  • Patent number: 5729116
    Abstract: An apparatus and method of recognizing a shunt caused by formation of dendrites in a rechargeable lithium battery which comprises charging the battery with a charging current, sampling the charging current voltage of the battery at pre-determined time intervals in order to identify one or more point indicating onset of shunting, and terminating charging if the shunt or dendrite is indicated. If a shunt is not recognized charging is continued. Dendrite formation or the beginning of shunting due to such formation is indicated by any one of the following conditions: a negative gradient in sampled voltage values; a negative gradient in sampled steady open circuit values; and a negative gradient in the chemical polarization voltage values which may be calculated by sampling both the open circuit voltage soon after current interruption and steady open circuit voltages during a plurality of currentless phases.

  • Patent number: 5712989
    Abstract: In accordance with the present invention, a requisition and inventory management system is provided which employs both a host computer and a local computer which can be linked to permit two-way data communications in a real time environment. Each computer has an associated database which can be accessed by that computer. By accessing its respective database, each computer can build and transmit to the other computer communications blocks of data relating to a particular requisition of an item in Just-in-Time (JIT) inventory or to the management of the JIT inventory. The other computer can then use the received data to continue processing of the requisition or to update its JIT inventory records. Thus requisition records are created from a real-time interaction between the host and local computers, with each computer using data from its respective database in conjunction with information entered by a Customer Service Representative (CSR) operating the local computer.

  • Patent number: 5712979
    Abstract: A method and apparatus for tracking the navigation path of a user that has been directed to a second site on the WWW from a first site on the WWW. A URL is received at the second WWW site when the user is directed from the first site to the second site. At the second WWW site, information representative of an identity of the first WWW site is captured by identifying a first code in the URL. A destination web page is determined for the user, and a revised destination web page is formed by attaching a second code representative of the identity of the first WWW site into at least one selected web page link associated with the destination web page. The revised destination web page is then transmitted to the user.

  • Patent number: 5706441
    Abstract: A method and apparatus for objectively assessing the complexity of health-care services delivered by each health-care provider within a group of health-care providers to patients serviced by the group of health-care providers. In-patient data records representative of inpatient health-care services performed for patients by health-care providers with the group of health-care providers are stored in a database. Out-patient data records representative of out-patient health-care services performed for patients by health-care providers with the group of health-care providers are also stored in a database. A plurality of sickness episode data records are built by combining information from the in-patient and out-patient data records. Each sickness episode data record corresponds to an individual sickness episode for which health-care services were performed for one of the patients by at least one health-care provider from the group of health-care providers.

  • Patent number: 5701883
    Abstract: An oxygen mixing arrangement for or in a pressure support ventilator, in which a modular oxygen-providing assembly is selectively insertable into a greater respiration apparatus. Mixing accuracy and controllability is maintained by using gas supplies that have a wide range of pressures. Further, oxygen leakage is minimized by connecting the modular oxygen-providing assembly at a point of the respiration circuit of the greater respiration apparatus that is downstream from a valving arrangement normally used for venting patient exhaust flow and for controlling system pressure by venting excess gas flow to the ambient atmosphere.

  • Patent number: 5694923
    Abstract: A valving arrangement for use with or for a blower-based ventilator system, such as a pressure support ventilator, and a pressure support ventilator having such a valving arrangement, in which blower output can be controlled in such a manner that desired levels of pressure are able to be provided without excessive waste of blower output flow. In one preferred embodiment, a first valve is provided that serves to restrict blower flow, without venting the same from the system, along with a second valve for relieving pressure as needed. Also contemplated herein are methods for controlling such a valving arrangement.

  • Patent number: 5692215
    Abstract: A system is provided for monitoring a user in a user living area. The system includes a system controller and an activity detection subsystem. The activity detection subsystem monitors a daily living activity of the user and provides information representative of the daily living activity to the system controller. The system controller includes a control circuit which generates a control signal in response to the daily living activity information obtained by the activity detection subsystem. Control information from the system controller is applied by way of a control information communication channel both to the activity detection subsystem and to a remote monitoring site. The activity detection subsystem may be a system for determining the movement of the user around the home, medication compliance by the user, problems with usage of stoves or other potentially dangerous appliances, and selected auxiliary appliances.
