Patent EP-0297375-A2 (EP)
Inventor: FETTWEIS GERHARD PAUL
IPC: H03M13/23
Filed: 1988-06-18
Abstract: To implement the Viterbi algorithm (Viterbi decoder) for very high data decoding rates, the basic trellis diagram (original trellis diagram) of the Markov process is considered over a relatively long period. M transitions of the original trellis diagram are in each case combined to form a multi-step transition (multi-step trellis diagram; Figure 1). 
<??>The number of transition branches, which increases exponentially with M during this process, is reduced to a lesser number by utilising fundamental characteristics of the original trellis diagram forming the basis of the multi-step transitions. Independently of multi-step transition to multi-step transition, non-optimal transition branches are eliminated by this means. This allows Viterbi decoders to be built for very high data rates because more time is available for executing the computing operations on several arithmetic units than the maximum time permitted for executing similar (identical) operations when the Viterbi algorithm is implemented on the basis of the one-step transition of the original trellis diagram.

Abstract: The device, for use in particular with compressed air braking systems, is provided with a switching valve (41), by means of which an air drier (12) can be switched from its normal operation of drying compressed air to a regeneration mode for dehumidifying the drying agent, the air drier (12) being connected to a regeneration air accumulator (18). To give reliable switching of the air drier (12) for multiple regeneration of the drying agent, which causes a major decrease in dew point, the switching valve (41) is connected to the outlet (14) of the air drier (12), and is switched when upper and lower pressure threshold values are attained in the regeneration air accumulator (18). A locking device (38, 39) blocks the switching of the air drier (12) independently of the prevailing pressure in the regeneration air accumulator (18), as long as the loading pressure of the compressed air system has not been attained and a pressure regulator (22) monitoring this loading pressure is in circuit. <IMAGE>

Abstract: Elevator system with multiple cars ( 1-4 ) and a group controller ( 32 ) having signal processing means ( CPU ) controlling car dispatching from the lobby ( L ). During peak conditions (up-peak, down-peak and noontime), each car is dispatched and assigned to hall call floors having a large predicted number of passengers waiting on priority basis, resulting in queue length and waiting time at the lobby and upper floors being decreased, and system handling capacity increased. Estimations of future traffic flow levels for the floors for five minute intervals are made using traffic levels measured during the past few time intervals on that day as real time predictors, using a linear exponential smoothing model, and traffic levels measured during similar time intervals on previous similar days as historic traffic predictors, using a single exponential smoothing model. Combined prediction is used to assign hall calls to cars on priority basis for those floors having predicted high level of passenger traffic to limit maximum waiting time and car load. Noontime priority scheme is based on multiple queue sizes and percentages of maximum waiting time limits. Different waiting time limits can be used for lobby and above lobby up and down hall calls with automatic adjustment. During up-peak the lobby is given high priority. The lobby queue is predicted using passenger arrival rates and expected car arrival times. Down-peak operation uses multiple queue levels and per­centages of waiting time limits, with estimated queues based on passenger arrival using car-to-hall-call travel time.

Abstract: A method is disclosed for notifying both the source and intended recipient of a classified electronic message transmitted via a computer network of a delivery restriction imposed by an insufficient classification level at the recipient's system. A required classification level is transmitted by the source of a classified electronic message in association with each classified electronic message and an indication of each classified electronic message is stored in an output log at the source system. Prior to permitting delivery of a classified electronic message, the required classification level is then compared to the classification level of the intended recipient. Delivery of a classified electronic message is automatically restricted in response to an insufficient classification level at the recipient's system and a status message is then transmitted to either or both the source and the intended recipient of the classified electronic message. The recipient may be automatically prompted to attempt to obtain a classification upgrade or forward the message to an alternate recipient in response to such restriction. Additionally, the method permits an undelivered message to be destroyed by the source, the recipient, or the system in response to the failure of delivery.
