Title: Viterbi decoder with l=2 best decoding paths
Inventor: CZAJA STASH
IPC: H03M13/45
Filed: 1996-06-13
Abstract: This invention teaches a method, and circuits that operate in accordance with the method, for decoding data received from a communications channel.  The method includes the steps of: (a) receiving a modulated communications signal that conveys block encoded data having at least a data field and a syndrome data  field;  and  (b)  determining transition metrics and path metrics for the block encoded data. The step of determining path metrics includes a step of retaining path metrics only for a Maximum-Likelihood (ML) path and for a second best ML path. The method further includes a step of: (c) decoding the block encoded data by performing either a full or a partial traceback operation for both the ML path metrics and also for the second best ML path metrics. In a full traceback there is obtained from the ML path a first plurality of detected bits representing the data field, a second plurality of detected bits from the ML path representing the syndrome data field, a third plurality of detected bits from the second best ML path representing the data field,  and a fourth plurality of detected bits from the second best ML path representing the syndrome data field. A next step (d) determines a syndrome from  the  first  plurality  of  detected bits,  and  then compares the determined syndrome to the second plurality of detected bits. Upon a match a next step (e) outputs the first plurality of detected bits as a received frame of data. If the step of comparing the determined syndrome to the second plurality of detected bits does not indicate a match, the method instead: (f) determines a syndrome from the third plurality of detected bits;  (g)  compares the determined syndrome to the fourth plurality of detected bits and, upon a match, (h) outputs the third plurality of detected bits as a received frame of data.

Title: Adapter for oil well tubings
Inventor: PINHEIRO ELIBERTO EDUARDO
IPC: E21B43/12
Filed: 1996-06-26
Abstract: An adapter for oil well tubings interconnects two tubings in the interior of an oil well. Two types of adapters are provided, one for use when the two tubings are not installed at the same time and the other for use when the tubings are installed simultaneously. The first type has in its interior two bores to connect to the two tubings. The top end of the first bore is threaded to permit its connection to one of the tubings. The second bore has a diameter larger than that of the first to permit the insertion into its interior of the second tubing. The second type of adapter has in its interior two threaded bores to interconnect the two tubings. In both types of oil well tubing adapters, the bottom portion of the adapter has a 180° bend segment which permits communication between the two orifices, thus making intercommunication between the tubings possible. A connection in the bottom part of the adapter permits its interconnection to a tubing conducting the ascending flow of oil coming from the production region, this flow passing into the interior of the tubing adapter by way of orifices existing in the internal part of the connection. These orifices likewise prevent the passage of the mechanical interface to the bottom of the well, the occurrence of which would make it impossible to apply an intermittent production method with a mechanical interface.

Abstract: A lid switch assembly including a lid switch configured to be substantially located within a coin box of a coin operated appliance is described. In one embodiment, the lid switch assembly is configured for use in connection with a coin operated washing machine including a lid rotatably mounted to a washer cover and a coin box mounted to the washer cover adjacent the lid. The lid switch assembly includes a hinge rod secured to the lid and rotatable with the lid. The hinge rod includes an actuating arm configured to be substantially located within the coin box. The lid switch assembly also includes a switch configured to be mounted within the coin box. The switch is electrically connected in series with a power source and the washing machine motor. The switch includes a switch actuator movable from and between a first position and a second position. The switch actuator is biased to be in the second position. The switch actuator is positioned so that when the washing machine lid is closed, the hinge rod actuating arm acts against the switch actuator and holds the switch actuator in a first position. As the washing machine lid is opened, the hinge rod actuating arm rotates so that the switch actuator moves from the first position towards the second position. Once the washing machine lid has been opened a predetermined distance, the hinge rod actuating arm sufficiently rotates so that the switch is in the non-conducting state. Regardless of whether proper coins have been deposited and whether the operator start button is depressed, when the switch is in the non-conducting state, the switch prevents energy from being be supplied to the motor and washing machine operations stop.
