Title: Method for producing a ceramic unit
Inventor: ANDERSSON MATTS
IPC: A61C5/77
Filed: 1990-02-21
Granted: 1998-08-25
Abstract: A ceramic unit for replacing lost substance or tissue and having a contour transferred from a preparation model or a  replacement  position is  made  of  densely  sintered ceramic material.  The model contour in question or a corresponding  contour  is  transferred  in  a  linearly enlarged state to a part (4) belonging to a press tool (6), whose enlarged contour (2') defines a mould cavity (5)  formed by means of the part in the press tool. Ceramic starting material is applied in the mould cavity and is subjected to compressive force. The unit produced in this way is released or removed and is treated in one or more sintering procedures in which it is subjected to linear shrinkage until the contour defined by the tool part has essentially the same size as the model contour.            It is proposed that Figure 2 accompany the abstract.

Title: Adaptive network routing for power line communications
Inventor: LAPORTE ERIC
IPC: H04L12/403
Filed: 1990-04-26
Granted: 1999-01-19
Abstract: Optimum routing for communications between a central control unit (CCU) and remote units (nodes), such as electricity meters, distributed on an electrical power line is established by broadcasting from the CCU an interrogation signal to be received by the remote units. In response to a receipt of the interrogation signal, each remote unit returns an acknowledgement signal, time multiplexed with the acknowledgement signals of the other remote units, to the CCU which determines which units, if any, are "mute", i.e., have not acknowledged. The CCU then selects remote units in proximity to the mute remote units if it has already a good knowledge of the network or at random otherwise, to function as relays and repeats interrogation of the remote units via the relays. This process is repeated, if necessary, until communication paths between the CCU and all remoteunits are established directly or via relay units, to form maps. Numerous maps developed for the nodes during various time periods having different power line interference characteristics are stored in a data base to be accessed by the CCU to quickly establish an optimum route during subsequent periods having similar lineinterference characteristics.

Title: Multi-position retractable hardtop roof
Inventor: KLEIN GEORGE W
IPC: B60J7/05
Filed: 1990-12-28
Granted: 1995-02-14
Abstract: A multi-position hardtop roof for a vehicle which is retractable between a coupe position enclosing the passenger compartment and a convertible position wherein the roof is stored within the rear deck of the vehicle. The roof is segmented into a front fixed panel incorporating the windshield, an intermediate panel and a rear panel. The intermediate panel of the roof is telescopically retractable onto the rear panel and both movable panels are thereafter retractable into the rear deck of the vehicle. From the coupe position, the intermediate roof segment can be tilted to a second venting position. Further retraction moves the intermediate segment rearwardly onto the rear roof segment to a targa position. Finally, the roof segments may be fully retracted to the convertible position. Two sets of piston/cylinder mechanisms control movement of the intermediate segment and the rear roof segment. The longitudinal retraction and the segmented construction of the roof facilitate retraction even while the vehicle is moving and minimizes the storage space required for the fully retracted roof.

Title: Noise-immune space diversity receiver
Inventor: OKANOUE KAZUHIRO
IPC: H04L1/20
Filed: 1991-04-02
Granted: 1994-12-13
Abstract: In a space diversity receiver, matched fitters and a like number of channel estimators are respectively coupled to diversity antennas to receive sequentially coded symbol sequences. A branch metric calculator receives the outputs of the matched filters and the estimates from the channel estimators to calculate a branch metric of the received sequences for coupling to a maximum likelihood (ML) estimator. The branch metric is obtained by summing branch metric coefficients derived from channel estimates respectively with the output of the matched filters or by summing branch metric coefficients derived from a vector sum of channel estimates with the matched filter outputs. In another embodiment, adaptive channel estimators are provided for deriving channel estimates from received sequences and the output of an ML estimator. First branch metrics are derived from the received sequences and supplied to a branch metric quality estimator in which quality estimates of the channels are derived from the first branch metrics. An evaluation circuit evaluates the first branch metrics according to the quality estimates and produces a second branch metric for coupling to the ML estimator.
