摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Multiple Input Multiple Output (MIMO) technology in conjunction with the IEEE 802.11 standard enables simultaneous communication of data packets to or from multiple users in the same frequency. Spatial divisional multiple access (SDMA) is thus provided. In this way, system capacity can be increased to an extent that depends on available antenna resources and the multipath characteristics of the communication channel. Doubling or quadrupling of network throughput can be achieved.

摘要： A Communications system for communicating over low bandwidth or high latency links incorporates a router MR7 configured to route a message to any like-configured router MR8, MR9 linked to it. Communications are implemented at network layer with UDP IP message packets. There are no hello messages. The message format 20 includes routing information but not designated and backup routers, which avoids loss of service from designated router changes and reduces bandwidth requirements. Configured routers MR7 to MR9 have different message formats 20, 40 for communicating with configured routers MR7 to MR9 and with unconfigured routers R1 to R6 respectively, and can link different protocols. A configured router MR7 deletes routes to like-configured routers MR8, MR9 with route metrics not superior to other routes with like destination. It also deletes routes with inferior metrics to related routes in an incoming message, and retains received route information regarding a new route or a route with superior metric. Some routes are not advertised, e.g. loop-back routes, multicast or broadcast routes, experimental destinations, unconfigured or zero-configured addresses, and routes matching a summary route and any user configured routes/networks.
