Abstract: Portable devices are usually synchronized with servers like personal computers. Furthermore, most portable devices provide a user with the possibility to generate data objects or to obtain data objects from other sources than the personal computer. This means that of certain data objects a backup exists, as they are stored on the personal computer. Other data objects are unique, as the user does not have a backup at his or her disposal. Energy is a precious commodity in portable devices. A memory, in particular a volatile memory, consumes power. In case energy is required for keeping data objects stored, of which no backup is at the disposal of the user, but this energy might not be available in the future due to battery level, storage of data objects of which a backup exists is sacrificed for the benefit of storage of data objects for which there is no backup.

Thus data is available for undocked use of device (1). Power consumption is reduced as use of the wireless connection is avoided.

Abstract: The present invention relates to a tracking picture tube of the type in which comb-shaped electrodes or optical detecting means (12, 13) are used for generating a signal related to the position of an electron beam with respect to the strips (5). The tube is characterized in that the deflection unit is arranged to deflect the beams (21r, 21g, 21b) onto selected strips (22r, 22g, 22b) having coincident sides which neighbour finger portions (14, 15) of the same electrode (12, 13), and the selected strips (22r, 22g, 22b), excited by the electron beams, are separated by at least one unexcited strip, respectively.

Abstract: Picture display device (1) comprising a cathode ray tube (2) whose display screen (4) is provided with parallel image lines (10) along which an electron beam (5) is scanned, and with pairs of first and second phosphorescent index elements extending along opposed sides of each image line (10). The device also comprises a pair of photodetectors (31,32) for generating index signals indicative of the amount of irradiation by the electron beam (5) of said index elements. An error signal is constructed based on a difference of said index signals for correcting the shape and/or the position of the electron beam (5) on the screen. The index signal of one of the photodetectors is indicative of the amount of irradiation of both the first and the second index elements (11, 12), which improves the detection efficiency of said detector and the signal/noise ratio of its index signal. This results in a better error signal and thus in a better image quality.
