1. Cylinder head for an internal combustion engine having:
a body with an upper face, a lower face, two end faces and two lateral faces,
said body integrating in a single east piece, the engine exhaust manifold,
said exhaust manifold being defined by a plurality of conduits for the exhaust gases provided in the body of the head, said conduits merging into a common outlet terminating on a lateral face of the head, and
at least one lower cooling jacket and at least one upper cooling jacket provided in the body of the head, substantially below and above conduits defining the exhaust manifold,
wherein
a) the lower cooling jacket is longitudinally divided into a plurality of separate transverse chambers associated to various engine cylinders, while the upper cooling jacket has a portion extended longitudinally over the entire extension of the head and communicating with separate transverse chambers located on the intake side of the head,
b) said exhaust conduits integrated in the head form separate subgroups of exhaust conduits merging into manifold portions superimposed and spaced apart from each other,
c) said separate subgroups of exhaust conduits terminate in said common outlet on a lateral face of the cylinder head, and
d) the lower cooling jacket has a portion thereof which extends in the area of the body of the head which separates the superimposed portions of the subgroups of exhaust conduits.
2. Cylinder head according to claim 1, further comprising holes, provided by means of a drilling operation in the casting, for placing the lower and upper cooling jacket in communication with each other in the areas at the two opposite and separate sides of the common outlet of the exhaust conduits.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for selecting items using a touchscreen, comprising the steps of:
displaying a plurality of items as icons on the touchscreen;
receiving a touch signal including information on a touch point on the touchscreen;
determining one or more selected items from among the plurality of items upon reception of the touch signal; and
executing content corresponding to the determined selected items,
wherein the content includes information on a relative distance set based on correlation with the plurality of items and, when a plurality of pieces of content is present, the pieces of content are aligned in the order of the relative distance from the content corresponding to the shortest distance and executed.
2. The method of claim 1, wherein the plurality of icons is represented as a combination of at least one of: a circle, a polygon, text, and an image displayed on a predetermined region of the touchscreen.
3. The method of claim 2, wherein the plurality of icons is displayed in the same color or different colors.
4. The method of claim 1, wherein, when the plurality of items has correlation, icons respectively corresponding to items having highest correlation therebetween are displayed closest to each other and icons respectively corresponding to items having lowest correlation therebetween are displayed with a longest distance therebetween.
5. The method of claim 4, wherein the step of determining comprises determining whether the touch point corresponds to one of the plurality of icons on the basis of the information on the touch point included in the received touch signal.
6. The method of claim 5, wherein the icon corresponding to the touch point is determined when the touch point corresponds to one of the plurality of icons and one or more icons disposed within a predetermined distance from the touch point are determined when the touch point does not correspond to any of the plurality of icons.
7. The method of claim 6, wherein an icon indicating an item having low correlation with an item corresponding to an icon closest to the touch point is excluded from the determined icons,
wherein the distance between the touch point and the icon is normalized to a value in the range of 0 to 1 using a distance vector.
8. The method of claim 6, wherein the step of determining comprises determining whether a dragging operation of moving the touch point is performed on the basis of the information on the touch point included in the received touch signal.
9. The method of claim 8, wherein one or more items corresponding to the determined icons are determined as selected items when the dragging operation of moving the touch point is not performed and one or more items corresponding to one or more icons disposed within the dragging range of the dragging operation are determined as selected items when the dragging operation of moving the touch point is performed.
10. The method of claim 1, further comprising displaying connections between the one or more icons indicating the determined selected items and the touch point.
11. The method of claim 10, wherein connections between the one or more icons corresponding to the determined selected items and the touch point are sequentially displayed from the icon closest to the touch point.
12. The method of claim 1, wherein, when the content corresponds to music files, the music files include information on the relative distance set according to correlation with the plurality of items,
wherein the music files are searched in the order of the relative distance from the music file corresponding to the shortest distance and a predetermined number of music files is executed without being repeated.
13. A system for selecting items, comprising:
a touchscreen including a display unit for displaying a plurality of items as icons and an input unit displayed on the display unit and displaying coordinate data corresponding to a touch applied to the display unit;
a storage unit storing content;
a controller operated by a predetermined program executing a set of instructions embodied in a non-transitory computer-readable medium to control the display unit of the touchscreen and the storage unit on the basis of a touch signal received through the input unit of the touchscreen; and
an output unit for outputting the content under the control of the controller,
wherein the predetermined program includes commands for performing the following steps:
displaying the plurality of items as icons on the touchscreen;
receiving the touch signal including information on a touch point on the touchscreen;
determining one or more selected items from among the plurality of items upon reception of the touch signal; and
executing content corresponding to the determined selected items,
wherein the content includes information on a relative distance set based on correlation with the plurality of items and, when a plurality of pieces of content is present, the pieces of content are aligned in the order of the relative distance from the content corresponding to the shortest distance and executed.
