Patents by Inventor Randall Welch

Randall Welch 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: 9408573
    Abstract: A patient interface for a reusable optical sensor, the patient interface including a compliant element defining a pocket having a lower wall defining an opening therethrough, the pocket being configured to removably receive the reusable optical sensor. The compliant element includes a first wing and a second wing configured for conformal placement on a patient's body. A condition of a patient may be monitored by inserting an optical sensor into a patient interface, applying the patient interface to the patient, obtaining a measurement with the optical sensor related to the condition of the patient, removing the patient interface from the patient, and removing the sensor from the patient interface.

  • Patent number: 9384925
    Abstract: The various embodiments of the present invention relate to remote pneumatic (bellows-action) actuators for switching applications, which are preferably sterile and/or disposable. When compressed, the bellows-action actuator provides a pulse of air pressure sufficient to actuate a remotely-located pneumatic switch configured to turn on/off an electrical, mechanical or optical device. The pulse of air pressure is propagated along a non-conducting tube, thereby substantially reducing the risk of e.g., electric shock or O2 ignition/combustion associated with conventional electric switches in wet, hazardous or medical environments.

  • Patent number: 7942459
    Abstract: A mounting device for a line replaceable unit in an aircraft, and a method for using the same. The mounting device provides for easy installation and removal of a line replaceable unit from overhead mounting apparatus or mounting rails in an aircraft, in particular, an Airbus. The mounting device includes a fixing block having a least one opening, and at least one assembly including a shaft portion passing through the opening, a clamping element and a visual position element whose orientation indicates an orientation of the clamping element. The assembly is operable such that the clamping element secures the device to a component of the vehicle when positioned in a first position, and releases the device when positioned in a second position, and the visual position element provides an indication of whether the clamping element is in the first or second position.
