Abstract: Example embodiments provide various techniques for storing and recovering a cryptographic key identifier that may be used to recover encrypted data. The cryptographic key identifier may be stored with the encrypted data itself. In an example, the cryptographic key identifier may be stored in particular blocks on a logical disk that are specifically designated to store the cryptographic key identifier. To store the cryptographic key identifiers in the designated blocks, the data within the blocks is compressed to fit the cryptographic key identifiers within the blocks. This cryptographic key identifier can be recovered at a later time by locating the designated blocks and retrieving the cryptographic key identifier from the blocks.

Abstract: An apparatus and method for operating a Multiple Input Multiple Output (MIMO)-capable subscriber node are disclosed. In one embodiment, an apparatus includes a MIMO-capable physical layer transceiver and a Medium Access Control (MAC) layer block that measures a received transmission to determine channel conditions. Upon receiving a transmission wherein said channel conditions meet specified conditions, the MAC layer block requests an access point for permission to switch between a non-MIMO mode and a MIMO mode, and upon receiving permission, the MAC layer block switches between the non-MIMO mode and the MIMO mode. An apparatus for operating an access node is also disclosed.

Abstract: A method for evaluating number of additional admissible calls for use in call admission control includes tracking a percentage of channel busy time and transmission time of downlink and uplink voice packets, receiving a call admission request, and calculating the number of admissible calls. The number of admissible calls is calculated based on a channel bandwidth requirement determined from the percentage of channel busy time and a voice packet queuing requirement determined from the transmission time of downlink and uplink voice packets. The call admission request is approved if the number of admissible calls is greater than one and rejected if the number of admissible calls is less than one.

Abstract: A multi-element refractive/diffractive lens system, especially useful in an interferometer of the Fizeau type for forming a partially reflective end of the cavity and focusing collimated laser light at a focus in the cavity, uses a plurality of lens elements all of which are plano concave or plano convex singlets and may be either spherical or cylindrical. The lens has a diffractive element which compensates for aberrations due to the refractive elements of the lens system and enables the lens system to be formed from relatively few refractive elements which are all plano-convex or plano-concave singlets thereby providing cost savings arising out of the reduction in the amount of glass material and number of lens elements. Since the lens system is especially suitable for use in a Fizeau type interferometer, it may be of the type called a Fizeau lens.

Abstract: In an example embodiment, there is disclosed a technique that enables a wireless device to achieve coexistence with an interfering source. The wireless device determines when interference is present and not present during a service period and reports the duration of interference free interval. At the end of an interference period, the wireless device can send a trigger signal indicating the start of an interference free interval to request data be sent to the wireless station until the expiration of the duration of the interference free interval. In particular embodiments, the signal sent by the wireless device can include an offset, for example a timing synchronization function (TSF) value, to indicate the end of the interference-free interval, perhaps computed so as allow for some clock drift.
