Abstract: A digital storage medium (e.g., a CDROM, a DVD, a tape, etc.) has an integrated RFID tag to store information for use in controlling access to the data stored on the digital storage medium.

Abstract: An adaptation technique is selected for use in a wireless network based on estimated throughput. In at least one embodiment, throughput is estimated for a wireless channel for both prefix adaptation and postfix adaptation. An adaptation technique is then selected based on the estimates. In some embodiments, an adaptation validity duration is determined to gauge the potential effectiveness of adaptation information associated with a wireless channel.

Abstract: Transmit parameters are adjusted for a wireless device based on link margin. In at least one embodiment, link margin is calculated as a difference between a received power level and receiver sensitivity.

Abstract: Adaptive channelization is achieved in a high throughput multicarrier system by first subdividing a high throughput channel into a number of frequency sub-channels. A channelization decision may then be made within a device as to which of the sub-channels to use for a corresponding high throughput wireless link based on channel state information.

Abstract: Channel access techniques are provided for use in a high throughput wireless network that utilizes multiple wireless channels within a single service set.

Abstract: A power amplification system within an RFID reader uses feedback to linearize a transfer function of the system. ASK modulation is used in the system. An envelope of an output signal of a non-linear power amplifier is fed back to an input where it is combined in an integrator with an ASK modulation signal to generate a pre-emphasized modulation signal. The pre-emphasized modulation signal is then applied to the power amplifier to generate a linearized output signal.

Abstract: Compact feedback schemes are presented for use in closed loop multiple input, multiple output systems.

Abstract: Techniques and structures are disclosed for allowing context-based searches to be performed from a wireless device. In at least one embodiment, a wireless device may append context-specific information, collected by at least one local sensor to a network search query to be delivered to a remote search engine when a network search is being performed. The wireless device may then receive search results from the remote search engine in response to the network search query that identify the elements of appended context-specific information that were used to perform the network search. The wireless device may then display these search results to a user.

Abstract: A tiered wireless access point has a number of different network access levels that may be provided to wireless devices seeking network access. The network access levels may differ from one another in factors such as the particular networks that may be accessed, the security level of the network connection, and/or the speed of the connection.

Abstract: An adaptive multicarrier wireless communication system, apparatus and associated methods are generally disclosed herein. In at least one embodiment, channel state information is used to perform bit loading and power allocation within a multicarrier system. In an example technique, after active subcarriers have been identified for a multicarrier channel and an initial power distribution has been made, a subset of active subcarriers may be found that exceed a channel quality performance threshold. Excess power may then be identified by determining how much power could be reduced in the identified subcarriers so that they still meet, but do not exceed the channel quality performance threshold. In one possible approach, the excess power may be re-allocated to other subcarrier subsets.

Abstract: Enhanced power management is achieved in a wireless communication system. In one aspect of the invention, power management profiles related to application type are used to achieve enhanced power management. In another aspect of the invention, the interval at which buffered broadcast and multicast traffic is transmitted to users in a network is adjusted during system operation based on a predetermined adjustment criterion to achieve enhanced power management.

Abstract: An enclosure for a wireless device includes a first compartment and a second compartment. The first compartment is to house some or all of the electronic circuitry of the wireless device and is sealed from an exterior environment. The second compartment is adjacent to the first compartment and includes one or more piezoelectric fans to provide cooling for the first compartment. The second compartment is open to the exterior environment and provides physical protection for the one or more piezoelectric fans located therein.

In at least one embodiment, a boundary scan compatible device includes functionality for detecting an intermediate signal level on an electrical node of the device (e.g., a pin on a circuit package, etc.) that is indicative of a bridging fault. Various structures are provided that are capable of detecting an intermediate signal level.

Abstract: Aggregate throughput may be improved in a wireless network by rejecting packets that have a low probability of creating harmful interference within a wireless device. In at least one embodiment, a minimum received interference power level that is likely to cause a loss of packets is first estimated. Subsequently received packets that have a received signal strength below the minimum level may then be rejected.
