  • Publication number: 20020123779
    Abstract: Methods and apparatus for providing a sufficiently stable power to a load in an energy transfer system that transfers energy from one side of a physical boundary to another side of the boundary. In one example, a power supply and a primary winding are located on a first side of a physical boundary (e.g., external to a body), and a secondary winding and the load are located on a second side of the physical boundary (e.g., internal to the body). A primary voltage across the primary winding is regulated so as to provide a sufficiently stable output power to the load notwithstanding changes in the load and/or changes in a relative position of the primary winding and the secondary winding. One aspect of the invention relates to energy transfer methods and apparatus for use in connection with the human body. In particular, one example of the invention includes a transcutaneous energy transfer (TET) system for transferring power from a power supply external to the body to a device implanted in the body.

  • Publication number: 20020121683
    Abstract: An semiconductor device package (10) with improved thermal properties that limits unwanted parasitics and provides a more consistent distribution of parasitics from one device to another. The package of the present invention (10) is extremely compact and uses, in one embodiment, a minimal length of bond wires (20 and 22) between the terminals (14 and 16) and the attached device (30). The path length of the package (10) is reduced so as to represent only some fraction of a wavelength relative to the terminals (14 and 16) of the package (10). By reducing the length of the bond wires (20 and 22) and selecting the appropriate dielectric constant of the encapsulant (12), the invention provides a package (10) with a unique hexagonal structure that limits the effects of parasitics and provides good thermal dissipation. In a second and third embodiment of the present invention, the semiconductor device package (10) is useful in optoelectronic devices such light emitting diodes with an anode (71) and a cathode (72).

  • Publication number: 20020121463
    Abstract: An apparatus and method for removing lightweight particulates during processing of a primary material. The apparatus includes a classification tank having an inlet, an outlet and a plurality of settling stations located therebetween. A slurry of fluid and particles is introduced into the inlet and directed towards the outlet. As the slurry traverses along the classification tank, particles come out of suspension at the settling stations according to weight and to a lesser degree, density. The composition as well as the quantity of particles at the settling stations is periodically inspected. If particles deposited at a particular settling station are more or less the same size, and if they have accumulated in sufficient quantity, they are discharged to a flume which directs them to preselected collection areas.

  • Publication number: 20020122714
    Abstract: A Bulk Mail Container (BMC) unloader uses a simple crossed four bar-linkage to move a predetermined point on a BMC unloader in a substantially straight line while the overall BMC unloader rotates about that predetermined point so as to upend the BMC container. This takes advantage of the crossed four-bar's substantially straight-line motion over a limited range of its motion, as well as the rotational motion of the particular unloader link disclosed herein. This is advantageous for unloading. In use, a BMC container is simply rolled into the BMC unloader, and the entire combination of the BMC container and BMC unloader is then actuated to produce substantially straight line motion along a suitably selected “center” point of the BMC unloader while the overall combination rotates about the center point so as to upend the BMC for unloading.

  • Publication number: 20020124067
    Abstract: Context aware computing systems and methods are described. In one described embodiment, devices and methods are provided that are context-aware (in one example—location-aware) in that they provide for the application and enforcement of various policies as a function of context. Specifically, various computing devices, through the described methodologies and structures, are able to automatically determine their context. Once context is determined, a collection of policies can be evaluated to provide a resultant set of policies that apply to the given context. The resultant set of policies are then enforced, typically via the device's operating system. Policy enforcement can involve promulgating new settings or state to applications that are executing on or off the device. Advantageously, the devices and methodologies can adapt the resultant set of policies as the device's context changes so that the policies can be dynamically determined and enforced automatically as the device's context changes.

  • Publication number: 20020122566
    Abstract: An apparatus for embedding data in information material, the data being a plurality of data items each having a different relative importance. The apparatus comprises an encoding processor operable to encode each of said data items, and a combining processor operable to combine said encoded data items with said information material. The information material provides a limited data embedding capacity, as a result for example of the limited bandwidth of the information material itself. Each of the data items are encoded and embedded to the effect that a proportion of the limited data embedding capacity is allocated to the encoded data items in accordance with the relative importance of these data items. As such, for example, an amount of error protection given to each of the data items can be arranged in accordance with the importance of the data items, whilst still satisfying the limited data embedding capacity.
