Abstract: A tin oxide-containing polymer composite material, a process for production thereof, and use thereof for production of tin-carbon composite material containing: an inorganic tin-containing phase; and a carbon phase. Additionally, a compound of formula (I): R1—X—Sn—Y—R2 (I), wherein: R1 is an Ar—C(Ra,Rb)— radical where Ar is an aromatic or heteroaromatic ring optionally containing 1 or 2 substituents; Ra and Rb are each independently hydrogen or methyl, or together are an oxygen atom or a methylidene group (?CH2); R2 is C1-C10-alkyl, C3-C8-cycloalkyl, or R1; or R1 together with R2 is a radical of the formula A: wherein: A is an aromatic or heteroaromatic ring fused to the double bond; m is 0-2; each R radical is independently selected from halogen, CN, C1-C6-alkyl, C1-C6-alkoxy, and phenyl, Ra, Rb are as in formula (1); X is O, S or NH; and Y is O, S or NH.

Abstract: A cursor control device is provided which allows the user to have almost full use of the fingers of the hand for a wide range of tasks while the thumb is used to operate the cursor control device. The control body housing houses the cursor control means and could be secured anywhere on a hand by utilization of securing means. The cursor control device does not require any planar surfaces such as a table and can be operated in any orientation. In a preferred embodiment, the securing means is accomplished by utilization of securing body housing and the device has a capability to switch between two alternative configurations, the closed and open configurations. In the closed configuration the control body housing is placed on the securing body housing and could be held in a grip while thumb is free to operate the cursor control means.
