Interference in ultrasound imaging when used in connection with high intensity focused ultrasound (HIFU) is avoided by employing a synchronization signal to control the HIFU signal. Unless the timing of the HIFU transducer is controlled, its output will substantially overwhelm the signal produced by ultrasound imaging system and obscure the image it produces. The synchronization signal employed to control the HIFU transducer is obtained without requiring modification of the ultrasound imaging system. Signals corresponding to scattered ultrasound imaging waves are collected using either the HIFU transducer or a dedicated receiver. A synchronization processor manipulates the scattered ultrasound imaging signals to achieve the synchronization signal, which is then used to control the HIFU bursts so as to substantially reduce or eliminate HIFU interference in the ultrasound image. The synchronization processor can alternatively be implemented using a computing device or an application-specific circuit.

A surface rewinding machine for the production of rolls of wound web material is described. The machine comprises: a winding cradle (1, 3, 5) for winding the web material and sequentially forming rolls (R) of wound web material; an insertion device (25) for inserting sequentially, into said winding cradle, winding spindles (M1; M) on which the rolls are formed; an insertion path for the spindles inside the winding cradle. A suction system (51) which follows the spindles along at least one portion of the insertion path so as to produce a vacuum inside the spindles is also envisaged.

A unified and flexible signaling method and radio interface accommodate different multiple access schemes, e.g, FDMA, TDMA, CDMA, OFCDM, and IFDMA. Each user data unit is associated with one of several different multiple access techniques that defines how multiple users access communication resources. Each user data unit is processed into discrete samples, where the discrete samples for each user data unit are assigned to one or more respective discrete signal blocks. Discrete samples associated with different multiple access techniques are processed and grouped together into a time slot or packet for transmission over a communication channel.

Apparatus, system and method for synchronizing one or more clocks across a communication link. A slave clock may be synchronized to a master clock by means of a synchronization signal sent from the master to the slave clock side of the link. The synchronization signal may be an expected signal pattern sent at intervals expected by the slave side. The slave clock may correlate received signals with a representation of the expected synchronization signal to produce a correlation sample sequence at a first sample rate which is related as n times the slave clock rate. The synchronization signal receipt time indicated by the correlation sample sequence may be refined by interpolating the correlation sample sequence around a best correlation sample to locate a best interpolation at an interpolation resolution smaller than the sample resolution. The best interpolation may in turn be further refined by estimating between interpolator outputs adjacent to the best interpolation output. The synchronization signal receipt time thus determined is compared to the expected time based upon the slave clock, which is adjusted until the times match. After initialization, all slave clock errors are preferably accumulated to prevent long-term slip between the slave and master clocks. Formerly independent master and slave clocks synchronized across the communication link constitute a noncommon clock which may be compared on each side of the link to secondary independent clocks, and the secondary independent clocks may then be separately synchronized by adjusting one to have the same difference from its local noncommon clock as the secondary clock on the other side of the link has from its local noncommon clock.

A music editing apparatus is provided that uses so-called time line meta data that describe a beat and melody structure of a song to automatically accomplishes an automatic DJ remix play with a low load. The apparatus also includes a synchronous reproduction controlling section which sends a master beat to the remix processing section and reproduces a plurality of songs corresponding to a remix process which the remix processing section designates corresponding to a remix pattern and the meta data and a mixing section which mixes the songs reproduced by the synchronous reproduction controlling section. The synchronous reproduction controlling section also includes a phase comparator which compares a phase of a beat synchronous signal generated from the meta data supplied from the remix processing section with that of the master beat signal; an integrating circuit which integrates a phase compared output of the phase comparator; and a correcting section which corrects a tempo based on an integrated output of the integrating circuit.

An in-vivo sensing device having multiple imagers controlled by a single processor and a method for communicating between the processor and the imagers. The processor and imagers are connected via common data and control busses, instead of by direct separate conducting lines thereby reducing the number of pins on the processor and the corresponding number of conducting lines.

A master wireless module transmits a beacon signal to a client wireless module in the same cycle as a game processing cycle. Each of the master wireless module and the client wireless module outputs an interrupt signal when a transmission time of the beacon signal arrives. A game processing section of each of the master wireless module and the client wireless module adjusts a V counter based on the interrupt signal. Therefore, it becomes possible to easily synchronize, when a multiplayer gameplay is performed using a plurality of game apparatuses capable of performing wireless communication with each other, times at which the plurality of game apparatuses execute predetermined processes.

A apparatus and method are disclosed for generating one or more clock signals. A clock signal is generated based on pattern signals and a reference clock signal. When the reference clock signal transitions high, the state of a first pattern signal is output, and when the reference clock signal transitions low, the state of a second pattern signal is output. Successive states of the first and second pattern signals, selected according to the reference clock signal, provide the generated clock signal.

The degree of accuracy a machine tool or the like is moved along a given path is determined by a unique preferably laser beam directing measuring system directing simultaneously or in sequence a laser beam parallel to the orthogonal axes of the two or three dimensional space in which the spindle or other object is to be moved in a path which can diverge appreciably in directions other than the directions of these axes. The beam directing means includes means which provides a measure of the actual positions the object has at various sampling times relative to the axis along which the beam is directed. This actual path position data is compared to the desired path position data used to program the object moving machine to determine the path position error at the sampling times involved.

A library of a PC is easily synchronized with recorded contents of a disc loaded into a recording and reproducing apparatus (PD). The PC has a dynamic group and a database. Contents of the dynamic group are, dynamically changed. The dynamic group is correlated with the ID of the disc on which the contents of the dynamic group have been recorded. When the CP and the PD are connected, the ID of the disc loaded into the PD is read. The database is referenced for the ID of the disc. When there is a corresponding dynamic group, the dynamic group is compared with the recorded contents of the disc. Contents that exist in the dynamic group and that do not exist on the disc are checked out to the disc. In contrast, contents that exist on the disc and that do not exist in the dynamic group are checked in to the PC. In addition, the reproduction order of contents of the dynamic group is reflected to contents of the disc. The user can synchronize the recorded contents of the disc with the library of the PC only by connecting the PC and the PD.

An operating system in a virtual environment can obtain the current time of the processor that the OS is utilizing through a method for synchronizing timers on multiple processors with a standard reference time, such as the Coordinated Universal Time (UTC). A hypervisor controlling the processors obtains a number of synchronization values that, together with a local timer counter value, are utilized by the guest operating system to determine the physical processor time.
