Abstract: A method of displaying digital images is described in which a display length indicator is received and digital images are accessed. A set of digital images are selected from the accessed digital images in accordance with the display length indicator and displayed in a predetermined order. The method may be performed by a computer program, which may be embodied on a computer readable medium.

Abstract: An electronic module that inserts into or is otherwise associated with a pen or other writing instrument. The electronic module includes a mechanism, such as an accelerometer, for detecting pen motion. The electronic module is preferably mounted in a substitute ink cartridge for a pen. Ballistic information generated by the accelerometer is transmitted via the radio transmitter to a computer (e.g., a personal computer), where processing and/or storage of the accelerometer information may occur. The accelerometer information may be used, for example, for handwriting recognition or digital ink generation. The electronic module is preferably provided in a casing that is shaped like an ink cartridge. Contemporary pens usually include two cartridges within the pen, a first that supplies ink to the nib, and a second that presses the first against the nib. The components may be mounted in a cartridge that is placed in the position of the second cartridge.

Abstract: A system that can enhance cognitive ability by viewing sequences of images captured during an event is disclosed. For example, the innovation can employ captured event sequences to improve failing memories in patients with a diagnosed memory condition such as acquired brain injury or neurodegenerative disease such as Alzheimer's disease. These event sequences can be captured in the point-of-view of a user (e.g., first person) as well as from a third person or other monitoring location (e.g., car).

Abstract: A user interface is described which includes electrical connections arranged in a pattern on a writing surface. An input is made by a user by drawing lines on the writing surface using a pencil or pen with conductive ink so as to electrically connect together two or more of the electrical connections.

Abstract: A method, apparatus, and article of manufacture altering a displayed image presented to a user on a viewing device using the proximity of the user to the viewing device to determine how the displayed image is to be presented. The viewing device includes a plurality of proximity sensors that are used to determine the location of a user to the viewing device. As the user moves his or her position relative to the viewing device, the proximity sensors detect the change in the user position. These changes in detected position are used to alter the image being displayed upon the viewing device.

Abstract: A method, apparatus, and article of manufacture altering a displayed image presented to a user on a viewing device using a user-controlled orientation of the viewing device to determine how the displayed image is to be presented. The viewing device includes a plurality of tilt sensors that are used to determine the orientation of the viewing device. As the user moves the orientation of the viewing device, the tilt sensors detect the change in the device orientation. These changes in orientation are used to alter the image being displayed upon the viewing device.

Abstract: A method and system that converts ballistic movement of a pen (e.g., movement of a pen point across a surface) into thickness information for digital ink data. The pen includes at least one accelerometer that is used to generate the ballistic information. A thickness conversion component may be located on a computer that is remote from the pen, and the ballistic information is transmitted to the computer via a hardwired or wireless connection. The accelerometer generates the ballistic information in the form of pulses, the width of which is directly related to the acceleration of the pen movements. The thickness conversion component converts the acceleration information, with or without additional information such as coordinate information, into thickness information for digital ink. This thickness information may be used to generate variably thick lines, which may be useful for a variety of applications, for example, better display and improved recognition.

Abstract: A portable computer arranged to rest comfortably in the hand has a small display screen. Accelerometers capable of detecting movement of the pen with respect to gravity provide input to a microcontroller which selects a response from a number of viewing modes. The pen may be held in either hand and the output message to the screen will be oriented according to the location of the pen. Full personal digital assistance functionality may be incorporated in a relatively small plastics casing and functions, such as calendar, contracts the like may be incorporated.

Abstract: A small wearable recall device is provided to capture images triggered by a combination of a detection of a capture condition (e.g., changes in motion, temperature or light level) followed by a relatively stable period, as detected by an accelerometer. By triggering on the combination of a detected capture condition followed by a detected stability condition, a clearer image of the environment of an interesting event is expected to be captured. The small size of the recall device makes it possible to integrate it into common portable consumer products, such as MP3 players, purses, clothing, hats, backpacks, necklaces, collars, and other human-wearable products.

Abstract: Methods and apparatus for distributing power and data to devices coupled to the human body are described. The human body is used as a conductive medium, e.g., a bus, over which power and/or data is distributed. Power is distributed by coupling a power source to the human body via a first set of electrodes. One or more devices to be powered, e.g., peripheral devices, are also coupled to the human body via additional sets of electrodes. The devices may be, e.g., a speaker, display, watch, keyboard, etc. A pulsed DC signal or AC signal may be used as the power source. By using multiple power supply signals of differing frequencies, different devices can be selectively 15 powered. For example, a 100 Hz signal may be used to power a first device while a 150 Hz signal may be used to power a second device. Digital data and/or other information signals, e.g., audio signals, can be modulated on the power signal using frequency and/or amplitude modulation techniques.

Abstract: An electronic stylus system includes an electronic stylus and base receiving unit. The electronic stylus includes a first ultrasonic transmitter, a second ultrasonic transmitter, an electromagnetic transmitter, and a writing tip. The base receiver unit includes a first ultrasonic receiver, a second ultrasonic receiver, and an electromagnetic receiver. The ultrasonic receivers of the base unit are operable to receive signals transmitted by the ultrasonic transmitters of the electronic stylus. Similarly, the electromagnetic receiver of the base unit is operable to receive signals transmitted by the electromagnetic transmitter of the stylus. The location of the tip of the electronic stylus relative to a given reference point is determined using the locations of two ultrasonic transmitters relative to the two ultrasonic receivers.

Abstract: A system and process for determining the location of persons and objects using transmitters (TXs) that transmit location messages to at least one receiver connected to a computer, in a network of computers. The TXs are small, battery-powered, radio frequency transmitters carried by the person or object whose location is being tracked. The location message signals are picked up by one or more receivers (RXs) scattered throughout an environment. Each TX transmits a code with a unique identifier, and each RX also has a unique identifier. The RXs measure the signal strength of each location message transmission. Each RX is connected to a computer, which is in turn connected to a network. The RX computers send the data messages including the TX identifier, radio signal strength, and RX identifier to a central computer via the network. The central computer uses this information to determine the location of the TXs.
