The sensor includes at least a detector, first circuitry, and second circuitry. The detector includes a plurality of photosensitive elements organized in first and second arrays. The first circuitry is configured to combine signals from every Mth element of the first array to generate M group signals, and the second circuitry is configured to combine signals from every M′th element of the second array to generate M′ group signals. M and M′ are numbers which are different from each other. Other embodiments are also disclosed.

摘要： An electrical strip of infrared radiating elements which is powered by a battery and rolled up on a wheel and has many advantages over the present device. The first is visibility. It is highly visible at over three miles and the system is a 3/4" strip with LEDs placed every meter and on both sides that is rolled up on a reel. To deploy the marker the strip can be staked or held at one end while the strip is simply unrolled of the reel. The PIRM is self packing and, if packaged to do so, can automatically roll itself up. The PIRM can be operated either by a switch on the reel or remotely, by laser remote control or by a switch on the reel. The flashing pattern is completely programmable. The pattern can be used as a wind direction indicator. The speed it flashes can be used to indicate how hard the wind is blowing or how dangerous the landing zone is.

摘要： A signal processing circuit and processing method are provided for measuring an analog signal from a photo-detector. Generally, the method includes steps of: (i) sampling and storing a characteristic of the signal at a first predetermined time following a reset of the circuit; (ii) sampling the characteristic of the signal at a second predetermined time following a reset or initialization of the circuit; (iii) determining a difference between the stored characteristic of the signal sampled at the first predetermined time and the characteristic of the signal sampled at the second predetermined time; and (iv) converting the determined difference to a digital value and determining a slope of the signal from the digital value and the difference between the first and second predetermined times. Thus, the measurement of the slope is independent of and substantially unaffected by absolute values of the characteristics measured at the first and second predetermined times.

摘要： The present disclosure describes an optical displacement sensor having a dense multi-axis array of photosensitive elements. Generally, the sensor includes a two dimensional array of multiple photosensitive elements. In one embodiment, the array includes multiple linear arrays of photosensitive elements arranged along three or more axes in a space-filling, close-packed multi-axis array. The photosensitive elements are connected to each other in such a way that motion is determinable along each of the axes by measuring differential photocurrents between photosensitive elements along each of the axes. The inventive architecture advantageously increases signal redundancy, and reduces signal drop-out or low signals due to random fluctuations in the incident or absorbed light or in the signals from the photosensitive elements.

摘要： A signal processor and processing method are provided for measuring current received from a photo-detector. Generally, the processor includes a transimpedance amplifier (TIA) to integrate a current received from a photo-detector in the optical navigation system to generate a voltage signal having a slope that is proportional to the received current, and a comparator having a first input coupled to an output of the TIA to receive the voltage signal, and a second, inverting, input coupled to a threshold voltage. The comparator is configured to compare the voltage signal to the threshold voltage and to generate an output pulse having a predetermined voltage and a duration or width that is a function of the received current.

摘要： One embodiment disclosed relates to a method of providing drive signals to an illuminator module having a plurality of channels in a printing application. Binary image data comprising image bits is provided from a data source to the illuminator module. Each image bit is converted to a multi-bit amplitude value within the illuminator module, wherein the conversion of each image bit to the multi-bit amplitude value depends at least on a value of the image bit and which channel is associated with the image bit. Pulse width modulation (PWM) may be applied to the drive signals using programmable transition delays. Apparatus for performing the aforementioned method are also disclosed.
