  • Publication number: 20080159280
    Abstract: A method, apparatus, and electronic device for achieving simultaneous communication between multiple protocols are disclosed. The method may include receiving with a telecommunication device a first message on a first communications network using a first communications protocol; simultaneously receiving with the telecommunication device a second message on a second communications network using a second communications protocol; assigning a first priority to the first message; assigning a second priority to the second message; and processing the first message and the second message in an order based on the first priority and the second priority.

  • Publication number: 20070183343
    Abstract: A method and system for facilitating command of a group determines a present rank protocol associated with users of an ad hoc wireless communication network. The method includes identifying at a first wireless device a second wireless device in operative communication with the first wireless device (step 805). A physical parameter measured at the first wireless device is then compared with a physical parameter measured at the second wireless device and wirelessly received at the first wireless device (step 810). A base rank of a user of the first wireless device is then compared with a base rank of a user of the second wireless device (step 815). A present rank of the user of the first wireless device is then determined relative to a present rank of the user of the second wireless device based on comparisons of the physical parameters and the base ranks (step 820).

  • Publication number: 20070078683
    Abstract: A method and apparatus for securely and controllably transferring medical information is provided. An electronic device, like a portable computer, personal digital assistant or intelligent medical monitoring device, is configured to communicate with a healthcare provider's server. The device receives both an authorization code and a medical treatment description from the health care provider. The authorization code permits the user to both view and make a single transfer of the medical treatment description to a medical treatment provider. The authorization code may be as simple as a security PIN, or it may be a digital right that enables software to be accessible to a user within the device. The device is then configured to either print a single copy or electronically upload the medical treatment description to the medical treatment provider. When printed, the medical treatment description may include a unique watermark or scanable barcode to verify authenticity.

  • Publication number: 20060287606
    Abstract: A method for detecting heart rate, the method including the steps of: receiving (100) a heart activity signal at an input of a Q-filter processor that includes at least a first and a second Q-filter; removing noise (300) from the heart activity signal using the Q-filter processor to generate a filtered heart activity signal; detecting (400) a heart activity pattern, that includes at least a first S1 or QRS at a first time and a second S1 or QRS at a second time, from the filtered heart activity signal; and determining (500) a heart rate value based on the time interval between the first S1 and the second S1 or between the first QRS and the second QRS.

  • Publication number: 20060089557
    Abstract: A plurality of sensor clusters are provided (61) wherein at least some of the sensor clusters are comprised of at least one light sensitive sensor and a plurality of light emitters. These sensor clusters are disposed (62) in close proximity to a subject user and, in a preferred approach, at least some of the sensor clusters are disposed substantially distal to one another. The light emitters are caused (63) to emit light and the light sensitive sensors are used (64) to detect interactions as between the subject user and the emitted light. These detected interactions are then used (65) to determine the user's heart rate. In a preferred embodiment, the sensed interaction information is dynamically modified as a reflection of how valid the information trajectory appears to be at any given time.

  • Patent number: 6930608
    Abstract: One or more items of apparel have a plurality of sensors (10, 11, and 12) disposed therein (either permanently or temporarily). These sensors sense physical states of the individual wearing the items of apparel and/or of the local environment. In one embodiment, multiple sensors sense, in alternative ways, a parameter that corresponds to a physical state of interest. Information from these alternative sensing approaches is co-processed to yield a resultant parameter value that can be used in various ways. In one embodiment, the parameter value is locally or remotely displayed. In one embodiment, the parameter value is used in comparison against risk thresholds to ascertain a degree of risk to the individual.

  • Patent number: 5386877
    Abstract: An apparatus (102) assists an earthmoving vehicle (104) in the fracture of material (106). The apparatus (102) includes a ripping structure (108) having at least one ripper (112) and one electrode (130). The apparatus (102) generates electrical energy and discharges the electrical energy into the material through the ripping structure (108).

  • Patent number: 5130598
    Abstract: An apparatus is provided for controllably connecting and disconnecting a piezoelectric actuator to and from an energy source to effect the displacement of a piezoelectric actuator for a fuel injector. Precise control of the timing and duration of the piezoelectric actuator is necessary to ensure that a proper quantity of fuel is delivered to each cylinder of an internal combustion engine. A charging and discharging means monitors the voltage level of the piezoelectric actuator, and the charging and discharging current of the piezoelectric actuator. Further, a smoothing means aids in leveling the charging and discharging current to better approximate a constant current to control the piezoelectric actuator providing a precise quantity of fuel to be delivered.
