Patent number: 10399083Abstract: A flow disrupter in a tube chamber of a tube assembly for homogenizing sample materials includes a flow-disrupting body that extends generally transversely into the tube chamber and divides the tube chamber into two sub-chambers. The flow-disrupting body includes at least one narrowed flow passageway through which the sample flows back and forth in both axially reciprocating directions as the tube assembly is vigorously shaken at high speeds faster and more reliably than what can be accomplished by hand shaking. And the flow-disrupting body includes at least two flow-interrupting surfaces facing generally in opposite axial directions and against which the sample impacts in each respective axially reciprocating direction as the tube assembly is vigorously shaken. In this way, the vigorous high-speed shaking of the tube assembly including the flow disrupter results in significant particle-size reduction of the sample by mechanical shear, fluid shear, cavitation, and/or pressure differentials.Type: GrantFiled: January 6, 2015Date of Patent: September 3, 2019Inventors: Karl Jahn, Voya Vidakovic, John Hancock, Thomas Gray

Publication number: 20190072507Abstract: A probe includes a base extending lengthwise between a proximal end and a distal end of the probe. A humidity sensor configured to measure a humidity value is disposed at the distal end. A temperature sensor configured to measure a temperature value has an ambient temperature sensing element that is spaced apart from the humidity sensor by a portion of the base and is disposed between the proximal end and the distal end. An interface disposed at the proximal end is configured to output a data signal indicative of humidity and to receive a power signal for heating the humidity sensor. Electronics is disposed on the base past the interface in a direction away from the proximal end and is coupled to the temperature and humidity sensors. The electronics is configured to provide the data signal to the interface as a function of the temperature humidity values.Type: ApplicationFiled: September 5, 2018Publication date: March 7, 2019Inventor: Karl Jahn

Patent number: 10055908Abstract: A method and system for improved driver reward display functionality. A driver reward is calculated based on inputs, such as freight fuel, fuel economy, and % idle. The driver reward system configures and displays a primary driver reward image for various menu selections. The primary driver reward image is configured to indicate whether the driver reward is at full penalty, partial penalty, neutral, partial bonus, or full bonus. The image is displayed in one color if above an expected value and another color if below the expected level. Images that indicate to the operator of the vehicle the impact of each input on the overall driver reward or whether each input is improving or worsening may be displayed. A secondary driver reward image may also be displayed to indicate a specific bonus or penalty in miles per hour and speed limit.Type: GrantFiled: July 8, 2016Date of Patent: August 21, 2018Assignee: PACCAR IncInventors: Zachary Slaton, Steven Karl Jahns, Josef Lotz, Jennifer Kim, Jason Morrow, John William Arthur Doll

Patent number: 9988049Abstract: An on-board vehicle computer system for a vehicle includes at least one processing unit and a memory having stored therein computer-executable instructions configured to cause the on-board vehicle computer system to implement various aspects of a predictive cruise control (PCC) system. In one aspect, the computer system provides a plurality of available speed control bands in a PCC system, and the available speed control bands are selectable by an operator of the vehicle. In another aspect, the computer system provides an upper speed margin and a lower speed margin for a PCC system, and the upper and lower speed margins are adjustable by an operator of the vehicle. Related notifications may be presented via an operator interface (e.g., a touchscreen display provided in a vehicle dashboard or other easily accessible area).Type: GrantFiled: July 8, 2016Date of Patent: June 5, 2018Assignee: PACCAR IncInventors: Zachary Slaton, Floris van der Meijs, Steven Karl Jahns, John William Arthur Doll, Josef Lotz, Andrew Paul Harbach, Wesley M.

Patent number: 9110493Abstract: A device, sometimes referred to as a clutch brake warning indicator, that provides feedback, which may be tactile, audible or visual, to the vehicle operator as the clutch pedal is nearing the point of its stroke where the clutch brake will be engaged. In use, the feedback clutch brake warning indicator will assist the driver against applying the clutch brake during shifting operations, which can cause severe damage to the clutch.Type: GrantFiled: March 6, 2013Date of Patent: August 18, 2015Assignee: PACCAR IncInventors: Edward P.
