Patents by Inventor Robert Chu

Robert Chu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11760165
    Abstract: A heating device for heating fluids, such as water or a liquid coolant, for application in electric or hybrid vehicles, where the absence of an internal combustion engine or its shorter time of use requires using heating devices for heating either the passenger compartment or other parts of the vehicle that require it. The heating device is provided with a configuration which limits the temperature to the temperature at which heat exchange occurs between the heat generation source and the liquid to be heated, such that the liquid does not generate precipitates, prolonging the service life of the device.
    Type: Grant

  • Patent number: 11619421
    Abstract: A continuous-flow heater is described, with a housing made from an aluminium-based alloy, in which a flow channel for a fluid to be heated extends from an inlet to an outlet, and a heating plate which is arranged in the housing, with a substrate made from steel, which carries heating conductor tracks, a frame embedded in a wall of the housing, wherein the heating plate forms one wall of the flow channel in the housing, and is welded to the frame.

  • Patent number: 7969685
    Abstract: A DFH (Dynamic Flying Height) type slider ABS design has a stable flying height and a DFH efficiency that is uniform across the entire disk surface. These properties are a result of embedding the read/write head and heater in a trapezoidally bridged micro-pad having a very small surface area. The micro-pad is surrounded by a wing-like structure that projects from a central rail in the ABS and the micro pad is connected to an inner edge of that structure by a bridge having a trapezoidal shape. The trapezoidal shape responds effectively to variations in air flow direction and pressure point as the slider moves across the disk surface and, as a result, provides the uniform DFH efficiency. At the same time, the projecting wings and adjacent topology help to direct the airflow around the micro-pad and provide the stable flying height.

  • Publication number: 20090262458
    Abstract: A DFH (Dynamic Flying Height) type slider ABS design has significantly improved DFH efficiency and a decreased sensitivity of flying height to both ambient conditions and disk surface variations. This is a result of embedding the read/write head and heater in a micro-pad having a very small surface area. The micro-pad is surrounded by a wing-like structure that projects from a central rail in the ABS. The micro-pad is separated from the central rail by a surrounding trench whose depth can be varied to tune the DFH efficiency. The small surface area of the micro-pad reduces the air pressure at the read/write head and the projecting wings and adjacent topology help to direct the airflow around the micro-pad.

  • Publication number: 20070168336
    Abstract: Method and apparatus for a searchable data service are described. The searchable data service may be implemented as a Web service with a Web service interface that allows the storage of locators and other attributes associated with entities stored in a data store in a searchable index. The attributes may be expressed as {name, value} pairs. The interface may allow client applications to query the searchable index to retrieve locators for entities in the backend data store according to the attributes associated with each locator. Search speed may be automatically optimized using, for example, indexes, query planning, and parallelism. The searchable data service provides a searchable index and is not a data store per se. The searchable data service separates searching and indexing of data from the actual storage of the data.
