Title: Method for communicating block coded digital data with associated synchronization/control data
Inventor: HUANG ZHENG
IPC: H04L27/18
Filed: 1995-01-18
Granted: 1999-12-07
Abstract: Block coded digital data is communicated with associated overhead data in a data stream having a succession of coded blocks. Each block contains N symbols wherein M of the symbols comprise information to be transmitted and the remaining N-M of the symbols comprise error correcting data. The ratio M/N comprises a first information rate. The coded blocks in the data stream are divided into a succession of frames, each comprising F of the coded blocks. A frame overhead symbol is added for each of the frames, to provide data necessary for a receiver function such as synchronization. The addition of the frame overhead symbols effectively lowers the first information rate to a second information rate M'/N', where M/N = (M' + b)/(N' + b) and b is an integer chosen to provide the second information rate at a desired value. N is less than 2n + 1, where n is the number of bits in each of the symbols. The number of coded blocks F in each frame is determined from the relationship F = M'P/(N-M)b.      P is the smallest value integer that will render F an integer, and is also the number of overhead symbols added per frame. A plurality of X of the frames are formed into a superframe containing FX coded blocks and PX frame overhead symbols. X is chosen to provide enough n-bit frame overhead symbols to implement the desired receiver function.

Abstract: A method of testing the accuracy of results obtained from an automatic viscometer is described.   Firstly, provide an automatic viscometer having at least two capillary tube test sections,  each of a distinct uniform diameter.   Secondly, calibrate the automatic viscometer by allowing a Newtonian fluid of known viscosity to flow through each of the capillary tube test sections and recording the time duration of the flow of the Newtonian fluid through each of the capillary tube test sections.  Thirdly, calculate a viscosity constant for each capillary tube test section by dividing the known viscosity by the recorded flow time.  Fourthly, send a test sample through each of the capillary tube test sections and record the time duration of the flow of the test sample through each of the capillary tube test sections.  Fifthly, calculate values for the viscosity of the test sample based upon the times recorded and the known viscosity constant for each of the at least two capillary tube test sections.  Sixthly, compare the viscosity measurement derived from each of at least two capillary tube test sections. A difference in viscosity measurement exceeding a predetermined limit  indicating that the measurement  is suspect and the accuracy of the automatic viscometer must be checked  as  the  test  sample  is  exhibiting  non-newtonian behaviour.

Abstract: In an external steel sleeve for reinforcing or for providing a seal to prevent leakage in a pipe, the sleeve consists of steel plate material that is shaped and sized to encircle a portion of the length of the pipe. The top and bottom halves of the sleeve each consist of steel shaped plate, and the bottom half in addition has connector plates welded on either side. The sleeve may be installed while the carrier pipe is under operating pressure and temperature. Following cleaning of the pipe and sleeve surfaces, if necessary, including cleaning of any external anomalies on the section of pipe to be reinforced, an epoxy filler material is applied to the pipe over the area to be covered by the sleeve. The top and bottom halves of the sleeve are then placed around the pipe and initially tightened using hydraulic jacking devices. The sleeve halves are then heated uniformly to a predetermined temperature and are maintained at that temperature while welding the connector plates, which are located 180 degrees to each other, to the top half of the sleeve. Upon allowing the sleeve to cool, the sleeve shrinks, thus applying compressive forces onto the pipe. The epoxy acts both as a filler agent and sealant, filling all voids between the pipe and the sleeve. The pipe and sleeve therefore act as one unit, expanding and contracting with fluctuations in the pipe's pressure and temperature. The sleeve prevents the anomaly from rupturing and prevents product leakage should corrosion eat through the pipe wall from within.

Abstract: A remote control system for a vehicle includes a controller for learning a unique code of a remote transmitter to define a learned remote transmitter capable of causing performance of a function associated with the vehicle, for example. The controller performs remote transmitter verification to generate an indication relating to whether a new uniquely coded remote transmitter has been learned by the controller. The remote control system is advantageously used, in one embodiment, for a vehicle security system. Transmitter verification may also be incorporated in a remote keyless entry system, remote engine starting system, and a door access system, for example. In one embodiment, the remote transmitter verification is based upon the controller being recently entered into the remote transmitter learning mode. According to another embodiment, the remote transmitter verification is based upon a number of learned remote transmitters, a change in that number, or a change in a learned code of a remote transmitter. The indication may be provided at the vehicle or remote therefrom by any of a light, a visual display, a vibration transducer, a speech message generator, and an audible signal generator, for example. The indication may be activated in response to an input or condition at the vehicle or remote therefrom. For example, the number of learned remote transmitters may be indicated by operating a valet switch of the security system in a predetermined pattern.
