled on any client supporting standard browser functionality.
摘要:
A method for mapping sub-surface resistivity contrasts comprising making multi-channel transient electromagnetic (MTEM) measurements using at least one electric source with grounded input current electrodes or one magnetic source with current in a wire loop or multi loop and at least one electric field or magnetic field receiver, measuring the resultant earth response simultaneously at each receiver using a known recording system, measuring the system response by measuring directly the current in the wire at the source using effectively the same recording system, using the measured system response to recover the impulse response of the earth from each measured earth response, and creating from such impulse responses a sub-surface representation of resistivity contrasts.
