Patent number: 11785883Abstract: Mowing systems include a mower and a remote control unit such as a handheld unit, between which is provided 1- or 2-way communications. Components and features are included in the mower, the remote control unit, or both to enhance the safety, functionality, or user experience of the system's user/operator. Aspects of the invention relate to: an enable switch on the remote control unit that requires activation within a specified time before activating a drive system or PTO unit; sharing diagnostic information between the mower and remote control unit and emitting user-detectable warnings in response to the shared information; reducing a danger level of the system when a proximity between the mower and the remote control unit is too small; and using inclinometers in the mower and the remote control unit to control operation of the mower based on tilt angles of both the mower and the remote control unit.Type: GrantFiled: January 21, 2022Date of Patent: October 17, 2023Assignee: Embankscape Equipment LLCInventor: Michael D.

Patent number: 11653593Abstract: Mowing systems include a remote control unit such as a handheld unit for use with a mower, between which is provided 1- or 2-way communications. Components and features are included in the mower, the remote control unit, or both to enhance the safety, functionality, or user experience of the system's user/operator. One aspect relates to a handheld unit having a logic-implemented safety interlock for a PTO switch and/or a speed switch to prevent such switches from becoming active simultaneously with an enablement command for the PTO unit and/or drive unit of the mower. Another aspect relates to incorporating an inclinometer and/or motion sensor such as an accelerometer into the handheld unit, and controlling operation of the mower based on outputs) from such sensor(s). Another aspect relates to providing a display or other visual indicator on the handheld unit, and displaying on the visual indicator an indication of a tilt angle of the mower.Type: GrantFiled: August 2, 2019Date of Patent: May 23, 2023Assignee: Embankscape Equipment LLCInventor: Michael D.

Publication number: 20220347684Abstract: A single-use valve arrangement that includes a valve housing, a diaphragm carried by the valve housing, a pressure sensor, and a controller coupled to the pressure sensor. The valve housing defines an inlet and an outlet, the inlet adapted to be fluidly connected to an outlet of a virus removal filter. The diaphragm divides the valve housing into a first chamber and a second chamber fluidly isolated from the first chamber. The pressure sensor is configured to measure a pressure change in the second chamber due to movement of the diaphragm responsive to a pressure change in the first chamber. The controller is configured to determine an actual leak rate of the filter based on the measured pressure change, the controller further configured to determine the integrity of the filter by comparing the actual leak rate to an expected leak rate of the filter.Type: ApplicationFiled: May 3, 2021Publication date: November 3, 2022Inventor: Michael D. Brandt

Patent number: 11465110Abstract: An inline buffer dilution system is provided that includes a first flow control valve fluidly connected to a supply of diluent liquid, second and third flow control valves fluidly connected to supplies of a first buffer and a second buffer, respectively, and a mixing pump fluidly connected to the first, second, and third flow control valves and configured to mix an amount of the diluent liquid, the first buffer, and the second buffer to produce a diluted buffer solution. The system further includes a backpressure control valve configured to generate a backpressure that promotes mixing within the mixing pump, and a controller configured to control the backpressure based on the amount of the diluent liquid, the first buffer, and the second buffer being mixed in the mixing pump, such that the mixing pump yields a minimum mixing threshold across a range of fluid flows.Type: GrantFiled: December 26, 2019Date of Patent: October 11, 2022Assignee: Asahi Kasei Bioprocess America, Inc.Inventor: Michael D. Brandt
