Patent CA-2106936-A1 (CA)
Inventor: YUN JONG-YUN
IPC: G11B20/10
Filed: 1993-09-24
Abstract: A circuit and method for variably adjusting a data detecting level by using a pulse with modulation (PWM) signal. The pulse width modulation (PWM) signal having duty corresponding to a predetermined level control value is generated, and the level of the pulse width modulation (PWM) signal is detected to determine the data detecting level to a level corresponding to the detected level. A read test is performed while the level control value is incremented by a given stage from an initial level control value in in response to a test mode, to determine the level control value less than that generating a data error by one stage to a maximum value. Further, the read test is implemented while the level control value is decremented by a given stage from the initial level control value, to determine the level control value greater than that generating the data errorby one stage to a minimum value. Thus the initial level control value or level control value is obtained by an average value of the maximum and minimum level values. Therefore, the data detecting level adapted for each disk driving apparatus can be adjusted without modifying hardware of each disk driving apparatus, and the data error can be prevented by adaptively adjusting the data detecting level to operating circumstances.

Title: System for Channel Capacity Modulation
Inventor: BETTS WILLIAM L
IPC: H04L5/14
Filed: 1993-09-30
Abstract: A method and apparatus for optimizing parameters selectable by an analog modem for operation on any bandwidth-constrained channel is provided. Through the addition of circuitry for performing an optimization process, the modem is configured for identifying the optimum bandwidth and maximum data rate for use over a selected bandwidth-constrained channel. In the process of optimizing the parameters for operation on the selected bandwidth-constrained channel, a measurement of the signal and noise spectrum present on the selected channel is determined. And from this measurement, the optimum bandwidth, maximum data rate for the transmission of data over the selected bandwidth-constrained channel and a modulus for performing a modulus conversion of the data for transmission are provided. The modem is then trained to operate using these optimized parameters for transmission of the data.

Title: Digital signal processor delay equalization for use in a paging system
Inventor: MARCHETTO ROBERT F
IPC: H04H20/67
Filed: 1993-11-22
Abstract: DIGITAL SIGNAL PROCESSOR DELAY EQUALIZATION FOR USE IN        PAGING SYSTEM                 Abstract of the Disclosure A method and apparatus provide an equalization time delay to synchronize a plurality of paging transmitters in a simulcast paging system. A delay equalization circuit (41) appropriate for use with an analog input signal includes a coder/decoder (CODEC) (50) and a digital signal processor (DSP) (58). An analog input signal is digitized or sampled by an analog-to-digital converter (ADC) in the CODEC, producing corresponding digital values that are input to the DSP. The DSP employs a selected finite impulse filter to interpolate between the sampled digital values from the CODEC to provide enhanced resolution in delaying a signal output that is output. The DSP determines a major sample index and an interpolated filter index to achieve the desired equalization time delay. These variables define two delay intervals that are combined to provide the required equalization time delay. As each sampled digital value is produced, the delayed value is output and converted by a digital-to-analog converter (DAC) 54 in the CODEC to an analog signal having the corresponding required delay. By thus providing the appropriate equalization time delay to thesignal transmitted by each paging transmitter in a simulcast paging system 20, differences in the time required for the analog signal to propagate from a paging terminal to each paging transmitter are compensated, thereby substantially eliminating phase interference in overlap zones of the paging transmitters.

Title: Waveguide holographic telltale display
Inventor: SMITH RONALD T
IPC: G02B27/00
Filed: 1993-12-21
Abstract: A waveguide holographic telltale display for displaying images to a vehicle driver via the vehicle windshield. A light source injects light into the base of a clear inner windshield singlet.  A mirror hologram between the inner and outer singlets confines a majority of the injected light to the inner singlet.  An image hologram between the windshield singlets diffracts light out to the vehicle driver.  A halfwave plate between the image hologram and the inner singlet reduces ghosting and allows the driver to view the images even through polarized sunglasses.   IR light is blocked by a tinted outer singlet or a holographic solar coating.   The display does not suffer from ambient turn from the sun, and the light source is hidden away from the vehicle dash.

Title: Process for imparting a localized fine grain microstructure to selected surfaces in aluminum alloys
Inventor: MAHONEY MURRAY W
IPC: C22F1/04
Filed: 1995-02-03
Abstract: A process of cold working followed by rapid recrystallization imparts a localized fine grain morphology in and around surfaces of fastener holes and edges in aluminum materials. A peening tool that may be employed for surface cold working includes a hollow housing with openings for retaining a plurality of ball peens that may be driven by rotating cams or an oscillating tapered piston operating within the housing to force the ball peens to impact the surfaces of an edge, cavity, or fastener hole to which the tool is applied. The tool may be shaped to accommodate straight bored, counter bored, countersunk, and/or edge surfaces and may be applied manually or automatically for cold working over substantially the entire surface area of the edge or cavity. The peening tool effects localized cold working to a predetermined and controlled depth to break up the existing large pancake-shaped grain structure in the surface of the aluminum alloy. After the surfaces have been cold worked, rapid heating recrystallizes the cold worked surfaces to attain a localized fine grain corrosion and fatigue resistant microstructure. The process provides the benefits of exfoliation corrosion resistance and improved fatigue life by using microstructural control rather than chemical coatings that may be harmful to the environment. The process produces a stable microstructure that allows subsequent use of other treatments to act in parallel as multiple barriers to corrosion.

Abstract: Sprayable fireproofing compositions for structural members such as steel columns are provided, as well as a method of applying multiple coatings thereof. The compositions comprise a Portland cement-based material, stucco, a high density aggregate and an accelerator. The compositions eliminate the long setting times typical of Portland cement-based materials, and improve the hangability thereof. The product is produced by dry blending a mixture of Portland cement, a high density aggreagte, stucco (calcium sulfate hemi-hydrate) and optionally, a stucco set retarder and shredded polystyrene aggregate. Upon the addition of water, sprayable slurries are formed which can be pumped to the point of application. An accelerator is added in close proximity to the point of injection. The slurries adhere to the structural member in the slurried state and after setting to provide excellent fire and heat protection. Because of the relative quick setting time of the slurry upon spray application, multiple coatings can be applied within the same working day.
