Abstract: A method and apparatus for event-tagging data entries as separate data segments in a data file. The data file is stored in the memory of a computer including a processor that executes instructions to carry out the method of the invention. As a user enters data, such as with a computer "pen" in a pen-driven notebook computer, the processor determines whether each data entry is one of a set of predefined data entry events. Such events may include areas on the screen that the user is entering his or her notes, such lines or paragraphs, such that whenever the user begins a new line or paragraph, that is tagged as a new event. An event may also be a particular time interval; for instance, data entry may be tagged every minute, or every ten minutes. An event may also relate to the type of data that the user is entering, such as graphical data vis-a-vis handwritten or text data, and/or may relate to the fact that a given data entry is of a different type of data than an adjacent data entry.

Abstract: A device for determining size variations of tissue particles. The device includes a light source and an illuminating light guide capable of irradiating light into a human tissue to produce back-scattered light, and at least two receiving light guides at different radial distances from the illuminating light guide, for receiving back-scattered light from the tissue. The device can be used for determining size variations of tissue particles such as mitochondria.

Abstract: The present invention provides an "alert" interface for a component which can be safely "hot-plugged/unplugged" to an "alert" interconnect of an electrically powered system. The alert interface has a mating edge which includes daughter precharge/ground connectors, a daughter (engage) waning connector, a number of daughter signal connectors and a daughter engage connector. The alert interconnect includes corresponding mother connectors. The respective connectors of the interconnect and the interface are arranged so that they mate in the following exemplary order when the interface is hot-plugged/unplugged to the interconnect: precharge/ground connectors, warning connectors, signal connectors and finally engage connectors. When the daughter (engage) warning connector mates with the mother warning connector, the component sends an "engage warning" signal to the powered system.

Abstract: There is disclosed a cover for protecting the leads extending between a silicon chip device and an associated printed circuit board and their electrical connections with the board. The cover is formed out of clear plastic allowing inspection of the chip device and has several legs for securing and maintaining the cover on the board and has openings that allow for cooling of the chip device.

Abstract: A system for automatically encrypting and decrypting data packet sent from a source host to a destination host across a public internetwork. A tunnelling bridge is positioned at each network, and intercepts all packets transmitted to or from its associated network. The tunnelling bridge includes tables indicated pairs of hosts or pairs of networks between which packets should be encrypted. When a packet is transmitted from a first host, the tunnelling bridge of that host's network intercepts the packet, and determines from its header information whether packets from that host that are directed to the specified destination host should be encrypted; or, alternatively, whether packets from the source host's network that are directed to the destination host's network should be encrypted.

Abstract: The disclosure relates to a latching mechanism for securing an enclosure case of a computer system to a rack. The rack has two pairs of spaced apart posts, each having attachment locations for supporting two cooperative oppositely facing bracket members. The bracket members include platforms for supporting the bottom of the case, such as a case for a CPU. Each member has supports for rotatably receiving a torsion shaft of a latch. Each shaft is formed with two spaced apart arms having outer portions that engage the upper corners of the opposite sides of the case at two locations on each side. The arms of each shaft are angularly displaced relative to each other along the shaft so that one arm is caused to engage the case before the other arm, and in effecting the holding contact of the arms a torque is placed on the shaft, which remains as a positive force latching the case to the bracket and hence to the rack.

Abstract: The disclosed invention relates to a computer system, including a crib device and chassis and including a U-shaped actuator and handle with distinct cam surfaces for installing and removing a hard drive to and from the chassis of the system. The drive is securable to the crib device, which has a handle that allows the drive to be carried to and away from the chassis. The crib device and chassis have cams and cam engaging surfaces that cause the crib device and drive to move to effect engagement and disengagement of the electrical connectors of the computer system and drive.

Abstract: A notebook computer which is controlled by a stylus executing gestures on the computer screen. The stylus and the computer include complementary electronic circuitry by which the proximity of the stylus tip to the computer is sensed. The proximity sensing is used to detect to approach of the stylus tip to the computer screen, and gestural commands are then entered on the screen by moving the stylus. The entry of a command is terminated by removing the stylus tip from proximity with the screen, which is detected by the computer, which then implements the command. Alternative methods of implementing the commands include time-outs and command termination buttons.

Abstract: The invention relates specifically to a process for the determination of local dye concentrations in animal and human tissues. Light from two different wavelength regions (I, II), one of which (I) has a window for hemoglobin, is irradiated into a subregion of the tissue and the diffuse reflectance (MIO, MIIO) determined. Then, in another step, by means of the diffuse reflectance in the first wavelength region and at least one tissue-type-specific standard basic diffuse reflectance curve obtained in advance for both wavelength regions a tissue-person-specific standard basic diffuse reflectance curve (SIIO) for the second wavelength region (II) is determined, and by means of the determined tissue-person-specific standard basic diffusereflectance curve (SIIO) and the measured diffuse reflectance (MIIO) in the second wavelength region (II) a value for the hemoglobin concentration (KHb1) is obtained.

Abstract: An improved pattern recognition system, using an improved method for merging low-level recognition information with auxiliary contextual information such as a Deterministic Finite Automaton (DFA). The system comprises a low-level shape recognizer for handwriting input, an English Language dictionary organized as a Trie (a special type of DFA), and software to merge the results of the two. An input of digitized handwriting strokes is translated into characters using the shape recognizer and the Trie in tandem, allowing the system to reject nonsense translations at the earliest possible stage of the process and without the overhead traversing the trie from the top with each translation.
