摘要:
A multi-service transport apparatus for integrated transport networks that may have an electrical matrix, termination function means handling signals incoming at said apparatus input, a plurality of termination function means interfacing different layers, and adaptation function means. The termination function means handling incoming signals are implemented in input/output port devices; the termination function means interfacing different layers and said adaptation function means are implemented in adapter devices. The matrix performs exclusively the switching of the incoming signals that are already terminated and adapted by said input/output port devices and by said adapter devices and it is transparent with respect to the signal format. The switch may have a time division multiplexing matrix provided with a number of matrix inputs and a number of matrix outputs; source address generators, connected to matrix outputs of the time division multiplexing matrix.

A scalable N×N single-chip dual-band MIMO RF transceiver module compatible with the IEEE 802.11n standard for WLAN applications is provided. A modular design approach allows a transceiver of substantially any dimension to be created on a single chip that may be easily integrated with other system components. An N×N MIMO transceiver module includes N substantially identical transceiver blocks and a common local oscillator. Each transceiver block includes transmitters and receivers for transmitting and receiving signals in two distinct frequency bands. The transceiver blocks further include one or more local oscillator signal repeaters for receiving one or more local oscillator signals and forwarding the one or more local oscillator signals to subsequent transceiver blocks.

Disclosed is a memory-based switching matrix for cross-connecting the content of a plurality of input flows into the content of a plurality of output flows, the input flows being in the form of frames and said content being Time Division Multiplexed or packet data or whatever, the matrix comprising a number of physical memories for memorizing incoming input flows to be output in a predesigned order. The matrix is characterized in that the number of physical memories comprises a first number of memories having a writing role and a second number of memories having a reading role, with the second number being higher than the first number, and in that the role of each memory changes after at least one clock cycle. The arrangement according to the invention saves a number of physical memories with respect to known arrangements.

An adjustable orthopedic corset to support a user's spinal column includes a rigid frame having a pair of upper, intermediate, and lower connecting slots to which a pair of front and rear straps, wrapped around the user, are connected. A further pair of connecting slots for a pair of pelvic straps, which join at the front of the user via abdominal plates, are envisaged at a lower end of the rigid frame. The pair of front and rear straps are provided by three sliding points for each side of the rigid frame. Each front strap is equipped with a first sliding point located at upper connecting slots. Each rear strap is equipped with an anchoring point located at the intermediate connecting slots, a second sliding point at slots secured to the lower ends of the two front straps, and a third sliding point at the lower connecting slots.
