Patent number: 8141443Abstract: A probe adaptor assembly includes a probe opening into which a probe can be inserted. The probe is held in place by a compression fitting such that the probe depth, with respect to a longitudinal axis of the assembly, can be adjusted prior to the compression fitting being tightened to secure the probe. A conduit adaptor port is provided. A lubrication fitting provides an opening for a lubricant to be injected into the assembly. The lubrication fitting is coupled to the probe opening so that the lubricant injected into the fitting can exit the probe opening in order to lubricate the system into which the probe is inserted. In one embodiment, the probe adaptor assembly is configured to replace a lubrication fitting for a bearing so that a temperature of the bearing can be monitored while also providing lubrication.Type: GrantFiled: March 6, 2009Date of Patent: March 27, 2012Assignee: Electro-Sensors, Inc.Inventors: Kris Paxton, Bradley D.

Patent number: 8115477Abstract: A 2-wire, loop-powered shaft rotational speed sensor device that outputs a 4-20 mA current in response to the shaft rotational speed. The device is comprised of a sensor (e.g., magnetic, optical) that senses an output from a sensor disk (e.g., magnetic, optical) and outputs a series of voltage pulses whose frequency varies with the shaft rotational speed. A microcontroller measures this pulse frequency and generates a digital code representative of that frequency. A digital-to-analog converter generates an analog waveform in response to the digital code. A loop-powered, voltage-to-current circuit generates the output current in response to the analog waveform.Type: GrantFiled: April 20, 2009Date of Patent: February 14, 2012Assignee: Electro-Sensors, Inc.Inventors: Kris Paxton, Bradley D.

Patent number: 7444751Abstract: The linear distance measurement apparatus comprises a non-driven, extendable/retractable arm mechanism that is mounted such that an arc movement of the arm describes a linear distance. A rotary sensor mechanism is coupled to the non-driven arm. The sensor measures the arc movement of the arm and translates the arc movement to the linear distance.Type: GrantFiled: September 28, 2007Date of Patent: November 4, 2008Assignee: Electro-Sensors, Inc.Inventors: Bradley D. Slye, Daniel E. Bisila

Patent number: 6816630Abstract: A system allows a user to create and process data forms using familiar word processing and data base computer programs. The invention allows for form creation without interfacing with custom form software, but instead uses a known word processing program interface. The user, therefore, can be more efficient and has the tools provided with the word processing program. The present system can extract data from completed forms. This is performed through a scanning operation and a template. The extracted data can then be placed in a commercially available database program for processing.Type: GrantFiled: May 22, 2000Date of Patent: November 9, 2004Assignee: Electro-Sensors, Inc.Inventors: Larry J. Werth, Richard W. McGuire

Publication number: 20040164751Abstract: A digital potentiometer device has a potentiometer, coupled to a reference voltage, that generates a voltage that can be varied. A programmable scaling function scales the reference voltage and the potentiometer's wiper voltage depending on stored user variables. An analog-to-digital converter converts the scaled potentiometer voltage to a digital value readable by a controller circuit. The controller circuit controls the scaling function and display of the potentiometer position with the user variables.Type: ApplicationFiled: February 24, 2003Publication date: August 26, 2004Applicant: Electro-Sensors, Inc.Inventors: Bradley D. Slye, George W. Edwards, Daniel E. Bisila

Patent number: 5473708Abstract: A pattern processing system associates image input patterns with desired response codes. The image input is stored in an image buffer as an addressable array of sample values. An address sequencer provides a sequence of addresses (or "address stream") to the image buffer and to a response memory. The next address provided by the address sequencer is based upon the current address and the state of the sample value stored in the image buffer at the location corresponding to the current address. Once the address sequencer repeats and address, the address stream is in a repetitive address loop as long as the image stored in the image buffer remains constant. The address loop continues to be generated since the address sequencer always produces the same next address based upon the same current address and the same sample value stored at that current address.Type: GrantFiled: August 16, 1993Date of Patent: December 5, 1995Assignee: Electro-Sensors, Inc.Inventor: Larry J.

Patent number: 4488110Abstract: There is provided a voltage monitor which monitors a first voltage. A means for providing a reference second voltage is provided. Also, a signal third voltage which is obtained from and is proportional to the first voltage is provided. A comparison amplifier for comparing the reference second voltage and the signal third voltage produces an output voltage which goes to a first polarity when the signal third voltage exceeds the reference second voltage and which goes to a second polarity when the signal third voltage is less than the reference second voltage. Also, there is provided at least one indicator and at least one driver amplifier which amplifies the output voltage and drives the indicator into a first state when the output voltage shows that the signal third voltage exceeds the reference second voltage, and drives the indicator into a second state when the output shows that the signal third voltage is less than the reference second voltage.Type: GrantFiled: December 29, 1980Date of Patent: December 11, 1984Assignee: Electro-Sensor, Inc.Inventors: Thomas F.
