  • Publication number: 20110244890
    Abstract: To enable enforcement and monitoring of safety regulations, a system records events of broadcast communications from a driver's or machine operator's mobile communication device. The events may be annotated with other fact or circumstances, such as time, duration, speed of vehicle, motion of vehicle, type of communication, or mode of communication. The event may be determined through use of direction receive only antennas capable of receiving only those signals aligned with the antenna, signals not aligned with the direction of the antenna are not received and thus do not create a recordable event. The recorded event may be broadcast to an organization or person in real time or may be retrieved periodically. The event may also produce an alert for persons or other operators proximate the vehicle or machine.

  • Publication number: 20110163110
    Abstract: An improvement to a dispenser of pressure-sensitive notes or marking flags includes the addition of an adhesive layer and a backing layer to protect the adhesive layer. The adhesive layer allows the temporary adhesion of the dispenser to books, desks, folders or other devices in which such notes or flags are applied by the user, resulting in increase convenience.

  • Publication number: 20110166830
    Abstract: Acoustic energy (sound) released by a liquid changes upon boiling and increases in some manner as a function of the boiling intensity. Detecting and quantifying the sound emitted from the boiling liquid with a sensor and processor enables a system to not only detect the boiling of a liquid but to assess the relative intensity of the boiling. Incorporated in a feedback loop, any heat source used to boil a liquid may be manipulated to control the boiling of a liquid and avoid the uncertainty associated with control based on temperature only.

  • Publication number: 20110159920
    Abstract: Mobile devices may minimize the radiation exposure to users by controlling the distance between the user, specifically the head, and the mobile device to a minimum distance. The reduction in exposure is realized due to the operation of the Inverse Square Rule on electromagnetic signal from the mobile device recognizing there is a steep fall off of signal strength resultant from increased distance between the head of the user and the source of the signal. Embodiments increase and maintain operational distance between the user and the broadcast device to reduce signal absorption. Enabled mobile devices increase and maintain the operational distance by detecting when the distance is breached by a variety of methods and then alerting the user. Sound and electromagnetic waves may be used to determine the proximity of the mobile device to the user, in addition image processing typically resident on some mobile devices may also be used to determine proximity to the user.

  • Publication number: 20110157859
    Abstract: A method and system for protecting a user from exposure from radio waves emitted from a wireless transmitter include at least a layer of dielectric material to operate on the radio wave through reflection, refraction, diffraction, absorption, polarization and/or scattering of the wave. The characteristics and arrangement of multiple layers of shielding on portions of or all of a face plate may significantly reduce exposure to electromagnetic waves and the deleterious effects associated with over exposure. The shielding can be applied subsequent to manufacture, during manufacture or incorporated into structures which may form the transmitting device.

  • Patent number: 7721704
    Abstract: A reciprocating piston engine wherein the movement of a piston within the combustion chamber creates vortices in the fluid within the chamber and wherein the orientation of the vortices is more normal to the axis of movement of the piston than parallel to the axis of movement of the piston. The vortices may be created by a device for attachment to the crown of a piston or by the configuration of the crown of the piston. The vortices may be created by a plurality of vanes extending outwardly from the center of the piston to the periphery thereof.

  • Patent number: 7182395
    Abstract: A system and method for deflecting the wind which would otherwise impinge upon the closed tailgate of a pickup truck, the deflector being mounted on the tailgate to preserve cargo space, including a spoiler and including a pair of relatively slidable rigid panels for deflecting the wind. The lower, forward panel overlies the upper rear panel and the relative position of the two panels is controlled by a scissors jack. The position of the distal end of the lower, forward panel is maintained adjacent the truck bed by a gust strap.
