Abstract: Texture mapping includes (i) calculating the weighted average of the colors of two texels near a particular pixel, (ii) determining a fractional portion of a texture coordinate of the pixel, and (iii) retrieval of a pair of complementary coefficients from a table of pairs of predetermined, complementary coefficients according to the fractional portion of the coordinate of the pixel. Each of the complementary coefficients corresponds to the relative distance between the pixel and each of the two texels as represented by the fractional portion of the first coordinate of the pixel in the coordinate space of the texture image since each texel has whole, integer coordinates in the coordinate space of the texture image. Each coefficient of the pair of complementary coefficients is used to weight a respective one of the colors of the two texels and the weighted colors are summed to produce a weighted average color of the two texels. A weighted average of the colors of the other two of the four nearest texels is calculated in the same manner. The pair of complementary coefficients are partitioned values in a single data word and are therefore loaded into the processor which performs the calculate the weighted average only once to weight two separate colors. The precision and data format of each coefficient of the table are the same as the precision and data format of each component of each pixel of the rendered graphical image. Accordingly, the processing environment remains unchanged while a computer processor alternately interpolates a texel color and combines the interpolated texel color with the color of the pixel.

Abstract: A spray pistol for a high pressure cleaning apparatus has a housing (2) with a fluid inlet pipe (14) that can rotate about the longitudinal axis. At its free end is a union (25) for a detachable hose, the two being connected by rotary action. Between the housing and the pipe is something (28) which can selectively prevent the pipe from rotating or let it rotate freely. The union is outside the housing and is threaded. The pipe is plugged into the housing, its nipple (15) with sealing ring fitting inside a sleeve (11). The axial positioning of the pipe uses a sliding catch (22,23) mating with a shoulder (17,18) on the pipe. The catch is U-shaped, mounted transversely to the longitudinal axis and when pushed in holds the pipe between its arms.

Abstract: An apparatus and method for the tensionless unwinding of a gossamer web of
material from a bobbin uses a servo control system connected between the servomotors
of a web handling apparatus and a bobbin unwinder for controlling the unwinding speed
of the bobbin unwinder in relation to the take-up speed of the web handling apparatus.
A pulsed infrared sensor is used to sense the web position in a loop between the
unwinder and the web handling apparatus and supply a feedback signal to the servo
control system for maintaining the web in a substantially untensioned state. A flow of
air is impinged upon the web adjacent the sensor to prevent unwanted web movement
due to ambient air currents and other transitory forces on the web.

Abstract: A vehicle braking system can, for example when the
performance of a booster has deteriorated, reduce a brake pedal
depressing force required to obtain a sufficient braking force
and thereby lighten the burden on the driver. A booster (2)
and a master cylinder (3) generate a brake fluid pressure in
correspondence with an operation of a brake pedal (1). Wheel
cylinders (4, 5) connected to the master cylinder (3) generate
wheel braking forces in wheels of the vehicle. It is
determined if a vehicle braking state corresponds to a state of
operation of the brake pedal (1), and when it is determined
that the vehicle braking state does not correspond to the brake
pedal operation, brake fluid pressure in the wheel cylinders
(4, 5) is increased with a pump (10). In this way, it is
possible to obtain a predetermined braking force corresponding
to the brake pedal operation at all times.

Abstract: A method for detecting the status of the toner in a laser printer uses a photosensor. The method includes the steps of sampling a signal generated from the photosensor, during a specified time, increasing or decreasing the value of a counter in accordance with an integral algorithm, and comparing the resultant counter value with a reference value, and displaying the status of the toner in the printer on a display device, depending on a result of such comparison. This method can accommodate relatively inexpensive photosensors. As the noise ridden signal generated by such a photosensor is effectively filtered, this method is advantageous in cost and reliability.

Abstract: The present invention discloses a method and
apparatus for monitoring a read channel in a disk drive
system and calibrating the disk drive system. A
comparator is provided to detect the data samples that
fall within a pre-programmed distribution window from a
number of sectors in each zone of a disk. The output of
a comparator is digitized and sent to a logic block to
qualify the valid samples. A relative counter or
histogram of the detected data samples is obtained. The
valid sample count is fed to a n-bit counter that can be
accessed via a serial port. The channel parameters can
be adjusted based upon a relative figure of merit read
off the serial port that reflects the distribution of the
samples with respect to the target value after processing
a statistically valid number of samples. After the
initial calibration, the invention can be switched to
count the number of invalid samples that fall outside the
distribution window. Based upon the invalid sample
count, the invention performs a fine tuning of the read
channel system so that the invalid sample count decreases
and reaches an acceptable value. The invention can be
fully self-contained on chip if desired, and requires no
more than the already existing serial port interface
hardware, and very simple additional software.

Abstract: The invention relates to a method for processing information in a wireless local
loop (WLL) terminal and a WLL terminal. According to the present invention, a
WLL terminal comprises a display device, and character-based information, first
data, is converted to second data for displaying it on the display. Said first data is
advantageously converted in such a manner that a bitmap (222) is first formed on
the basis of the character-based first data and then a line code (223) is formed on
the basis of said bitmap. The line code is transferred (224, 225) by means of known
facsimile transmission technology to a fax machine serving as a display device and
displayed by the fax machine (226). The invention can be applied in wireless local
loops to implement services that use information in character format. Such services
include the short message service and display of caller data, for example.
