Abstract: This relates to methods for measuring irregularities in a signal and corresponding devices. The devices can include a PPG sensor unit configured to detect multiple occurrences of a given event in the measured signal(s) over a sampling interval. In some instances, the device can register the occurrences of the events. In some examples, the device can include one or more motion sensors configured to detect whether the device is in a low-motion state. The device may delay initiating measurements when the device is not in a low-motion state to enhance measurement accuracy. Examples of the disclosure further include resetting the sample procedure based on one or more factors such as the number of non-qualifying measurements. In some examples, the device can be configured to perform both primary and secondary measurements, where the primary measurements can include readings using a set of operating conditions different from the secondary measurements.

Abstract: A hose hanger apparatus includes a hose supporting body and a hose retainer. The hose supporting body has mounting structure to enable the hose supporting body to be mounted to a wall in an operative position in which a hose supporting surface faces generally upwardly and extends outwardly from the wall. The hose retainer is movable between retaining and releasing positions. In its retaining position, the hose retainer extends upwardly adjacent the hose supporting surface in spaced relation from the wall to inhibit the upper portion of the coiled hose from moving off the hose supporting surface without first raising the hose to a height sufficient to vertically clear the hose retainer. In its releasing position, the hose can be removed from or mounted onto the hose supporting surface without the need for first raising the hose to a height sufficient to vertically clear the hose retainer.
