Methods, apparatuses, and embodiments related to a technique for controlling channel usage in a wireless network in a multi-band wireless networking system. In a wireless network with multiple wireless networking devices and one or more client devices, communications between the wireless networking devices occurs via a backhaul channel, and communication between the client(s) and the wireless networking devices occurs via a fronthaul channel. Based on interference characteristics of the wireless channels, a device determines a channel usage plan, and communicates the plan via the backhaul channel to the wireless networking devices of the wireless network.

A security element for an object surface separated by a vertical distance, in particular an object height, from a floor area, includes a longitudinally extending flat support body including a first and second flat side. The first flat side is designed to be placed on the object surface. A presence detector and an evaluation unit are mounted on the second flat side, and the support body is made of a flexible material. The presence detector includes a detection region spatially extending around the presence detector away from the first flat side. The detection region is formed by a near-field region, and the evaluation unit includes an electrical energy storage device. The presence detector forms a measuring unit including an electrical characteristic variable. The presence detector also includes at least two electrically conductive electrodes, the electrodes being formed substantially along the entire longitudinal extent of the support body.

Based on those characteristics, the topology of the wireless mesh network can change.

A system includes an energy production device, a tampering detection system comprising a plurality of sensors, and a control system in communication with the plurality of sensors. The control system is configured to detect a candidate for a tampering event, determine if the candidate is a tampering or a normal operational error by comparing a first order condition to a predetermined threshold, and, when the predetermined threshold is not met, comparing the candidate to a subsequent order condition until the threshold is met, and direct an undertaking of a countermeasure when the candidate is a determined tampering or undertaking a maintenance when the candidate is a determined normal operational error.

In accordance with an embodiment, a detection device includes: an infrared temperature sensor configured to provide a temperature signal associated with an heat emission of at least one individual within a monitored area; an electrostatic-charge-variation sensor configured to provide a charge-variation signal indicative of a variation of electrostatic charge associated with the at least one individual; and a processing unit, coupled to the infrared temperature sensor and to the electrostatic-charge-variation sensor, the processing unit configured to detect a presence of the at least one individual within the monitored area by receiving the temperature signal and the charge-variation signal, and jointly processing the temperature signal and charge.

A system may include a processor. The processor may be configured to receive a first indication indicative of presence of a person arriving at a location associated with a scheduled service. The process may also be configured to determine whether the first indication corresponds to an expected arrival time of the scheduled service. Additionally, the processor may receive activity data in response to determining that the indication corresponds to the expected arrival time. Further, the processor may receive a second indication indicative that the person has completed the scheduled service. Further still, the processor may determine whether the scheduled service is completed based at least in part on the activity data. Even further, the processor may transmit a service confirmation to a computing device associated with a property owner of the location in response to determining that the scheduled service is completed.

Methods, apparatuses, and embodiments related to a technique for managing interference of communication of a wireless network in a multi-band wireless networking system. In an example wireless network with multiple wireless networking devices and one or more client devices, communications between the wireless networking devices occurs via a backhaul channel, and communication between the client(s) and the wireless networking devices occurs via a fronthaul channel. In response to detection of electromagnetic interference, a wireless networking device attempts to manage the interference, such as by adjusting a parameter associated with circuitry associated with a radio of the wireless networking device, or by other disclosed techniques.

This disclosure relates to a method of detecting an occupancy state of a living space for controlling an on/off performance of an electrical apparatus. The method comprises using a motion sensor to send wave signal and detect wave signal reflected from a moving human body and using a dual sensitivity detection arrangement including a low sensitivity detection mode and a high sensitivity detection mode respectively performed for identifying the wave signal being a motion signal according to the electrical apparatus being in a turned-off state or in a turned-on state. The dual sensitivity detection arrangement enables the motion sensor to more precisely detect the occupancy state of a living space while minimizing a probability of the electrical apparatus being activated by a noise signal.
