  • Compact shunt for current measurement
    Patent number: 9201099
    Abstract: Conductive strips are stacked, insulated, folded, and formed into geometric shapes to provide a low resistance, low inductance, shunt, wherein the geometric shape readily enables cooling to reduce changes in resistance due to self-heating effects. One such geometric shape is attained by winding the conductive strips into a spiral. Another geometric shape is a shape resembling a wave. Both geometric shapes allow cooling by directing airflow from a fan across their surface portions. A variable-speed cooling-fan is controlled in response to measured temperature of the shunt, or in response to a measurement of the current through the shunt. Differential cooling may be employed by means of changing the amount of airflow across various portions of the shunt in response to measured temperature of the shunt.

  • Maintaining privacy in a multi-tenant cloud service participating in a federated identity platform
    Patent number: 9191384
    Abstract: Embodiments conceal or obfuscate tenancy in a multi-tenant cloud service participating in a federated identity platform. A cloud service receives a request for a document from a first entity. The request includes an identifier associated with a second entity. The identifier is compared to a set of tenant identifiers each corresponding to one of the tenants to determine whether the second entity is one of the tenants. Based on the determination, a fictitious response is generated and sent to the first entity. In some embodiments, the document conforms to identity management protocols such as the Security Assertion Markup Language (SAML) specification and the OpenID brand software.

  • LUGGAGE TRACKING METHOD AND APPARATUS
    Publication number: 20150195804
    Abstract: The claimed technology provides a new method and process for locating and sharing information regarding the location of checked-in luggage while traveling. As part of the claimed technology, a GSM device is placed into luggage to be checked in by the traveler at the airline counter. A mobile device such as a phone or tablet lets the traveler know that their luggage has arrived in sync with the air flight. If the luggage has not arrived, the claimed technology notifies both traveler and airline of the airport location of the luggage, and proactively triggers the airline to coordinate with the passenger for delivery of the luggage.

  • Method and apparatus for three-dimensional digital printing
    Patent number: 9061521
    Abstract: Techniques are presented for digital ink jet printing upon a substrate with a significant third dimension. Droplets in the range of 120 pL to 200 pL have been found suitable for substrates with variability, in the third dimension, of up to approximately 4 cm. A larger droplet can be generated by utilizing a plurality of drive pulses, each of which generates a smaller droplet, and having the plurality of smaller droplets combine in mid-air. The data to be printed can be derived from a 3D model and such 3D model can also be used to guide shaping of the substrate. The 3D model can be produced from 2D image data. If the 2D image data is a two-dimensional portrait photograph, a result, of using the present invention, can be a realistic portrait in the form of a bas-relief sculpture.

  • Methods and Systems for Energy-Efficient Communications Interface
    Publication number: 20150063494
    Abstract: In a high-impedance communications interface, driver energy consumption is proportional to the number of signal transitions. For signals having three or more distinct levels, it is possible for a signal driver to salvage energy from some downward signal transitions and reuse it on some subsequent upward signal transitions. To facilitate this energy-conserving behavior, communication is performed using group signaling over sets of wires using a vector signaling code, with the design and use of the vector signaling code insuring that energy availability is balanced with energy demand.

  • Passive vehicle suspension system providing optimal camber gain
    Patent number: 8882116
    Abstract: The present invention provides a passive vehicle suspension system providing optimal camber gain and avoiding the “bump camber” problem. This vehicle suspension system utilizes a conventional sway bar and a kinematic system to rotate the tire(s) of a vehicle in a direction opposite the roll of the vehicle during turning or cornering, for example. The kinematic design allows for adjustability and optimization, providing optimal camber gain. Although an automotive vehicle suspension system is illustrated and described, and, specifically, a racing or everyday automotive vehicle suspension system, the concepts of the present invention are capable of much broader applicability.
