  • Patent number: 6129678
    Abstract: A system for detecting a patient's susceptibility to arrhythmias and cardiac tissue abnormality is disclosed. The system consists of a computer, a display software loaded onto the computer that generates graphical user interfaces (GUIs), an electronic interface, and a plurality of electrodes. The electronics interface is in electronic communication with the computer, and further in electronic communication with the electrodes that are placed by self-adhesion at predetermined locations on a test subject. According to one aspect of the invention, the system enables a user, typically a medical professional, to initiate, with minimal input, certain diagnostic test involving observing a series of QRS complexes that are both biased with a subpacing current and unbiased. The QRS complexes are then compared and analyzed by the system to detect a patient's susceptibility to arrhythmias and cardiac tissue abnormality.

  • Patent number: 6127924
    Abstract: A security system includes a control center, a controller installed in a car, a plurality of base stations installed in gas stations and houses, and a releaser. When a car owner finds that his/her car has been stolen, he/she can make a telephone call to the control center. The control center is guided to call the controller through a pager network and command the controller to enter into a searching mode to transmit a searching signal to search for a base station. After a base station receives and confirms the searching signal, the base station transmits a control signal to activate the controller to stop supplying gas and electricity to the car whereby the car is locked and located. In addition, each base station is integrated with a home security and remote control system to enhance its capability.

  • Patent number: 6118538
    Abstract: The present invention is a light based detection system for providing a low cost, very fast and very accurate measurements of lead positions and heights for integrated circuit board components. The alignment detections systems of the present invention are preferably located on a component placement head. The detector is a linear or rectangular array of pixels. The light path between the light source and the detector array is directed by the optical components across one or more leads in a plane that is neither parallel to nor perpendicular to the seating plane of the component. The light path is directed across the relevant leads without substantial interference from the body of the component or the other leads not being measured. A digital processor analyzes the measurements of the light sensitive detector to determine positions and/or coplanarity of the leads.

  • Patent number: 6110886
    Abstract: The invention is based on the discovery of the fabric softening ability of fatty amines and dimethyl fatty amine oxides for washer based applications. These amine softeners are combined with other ingredients to form the softening compositions. The softeners will contain a second compound selected from the group consisting of acidic compositions, nonionic surfactants and anionic surfactants, and other ingredients can be added to enhance the character of the fabric softener. Solid cast fabric softeners within the invention include compositions having between 5 and 95 percent by weight citric acid. Citric acid has adventageous properties. These solid citric acid containing fabric softeners will include a cationic surfactant such as a quarternary ammonium salt. Other solid cast fabric softener compositions in the invention have a reducing agent for reducing any remaining hypochlorite bleach. This reducing agent is combined with a fabric softening compound in the composition.

  • Patent number: 6106186
    Abstract: A modular portable stage and floor system uses a small number of standardized modular components to construct a temporary or permanent platform that is easily adaptable to a wide variety of platform designs. The modular standardized components include a series of modular vertical and horizontal supports and a light-weight modular deck panel. The modular vertical and horizontal supports can be detachably coupled together in a slidably interlocked manner using a universal connector mechanism in to a support frame structure for supporting a plurality of modular deck panels. By using a small number of modular supports and a universal connector mechanism that is similar for all structural interconnections required to build the support frame structure, the modular portable stage and floor system is strong and stable, yet easily transported, assembled and disassembled.

  • Patent number: 6100823
    Abstract: A rotor position encoder is provided for an electrical machine having a rotor and a stator, the encoder including a coded disc having teeth of widths that vary in a repeating sequence and being arranged to rotate with the rotor past a sensor which outputs a signal corresponding to the coded sequence. By comparing the coded signal with an internally generated signal the position of the rotor can be determined at a first resolution level. In addition, a counter is enabled as each tooth is sensed and provides a second output signal at a higher resolution level indicative of the rotor position between successive teeth. For a multi-phase machine, a value representative of the rotor position relative to each phase is combined with the value representative of the incremental position common to all phases. High resolution rotor position encoding with simplified logic is thus provided.

  • Patent number: 6093993
    Abstract: A switched reluctance machine has a stator or rotor lamination with pole arcs that are wider than necessary to fulfill the starting requirement of producing torque in the required direction at every rotor angle. On this lamination, preferably the rotor lamination, the surface is continuously graded over the entire pole pitch so that the first derivative of air gap length with angle is continuous. This allows control of the harmonics in the torque/angle curve and enables the production of smooth torque as the rotor rotates.

  • Patent number: 6092057
    Abstract: An automatic process for use in point-of-sale credit card or debit card systems for taking corrective action based on information returned from the banking system and/or the point-of-sale system. The automatic process replaces the human clerk as the interface in control of action by the point-of-sale device enabling unattended operation. The automatic process includes the maintenance of a hot list for denying use of repeatedly rejected cards, stopping the automatic operation if the banking system denies point-of-sale device access, and allows for local proprietary cards to be used independent of the banking system.

  • Patent number: 6088616
    Abstract: An automated external programmable defibrillator (AED) with the ability to perform operational self-tests, determine whether a patient is undergoing cardial defibrillation, deliver an electrical defibrillation pulse, store data pertaining to the self-tests. Certain operational parameters are alterable by software installable in a computer. The operational parameters include second defibrillation shock energy value, the maximum shocks to be delivered during a rescue, whether the same energy will be delivered to the patient upon conversion to a shockable rhythm, whether the AED will automatically convert to daylight savings time, whether an electrode test will occur during the self-test, and whether ambient sound will be recorded during a rescue.
