The invention concerns a method of forming a graphene device, the method comprising: forming a graphene film (100) over a substrate; depositing, by gas phase deposition, a polymer material covering a surface of the graphene film (100); and removing the substrate from the graphene film (100), wherein the polymer material forms a support (102) for the graphene film (100).

A method, system, and computer program product for encoding a key touch on a device. The method may include detecting a key touch at one of two of more subareas of a key area and encoding the detected key touch into one code of a plurality of codes. Each code may be associated with one key area and one subarea of the key area. The method may perform an operation to determine whether to authorize access to a resource by determining whether the code, at least in part, authorizes the access. The key area may be marked with an indicia. The two or more subareas of the key area may be unmarked and may be of equal size. The key area may be divided into the two or more subareas by specifying two or more subregions of sensor pixels of a region of sensor pixels of a touch-sensitive screen.

The present invention relates to a method, which is operated by a control unit, and which enables the user to select any of the menu elements and switchover between menus at the main display menu of the machines desired to be interacted, or within an application installed on such device. By virtue of said method, the menu elements can be present on the display according to the level cluster of a cone-shaped function with any set of parameters, but also the positioning of the menu elements can also be performed according to the position of the pointer (M) after interacting with the machine. Upon interaction with the machine the corresponding menu element/elements is/are magnified according to the position of the pointer (M). The size of the elements deviated from due to movement of the pointer is reduced, while the elements converged to are magnified. Moreover, the position of the elements can be altered in the movement direction or a certain direction depending on the reverse direction according to the position of the pointer (M).

An irradiation optical system includes a uniformizing section and an irradiation lens section. The uniformizing section brings in-plane distribution of light emitted from a light source, close to uniform in-plane distribution. The irradiation lens section diffuses the light in a predetermined direction. The in-plane distribution of the light is brought close to the uniform in-plane distribution by the uniformizing section. The irradiation lens section includes, in order from the light source, a first cylindrical lens and a second cylindrical lens each having negative refractive power in the predetermined direction.

Disclosed are an electronic apparatus and a method of controlling the same. The electronic apparatus includes a camera, a display, a memory, and a processor configured to execute at least one instruction to: detect a plurality of fingers in a plurality of first image frames obtained through the camera and, in response to an identification that a pose of the plurality of detected fingers corresponds to a trigger pose, enter a character input mode, detect a first motion of a finger among the plurality of fingers in a plurality of second image frames obtained through in the character input mode, identify a key corresponding to the first motion, from among a plurality of keys mapped to the finger, based on a position of the finger by the first motion and a reference point set to the finger, and control the display to display information corresponding to the identified key.

During control of a user interface via free-space motions of a hand or other suitable control object, switching between control modes can be facilitated by tracking the control object's movements relative to, and its contact with a “virtual touch plane or surface” (i.e., a plane, portion of a plane, and/or surface computationally defined in space, or corresponding to any physical surface).

A method of controlling a display device includes the steps of displaying a first image in a first size on a display surface, displaying the first image and a second image which has the first size and is different from the first image on the display surface when an operation of changing a size of the first image is started, displaying the first image in the first size on the display surface when the operation continues, displaying the second image in a size different from the first size on the display surface based on the operation when the operation continues, and displaying the first image in a second size based on the operation on the display surface when the operation terminates.

Within many applications impulse radio based ultra-wideband (IR-UWB) transmission offers significant benefits for very short range high data rate communications when compared with existing standards and protocols. In many of these applications the main design goals are very low power consumption and very low complexity design for easy integration and cost reduction. Digitally programmable IR-UWB transmitters using an on-off keying modulation scheme on a 0.13 microns CMOS process operating on 1.2V supply and yielding power consumption as low as 0.9 mW at a 10 Mbps data rate with dynamic power control are enabled. The IR-UWB transmitters support new frequency hopping techniques providing more efficient spectrum usage and dynamic allocation of the spectrum when transmitting in highly congested frequency bands. Biphasic scrambling is also introduced for spectral line reduction. Additionally, an energy detection receiver for IR-UWB is presented to similarly meet these design goals whilst being adaptable to address IR-UWB transmitter specificity.
