摘要:
A serializer and a deserializer are disclosed and shown operating singly or as a pair. The invention operates independently from any outside system reference clock. The inventive system provides an internal bit clock that serializes the data when sending and de-serializes the data when receiving. A bit clock or pulse travels with the data word bits to define when a bit is stable. The system uses word boundary bits operating with a bit clock to distinguish different data words, as described in the parent application. The system operates either synchronously or asynchronously with the base computer or other such digital system, including I/O devices. The invention finds use where new data to be sent is strobed into the serializer, but also where a change in the data bit content itself will cause the changed data to be loaded into the serializer and sent bit by bit. The system operates where new data is strobed or loaded by the serializer (not the base computer system) when the last data word has been sent. In this case a signal is generated when the last word has been sent in the serializer that causes new data to be loaded for sending. Half duplex and full duplex configurations as disclosed. Similar, corresponding operations occur at the deserializer.

A bi-directional serializer/deserializer is disclosed using a single bi-directional data line and a single bi-directional clock line. Gated buffers are controlled to operate either sending or receiving data, and a phase locked loop provides a clock to shift data out from a shift register. A reference clock is supplied to the PLL and the PLL generates a synchronous bit clock. The bit clock is sent over the clock line in parallel with the serial data bits, and the PLL bit clock is synchronized to the data bits. The receiving system will use the bit clock to serial load a receiving shift register. When a word is received a word clock is available to inform the receiving system. An embodiment of the system sends data to a receiving system using a clock generated at the sending system. Another embodiment receives data but uses a clock that is sent from the receiving system to the sending system, wherein the sending system uses the received clock to generate a clock to send the data and a synchronous clock that is sent back to the receiving system to load the data from the data line.

A bi-directional serializer/deserializer is disclosed using a single bi-directional data line and a single bi-directional clock line. Gated buffers are controlled to operate either sending or receiving data, and a phase locked loop provides a clock to shift data out from a shift register. A reference clock is supplied to the PLL and the PLL generates a synchronous bit clock. The bit clock is sent over the clock line in parallel with the serial data bits, and the PLL bit clock is synchronized to the data bits. Two data boundary bits are inserted between the word data bits, the boundary data bits are arranged with a logic level transition between the two data boundary bits. Also, at the boundary of the words during the sending of the two boundary data bits, the synchronous bit clock is arranged to have no logic level transition. The receiving system will use the bit clock to serial load the received word and boundary data bits into a shift register. A word boundary is detected by sensing a data bit transition while there is no bit clock.

Described are systems and methods for managing data traffic to a plurality of mobile devices over a wireless network. For each mobile device, a facility is provided that is capable of: (i) assigning a utility function to mathematically represent the value of a plurality of applications running on that mobile device with respect to a factor, (ii) aggregating the plurality of utility functions to generate an aggregated utility function corresponding to that mobile device, and (ii) communicating at least one of the associated aggregate utility function and a bid price based on the associated aggregate utility function over a network. A resource allocation is determined among a plurality of mobile devices based on a bidding process which accounts for the aggregate utility functions, and the data traffic between the mobile devices and the resource is managed using a network traffic shaping element according to the resource allocation.

An implantable access port for use in transferring a fluid transdermally between an external fluid storage or dispensing device and a site within a patient's body is disclosed. The access port includes a base, a bowl-shaped reservoir defined within the base by a smooth surfaced wall, and a septum secured to the base and enclosing the reservoir within the base. The access port also includes a reservoir outlet defined centrally within the reservoir. The bowl-shaped reservoir is defined by a continuous smooth-surfaced curvilinear wall. The reservoir may thus be sized and shaped as a parabola, or may be hemispherical or semi-hemispherical in cross-section. The reservoir outlet is defined at a center point on the bottom of the reservoir wall, may be partially or fully recessed within the bottom of the reservoir wall, and is also defined in the base tangentially with respect to the bottom of the reservoir wall. The access port also has an outlet passageway defined within the base and extending in communication with the reservoir outlet and an external opening defined in the exterior of the base.

An undercoat composition comprises a film-forming synthetic resin and contains a non-volatile acidic aromatic polar organic compound in free acid or salt form, which compound facilitates the removal by a stripping composition of a top coat paint which is subsequently applied over the undercoat. A top coat composition for applying as the outer coating on a substrate comprises a film-forming synthetic resin having functional groups and a curing agent for crosslinking the synthetic resin and contains a non-volatile acidic aromatic polar organic compound in free acid or salt form, which compound facilitates the removal of the cured top coat by a stripping composition from a cured undercoat of similar composition which does not contain the said acidic aromatic polar organic compound.
摘要:
A programmable switch of three or more ports, each port having data lines separate from lines sharing control and addressing. The programmable switch includes internal logic control and electronic modules that accept and deserialize the control and address signals. The logic control directs the data in signals to one or more of the output data lines. Since the data and control and addressing lines are separate, the control may act concurrently with the data to direct the data properly. The sending unit must synchronize such operations to ensure data coherency and proper timing. The data signal path from any input to any or all outputs is designed to have, typically, only a single logic gate or on transistor switch delay.
