摘要： PURPOSE: To generate a cursor control signal without using a shaft encoder by using the patterns of random size and random form on a ball by means of combining them with an optical array. CONSTITUTION: The ball 60 has the random marks in a color forming a contrast with a background and it becomes the ball of the random spots. A ball cage 40 contains at least one LED light source 200 and light is radiated on the ball 60. A part of light emitted on the ball and is diffused is reflected through an array 220 to an optical element 225. A part of an image on a face on which the ball is illuminated is formed on the array 220. Here, diffused light energy quantity reaching the detector array 220 can be made largest and desired light transmission performance can be obtained with a diffracted optical element. A signal generated by the array 220 converts the shift of the ball into X and Y components on the shift of the cursor in a video display part in a logic circuit.

摘要： An image sensor (102) which can output only desired portions of an image. Thus, the image is essentially cropped at the time it is produced, eliminating the generation of data from the image sensor (102) corresponding to undesired portions of the data. This reduces the storage requirements for data being digitally processed, reducing or eliminating the need for a frame buffer memory. In a preferred embodiment, a single silicon chip (100) including a CCD array (102) includes a number of registers (112) which can be programmed for each frame to indicate which lines should be read out. Within each line, the chip (100) can be controlled by timing pulses to quickly read out data before or after the desired cropped portion of the image, with the quickly read data simply being discarded. The actual data desired can then be read out at a slower clock rate to allow processing on the fly.
摘要翻译：图像传感器（102），其仅能够输出图像的期望部分。因此，在生成图像时基本上裁剪图像，消除了与图像传感器（102）相对应的不期望部分的数据的生成。这减少了数字处理数据的存储要求，减少或消除了对帧缓冲存储器的需要。在优选实施例中，包括CCD阵列（102）的单个硅芯片（100）包括多个寄存器（112），其可以针对每个帧进行编程以指示应该读出哪些行。在每一行内，可以通过定时脉冲来控制芯片（100），以在图像的期望的裁剪部分之前或之后快速读出数据，同时快速读取的数据被简单地丢弃。然后可以以较慢的时钟速率读出所需的实际数据，以允许即时处理。

摘要： An improved flexible substrate for a touchpad (10), with the flexible substrate (10) having conductive ink for forming a sensor array (14). A printed circuit board (26) is also used, but only for the components (16, 18 and 20) which need to connect to the array, and not the array, thus giving a smaller printed circuit board. The printed circuit board (26) can have the components compactly mounted on it taking advantage of the close spacing available in PC board technology. The PC board itself has wider spacing on its contacts at its outer edges, allowing it to be attached by conductive glue to the flexible substrate.

摘要： A low cost camera (32) by implementing the major functions in host software is provided. This is accomplished by sending raw, digitized data from the camera (32) directly to the host (36). The increased volume of raw data is handled by either an improved compression/decompression scheme using lossless compression, using lossy compression or using a shared bus (30) with higher bandwidth. By moving such functions a color processing and scaling to the host (36), the pixel correction can also be moved to the host (36). This in turn allows the elimination of the frame buffer memory from the camera. Finally, the camera (32) can use a low cost lens by implementing vignetting, distortion, gamma or aliasing correction with a correction value stored in a register (34) of the camera for later access by the host (36) to perform corrections.

摘要： The present invention provides a touch pad (10) which can detect a simple stylus using a change capacitance. The touch pad (10) is made flexible, so that the stylus pressure compresses an insulating layer between a conductive reference layer and matrix of conductive traces. The compression causes a change in capacitance due to either the two capacitive conductive surfaces being closer to each other, or a variation of the dielectric value of the insulating layer due to the explosion of air in air gaps.

摘要： A positional locating method and apparatus (10) for measuring distances by accurately determining the transit time of ultrasonic wave bursts (22) between two or more points is disclosed. Timer clocks (60), (62), (64) and (66) are started when each of the bursts (22) is triggered to be emitted from a transmission point (14), and are stopped when a highly defined point (56) in the burst (22) is received at a corresponding receiving point (32), (34), (36) and (38). The highly defined point (56) is determined by first analyzing the burst (22) to identify a particular cycle (54) within the burst (22). That particular cycle (54) is then analyzed to detect the specific point (56) within the cycle (54). Use of multiple transmitters (9312), (9314) and (9316) or receivers (932), (934) and (936) permits the calculation of position within two or three physical dimensions using ordinary trigonometric calculations. The inventive method also has sufficient resolution to permit the calculation of attitudinal data by detecting very fine positional differences in a plurality of reference points located at relatively close distances on a movable marker device (912). An input device of the present invention comprises a control means, a transducer means, and a mouse. In a 6D mode of operation, three-dimensional positional information with three degrees of freedom is provided to the computer.

摘要： A system and method is disclosed for compressing and decompressing composite video signals. In one type of operation, a composite video signal (e.g., an NTSC signal) is sampled and the samples compressed into 3 or 5 bit composite values depending on the type of system mode (PREVIEW or HIGHRES). For the HIGHRES mode, the compressed composite values are written into a RAM (160) for at least the four fields associated with the two most recent frames. As needed, the compressed values are transferred to a decoding engine (200) implemented in software (220). The decoding engine, without any need for phase locked loop circuitry, decompresses the data and decodes the decompressed digital composite values into YUV and/or RGB values. Also disclosed is a system and method for converting digital video data to composite video signals.

摘要： A hand held scanner (300) employs either uniformly or variably frosted scan windows (130', 130") to control illumination. For scanning color documents including books and magazines, a hand scanner (300) employs a fluorescent tube (305) mounted a certain distance above the lower surface of the scanner housing. At the fluorescent tube ends (305), corresponding to the illumination "dead space" of the fluorescent tube (305), the underlying portion of the scanner housing (330) is recessed towards the tube.
