摘要： A window wiper control system provides accurate regulation and/or profiling of wiper speed. A desired interval corresponding with the preselected speed or speed profile is stored; a reference signal is provided to indicate a reference position of the wiper and is used to measure the actual interval of a wiper stroke or cycle. The actual interval is compared with the desired interval and an appropriate adjustment is made in a pulse-width modulation signal for effecting a desired speed and interval. The pulse-width modulation signal preferably has a relatively-low repetition rate. The wiper speed may be profiled to include acceleration and deceleration, and the intervals of acceleration and deceleration may be lengthened substantially to provide an apparent dwell.

摘要： The invention is a moisture sensor which includes an emitter (18) to emit pulses of radiant energy toward the inside surface (14) of a window (12) at an incident angle (9). The radiant energy is refracted into the window (12) at the air-inside window surface (14) and reflected off the air-outside window surface (16) back through the window (12). The radiant energy is then detected by a detector (20) at a reflection angle (ϑ′) equal to the incident angle (ϑ). A support (22) spaces the emitter (18) and detector (20) a distance D betveen the intersection (I) of the axis (A) of the emitter (18) with the inside window surface (14) and the intersection (E) of the axis (B) oi the detector (20) with the inside window surface (14) which is determined by the formula:

D = 2 T cos ϑ(n² - cos² ϑ)⁻ 1/2

The detector (20) includes a collimator (36) to prevent non-parallel radiant energy from entering the detector (20) and an optical filter (40) to filter out radiant energy wavelengths below a predetermined wavelength in order to detect the emitted radiant energy.

摘要： A system for detecting the presence of rain droplets on a windshield (17) employs a source of light, such as an LED (11), and a photodetector (12) installed on the dashboard (13) of a vehicle. The LED (11) and the photodiode (12) are arranged with respect to one another such that light from the LED (11) cannot reflect directly off the windshield into the photodiode (12). Only when the light from the LED is backscattered by an environmental condition, such as the raindrops (25) on the exterior of the windshield (17), the condensation of moisture on the interior of the windshield (17), or the presence of smoke in the cabin, will the photodiode (12) receive the light from the LED (11). Each of these environmental conditions has a predeterminable characteristic signature which permits the processing of data to detect same. An ambient light signal is subtracted from the combination of the rain and ambient light signals by pulsed operation of the LED (11) and subtracting the ambient light signal, which is detected when the LED (11) is dark, from the combined LED (11) and ambient light signal which is present when the LED (11) is illuminated.

摘要： An optoelectronic sensor (1) for detecting foreign bodies, in particular raindrops on a windshield, has an outer (2) and an inner housing part, as well as a fastening device (4) glued to the pane (5). Guided in the outer housing part (2) are fastening means that consist for example of two slides (6) that may engage the fastening device (4) for fastening the sensor (1) to the pane (5). Inside the sensor (1), the inner housing part that carries the optoelectronic elements of the sensor (1) is biassed towards the pane (5) by the force of springs resting against the outer housing part (2) in order to establish an optical coupling with the pane.

摘要： A wiper speed control system for an automotive wiper controls the operational speed of a wiper in accordance with rain conditions. The control system includes a rain sensor (30) detecting rain conditions to produce . an analog signal having an amplitude depending upon the detected rain conditions. The analog sensor signal is converted into a digital pulse signal by a converter (12) for application to a digital circuit system. A control signal is produced by digitally processing the pulse signal. The control signal is applied to a wiper driver circuit to adjust the operational speed or timing in accordance with the control signal.
