A fault notification system comprises a plurality of tower sensor units and a central processing element. Each tower sensor unit includes a tower safety sensor and a tower processing element. The tower safety sensor monitors a rotation angle of a mobile tower and output a signal that varies according to the rotation angle. The tower processing element is configured to receive the signal, compare a signal level of the signal with a range of signal levels indicating a normal rotation angle, and transmit a message that a fault has occurred and request that each drive motor shut down if the level of the signal is out of the range indicating a normal rotation angle. The central processing element is configured to receive the message from the tower processing element and transmit a signal to each tower processing element to output a signal to instruct each drive motor to shut down.

The present invention provides a system and method for using a small, wireless gyroscopic sensor to monitor end gun operations. Further, the present invention provides a system and method for using an accelerometer to detect vibrations at the end gun. According to further preferred embodiments, the present invention includes a diagnostic application which receives gyroscopic sensor data and accelerometer data. The diagnostic applications of the present invention preferably include logic and threshold limits which are applied to the received data. The present system preferably provides notifications and warnings based on detected changes in rotational motion, orientation changes and vibration levels in and around the end gun.

According to some embodiments, an oscillating sprinkler system is provided that includes: a central tubular portion having at least one row of flexible nozzles; a cam plate located inside a peripheral wall of said central tubular member, said cam plate having a plurality of cam slots for adjusting positions of said flexible nozzles upon rotation of said cam plate within said peripheral wall; and said peripheral wall including a window via which an edge of said cam plate is observable during rotation of said cam plate such as to designate an extent of angular displacement of the nozzles based on the positioning of the cam plate within the window.

With the use of low cost microphones mounted near each nozzle, sound signatures of the nozzles may be captured and compared to a baseline calibration measurement corresponding to a substantially new nozzle to determine if the nozzle is worn out. Sound signatures may be periodically captured and compared to the baseline calibration measurement to provide a continuous indicator of wear out for each nozzle. The invention has the advantage of being relatively low cost with ceramic microphones, for example, and with little or no moving parts required.

Introduced herein are various systems and techniques for dispensing scents from a scent delivery system. The scent delivery system could be a self-contained unit that is attachable to a head-mounted display (HMD) or could be integrated into the HMD itself. The scent delivery system can be used to improve the realism of content (e.g., visual content, audio content) experienced via the HMD. More specifically, the scent delivery system can be configured to dispense one or more scents in response to determining a particular scene is being experienced by the user. Different scents can be dispensed based on characteristics of the content. In some embodiments, the scent(s) are held in capsules that are housed within the scent delivery system. The capsules may be readily replaceable by the user, which enables the scent(s) to be customized based on what content is to be shown or projected in the future.

Introduced herein are techniques for producing sensory stimuli that increase the realism of content experienced by a user. Several embodiments pertain to scent delivery system that are able to dispense scented material(s) to the user. A scent delivery system could be a self-contained unit that is attachable to a head-mounted display (HMD) or could be integrated into the HMD itself. The scent delivery system can be used to improve the realism of content (e.g., visual content and audio content) presented to the user. More specifically, the scent delivery system can be configured to dispense one or more scented materials in response to determining a particular scene is being shown. Different scented materials can be dispensed based on characteristics of the content. In some embodiments, the scented material(s) are held in capsules that are housed within the scent delivery system. The capsules may be readily replaceable by the user.

An application system component is provided in the form of a changeable application member such as a nozzle or a bell cup. The application system component includes a transponder for storing component data, from which the component data is readable, and a wear detection device for monitoring of the application system component. The wear detection device includes a wear mark and an optical detector.

A system includes a manual tool data system having a manual tool data monitoring system configured to monitor one or more manual tools, a manual tool data acquisition system configured to acquire data corresponding to one or more operational parameters of the one or more manual tools, a manual tool data analysis system configured to analyze the data acquired by the manual tool data acquisition system, and a manual tool messaging system configured to generate messages based on the data analyzed by the manual tool data analysis system.

A product dispenser holder comprises a dispenser holder body configured to receive a product dispenser that stores a supply of a product to be dispensed, an actuation sensor that senses actuations of the product dispenser, and an actuation button, such that when an actuation force is applied to a pump of the product dispenser, a substantially downward force is applied to the actuation button causing the actuation button to rotate substantially downwardly and actuate the actuation sensor to generate a dispenser actuation signal.

A method and device for indicating whether a dispensable product will require refilling prior to the next scheduled service interval includes tracking the amount of use over a first interval, and calculating a frequency based from the use over the first interval. The quantity remaining is compared with the required amount, which is the product of the number of weeks in the service interval and the calculated frequency. Thus, when the quantity remaining is less that the required amount, a warning will be provided to indicate that the dispensing product should be replaced, as it will be empty before the next service interval.
