Abstract:
The invention relates to the use of solid betaine for de-icing and/or preventing slipperiness. The solid betaine comprises at least one non-betaine compound affecting water and/or moisture movement in said solid betaine. The invention further relates to a process for the manufacture of solid betaine. A suspension comprising betaine crystals is prepared from a feed liquid and the betaine crystals are separated and washed. The amount of wash liquid is adjusted in order to leave 0.5 to 10 w-% of at least one non-betaine compound in said solid betaine.
Abstract:
Disclosed herein are apparatus, method, and computer program whereby a signal generated by a touch screen device is received in response to a tactile input from a user on an input surface of the touch screen panel. In response, presenting information to a user, the information comprising a warning that the user is exerting an excessive amount of force on a surface of the touch screen panel.
Abstract:
An apparatus, method and computer program product are provided for using varying numbers of tactile inputs to manipulate different features of an electronic device. In particular, varying numbers of tactile inputs resulting from a user touching the electronic device touchscreen or touchpad may be used in order to adjust the speed of movement of an image displayed on the electronic device. Varying numbers of tactile inputs may likewise be used to adjust in various manners an adjustable feature represented by an icon displayed on the electronic device display screen. Finally, varying numbers of tactile inputs may further be used in order to unlock an electronic device in a secure, yet simple, manner.
Abstract:
A hinge has two hinge parts for connecting two device parts of a portable device. The hinge parts can be moved relative to each other so as to allow the portable device to operate in a number of positions. For example, in a mobile phone with a sliding cover to expose the phone keyboard when the mobile phone is operated in an open position, the hinge parts are also configured to allow the sliding motion of the sliding cover. Furthermore, electrically conductive segments are provided on the hinge parts so that electrical contacts between the device parts can be achieved when the portable device is operated in different positions. Additionally, an optical conduit is provided through the hinge so that optical signals can be conveyed between the device parts when the portable device is operated in different positions.
Abstract:
A device (1) such as a laptop computer includes a fingerprint sensor (21) and has a specific function to be performed associated with at least two of the fingerprints of an authorized user of the device (1). The device performs the specific function when an authorized user places a finger on the fingerprint sensor (21). The functions associated with the fingerprints of the authorized users can be quickly- accessed even when a security or keyboard lock is active. A mobile communication terminal' (1) includes a fingerprint sensor (21) in a call handling key (11). Calls are answered, rejected or initiated when an authorized user places a finger on the fingerprint sensor (21).
Abstract:
An apparatus comprising: at least one light source; a selective attenuation element, used for a plurality of adjacent pixels and configured to attenuate light from the at least one light source; and a group of adjacent mono-chrome light filters, used for the plurality of adjacent pixels, the group comprising: a first mono-chrome light filter, for a first one of the plurality of adjacent pixels, configured to filter light transmitted via the selective attenuation element for the first one of the adjacent pixels; and a second mono-chrome light filter, for a second one of the plurality of adjacent pixels, configured to filter light transmitted via the selective attenuation element for the second one of the adjacent pixels.
Abstract:
An apparatus comprising: a sensor network comprising: a first plurality of rows, a second plurality of columns and a third plurality of sensor elements wherein each sensor element is associated with a unique combination of a row and a column but not every unique combination of row and column is associated with a sensor; selection circuitry configured to concurrently select a group of the first plurality of rows; reading circuitry configured to concurrently read columns during a concurrent selection; and control circuitry configured to determine the group of the first plurality of rows that are concurrently selected.
Abstract:
In accordance with an example embodiment of the present invention, an apparatus comprising a data control line configured to comprise data for subsequent viewing on a display. Further, the apparatus comprises a refresh control line configured to update at least one pixel on a display; a frequency based selector coupled to the refresh control line; and a memory coupled to the frequency based selector and the data control line. The apparatus is configured to provide one or more signals to a pixel in a first mode of operation and a second mode of operation based at least in part on the refresh control line.
Abstract:
It is disclosed to measure the impedance of a read-out line. The read-out line includes at least two cascaded electrical circuit segments, each electrical circuit segment including two longitudinal arms, wherein one of the longitudinal arms includes an electrical component, and a lateral arm including a switch configured to close in the presence of an object in the vicinity of the switch. The measured impedance of the read-out line can be compared to a preset value corresponding to an allowable value of the impedance of the read-out line.
Abstract:
An apparatus comprises an arrangement of display pixels and reflectors arranged to reflect ambient light passing through the display pixels. The reflectors are electrically controllable, in order to enable an optimization of the portion of the ambient light that is reflected by the reflectors. A required adjustment of such electrically controllable reflectors can be determined, and the reflectors can then be controlled accordingly.
