Abstract: Techniques for determining bathroom occupancy are disclosed herein. In this regard, one or more sensors may determine whether a plumbing fixture is in use. When a plumbing fixture is in use, the one or more sensors may trigger a visual cue that indicates that the plumbing fixture is in use. Additionally, the one or more sensors may send (e.g., transmit) information indicating that the plumbing fixture is in use to one or more computing devices. The information may include a start time of the fixture's usage, an end time of the fixture's usage, a duration of the fixture's usage, etc. The computing device may analyze the information from a plurality of fixtures associated with a location and present the analysis to a user, for example, via a dashboard.

Abstract: A mosaic distributed combined interval magnetization method includes: arranging a magnetization module including magnetic sources disposed at both ends of a yoke and having opposite magnetic properties; arranging a magnetic sensor disposed between the two magnetic sources, where the magnetic sensor is used to detect changes in a direction of a magnetic field of the test piece under detection; wrapping the yoke and the magnetic source to form a non-metallic wrapped structure of a detection component, where the magnetization module is divided into a first magnetization module and a second magnetization module which is symmetrically disposed about a center of the first magnetization module. The method solves the problem of inaccurate detection signals caused by defect diversity, thereby ensuring that defect classification and defect quantification will not occur during subsequent data analysis, which otherwise leads to problems such as unclear defect classification and inaccurate defect quantification.

Abstract: A battery-free flushometer includes a combination of a power generation system, a power storage system, and/or a power management system to enable the flushometer to operate without the need for connection to an external power source, changing spent batteries, or recharging spent batteries using an external power source, as well as structures supporting this functionality. The flushometer may include a valve assembly. The power generation system may include a hydraulic turbine assembly positioned downstream of the valve assembly and configured to generate power using the water discharged through the outlet, and/or a photovoltaic cell configured to generate electrical power by converting light energy to the electrical power. The power storage system is electrically connected to the power generation system and includes a power storage device to receive and store electrical power generated by the power generation system.

Abstract: An automatic flush actuator unit is configured for connection to a first pressure-assist flush tank having a first mounting structure and a second pressure assist flush tank having a second mounting structure different from the first flush tank. The unit includes a housing for connection to the first and second flush tanks, having first and second sets of mounting holes for connection to the the first flush tank and the second flush tank, a motor, an actuator moveable to actuate a flush valve, and a gear assembly to transfer power from the motor to the actuator.

Abstract: The present disclosure describes a sensor comprising a first transmitter, a second transmitter, and a receiver. The first transmitter may be configured to emit first light via a first diffractive or refractive material, and the second transmitter may be configured to emit second light via a second diffractive or refractive material. The first diffractive or refractive material and/or the second diffractive or refractive material may be configured to deflect and/or shape light to focus the light in a detection zone. Light reflected by an intended target may be received (e.g., detected) by the receiver. Upon detecting a target, the sensor may cause a device to perform an action. The sensor may be deployed in a plurality of devices, including Internet-of-Things (IoT) devices that have WiFi capabilities. The WiFi capabilities may comprise a bridge-less architecture that allows the IoT devices to communicate with cloud services for remote monitoring purposes.

Abstract: A light ring assembly for a bathroom fixture. The light ring may illuminate one or more light sources in a predetermined sequence and/or in an overlapping manner to create a pulse of light that traverses the circumference of the light ring. Different patterns, colors, and/or sequences of light may be used to convey messages and signals to owners, maintenance, and/or users.

Abstract: A hybrid sensor for calibrating a primary active infrared (IR) sensor to more accurately locate, continuously calibrate, and conserve energy by more accurately detecting via the active IR detection is described herein. The hybrid sensor includes one or more infrared sensors and one or more time-of-flight sensors. The time-of-flight sensor may remain in a dormant state (e.g., low power or sleep mode) until the one or more infrared sensors detect an object. In response to detecting an object, the time-of-flight sensor may be activated to obtain several measurements of the object. After obtaining the measurements, the time-of-flight sensor may return to its dormant state. The hybrid sensor may use the measurements obtained by the time-of-flight sensor to calibrate the one or more infrared sensors to provide more accurate measurements on an object-by-object basis.

Abstract: An optical system includes one or several passive optical detectors sensitive to ambient (room) light for controlling, for example, the operation of automatic faucets or automatic bathroom flushers. The passive optical sensors provide signals to flow controllers, including control electronics and flow valves and require only very small amounts of electrical power for sensing users of bathroom facilities, and thus enable battery operation for many years. To control the operation of automatic faucets or automatic bathroom flushers based on ambient light, the controller executes novel algorithms.
