  • Patent number: 7934849
    Abstract: A lamp unit includes a base having a Reed switch, a telescopic stem extending upwardly from the base, a light source fitted at the top of the step, and a rechargeable battery fitted around the stem and below the light source. A docking station includes one or more magnets, an upstanding ring, and positive and negative contacts disposed in the center of the upstanding ring. The base of the lamp unit defines an aperture configured to be positioned over the circular ring so that the lamp unit may rotate on the docking station. Rotation of the lamp on the docking station is arranged such that the magnets actuate the Reed switch for turning the light source ON or OFF.

  • Patent number: 7930135
    Abstract: A person's exercise monitored using an accelerometer to detect and count the steps of the person. Furthermore, acceleration profiling distinguishes walking from running and total distance covered in the exercise is estimated using different stride lengths for walking and running. The person's pace may be maintained using a music playback unit with an adjustable rate of playback to influence the pace of the person with the music tempo.

  • Publication number: 20090303702
    Abstract: A rechargeable lamp system (10) comprises a lamp unit (12) and a docking station (14) on which the lamp unit (12) may be placed for charging of a rechargeable battery (22) within the lamp unit. The base (18) of the lamp unit and the docking station are configured so that the lamp unit may be rotated on the docking station. Rotation of the lamp on the docking station is arranged to operate a reed switch (104) in the base (18) of the lamp unit for turning a light bulb (56) ON or OFF. The reed switch (104) is switched ON and OFF by one or more magnets (100) provided in the docking station (14). The docking station (14) defines an upstanding ring (130) in the centre of which are located positive (132) and negative (134) contacts. The base (18) of the lamp unit defines a aperture (136) which locates over the circular ring (130) so that the lamp unit may rotate on the docking station. A telescopic stem extends upwards from the base (18). The light bulb (56) is fitted at the top of the stem (50).

  • Patent number: 7418350
    Abstract: A method and apparatus for estimating a seismic velocity field from seismic data including time-amplitude representations associated with source-receiver locations spaced apart by an offset distance and having a midpoint therebetween, the seismic data being arranged into common midpoint (CMP) gathers associated with respective CMP locations. A control plane having an edge intersecting a plurality of the CMP locations is defined, an initial velocity field for the control plane is produced, the initial velocity field including a plurality of time-velocity values for each of the CMP locations; and an optimized velocity field for the control plane is produced by adjusting the time-velocity values for each of the CMP locations in response to trends, relative to offset distance, in time values, associated with common seismic events, until said optimized velocity field satisfies a condition.
