A method, apparatus and computer program product are provided for conveying information regarding the antenna configuration and / or the transmission diversity scheme to a recipient, such as a mobile device. In particular, information regarding the antenna configuration and / or the transmission diversity scheme can be conveyed by appropriately mapping a physical broadcast channel within a sub-frame so as to include reference signals indicative of different antenna configurations or transmission diversity schemes. Alternatively, masking, such as cyclic redundancy check masking, can be used to provide information regarding the antenna configuration and / or the transmission diversity scheme.

A method of adjusting the N components of an N component colour signal (such as the 3 components of an RGB colour signal) with respect to colour temperature of illuminating light when imaging a coloured subject, comprising the step of computing the difference between each of the components of the colour signal for different temperatures of illuminating light, using an algorithm based on the spectral sensitivity of the imaging means and Planck's equation defining black body illumination to obtain N components whose values are independent of the colour temperature of the illuminating light. Normalisation of the adjusted values renders the values independent of intensity of illumination and can also reduce the processing time for further processing of the signals. A technique for compensating for gamma correction which is commonly built in cameras, is disclosed.

An electronic system that monitors a trailer hitch assembly having a plate hitch with a throat for receiving a kingpin of a trailer and a locking mechanism for locking the kingpin within the throat. The electronic system determines whether the trailer hitch assemblies is properly coupled to the trailer, and comprises a first magnet creating a first magnetic flux, and a first Hall-effect sensor for sensing the position of the kingpin of the trailer relative to the throat of the hitch plate by measuring the first magnetic flux. The system further comprises a control circuit operably coupled with the first Hall-effect sensor in determining whether the first magnetic flux indicates a proper location of the kingpin of the trailer relative to the throat of the hitch plate. The electronic system discriminates between the kingpin and foreign materials, thereby assuring proper locking of the locking mechanism.

The invention discloses a push method and device for commodity information. According to the method, commodity price ranges are determined according to the number of times of network behaviors on commodities by users, and can be distinguished accurately and reliably, and therefore complete price range data can be obtained, and the problem that due to the fact that the price ranges of the commodities are divided according to the commodity price in the prior art, the price range data are not accurate can be solved. The purchasing power ranges of the users are determined according to the number of times of the network behaviors on the commodities by the users and the commodity price ranges, the commodity information corresponding to the purchasing power ranges of the users is pushed to the users, effective and accurate commodity information push can be carried out on the basis of the accurate and complete item price range data, and the problems that the accurate commodity information can not be searched and matched when the commodity information is pushed in the prior art, the searching and matching operation takes up system resources excessively, and the system treatment efficiency is lowered are solved.

A power tool includes a clamp shaft for clamping a tool accessory to the power tool and a clamp shaft holding mechanism for selectively locking the clamp shaft to hold the clamp shaft in a position that secures the tool accessory on the power tool. The power tool also includes a lever for shifting the clamp shaft holding mechanism between clamped and unclamped states. The lever is configured such that when an operator grasps the lever and moves it toward a position for releasing the tool accessory, the lever and the operator's hand move away from the tool accessory.

A two-dimensional code having a rectangular region is provided. In the rectangular region, there are a plurality of code blocks, a first specific pattern, and error-correction code blocks. Each code block is composed of a plurality of cells aggregated together and formed to have both a specified corner in the rectangular region and the plurality of code blocks arranged in the rectangular region. The specific pattern is used to specify the positions of the cells. The error-correction code blocks are contained in the code blocks and formed to correct an error. The error-correction code blocks are arranged contiguously to part of the borders of the rectangular region. The part of the borders is displaced from the first specific pattern. Compressed data code blocks are also arranged in the same way as the error-correction code blocks.

A device and a method of monitoring a fuel metering system of an internal combustion engine, in particular a common rail system. The fuel is compressed by a pump, and a pressure variable characterizing the fuel pressure is determined. An error is detected when a filtered pressure variable deviates from a threshold value.

A moisture sensing system of the present invention includes first and second sensor arrays, at least one optical system operative to image the same portion of the surface onto both of the sensor arrays, and a processing system in communication with the sensor arrays and operative to analyze images from the sensor arrays to detect moisture. The sensor arrays may be two-dimensional sensor arrays that are separate or different portions of the same sensor array. This system may be used to control the windshield wipers of a vehicle. The processing system may be configured to subtract an image obtained from the first sensor array from an image obtained from the second sensor array to distinguish between near field and far field objects.

A method and a system is for evaluating the transmitted signals of a probe system, which has a probe element that is deflectable out of a rest position and which generates transmitted signals, which include a switch-on signal during a deflection of the probe element out of its rest position and which, together with interference signals, are transmitted to a receiving unit, in which the received signals made up of the transmitted signals and the interference signals, are compared to a reference signal. In this context, the reference signal is formed by interlinking information signals generated from the received signals, and the interference signals, and / or the received signals are differentiated by time, prior to the comparison with the reference signal.

A visible light communication (VLC) receiver captures frames of a scene with a camera to detect flashing light signals from a VLC transmitter such as an array of LEDs. The method assembles an enhanced dynamic range image sequence from the frames. At least one VLC source is detected in the enhanced sequence, wherein the source occupies a respective subwindow within the scene. An imaging exposure such as the exposure time used for capturing images at the subwindow is optimized according to a brightness of the respective VLC source. Then a plurality of subwindow images are captured using the optimized exposure. VLC data visible in the subwindow images is then decoded.
