Abstract: A new computer word game with an action element where word holders fall from the top of the display area, with the goal being to throw letters upwards into each word holder to form a complete valid word in its letter spaces before the word holder reaches the bottom of the display. The player controls a letter selector and selects a letter to throw from a letter depot containing random letters. Word holders appear at random horizontal positions at the top of the display and are of various sizes depending on how many letter spaces they contain. When all letter spaces in a word holder are filled and form a valid word, the word holder disappears and the player is awarded points. If a word holder reaches the bottom of the display before the player has formed a valid word in all its letter spaces, the word holder disappears and the player looses a life. Letters successfully used in a word holder, or lost when the word holder reaches the display bottom are randomly replaced in the letter depot's empty spaces.

Abstract: A self-contained pen computer which is capable of collecting and recording data representative of handwritten strokes of the pen, and displaying such data in a display screen which is a part of the pen. In the housing of the pen, a pressure sensor is included at the tip of the pen, and a motion sensor which outputs signals describing the motion of the pen, so that handwritten data can be acquired without the need for a special writing surface. These sensors are connected to a signal processing circuit which includes an analog-to-digital converter to convert motion signals and pressure sensor signals into digital code. A microprocessor or microcontroller interprets the digitized motion data, stores the processed data in a memory such as a chip storage device, directs such data to a built-in display such as an LCD, which can display images in real-time corresponding to the processed motion signals, as well as images stored in memory.
