Title: Vehicle rotational-angle calculating apparatus
Inventor: IWATA EIJI
IPC: G01C21/28
Filed: 1995-06-29
Granted: 1999-12-28
Abstract: A first sensor outputs a signal representing an angular rate of a vehicle body.  A second sensor outputs a signal representing a direction of the vehicle body.  The output signal of the first sensor is integrated to generate a signal representing a tentative rotational angle of the vehicle body.  First data pieces are generated which represent temporally spaced samples of the output signal of the second sensor respectively.  Second data pieces are generated which represent temporally spaced samples of the tentative rotational angle signal respectively.  Two first data pieces are selected from among the first data pieces.  Calculation is given of a time interval between the occurrence moments of the selected two first data pieces.  Two second data pieces are selected from among the second data pieces. Calculation is given of a direction difference between directions represented by the selected two first data pieces. Calculation is given of a rotational-angle difference between tentative rotational angles represented by the selected two second data pieces. An amount of offset in the output signal of the first sensor is calculated in response to the calculated time interval and the calculated rotational-angle difference in cases where the calculated direction difference is equal to or smaller than a predetermined direction difference. The output signal of the first sensor is corrected into an offset-free signal in response to the calculated offset amount. The offset-free signal is integrated to generate a signal representing a final rotational angle of the vehicle body.

Abstract: An improved roofing system is presented comprising a built-up roof (BUR) assembly or modified roof membrane assembly (MRM) which is adhered to gypsum, concrete or composite sheets or panels which have been loose-laid over a roof substrate. This allows the BUR or MRM assemblies to conduct heat to or receive heat from the thermal mass of the loose laid mass-weighted sheets immediately below the BUR or MRM assemblies. The gypsum panels, preformed concrete panels, poured-in- place concrete or composite mass-weighted construction panels which are placed between the BUR or MRM assemblies and the roof substrate causes more gradual changes in temperature between the roof assembly and the roof substrate. Because the BUR or MRM assemblies, which are attached to the loose laid gypsum or the like panels, can move independently of the insulated roof substrate panels with the expansion and contraction concomitant thermal cycling, wrinkles and tears previously associated with the joint lines of the roof substrate panels are practically eliminated. Additionally, the weighted roof assembly of the invention aids in wind uplift protection by providing a floating, moveable mass under the BUR or MRM assemblies by distributing wind uplift shock away from the perimeter edge of the roof and into the interior thereof.

Abstract: A digital receiver (10) for receiving an RF signal has a conventional RF to intermediate frequency (IF) converter (14). The IF sign al however, is amplified with a limit on its amplitude (20). In addition, a Re ceive Signal Strength Intensity (RSSI) signal is generat ed (28). The RSSI signal contains the envelope information of the modulated IF signal . The IF amplitude limited signal containing phase info rmation is then digitized and a complex baseband signal is produced (68). The compl ex baseband signal is then combined with the RSSI signal to restore the amplitude information of the modulated IF signal in the complex baseband signal. The restored complex baseband signal c an be equalized with a conventional equalizer (70) to remove intersymbol interfere nce. A conventional symbol detector (80) detects the sy mbol in this signal stream.

Abstract: A method and apparatus are disclosed for performing data compression on raw uncompressed data. The method develops a semi-adaptive modeler that sub-divides the length of an input data file into blocks of fixed size. The blocks are then sub-divided into sub-blocks in which the frequencies of the symbols are mapped to occupy the whole frequency space. The modeler is then used to develop a reduced complexity implementation of arithmetic coding, whereby, the time consuming divide operation used in computing the symbols true probabilities is replaced by a simple shift operation. The reduced complexity arithmetic coder is referred to as approximate arithmetic coder. The modeler and the approximate arithmetic coder are then used in a multi-step data compression system that employs a ZL coder. The multi-step method results in high efficiency data compression systems that are ideal for real time operations and are better suited for network communications or data storage systems. The method overcomes many of the difficulties found in the prior art and generally achieves better compression ratios.

Abstract: The method and apparatus of the present invention improve the immunity to interference of a radio receiver. The power level of a received signal is detected. If the power level meets or exceeds a predetermined power threshold, the low noise amplifier (703) is by-passed (730), thus increasing the intercept point of the receiver components.  Alternative embodiments include the use of an RF power detector (105) to control the front-end gain (110) as a function of jammer power. In lieu of a switchable RF gain block (730), several methods of continuous gain control are proposed. Continuous gain control allows the interference suppression and sensitivity of the receiver to be adjusted at lower signal levels than the switchable gain block. A method of the present invention adjusts the input gain by a predetermined amount (1601). The receiver processing measures the gain change in the IF  signal power (1605). If the change is less than the predetermined amount (1610), the CDMA signal and jammers are below the noise floor and, therefore, the gain is increased (1615). If the IF signal power change is greater than the predetermined amount, the interference is evident and the gain is reduced to reduce the intermodulation products (1620). This process is used until the receiver is operating at the best compromise between interference and noise figure.
