Abstract: The invention relates to a method in a hardware semaphore lock (L1–LN) intended for a multi-processor system, which semaphore lock (L1–LN) protects a shared resource (R1–RN) in connection with the system in such a way that only a process which has reserved the semaphore lock (L1–LN) and has thus become a holder of the lock, has access to use the resource protected by the lock. The semaphore lock (L1–LN) is reserved by a single read operation of a memory location representing the semaphore lock by the process software. The read operation returns to the process the number of vacant holder positions, i.e. keyholes vacant at the time of the reservation of the lock. The semaphore lock does not require the support of the system for atomic read/write operations.

Abstract: A system and method for providing reference information to a user of a wireless terminal operating within a wireless network. Request identifiers are entered at the wireless terminal to identify desired reference information corresponding to the request. The desired reference information is presented to the user via the wireless terminal if the desired reference information is locally stored at the wireless terminal. If the desired reference information is not locally stored, the request identifier is transmitted from the wireless terminal to a data server, such as a dictionary server, operating within a second network via a gateway bridging the networks, and is presented on the wireless terminal.

Abstract: Plural service providers each provide services to one or more multicast service systems, which forward service sets formed by bundling received services to a respective multicast operator. The service sets are then multicast in IP datacasting bursts, and can be received by a mobile terminal. Each service includes one or more service components, which have different media formats, e.g. audio, video, game, software, chat, offline web page, etc. The service components include content data and service identification data. A service set schedule giving timing information relating to the transmission of the IP datacasting burst and the transmission frequency is created. An IP burst begins with ESG data. The service set schedule may be part of the ESG data or it may be transmitted separately.

Abstract: A method is provided to minimize the protocol stacks needed for a short range wireless access point to rapidly communicate a message to a short range wireless mobile device and display it to the user. The short range wireless access point device stores an Access Point Service Indicator (APSI) message characterizing the service platform offerings. The APSI message has a unique message ID in its header. The user device's transport protocol layer is modified to detect the unique message ID and load it into an APSI message buffer. The transport protocol layer passes the APSI message directly to the application layer, bypassing the middleware protocol layers. The method can be applied to communications between various types of wireless devices to enable rapid communication, such as between two mobile devices, between fixed and mobile devices, between short range devices or between long range devices.

Abstract: A smoke detection device for use in a portable device such as a mobile terminal. The smoke detection device comprises a light emitter and a light detector disposed on different locations on the portable device so that when smoke or an intruding object is presence in the light path of the light emitter outside the device housing, it causes the light emitted by the light emitter to be scattered or reflected. When the light detector senses the scattered or reflected light, it can cause an alarm signal to be produced by the portable device. The emitted light can be in the infrared region so that the detection is independent of the ambient light. Alternatively, the light emitter is operated in a pulsed mode. Additional light emitter and light detectors can be disposed on the portable device for proximity sensing in addition to smoke detection.

Abstract: A method for reducing interference in a MIMO MultiCode MC-CDMA system is disclosed wherein a BLAST algorithm is implemented over one block of correlation reception data yi and estimation channel values H of the correlation reception data yi to generate a group of temporary decision symbols C . One symbol, Cki, is selected having a maximum SNR value from the temporary decision symbols. The temporary decision symbols, C, other than the selected symbol, Cki, are combined with the estimated channel value H to recover a group of temporary interference signals over the selected symbol, Cki. The interference signals are subtracted from the correlation reception signal vector, yi to generate a corrected reception signal vector yi+1, and a more accurate decision symbol Cki+1 is identified from the corrected reception signal vector yi+1 and original estimation channel values. The foregoing steps are repeated for other symbols C{circumflex over (k)}i.

Abstract: A method and apparatus for accelerating program execution in platform-independent systems by eliminating repeated hot spot recognition in virtual machines. Optimization information for programs operable on a target device is stored. It is determined whether stored optimization information exists for a current program available on the target device, and if so, the optimization information associated with the current program is retrieved. The retrieved optimization information is used to identify program code segments earlier identified for optimization processing. Portions of the current program not identified for optimization processing are interpreted via an interpreter, and at substantially the same time, the program code segments identified for optimization processing to native code of the target device are compiled. Using the stored optimization information eliminates the need to analyze the program for program hot spots each time the program is loaded.
