摘要:
A system and method for providing multiple access levels to users of a wireless network system. The network system includes a plurality of wireless access points coupled to a network. Access points (APs) for the network may be widely distributed in various facilities, such as airports, mass-transit stations, and various businesses. The network may couple to a wide area network, such as the Internet. A portable computing device (PCD) of a user may store identification information which indicates an access or privilege level for the user of the PCD. The access level may determine the network access and/or services available to the user of the PCD. The identification information may include a System ID of the PCD. Each of the access points may be operable to “listen for” or detect the identification information of the PCD. The network system may store a list of identification information and a corresponding list of access levels. When the access point receives the identification information from a PCD of a user, the access point may determine the appropriate access level for the portable computing device using the identification information. Network access and services may then be provided to the portable computing device at the indicated level. Thus, the local network may provide various local resources which are available to users having a first access level, and users with a second access level may not be entitled to view or utilize these network resources on the network, but may be simply provided external Internet access.

A geographic based communications service system that includes a network and a plurality of access points connected to the network and arranged at known locations in a geographic region. One or more service providers or information providers may be connected to the network to provide services or information on the network. Content provided by the service providers may be based on the known geographic location of the user of a portable computing device (PCD). The known geographic location may be determined with a high degree of precision, using one or more access points and one of several different techniques. In one embodiment, the geographic location of the PCD may be determined within a radius of ten feet. Access points may be configured to determine the bearing of a signal received from a PCD, as well as the strength of the signal transmitted by the PCD. Access points may also be configured to send and receive signals with time stamps. These time stamps may be used to calculate signal travel time, thereby allowing a determination of the distance between an access point and a PCD. Each access point may include location circuitry. The location circuitry may include both analog and digital circuitry configured to perform the various methods used to determine the precise geographic location.

A method and system for maintaining the execution speed of a multiprocessor computer system includes automatically detecting a change in instruction execution rate in a disabled processor by a threshold amount and determining an amount of change in instruction execution rate to adjust an actual system-level instruction execution rate to approximate a target system-level instruction execution rate. The target system-level execution rate being pre-determined. Thereafter, the method adjusts one or more instruction processor execution rates such that the actual system-level instruction execution rate approximates the target system-level instruction execution rate to overcome the loss of the disabled processor. One embodiment of the invention involves the use of a processor key for licensing of processor resources within the computer system and offers the option of enabling a dynamic processor recovery method as well as an automatic execution rate regulation method.

A method of and system for locating a single passive underground marker type may distinguish false indications caused by other marker types. In accordance with aspects of the present invention, minimization or elimination of false marker indications may be accomplished by processing the response from a marker to determine which frequency has the largest response.

The lid support member for the lid of a high speed food processing apparatus supports a mixing baffle blade through the center of the lid. The mixing baffle blade drive shaft is hollow for introducing liquids into the mixing bowl directly over the food processing blades.
摘要:
A method for specifying an operating system (OS) file to use in a computing system after a system reboot begins by copying at least one new OS file to a system disk. An OS file to be installed is selected from the new OS files on the disk. The system is booted into the selected OS file, the selected OS file becoming the currently running OS on the system. A boot pointer on the system disk is updated to point to the selected OS file, such that any subsequent reboot will be into the selected OS file.

A method and system for dumping computer memory includes receiving an instruction to perform a dump of memory in a partitioned computer system where each partition has at least one processor and associated memory. The associated memory having a first portion and a second portion where the first portion is normally actively used for user application program or data storage. After receipt of the dump request, the source memory content is protected against corruption or contention from other program sources and copied into the second portion of memory. Preferably, the first and second portions are co-located RAM to provide speedy transfers of information. Access to the first portion of memory is then permitted by removing the protections and the user may have full access to run applications. The dump image is then transferred to any location as a background I/O task as the user executes his applications.

A method of and system for rapidly locating all passive underground electronic marker types in an area under survey may locate various marker types simultaneously. In accordance with one aspect of the present invention, a marker locator may sequentially transmit and receive multiple frequencies very quickly; alternatively, the transmitter may transmit a broadband signal on multiple frequencies.
