Abstract: A dispenser with use-based content delivery includes an indicator to present audio and/or video content that is delivered from a remote computer via a wired or wireless network. In addition, the dispenser is configured to monitor various operation parameters associated with the dispenser, as well as the physical attributes of its users. The dispenser uses such data to select informational content that targets the needs of each specific user, so as to communicate informational content in a highly-effective manner.

Abstract: A network enabled dispenser is configured to bidirectionally communicate with a remote computer system via a wireless network. The dispenser transmits operation data to the remote computer system upon the dispensing of material, such as soap. The remote computer system is configured to generate hygiene compliance reports, deliver informational content to the dispenser for presentation thereon, as well as to provide an interface where an administrator can adjust one or more of the dispenser's functions.

Abstract: A method and apparatus for optimizing the filtration of process fluid. The system provides establishing a peak flow rate of permeate through a filter and then engaging a filtering cycle in which process fluid is passed through the filter until such time as the flow rate of permeate through the filter reaches a predetermined level which is set as a function of the initial permeate flow rate. At that point in time, a cleaning cycle is entered, during which cleaning fluid is passed through the filter for such a period of time as is necessary to allow the permeate flow rate with the cleaning solution to stabilize. At that point in time, the processing of process fluid is recommenced and the process continues on a repetitive basis between the processing of process fluid and the cleaning of the filter.

Abstract: A beam of light is transmitted from a transmitter (30) which is broken as the moving fiber (22) passes through the beam. A receiver (32) receives the light and generates a signal in response thereto. The signal is processed to determine the status of the pattern generated by the moving fiber (22) of material. In response to changes in the status of the pattern, the rate at which the fiber is dispensed and/or the movement of the pattern can be adjusted as well as alarm conditions noted.

Abstract: An automatic speed control for a heavy duty vehicle includes a controller which regulates communication between a compressed air source and an air actuated throttle mechanism. The controller generates a control signal which is a function of a speed error signal and the position of the air actuated throttle to regulate the compressed air source. The speed error signal is calculated as the difference between a commanded speed signal and an actual speed signal. To generate the control signal, the error signal and throttle position signal are operated on by different lead-lag transfer functions. These lead-lag terms are thereafter combined with a proportional speed error term to yield the desired control signal. The system further includes a throttle control feature for powering auxiliary equipment when the actual speed signal is zero. Another feature of the control limits the commanded speed signal to a set value when it exceeds a predetermined limit.

Abstract: An automatic speed control for a vehicle having a source of compressed air, such as a heavy duty truck, includes a logic controller which controls a pair of solenoid valves to regulate communication between the compressed air source and an air actuated throttle. The controller is responsive to initiation of speed control by actuation of the appropriate switch by the vehicle operator to use inputs representing wheel speed (or engine speed) and the position of the vehicle throttle to generate an error signal. The controller compares the error signal with a signal representing a desired or memorized speed set by the vehicle operator and controls the air actuated throttle accordingly.
