Publication number: 20240103555Abstract: Sense mirror circuitry receives a voltage signal having values corresponding to a magnitude of a measured current. Responsive to the values falling within a first predefined range, the sense mirror circuitry outputs a current at a first predefined magnitude that corresponds to the first predefined range. Responsive to the values falling within a second predefined range, the sense mirror circuitry outputs a current at a second predefined magnitude different than the first predefined magnitude and that corresponds to the second predefined range.Type: ApplicationFiled: September 23, 2022Publication date: March 28, 2024Inventors: Brian D. Rutkowski, David John Rutkowski

Publication number: 20240053175Abstract: Systems, apparatus, and related methods for vehicle sensor calibration are disclosed. An example vehicle includes a sensor including an output; sensor interface circuitry including a transistor, the sensor interface circuitry communicatively coupled to the output; and processor circuitry communicatively coupled to the sensor via the sensor interface circuitry. The processor circuitry is to cause the transistor to activate to electrically couple the output to one of (a) a ground potential or (b) a voltage source associated with a voltage different than a voltage corresponding to an output voltage range of the sensor; and cause a code to be transmitted to the sensor. The sensor is to perform a calibration in response to the electrical coupling of the output to ground and receipt of the code.Type: ApplicationFiled: August 10, 2022Publication date: February 15, 2024Inventors: Brian D.

Patent number: 7195592Abstract: An improved surgical retraction apparatus (and corresponding method of operation) includes a plurality of rigid retraction members disposed about a central axis that move radially with respect to the central axis between a closed state and an open state. In the closed state, the retraction members form a central opening that is adapted to closely fit around the tubular section of a surgical port device. In the illustrative embodiments, a planetary gear train, cable assemblies and lever arms may be used to control radial movement of the retraction members with respect to the central axis.Type: GrantFiled: January 27, 2004Date of Patent: March 27, 2007Inventors: Sundaram Ravikumar, John Rutkowski
