A computer-implemented method for use in conjunction with a computing device with a touch screen display comprises: detecting one or more finger contacts with the touch screen display, applying one or more heuristics to the one or more finger contacts to determine a command for the device, and processing the command. The one or more heuristics comprise: a heuristic for determining that the one or more finger contacts correspond to a one- dimensional vertical screen scrolling command, a heuristic for determining that the one or more finger contacts correspond to a two-dimensional screen translation command, and a heuristic for determining that the one or more finger contacts correspond to a command to transition from displaying a respective item in a set of items to displaying a next item in the set of items.

Light emitting diodes (LEDs) are on the verge of a breakthrough in general lighting, due to their rapidly improving efficiency. Currently, white LEDs with high color rendering are mainly based on wavelength conversion by one or more phosphor materials. This Review first describes how to quantify the quality of a light source, discussing the color rendering index (CRI) and alternative color quality indices. Then, six main criteria are identified and discussed, which should be fulfilled by a phosphor candidate to be considered for actual application in LEDs. These criteria deal with the shape and position of the emission and the excitation spectra, the thermal quenching behavior, the quantum efficiency, the chemical and thermal stability and finally with the occurrence of saturation effects. Based on these criteria, the most common dopant ions (broad-band emitting Eu 2+ , Ce 3+ and Mn 2+ , line-emitting rare earth ions,...) and host compounds (garnets, sulfides, (oxy)nitrides,...) are evaluated. Although many phosphor materials have been proposed in literature in recent years, the number of phosphors effectively fulfilling all six requirements is relatively small.

Selecting Conversion Phosphors for White Light-Emitting Diodes

Cases or holders for cell phones, personal digital assistants, portable video/music players, electronic books, electronic tablets and other handheld and/or free-standing display devices, as well as the devices themselves are disclosed. In different embodiments, a versatile protective holder that can allow placement on any surface for hands-free viewing, with full adjustment of viewing angle in landscape and/or portrait orientations; directional sound reflecting and baffling; easier cleaning and viewing of the device's screen; easier grasping by the user; wearing of the device using a belt clip or arm or waist band; as well as attachment to an automobile, bicycle, or other vehicle are disclosed.

The disclosed technology provides micro-assembled micro-LED displays and lighting elements using arrays of micro-LEDs that are too small (e.g., micro-LEDs with a width or diameter of 10 μm to 50 μm), numerous, or fragile to assemble by conventional means. The disclosed technology provides for micro-LED displays and lighting elements assembled using micro-transfer printing technology. The micro-LEDs can be prepared on a native substrate and printed to a display substrate (e.g., plastic, metal, glass, or other materials), thereby obviating the manufacture of the micro-LEDs on the display substrate. In certain embodiments, the display substrate is transparent and/or flexible.

A hand-held electronic device with a keyboard, thumbwheel, display and associated software is optimized for use of the device with the thumbs. The associated software has a plurality of features to optimize efficient use of the limited keyboard space and encourage the use of the device by thumb-based data entry through the thumbwheel and/or through a combination of minimal number of keystrokes. Software features include international character scrolling, and auto-capitalization. The keys on the device keyboard are optimally shaped and configured for thumb-based input. In addition, the thumbwheel is inclined between the front and a side edge of the device so as to be reachable by either the thumb or index finger of the user's hand at the side edge of the device.

Hand-held electronic device

A sliding/swing-type portable apparatus having a self-retaining function includes a main body; a battery cover coupled to the bottom surface of the main body in a predetermined position so that it can rotate about a first hinge axis toward or away from the main body and provided with a folding force, at less than a first angle relative to the bottom surface of the main body, in such a direction that it is folded on the main body, an unfolding force at the first angle or more, and a retaining force at a second angle for retaining the main body in an upright position, at a slant; and a battery pack attached to and detached from the battery cover.

An integrated mobile phone and personal digital assistant that includes a telephone keypad which folds onto a personal digital assistant screen with the keypad exposed, and slides to expose a portion of the screen, and unfolds to expose the entire screen, thereby allowing both devices to share a single screen for their respective operations.

Combined mobile telephone and personal digital assistant

A personal digital assistant (PDA)/telephone combination device comprising a base, a screen coupled to the base and a keypad hingably mounted to the base, the keypad providing a partial view of the screen in a lowered position and a full view of the screen in a raised position.

Personal digital assistant/telephone combination device

A wireless cell phone comprising a handset, a keypad assembly rotatably coupled to the handset, and a handset cover rotatably coupled to the handset. The keypad assembly is rotatable about at least two axes, and removable from the handset. The keypad assembly has a first side for a telephone keypad and a second side for a data communication keypad. The handset cover is rotatably coupled to the handset and includes an exterior display and an interior display. The exterior display is capable of displaying electronic information when the handset cover is in a folded position with respect to the handset.

Wireless cell phone

The present invention relates to a semiconductor package which is loaded with a plurality of high-performance integrated circuits for high-performance systems such as super computers and large-sized computers. According to the invention, the packaging density of the semiconductor is doubled by stacking upper and lower members and forming substrates loaded with a plurality of chips in a multistep structure so that the size of computers can be minimized and heat emission efficiency can be improved by forming heat sinks in a fin-pin shape.
