Spread identity communications architecture
Real routable external addresses may be pooled rather than assigned to nodes and may be dynamically bound to connections by a proxy or gateway device in ways that spread apparent identity of individual nodes across multiple of the external addresses. In general, these spread identity techniques may be employed at one end or the other of a connection, as well as at both ends. In a typical double-ended configuration, the architecture and associated techniques provide “double-blindfolding,” wherein true identities (addresses) of communicating peers are always hidden from each other. In some double-ended configurations, dynamic binding may be employed at a fine level of granularity, for instance allowing individual packets associated with given connection to bear different apparent source addresses and/or different apparent destination addresses. In some single-ended configurations, a spread identity proxy is interposed between an information server and a plurality of requesters. The proxy redirects individual inbound connection requests for information from the information server to distinct addresses of a pool and establishes corresponding network address translations thereby dynamically spreading identity of the information server across multiple distinct addresses of the pool. |

Method and device for determining a PWM signal on which a dither frequency is superimposed in order to control a solenoid valve
A PWM signal on which a dither signal is superimposed is used for adjusting a central position when controlling a solenoid valve. To improve this type of control process in which the amplitude of the dither signal depends on the current of the solenoid valve and thus on the PWM signal, the PWM signal and the dither signal are generated in a computer unit independently of the power regulation process. Forming the signals separately has the advantage of generating a constant amplitude for the dither signal each time a triggering signal is generated for the solenoid valve such that the armature of the solenoid valve can oscillate specifically about the central position and thereof at constant small vibrations. This allows frictional forces to be reliably reduced and the solenoid valve to be switched more rapidly while the load on the main computer is reduced. |

Wide area and local network ID transmission for communication systems
The embodiments utilize OFDM symbols to communicate network IDs. The IDs are encoded into symbols utilizing the network IDs as seeds to scramble respective pilots that are then transmitted by utilizing the symbols.

The single symbol structure for transmitting the network IDs is independent of the number of network ID bits and minimizes frequency offset and Doppler effects. The multiple symbol structure allows a much coarser timing accuracy to be employed at the expense of transmitting additional symbols. Several embodiments employ a search function to find possible network ID candidates from a transmitted symbol and a selection function to find an optimum candidate from a network ID candidate list. |

Communication system with MIMO channel estimation using peak-limited pilot signals
In a collaborative, multiple input, multiple output wireless communication system, a transmitting device transmits a peak-limited pilot signal to a receiving device. The receiving device independently synthesizes the same pilot signal transmitted by the transmitting device. The synthesis process involves precoding the pilot signal and peak limiting the precoded pilot signal. The receiving device receives a signal r that represents the product of (i) a channel matrix H between the transmitting device and the receiving device and (ii) the peak-limited pilot signal yp(n)′ plus noise η, i.e. r=Hyp(n)′+η. The synthesized, peak-limited pilot signal can then be used by a channel estimator to determine an estimated channel matrix Ĥ. Thus, the estimated channel matrix Ĥ represents a closer estimate of the channel matrix H than conventional channel estimation processes and, thus, can provide better corresponding performance than conventional MIMO wireless communication systems. |
