Abstract: A radio frequency (RF) weak magnetic field detection sensor includes a ferromagnetic core, a pickup coil disposed to surround the ferromagnetic core, a substrate that includes an opening, a core pad connected to the ferromagnetic core and a coil pad connected to the pickup coil, and an insulating tube interposed between the ferromagnetic core and the pickup coil. The insulating tube includes a bobbin around which the pickup coil is wound, and a core hole formed to pass through the bobbin and configured to accommodate the ferromagnetic core.

Abstract: A method for training a language model for multimodal dialog includes generating a first token sequence by tokenizing one or more text messages included in multimodal dialog data, generating a second token sequence by inserting, based on an appearance position of an image included in the multimodal dialog data, one or more image presence tokens and one or more image non-presence tokens into the first token sequence, and replacing one or more tokens among a plurality of tokens generated by the tokenization with a mask token, generating one or more feature vectors for the image, and training an artificial neural network-based language model to predict, based on the second token sequence and the one or more feature vectors, an appearance position of the image in the multimodal dialog data.

Abstract: A keypad apparatus for a touch screen and to a method for providing same. The key pad apparatus includes a plurality of buttons, a storage device, a processor, and a communication module included in the plurality of buttons and outputting, to the touch screen, a selection output signal selected from among a plurality of output signals corresponding to respective letters when a letter button to which a letter is allocated is selected. The processor selects the selection output signal from among the plurality of output signals on the basis of state information stored in the storage device, and controls the output of the selected selection output signal.

Abstract: The present invention relates to character arrangements, input methods and input device. More particularly, the present invention relates to Korean, English and symbols arrangements that are effectively arranged on a limited number of buttons, input methods using the character arrangements and input device thereof. The present invention provides fundamental and efficient character arrangements that can be applied to various input methods so that the user who is accustomed to another input method can input characters with the character arrangement of the present invention fast and efficiently.

Abstract: A key input interface method is provided. The key input interface method includes allocating key elements belonging to either a first group or a second group to a key array; and processing a key element allocated to a selected key as input, wherein the key element belonging to either the first group or the second group is identified by distinguishing a key element selection method. Accordingly, a compact electronic device is possible to have various key inputs with a limited number of keys.

Abstract: Disclosed is a method and apparatus for inputting characters as many as possible with a limited number of keys.

Abstract: Disclosed is a method and apparatus for conveniently inputting characters with both hands and inputting characters as many as possible with a limited number of keys.

Abstract: Disclosed is a method and apparatus for inputting characters through a direction input unit such as a joystick. The method of inputting characters corresponding to keys arranged on a 4-by-3 keypad by means of a direction input unit having direction buttons indicating up, down, left, and right movements, the method including: (a) assigning two direction buttons of the direction input unit to each of the keys and selecting one of the keys by pressing the direction buttons of the direction input unit; and (b) outputting a character corresponding to the selected key according to a current character mode, and sequentially changing characters corresponding to the selected key one by one and outputting a selected character other than a previous character when the key is re-selected within a predetermined time, when a supplemental button other than the direction buttons is input within a predetermined time after the key is selected, or when one of the two direction buttons being pressed is released and re-pressed.

Abstract: Disclosed is a method and apparatus for inputting characters through a pointing device such as a stylus or a mouse. The method includes: (a) dividing an input area of the pointing device into a plurality of input sub-areas and assigning a plurality of characters constituting a character set of a current character mode to each of the input sub-areas; (b) inputting an input pattern through the pointing device in a selected one of the input sub-areas; and (c) selectively outputting one of the characters assigned to the selected input sub-area according to whether the input pattern of the pointing device is a point, a line having more than a predetermined length, a line bent a predetermined number of times with more than a predetermined angle and having more than a predetermined length, or a round shape.
