A switch, keyboard and associated methods are provided. In one implementation, the switch includes a housing having a protruding portion configured to be received in an aperture formed on a substrate, a plunger operable to move with respect to the housing, a first contact member located in the housing, and a second contact member extending from the protruding portion of the housing. The second contact member is operable to, based at least in part on the plunger being moved in a first direction, deform to a predefined extent to electrically contact the first contact member. The switch provides a low profile appearance but not compromising the smooth and quickly responsive striking motion for a mechanical switch, such that a clean design can be provided while the input experience and durability are maintained. A keyboard is also provided.

Described are examples of an input device having a wheel with a plurality of teeth, where at least the plurality of teeth are composed of a ferrous or magnetic material. A magnet is disposed to provide a first magnetic field that attracts the ferrous or magnetic material of the plurality of teeth to provide a detent action when moving the wheel from a first position to a second position. A magnet sheet is disposed to provide a second magnetic field that causes the magnet sheet to deform based on magnetic attraction to the ferrous or magnetic material of the plurality of teeth when moving the wheel from the first position to the second position. A strain sensor coupled to the magnet sheet can detect a strain caused by deformation of the magnet sheet, and provide an electronic signal indicating the strain.

A method of obtaining a disparity vector and its encoding/decoding in the multi-view coding process is disclosed. The present invention includes essentially: determining a disparity vector between two views during the multi-view image coding, and computing a disparity vector between the other two views according to the disparity vector between the two views and the known relative location information between each of the views. Thereafter, the disparity vector is used for multi-view encoding/decoding. The present invention further makes use of the correlation between the disparity vector and depth information of the spatial vector on one hand, and on the other hand makes use of the direct relationship between the disparity vector and the location of each of the cameras. It is experimentally proved that the disparity vector between several views can be accurately computed during the multi-view coding, thereby improving the performance of multi-view coding.

A method and apparatus for performing arithmetic encoding/decoding in an arithmetic encoder is disclosed. It comprises: firstly, when performing binary arithmetic encoding/decoding in the arithmetic encoder, an interval update process for arithmetic encoding/decoding to be performed in the original domain is mapped to the logarithm domain, and the interval update computation is implemented with direct add/subtract operations; during arithmetic encoding/decoding in the logarithm domain, data conversions between the original domain and the logarithm domain are performed by approximations; and after encoding/decoding a symbol, its probability is updated when necessary, the update being performed with add/subtract operations in the logarithm domain. It can be seen that with the arithmetic encoding/decoding solutions of the disclosure, the arithmetic encoding/decoding process and the probability estimation involved therein are mapped to the logarithm domain. Data conversions between the original domain and the logarithm domain are performed by means of approximation equations. Accordingly, complicated computations and table looking-up are avoided effectively. Therefore, the disclosure provides a simple, efficient and suitable solution for performing arithmetic encoding/decoding.

A binary coding and decoding method and apparatus for MVD (Motion Vector Difference) absolute values, includes: dividing symbols for MVD absolute values to be coded into a plurality of subsets according to probability distribution properties; assigning a binary codeword for each subset; assigning a binary codeword for each symbol in each subset; concatenating and outputting the binary codeword for each subset and the binary codeword for each symbol in the subset, as the binary coding result. At the decoding side, decoding operations are performed by using a principle corresponding to that at the coding side. In this manner, the invention makes full use of the source properties on one hand, and effectively prevents the codeword length from being too long on the other hand. It has been experimentally testified that a better compression effect may be achieved during arithmetic coding process and thus the image coding performance may be improved effectively.
