Abstract: A method and apparatus for deriving performance statistics from real time tracking of a sporting event. The method according to the present invention includes a step of obtaining a spatio-temporal trajectory corresponding to the motion of an athlete and based on real time tracking of the athlete. The trajectory is then broken down so that performance information corresponding to the motion of the athlete (such as speed, distance covered, acceleration, etc.) can be derived with respect to time. The information so obtained can be stored in a database or the like for later retrieval or can be used to graphically supplement a video broadcast of a sporting event. The apparatus includes a device for obtaining the trajectory, a computational device for obtaining the performance information based on the obtained trajectory, and a statistical device for compiling the performance information.

Abstract: In addition to aligning a first unit for proper forward link communications in a wireless environment, there is a method of alignment where a reverse link signal is transmitted from the first unit to a second unit, so that the first unit may be positioned based on at least one signal quality parameter measure contained in a forward link signal reply to the reverse link signal. The method enables an installer to verify signal quality in both the forward link and reverse link directions by reviewing indications of received signal strength for both the reverse link and forward link directions on an LED display, so as to position the first unit for achieving acceptable signal strength in both directions.

Abstract: A cache implements bank-by-bank locking to keep critical code from being flushed out of the cache. A register is maintained to rank the banks from the most recently used to the least recently used. Ordinarily, when code needs to be moved into the cache, the least recently used bank is flushed, the code is moved into that bank, and the register is updated to identify that bank as the most recently used. However, if a bank is designated in a bypass vector as being locked, that bank is bypassed in the maintenance of the register and is thus never identified as the bank to be flushed.

Abstract: The location of a mobile unit in the service area of a CDMA wireless communications system is determined by a location probability distribution procedure that is based entirely on analytical results derived from an integrated model of the wireless communications system, its RF environment and attribute measurement. The mobile unit measures and reports attribute values of pilot signal strength of all pilot signals visible to the mobile unit at its present location, whereupon a location probability distribution is computed based on a Bayesian probability algorithm including a set of stored model parameters.

Abstract: The processor includes at least a lower and a higher level non-inclusive cache, and a system bus controller. The system bus controller snoops commands on the system bus, and supplies the snooped commands to each level of cache. Additionally, the system bus controller receives the response to the snooped command from each level of cache, and generates a combined response thereto. When generating responses to the snooped command, each lower level cache supplies its responses to the next higher level cache. Higher level caches generate their responses to the snooped command based in part upon the response of the lower level caches. Also, high level caches determine whether or not the cache address, to which the real address of the snooped command maps, matches the cache address of at least one previous high level cache query.
