摘要： System and methods for querying digital image archives containing digital photographs and/or videos (collectively, “digital images”). The digital images are indexed in accordance with a plurality of recorded parameters including time, date and geographic location data (altitude and longitude), as well as image data such as lens focal length, auto focus distance, shutter speed, exposure duration, aperture setting, frame number, image quality, flash status and light meter readings, which are used for searching a database consisting of the digital images. These images are preferably generated by an image capturing system which is capable of measuring and recording a plurality of parameters with each captured digital image. The image retrieval system allows a querying user to search the image archive by formulating one or more of a plurality of query types which are based on the recorded parameters, and then retrieve and display those images having the specified parameters.

摘要： A system and method for modulating the switching factor of a circuit to control heating and which does not require modulation of the circuit's clock frequency. The switching factor refers to the fact that due to gating requirements, latency and data transfer characteristics, the rate at which a circuit's inputs are addressed is some fraction of the circuit clock frequency. Application can be made to many existing systems which incorporate single or multiple VLSI circuits such as superscalar microprocessors, parallel processors, DSPs, microcontrollers and MPEG decoders. A method for controlling a switching factor of a multi-functional unit processor includes the steps of: scheduling instructions stored in a memory for execution on each functional unit; generating a first temperature signal for a first functional unit and a second temperature signal for a second functional unit, each temperature signal being a function of a temperature associated with each functional unit; identifying the first functional unit and the second functional unit associated with each temperature signal, responsive to the generating step; comparing the first temperature signal with a first predetermined temperature threshold signal; generating a first temperature delay signal when the first temperature signal exceeds the first predetermined threshold, responsive to the comparison; and reducing the switching factor of the first functional unit according to the first temperature delay signal by delaying scheduling instructions for execution on the first functional unit. Further reduction in power dissipation may be achieved by using thermal feedback to cooperatively vary the voltage and frequency of a circuit.

摘要： An image capturing system and method for automatically watermarking a plurality of recorded camera and image parameters such as the location (latitude, longitude and altitude), orientation of the principal axis of the camera, whether the camera is in landscape mode or portrait mode, camera velocity, photographer information, time and date, zoom factor, shutter speed, flash on/off, autofocus distance, lightmeter reading, focal length and aperture into every captured image. This watermarked data can be subsequently extracted and compared with the originally recorded data so as to verify the authenticity of a corresponding image. Since the critical data is invisibly watermarked into the image, it is difficult to modify the image without affecting the watermarked data.

摘要： A system and method for optimizing power consumption by a disk drive unit. The system and method monitor and analyze historical use data and calculate a predicted inactivity duration. The predicted inactivity duration is used to power-down the rotational speed of the drive to the first of one or more intermediate rotational speeds. Continued inactivity will result in further speed reduction until the drive is ultimately powered off. The drive increases rotational speed on demand.
