Patents by Inventor Daniel Gronvall

Daniel Gronvall 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: 7100462
    Abstract: A method and device for mounting a sensor to a surface that is flat in one dimension and flat or curved in a second dimension. The mounting method results in stable self-centering attachment of the sensor to the surface across a wide range of radii in the second dimension of the surface. A fixed distance and angle between the sensor components and the surface is automatically maintained despite wide changes in the radius of the surface. An attachment means is provided that is secure, repeatable, and reusable. Additionally, a means of maintaining a clear unobstructed window between the sensor and surface is provided.

  • Patent number: 5960610
    Abstract: An improved method for bending an oximeter sensor which simplifies the manufacturing. The sensor is manufactured without a bend, but when it is packaged for shipping, it is bent and restrained in the bent position. The sensor is made of a material which has memory so that when the packaging which restrains it is removed for use, the sensor will retain a partially bent shape.

  • Patent number: 5810724
    Abstract: A reusable accessory for a sensor (such as a pulse oximeter or a plethysmograph) that allows close conformance between the sensor heads and the patient tissue to be measured. The accessory thus provides both a key advantage of adherent sensors (i.e. close tissue-sensor conformance) and a key advantage of rigid structure sensors (reusability). The accessory provides a structure for mounting the sensor heads, whereby the sensor heads can pivot about their respective points of attachment to the mounting structure within first and second voids, respectively, thereby allowing the sensors to closely conform to the patient tissue. In one embodiment, the mounting structure includes a spring containing two coils, and two frames surrounding the voids and connected to the coils, each frame having an end shaped to fit a portion of a sensor head and onto which a sensor head is mounted.

  • Patent number: 4998894
    Abstract: An environmental sealing connector housing which includes means for retaining the housing on the terminator and the connector both in the associated but unconnected state, and in the connected state is described and illustrated. More specifically, the sealing connector housing includes compartments within the housing which are sized to accept the tap port and connector combination as well as separate compartments which can retain the housing on the tap while providing a compartment for the connector when the connector is not connected to the tap. In addition, the housing is designed so that a 180.degree. rotation of the housing permits the same housing to be used on both connected and unconnected connector/tap combinations to serve as a means of avoiding tampering with or stealing of the signal emanating from the tap.
